FAQs

Can you live without a portal vein?

When the portal vein is absent, toxic metabolites such as ammonia and bile acids collected from the gastrointestinal tract have to bypass the liver directly drainage into the systemic circulation, thus may initiate hepatic encephalopathy.

What happens if portal vein is blocked?

Portal vein thrombosis is blockage or narrowing of the portal vein (the blood vessel that brings blood to the liver from the intestines) by a blood clot. Most people have no symptoms, but in some people, fluid accumulates in the abdomen, the spleen enlarges, and/or severe bleeding occurs in the esophagus.

Is portal vein thrombosis life threatening?

Portal vein thrombosis (PVT) is frequent in patients with liver cirrhosis and possible severe complications such as mesenteric ischemia are rare, but can be life-threatening.

Can the portal vein be replaced?

We developed a new method of portal vein replacement using the excised hepatic vein. This technique can be applied in major liver resections for tumors infiltrating the portal vein that have a safe distance from the hepatic vein.
