Abstract

Twenty-five patients (mean age 7.0 ± 4.8 years) underwent transcatheter coil occlusion of patent ductus arteriosus with detachable coils. The minimum diameter of the ductus arteriosus ranged from 1.0 to 4.2 mm (mean 2.6 ± 0.9 mm). A single-coil technique was used in 17 patients, double- (six patients) or triple-coil (two patients) techniques were used in eight patients. The coil was not detached until sufficient shape and position of implanted coils were confirmed. All patients had successful implantation of coils regardless of the morphologic characteristics of the ductus. Immediately after the occlusion, heart murmurs were abolished in all patients. Color-flow mapping showed complete closure in 16 (64%) patients immediately after and 20 (80%) patients 1 month after the procedure. No significant complications occurred. The advantages of this detachable coil system may reduce call migration and allow safer and more reliable execution of this procedure.
