Transcatheter closure of coronary arterial fistula in children and adolescents

摘要: Background Transcatheter closure of coronary arterial fistula (CAF) is being utilized increasingly as an alternative to surgical closure, but most the literature on transcatheter CAF in children and adolescents consists case reports small series. The aim this study was therefore describe our experience percutaneous adolescents. Methods Between April 1998 December 2012, 37 with congenital underwent closure. After aortic root angiography selective angiography, a guidewire positioned fistula. In some cases, arteriovenous wire loop (AV loop) created. sheath passed along site desired occlusion One or more devices were selected embolize fistula. Results Occlusion placed 33 procedures (32 patients). Occlusion unsuccessful five patients. Duct occluders 12 procedures, coils 11 (10 patients), muscular ventricular septal six, vascular plugs four procedures. tricuspid valve injured two patient giant aneurysm had thrombosis within after There no deaths, dissection myocardial infarction. Conclusion Transcatheter feasible anatomically suitable injury involved AV methods can occur thrombus formation possible blind pouch residual Long-term follow up necessary.
