Coil occlusion of patent ductus arteriosus. | LitMetric

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 >or=2.5 mm.

Methods And Results: A retrospective survey of the outcome of coil occlusions for PDA >or=2.5 mm before and after the 0.052-inch coil became available found that (1) the frequency of PDA >or=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 >or=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 >or=2.5 mm, and contributed to a better likelihood of coil occlusion for PDA >or=4 mm.
