[Diagnosis and management for early hepatic artery thrombosis after liver transplantation]

To explore the diagnosis and management of early hepatic artery thrombosis (HAT) after liver transplantation.

Routine examination of Color Doppler Imagine (CDI) was used to detect hepatic artery flow after liver transplantation in 220 cases from April 2001 to November 2004. Suspected patients were further confirmed by immediate hepatic artery angiography, and continuous infusion of urokinase through hepatic artery with catheter was performed to the patients with HAT.

HAT was identified in 6 patients (2.7%), occurring 5.5 days (2 - 19 days) after liver transplantation. Hepatic artery recanalization was obtained in 6 cases. One patient died from lung infection 2 months after liver transplantation. One patient underwent the second liver transplantation because of the recurrence of HAT 6 months after the first transplantation, but died from multiple system organ failure 2 months after the operation. The other 4 cases have been surviving well disease-freely.

CDI is useful for the diagnosis of early HAT after liver transplantation. Contributes to recovery of the hepatic artery flow, continuous infusion of urokinase through hepatic artery with catheter may be the first choice of the therapy for early HAT.
