Abstract

Objective: Middle meningeal artery embolization (MMAE) has emerged as an effective minimally invasive treatment for chronic subdural hematoma (CSDH). Although the transradial approach (TRA) is increasingly used in neuroendovascular procedures, evidence regarding its feasibility for MMAE using a 4-Fr diagnostic catheter as a guiding system remains limited.
