On the Issue of Optimizing Surgical Tactics and Blood-Saving Techniques in Case of Placenta Ingrowth Into the Uterine Scar

AIM OF STUDY The study of the results of delivery of pregnant women with placenta ingrowth in the uterine scar depending on the clinical status and the methods of blood saving.

MATERIAL AND METHODS The design of a selective retrospective study included 54 pregnant women with central placenta previa and uterine scar after caesarean section (CS), with histologically confirmed results of placenta accreta. Among blood-saving methods we used: ligation of three pairs of main vessels of the uterus, ligation of the internal iliac arteries, complex compression hemostasis according to R.G. Shmakov, temporary clamping of the common iliac arteries.

RESULTS CS with fundal incision was performed in 47 women (87.0%) out of 54. Hysterectomy was performed in 17 women (31.5%) out of 54. In the remaining 37 cases (68.5%), metroplasty and organ preservation were performed. There was no relaparotomy; there was no maternal mortality; perinatal mortality was 4 (7.4%); forced opening, bladder resection were performed in 7 (13.0%) cases; opening of the bladder without wall resection — in 2 (3.7%); 2 near miss cases; there were no complications associated with temporary clamping of the common iliac arteries; endometritis (recovery after conservative treatment) was revealed in 2 women (3.7%). Histologic examination results: 15 (27.8%) of placenta accreta, 30 (55.6%) of placenta increta, 8 (14.8%) of placenta percreta. In 8 cases, there was a combination of placenta increta into the uterine scar region of different depths, and in 2 (3.7%) cases, a combined deeply invasive lesion of the posterior wall of the lower segment and the body of the uterus.

CONCLUSION Complex compression hemostasis according to R.G. Shmakov is the most rational and promising method of blood saving, acceptable among the majority of patients with placenta accreta spectrum. Temporary clamping of the common iliac arteries is advisable in case of damage to the posterior wall of the bladder. Preservation of the uterus: in case of a deeply invasive lesion, including cases of combined damage to the posterior wall of the lower segment of the uterus or the body of the uterus, significant blood loss before the woman enters the hospital, it is not an imperative of surgical tactics.
