These interventions have proven effective in preventing ischemic stroke in patients with hemodynamically significant carotid artery stenoses. However, even following a technically successful procedure, the risk of perioperative ischemic brain injury persists. According to meta-analyses, one in five patients exhibits covert (\"silent\") strokes after reconstructive interventions, with their frequency being ten times higher than that of clinically manifest events. Such lesions are associated with cognitive decline and an increased risk of dementia. An additional risk factor is the \"no-reflow\" phenomenon-an impairment of microcirculatory reperfusion that occurs even after the restoration of macrovascular blood flow, thereby limiting the effectiveness of surgical revascularization.\n\nCognitive disorders and postoperative delirium, observed in 15-30% of patients after CEA, adversely affect rehabilitation and long-term prognosis. To date, there are no reliable pharmacological strategies to prevent these complications.\n\nIn this context, inert gases have attracted significant interest as potential neuroprotective agents. Xenon, despite its proven efficacy, is limited by high cost and challenges in industrial production. Argon, in contrast, is accessible, safe, and technologically straightforward to administer. In preclinical models of stroke and ischemia-reperfusion, argon has demonstrated pronounced anti-apoptotic, anti-inflammatory, and antioxidant effects, mediated through the regulation of TLR2\u002F4-, ERK1\u002F2-, Nrf2-, and NF-κB-dependent signaling pathways. Its ability to suppress microglial activation towards the M1 phenotype and inhibit the NLRP3 inflammasome has been noted, which reduces neuroinflammation and decreases the volume of secondary neuronal damage. Short-term argon inhalation in healthy volunteers has shown a favorable safety profile with no adverse effects on cerebral hemodynamics.\n\nThus, it is highly relevant to clinically test the hypothesis that perioperative inhalation of an argon-containing gas mixture can reduce the incidence of ischemic brain injuries and cognitive impairments in patients undergoing CEA.",[26,27],"Carotid Artery Disease","Carotid Artery Stenoses",[29,30,31,32,33,34,35,36,37],"Carotid artery disease","Carotid artery stenosis","Carotid artery surgery","Neurocognitive disorders","postoperative delirium","Stroke","Neuroinflammation","Argon","Organ protection","RECRUITING","2026-06-16",{"date":41,"type":42},"2026-06-18","ACTUAL",{"date":44,"type":42},"2025-09-22",{"date":46,"type":20},"2026-11-01",{"name":48,"class":49},"Negovsky Reanimatology Research Institute","OTHER_GOV",{"id":51,"slug":52,"hasResults":11,"nctId":53,"briefTitle":54,"officialTitle":55,"acronym":56,"eligibilityCriteria":57,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":4,"enrollmentInfo":58,"targetDuration":4,"studyType":21,"phases":60,"briefSummary":62,"conditions":63,"keywords":65,"overallStatus":71,"whyStopped":4,"lastUpdateSubmitDate":72,"lastUpdatePostDateStruct":73,"startDateStruct":75,"completionDateStruct":77,"leadSponsor":79,"locationsCount":82},"100597872","improved-medication-and-care-to-achieve-lipid-targets-after-carotid-surgery-100597872","NCT07064135","Improved Medication and Care to Achieve Lipid Targets After Carotid Surgery","Impact of Prompt Medication Adjustment and Intensive Follow-up on Achieving Lipid Targets in Patients Undergoing Carotid Endarterectomy","IMACS","Inclusion Criteria:\n\n* Age \\>17 years\n* Diagnosed carotid artery stenosis\n* Planned carotid endarterectomy\n* LDL cholesterol \\>55 mg\u002FdL\n* Willingness to participate, documented by written informed consent\n\nExclusion Criteria:\n\n* Ongoing treatment with PCSK9 inhibitors\n* Carotid surgery for reasons other than stenosis (e.g., traumatic injury)",{"count":59,"type":20},50,[61],"NA","The goal of this clinical trial is to find out if patients who receive extra support stay on their cholesterol-lowering therapy and therefore have lower cholesterol levels after 4 months.
