JAMA surgery·2015

Eversion carotid endarterectomy (CEA) is safe. Shunt use during CEA did not significantly increase stroke or death, indicating shunting is advisable for this procedure.

Area of Science:

  • Vascular Surgery
  • Cerebrovascular Surgery

Background:

  • Eversion carotid endarterectomy (CEA) is a recognized safe and effective procedure for carotid artery stenosis.
  • Concerns persist regarding the necessity and safety of shunt insertion during eversion CEA.

Purpose of the Study:

  • To evaluate the safety and impact of shunt insertion during eversion carotid endarterectomy.
  • To compare perioperative stroke, death, and recurrent stenosis rates in patients undergoing eversion CEA with and without shunting.

Main Methods:

  • A retrospective analysis of 624 primary eversion CEAs performed over 9 years.
  • Selective shunting was employed based on continuous electroencephalographic (EEG) monitoring for cerebral ischemia.
  • Patients were followed postoperatively with duplex ultrasound and clinical evaluations for up to 91 months.

Main Results:

  • No perioperative deaths occurred. The overall perioperative stroke rate was 0.6% (4/624).
  • One major stroke (2.3%) occurred in the shunted group (n=43), with no statistically significant difference compared to the non-shunted group.
  • No late recurrent stenosis (>50%) was observed; one late asymptomatic occlusive event occurred in the non-shunted group.

Conclusions:

  • Shunt insertion is a safe adjunct to eversion carotid endarterectomy.
  • Perioperative mortality and morbidity are not significantly altered by shunt use during eversion CEA.
