Venous, traumatic, embolic, and nonatherosclerotic etiologies are excluded. CLTI is a clinical syndrome defined by the presence of peripheral artery disease (PAD)in combination with rest pain, gangrene, or a lower limb ulceration >2 weeks duration. The term CLTI is preferred over critical limb ischemia, as the latter implies threshold values of impaired perfusion rather than a continuum. These Global Vascular Guidelines (GVG)are focused on definition, evaluation, and management of CLTI with the goals of improving evidence-based care and highlighting critical research needs. The use of a < 8 mm-diameter stent was associated with a reduced primary patency.Ĭhronic limb-threatening ischemia (CLTI)is associated with mortality, amputation, and impaired quality of life. The use of self-expanding covered stents provided excellent early and mid-term results in the treatment of obstructive disease of the EIA, also in cases of high EIA tortuosity and high grade of calcifications. 001) was negatively associated with primary patency. After univariate analysis, the use of a stent with diameter < 8 mm (HR 8.5, 95%CI 3.24-14.22 P <. At 42 months (mean, 25 months), primary patency was 89.8% (95%CI 83-98) the presence of EIA tortuosity (tortuosity index > 1.25, 87.7 ± 11% vs 89.9 ± 8% P =. There was one perioperative death (1.4%) and procedural complication rate was 6.5%. Mean lesion length was 6.9 ± 2.4 cm 30% had moderate/severe EIA calcifications and the mean iliac tortuosity index was 1.17 ± 0.13. TASC C/D lesions were present in 72% and iliac complete occlusion in 30%.

Ninety-three patients (mean age, 69 ± 9 years 81% males) were treated for disabling claudication in 44%, rest pain in 28%, and tissue loss in 28%.

Patency and limb salvage rates were estimated with Kaplan-Meier curves. All patients were treated with the Viabahn (W.L Gore & Associates, Inc., Flagstaff, AZ-USA) stent. We conducted a multicenter retrospective study (2015-2021), including patients receiving primary endovascular treatment of external iliac artery occlusive disease with self-expanding covered stents. To describe the early results and mid-term patency rates of external iliac artery (EIA) stenting using self-expanding covered stents.
