腹膜后肿瘤术中重大血管的切除及重建

目的提高切除侵及腹部重大血管的腹膜后肿瘤的手术技能。方法总结近年来本院收治的腹膜后肿瘤中２５例侵及重大血管的手术切除及血管重建方面的经验。结果经过术前准备和术前评估,精心设计手术方案,对２５例患者成功实施了腹膜后肿瘤（包括受累血管）完整切除和相应的重大血管重建,无手术死亡病例。结论侵及重大血管的腹膜后肿瘤已不是手术禁忌证,应尽可能将受累血管及肿瘤完整切除,再行必要的血管重建,从而达到减少术后局部复发以及延长存活时间的目的。

Major blood vessel excision and reconstruction in the treatment of retroperitoneal neoplasms

Objective To summarize the experience in the treatment of retroperitoneal tumors involving major blood vessels. Methods Twenty five cases with retroperitoneal tumors involving major blood vessels were treated by excision of the tumor and the major blood vessel involved followed by vascular reconstruction. Results After a car eful preoperative evaluation and necessary preparation, the tumor together with the involved blood vessels in all patients are successfully resected and the severed major blood vessels reconstructed. There was no operative death. Conclusion Retroperitoneal neoplasm involving major blood vessels is not a contraindication for surgical resection. The tumor and the involved vessel can be removed en bloc followed by vascular reconstruction. The risk of local tumor recurrence can thus be minimized and better survival achieved.
