A case of rare development of arteriovenous malformation of the lower lobe of the right lung

Abstract

Arteriovenous malformations are one of the variants of congenital vascular malformations resulting from a defect in the development of the arterial and venous systems with the formation of direct messages between vessels of different diameters and shunting of blood with high velocity characteristics from the arterial to the venous part of the vascular system. Arteriovenous malformations are characterized by a wide variety of clinical manifestations and in some cases may be accompanied by severe circulatory disorders. Arteriovenous lung malformation (AVML) accounts for a small fraction of the AVM structure. The defect consists in the presence of arteriovenous anastomoses at the level of segmental, subsegmental and smaller vascular divisions. This article presents a case of detection of a rare malformation of arteriovenous malformation of the lower lobe of the right lung.
