Pulmonary arteriovenous malformations after cavopulmonary anastomosis

Abstract

Pulmonary arteriovenous malformation (PAVM) is common after cavopulmonary anastomosis. PAVMs appear on chest X-ray film as diffuse opacity in one or both lungs. Angiographically, it appears as spidery diffuse vascularity with near simultaneous opacification of pulmonary arteries and veins.
