Abstract:
Objective To analyze the application effect of non-penetrating vascular closure system in portal vein reconstruction of allogenic liver transplantation in adults.
Methods Clinical data of 222 patients undergoing allogeneic liver transplantation were retrospectively analyzed. According to whether vascular closure system was used in portal vein reconstruction during operation, all patients were divided into vascular clip group (n=137) and traditional suture group (n=85). Perioperative conditions, clinical prognosis and complications were statistically compared between two groups.
Results All patients successfully completed the surgery. The success rate of one-time portal vein anastomosis was 93.4% (128/137) in the vascular clip group. A total of 14 patients died during perioperative period in this study with a mortality rate of 6.3% (14/222). No portal vein-related complications occurred during perioperative period in both groups. The time of portal vein anastomosis in the vascular clip group was (5.6±1.7) min, which was significantly shorter than (10.7±3.6) min in the traditional suture group (P < 0.05). The incidence and grade of perioperative complications did not significantly differ between two groups (all P > 0.05).
Conclusions It is safe and feasible to utilize vascular closure system to reconstruct the portal vein during liver transplantation. Compared with traditional suture, it can effectively shorten the time of portal vein anastomosis.
