Intralobar Pulmonary Sequestration: Aortographic Demonstration

¹ Divisions of Pulmonary Medicine, Thoracic Surgery and Diagnostic Radiology, Montefiore Hospital and Medical Center and Morrisania City Hospital

Two cases of intralobar pulmonary sequestration are reported in which the pre-operative diagnosis was aided by selective aortography. In one, congenital esophagobronchial fistula was also present, the communication with the pulmonary sequestration being demonstrated preoperatively. The literature reveals seven of a total of more than 150 surgically treated patients with intrapulmonary sequestration in whom aortography was useful in the preoperative demonstration of an anomalous blood supply characterizing this type of malformation. The coexistence of congenital esophagobronchial fistula and pulmonary sequestration has been previously reported in four cases. There is reason to believe that pulmonary sequestration, whether intralobar or appearing as an accessory lung (extra-lobar sequestration) is due to disturbances in the normal cycle of embryogenesis.
