Management of a Pulmonary Sequestration With a Large Aberrant Artery Using a Hybrid Approach: Thoracic Endovascular Aortic Repair Followed by Video-Assisted Thoracoscopic Lobectomy.

Pulmonary sequestration is a rare congenital malformation of the lower respiratory tract, characterized by nonfunctioning lung tissue without tracheobronchial communication and receiving its blood supply from the systemic circulation. It can present as either intralobar or extralobar sequestration, with intralobar being more common. Surgical resection remains the treatment of choice, although preoperative strategies such as endovascular occlusion can reduce the risk of intraoperative complications. We report the case of a 52-year-old woman with a history of recurrent pulmonary infections who was referred for evaluation of an incidentally discovered cystic lesion in the left lower lobe following a transient episode of amaurosis fugax. Chest CT revealed a 5.3 cm pulmonary sequestration supplied by a large aberrant artery (AA) originating from the descending aorta. A two-stage hybrid procedure was performed, starting with thoracic endovascular aortic repair (TEVAR) to exclude the AA, followed by video-assisted thoracoscopic surgery (VATS) left lower lobectomy. The patient had an uneventful recovery and was discharged postoperatively. TEVAR was employed as a preoperative strategy to minimize the bleeding risks associated with the large AA during minimally invasive lobectomy. A hybrid two-stage approach using TEVAR followed by VATS is a safe and effective method for managing intralobar pulmonary sequestration with large aberrant vessels. Careful preoperative planning and a multidisciplinary approach are essential for optimal outcomes.
