Dynamic Changes in Endothelial Glycocalyx and Inflammatory Response in Patients with Acute Ischemic Stroke Treated with Mechanical Thrombectomy: Pathophysiological Aspects and Clinical Implications.

Acute ischemic stroke (AIS) is characterized by complex interactions among vascular occlusion, endothelial injury, and inflammatory activation, which collectively influence clinical outcomes. Increasing attention has focused on the endothelial glycocalyx, a critical regulator of vascular permeability, mechanotransduction, and inflammatory signaling. Disruption of the endothelial glycocalyx during ischemia and subsequent reperfusion contributes to blood-brain barrier (BBB) dysfunction and secondary brain injury. Mechanical thrombectomy has emerged as the reference standard treatment for large vessel occlusion in AIS. This review synthesizes current evidence on endothelial glycocalyx degradation and associated inflammatory cascades in cute ischemic stroke, with particular emphasis on patients undergoing mechanical thrombectomy. We examine the mechanisms underlying endothelial and BBB injury, ischemia-reperfusion-mediated vascular dysfunction, and systemic inflammatory responses (SIRS). In addition, the potential clinical relevance of circulating biomarkers indicative of endothelial glycocalyx shedding and endothelial damage is discussed. By integrating molecular pathophysiology with contemporary reperfusion strategies, this review highlights the importance of endothelial protection as a potential adjunct to mechanical thrombectomy. While mechanical thrombectomy remains the gold standard therapy for AIS due to large vessel occlusion, targeting endothelial glycocalyx integrity and post-reperfusion inflammation may represent a promising approach to optimizing neurological outcomes and reducing complications. Further research is required to elucidate specific pathophysiological mechanisms and to develop targeted therapeutic strategies aimed at reducing stroke-related morbidity and mortality.
