    Delving Deeper into the Correlation between Liquid Embolic Surface Area and Chronic Subdural Hematoma Resolution in Middle Meningeal Artery Embolization

    Dear Editor,
    I would like to commend the authors for their insightful study titled "Liquid embolic surface area as a predictor of chronic subdural hematoma resolution in middle meningeal artery embolization" [1]. The investigation into the correlation between liquid embolic surface area (LEA SA) and chronic subdural hematoma (cSDH) resolution in the context of middle meningeal artery embolization (MMAE) presents valuable contributions to the field. The authors employed a meticulous approach, retrospectively collecting data from 74 patients who underwent first-line MMAE with ethylene vinyl alcohol (EVOH) and utilizing 3D segmentation to quantify LEA SA. The observed correlation between greater LEA SA and enhanced cSDH resolution rates at 3 months and 6 months post-embolization is a noteworthy contribution to the field.
    The study's strength lies in its unique focus on a patient group undergoing first-line MMAE for cSDH, a subset that has been relatively underrepresented in the existing literature. The authors rightly acknowledge the potential selection bias in this group, considering patients with greater midline shift or poor neurologic exams might be directed immediately to surgical treatment. Nonetheless, the results support the utilization of upfront MMAE in patients with riskier surgical profiles due to comorbidities or borderline radiographic and clinical features.
    However, it is essential to scrutinize the limitations outlined by the a...
