Extralobar Pulmonary Sequestration With Anomalous Blood Supply From The Subclavian Artery

Abstract

Pulmonary sequestration is a rare embryonic mass of lung tissue that has no identifiable bronchial communication and that receives its blood supply from one or more anomalous systemic arteries. Systemic blood supply is commonly from the thoracic aorta. Venous drainage is commonly to systemic pulmonary vessels. A healthy, asymptomatic 20 year-old male was admitted to our hospital for evaluation of a left sided mass. The standard chest roentgenograms, a contrast-enhanced chest tomography, a bronchoscopic examination, thoracic magnetic resonance imaging and a selective angiography were performed. With these findings we decided that this heterogeneous lesion between mediastinum and left upper lobe as extralobar pulmonary sequestration. The patient underwent left sided posterolateral thoracotomy. We performed sequestrectomy. Postoperative period was uneventful.
