Abstract Objective: To report the initial experience of using Viabahn endoprothesis to treat the restenosis in superficial femoral artery. Materials and Methods: Ten cases of superficial femoral artery(SFA) in-stent restenosis were admitted due to lower limb ischemia in April 2013. All of the 10 patients were suffering from Fortaine Ⅱb or Ⅲ stage ischemia, with mean age of 68 years old. Preoperative CTA demonstrated obvious SFA in-stent restenosis, in which there were 9 total occlusion of the nitinol stents, the ABI: 0~0.48. We accomplished re-intervention with Viabahn(5~7 mm in diameter) for all 10 cases. Evaluation of treatment at immediate angiography, postoperative ABI, and 1 week after intervention for Fortaine ischemia classification. Results: Fifteen Vibahn endoprothesis were successfully implanted in all of the 10 cases. There are no residual stenosis in the immediate angiography with a significant improvement of ABI to 0.76~0.96(t=-11.589，P=0.000). The Fortaine ischemia classification were improved from Ⅱb toⅠand from Ⅲ to Ⅱa or Ⅰstage. Conclusion: The Viabahn endoprothesis might be a safe and effective approach for the treatment of SFA in-stent restenosis.
