Cierre percutáneo del conducto arterioso permeable utilizando el Amplatzer vascular Plug II

the amplatzer vascular plug ii (avp ii) is a self-expanding occluder device, indicated for arterial and venous occlusion in the peripheral circulation. objective: to describe our initial clinical experience with the avp ii, in the percutaneous closure of small patent ductus arteriosus. method: we retrospectively analyzed seven patients who underwent percutaneous closure of patent ductus arteriosus. the avp ii was chosen with a diameter greater than 50% of the minimum diameter of the ductus arteriosus. results:patients showed a ductus arteriosus with a diameter of 1.5 ± 1.4 (range: 0.8 - 4.7mm). successful implant was achieved with adequate angiographic occlusion in 6 patients. one patient was sent to surgery. we only found a major complication. transthoracic echocardiography at 24 hours, confirmed the complete occlusion in this patients. the follow-up was 10.6 ± 9.1 months. conclusion: the avp ii in this group of patients was shown to be safe and effective for percutaneous closure of patent ductus arteriosus.
