[Original nitinol monowire stent for percutaneous iliac arterial reconstructions]

Nitinol monowire stents of original construction were implanted to 35 patients (aged from 36 to 84, mean 53.9) with atherosclerotic lesions of iliac arteries. Arterial stenosis ranged from 50% to 100% (mean 72.2%), ankle-brachial index (ABI) averaged 0.45+/-0.12. Initial success was achieved in 97.1% of procedures. Ultrasonography 3 days since the procedure showed the increase of ABI up to 0.78+/-0.16. Restenoses in the stented site was revealed during follow-up period (mean 24.3+/-18.3 months) in 3 patients (8.3%). In conclusion, new stent appeared to be effective tool for treatment of iliac atherosclerotic lesions. However long-term restenoses resulting from intimal hyperplasia can require repetitive revascularization.
