Isolated endovascular repair of anomalous systemic arterial supply to the left basal lung.

Anomalous systemic arterial supply to the left basal lung is a rare congenital lung malformation, and its optimal treatment strategy is not well defined. We present a case of a 61-year-old man who underwent thoracic endovascular aortic repair (TEVAR) for anomalous systemic arterial supply to the left basal lung complicated with aneurysmal dilatation of the aberrant feeding artery. Computed tomography angiography after TEVAR revealed significant shrinkage of the aneurysmal portion as well as complete occlusion of the aberrant feeding artery. TEVAR proved to be a safe and efficient treatment for this rare arterial abnormality.
