Overview
Acute nontraumatic intracranial subdural hematoma (aSDH) is a serious neurological emergency characterized by bleeding between the dura mater and arachnoid mater, often leading to increased intracranial pressure and neurological deficits 1.Diagnosis
Clinical Presentation: Altered mental status, focal neurological deficits, headache 1.
Imaging: CT scan is essential for diagnosis, showing crescent-shaped hyperdense collections over cerebral convexity 1.
Grading: Not explicitly detailed in the abstract, but clinical grading systems like the Hunt and Hess scale can be applied 1.Management
Surgical Interventions: Emergency decompressive craniectomy (DC) and craniotomy (CO) are primary treatments for evacuation 1.
Timing: Procedures typically performed within 4 hours of hospital arrival 1.
Outcome: High in-hospital mortality observed regardless of the surgical procedure (DC vs CO) 1.Special Populations
No Specific Details Provided: The abstracts do not provide specific guidance or outcomes related to pregnancy, pediatrics, elderly patients, or comorbidities 1.Key Recommendations
Emergency Surgical Evacuation: Perform emergency decompressive craniectomy or craniotomy for acute subdural hematoma within 4 hours of presentation to manage intracranial pressure (Evidence: Moderate) 1.
No Clear Procedure Preference: There is no significant difference in mortality outcomes between decompressive craniectomy and craniotomy; choice may depend on surgeon preference and institutional expertise (Evidence: Moderate) 1.
High Mortality Acknowledgment: Recognize that despite timely surgical intervention, in-hospital mortality remains high for patients undergoing emergency procedures for acute subdural hematoma (Evidence: Moderate) 1.References
