Background Nowadays, since the older people are keeping and increasing their professional and social activity, the risk of injury in these patients is escalating. However, the results of polytrauma treatment among patients over 60 years old are worse than in the group of younger patients. This may be associated with the presence of concomitant somatic pathology, which worsens the prognosis of for survival among elderly and senile patients. In the modern literature, there is no description of effective tools for assessing the comorbid status in elderly and senile patients with polytrauma. Nevertheless, there are scales and indices of comorbidity developed for non-surgical patients. To increase the effectiveness of treatment of patients over 60 years of age with polytrauma and a several concomitant diseases, it is necessary to develop new or adapt one of the already created tools for assessing comorbid status.

Purpose of the study To assess the dependence of the mortality rate in a group of patients with polytrauma over 60 years of age on the presence of concomitant somatic pathology and its severity, calculated by the geriatric index of comorbidity.

Materia l and methods During the period from 2005 to 2020, 116 patients with polytrauma and chronic somatic pathology were treated at the Sklifosovsky Institute. The inclusion criteria for the study were the following: patients aged over 60 years old; или patients’ age over 60 years old; the Injury Severity Score over 17, the presence of concomitant somatic pathology in patients. The exclusion criteria were the lack of complete necessary information in the medical history, patients’ age being less than 60 years old. The Geriatric Index of Comorbidity was calculated for each patient. A retrospective analysis was conducted.

Results A Geriatric Index of Comorbidity of 3 or more in the elderly patients with polytrauma was found prognostically unfavorable for survival (p=0.005). When implementing the Geriatric Index of Comorbidity rating system, the presence of concomitant somatic pathology was found to have the greatest impact on elderly and senile patients with polytrauma and Injury Severity Score 18–24 (p=0.001).

Conclusion The system of calculating the Geriatric Index of Comorbidity is advisable to use for assessing the risk of mortality from concomitant somatic pathology and its severity in patients with polytrauma over 60 years of age.

Background We identified patients treated at our Burn Center over a 14-year period.

Material and methods The following data were studied: the annual and total number of patients, the number of patients admitted to the Intensive Care Unit (ICU) and the Burn Unit (BU), gender and age of the patients, the epidemiology of burn injury, percentage of total body surface area (TBSA) burned, percentage of inhalation injury, percentage of full thickness burns, mortality.

Results It was revealed that the annual number of patients averaged 730 (692; 747). The proportion of those hospitalized to the ICU was 35–49%, and 51–65% to the BU. These figures did not differ significantly (all p>0.05; Fisher exact test [FET]). The male to female ratio was 2.3-1.6:1. The age of the patients increased from 44 (31; 59) to 48 (33; 62) years (p=0.003; M–W test). The percentage of the etiological factors changed: flame burns accounted for 60% of cases in 2006 and 34% of cases in 2019 (p<0.001; FET). The number of patients with scalds increased from 18% in 2006 to 33% in 2019 (p=0.023; FET). The proportion of patients with inhalation injury without burns did not exceed 15% for the entire study period. Median burn area among all hospitalized decreased by almost twice from 2006 to 2019: total area from 12% to 7% TBSA (p<0.001; M–W test); superficial, from 10 to 6% TBSA (p<0.001; M–W); deep burns, from 9 to 3% TBSA (p<0.001; M–W). In patients in the ICU, the median of the total burned area was 20–25% TBSA, the area of superficial burns prevailed without a statistically significant difference between 2006 and 2019. (p=0.285; M–W test). The median area of deep burns gradually decreased by more than twice: from 15% TBSA in 2006 to 7% TBSA in 2019 (p<0.001; M–W test). For the period from 2006 to 2019 overall mortality in the burn center decreased from 16.7% to 7.4% due to a 2.4-fold decrease of mortality from 16.3% to 6.9% in the ICU (p<0.001; FET). In the BU, for the entire period it was 0.4-1.6%. In 2019, the highest mortality of 27% was observed in combined burns and inhalation injury (InI) followed by InI without burns (13.6%), and then came electrical injury (11.8%).

