[Extradural hematoma: comparative radiological study between comatose and non-comatose patients]

Area of Science:

• Neurosurgery
• Neurology
• Radiology

Background:

• Extradural hematomas are a significant cause of traumatic brain injury.
• Neurological status is a critical factor influencing outcomes in patients with extradural hematomas.

Purpose of the Study:

• To analyze the outcomes of extradural hematomas based on preoperative neurological status.
• To evaluate the impact of diagnostic methods and associated lesions on patient prognosis.

Main Methods:

• Retrospective analysis of 129 patients with extradural hematomas.
• Classification of patients into comatose (Group I) and noncomatose groups.
• Comparison of outcomes based on diagnostic modalities (CT, angiography, clinical/radiographic assessment) and presence of associated intracranial lesions.

Main Results:

• Comatose patients (n=78) had poorer outcomes compared to noncomatose patients (n=51).
• Diagnostic methods in comatose patients showed varying mortality and good outcome rates: CT (23.3% mortality, 50% good), angiography (48.3% mortality, 38.7% good), clinical/radiographic (47% mortality, 35.2% good).
• Associated intracranial lesions significantly increased mortality and reduced good outcomes in both groups. Frontal hematomas in comatose patients with severe neurological deficits had a high mortality rate (52.6%).

Conclusions:

• Preoperative neurological state is the most consistent predictor of outcome in extradural hematomas.
• Associated intracranial lesions are a major determinant of poor prognosis.
• Diagnostic strategy and timely intervention are crucial, particularly in comatose patients.
