French (Fr) sheath, 8.5Fr Parent sheath and 6Fr AL-1 catheter, 0.035” Radifocus guidewire was passed through the graft. Because of the tight curve in the middle of the graft, we chose self-expandable 7 x 60mm Smart stent. After predilation with 4 x 30 mm Sterling and 6 mm x 40 mm Sterling balloon, Smart stent was deployed to cover the 6mm ePTFE graft. Post-procedural angiography demonstrated a widely patent stent with good antegrade RPA ow. The pressure of the main pulmonary artery decreased from 67/27(46) mmHg to 49/10(27) mmHg after stent implantation. Clopidogrel was added to aspirin and warfarin, and she discharged from the hospital with good patency of the graft.
Learning Points of the Procedure: This is the rst report of successful penetrating and stenting of chronic total occlusion of the ePTFE graft after RPA bypass surgery. Penetrating chronic total occlusion of the ePTFE graft at the pulmonary artery site with guidewire could be per- formed safely. Simple balloon dilation was not enough to maintain
the patency of the occluded graft. Self-expandable stent might be a good option for pulmonary artery bypass stenosis/occlusion which runs anatomically complicated courses. Further study with a larger population is needed to investigate the e ect of stent implantation in this setting and to establish adequate antithrombotic therapy in such cases.
