Timing of Surgery for the hypertensive intracerebral hematoma should be considered as soon as possible after onset. Especially in severe cases in which the conscious level is stupor, semicoma, and coma, an emergency operation should be undertaken.
However, in mild cases in which the conscious level is alert or somnolent and survival is expected, surgical treatment is indicated for functional recovery. We have analized the surgical results in 33 mild cases of the lateral type of intracerebral hematoma. Surgery was undertaken 8-21 days after onset in 51%, and 22 days-5 months later in 24%. The functional recovery of extremities was satisfactory and considered to be effective in spite of the delayed operation.
Intracerebral hematoma of the subacute or chronic stage appeared to be almost liquefied. Aspiration of the liquefied hematoma was tried by needle insertion into the hematoma cavity, and good recovery from hemiparesis was obtained.
