Transarterial coil embolization in the treatment of systemic arterial supply to normal segment of the lung without sequestration

We report a case of systemic arterial supply to normal segment of the lung without sequestration in a 27-year-old man with intermittent and massive hemoptysis. Multidetector-row CT scan demonstrated that dilated basal pulmonary venous branches and an aberrant artery connecting lower thoracic aorta and running toward the medial basal segment of right lung. Angiography showed a dilated aberrant artery with mild shunts to basal pulmonary venous branches connecting an anomalous pulmonary vein. Transarterial embolization of the aberrant artery was occluded by multiple 0.035-in. coils under balloon occlusion technique. Hemoptysis has been ceased after transarterial coil embolization which is useful and safe in the treatment of this rare congenital anomaly and may be alternative to surgical intervention.