Conclusion For 14 years, mortality has decreased by more than twice. The highest number of deaths was observed among patients with skin burns and InI, InI without burns and electrical injury. Annual number of admissions in ICU and BU, gender ratio remained steady. The median area of total burns decreased by 2-3 times, the median area of deep burns in patients in the ICU decreased by 2 times. The median age of burn patients increased by 4 years and began to refer to the middle age group according to the WHO classification.

Abstract We analyzed the clinical condition of patients with COVID-19 of varying severity, changes in instrumental and laboratory parameters, and assessed the impact of the severity of the course of a new coronavirus infection on the outcomes of acute coronary syndrome.

AIM OF STUDY To study the mutual influence of acute coronary syndrome and the new coronavirus infection COVID-19 on the nature of the course and outcomes of the disease.

Materia l and methods In March 21, 2020 – May 31, 2021, 3 625 patients were treated for COVID-19, including 131 patients with acute coronary syndrome due to COVID-19 disease. All patients underwent a number of studies: computed tomography of the chest, electrocardiography, echocardiography, monitoring of biomarkers of myocardial damage, diagnostic coronary angiography and, if necessary, intracoronary therapeutic intervention.

Results Data on the distribution of patients with COVID-19 according to the presence or absence of ST segment elevation on the electrocardiogram and the degree of lung tissue damage, as well as information on mortality in these groups, are presented. The role of troponin I in the assessment of myocardial ischemia was analyzed. The direct dependence of its level on the volume of lung damage was found. The inverse relationship was shown between the degree of damage to the lung tissue and the indices of oxygen saturation in the blood. A poor prognostic value of low left ventricular ejection fraction in patients with COVID-19 disease has been described.

Conclusions The development of acute coronary syndrome in the course of COVID-19 significantly worsens the prognosis of the disease, which requires the development of algorithms for providing medical care to patients in this category, as well as maximum vigilance in their treatment.

BACKGROUND Currently, despite the optimization of diagnostic methods in order to predict the development of liver damage, improvement of treatment protocols, paracetamol poisoning is a serious problem in medicine, being the most common cause of acute liver failure worldwide.

AIM OF STUDY To determine the indications for the use of acetylcysteine in paracetamol poisoning and evaluate the effectiveness of the 21-hour protocol for its administration.

MATERIAL AND METHODS We examined 20 patients with acute paracetamol poisoning (15 women and 5 men), the median age was 21.5 (19.8–32.3) years. ALT and AST were assessed during the entire period of stay in the hospital, the time period from the moment of taking paracetamol to hospitalization and the beginning of the administration of ACC, the concentration of paracetamol in the blood, and mortality. According to the level of ALT and AST in the blood, the patients were divided into 2 groups: Group I consisted of 14 patients, in whom the concentration of ALT and AST during the entire observation period did not exceed 50 U/L; in Group II (6 patients), an increase in the level of ALT and AST in the blood of more than 50 U/L was observed. To assess the risk of liver lesion, the Rumack-Matthew nomogram was used. To compare the concentrations of paracetamol in the blood of patients, the paracetamol index was used.

RESULTS It was found that in 10 patients with a high risk of liver damage, who were treated with a 21-hour regimen of ACC administration, no hepatotoxic effect was found. The use of ACC according to a 21-hour protocol in patients with initially elevated ALT and AST levels of more than 50 U/L (n = 4) (25%) led to a rapid positive dynamics of laboratory and clinical parameters. It was found that in 2 patients, despite the introduction of ACC, the development of liver damage was observed. At the same time, the level of paracetamol in their blood was 6.6 and 10.6 fold higher than the “therapeutic” line of the nomogram, and the time from the moment of taking the drug to the beginning of the administration of ACC was 8 and 20 hours. High risk factors for the development of hepatotoxic effect in case of paracetamol poisoning are the time range from the moment of taking the drug to the beginning of the administration of ACC and the value of the paracetamol index.

