BACKGROUND: The impact of carotid endarterectomy (CEA) on symptomatic patients with mild high-risk carotid stenosis has not been really investigated and it is not well-defined. This multicenter retrospective study aims to assess the safety and effectiveness of CEA in patients with 50% or less stenosis with symptoms despite best medical therapy.
METHODS: Between January 2018 and December 2024, all consecutive patients presenting with carotid-related neurological symptoms and a ≤50% high risk carotid stenosis submitted to CEA in eight high-volume vascular centers were included in the present study. All patients underwent duplex ultrasonography and computed tomography angiography to identify plaque morphological features. All patients were checked for alternative possible source of brain embolism.
RESULTS: Twenty-nine patients with high-risk embolic plaques determining ≤50% stenosis and carotid-related neurological symptoms underwent CEA. The majority of plaques were Gray-Weale 1 or 2 (79.3%) and with ulcerated cap (79.3%). Symptoms reported at onset and during hospitalization up to CEA were 8 (27.5%) TIA, 8 (27.5%) crescendo TIA, 10 (34.4%) minor strokes, 3 (34.4%) strokes in evolution. Ischemic brain lesions of less of 25 mm were detected in 12 patients (41.3%). No perioperative stroke, death, myocardial infarction or cerebral hemorrhage occurred in this series. Only one TIA was detected due to a surgical defect that was promptly corrected. No patient experienced recurrent neurologic events related to the revascularized hemisphere during follow-up (mean 35.6 months).
CONCLUSIONS: Despite the limited number of patients included in the study, CEA has been shown to be safe and effective in preventing recurrent neurological ischemic events in highly selected patients with mild carotid high-embolic-risk plaque stenosis treated at high-volume institutions. Further studies are required to identify the most appropriate diagnostic tools and the precise carotid plaque features associated with high-embolic risk.
