Thoracoscopic Segmentectomy for Extralobar Sequestration with Atypical Incomplete Fissures

Abstract

Abstract Introduction: Pulmonary sequestration is a rare congenital developmental malformation of the lung. It represents a piece of nonfunctioning aberrant lung tissue, with its own blood supply arising from the systemic circulation.1 Intralobar sequestration is more common, comprising about 75% of the cases, and is usually treated by lobectomy. Extralobar sequestration is less common (25%) and usually has its visceral pleura. Segmentectomy is the procedure of choice.2 We hereby present a patient with extralobar sequestration but with associated atypical incomplete fissures associated with adjacent normal pulmonary parenchyma. Materials and Methods: This is the 2-year-old boy who was found to have congenital pulmonary mass antenatally at an outside hospital. He had been asymptomatic. Chest CT, with angiography, showed a pulmonary mass in the left lower lung region, with systemic artery arising from the thoracic aorta. One should always look for blood supply arising from the abdominal aorta, which may pas...
