The purpose of this pictorial review is to understand the embryological basis of the development of congenital hepatic vascular shunts and to review the multimodality imaging appearances of congenital and acquired hepatic vascular shunts.

This review is an effort to succinctly describe various vascular anomalies and conditions associated with hepatic shunts including congenital hepatic shunts, hereditary hemorrhagic telangiectasia (HHT), and hepatic hemangiomas.

A heart shunt is an irregular pattern of blood flow in your heart. Cardiac shunts vary widely. Some cause few to no symptoms, while others can be life-threatening.

Jan 2, 2023 · A liver shunt is an unnatural connection that develops between the portal vein and systemic veins. The shunt causes blood to bypass the liver partially or completely, causing complications. There are two types of liver shunts: Intrahepatic and extrahepatic. Intrahepatic shunts occur when the connection forms inside the liver, especially in ...

May 20, 2024 · Intrahepatic arterioportal shunts, also known as arterioportal fistulas, represent abnormal flow between the portal venous system and a hepatic arterial system within the liver. They can be a reversible cause of portal hypertension.

Jan 1, 2000 · Three types of intrahepatic shunts between the major vessels of the liver are possible: portosystemic venous (portal vein to hepatic vein or vena cava), arterioportal (hepatic artery to portal vein), and arteriosystemic (hepatic artery to hepatic vein). Visualization of these shunts on cross-sectional imaging is unusual.

Mar 1, 2011 · To propose a strategy for early diagnosis and management of intrahepatic vascular shunts (IHVSs). We systematically screened 3143 patients liable to develop IHVSs. Diagnosed patients were comprehensively evaluated using color Doppler and multiphasic CT.

May 5, 2019 · Hepatic arterioportal shunts (HAPS) occur due to organic or functional fistulization of blood flow between arterial hepatic vasculature and venous portal systems. It is a type of hemodynamic abnormality of the liver being observed increasingly with the use of temporal imaging modalities.

Apr 21, 2017 · Vascular shunts are illustrated, including portosystemic shunts (intra- and extrahepatic), arterioportal shunt, shunts of hereditary hemorrhagic telangiectasia, and acquired arteriovenous fistula. Familiarity with the pathogenesis and imaging features of these vascular entities can aid radiologic diagnoses and guide appropriate patient management.

Mar 26, 2024 · Cardiovascular (cardiac) shunts are abnormal connections between the pulmonary and systemic circulations. Most commonly they are the result of congenital heart disease.
