[Anomalous Systemic Arterialization of a Normal Basal Lung Segment with Aneurysm of the Aberrant Artery].
A 40-year-old woman was noted to have clubbing of the nails during an outpatient service for smoking cessation. Chest computed tomography showed an aneurysm of an aberrant artery running from the descending aorta to the left lower lobe. Hence, we diagnosed anomalous systemic arterialization of the lung. The proximal part of the aberrant artery measured 13 mm in diameter;moreover, it had developed an aneurysm(17 mm in diameter) in the lung parenchyma. The aberrant artery was ligated with a covering material (absorbable felt) and cut via a small access thoracotomy by a cardiovascular surgeon;subsequently, left lower lobectomy was performed. Pathological examination revealed significant atherosclerosis in the aberrant artery, demonstrating its severe fragility. To apply appropriate safety procedures and approaches are recommended when treating an aberrant artery to the lung, especially in the presence of an aneurysm.
