2026年11月3日 更新者：iVascular S.L.U.

前瞻性、多中心、非随机、单臂观察研究，以评估 iCover 覆膜支架治疗主髂动脉闭塞症的安全性和有效性

The objective of this prospective, multi-center, non-randomized, single-arm observational study is to evaluate the safety and the efficacy of the iCover covered stent over a 24-month follow-up period for the treatment of de novo iliac occlusive lesions, defined by a significant vessel stenosis ≥70%, in patients with symptomatic arteriopathy of the lower limbs (Rutherford class 2 to 5).

详细说明

This is a prospective, single-arm, multinational, and multicenter study conducted to evaluate the safety and efficacy of the iCover covered stent for the treatment of de novo iliac occlusive lesions (common and/or external iliac arteries) in patients with symptomatic lower limb arteriopathy. The primary endpoint of the study is primary patency, defined as the absence of restenosis in the target lesion over a 12-month follow-up period in patients who did not undergo a reintervention on the target lesion. Restenosis is defined as a reduction in the luminal diameter of more than 50%, assessed either by duplex ultrasound (considered as a peak systolic velocity index ≥ 2.4 at the target lesion) or by angio-CT (multiplanar reconstruction). Secondary endpoints include: technical and procedural success rate, freedom from all major adverse events, incidence of procedure- or device-related major local complications at the treated lesion, rate of SAEs, major amputation rate at the target limb, primary sustained clinical improvement (improvement in Rutherford classification), primary and secondary patency rates, TLR and TVR rates, and changes in ABI, the Walking Impairment Questionnaire, and the EQ-5D questionnaire from baseline.

In case of death, the vessel is considered as patent as long as no restenosis was detected during the last visit before the patient died.
