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. Web29 de abr. de 2013 · McNaughton et al 12 describes the normal hepatic arterial waveform in the hepatic artery to be pulsatile with low resistance. The peak height of the wave corresponds to the peak systolic velocity ( V 1 ), and the trough to end-diastolic velocity ( V 2 ) The normal resistive index (RI) within the hepatic artery ranges from 0.55 to 0.8.
