[Intracranial hematoma as a complication after surgical treatment of meningiomas].

The causes of postoperative haematomas after operations for intracranial meningiomas are analysed. The percentage of this complication in this material was 5.2%. The most frequent concomitant disease in this series was arterial hypertension. The majority of postoperative haematomas was observed after longer lasting operations with totally excised large tumour. Perhaps, one of a large number of causes, is slight coagulopathy.
