  • Abstract
  • Look Inside

We have reported the results in 120 case with intrcranial aneurysm (s), managed conservatively and pointed up the priniciple regarding the treatment for aneurysm.

1. Over all mortarity rate was 74%, and 65% of them died within one week after initial bleeding.

2. Of 32 cases of deaths due to first bleeding, 27 cases (84 per cent) died within 72 hours of hemorrhage. These patient's condition at 12-24 hours after onset were in Grade 5 by Botterell's classification.

3. Of 51 cases of deaths due to rebleedingepisodes, only 2 cases (4 per cent) died within 72 hours and 45 cases (88 per cent) died after one week.

4. The many of these cases were in good condi-tion at the time of onset, 27 cases (53 per cent) being in Grade 1 or Grade 2.

5. The risk of rebleeding rises rapidly to a peak by the end of first week and each rebleeding episode had a tendency to increased mortality rate.

6. Incidence of rebleeding was higher when an-eurysm was located at the more proximal portion and had locurarity. On the contrary the incidence of rebleeding was lower when sclerosis was remark-able on angiogram.

7. In conclusion, if the patient is in good con-dition of Grade I or II, surgery should be done with out delay, when ever possible, before 7 days have elapsed. For the poor risk patients of Grade III-V, they should be divided into two groups, as follow, A group : emargency surgery should be done at once, and B group : surgery should be delayed until] 7th day after onset.
