It wil mostly cause a failure of the transplantation. This case o hepatic artery thrombosis showed a stable clinical course and minimal histological change, and now has been survi ving for 4 years with normal liver function. We investigated the possible causes for asymptomatic hepatic artery throm bosis in one patient after orthotopic liver transplantation ( OLT) and discussed the diagnosis of ischemia of OLT pathologically and clinically. METHODS: Liver function test, color Doppler ultrasono graphy, and hepatic arteriography were performed during the development of hepatic arteriothrombosis. Possible fac- tors for the asymptomatic process of the thrombosis were analyzed. RESULTS: On the 4th postoperative day, thrombosis form ed at the anastomotic stoma of the hepatic artery, and on the 11th postoperative day, the artery was completely oc- cluded. Serial liver biopsies revealed intrahepatic cholesta- sis, hydropic degeneration of hepatocytes, atrophy of the biliary epithelium, and fibrosis in the portal area. Monitor- ing of liver function showed nothing abnormal except ele- vation of γ-GT and ALP levels. On the 71st day after OLT, arteriography demonstrated that the hepatic artery re- mained completely occluded in addition to the establish- ment of collateral circulation and compensation of the por- tal vein. The patient didn' t show any symptoms of arterial thrombosis. CONCLUSION: Collateral circulation and compensation o the portal vein are beneficial to allograft survival and avoidence of retransplantation after thrombosis of the he- patic artery. Color Doppler ultrasonography within 2 weeks after OLT is helpful to the early diagnosis of hepatic arterio- thrombosis.展开更多
