Insights
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.
Abstract:
We described a case of endoluminal stent placement for cervical internal carotid artery stenosis in which access was obtained via the proximal portion of the right radial artery. A 70-year-old man with a history of arteriosclerosis obliterans presented for endoluminal revascularization of a stenosed left internal carotid artery. The transfemoral approach was not possible because of severe atherosclerosis of the bilateral common iliac arteries. An approach was attempted via the right radial artery. After placement of a 6F short sheath in the proximal portion of the right radial artery, the guiding catheter was positioned in the left common carotid artery using the coaxial catheter system. Stenting was successfully performed under distal protection. This novel approach should be considered for endovascular procedures for which access to the carotid artery is limited.
