Digital subtraction angiography in intracranial vascular malformations

Out of 350 DSA examinations of the cervicocranial region, intracranial vascular malformations were detected in 14 patients, i.e., in 4%. In six cases aneurysms were observed, six times arteriovenous and twice venous malformations were found. Digital subtraction angiography can usually be employed to diagnose major lesions via the intravenous or intraaortal route, the finding, however, is largely informative only. For a more detailed diagnosis, in particular of small lesions and in pre-operative examinations, selective examination is more suitable. (author). 7 figs., 6 refs
