Summary

Carotid endarterectomy is a safe surgical option for symptomatic carotid artery disease, with 96% of patients experiencing good outcomes. This procedure offers a lower risk than stroke for eligible patients.

Area of Science:

  • Vascular Surgery
  • Neurology
  • Cardiovascular Medicine

Background:

  • The number of carotid endarterectomies increased significantly between 1971 and 1987.
  • The procedure's safety, defined by combined morbidity and mortality below the 5% annual stroke risk, is crucial for its therapeutic consideration in symptomatic carotid artery disease.

Purpose of the Study:

  • To review the experience and outcomes of 891 carotid endarterectomies performed between January 1979 and June 1987.
  • To evaluate the safety and efficacy of carotid endarterectomy as a treatment for various presentations of carotid artery disease.

Main Methods:

  • A retrospective review of 891 patients undergoing carotid endarterectomy.
  • Patients were monitored under endotracheal anesthesia with continuous intra-arterial pressure, central venous pressure, and arterial blood gas monitoring.
  • Both conventional (open) and limited (closed) endarterectomy techniques were employed, with intraluminal shunts used in 2% of cases.

Main Results:

  • Overall mortality was 1%, with 3% experiencing persistent major neurological deficits and 3% having transient ischemic attacks (TIAs) that resolved.
  • Of patients with preoperative neurological deficits, 4% recovered.
  • At one month post-surgery, 96% of patients were in the same or better condition compared to their preoperative state.

Conclusions:

  • Carotid endarterectomy, when performed with careful monitoring and appropriate technique, demonstrates a favorable safety profile.
  • The study supports carotid endarterectomy as a viable therapeutic option, with a high percentage of patients achieving positive or neutral outcomes.
  • The overall complication rate is below the annual risk of stroke for patients with symptomatic carotid artery disease, validating its use.
