Abstract
ObjectiveTo evaluate the short- and mid-term efficacy of Supera interwoven nitinol stent for the treatment of femoropopliteal artery disease.
MethodsClinical data of 100 patients with 102 affected limbs with femoropopliteal artery disease who underwent implantation of Supera interwoven nitinol stent in the Department of Vascular Surgery, the First Affiliated Hospital of Sun Yat-sen University from December 2016 to August 2021 were analyzed retrospectively. Comparison of pre- and post-operative ankle-brachial index (ABI) was made using the student's t-test. Additionally, the Kaplan-Meier survival curve was used to calculate the primary and secondary patency rates for patients with at least one-year follow-up.
ResultsA total of 161 stents were implanted with a success rate of 100%. The mean length of postoperative hospital stay was (5.78±6.92) days. No serious perioperative complication occurred. The ABI increased from 0.30±0.33 preoperatively to 0.88±0.25 postoperatively (t=10.66, P<0.001). Moreover, 97 patients (99 limbs) were followed up for (18.59±13.77) months. 69.1% (67/97) of patients were significantly improved. Besides, in-stent stenosis and amputation were observed in 30.9% (30/97) and 7.2% (7/97) of cases, respectively. The mortality rate was 12.4% (12/97) and no stent-related death happened. Furthermore, 62 (62.6%, 62/99) limbs were followed up for over 12 months. The 3-, 6- and 12-month primary patency rates were 97.6%, 87.8% and 75.6%, respectively, and the secondary patency rates were 97.6%, 95.1% and 90.2%, respectively.
ConclusionsThe short- and mid-term efficacy of Supera interwoven nitinol stent for the treatment of femoropopliteal artery disease appears to be safe and effective.
