Background and objectives: To assess the safety and efficacy of transcatheter closure of residual ductal flow after initial surgical ligation of the arterial duct.
Subjects and methods: Between June 2005 and December 2009, transcatheter occlusion of residual postsurgical ductus arteriosus was performed in six children.
Results: The mean patient age was 10±5.5 years; mean post-procedural time since the initial surgical closure was 6.3±4.5 years. The mean diameter of the patent ductus arteriosus on angiography was 1.3±0.5 mm (range, 0.8 to 2.4 mm). Three different types of coils were used successfully without any complications.
Conclusion: Transcatheter occlusion of residual postsurgical arterial duct is a safe and successful procedure. However, attention should be paid due to the distorting shape of the arterial duct.
