Carotid Stenting

Carotid Stenting

What is a Carotid artery Stenting procedure?

CAS is a minimally invasive procedure used to treat carotid artery stenosis, a condition that’s characterized by plaque buildup in the carotid arteries. The carotid arteries are major blood vessels located on either side of your neck that supply blood to your brain. During CAS, a stent (metal tube) is placed inside the carotid artery to keep it open so that blood can flow more easily without any obstruction.


Key benefits of CAS

  • CAS is considered a less invasive option with a faster recovery time than carotid endarterectomy (CEA), the traditional surgery for carotid artery stenosis.
  • CAS may reduce the risk of stroke by improving blood flow to the brain and preventing clots from forming or breaking off from the plaque.
  • CAS may be suitable for patients who have contraindications to CEA, such as previous neck surgery or radiation, severe cardiac or pulmonary disease, or difficult anatomy.
  • CAS may be performed under local anesthesia with sedation, which may reduce the risk of complications from general anesthesia.


Key features of CAS


  • CAS involves the use of a catheter, a long thin tube, that is inserted through a small incision in the groin and guided to the carotid artery using X-ray imaging.
  • CAS uses a device called an embolic protection device (EPD), which is a filter or a balloon that is placed beyond the plaque to catch any debris that may break off during the procedure and prevent them from reaching the brain.
  • CAS uses a balloon to dilate the narrowed part of the artery and a stent to support the arterial wall and prevent it from collapsing or restenosing.
  • CAS may be performed using different approaches, such as trans-femoral, trans-brachial, or trans-carotid, depending on the anatomy and preference of the operator


How CAS addresses customer pain points


  • CAS may address the pain point of having a high risk of stroke due to carotid artery stenosis by offering a safe and effective alternative to CEA.
  • CAS may address the pain point of having a long and painful recovery after CEA by offering a shorter and less traumatic procedure with less scarring and bleeding.
  • CAS may address the pain point of having limited options for treatment due to medical or anatomical factors by offering a more flexible and adaptable procedure that can accommodate different patient profiles
