目的：探讨肢体软组织肉瘤及受累的大血管切除联合人工血管重建的临床疗效。方法对19例累及肢体重要血管的软组织肉瘤患者行肿瘤屏障切除联合人工血管手术，8例同时重建动脉和静脉，4例重建动脉，7例重建静脉，均采用人工血管置换。观察术后血管通畅及肿瘤复发情况。结果无1例出现重建血管感染，伤口均一期愈合。全部患者随访3～32个月，平均18个月。随访期间重建动、静脉通畅率分别为100％和46％，未见肿瘤复发。结论肢体软组织肉瘤累及重要血管进行切除联合人工血管重建安全可靠，能提高切除率，降低肿瘤复发率。%Objective To explore the clinical efficacy of major vascular resection and vascular prosthesis in the major vessels invaded by soft tissue sarcomas of extremity .Methods 19 patients with extremity soft tissue sarcomas invading major ves-sels underwent tumor resection and artificial vascular implantation .8 patients received combined reconstruction of arteries and veins,4 patients received artery reconstruction ,and 7 patients received venous reconstruction ,all using artificial vascular replace-ment .The vascular patency and tumor recurrence were observed after operation .Results None of the patients had revasculariza-tion infection and the wound all healed .19 patients were followed up for 3-32 months,and the average was 18 months.The arteries patency rate was 100%and the vessels patency rate was 46%,no tumor recurrence was found .Conclusion For the extremity soft tissue sarcoma patients with major vessels involvement ,tumor resection with artificial vessel implantation is safe and effective, and it can reduce recurrence and improve the tumor resection rate .
