Objective To explore the application of magnetic-assisted fast major vascular reconstruction technique in liver transplantation. Methods The clinical data of liver transplant patients undergoing magneticassisted fast major vascular reconstruction and conventional suture reconstruction between November 2018 and December 2019 were retrospectively analyzed. Results A total of five patients were finally enrolled in magneticassisted Liver transplantation（LT）， whereas 172 patients underwent regular LT. The donor age， primary disease，as well as the warm and cold ischemia time were comparable between magnetic-assisted and regular LT groups （P ＞ 0.05）. In addition， the recipient age， sex， primary disease and preoperative Child-Pugh classification were not different， patients undergoing magnetic-assisted LT experienced an median anhepatic period of 10.3（ 9.5～13.2）min， which was significantly shorter versus 43.5（ 35.8～ 55.6） min of patients who underwent regular LT （P ＜ 0.001）. Of note， postoperative liver transaminase， as well as total bilirubin level were not significantly different at different time stages（ P＞ 0.05）. In addition， the incidence of vascular associated complications， such as hepatic artery， portal vein or IVC thrombosis， biliary stenosis， as well as acute renal dysfunction were all comparable between the two groups（ P＞ 0.05）. Conclusion Fast revascularization of the donor liver by using the novel magnetics is safe and feasible in LT.
