Core Tip
Core Tip: This case demonstrates a refined layered embolization technique as a novel approach for treating chronic subdural hematoma with significant mass effect. By employing sequential low- and standard-concentration embolic suspensions, the technique achieves deep distal penetration and proximal sealing, facilitating complete hematoma clearance within three months. This approach expands the therapeutic role of middle meningeal artery embolization to high-risk or surgically unsuitable patients.
