Letter to the editor: "Therapeutic efficacy of drilling drainage combined with intraoperative middle meningeal artery occlusion in the management of chronic subdural hematoma: a clinical study".

This letter addresses the research presented by Sun et al. on the integration of digital subtraction angiography (DSA) with conventional surgical drainage for chronic subdural hematoma (CSDH), focusing on precision in targeting the middle meningeal artery (MMA). The study demonstrates a reduction in hematoma recurrence and drainage tube indwelling times, highlighting the procedural benefits without added complications. The letter suggests further research directions, including the potential for personalized surgical approaches based on MMA anatomy variations, and emphasizes the importance of this technique in enhancing neurosurgical outcomes.
