Systemic Arterial Supply to the Basal Part of the Right Lung without Sequestration: Treatment by Coil Embolization

Systemic arterial supply to the base of the lung without sequestration is a rare congenital anomaly. In this entity, the anomalous artery arises from the aorta with no bronchial structural defect. Most of the patients are asymptomatic but few may present with hemoptysis or sometimes in severe cases with left-sided heart failure. The treatment of choice is usually a surgical resection of the affected portion of the lung, especially when pulmonary artery (PA) supply is ab-sent. However, transarterial embolization (TAE) has been recently considered especially in cases where the lung base has normal PA anatomy.
