GALVEZ-CANCINO, Franco et al. Percutaneous closure of patent ductus arteriosus in infants using the Amplatzer vascular plug II. Rev. Mex. Cardiol [online]. 2013, vol.24, n.1, pp.29-34. ISSN 0188-2198.

Percutaneous closure of patent ductus arteriosus (PDA) is a well established treatment modality. The Amplatzer vascular plug II (AVP II) is a self-expandable occluder device, indicated for arterial or venous occlusions in the peripheral vasculature. We describe our initial clinical experience in percutaneous closure of PDA using the AVP II in children. Device size was selected according to the size and morphology of the CAP, with a diameter greater than 100% of the minimum diameter of the CAP. The devices were implanted through a pod femoral vein or artery. In 18 patients, AVP II was used for occlusion of PDA. The median age was 24 months (range 6-51) and mean weight 10.5 kg (range 4.8-16.5). The narrowest diameter of the CAP showed a median of 1.1 mm (range 0.3-7.0). Successful implantation was achieved and angiographic occlusion in 14 patients (77.8%). The size of the implanted device showed a mean of 3.9 ± 2.4 times the minimum diameter of the CAP. Two patients were referred for surgery. There were two embolizations. Transthoracic echocardiography 24 hours confirmed total occlusion in 13 cases (72.2%). During the monitoring period there are no reported complications. Percutaneous closure of PDA < 2 mm AVP II is a safe and effective, particularly for occlusion of small-diameter vessels with low flow.
