Is a stent always safer than surgery for carotid narrowing?

First ask whether intervention is needed

Carotid plaque may restrict blood flow to the brain. Plaque or clot fragments can also travel into brain vessels and cause a stroke. Treatment discussions aim to reduce these risks, rather than make every narrowed artery look equally wide.[1]

Endarterectomy removes plaque through neck surgery; a stent holds the narrowed artery open. The former involves an incision and risks to nearby nerves, while the latter still requires consideration of fragments entering brain vessels during the procedure.[1,2] Avoiding a large incision does not remove that concern.

A Chinese case shows why location changes the choice

A case published by Beijing Tiantan Hospital in 2025 involved a 74-year-old patient with worsening right internal carotid narrowing. Vessel tortuosity made a protection device difficult to position for conventional stenting, while a high lesion made conventional endarterectomy difficult.[3]

The issue was not simply whether the patient preferred an operation. Each route had a different anatomical obstacle. The case does not mean another person of the same age or with similar narrowing is suitable for the same approach.

The team used transcarotid artery revascularization, or TCAR. In the reported procedure, the artery was accessed through the neck and a flow-reversal protection circuit established before stent placement.[3] It still involved a neck incision and a stent; it should not be treated as identical to conventional access through the femoral artery.

A new route still involves trade-offs

The Tiantan report explicitly discusses cerebral embolism, hyperperfusion syndrome and bleeding at the neck incision. Short-term neurological examination showed no obvious abnormality, but long-term follow-up was not reported.[3] This documents an individualized procedure performed in China, not superiority for everyone or guaranteed current availability for foreign patients.

Endarterectomy also carries risks including stroke, bleeding, infection and nerve injury, and narrowing can recur.[2] Ask where your main risk comes from, which risk the proposed operation aims to reduce and what new risks it introduces.

What should specialist assessment explain?

Relate questions to your images: where is the narrowing, have there been related ischemic symptoms, why is intervention proposed, and what obstacles affect conventional stenting and endarterectomy? If TCAR is recommended, what is the specific reason and what alternatives remain?

For a second opinion in China, organize previous images and treatment records using the medical records and imaging guide. SinoCareHub can help prepare questions and interpreting; doctors determine suitability and procedure. Sudden one-sided weakness, speech difficulty or visual changes need immediate emergency care where you are, not a wait for an overseas assessment.[2]
