[Venous angiomas of the brain. Retrospective study of angiograms and clinical material].

The aim of the investigation was to reveal the existence of venous angiomas of the brain by serioangiography in selected neurological diseases and to test the possible connection between the angiographic finding of a VA and neurological symptomatology. The material was formed by 386 serioangiograms in patients with subarachnoid haemorrhage, intracerebral haemorrhage, focal epilepsy and unilateral headache. It was revealed that from the total number of mentioned diagnoses there were 18 venous angiomas, i.e. 4.66%. Intracerebral haemorrhage and unilateral headache were most frequent (7.3% and 9%). No difference was found between the right and left hemisphere and between different brain areas. Cerebral angiography remains an important method in the diagnosis of venous angiomas of the brain, provided a satisfactory programme and high quality material are used. Examination by computed tomography without a contrast is of little diagnostic value, the use of contrast in computer tomography can improve the diagnosis.
