Abstract
We evaluated neurosurgical cases at our hospital from 1959 through 1962 and examined post-operative death cases.
1) They were 19 cases of intracranial tumors 215 cases of head injuries and 7 cases of others.
2) Mortality rate after surgery of intracranial tumors was 29%; 10% in supratentorial and 75% in infratentorial tumors.
3) A case of pinealoma was treated by radiotherapy, which was so effective that the symptome had completely disappeared for a short time, but later on the patient died.
4) In cases of metastatic tumor from carcinoma of the lung, as it tends to occur inn many places, we should remove main tumor and at the same time use other treatment such as chemotherapeutic agent for cancer.
5) In two cases of acoustic neurinomas we attempted to remove completely, but both of them died, so we felt keenly importance of choice of technique.
6) In cases of head injury we operated 15 cases and 3 cases died. That mortality rate was 20%, but all of them were complicated cases in acute distress and had had severe damage in the brain already.
7) On operating cases such as serious head injury, we should proceed as soon as possible and apply hypothermia before operation, through and after.
8) We operated 5 cases of the other intracranial lesion and one died. That mortality rate was 20%.