CONCLUSION Indications for the use of acetylcysteine in acute poisoning with paracetamol is a high risk of liver damage. Its criteria are high doses, increased concentrations of ALT and AST when patients are admitted to the hospital; if it is possible to determine the concentration of paracetamol in the blood, an increase in the value of the paracetamol index is more than 1. The use of a 21-hour protocol of intravenous administration of acetylcysteine is effective in case of paracetamol poisoning and its early use in the complex of treatment almost always prevents the development of acute liver failure.

Abstract Respiratory tract trauma is not only the result of injuries to the chest and neck, but may be iatrogenic as well. Diagnosis of iatrogenic damage to the trachea is based on data from clinical and instrumental studies. Among the instrumental diagnostic measures, preference is given to early fibrobronchoscopy.

The aim of the study is to assess the possibilities of fiberoptic bronchoscopy in the diagnosis of iatrogenic tracheal injuries. Materials and methods. This study analyzed the use of fiberoptic bronchoscopy in 51 patients with suspected iatrogenic damage to the trachea. For iatrogenic ruptures of the trachea, the location on the posterior (membranous) wall and the longitudinal direction (100%), as well as location in the lower and middle thoracic sections of the trachea (71.4%), are typical.

Conclusion Bronchoscopy is a direct method for diagnosing this type of damage, which allows the location, size of the defect and tactics to be accurately determined.

Aim of study To develop a new safe and reliable method of fixing an epidural catheter (EC), to study and compare the results of this method of fixing EC in the subcutaneous canal using a modified spinal needle (MSN) and an adhesive tape with a standard method of fixing an EC using only an adhesive tape when performing the combined double-segment spinal-epidural anesthesia (CDSEA) in the surgical treatment of fractures of the bones of the lower limb.

Material and methods A comparative study of two methods of EC fixation was carried out in patients undergoing CDSEA during the surgical treatment of fractures of the bones of the lower limb. The patients were divided into two groups. The Group 1 (comparison, n=65), where EC was fixed at the site of epidural access with adhesive tape and the Group 2 (study, n=65), where EC was fixed in the subcutaneous canal using MSN and adhesive tape at the site of EC exit on the skin.

Results In the study group, where EC was fixed in the subcutaneous canal using MSN and adhesive tape at the site of EC exit to the skin, there were 32.3% fewer cases with clinically significant dislocation (more than 15 to 30 mm) than in the comparison group, where EC was fixed at the site of epidural access only with adhesive tape.

Conclusions A used spinal needle in a modified version can be used to perform EC in the subcutaneous canal. The dimensions of the MSN allow tunneling of the EC less traumatic and at a great distance from the site of the epidural access, which provides more reliable fixation of the EC, the number of cases with clinically significant + dislocation decreases, this allows for a longer and better postoperative epidural analgesia. This method does not solve all the problems of EC fixation; it is required to develop new methods of EC fixation, including fixation in the subcutaneous canal.

Abstract For the timely determination of the tactics of treatment of acute pancreatitis, it is necessary to predict the severity when the patient enters the hospital.

Aim of the study To assess the possibility of predicting the severity of acute pancreatitis using ultrasound markers, clinical scales.

Material and methods A retrospective analysis of the diagnostic results of 84 patients who were hospitalized for acute pancreatitis was carried out. The results of clinical-laboratory and morphological diagnostic methods obtained upon admission of a patient to a hospital in patients with varying degrees of severity of ap were analyzed. Clinical and laboratory data were analyzed using prognostic scales — marshall, ranson, sofa, bisap. The analysis of morphological changes in the pancreas during ultrasound and computed tomography was performed using the balthazar classification.

