  • Abstract
  • Look Inside

Conflicting opinions exist concerning the surgical treatment of hypertensive intracerebral hemorrhage. Yet many reports have emphasized the poor out-look offered by conservative management.

With the hope that surgical treatment might be an effective measure in such fatal cases, we have been trying to find reliable operative criteria.

Our study is begin to know the prognosis of hypertensive intracerebral hemorrhage treated con-servatively and to assess the prognostic factors derived from careful observation of 212 consecutive cases. All these cases were diagnosed by clinical symptoms, lumbar puncture, cerebral angiography and/or autopsy.

1. The overall mortality was 44% and 27% of them died within 24 hours and 70% was within 7 days after onset.

2. Mortality rate progressively increase with deepening level of consciousness. Death rate of deep comatose and semicomatose patients is 94% and 64% respectively. On the contrary all the patients who were alert at admission survived.

3. The conscious level is, however, decided upon at a fixed moment in time of admission, so it de-mands consideratiod in evaluation of intervals be-tween onset and admission.

When our partients are regrouped according to their conscious state at the 2 days of admission, death rate of the patients who are semicoma and deep coma within 2 days after onset increase up to 83%.

The urgent operation may offer a chance of recovery in these patients if the initial attack is not overwhelming.

4. Early appearance of papilledema within 48 hours have considerable significance for the pro-gnosis, the mortarity rate being 72%.

We can, therefore, estimate the speed of the hematoma spread by close observation of the pro-gression of conscious level and appearance of papilledema.

5. It is important that the site, size and growing speed of the hematoma be determined preoperatively for the successful surgery. Moreover the emergency surgery must be performed before secondary brain stem compression occurs.
