Intralobar Pulmonary Sequestration With Aneurysmal Feeding Vessel: Use of Hybrid Surgical Management

We describe the endovascular exclusion and surgical resection of an intralobar pulmonary sequestration supplied by an aneurysmal feeding vessel from the aorta. Pulmonary sequestration is a rare congenital anomaly, and the presence of an aneurysmal feeding vessel is even rarer. The possibility of life-threatening hemorrhage resulting from failure to control these aberrant vessels has led many to pursue preoperative embolization. The anatomy in the patient described here was not deemed suitable for embolization, and we thus elected to pursue a novel approach. This case also demonstrates the diagnostic utility of magnetic resonance imaging for delineating the vasculature of pulmonary sequestrations when contrast-enhanced computed tomography is contraindicated.
