[Percutaneous closure of patent ductus arteriosus using the Amplatzer vascular Plug II].

UNLABELLED: The Amplatzer vascular II Plug (AVPII) 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 - 4.7 mm). 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.
