title: Preoperative embolization of aberrant systemic artery in sequestration of lung.
abstract: A 40-year-old man presented with left lower lobe pneumonia that failed to resolve on antibiotic therapy. Computed tomography revealed intralobar sequestration of the left lower lobe supplied by a large artery from the descending aorta. The aberrant artery was embolized using polyvinyl alcohol particles. The sequestered tissue was resected 3 weeks later. Identification and control of the aberrant artery is essential to avoid inadvertent injury and massive hemorrhage.
