[Occlusion of patent ductus using the Rashkind system. Initial experience].

Three patients were submitted to the Rashkind device technique for closure of a patent ductus arteriosus. The percutaneous transvenous technique was employed in every cases. A 12 mm prosthesis was utilized in one case and 17 mm prostheses in the other two cases. In the first case, after temporary occlusion of the ductus arteriosus, the prostheses was removed due to the technical impossibility of evaluation of the proximal umbrella position. In the second and third cases, the prostheses were duly liberated in the proper position, thus occluding the defects. This technique does not require general anesthesia, is indicated in patients over 6 kgs of body weight, and is a therapeutic alternative to the habitual surgical procedure.
