Background: We tried to occlude the duct with retrievable coil device(Duct-Occlud) in 6 children with patent ductus arteriosus(PDA). And, we reviewed the technical aspects and the short-term results.
Methods: PDA occlusion with "Duct-Occlud" system was attempted in 6 patients with small to moderate size PDA from January 1999 to November 1999. Mean age of the patients was 6.56 (1.33 to 14)year. After estimation of the size of PDA, retrievable coil device(Duct-Occlud) was inserted through the femoral vein route. The angiocardiography was performed 10 minutes after the procedure. On next day and one week later, the follow-up echocardiogaphy was checked. And then, it repeated at 3 months, 6 months later. The follow-up duration was 5.5(1 to 11) months.
Results: The Qp/Qs was 1.44(1.25 to 1.63), Rp/Rs 0.09(0.03 to 0.15), size of pulmonary end 2.73(2.1 to 3.5)㎜, aortic end 4.58(2.8 to 5.5)㎜, length 5.83(3.8 to 8)㎜. The complication of the procedure occurred in one patient by uneventful earlier detatchment. Flow disturbance was not developed.
Conclusions: Coil occlusion with the Duct-Occlud system is a safe and effective method for percutaneous closure of small to moderate-size PDAs. Larger numbers of treated patients and longer follow-up period would be necessary to more precisely define the efficacy, and most appropriate indications for this system.
