So, liver Cirrhosis will affect the blood vessels in the lungs by 2 different mechanisms:- 1) Absence of a hepatic factor which leads to arteriovenous malformatins in the lung. 2) Production of Nitric Oxide (NO) which is vasodilatory in effect, which will dilate the arteriovenous shunts in the lungs, increasing the chance of blood passing quickly without sufficient gas exchange, which furtherly worsens the problem.
