Summary
Transcarotid artery revascularization (TCAR) offers a safe hybrid approach for carotid stenosis management. This case study demonstrates TCAR
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Neurology
Background:
- Carotid stenosis management includes medical therapy, endarterectomy, and stenting.
- Transcarotid artery revascularization (TCAR) is a hybrid approach using surgical access for endovascular stenting.
- TCAR may offer lower risks of stroke and cranial nerve injury compared to other methods.
Purpose of the Study:
- To present a case of recurrent severe carotid stenosis managed with TCAR.
- To highlight the safety and efficacy of TCAR in a complex patient scenario.
Main Methods:
- Transcarotid artery revascularization (TCAR) procedure.
- Endovascular stent placement in the internal carotid artery via direct common carotid access.
- Utilized flow reversal technique for cerebral protection.
Main Results:
- Successful revascularization of 85% right internal carotid artery stenosis.
- Patient tolerated the TCAR procedure well.
- No adverse events reported during hospitalization or at 1-month follow-up.
Conclusions:
- TCAR is a viable and safe option for managing recurrent severe carotid stenosis.
- This case supports TCAR as an alternative to traditional methods, especially in patients with challenging anatomy or prior interventions.
