Treatment of a<unk>  depends on its size and rate of growth. Some small<unk> s can be managed by careful monitoring as the blood clot is eventually resorbed naturally. Others can be treated by inserting a small catheter through a hole drilled through the skull and sucking out the hematoma. Large or symptomatic hematomas require a craniotomy. A surgeon opens the skull and then the dura mater; removes the clot with suction or irrigation; and identifies and controls sites of bleeding. The injured vessels must be repaired. Postoperative complications can include increased intracranial pressure, brain edema, new or recurrent bleeding, infection, and seizures. In patients with a chronic<unk>  but no history of seizures, it is unclear whether anticonvulsants are harmful or beneficial.
