Abstract:
Objective To probe the value of absent or reversed diastolic flow in hepatic artery shown by Doppler sonography of recently transplanted liver in predicting subsequent hepatic artery thrombosis.Methods The records of 54 liver transplantations performed were retrospectively reviewed.The first Doppler study of every case was done within 24 h after transplantation and subsequently reviewed.Findings were categoried into one of three patterns: forward flow,no flow and reversed flow throughout diastole.Meantime,the flow status of portal vein of every case was studied by Doppler sonography.Results Of 54 liver transplants, 12 had aberrant diastolic flow in the hepatic artery after liver transplantation.Four had reversed flow and 8 showed no flow in diastole.In this group of 12 transplants,hepatic artery thrombosis was not developed.Conclusions Reversed or absent diastolic flow in hepatic artery of a recently transplanted liver has no correlation with subsequent hepatic artery thrombosis.
