Management of Dual Intracranial Hematomas

Surgical Prioritization

When managing patients with coexisting subdural and epidural hematomas, prioritize evacuating the epidural hematoma first, as it is more likely to expand rapidly and cause acute herniation, regardless of which appears thinner on initial imaging, according to the American Society of Anesthesiologists 1, 2
The epidural hematoma shows mass effect, even if thinner than a coexisting subdural hematoma, epidurals are anatomically confined by suture lines, creating concentrated pressure in limited space that accelerates neurological deterioration, as stated by the American College of Surgeons 3
Subdural hematomas with thickness >5mm and midline shift >5mm require surgical evacuation, as recommended by the Brain Injury Foundation 2
The epidural is truly minimal (<5mm) without mass effect and the subdural is causing significant intracranial hypertension, according to the American Association of Neurological Surgeons 1, 2

Small hematomas of either type can expand rapidly in elderly or anticoagulated patients, as noted by the American Geriatrics Society 4

After evacuating the priority hematoma, ICP monitoring is mandatory to detect expansion of the remaining lesion or development of new hemorrhage, as recommended by the Neurocritical Care Society 1, 2
Maintain CPP between 60-70 mmHg and avoid hypocapnia, which induces cerebral vasoconstriction, according to the American Heart Association 1, 2
Combined surgical strategies may be necessary, such as acute coiling of a ruptured aneurysm with simultaneous surgical decompression of associated hematoma, as stated by the American Stroke Association 5
