Neurosurgical management of intracerebral hemorrhage (ICH) involves selective surgical intervention based on hemorrhage size, location, patient condition, and underlying etiology. Most small deep hemorrhages and lobar hemorrhages without rapid neurological deterioration or hydrocephalus initially receive medical treatment rather than surgery NICE NG128 Puissant & Ganti L 2026. Large hematomas causing significant mass effect with midline shift, rapid clinical deterioration, or brainstem compression typically require surgical evacuation and/or decompressive craniectomy NICE NG128 Puissant & Ganti L 2026.
Surgical options include:
- Open craniotomy and hematoma evacuation: the traditional standard for large or superficial hemorrhages, especially in cases with significant mass effect, provided adequate anticoagulation reversal and patient stability are achieved Grover and Ding Y. 2025,NICE NG128 Grover & Ding Y 2025 Puissant & Ganti L 2026.
- Minimally invasive surgery (MIS): emerging as a promising alternative to open surgery, MIS aims to evacuate hematomas with less iatrogenic injury to surrounding brain tissue. Recent randomized trials (e.g., MISTIE III) demonstrated feasibility and potential mortality benefit in select patients with supratentorial ICH volumes >20mL and moderate Glasgow Coma Scale (GCS) scores (5-12) Grover and Ding Y. 2025 Morris et al. 2024 Puissant & Ganti L 2026. The timing of MIS, especially in anticoagulated patients, depends crucially on rapid reversal of anticoagulation; once achieved, anticoagulation per se should not exclude surgery Grover and Ding Y. 2025.
- Decompressive craniectomy: considered for cases with refractory elevated intracranial pressure (ICP), malignant edema, or brain herniation. It may be performed within 48 hours of onset in patients with severe neurological deficits, and its risks and benefits should be discussed with the patient/family NICE NG128 Puissant & Ganti L 2026.
- External ventricular drainage (EVD): used for managing elevated ICP caused by obstructive hydrocephalus from intraventricular hemorrhage (IVH) or acute hydrocephalus, which may accompany ICH NICE NG228 Boulouis et al. 2026 Puissant & Ganti L 2026.
Special considerations include:
- Anticoagulation reversal: Rapid reversal of anticoagulants is critical before surgery to reduce hematoma expansion and improve outcomes. Vitamin K antagonists are reversed using vitamin K and 4-factor prothrombin complex concentrates (PCCs), while direct oral anticoagulants require specific reversal agents such as idarucizumab for dabigatran or PCCs for factor Xa inhibitors, if specific agents like andexanet alfa are unavailable or contraindicated Grover and Ding Y. 2025,Puissant and Ganti L. 2026 Grover & Ding Y 2025 Puissant & Ganti L 2026.
- Timing of surgery: Early surgical consultation and timely intervention improve outcomes for patients with large hematomas or deteriorating neurological status. Surgical evacuation is more beneficial when performed promptly, especially before irreversible secondary brain injury from mass effect occurs NICE NG128,Grover and Ding Y. 2025 Puissant & Ganti L 2026 Grover & Ding Y 2025.
- Posterior fossa hemorrhage: surgical intervention is recommended for cerebellar hematomas ≥15 mL causing neurological deterioration or brainstem compression due to the critical nature of this location NICE NG128 Puissant & Ganti L 2026.
- Neurosurgical decision-making in children: Pediatric intracerebral hemorrhage requires early interdisciplinary input with specialized imaging and neurosurgical evaluation. Hematoma evacuation, external ventricular drainage, and decompressive craniectomy are performed in children with neurological deterioration, mass effect, or hydrocephalus, guided by multidisciplinary consensus and adapted to underlying causes such as vascular malformations Boulouis et al. 2026 Boulouis et al. 2026.
Summary: The neurosurgical approach to ICH focuses on selective intervention for large, superficial, or life-threatening hemorrhages, balancing risks of surgery against patient stability and hematoma characteristics. Minimally invasive techniques are increasingly supported by emerging evidence, especially in anticoagulated patients after adequate reversal. Neurosurgical care includes hematoma evacuation, decompressive craniectomy, and cerebrospinal fluid diversion when indicated, delivered as part of multidisciplinary care with rapid anticoagulation reversal and careful monitoring NICE NG128,Grover and Ding Y. 2025,Boulouis et al. 2026 Puissant & Ganti L 2026 Grover & Ding Y 2025 Boulouis et al. 2026.
