Necessary resection of the left lower lobe due to systemic arterial supply

Symptomatic lung sequesters are usually treated with resection. Most often the aberrant arterial supply is ligated or reimplanted onto the pulmonary artery. Baek and colleagues 2 recently described a patient with anomalous arterial supply of a left basal segment of the lung in which mere ligation of the anomalous artery produced a satisfactory result. We present a similar case in which resection had to be performed despite our initial goal to preserve the entire lung.
