摘　　要：目的：探讨临时性球囊置入髂总动脉在凶险性前置胎盘伴胎盘植入剖宫产术中的临床应用。方法回顾分析5例经超声或 MR 检查诊断为凶险性前置胎盘合并胎盘植入患者,其中1例为 Rh（-）血型患者。剖宫产术前预置临时球囊于双侧髂总动脉,数字减影血管造影（DSA）明确球囊导管位置后,固定导管送产科手术室,术中待胎儿娩出后迅速充盈球囊,剖宫产术后6~8 h拔除球囊导管。观察并记录失血量、输血量、子宫切除率、接受 X 射线照射时间及剂量。结果5例临时性球囊置入髂总动脉均获得成功。出血量〈500 mL 者1例,500~1000 mL 者4例。1例因胎盘组织植入过深达浆膜层,穿透性胎盘,短时间内出血较为凶猛,行子宫次全切除术。其余4例保留子宫。结论剖宫产术前髂总动脉置入临时球囊能够减少剖宫产术中失血量、输血量,且能降低因术中不可控制的出血而继发子宫切除的风险。Objective To investigate the clinical application of temporary balloon occlusion of the common iliac artery in performing cesarean section for patients with pernicious placenta previa and placenta accreta.Methods A total of five cases with ultrasound or MRI diagnosed pernicious placenta previa and placenta accreta were analyzed retrospectively.One of the cases was diagnosed Rh（-）blood type.Prophylactic temporary balloon implantation in bilateral common iliac arteries were carried out before cesarean section.Digital subtraction angiography ensured the position of balloon catheter and the catheter was fixed.The balloon was inflated immediately after the removal of the fetus.The balloon was removed at 6-8 hours after the cesarean section.The amount of blood loss,transfusion requirement,cesarean hysterectomy rate, and X-ray exposured time and dose during the procedure were recorded.Results Temporary balloon implantation in bilateral common iliac arteries in all five patients were obtained successfully.The blood loss was seen 〈500 mL in one patient and 500-1 000 mL in other four patients.Because of placenta implantation over depth of serosa and placenta percreta in one case,massive intractable hemorrhage occurred in short time,partial hysterectomy had to be carried out.The uterus was retained in other four cases.Conclusion The temporary balloon occlusion of the common iliac artery in performing cesarean section is a safe and effective technique,and it can reduce the amount of blood loss,transfusion requirement and secondary risk due to uncontrollable bleeding during surgery.
