ABSTRACT
Background:Persistent ductus arteriosus is a common congenital cardiac disease. If it isn't diagnosed and treated on time, the patient will be suffered severe complication which can cause mortality. The surgery for ductus arteriosus closure is a treatment method which is being applied at many Surgery Center in our country. Objectives:This study aims to evaluate the results of transcatheter patent ductus arteriosus closure using amplatzer duct occluders in children admitted into national hospital of pediatrics. Subjects and method: A prospective study was carried out on 40 children with patent ductus arteriosus confirmed by echocardiography in National Hospital of Pediatrics from October 2005 to October 2006. Transcatheter closure by amplatzer was used in all patients. Changes in clinical, laboratory findings and particularly Echocardiography were obtained before and after treatment. Results: The mean age and weight of the patients were 44.86 \xb1 41.11 months and 12.44 \xb1 6.5 kg. Closure was successful in 38/40 patients (95%), complications occurred in one patient (2.5%), no death was occurred. The rate shunting was 15% after 1 day and 0% after 3 months. Conclusion: Transcatheter closure using the Amplatzer was an effective and safe treatment for patent ductus arteriosus in pediatric patients.
