Abstract
The outcome of a series of 73 patients with spontaneous intraparenchymatous haematomas treated by surgical evacuation of the clot and decompressive craniectomy has been described. Comparing postoperative mortality of this series with another series of patients (54 cases) treated only with surgical removal of the clot without decompressive craniectomy a statistically significant improvement in the mortality rate after craniectomy could be observed in acute cases demanding surgical intervention for preservation of life in the first 24 hours. If signs of brain-stem suffering appear surgical mortality increases proportionally to the duration of this symptomatology. In these cases surgery, if it is to be useful, has to be performed as soon as possible. The morbidity of the surviving patients is not greater in this series with decompressive craniectomy than in series without decompression.
