Pulmomary Sequestrtion 2례 보고

Abstract

The pulmonary sequestration is rare congenital anomaly characterized by the presence of part of lung tissue which is supplied by an aberrant artery from the aorta or its branch and usually has no communication with the normal bronchial tree.

It was first presented by Huber in 1777 and described in details by Pryce in 1946. There are two types of sequestration recognized. One is intra-lobar pulmonary sequestration which is usually contained within the visceral pleura of a pulmonary lobe. The other is extralobar pulmonary sequestration which is usually within a pleural sheath of its own. We present two cases of intra-lobar pulmonary sequestration experienced in 1983 and in 1984.
