One-Stage Burr Hole Surgery and Middle Meningeal Arterial Embolization for Treating Chronic Subdural Hematoma in a Hybrid Operative Angiography Suite

Background: Chronic subdural hematoma (CSDH) is a prevalent neurosurgical condition that is known to recur and that leads to unfavorable clinical outcomes. Middle meningeal artery embolization (MMAE) has emerged as an alternative treatment to prevent recurrence. This study investigated the efficacy of combined 2 therapies in a hybrid operative suite for high-risk patients. Methods: This retrospective review provides evidence for the indications and benefits of one-stage combined therapy in a hybrid neurovascular operative suite. The procedures include burr hole craniostomy, irrigation, and drainage followed by adjuvant MMAE at the lesion site. Subsequently, routine cone beam computed tomography is conducted after the whole process. Results: Five patients with symptomatic CSDH and mass effect were enrolled in this study. Among them, 3 patients had undergone burr hole surgery previously but experienced hematoma recurrence. Two patients presented with a history of recent cardiac stent placement due to coronary artery disease, precluding the cessation of antiplatelet or anticoagulant therapy. All patients experienced symptom resolution and demonstrated no evidence of CSDH recurrence during the follow-up period. Conclusions: In our initial case experiences, one-stage burr hole surgery and adjuvant MMAE for treating chronic subdural hematoma in a hybrid operative angiography suite could be a feasible and effective treatment modality.
