PARRA-BRAVO, Rafael et al. Percutaneous closure of patent ductus arteriosus using the Amplatzer vascular Plug II. Arch. Cardiol. Méx. [online]. 2011, vol.81, n.2, pp. 108-113. ISSN 1405-9940.

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.
