Two Cases of Pulmonary Sequestration Treated with Arterial Embolization / 소아알레르기및호흡기학회지

ABSTRACT

Pulmonary sequestration is a rare congenital mass of nonfunctional pulmonary tissue that lacks of a normal connection with the bronchial tree or pulmonary artery. It may be clinically asymptomatic but may be complicated by recurrent infection. The classical therapeutic approach is to resect the sequestration lobe to prevent infection. The arterial embolization of feeding artery is a new technique and a less invasive treatment than conventional surgical removal. We reviewed two patients with pulmonary sequestration whose complaints were persistent fever and cough or hemoptysis. They were diagnosed by computed tomography and aortography and treated with embolization of feeding arteries. They were sucessfully treated without any complication. We report two cases of pulmonary sequestration treated with arterial embolization instead of surgery.
