The presurgical clinical diagnosis of vascular micromalformations and cavernous defects of the brain vessels is one of the most intricate problems. Forty-seven observations of patients with verified histological diagnosis of various vascular micromalformations: arteriovenous, venous, cavernous, and undifferentiated ones were analyzed. There was a direct relationship between the clinical course of defects and difficulties in presurgical diagnosis, on the one hand, and the type of vascular micromalformations, the presence of hematomas, residual recurrent hemorrhages, vascular thromboses, the degree of glial hyperplasia and a tumor, on the other. The analysis of 50 observations of patients with cavernous malformations of different sizes demonstrated the heterogeneity of a histological pattern in this type of vascular pathology and the relationship of the clinical course to the morphological structure of cavernous malformations. This is indicative of the necessity of making a comprehensive examination of patients with cavernous malformations.
