Belgian Study to Assess the Efficacy and Safety of the RESTORER Iliac Stent for Treatment of Aorto-iliac Lesions.

Prospective, single-arm, multicentre, physician-initiated clinical study to assess the long-term (up to 24 months) safety and efficacy of the RESTORER peripheral stent system (iVascular) for the treatment of iliac lesions in 200 subjects, in a controlled clinical setting post CE-certification when used according to the IFU with focus on the treatment of complex TASC A, B, C and D Aorto-iliac lesions. The primary endpoint of the study is freedom of any TLR, major amputation or restenosis (defined as significant stenosis on duplex ultrasound (\>50%, systolic velocity ratio greater than 2.4) within 12 months. Secondary endpoints are: technical success during procedure, and during the follow-up period: primary patency, stent graft occlusion rate, ABI, freedom from target lesion revascularization, clinical success (improvement of Rutherford classification), change in walking impairment questionnaire, change in quality of life questionnaire, freedom from above-the-ankle target limb amputation, and mortality. A subanalysis will be done to compare the results using the TASC classification, lesion location (AIE, AIC, bilateral, kissing configuration), gender, diabetes mellitus and Rutherford in terms of patency, frequency of TLR and clinical outcome at 12 and 24 months.