Results The sensitivity of clinical scales for determining the severity of ap was 67% on the sofa scale, 87.5% on the bisap scale, and 100% on the ranson and marshall scales. All patients (22) who had signs corresponding to the balthazar stage d and e upon ultrasound examination subsequently had a moderate and severe course of the disease.

Conclusion The use of ultrasonic markers of acute pancreatitis in conjunction with the data of clinical and laboratory scales makes it possible to predict the severity of acute pancreatitis.

The possibilities of computed tomography in the diagnosis of spontaneous hematomas (sh) of the soft tissues of the neck and chest and the features of their treatment are shown. Computed tomography with intravenous bolus contrast enhancement is the main method for diagnosing sh, which allows you to specify its exact localization, distribution, determine the structure and volume of the hematoma, the contrast agent exiting the contours of the vessel, and, taking into account the data obtained and the clinic, determines the tactics of treatment.

Stable sh does not require surgical treatment. In the case of a large volume of chest hematoma, compression syndrome, hemothorax, drainage is indicated. Unstable sh dictate the need for angiography and, if necessary, endovascular embolization.

Background poisonings with corrosive substances in russia retains a high proportion among acute exotoxemias. They are accompanied by severe homeostasis disorders with changes in hemorheological pattern in particular.

Aim of study To evaluate the effect of the enteral correction of homeostasis (ech) on the hemorheological patterns in patients with acute poisoning with corrosive substances.

Material and methods Patients with chemical burns of the mucous membrane of the esophagus of the 2nd-3rd degree and stomach of the 2nd-3rd degree who were treated at the n.v. sklifosovsky research institute for emergency medicine in 2017–2021 were examined. In 73 patients, ech was performed (study group), and 35 patients received standard treatment (comparison group). Indicators of hemorheological status were examined on the 1st, 3rd and 5th days in the course of ongoing therapy, as well as before and after intestinal lavage in patients of the study group. Statistical data analysis was carried out using the statistica 10 software package (statsoft, inc., usa).

Results The first stage of ech, characterized by the use of intestinal lavage, has no negative effect on hematocrit, plasma viscosity and erythrocyte aggregation indices.

The use of a glucosated enteral solution led to a decrease in plasma viscosity under normal hematocrit conditions at all follow-up periods. In patients of both groups, there was a decrease in blood viscoelasticity under conditions of high shear potential at all stages of the study, which indicates violations of the deformability of red blood cells. This process is more significant in individuals of the comparison group. The conducted studies have shown that standard treatment and ech for poisoning with corrosive substances have a corrective effect on the hemorheological profile aimed at stabilizing blood circulation, however, according to a number of indicators, the effect of ech is more pronounced.

Conclusion The program of enteral correction of homeostasis and standard treatment for poisoning with corrosive substances have a unidirectional effect on the indicators of the hemorheological pattern. In cases of application of the enteral homeostasis correction program, the outstripping improvement of the majority of the studied hemorheological parameters is seen.

Introduction Inhalation injury (ini) makes burn disease more severe. However, it remains unexplored what is the minimum area of the burn that can significantly aggravate of the course of ini.

The objective was to compare the incidence of acute respiratory failure (arf), pneumonia, and mortality between patients with ini and ini with superficial skin burns up to 3% total body surface area (tbsa).

Material and methods 125 patients with ini and i–ii degree skin burns up to 3% tbsa were allocated into 4 groups: ini without skin burns, ini with burns up to 1% tbsa, up to 2%, and up to 3% tbsa.

Results In the group with ini and skin burns up to 2%, the number of arf, pneumonia cases, and deaths did not statistically significantly differ from the ini group, however in group of ini and burns of more than 2% tbsa, there were more of those complications.

Conclusion Skin burns of i–ii degree over 2% tbsa increase the incidence of acute respiratory failure, pneumonia, and death in patients with ini.

