On (b)(6) 2017, the patient presented with occlusion of the right superficial femoral artery (sfa) which was treated with two gore® viabahn® endoprostheses.As the patient also presented with chronic total occlusion of the left common iliac artery, femoro-femoral crossover bypass procedure was planned after the deployment of the gore® viabahn® endoprostheses.The access was obtained from the ipsilateral (right) side.It was reported that there was difficulty in inserting the guidewire into the occlusion of the right sfa, and therefore the physician pushed and pulled the wire multiple times to successfully advance over the occlusion.After the distal device was deployed at the intended position with no issues, the intraoperative imaging identified a dissection at the proximal end of the right sfa, possibly caused by manipulation of the guidewire; however the cause of the dissection remained unknown.The procedure continued as planned, and the proximal device was deployed distal to the ostium of the distal deep femoral artery, post-dilation performed, and then femoro-femoral crossover bypass made with no issues.As another intraoperative images showed that the dissection was not fully covered by the proximal device, it was determined to perform surgical thrombectomy to repair the dissection and close the site with a patch.After the thrombectomy the patient's activated clotting time decreased.An endovascular thrombectomy was performed in the bypass graft.As an angiography revealed no flow to the distal deep femoral artery, another thrombectomy was attempted to the artery; however no thrombosis was removed.It was reported that the no-flow to the artery might have caused by the dissection flap closing the ostium of the artery, but the cause remained unknown.Final angiography revealed flow to the artery, the physician elected to conclude the procedure.The patient tolerated the procedure.
