Predicting brain swelling after stroke treatment

Early Identification of Malignant Brain Edema in laRge Artery oCclusive Stroke After Endovascular Therapy (EMBRACE Study)

Observational Zhejiang Provincial People's Hospital · NCT06451887

This study is testing a new way to predict which stroke patients are at risk for dangerous brain swelling after a specific treatment to help doctors make better decisions for their care.

What this trial studies

This study aims to design and validate a predictive model for malignant brain edema (MBE) following endovascular thrombectomy (EVT) in patients with acute large vessel occlusion stroke. By identifying high-risk patients for MBE, clinicians can make informed decisions regarding triage and early interventions, potentially improving patient outcomes. The study will analyze various predictive factors, including clinical and radiological indicators, to enhance the accuracy of early predictions for MBE. The ultimate goal is to reduce morbidity and mortality associated with this severe complication of stroke treatment.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who have experienced an ischemic stroke and are undergoing endovascular thrombectomy within 24 hours of symptom onset.

Not a fit: Patients with posterior circulation occlusion or those with severe comorbidities that limit their expected survival may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved patient outcomes by enabling timely interventions for those at high risk of malignant brain edema.

How similar studies have performed: Previous studies have shown promise in identifying predictive factors for malignant brain edema, suggesting that this approach may yield valuable insights.
