Anomalous systemic arterial supply to normal basal segments of the left lower lobe. A report of two cases.
Two cases of anomalous systemic arterial supply to the basal segments of the lower lobe of the left lung without sequestration are presented. In the first case, the final diagnosis was made during a surgical operation, and lobectomy of the lower lobe of the left lung was performed. In the second case, the preoperative diagnosis made by CT was confirmed by angiography. An anastomosis was performed between the anomalous artery and the pulmonary artery without resection of the basal segments. Six months after surgery, pulmonary angiography showed improved flow of the anastomosed vessel, but little improvement was evidenced in the perfusion scan.