Relevance the issues of patient care and quality management have acquired particular relevance in modern healthcare. Improvement in the clinical performance of medical technologies has led to a significant reduction in deaths and complications associated with the disease and side effects of interventions. As a result, the share of additional harm related to the process of providing medical services has become more noticeable. Accurate data regarding the type, frequency and severity of active threats and incidents they cause are needed to reduce the likelihood and severity of additional harm. In this respect, emergency medical care is the subject of special attention and is characterized by the greatest difficulty in terms of obtaining valid and relevant information about deviations associated with health worker performance, equipment operation and patient behavior.

The aim of the study was to explore the main epidemiological characteristics of medical errors and incidents associated with the provision of emergency medical care.

Material and methods We present a literature review followed by an analytical study of the epidemiology of incidents and active threats (including medical errors) that precede those incidents in various areas of emergency medical care. By an incident, the authors understood an event with a patient that was more related to the process of providing medical care than to the course of the disease or comorbid conditions which led or could lead to causing additional harm. Active threats included events that subsequently became the direct cause of the incident (medical errors and malpractice, mistakes and deviations in patient behavior, emergency situations in the physical environment). By the “mortality from adverse events”, the authors understood the proportion of deaths from adverse events among all hospitalized patients. By the concept of “lethality associated with adverse events”, the authors denoted the proportion of deaths from adverse events among all the patients affected by adverse events. The search for information was carried out for the period of 1995–2021 using the following medical databases: medline; cochrane collaboration; embase; scopus; isi web of science. For analysis, we used prospective and retrospective observational studies of high methodological quality, meta-analyses and systematic reviews. For the statistical evaluation of frequency characteristics, indicators of incidence, prevalence, and incidence density were used. The calculation of generalized frequency indicators for large samples was carried out with a 95% confidence interval.

Results The epidemiology of medical errors and incidents depends on the area in which emergency care is provided. For prehospital emergency medical care, there are 12.45 medical errors and 4.50 incidents with consequences for every 100 visits. In emergency departments, one in fourteen patients suffers additional harm which in 10.14% of cases has severe consequences, and in 3.18% of cases leads to unexpected death. In intensive care units, incidents related to the provision of medical care are recorded in every third patient in the amount of 1.55 per 1 patient. Of these, 58.67% of incidents are accompanied by harm, but the fatality associated with the incidents is only 0.77%. The prevalence of patients affected by incidents during the provision of anesthesia for children is almost 2 times higher than for adults (4.79% vs. 2.03%). At the same time, mortality due to anesthesia-related incidents in children is 11 times lower than in adults (0.27% versus 3.09%). The author draws attention to a number of factors contributing to the development of incidents during the provision of emergency medical care. These include environmental complexity, suboptimal configuration of the workspace, technological interface complexity, the effects of acute stress on performers, and organizational vulnerabilities. A special role was assigned to environmental complexity which was studied in detail both in terms of the complexity of the tasks being solved, and in connection with obstacles to solving problems. It was shown that the intensity of the influence of various components of environmental complexity is not the same in different departments providing emergency care. Particular attention was paid to the fact that organizational vulnerabilities reduce the effectiveness of protective mechanisms during the interaction of the human factor with a complex environment.

Conclusion The study showed that the provision of emergency medical care is associated with moderately high risks of incidents, including severe and critical consequences for patients. The main factor contributing to the development of incidents is environmental complexity which becomes much harder to counter under the influence of organizational vulnerabilities. Identification and registration of errors and incidents in units providing medical care is difficult due to the short time of contact with patients, the high speed of situation update, and the constant impact of chronic and acute stressors on staff. In this connection, the optimization and improvement of the efficiency of the system for recording errors and incidents in departments providing emergency medical care remains an area for improvement.

Background Acute mesenteric ischemia (ami) is diagnosed in 1 case per 5,000–15,000 operations associated with elective abdominal surgical intervention and in 1 case of 1,000 emergency laparotomies associated with the acute abdomen clinical features. Non-occlusive disorders account for 20-30% of all cases of ami. The absence of pathognomonic symptoms and syndromes, as well as specific laboratory markers of ami, determines significant difficulties in the early diagnosis of this disease, especially in critically ill patients.

