Primary stent placement for recanalization of iliac artery occlusions: using a self-expanding spiral stent
1Department of Radiology, Chonnam University Medical School, #8 Hackdong, Kwangju, Korea 501-757.
Insights
Self-expanding spiral stents safely and effectively recanalized iliac artery occlusions in 34 patients. This primary intervention achieved high technical and clinical success rates with minimal complications.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Interventions
Background:
- Iliac artery occlusions cause significant morbidity, including intermittent claudication and resting pain.
- Traditional treatment options may be limited or carry higher risks.
Purpose of the Study:
- To evaluate the clinical outcomes of using self-expanding spiral stents for iliac artery recanalization.
- To assess the safety and efficacy of this endovascular approach as a primary treatment.
Main Methods:
- Retrospective analysis of 36 iliac artery occlusions in 34 patients treated with self-expanding spiral stents.
- Assessment of technical success, clinical success, lesion characteristics, and complications.
- Follow-up included angiography and clinical evaluation of symptoms (Fontaine classification).
Main Results:
- Successful recanalization of all 36 lesions was achieved with 45 stents deployed.
- High technical success (100%) and clinical success (94%) rates were reported.
- Low complication rate (one hematoma) and low reocclusion rate (5%) were observed.
Conclusions:
- Self-expanding spiral stents are a safe and effective primary treatment for iliac artery occlusions.
- This device offers a viable endovascular solution for patients with iliac artery disease.
Purpose:
To report the clinical results for recanalizations of an occluded iliac artery by a self-expanding spiral stent.
Methods:
We attempted to recanalize 36 iliac artery occlusions in 34 patients [33 men, 1 woman, aged 51-75 years (average 61.6 years)]. The average lesion length was 6.92 cm (range 1-14 cm). The patients' chief complaints were intermittent claudication and resting pain. Fontaine classification was assigned before and after the procedure. Technical and clinical success were also analyzed.
Results:
Forty-five stents were successfully deployed in 34 patients. All 36 lesions (13 in the external iliac artery, 12 in the common iliac artery, and 11 in both) were patently recanalized on angiography. The follow-up period ranged from 6 months to 36 months (mean 11.9 months). Fourteen stents (39%) with incomplete expansion were dilated with a balloon catheter. Good technical (100%) and clinical (94%) results were obtained. The only complication was one hematoma at the puncture site. Reocclusions were noted in two lesions (5%) at 1 week and 15 months, respectively.
Conclusion:
A self-expanding spiral stent is a safe and effective device for recanalization of an iliac artery occlusion as the primary stent without any previous intervention.
