New horizons in subdural haematoma

Area of Science:

• Neurology
• Geriatrics
• Neurosurgery

Background:

• Subdural hematoma (SDH) is common in frail older adults, often resulting from falls.
• Anticoagulant and antiplatelet use in SDH patients presents complex risks of rebleeding and thrombosis.
• Current UK management of SDH is inconsistent, lacking established guidelines.

Purpose of the Study:

• To review current decision-making processes for managing subdural hematoma in older adults with frailty and multimorbidity.
• To evaluate the safety and efficacy of different interventions for acute and chronic SDH in this population.
• To identify gaps in evidence and guide future research for improved SDH management.

Main Methods:

• Review of existing literature on subdural hematoma epidemiology, risk factors, and management strategies in older adults.
• Analysis of outcomes associated with surgical decompression, burr hole drainage, and middle meningeal artery embolisation.
• Assessment of current clinical practices and guideline deficiencies in the UK.

Main Results:

• Surgical decompression for acute SDH has poor outcomes in older adults.
• Burr hole drainage is a potentially safe and effective option for symptomatic chronic SDH (cSDH).
• Middle meningeal artery embolisation shows promise as a minimally invasive option to reduce rebleeding risk.

Conclusions:

• Careful patient assessment is crucial to differentiate cSDH symptoms from other medical conditions.
• Evidence-based guidelines are needed to standardize and optimize SDH management in frail older populations.
• Further randomized controlled trials are essential to inform clinical practice beyond historical observational data.
