Traumatic Parafalcine Subdural Hematoma: A Clinically Benign Finding

Area of Science:

• Neurosurgery
• Trauma Care
• Radiology

Background:

• Current intracranial hemorrhage guidelines lack location-specific management strategies.
• Parafalcine subdural hematoma (SDH) may represent a distinct clinical entity compared to convexity SDH.
• The necessity of critical care monitoring and repeat imaging for parafalcine SDH is questioned.

Purpose of the Study:

• To investigate whether parafalcine SDH is a distinct clinical entity.
• To compare outcomes and resource utilization between parafalcine SDH and convexity SDH patients.
• To determine if parafalcine SDH patients benefit from intensive care unit (ICU) admission or repeat imaging.

Main Methods:

• Retrospective review of patients with isolated head injuries at a level I trauma center.
• Identification of 88 patients with parafalcine SDH and 228 with convexity SDH.
• Comparison of demographics, comorbidities, antiplatelet/anticoagulant use, radiographic progression, neurologic deterioration, neurosurgical intervention, mortality, and length of stay.

Main Results:

• Parafalcine SDH patients exhibited significantly lower radiographic progression and no instances of neurologic deterioration, neurosurgical intervention, or mortality compared to convexity SDH patients.
• Patients with parafalcine SDH admitted to the floor had a shorter length of stay than those admitted to the ICU, with no difference in outcomes.
• Demographics, comorbidities, and use of antiplatelet and anticoagulant agents were similar between the groups.

Conclusions:

• Parafalcine SDH represents a distinct and relatively benign clinical entity.
• Intensive care unit admission and repeat imaging are not beneficial for patients with parafalcine SDH.
• Management guidelines for intracranial hemorrhage should consider bleed location, specifically differentiating parafalcine SDH.
