Abstract:
Objective To evaluate the clinical effect of transcatheter closure with Amplatzer duct occluder offers in infants with patent ductus arteriosus(PDA).Methods Thirty-seven PDA infants underwent transcatheter closure of PDA at(8.7 ? 3.3)months and weight of(8.6 ? 3.5)kg.A lateral view aortogram was made to determine the morphology and the narrowest diameter of the ductus and selected the size of the device.Occluder was implanted using the anterograde venous approach.Follow-up evaluations were made with chest X-ray and echocardiogram at 24 hours and 1,6 and 12 months after implantation.Results The narrowest diameter of the ducts measured by angiographically was(3.3 ? 1.5)mm.Ninteen patients(54.29%) achieved immediate complete occlusion.On color Doppler the closure rates at 1 month after implant were 34 cases(97.14%).No residual shunt exsisted in all implanted patients at 6 and 12 months follow-up.Procedure time at(57 ? 43)minutes and fluoroscopy time(23.0?14.9)minutes.Conclusions Percutaneous PDA closure with the Amplatzer duct occluder decice is an safety and effective method for the treatment of PDA in infants,but caution shall be exercised to the anatomic characteristics in the infant age group in solving clinical complications.
