Evaluation of treatment results in patients after surgical hemostasis using CT-angiography

Objective: to evaluate the results of treatment of patients after undergoing surgical hemostasis in obstetric hypotonic bleeding. Materials and methods: the 31 patients were examined, whose delivery was complicated by hypotonic uterine bleeding, and as a result, surgical hemostasis was performed in the amount of ligation of the ovarian and internal iliac artery. Anthropometric data were analyzed, as well as the dynamics of the results of laboratory and instrumental research methods before and after surgery. In the late postoperative period, the results of helical computed tomography (CT) under angiography conditions were evaluated in the period from 6 months to 5 years. Statistical processing was carried out using the IBM SPSS Statistics 25 program. Results: the age, anamnestic data, anatomical and physiological parameters of patients, terms of delivery and their outcome did not become predictors of developed hypotonic bleeding. Early postpartum bleeding was determined in 93,5% of cases. Extirpation of the uterus was performed in 9,7% of cases. The median blood loss was 1200,0 ml, blood loss of 45-50% of the BCC was determined in 19,4%, 35–45% of the BCC was also in 19,4%. The reduced level of erythrocytes persisted until the moment of discharge, and the reduced hemoglobin after the operation tended to increase. In the course of CT, in 100% of cases, defects in the contrasting of the internal iliac artery on both sides were determined. Collateral circulation was also developed in 100,0% of cases, despite the type of defect in the internal iliac artery. Conclusions: ligation of the ovarian and internal iliac artery is a reliable method of surgical hemostasis, which allows saving the uterus in 90,3% of cases. In the late postoperative period, all patients developed various degrees of arterial patency in the ligation zone, and collateral circulation developed on both sides.
