title: Use of a balloon-expandable, radially reinforced ePTFE endograft after remote SFA endarterectomy: a single-center experience.
abstract: OBJECTIVE
  To report our experience with endovascular femoropopliteal bypass grafting using a distensible, radially reinforced polytetrafluoroethylene endograft combined with remote endarterectomy.
  
  
  METHODS
  Forty-one patients (33 men; mean age 70 years, range 45-79) with symptomatic femoropopliteal occlusive disease underwent remote endarterectomy of the superficial femoral artery (SFA) followed by implantation of a balloon-expandable Enduring endovascular graft. All patients entered an extensive surveillance program, including angiography and duplex scanning at regular intervals.
  
  
  RESULTS
  Endarterectomy and endograft implantation were ultimately successful in all patients; 5 (12%) technical difficulties occurred intraoperatively and were treated with additional endovascular techniques. Control angiography at 1 week postoperatively demonstrated a patent endograft in 39 (95%) patients. Mean ankle-brachial index increased significantly from 0.57 to 0.91 (p < 0.001). Including the 2 early failures, 18 occlusions were documented over a median 15-month follow-up (range 3-24), due mainly to significant stenosis at the proximal and distal anastomoses. In 8 of 10 successfully reopened and revised endografts, reocclusion occurred after a median interval of only 1.8 months. Life-table analysis revealed cumulative primary and secondary patency rates of 42% and 56%, respectively, at 18 months. In the last 12 cases, the proximal end of the graft was sutured end-to-end to the transected SFA, which improved the short-term secondary patency rate to 83%.
  
  
  CONCLUSIONS
  Insertion of the Enduring endovascular graft following remote endarterectomy effectively results in a less invasive treatment for femoropopliteal occlusive disease. Additional technical refinements of the procedure may be required to avoid early procedure- and graft-related failures.
