Video assisted thoracic surgery sublobar resection of intralobar pulmonary sequestration after preoperative embolization of systemic blood supply

Abstract

Intralobar pulmonary sequestration is abnormal lung tissue of embryonic origin that receives arterial blood supply from the systemic arterial circulation from the abdominal aorta. The arterial blood supply traverses the diaphragm and courses through the inferior pulmonary ligament. Intralobar pulmonary sequestrations are usually treated by anatomic lobar or sublobar resections via an open thoracotomy. Recent reports suggest the utility of a video assisted thoracic surgery (VATS) pulmonary resection. However, the presence of the feeding systemic artery often makes VATS resection difficult or impossible, due to the risk of injury to the feeding vessel, and subsequent retraction below the diaphragm. We present procedural video recordings describing a multidisciplinary procedure, where precedent coil embolization of the feeding systemic vessel allows for relative risk-free VATS sublobar resection of the intralobar pulmonary sequestration.
