Pulmonary Sequestration

Abstract

PULMONARY sequestration is a congenital lesion in which a systemic artery supplies a cystic portion of the lung in which its bronchus usually does not communicate with the remainder of the bronchial tree. There are two types of sequestration recognized. Intralobar pulmonary sequestration is usually contained within the visceral pleura of a pulmonary lobe and its vasculature drains into the pulmonary venous system. Extralobar pulmonary sequestration is usually within a pleural sheath of its own and the venous drainage is to the azygos or hemiazygos system. The sequestrated portion of the lung is in both instances susceptible to infection. Seven new cases of pulmonary sequestration are presented. Report of Cases Case 1. —This patient was a 15-year-old Caucasian male who had a history of frequent colds and the production of mucopurulent sputum. He presented himself to the hospital with an acute upper respiratory illness, temperature 103 F
