Summary:
The authors examined cranial arteries with digital subtraction angiography (DSA) and three-dimensional
DSA (3D DSA) in 52 patients in 2002. They detected 39 intracranial aneurysms. In 30 aneurysms,
3D DSA provided more detailed information than DSA about the anatomical relationships of the
aneurysms, which was in 7 aneurysms decisive for the selection of the therapeutic approach. Three-dimensional
images were very useful specifically for planning endovascular aneurysmtreatment but also
for the selection of optimal surgical approach, especially in the presence of more complicated anatomical
relationships. 3D DSA extends the diagnostic possibilities by providing spatial imaging of
aneurysms.
Key words:
