[Spontaneous intraparenchymatous hematomas. Experience with 134 cases]. / Hematomas intraparenquimatosos espontâneos. Experiência com 134 casos.

One hundred thirty four cases of spontaneous intraparenchymatous hematomas have been studied. They were separated into six groups according to criteria related to topography, level of consciousness, and hematoma volume. Treatment protocols--conservative, conservative with I.C.P. monitoring, and surgical--were different in each group. Results have shown an increased mortality (p < 0.05) among patients whose level of consciousness were more severely compromised, in those older than 50 years old, and in those harbouring quadrilateral, intraventricular or brainstem hematomas. Overall mortality was 26.1%.
