WebMay 1, 2008 · In addition, the waveforms may be affected by age- and development-related hemodynamic differences. For example, adults tend to have higher flow velocities, whereas neonates, particularly those born prematurely, have higher resistance to flow, especially in the cerebral and renal vascular beds. Web1 INTRODUCTION. Estimating right atrial pressure (RAP) is clinically important for diagnosing right-sided congestive heart failure (R-CHF), managing various hemodynamic conditions, and estimating pulmonary artery pressure. 1-3 Ultrasonographic measures of the caudal vena cava and the presence of hepatic venous distension are common …

WebAs liver cirrhosis continues, it may alter the hepatic vascular parameters; thus, the Doppler ultrasound scan Table 1 The percentage of hepatic artery and the portal vein velocity thresholds in our patient population No. % Hepatic artery velocity Decreased (< 30 cm/s) 2 2.0% Normal (30–60 cm/s) 28 28.0% Increased (> 60 cm/s) 70 70.0% Webdiastolic velocity of the hepatic artery were signifi- cantly larger than those in normal arteries (p < 0.01). During the recovery phase, these indexes of the hepatic artery … WebColor Doppler flow images of the hepatic artery were identified in 14 of 15 (93%) control subjects. The Doppler waveform of the hepatic artery characteristically has two phases. The large peak velocity is the systolic phase, whereas the tail represents diastolic velocity. The peak-systolic and end-diastolic velocities ranged from 36 bnw food
