Usefulness of interlocking detachable coil for embolization of the major aorto-pulmonary collateral artery: a case report.

A 5-yr-old male had undergone a right-modified Blalock-Taussig shunt operation at the age of 1 mo for stenotic patient ductus arteriosus and pulmonary atresia with ventricular septal defect. Before a corrective operation, the angiogram revealed one large major aorto-pulmonary collateral artery from the descending aorta to the right upper lung. Embolization of the major aorto-pulmonary collateral artery was successfully performed using interlocking detachable coils. This is the first reported case of embolization of the major aorto-pulmonary collateral artery using this device.
