Early Outcomes of Interwoven Nitinol Wire Stent Placement versus Endarterectomy for the Treatment of Atherosclerotic Disease of the Common Femoral Artery.

PURPOSE: To compare the clinical outcomes of common femoral artery (CFA) atherosclerotic disease treated with either surgical endarterectomy or an interwoven nitinol wire stent system.

MATERIALS AND

METHODS

A retrospective review was conducted of all patients with chronic, de novo atherosclerotic CFA disease treated with surgical endarterectomy (CFAE) or stent placement between July 2019 and March 2022. Outcome measures assessed up to 12 months after procedure included clinical improvement, primary restenosis, target vessel revascularization (TVR), major adverse limb events (MALEs), and all-cause mortality.

RESULTS

Thirty-nine stents were deployed in 33 patients, and 56 CFAEs were performed in 55 patients. No differences were noted in the rate of primary patency (95.5% vs 94.4%, P = .618), TVR (2.9% vs 1.8%, P = .777), MALE (5.1% vs 5.4%, P = .949), and all-cause mortality (14.1% vs 3.6%, P = .076) between the stent and CFAE groups up to 12 months after procedure. There was greater improvement in median clinical severity in the stent group than in the CFAE group (Rutherford score change of 3.0 vs 1.5, P = .013). The median length of stay was less for the stent group (3 vs 7 days, P = .002), and there was a lower likelihood of severe or disabling adverse events in the stent group (0 vs 9 cases, P = .010).

CONCLUSIONS

Patients treated with an interwoven nitinol wire stent had patency rates comparable to those treated with CFAE while having a lower incidence of severe adverse events and a shorter length of hospital stay than those who underwent CFAE.
