[Digital subtraction angiography in intracranial vascular malformations].

Abstract

From a total number of 350 DSA examinations in the cervicocranial region intracranial vascular malformations were detected in 14 patients, i.e. in 4%. In six instances an aneurysm was involved, six times arteriovenous and twice a venous malformation. Using digital subtraction angiography, it is usually possible to diagnose by the intravenous or intraaortal route major findings, however, in the majority the finding serves only for orientation. For a more detailed diagnosis, in particular of small findings and findings before operation, a selective examination is more suitable.
