Long-Term Outcomes of Common Femoral Artery Stenting

Abstract

The purpose of this study was to report the 5-year outcome relative to endovascular repair of the common femoral artery (CFA) for occlusive disease. Thirty-six consecutive patients (40 limbs) underwent stenting for CFA lesions. Patients were followed up systematically within a prospectively maintained database over 5years. Follow-up included clinical examination, duplex scan, and biplane X-ray at 1, 6, 12months and yearly thereafter. Indications for endovascular repair of the CFA included 25 patients (70%) for claudication and 11 patients (30%) for critical limb ischemia. Mean follow-up was 64months. Two patients were lost to follow-up. The mortality rate at 5years was 38%. At 3 and 5years, primary sustained clinical improvements were 77% and 73%, respectively. In-stent restenosis rate was 28%. The significant predictors of in-stent restenosis were deep femoral artery stenting (P=0.0007) and type III lesions (P=0.014). Freedom from target lesion revascularization and target extremity revascularization were 79% and 73%, respectively. One stent fracture was noted at the first year follow-up without clinical consequence, and no other stent fracture was noted during the remainder of the study. Endovascular repair of the CFA and its bifurcation seems to provide sustained clinical and morphological long-term results. Fear of stent fracture and local complications due to hip mobility are no longer relevant.
