Elevated right atrial (RA) pressure reflects RV overload in PAH and is an established risk factor for mortality. Membranous IVC Obstruction Presenting with Antegrade/Retrograde Respiratory Flow in the Intrahepatic Segment in Doppler Imaging and Prostatic and Urethral Congestion The causes for portal hypertension are classified as originating in the portal venous system before it reaches the liver ( prehepatic causes), within the liver ( intrahepatic) or between the liver and the heart (post-hepatic).

An IVC diameter greater than 20 mm is commonly regarded as an upper limit of normal, which is a noninvasive indication of increased RA pressure in patients with cardiac or renal disease [4]. Increase in hepatic arterial flow in response to reduced portal flow (hepatic arterial buffer response) has been demonstrated experimentally and surgically. Caput Medusae: Symptoms, Causes, Diagnosis, and Treatment - Healthline Insufficient venous drainage may result from focal or diffuse obstruction or from right-sided heart failure, as in congestive hepatopathy Congestive Hepatopathy Congestive hepatopathy is diffuse venous congestion within the liver that results from right-sided heart failure (usually due to a cardiomyopathy, tricuspid regurgitation, mitral insufficiency read more .
