Acute interhemispheric subdural hematomas. Report of nine cases

Area of Science:

• Neurosurgery
• Trauma Surgery
• Neurology

Background:

• Acute interhemispheric subdural hematoma (ISH) is a critical condition often resulting from trauma.
• Understanding the presentation, prognosis, and progression of ISH is crucial for effective patient management.

Observation:

• This study presents nine male patients with acute ISH, all with trauma as the etiology.
• Prognosis was poor for young adults and a child due to severe clinical presentation and high mortality.
• Asymptomatic patients were managed conservatively.

Findings:

• Acute ISH occurs across all age groups, from infants (shaken baby syndrome) to elderly patients on anticoagulants.
• Acute ISH does not appear to progress into chronic convexity subdural hematoma (SH); they may coexist simultaneously.
• Mortality rates for ISH and acute SH are comparable in patients with similar neurological status.

Implications:

• The findings challenge previous assumptions about ISH progression and mortality.
• This research highlights the diverse demographic affected by ISH and emphasizes the need for tailored treatment strategies.
• Further investigation into the specific mechanisms and outcomes of ISH in different age groups is warranted.
