Complex, Isolated Pulmonary Arteriovenous Malformation in Two Children With Severe Cyanosis.

Abstract

We present two cases of Isolated complex pulmonary arteriovenous malformations in two children presenting with cyanosis and exercise intolerance. We present the anatomical features and the management of each case. One patient was treated with surgical ligation of the draining vein, and one patient was treated percutaneously by closure of the feeding segmental artery.