Aim of study To identify the main laboratory markers of acute mesenteric ischemia applicable in the resuscitation and intensive care unit (ricu) based on a systematic literature review.

Material and methods A systematic search and selection of publications was carried out in march-april 2021 in accordance with the prisma system checklist (prisma, preferred reporting items for systematic reviews and meta-analyzes). The search used two databases: the cochrane library of systematic reviews (https://www.cochranelibrary.com) and the pubmed bibliographic database (https://pubmed.ncbi.nlm.nih.gov). Key terms in the search parameters were: acute mesenteric ischemia; bowel necrosis predictors; laboratory diagnostics of mesenteric ischemia. Search parameters were limited to the year of publication (not later than 2015). The main results of the review included patients with an established diagnosis of acute mesenteric ischemia, indicating the level of laboratory parameters (ph of mixed venous blood, lactate, d-dimer, white blood count, mpv, i-fabp, serum marker and alpha-glutathione-s-transferase, indicators of the coagulation and hemostasis). Case reports and editorial letters were excluded from the search.

Results The threshold value for serum l-lactate ranged from 1.05 mmol/l to 5.6 mmol/l. The sensitivity of serum lactate for the diagnosis of ami ranged from 34.7% (95% ci: 0.82–91.64%) to 89.51% (95.4% ci: 75.12–94.28%), and the specificity ranged from 47.3% (94.7% ci: 26.54–67.98%) to 94.5% (93.2% ci: 75.44–96.85%). The threshold level of d-dimer varied from 0.58 nmol/l to 7.84 nmol/l. The sensitivity of blood d-dimer for the diagnosis of ami was 72.6% (94% ci: 56.1–92.4%) to 99.7% (94% ci: 69.15–100%); the specificity ranged from 69% (95% ci: 7.41–33.63%) to 97.89% (95% ci: 90.42–98.1%). Parameters such as transaminases (ast, alt), mpv, ldh, d-lactate, serum amylase were not included in the review due to the lack of a sufficient number of studies.

Conclusion Today, there is no highly specific laboratory marker that could be considered the “gold standard” in the laboratory diagnosis of acute mesenteric ischemia. The most promising in predicting ami are serum levels of l-lactate and d-dimer.

The article highlights the problem of providing care for patients with acute coronary syndrome, given the high myocardial infarction (mi) morbidity and mortality among the youth population. The main method of managing acute myocardial infarction is reperfusion therapy, performing revascularization with percutaneous coronary intervention (pci) in the shortest possible time from the disease onset. Only rational and timely treatment can reduce mortality after mi, the frequency of its complications, as well the period of inpatient treatment and disability of the population.

Early and correct diagnosis of infective endocarditis (ie) of the right heart does not lose its importance due to the persistence of the problem of intravenous drug use and an increase in the number of surgical interventions on the heart. Septic pulmonary embolism (spe) is a typical sign of right-side ie, and, with a number of nonspecific respiratory symptoms in patients with fever, its detection by radiology allows to start a diagnostic search for ie and locate the primary embolic source in the right parts of the heart. The review examines the current state of the problem of right-side ie, morphology and clinical evidence, main ct signs and differential diagnostics of spe, including the context of the covid-19 pandemic.

Elvic vein injuries can occur with pelvic bone fractures, gunshot wound injury, iatrogenic injuries and lead to life-threatening bleeding. Ct is the main diagnostic tool in differentiating arterial from venous bleeding. Open surgical repair of venous injuries can be technically difficult. Endovascular treatment is an attractive alternative strategy. Embolization is the main method to stop arterial bleeding; balloon occlusion and stent graft implantation are also used. Arterial embolization cannot help in the situation of venous bleeding. The problem of endovascular treatment of pelvic vein injuries was not given enough attention. The purpose of this review is to summarize the available reports on the use of endovascular techniques in pelvic vein trauma and show the capabilities of the methods.

