Infratentorial Intracerebral Hemorrhage

Area of Science:

• Neurology
• Neurosurgery
• Clinical Trials

Background:

• Infratentorial intracerebral hemorrhage (ICH) is associated with poor outcomes.
• Location-specific analysis (cerebellar vs. brain stem) of infratentorial ICH is limited.
• The INTERACT 1 and 2 trials provide a dataset for evaluating these differences.

Purpose of the Study:

• To compare the clinical characteristics and outcomes of brain stem ICH versus cerebellar ICH.
• To evaluate the relationship between location and prognosis in infratentorial ICH.
• To assess mortality and quality of life differences between the two locations.

Main Methods:

• Retrospective analysis of 195 patients from the INTERACT 1 and 2 trials.
• Comparison of patients with brain stem ICH and cerebellar ICH.
• Logistic regression models used to analyze outcomes: death, major disability, and quality of life (EQ-5D).

Main Results:

• Brain stem ICH patients were younger, less female, and had higher NIH Stroke Scale scores upon admission.
• Brain stem ICH had smaller volumes and less intraventricular extension compared to cerebellar ICH.
• Brain stem ICH was associated with significantly higher mortality (OR 37.1) and worse EQ-5D pain scores (OR 3.36).

Conclusions:

• Cerebellar and brain stem ICH exhibit distinct clinical profiles.
• Brain stem ICH is linked to a poorer prognosis, including higher fatality rates.
• Patients with brain stem ICH report worse quality of life, specifically in the pain domain.
