[The angiographic diagnosis of vascular spasm in ruptured cerebral aneurysms].

The authors compared the results of qualitative and quantitative appraisal of arterial spasm according to the angiographic findings in 85 patients with the severity of their condition and neurological symptomatology in the acute period of rupture of a brain aneurysm. The spasm was diagnosed by quantitative appraisal in 80% and by qualitative appraisal in 72.9% of cases. Appraisal of the spasm in various periods after rupture of the aneurysm showed it to be most intense on the 9th-10th day. The vascular spasm (VS) was the main cause of the neurological symptomatology in the acute period of rupture of the aneurysm. Constriction of the arteries to 1.65 in quantitative appraisal of the spasm and its extension to 3-4 segments and more in qualitative appraisal were attended by diffused consciousness and stem and focal hemispheric symptomatology. Simultaneous use of both methods for VS appraisal makes it possible to evaluate its extension and the degree of arterial constriction and distinguish the most severe forms of spasm.
