Clinical Trial Summary

To design and validate a predictive model for malignant brain edema after endovascular thrombectomy.

Clinical Trial Description

Stroke is a significant global cause of death and disability. Endovascular thrombectomy (EVT) is currently the best treatment for acute large vessel occlusion stroke (ALVOS), as it can greatly reduce mortality and improve patient outcomes. However, only half of patients who undergo EVT achieve functional independence, and malignant brain edema (MBE), a severe complication, can occur after the procedure, leading to a poor prognosis. Previous studies have confirmed the effectiveness of early decompressive hemicraniectomy in reducing morbidity and mortality in patients with malignant brain edema. Therefore, identifying high-risk patients for MBE can help clinicians make appropriate triage and early intervention decisions, potentially saving patients' lives.

Predictive factors for post-ischemic stroke brain edema have been widely discussed, and reliable early predictive indicators have been identified, such as age, early consciousness disorders, baseline National Institutes of Health Stroke Scale (NIHSS), atrial fibrillation, hypertension, baseline blood glucose, and the level of reperfusion after EVT. Radiological factors, such as the Alberta Stroke Program Early CT Score (ASPECTS), collateral circulation rating of arteries, venous outflow status, CT perfusion core infarct volume, perfusion-based collateral status, and clot burden, are closely associated with the occurrence of MBE post-EVT. However, due to individual differences and multiple factors affecting MBE, a single factor cannot effectively predict MBE. Establishing a clinical risk prediction model can effectively identify high-risk populations for MBE at an early stage. ;
