[Spontaneous intracerebral hematomas in the material of the Department of Neurosurgery of Medical Academy in Lublin].

Between 1972 and 1991, 170 patients with spontaneous nontraumatic intracerebral haematomas were treated in the Neurosurgical Department of Medical Academy in Lublin. In 89 (52.5%) patients, the haematomas were caused by ruptured aneurysms; in 14 (8%), by angiomas; 67 (39.5%) haematomas had other etiology. Within the latter group of patients, 27% suffered from hypertension. Hypertension was also found in 15% of the patients with aneurysms and in 7% of the ones with angiomas. 34% of the haematomas were localized in the temporal lobe, 28%-in the frontal lobe, 3%-in parital lobe, 2%-in occipital lobe, 23% of haematomas were multi-lobal, 8% were found in deep brain structures, and in 2% haematomas were found in cerebellum. 128 patients underwent operative treatment, with a mortality rate of 26%, while 42 patients were treated conservatively, with a mortality rate of 19%. Basing on this material, the authors discuss indications for operative treatment of the haematomas.
