Purpose:
To evaluate the feasibility and middle term patency results, for endovascular treatment of peripheral aneurysms, using covered stents.
Materials And Methods:
Between December 1993 and may 2000 25 peripheral aneurysms on 24 patients, mean age 67.8 years (42-81), were treated with covered stents (Cragg EndoPro system or passenger, hemobahn, Word Medical). Aneurysm locations were: 17 iliac, 4 popliteal, 1 femoral, 1 subclavian, 1 carotid. The follow-up range from 1 to 75 months (mean 30.1 months).
Results:
Successful aneurysm exclusion was achieved in all patients, while maintaining good lower extremity perfusion. All but one stent remained patent during the early follow-up period. At one year 94.4% stents were patent, at two years 90.2.
Conclusion:
Treatment of peripheral aneurysms with covered stents has a high rate of immediate procedural and clinical success. At middle term follow-up patency is encouraging except with popliteal procedure, however long term follow-up and larger series is warranted to assess the place of this procedure as an alternative to the surgery.
