WebJul 8, 2009 · However, hepatic artery flow remains normal in most patients. Abnormal hepatic vein flow profiles are seen in patients with cirrhosis, but dampening or flattening of the flow profile has a multifactorial origin (Budd-Chiari, metastases, ascites) and can be observed in healthy subjects. WebMay 1, 2024 · It is very important to differentiate IVC from the aorta to avoid errors in interpretation. Always trace the IVC superiorly and make sure it is joining the right atrium. Also, try to look for the hepatic vein-IVC confluence when possible. Following table summarizes other key differences between these two vessels.

We observed an independent association with … WebFeb 5, 2024 · Thus, the normal flow in the hepatic veins is pulsatile. It usually consists of two antegrade (below the baseline in this case) waves: a larger systolic (S) wave and a smaller diastolic (D) wave (corresponding to x and y descents of the CVP waveform); And two retrograde waves (A and V) (corresponding to A and V waves of the CVP waveform) …
