National and international guidelines recommend surgical treatment (CEA) within this timeframe; however, no studies have specifically evaluated the optimal timing for CEA after TIA or minor stroke.\n\nIt is well established that the risk of a major stroke is highest in the first few days following a transient ischemic attack or minor stroke and then decreases over the subsequent days and weeks. This raises the hypothesis that performing an urgent carotid endarterectomy (within 3 days) may provide greater benefit compared to a delayed procedure (between 4 and 15 days).\n\nStudy Objectives\n\nPrimary Endpoint\n\nTo demonstrate that CEA for symptomatic ICA stenosis of 50% or greater (NASCET criteria) performed urgently within 72 hours of the onset of the ischemic symptom (TIA or minor stroke) is more effective than delayed CEA (performed after 72 hours but within 15 days) in reducing the risk of death, any type of stroke, and myocardial infarction within 90 days of the ischemic event.\n\nSecondary Endpoints\n\nTo demonstrate that urgent CEA (within 72 hours of symptom onset) is more effective than delayed CEA (after 72 hours but within 15 days) in reducing the risk of ipsilateral ischemic stroke within 90 days of the ischemic event.\n\nTo identify potential subgroups of patients who benefit more from urgent CEA compared to delayed CEA.\n\nTo demonstrate that urgent CEA (within 72 hours) is as safe as delayed CEA (after 72 hours) in terms of the risk of cerebral hemorrhagic complications.\n\nStudy Design\n\nThis is a prospective, randomized, multicenter, controlled, non-profit interventional study with blinded follow-up at 90 days by the neurologist/internist investigator. The study is coordinated by the Vascular Surgery Unit (UOC) at San Giovanni di Dio Hospital, USL TOSCANA CENTRO, in collaboration with the Vascular Surgery Units listed above. All patients treated at the participating centers are eligible for inclusion if they meet the inclusion and exclusion criteria and provide informed consent to participate in the study.\n\nThe study does not introduce modifications or conflicts with standard clinical practice, as all enrolled and randomized patients (whether within or after 72 hours) will undergo surgical treatment (CEA) within 15 days of the index symptom, in accordance with national and international guidelines.\n\nStudy Population\n\nNumber of patients to be enrolled: 456\n\nWithdrawal Criteria Patients may withdraw from the study at any time.\n\nInterventions\n\nThe study will evaluate the same surgical procedure, carotid endarterectomy (CEA), which involves the removal of the atherosclerotic plaque causing thromboembolism or hemodynamically significant stenosis. This will be performed in two different timeframes:\n\nWithin 72 hours of the ischemic symptom. Between 72 hours and 14 days after the symptom.\n\nThe two study groups will not differ in the type of treatment offered but only in the timing of its execution.\n\nNo experimental procedures will be conducted. Whether CEA is performed within 72 hours or after this period, the surgical procedure will adhere fully to the current guidelines.\n\nAssessment of Potential Benefit/Risk for the Study Population\n\nThe morbidity and mortality risk for the study participants is expected to be within the 6% limit for stroke/mortality at 30 days, as defined by the safety threshold in the literature and by national and international guidelines.\n\nIf this threshold (stroke/mortality at 30 days ≥ 6%) is exceeded in either group, the study will be terminated for safety reasons.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '90 Years', 'minimumAge': '45 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Eligibility Criteria\n\nInclusion Criteria:\n\nPatients presenting with the following characteristics:\n\nDe novo stenosis of the carotid bifurcation and/or internal carotid artery origin, equal to or greater than 50% (NASCET method), diagnosed by color Doppler ultrasound, MR angiography (MRA), CT angiography (CTA), or catheter angiography.\n\nTIA or minor ischemic stroke (NIHSS ≤ 5) ipsilateral to the carotid stenosis, occurring within the previous 24 hours.\n\nPreserved consciousness and neurologically stable symptoms.
