ABSTRACT

The purpose of the present study was to assess the effectivity of transcatheter occlusion of the patent ductus arteriosus (PDA) with Gianturco modified Cook detachable Coil with diameter 3, 5 y 8 mm x 5 loop. In 10 months were selected eight patients with PDA less of 5 mm by Echo-Doppler. One case showed preductal aorta coartation without significant gradient. The procedure was performed by retrograde way with Seldinger’s technique by femoral artery and using 5F catheter system delivery. The Coil was delivered with two loops in the pulmonary side and three loops in aortic ampoule and 15 minute after, aortic angiographic was performed to determinate residual shunts. The Coil diameter was 2.5 times the PDA diameter. The pulmonary artery pressure systolic was from 28 to 48 mmHg (median 34.5 mmHg), Qp/Qs from 1.12 to 1.92 (median 1.38), PDA diameter 1.2 to 5.0 (median 2.42). The immediately complete occlusion of the ductus was obtained in five patients (62.5%). Two patient showed Coil embolism to the right pulmonary artery. One case was recovered with coronary wire guide 0.014", and another we can’t recovery and leave without complication. Another case was failed because the Coil was small about PDA diameter. This work is part of the our initial experience in the delivery Coil for the occlusion the ductus arteriosus with 62.5% exit, we consider this is related with the trainership bend, but it’s promising procedure. We concluded that transcatheter occlusion of the arterial duct with Cook detachable Coils was successful calculating size Coil is 2.5 times more than PDA diameter.
