Pulmonary sequestration is a rare congenital anomaly with nonfunctioning lung tissue, for which the arterial blood supply is usually derived from the thoracic or abdominal aorta. Surgical resection is the conventional treatment for pulmonary sequestration. The arterial embolization of pulmonary sequestration is an alternative technique and a less invasive treatment than conventional surgical resection. Here, we report two infants with intralobar and extralobar types of pulmonary sequestration, successfully treated with coil embolization of the feeding artery without any complications.
