[Angiographic findings in cerebral aneurysms (author's transl)].

The angiograms of 140 patients with congenital intracerebral aneurysms were examined, and specific angiographic findings correlated to course and prognosis of the patient. Vascular spasm at or near the aneurysm seen shortly after its rupture seems to be a protective measure against further hemorrhage. Persistance of spasm for over a week, however, is a bad prognostic sign. Decreased blood flow in the aneurysmal cavity itself on initial angiography was frequently accompanied by an increase in recurrent hermorrhage. This was also true for aneurymsm with multiple lobulations. A mass effect with midline shift was seen in 20% of the patients.
