Carotid arterial stenting

Carotid arterial stenting (CAS) is a minimally invasive endovascular interventional procedure that can potentially offer the same advantage as surgery (carotid endarterectomy).

Indications for carotid stenting are evolving with endarterectomy trials that evaluate the carotid stenosis cutoff values for treatment. Currently, the indications include:

  • symptomatic patients with ≥70% stenosis (NASCET trial)
  • asymptomatic patients with >60% stenosis (ACAS study) 
  • symptomatic patients with stenosis of at least 50-69% stenosis
  • complete carotid occlusion
  • major disabling stroke on the ipsilateral side/disabling dementia
  • intracranial tumour/haemorrhage
  • thick calcification at the site of carotid stenosis

The first percutaneous transluminal carotid angioplasty (PTA) was performed by Charles Kerber in 1980 5
