Subdural Hematoma – What, Causes and Treatments We Should Know. In addition, Subdural Hematoma is a blood condition resulting from bleeding in the meningeal sites between the dura and arachnoid .
To better understand what happens, it should be remembered that there is a virtual “gap” between the arachnoid membranes, which surrounds the brain , and the dura mater, which lines the skull internally. Between the two there is a thin vascular network that can break in case of trauma or accidents or trauma, generating a bruise.
Because the skull is a rigid, closed box, subdural bruising greatly increases the pressure inside the skull, leading to severe symptoms and sometimes even death.
The mortality caused by them is very high and they are among the leading causes of death from brain disease.
