Overview

Randomized trial assesses the risk of stroke in patients with retinal or cerebral events due to carotid stenosis, highlighting distinct risk profiles.

Key Points

  • This study aims to evaluate the risk of recurrent ischemic stroke and perioperative complications in patients with retinal artery occlusion compared to other presenting events.
  • Analyzed 927 patients with ≥50% symptomatic carotid stenosis from three cohorts.
  • Compared preoperative ischemic stroke risk and 30-day postoperative outcomes among RAO, AFX, TIA, and stroke.
  • Data were collected on the presenting events and subsequent complications.
  • The 30-day risk of perioperative stroke/death was 1.4% for retinal events compared to 5.8% for cerebral events (P = 0.027).
  • The preoperative ischemic stroke risk was low and similar for AFX (2.1%) and RAO (0%) with P = 1.0.
  • Overall, RAO showed similarly low risks for preoperative ischemic stroke and perioperative complications as AFX.
