title: Multicenter Off-Label Use of Nit-Occlud Coil in Retrograde Closure of Small Patent Ductus Arteriosus.
abstract: We studied the safety and efficacy of closing patent ductus arteriosus by Nit-Occlud coils via retrograde approach. This is a retrospective study of 46 attempts to close ducts by this method in two hospitals in Egypt and Iran. Ductus arteriosus was crossed by left or right Judkins or endhole catheters. The coil was delivered via the same catheter or the provided endhole catheter after exchange. The procedure was successful in 42 out of 46 attempts. Fluoroscopy and procedural times were significantly shorter when the catheter was not exchanged. This method is effective and safe for the closure of small ducts. Crossing the duct and delivering the coil by a left Judkins catheter is the easiest and fastest way to perform this method.
