Carotid stenting with embolic protection (CAS) appears equivalent to carotid endarterectomy (CEA) for treating carotid artery disease. The CaRESS Phase I trial suggests similar outcomes for mortality and stroke in a broad patient population.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Clinical Trials

Background:

  • Carotid artery disease poses a significant risk for stroke.
  • Carotid endarterectomy (CEA) is a standard treatment.
  • Carotid stenting with distal embolic protection (CAS) offers a less invasive alternative.

Purpose of the Study:

  • To determine the sample size for comparing CAS and CEA equivalence.
  • To evaluate the safety and efficacy of CAS versus CEA in a broad-risk population.
  • To assess combined endpoints of mortality and stroke.

Main Methods:

  • CaRESS Phase I trial enrolled 397 patients across 14 centers.
  • Patients with symptomatic and asymptomatic carotid artery disease were included.
  • Primary endpoint: combined all-cause mortality and stroke at 30 days and 1 year.

Main Results:

  • The study successfully mirrored real-world clinical practice.
  • Results indicate potential equivalence between CAS and CEA treatments.
  • No significant differences in primary endpoints were observed between groups.

Conclusions:

  • Carotid stenting with distal embolic protection (CAS) demonstrates comparable outcomes to carotid endarterectomy (CEA).
  • The CaRESS Phase I trial provides valuable data for future definitive studies.
  • Equivalence suggests CAS is a viable treatment option for carotid artery disease.