The article presents a case study with a detailed solution, reflecting the features of the clinical features of drotaverine poisoning, the principles of diagnosis and treatment of this condition at the prehospital stage. This type of educational technology is applicable both for practical training with elements of simulation training and for monitoring the level of training of medical personnel.

The study objective Is to present a clinical observation, describe the diagnostics and treatment of acute transmural myocardial infarction in a patient on the 8th day after childbirth

Material and methods A 31-year-old patient was hospitalized 3 hours after the onset of the disease on the 8th day after urgent spontaneous delivery at 38-39 weeks of gestation with a clinic of acute myocardial infarction in the intensive care unit. Based on the data of anamnesis, complaints, physical examination, results of instrumental and laboratory examination, the following clinical diagnosis was made: ischemic heart disease: acute transmural myocardial infarction of the anterior wall, septum and apex of the left ventricle; atherosclerosis of the aorta and coronary arteries. On an emergency basis, the patient underwent coronary angiography, pronounced atherosclerotic changes in the coronary arteries were revealed: acute occlusion of the anterior interventricular artery in the middle third, stenosis of the diagonal branch up to 70% in the orifice, stenosis of the circumflex branch up to 70% in the middle third, extended stenosis up to 79% in the middle third of the right coronary artery.

Results The patient underwent percutaneous coronary intervention (pci) on a symptom-dependent artery: mechanical recanalization and stenting of the anterior descending artery (ada) by a drug-eluting stent.

Conclusion An increase in the incidence of acute coronary syndrome in pregnant women and postpartum women requires the development of an algorithm for additional examination of late reproductive age patients at the stage of pregnancy planning, in case of identification of possible risk factors for the development of cardiovascular diseases — observation of a cardiologist during pregnancy and in the postpartum period.

The aspect of injuring bile ducts during laparoscopic cholecystectomy is still of current concern. Causes of this complication include insufficient experience of surgical team, poor knowledge of topographic anatomy of subhepatic space, particularly when perivesical inflammatory infiltrate presents, inadequate approach conversion and so on. Most of patients with bile duct injuries undergo repeated operation in the same surgical unit where cholecystectomy was performed. In many cases, this results in a shortening of the segment of the common hepatic duct, which is favorable for restoration. Subsequent reconstructive surgery is usually performed in the worse conditions with a high risk of complications such as failure of sutures, biliary fistula, anastomotic stricture, etc. Most specialists recommend to abstain from primary reconstruction of the biliary tree in hospitals with no proper experience in hepatobiliary surgery and to perform only the external drainage of subhepatic space with subsequent admission of patient to a specialized clinic. We report a case of a young woman who suffered an excision of hepaticocholedochus fragment during laparoscopic cholecystectomy. A primary reconstructive surgery (hepatico-hepaticoanastomosis) was performed in the same clinic and resulted in external fistula of the common hepatic duct. The subsequent operation (hepaticoejunostomy) was performed in a specialized department of the regional clinical hospital. The woman underwent right-sided hypochondrium laparotomy with debridement of postoperative scar tissues. The stumps of common bile duct were mobilized in compact inflammatory infiltrate. The operation ended with distal stump closure and hepaticoenteroanastomosis formation. The patient was discharged with recovery. Six months later, her condition was satisfactory, and she was engaged in occupational activity.

This article considers a rare case of rupture of abdominal aortic aneurysm with thrombosed aorto-caval fistula formation, with thrombosis of the inferior vena cava and iliac veins. During the multiphase computed tomography, early enhancement of inferior vena cava was not obtained, but non-contrasting aorto-caval fistula was revealed in the venous contrast phase, as well as the absence of the contrast in the adjacent parts of the inferior vena cava and iliac veins. The patient was successfully operated and the diagnosis was confirmed intraoperatively.
