The clinical evaluation of internal iliac arteries balloon occlusion for placenta accreta spectrum

Abstract

Objectives: To evaluate the balloon occlusion of the internal iliac arteries during a caesarean section in the group of patients with placenta accreta spectrum. Material and methods: We analysed 29 pregnant women with placenta accreta spectrum. The study group consisted of 15 patients, who underwent a caesarean delivery with temporary bilateral internal iliac artery occlusion. In the control group, we examined 14 women who had a standard caesarean delivery without any radiologic procedure. We compared pre- and post-operative haemoglobin level, necessity of blood transfusion, intraoperative blood loss, intensive care requirement, complications, duration of surgery, anaesthesia and hospital stay. Results: The history and obstetric outcomes were similar in both groups. The study group required fewer blood transfusions than the control group (p = 0.0176). We administered less packed red blood cells and fresh frozen plasma. Complications were more frequent in the control group (p = 0.0014). Complications related to occlusion of the internal iliac arteries did not occur. The intensive care unit transfer was more frequent in the control group (p = 0.0329). The duration of surgery and hospital stay did not differ between groups. The anaesthesia time was longer in a study group, which related to the radiologic procedure. Conclusions: Caesarean delivery for placenta accreta spectrum with bilateral balloon occlusion of the internal iliac arteries requires fewer transfusions. It contributes to a decrease in the complication rate and maternal morbidity.
