Aberrant Bronchial Artery to Non-Sequestrated Left Upper Lobe in Massive Hemoptysis.

Systemic arterial supply from the descending thoracic aorta to the basal segment of the left lower lobe without a pulmonary arterial supply is a rare congenital anomaly within the spectrum of sequestration lung disease. The most common pattern of anomalous systemic artery to the lung arises from the descending thoracic aorta and feeds the basal segments of the left lower lobe. We report an extremely rare case of a 29-year-old woman who underwent a successful left upper lobectomy for the treatment of recurrent massive hemoptysis from anomalous bronchial arterial supply to the lingular segment of left upper lobe.
