Pulmonary arteriovenous malformation treatment

Abstract

Pulmonary arteriovenous malformations (PAVMs) are abnormal direct communications between a pulmonary artery and pulmonary vein. PAVMs can be simple (consist of a single feeding vessel and a nonseptated aneurysmal sac with a single draining vein) or complex type (consist of multiple feeding arteries, multiple draining veins, and septated arteriovenous connections).Complex PAVMs constitute approximately 10 % of these lesions.
