Insights
Self-expanding endoprostheses offer a safe and effective treatment for complex iliac artery lesions. This study shows high technical success and good long-term patency rates for patients undergoing stent placement.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Devices
Background:
- Iliac artery occlusive disease presents a significant challenge in peripheral vascular interventions.
- Complex iliac stenoses and occlusions often require advanced treatment strategies.
Purpose of the Study:
- To evaluate the safety and efficacy of self-expandable endoprostheses for treating complex iliac artery lesions.
- To assess early and late outcomes, including technical success, complications, and patency rates.
Main Methods:
- A retrospective analysis of 125 patients with 63 iliac occlusions and 62 complex iliac stenoses.
- Stent placement using self-expandable vascular endoprostheses was performed.
- Outcomes were assessed based on technical success, complication rates, and cumulative patency.
Main Results:
- High early technical success rate of 98% was achieved.
- Total complication rate was 4%, with major complications in 1.6% of patients.
- Cumulative patency was 100% at 6 months and 89.4% at 24 months, with 12 repeat procedures for late reobstruction.
Conclusions:
- Stenting of iliac arteries with self-expandable endoprostheses is a safe and effective treatment modality.
- The procedure demonstrates favorable long-term patency and manageable complication rates for complex iliac lesions.
Abstract:
Within a 3-year period, 125 patients with 63 iliac occlusions and 62 complex iliac stenoses underwent stent placement using self-expandable vascular endoprostheses. Early technical success rate was 98%, with a total complication rate of 4%. Major complications were seen in 1.6%. Early reobstruction occurred in 4 patients with previous occlusions. Late reobstruction due to a clinically relevant restenosis or reocclusion occurred in 10 patients and required 12 repeat interventional procedures. Cumulative patency, excluding early technical failure, was 100% at 6 months and 89.4% at 24 months. Stenting of iliac arteries using self-expandable endoprostheses is a safe and effective treatment of complex iliac lesions.
