title: [The percutaneous closure of patent ductus arteriosus with the Rashkind technic. The initial experience of the Instituto Dante Pazzanese de Cardiologia, São Paulo, Brazil].
abstract: The authors report their experience with the percutaneous closure of the patent ductus arteriosus with the Rashkind technique. They performed 42 procedures with a success of 97.6% and one embolization episode. The mean age was 8.7 +/- 6.7 years, the mean weight was 25.0 +/- 15.8 Kg and the minimum diameter of the ductus was 4.0 +/- 1.3 mm. The immediate overall prevalence of residual shunt was 48.8% falling to 21% in a mean follow-up of 17 +/- 13 months in 29 cases. Two patients underwent late reocclusion: one with a new umbrella and the other with a coil. Another patient had an immediate severe residual shunt and it was reoccluded in the same procedure with a coil. The anatomical type and minimum internal diameter of the ductus, age and weight, size of the umbrella and the rotation of the umbrella were not predictors of residual shunt. There were no deaths, hemolysis, endarteritis or fracture of the umbrella's arms. One patient remained with a slight gradient in the left pulmonary artery. The authors conclude that the Rashkind technique is safe and efficient and has good long term results. It should be considered as the first line therapeutic modality in the treatment of selected patients with persistent ductus arteriosus.
