[Percutaneous closure of a ductus arteriosus with a Gianturco coil in an infant weighing 3.2 kg]. / Cierre percutáneo del conducto arterioso con espiral de Gianturco en lactante de 3.2 kg de peso.

We report a case of an infant, with Down's syndrome that weighted 3.2 K and had cardiorespiratory distress due to patent ductus arteriosus. Echocardiogram showed evidence of pulmonary hypertension. Cardiac catheterization was performed, the ductus was a A-2 type. It had 1.5 mm of diameter. Moderate pulmonary hypertension was found with a QP/QS = 1.8. A Gianturco coil was placed in the ductus via the femoral vein: the size of the coil was 5 mm/5 cm. There was not post-procedural evidence of patency of the ductus. We conclude that the closure of the ductus by percutaneous means in symptomatic patients is a good treatment alternative.
