Pulmonary Sequestration Supplied by an Aberrant Infra-diapharagmatic Artery

Abstract

Hasan S Yamin and Amro Y Alastal

Sequestered lung is a discrete mass of lung tissue, where airways do not connect with the rest of the tracheabronchial tree, and that receives its blood supply from a systemic artery rather than a pulmonary one, while sometimes maintaining normal venous drainage to the heart. Abnormal feeding arteries have been reported from the thoracic and abdominal aorta, celiac trunk, coronaries among others. In this article we describe a patient with left lower lobe sequestration supplied by a peculiar infra-diaphragmatic artery.
