Abstract

We assessed the usefulness of routine Doppler ultrasonography for early detection of hepatic artery thrombosis after orthotopic liver transplantation and repercussions in patient prognosis. Seventeen confirmed cases of early hepatic artery thrombosis initially diagnosed by Doppler ultrasonography (10 of them before clinical indication) were reviewed. All patients underwent Doppler ultrasonographic studies in the first 3 days after orthotopic liver transplantation. Twelve cases of hepatic artery thrombosis (70.6%) were detected by this early Doppler ultrasonography. All 10 unsuspected cases of hepatic artery thrombosis and 5 of the 7 cases diagnosed after clinical indication were treated by revascularization. Grafts were salvaged in 80% of asymptomatic patients and in 42.8% of symptomatic patients. Furthermore, biliary complications were less serious in the first group. In conclusion, Doppler ultrasonography performed routinely in the first 3 days after orthotopic liver transplantation may permit early detection of hepatic artery thrombosis, even before clinical indications. This allows hepatic artery repermeabilization before liver function damage, improving graft rescue and patient prognosis.
