Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Neurology

Background:

  • Carotid endarterectomy has been the standard for stroke prevention in carotid bifurcation disease for 50 years.
  • Carotid stenting has emerged as a viable surgical alternative over the past decade.
  • Filter embolic protection devices enhance the safety of carotid stenting.

Purpose of the Study:

  • To evaluate the efficacy of carotid stenting compared to endarterectomy in high-risk patients.
  • To discuss the implications of FDA approval and future challenges for carotid stenting.

Main Methods:

  • Randomized controlled trial (Stenting and Angioplasty with Protection in Patients at High Risk for Endarterectomy [SAPPHIRE]).
  • Registry data (ACCULINK for Revascularization of Carotids in High Risk Patients [ARCHeR], Registry Study to evaluate the Neuroshield Bare-Wire Cerebral Protection System and X-Act Stent in patients at high risk for Carotid Endarterectomy [SECuRITY]).

Main Results:

  • Carotid stenting compared favorably to endarterectomy in high-risk patients.
  • High-risk conditions include cardiac, pulmonary, renal disease, prior neck surgery, radiation, or difficult anatomy.

Conclusions:

  • FDA approval of carotid stenting is anticipated, offering a new therapeutic option.
  • Challenges include restricted reimbursement, the need for a national coverage decision, and limited expertise requiring tailored training across specialties.
