Medical management of haemorrhagic stroke

Area of Science:

• Neurology
• Neurosurgery
• Public Health

Background:

• Intracerebral haemorrhage (ICH) accounts for 15% of strokes but carries a significantly worse prognosis.
• ICH incidence is higher in Asian populations, potentially due to increased rates of small vessel disease, hypertension, and genetic factors.
• Overall ICH mortality approaches 50%, with limited effective treatments beyond stroke unit care.

Purpose of the Study:

• To review the current understanding and management of intracerebral haemorrhage.
• To discuss the efficacy and controversies surrounding surgical and medical interventions for ICH.
• To highlight the challenges in managing acute hypertension in ICH patients.

Main Methods:

• Review of existing literature and clinical trial data on intracerebral haemorrhage.
• Analysis of prognostic factors and epidemiological data, including ethnic variations.
• Evaluation of the evidence for surgical and medical treatments, including corticosteroids, glycerol, and mannitol.

Main Results:

• A large trial found no benefit from surgery for supratentorial ICH, though it remains important for cerebellar ICH.
• Medical therapies like glycerol and mannitol for brain edema and intracranial pressure lack proven value.
• Corticosteroids are contraindicated in ICH and may worsen outcomes; management of acute hypertension is controversial and evidence-based guidelines are lacking.

Conclusions:

• Intracerebral haemorrhage presents a significant challenge with high mortality and limited effective treatments.
• Current evidence does not support routine surgery for supratentorial ICH or the use of specific medical therapies.
• Further research is needed to establish effective treatments and evidence-based guidelines for managing ICH and associated hypertension.
