Application of temporary ballon occlusion of the abdominal aorta in patients with pernicious placenta previa and placenta accrete

Abstract

Objective To explore the influence on intraoperative hemorrhage and relative complications of temporary balloon occlusion of the abdominal aorta in cesarean section for the pernicious placenta previa and placenta accreta. Methods One hundred and thirty-four cases of pernicious placenta previa and placenta accrete from January 2011 to January 2016 were analyzed retrospectively. Before the cesareans, temporary balloon occlusion in abdominal aorta was carried out in 69 patients (observation group). The other 65 patients didn't get the balloon occlusion in abdominal aorta (control group). The situation during and after the operation and relative complications were compared. Results The operation duration [(65.2±6.3)min vs (93.2±8.8)min], postpartum hemorrhage [(923.2±188.6)ml vs (2 791.8±336.2)ml], intraoperative blood transfusion [(423.7±59.3)ml vs (1 581.6±68.3)ml], the prothrombin time during the operation [(9.3±1.1)s vs (12.4±1.5)s], the hysterectomy rate[0 vs 7.7% (5/65)], hospitalization time [(5.2±0.9)d vs (6.8±1.1)d], and the rate of transferring to intensive care unit [1.4% (1/69) vs 12.3% (8/65)] in the observation group were lower than control group, with a statistical significant difference (P 0.05). Conclusions Temporary balloon occlusion of the abdominal aorta in cesarean section is a safe and effective technique, which can reduce the relative complications, such as the volume of bleeding and the risk of hysterectomy.
