Coil Occlusion of Patent Ductus Arteriosus Impact of 0.052-Inch Gianturco Coil Without Amplatzer Duct Occluder

Abstract

Background Coils are the only devices available for transcatheter occlusion of patent ductus arteriosus (PDA) in Japan. Since April 1999, we have introduced a 0.052-inch Gianturco coil (0.052-inch coil) to close PDA ≥2.5 mm. Methods and Results A retrospective survey of the outcome of coil occlusions for PDA ≥2.5 mm before and after the 0.052-inch coil became available found that (1) the frequency of PDA ≥2.5 mm among all candidates for coil occlusion significantly increased after the availability of a 0.052-inch coil (p<0.01); (2) deployment complicated by migration (p<0.01), and prolonged procedure time (p<0.05) were significantly decreased after the introduction of the 0.052-inch coil. In a multivariate logistic regression model for uneventful deployment adjusted for age, pulmonary to systemic flow ratio, and use of a 0.052-inch coil, use of the 0.052-inch coil significantly decreased eventful deployment (p<0.05); and (3) successful deployment of a coil for PDA ≥4 mm significantly increased with the 0.052-inch coil (p<0.01). Complete occlusion was achieved once deployment was successful. Conclusion Introduction of the 0.052-inch coil decreased complicated coil occlusion deployment for PDA ≥2.5 mm, and contributed to a better likelihood of coil occlusion for PDA ≥4 mm.

Transcatheter coil occlusion of perimembranous ventricular septal defects

“…Flipper and 0.052@ Gianturco coils are commonly used for percutaneous closure of a PDA in Japan [13]. Morphological similarities between the conical ampulla of a PDA and the septal aneurysm accompanied by a pouch of the tricuspid septal leaflet, which is commonly seen in a spontaneously closing perimembranous VSD, encouraged us to use these coils for percutaneous closure of this type of defect.…”

A Case of Patent Ductus Arteriosus in an Elderly Patient Treated by Thoracic Endovascular Aortic Repair

“…On the other hand, endovascular approaches using Amplatzer PDA closure or coil embolization are less invasive than open surgery. 2,3) A limited number of hospitals perform these procedures in Japan. When the arterial duct diameter is smaller than 12 mm, the complete closure rate achieved by Amplatzer PDA closure is high (98%-100%).…”

Successful Closure of a Patent Ductus Arteriosus Using an Aortic Stent Graft

“…The endovascular approach to PDA is less invasive than procedures such as coil embolization 2,3) or the use of a PDA occluder. In particular, the Amplatzer Duct Occluder offers safe, effective treatment for moderate-tolarge PDAs (≤12 mm) with a high success (97%-99%) and complete closure (98%-100%) rates, and serious complications are rare.…”
