Insights
Self-expandable nitinol stents show high long-term patency for common femoral artery (CFA) disease, offering a viable alternative to surgery. This study confirms excellent technical success and low complication rates for CFA stent placement.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Imaging
Background:
- Common femoral endarterectomy is the standard treatment for atherosclerotic common femoral artery (CFA) disease.
- This procedure has significant associated morbid-mortality rates.
- Endovascular options are being explored as alternatives.
Purpose of the Study:
- To evaluate the long-term patency of common femoral artery (CFA) lesions treated with stent placement.
- To identify risk factors associated with restenosis after CFA stenting.
- To compare outcomes of endovascular stenting with traditional surgical approaches.
Main Methods:
- A retrospective observational study of patients undergoing endovascular stent placement for CFA lesions.
- Clinical follow-up and multi-detector computed tomography angiography (MD-CTA) were used to assess in-stent restenosis (ISR) and patency rates.
- Analysis included primary, assisted, and secondary patency, as well as freedom from target lesion revascularization.
Main Results:
- 100% technical success was achieved in 35 extremities treated with nitinol stents.
- Mean follow-up was 32.2 months, with high estimated primary (79.5%) and secondary (96.3%) patency rates at 60 months.
- In-stent restenosis (ISR) rates were 55.6% for <20%, 33.3% for 20-70%, and 11.1% for ≥70%.
Conclusions:
- Endovascular stenting with self-expandable nitinol stents in CFA lesions offers high technical success and low complication rates.
- While mild intimal hyperplasia was noted, long-term patency remains high.
- CFA stent placement is a suitable alternative therapeutic option for selected patients with common femoral artery disease.
Background:
Despite considerable morbid-mortality rates, common femoral endarterectomy is still considered the gold standard for atherosclerotic common femoral artery (CFA) disease. The aim of this study was to demonstrate computed tomography angiography based long-term patency after CFA stent placement and to analyze associated risk factors for restenosis.
Methods:
A retrospective and observational study was carried out in consecutive patients treated with endovascular stent placement in CFA lesions. A clinical follow-up and imaging study was performed using MD-CTA to assess different degrees of in stent restenosis (ISR) and primary, assisted, and secondary patency rates.
Results:
In a 5-year period, 35 extremities were treated in 33 patients with self-expandable nitinol stents. The technical success was 100% without complications related to the procedure. The mean follow-up (FU) was 32.2 months, and 8 limbs were lost. The degree of CFA stenosis was reduced from 79.69 ± 26.47% to 11.23 ± 24.53%. ISR < 20%, 20-70%, and ≥ 70% was evident in 15 (55.6%), 9 (33.3%), and 3 (11.1%) limbs, respectively. Estimated primary, assisted, and secondary patency was 79.5, 96.3, and 96.3%, respectively, after 24 months and 79.5, 96.3, and 96.3%, respectively after 60 months, with a freedom of clinical driven target lesion revascularisation rate of 87.8%.
Conclusion:
Endovascular treatment with self-expandable nitinol stents in CFA lesions had a high technical success rate and was related to few complications. A mild form of intimal hyperplasia was observed in a considerable number of cases. However, long-term patency was high; therefore, CFA stent placement might be a suitable therapeutic alternative in selected patients.
