2023年1月2日 · 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 ...

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.

Temporary vascular shunting is a surgical procedure used to rapidly restore blood flow to an area of the body when there is an injury or obstruction in a blood vessel. This technique involves inserting a temporary conduit, called a shunt, into the blood vessel to bypass the damaged or blocked segment.

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.

2011年3月1日 · 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.

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.

2021年4月1日 · Vascular shunt use was associated with lower rates of amputation during the early phase of care and should be a part of a more aggressive approach to restoration of perfusion in the most injured patients and most injured ischemic limbs.

The vascular shunt mechanism begins at the Vasomotor Control Centre (VCC). The VCC controls blood pressure and is located in the Medulla Oblongata. The VCC stimulates the Sympathetic Nervous System to redistribute the blood carried along the vessels to all parts of the body.

2024年3月26日 · Cardiovascular (cardiac) shunts are abnormal connections between the pulmonary and systemic circulations. Most commonly they are the result of congenital heart disease.

2020年9月4日 · There are a number of commercially available vascular shunts. Improvised shunts can be constructed out of any plastic tubing that has the adequate diameter to match the corresponding vessel, such as chest tubes, intravenous tubing, and feeding tubes.
