肺分画症11例に対する手術治療

Study of 11 Cases of Surgical Treatment for Pulmonary Sequestration

肺分画症は1946年にPryceにより命名された疾患である1）．肺組織の一部が正常肺から隔離され，体循環系より分岐した異常動脈から血液供給を受ける肺自体の発生異常である2）．近年，CTなどの画像診断の進歩に伴い肺分画症の術前診断は比較的容易となってきた3）．

Pulmonary sequestration was first described by Pryce in 1946. It is a developmental abnormality of the lung, in which a portion of lung tissue is isolated from the normal lung and receives blood supply from an anomalous artery branching off the body’s circulatory system. In recent years, advances in diagnostic imaging, particularly computed tomography （CT）, have made the preoperative diagnosis of pulmonary sequestration more straightforward. Thoracoscopic surgery has increasingly been used for treatment；however, there is still no definitive evidence regarding the extent of resection or the use of automatic suturing devices for the dissection of abnormal arteries. In this report, we summarize the cases of pulmonary sequestration treated surgically at our hospital and discuss the clinical presentation and surgical techniques.
