Summary
This study demonstrates a successful endovascular stent placement for cervical internal carotid artery stenosis using a novel right radial artery approach. This technique offers a viable alternative when traditional transfemoral access is compromised.
Area of Science:
- Vascular Surgery
- Interventional Neurology
- Endovascular Interventions
Background:
- Cervical internal carotid artery stenosis poses a significant risk of stroke.
- Traditional transfemoral access for endovascular revascularization can be challenging in patients with severe iliac artery atherosclerosis.
- Alternative access routes are crucial for expanding endovascular treatment options.
Observation:
- A 70-year-old male patient with arteriosclerosis obliterans required endovascular treatment for left internal carotid artery stenosis.
- Transfemoral access was precluded due to bilateral common iliac artery atherosclerosis.
- Access was successfully achieved via the proximal right radial artery.
Findings:
- A 6F short sheath was placed in the right radial artery.
- A guiding catheter was advanced to the left common carotid artery using a coaxial system.
- Successful endoluminal stent placement was achieved under distal protection.
Implications:
- The radial artery approach provides a feasible alternative for carotid artery stenting when transfemoral access is not possible.
- This technique expands the armamentarium for endovascular treatment of cerebrovascular disease.
- Consideration of the radial artery approach is recommended for challenging endovascular procedures involving carotid access.
