AimTo compare the efficacy of cesarean section (CS) combined with intermittent aortic balloon occlusion with that of CS alone for treating patients with placenta previa complicated by placenta accreta.MethodsForty-five patients with placenta previa complicated by placenta accreta who underwent CS were retrospectively studied. Twenty-two patients had undergone CS combined with intermittent aortic balloon occlusion (combination group) and 23 patients received conventional hemostatic support only (control group). The postpartum hemorrhage, transfusion requirements, operation time and recovery time, and the ability to preserve the uterus and fertility were analyzed.ResultsIntermittent aortic balloon occlusion significantly decreased the volume of blood loss in the combination group relative to the control group (597 ± 359 mL vs 2687 ± 575 mL; P < 0.001), and transfusion requirements were also reduced (498 ±195 mL vs 2390 ±789 mL; P <0.001). We observed shorter operation time in the combination group relative to the control group (63.8 ± 12.3 min vs 118.8 ± 22.4 min; P < 0.001), and fewer patients required uterine cavity stuffing followed by uterine artery embolization (n = 2 vs n = 10; P <0.05), uterine artery ligation (n = 1 vs n = 9; P < 0.05), and hysterectomy (n = 0 vs n =7; P < 0.05).ConclusionIntermittent aortic balloon occlusion may control postpartum hemorrhage in pregnancies complicated by placenta accreta, and improve the postoperative conditions.© 2018 Japan Society of Obstetrics and Gynecology.
