Hepatopulmonary (hep-uh-toe-POOL-moe-nar-ee) syndrome is an uncommon condition that occurs in people with an existing liver disease that has advanced to the point it affects their lungs. People with hepatopulmonary syndrome have low blood oxygen levels (hypoxemia) caused by widespread dilation (expansion) of the lung blood vessels, both in size and number. The dilated vessels make it hard for the lungs to deliver an adequate supply of oxygen to the body. Liver transplant is the only cure for the syndrome.
