Summary
Carotid artery stenting (CAS) via the contralateral transradial approach is safe and feasible, offering an alternative to femoral access. This technique shows promise, especially for right internal carotid artery lesions.
Area of Science:
- Cardiovascular Interventions
- Vascular Surgery
- Interventional Radiology
Background:
- Carotid artery stenting (CAS) is a key treatment for internal carotid artery (ICA) revascularization.
- Femoral access for CAS is common but poses risks like access site complications and technical challenges.
- Transradial approaches for CAS are being explored as alternatives.
Purpose of the Study:
- To evaluate the feasibility of the contralateral transradial approach for carotid artery stenting (CAS).
Main Methods:
- Twenty patients with >80% carotid artery stenosis underwent CAS using a contralateral transradial approach.
- Catheters were guided via the contralateral radial artery to the external carotid artery, then advanced.
- A 6F Pinnacle Sheath was positioned in the distal common carotid artery for stenting.
Main Results:
- CAS was successful in 80% (16/20) of patients.
- 100% success was achieved for right carotid artery stenting (12/12), while 50% success for left (4/8).
- No radial access site complications occurred; one patient had a transient ischemic attack that resolved.
Conclusions:
- Contralateral transradial CAS is safe and technically feasible.
- This approach may be advantageous for patients with right ICA lesions due to favorable anatomy.
- It offers a viable alternative to traditional femoral access for CAS.
