摘要目的 探讨腹主动脉阻断球囊在骨盆肿瘤手术中的应用及其围手术期相关血管问题的处理.方法 回顾性分析2005年12月至2010年4月期间265例骨盆肿瘤患者的资料.在行骨盆肿瘤手术前运用Seldinger法行股动脉置管,在肾下腹主动脉内留置球囊导管,肿瘤切除过程中,球囊完全阻断肾动脉以下腹主动脉主干血供,术后撤除球囊导管,保留股动脉鞘管6h.结果 所有患者均成功应用腹主动脉阻断球囊,球囊阻断时间平均(66 ±4) min,未出现腹主动脉破裂和急性肾功能衰竭并发症.6例术后引流出血多,重新进手术窒进行术野造影诊断,其中3例行髂内动脉弹簧圈栓塞止血,1例行腰动脉弹簧圈栓塞止血,2例髂总动脉主干管壁破损出血,应用小覆膜支架封堵破口；6例术后出现穿刺侧股动脉血栓形成,1例出现双侧下肢动脉血栓形成,予以股动脉切开取栓恢复血运.2例出现股动脉穿刺点假性动脉瘤,予以缝合修补治疗,愈合良好. 结论 腹主动脉阻断球囊对于减少骨盆肿瘤手术出血是有效的,使用过程应规范.对于围手术期出血和动脉血栓形成应有认识,及时处理.

abstractsObjective To evaluate abdominal aortic balloon occlusion during pelvic tumors surgery and mamagement of related vascular complications. Methods We retrospectively analyze the clinical data of 265 pelvic tumor cases from December 2005 to April 2010.Before pelvic tumor operation,we place a sheath by Seldinger maneuvre in common femoral artery and send a balloon catheter in the abdominal aorta below the level of renal artery.The balloon catheter occluded the blood flow below the level of renal artery totally during the time of removing the tumors.After the procedure,we pull the balloon catheter out and normally retain the sheath for 6 hours. Results The procedure was successful in all cases and the average time of abdominal aorta blockade was (66 ± 4) min.There was no abdominal aortic rupture and acute renal dysfunction.Emergency angiography was performed on the operative region to diagnose the cause of massive bleeding after the open surgery in 6 cases.Among them,3 cases underwent embolization of internal iliac artery to stop bleeding and 1 case underwent embolization of lumber artery.Small covered stent was deployed in the common iliac artery to stop bleeding in 2 cases.Thrombosis of femoral artery at the puncture site occurred in 6 cases and bilateral thrombosis developed in 1 case. Blood flow was restowed to the femoral artery by open thrombectomy.Pseudoaneurysm formation around the puncture point occured in 2 cases and they underwent open surgical repair,then recovered well. Conclusions Balloon catheter occlusion of abdominal aorta is an effective method to control the hemorrhage in the pelvic tumors' operation.
