Abstract: Objective To summarize the clinical experience in applying vascular surgical techniques to treat the tumors with the vital vessels invasion. Methods The clinical data of 30 patients with vital vessels involved by tumors who had been treated by vascular surgical techniques from Jan.2001 to Aug.2007 were analyzed retrospectively. Results Thirty patients were subjected to surgical procedures including artificial blood vessels replacement, patch plasty，tumor thrombectomy and so on.Twenty-seven cases(90%) experienced radical resections and 3 cases(10%) underwent palliative resections. Five cases(16.7%) died perioperatively.Twenty-five cases (83.3%) were followed up from 1 day to 57 months.Up to Aug.2007, 3 cases(10%) survived more than 48 months， 5 cases(16.7%) more than 36 months， 7 cases(23.3%) more than 24 months， 10 cases(33.3%) more than 12 months， 14 cases(43.7%) more than 6 months and 17 cases(56.7%) more than 3 months. Conclusion Surgical treatment of tumors invading the vital vessels by vascular surgical techniques could enhance the possibility of radical resection and operative safety.
