[Prognostic importance of the study of venous drainage in cerebral arteriovenous aneurysms].
The authors analysed in particular the venous drainage of 370 arteriovenous aneurysms operated during 20 years in neurosurgery at Lille's Hospital. If in many cases the study in details of the different arterious pedicles take an important place in the discussion of the indications and operative technics; in other cases a bad estimate of the interest of careful study of veins can be at the beginning of great disappointments. Also the authors insist on the necessary study of the venous system in totality by seeing after agenesia of some passages, the respective drainage of the angioma and the brain, the existence of a saturation venous phenomenon. The analysis in details of the anatomical and functional distribution of the venous drainage in these malformations can be taken into consideration in the operative decision. The analysis of results in ten preference observations suggest that it is an important element in the arteriovenous aneurisms' evolution and in the final prognostic.
