Abstract:
Objective:To evaluate the perioperative safety and long-term prognosis of allogeneic vein replacement in abdominal surgery.Methods:Clinical data of 115 patients receiving allogeneic vein replacement from Jan 2013 to Dec 2020 was retrospectively analyzed.Results:The most common operation was radical pancreatoduodenectomy for pancreatic cancer (75.7%), and the most common vascular replacement sites were the junction of portal vein system (53.9%), followed by superior mesenteric vein (23.5%) and portal vein (18.3%). In our group, 6 patients died (5.2%), 31 patients had complications (27.0%), and 2 patients had portal vein thrombosis (1.7%). During the follow-up period, 8 cases (7.5%) had mild stenosis, 12 cases (11.5%) had moderate stenosis and 14 cases (13.2%) had severe stenosis. The half-year, one-year and two-year incidence of moderate and severe stenosis were 8.0%, 24.4% and 34.5% respectively.Conclusions:The early and mid-term result of allogeneic vein replacement is satisfactory. Use of postoperative anticoagulation may help reduce the incidence of thrombogenesis or stenosis .
