Hepatopulmonary syndrome, the clinical triad!

Liver cirrhoisis, hypoxia (hypoxemia) and Platypnea-Orthodeoxia. Learn what is the reason behind the nomenclature... Pulmonary arteriovenous malformations are found in patients with liver cirrhosis, probably due to the absence of a hepatic factor. 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. Ventilation perfusion mismatch will occur (Shunt Physiology) Diagnose the disease with Contrast ultrasound or technicium albumin. Contrast ultrasound is more accurate, so it is used as a confirmatory test.
