[On the intracerebral hematoma --clinical analysis of 105 operated cases-- (author's transl)].
The hematomas occupied between the inner surface of skull and brain surface are well known and the majority of these intracranial hematomas are elicited by head injury. On the other hand, the intracerebral hematomas formed in the brain tissue are produced by the various causative diseases and the majority of these cause are cerebrovascular disease. The causative diseases of intracerebral hematomas were cerebrovascular diseases like hypertension, intracranial aneurysm and cerebral arteriovenous malformation in 65.7% and head injury in 32.4%. ⋯ Consciousness change in patients of spontane intracerebral hematoma were only 50.0%. Motor disturbance as clinical symptom were 85.0% in hypertensive intracerebral hematoma and this frequency was highest in all causative diseases. The frequency of coincidence between the side of dilated pupil under anisocoria and the side of hematoma was less than 50.0% in average and this frequency was marked lower by compared with the frequency in patients of hematome formed between the skull and brain surface.
