Symptoms usually result from abdominal distention. One is the hepatic artery, which brings in oxygen-rich blood from the heart. Conclusions: Measurements of respiratory variation in IVC collapse in healthy volunteers are equivalent at the level of the left renal vein and at 2 cm caudal to the hepatic vein inlet. There are several very important reasons to assess the IVC with echocardiography.
