Objective To study the surgical treatment of major blood vessels invaded by tumors in order to raise the resection rate and postoperative survival rate. Methods Clinical data were analyzed on 26 patients undergoing (resection) of tumors along with reconstruction of major blood vessels from October 1998 to February 2004. Results Tweety-three cases were followed up for 2～65 months with median 42.8 months. Doppler ultrosonography and CTA examination were performed respectively during the follow-up process.In 5 patients with carcinoma of the head of pancreas who had inferior vein cava replaced and in 1 patient with cholangiocarcinoma who had portal vein replaced,3 were complicated with carcinoma embolism formation at 3,12 and 15 months respectively after surgery,(postoperative) graft patency was 50%;all of the 6 patients had recurrence of the tumor at 3,6,8,12,24 and 31 months respectively after surgery.Seven patients with tumor in pelvic cavity or in posterior space of peritoneum were followed up for about 2 years,1 of them had tumor recurrence ,but the graft kept patent,2 patients with sarcoma in the limbs were followed up for 1 year without tumor recurrence or vessel obstruction.Eleven patients with tumors in the neck were followed up for 3 months to 5 years without tumor recurrence or vessel obstruction. Conclusions (Combination) of resection of neoplasm and reconstruction of major blood vessels is safe,effective and practical method for patients with major wessels invaded by tumor.
