The outcome of epidural hematoma (EDH) varies greatly from person to person. Factors that affect outcome include:
In general, if you have a typical EDP, your prognosis is good if the hematoma is discovered quickly and removed and you haven’t slipped into a coma. EDHs caused by a bleeding artery develop rapidly and can be found quickly. EDHs caused by a tear in a vein develop more slowly, which can delay finding and treating them. The larger the size of the hematoma, the lower the odds of a good outcome.
