BACKGROUND: Endovascular treatment of the common femoral artery (CFA) and its bifurcation is currently recommended for patients with hostile groin (prior femoral bifurcation open surgery, history of radiotherapy) or severe comorbidities (advanced age, frailty, obesity). Preliminary results have shown favorable outcomes. Among the different endovascular techniques (atherectomy, intravascular lithotripsy, plain balloon angioplasty, drug-coated balloon angioplasty, stenting), stents are mainly used but the best type of stent to use is still debated. The aim of this study was to assess the value of balloon-expandable stents (BES) and self-expandable stents (SES) for stenosis of the femoral bifurcation.
METHODS: Consecutive patients with stenosis of the CFA and its bifurcation were included from 2016 to 2022. Demographic data, the type of stent used, procedural data, and angiographic variables were collected. Groups were defined according to the type of stent implanted. Primary patency was defined as a binary end point based on a duplex ultrasound peak systolic velocity ratio of ≤2.4 as assessed by duplex ultrasound examination, in the absence of clinically driven target lesion revascularization (TLR) or bypass of the target lesion. Secondary outcomes were clinical sustained improvement, freedom from TLR at 12 months, mean ankle-brachial index improvement, primary-assisted patency, and secondary patency.
RESULTS: A total of 90 procedures conducted in 77 patients were included in this study, 26 in the SES group and 64 in the BES group. The most common symptomatology according to the Rutherford classification was class 2, 3, and 4 (28%, 48%, and 8%, respectively). The type of lesions in the CFA, assessed using the Azema classification, were comparable between both groups (SES/BES group type 2: 31%/27%; type 3: 54%/62%). At 12 months, the primary patency rates for SES and BES were 88% (26/26 patients) and 72% (58/64 patients) (P = .10). At 12 months, freedom from TLR rates for SES and BES were 97% vs 81%, respectively (P = .13).
CONCLUSIONS: SES for CFA stenosis show a trend toward better patency and freedom from TLR rates at 12 months. However, controlled studies are warranted to further investigate the significance of this trend.
