[A case of systemic origin of an aberrant artery to the basal segment of the lung]

Abstract

We report on a rare case of systemic origin of an aberrant artery to the basal segment of the lung (Pryce I type intralobar pulmonary sequestration) that caused occasional bloody sputum. The patient was admitted to our hospital after an abnormal image was discovered in Chest X-ray film. The chest MRI showed an abnormal vessel originating from the descending aorta. The aortagram showed an abnormal artery originating from the descending aorta and entering the left lower lobe, and the left pulmonary angiogram revealed a poorly blood supply to the left basal segments. The preoperative diagnosis of systemic origin of an aberrant artery to the basal segment of the lung was given. The patient was subjected to surgical treatment. During surgery, it was found that the abnormal artery, 12 mm in diameter, which was connected from the descending aorta to the left basal segments. The abnormal artery was dissected, and the left basal segments was removed. The postoperative course was uneventful.
