Anesthetic Considerations for a Patient with Intralobar Pulmonary Sequestration Supplied by an Aberrant Aneurysmal Branch

Pulmonary sequestration is a congenital malformation of the lower respiratory tract characterized as embryonic lung tissue often supplied by an aberrant branch of the descending aorta [1]. Pulmonary sequestration is believed to encompass 0.15-6.45% of all congenital pulmonary malformations, making it extremely rare [2, 3]. While numerous case reports of pulmonary sequestration have been published, most describe the presence of an aberrant artery extending into the pulmonary vasculature [2]. We present a case of a 41-year-old male with intralobar pulmonary sequestration of his right lower lobe, supplied by an aneurysmal branch of the thoracic aorta , undergoing a right thoracotomy, aneurysm resection, and right lower lobectomy.
