Abstract: Objective To explore the clinical usage of allograft vessels for portal venous reconstruction during radical resection for pancreatic cancer.Methods We retrospectively analyzed clinical data of 14 patients who underwent pancreaticoduodenectomy with vascular resection (PDVR) and reconstruction by allograft vascular form June 2009 to May 2013.Results Patient's mean age was (59.1 ±10.4) years old.The mean diameter of tumors was (3.9 ± 1.3) cm,mean lcngth of resected vessels was (4.4 ±0.5)cm,and the R0 resection rate was 71.4％.The implanted vessels in 4 cases were allograft portal veins,and in the other 10 cases were allograft iliac arteries.In morphological classification,9 cases used straight vessels and 5 cases used Y shaped vessels.The overall median survival time of the group was (14.0 ± 3.0) months.The 1,2 year' s survival rate was 52.0％ and 40.0％,respectively.Conclusions Allograft vessels for portal venous reconstruction during PDVR have biological and structural advantages.
