Objective:To explore the surgical techniques of hepatic arterial reconstruction in liver transplantation and the therapeutic selection of its early thrombosis. Methods:The clinical data of hepatic arterial reconstruction based on 159 cases of cadveric donor liver transplantation and 3 cases of livingrelated liver transplantation perfomred from April 2003 to March 2006 in the Eastern Hepatobiliary Surgery Hospital of Second Military Medical University were analyzed retrospectively.Anastomosis time was compared between two groups with different vascular calibers. Early hepatic arterial thrombosis (HAT) was treated by means of interventional thrombolysis. Results:Anastomosis for hepatic artery with less than 3mm in diameter （n＝42,average time 33.6±21.3 min ） exhausted significantly more time in comparison with those with more than 3mm in diameter（n＝120,average time 19.4±7.4min）.For 3 cases of livingrelated liver transplantation,anastomosis time was 89min,120min and 34min,respectively.Two cases (1.2%) were complicated with early HAT.One case was successfully treated by thrombolysis,but the other had to establish urgently a conduit between aorta and the graft following an attempting thrombolysis. Conclusion:It exists more difficulties in the reconstruction of hepatic artery with small caliber.It implicates that microsurgery should be applied for pediatric livingrelated liver transplantation.But adequate surgical techniques could diminish the incidence of postoperative HAT.Effective therapeutic procedure needs to be carefully chosen for individual early HAT.
