WebHepatic artery flow is in the same direction as the portal vein (hepatopetal). The hepatic artery normally demonstrates a low-resistance waveform with continuous forward flow throughout the car-diac cycle (Fig. 6). The hepatic veins (HVs) drain blood from the liver into the inferior vena cava. The normal Doppler waveform obtained from the HVs ... WebObjectives: To determine the significance of spectral Doppler hepatic artery waveforms obtained in the first 10 days after primary liver transplantation and to determine the best early predictor of hepatic arterial thrombosis (HAT). Subjects and methods: A total of 645 patients were retrospectively followed up to 1 year after liver transplantation.
