The presence or absence of sequelae of a dural hematoma is related to the location of the hematoma, the size of the hematoma, and whether or not it was treated aggressively.
A small amount of dural hematoma usually does not leave obvious sequelae.
If the bleeding is relatively large, some patients may experience headache, dizziness and other minor discomforts. If a huge dural hematoma forms after the injury and the patient is already comatose or even brain herniated, hemiparesis, aphasia, loss of vision, or even prolonged coma and vegetative survival may still occur even after surgery.
A subdural hematoma is an accumulation of blood from an intracranial hemorrhage in the subdural cavity. The subdural space is the cavity between two of the three outer layers of the meninges. After a hemorrhage, blood enters the subdural cavity to form a blood clot called a hematoma. As the hematoma grows in size and compresses the surrounding brain tissue, it can cause a range of symptoms.
Patients with clinically stable acute subdural hematomas with small hematomas can be treated non-surgically. Acute subdural hematomas with large amounts of bleeding: can be treated with different techniques, including drilling and drainage, craniotomy for hematoma removal and debridement and decompression.
If dural hematoma disease is diagnosed, early and standardized treatment is recommended to reduce the adverse effects of the disease.
