Anomalous Systemic Arterial Supply to Normal Basal Segments of Left Lower Lobe : A Report of Two Cases

폐격리 없이 좌하엽이 체순환 동맥으로부터 공급되는 기형적인 혈관 2예

Two cases of an anomalous systemic arterial supply to the basal segments of the left lower lobe without pulmonary sequestration are presented. In the first case, a preoperative diagnosis was made by chest CT, and confirmed by angiography, in a 22-year old man who had a recurrent hemoptysis. There was systemic arterial supply that originated from the thoracic descending aorta and no pulmonary arterial supply to the basilar segments of the left lower lobe. However, the pulmonary parenchyma was normal without sequestration. Ligation of the abnormal artery and a left lower lobectomy were performed without complications. In the second case, there were characteristic features of this anomaly on chest CT and the angiogram in a 31-year-old man with symptoms of hemoptysis. The patient refused surgery.

본 증례에서는 객혈을 주소로 내원한 두 환자에서 폐격리증의 소견이 없이 좌측 기저폐구역에 흉부 하행 대동맥에서 기인하는 기형적인 전신동맥의 혈액공급, 좌측 상폐구역을 제외한 하폐동맥의 결손과 함께 좌측 폐정맥을 거치어 좌심방으로 유입되는 혈관기형을 경험하였기에 보고 하는 바이다.
