Intralobar pulmonary sequestration supplied by multiple anomalous arteries: Report of a case

Pulmonary sequestration is abnormal pulmonary tissue that has separated fro m the normal pulmonary parenchyma, is not connected to the tracheobronchial tree, and is supplied by a systemic artery. We describe herein a case of i ntralobar pulmonary sequestration found in a 66-year-old man who was admitt ed to our hospital with hemoptysis, coughing, and fever. Angiography showed that the branches of the 11th left intercostal artery and a bronchial arte ry had formed a hypervascular area in the lower part of the left lung. Bron chial artery embolization and subsequent embolization of the left 11th inte rcostal artery were performed in an attempt to control the recurrent hemopt ysis. These treatments were unsuccessful, and he was transferred to our dep artment of surgery after coughing up about 400 ml of fresh blood. A left lo wer lobectomy was performed. The resected lung contained a large feeding ar tery, some acute and partly organizing inflammatory lesions within collapse d lung parenchyma, and massive intra-alveolar hemorrhage in the peripheral area. The patient had an uneventful recovery and was discharged 22 days aft er his operation.
