Although many articles have been published about transcatheter coil occlusion, few studies have been conducted on the long-term outcomes of patent ductus arteriosus closure with a coil. This study is an examination of the follow-up data of patients who underwent transcatheter patent ductus arteriosus closure with a coil.


Between May 1996 and May 2018, 243 patients underwent transcatheter patent ductus arteriosus closure with a coil. The patients were divided into 2 groups based on the timing of the use of ductal occluders at the facility. Until the end of 2005, every ductus was closed with a coil. Since initiating the use of ductal occluders in 2006, coils are mostly used to close small, elongated ducts, and occasionally, some complex ducts.


The median age of the patient was 4.33 years, the median weight was 15 kg, and the median duct diameter was 2 mm. In this study group, 98 (40%) patients were male and 145 were female (60%). The angiographic features of the ductus were classified as type A in 126 patients, type B in 15, type C in 6, type D in 9, type E in 74, and 13 were recorded as other types. In 238 of the patients, the patent ductus arteriosus was successfully closed with a coil. In 5 (2.2%) cases, the procedure was unsuccessful. Echocardiography follow-up continued for an average of 4.1+-4.1 years (1 day-19 years). A residual shunt was observed in 42 patients, and spontaneous occlusion was seen in 29 of the 42 patients.


The results of this study indicated that closure of the patent ductus arteriosus with a coil was a safe and effective method.
