To study the clinical and MRI features of cerebral venous blood flow disorders in patients with arterial hypertension and chronic brain ischemia.
Material and methods
We studied 132 patients with chronic brain ischemia who were distributed into groups depending on the severity of ischemia and the presence of constitutive venous insufficiency. All patients underwent neurological examinations, brain MRI and MR-venography.
In patients with constitutive venous insufficiency, the hypoplasia of transverse and sigmoid sinuses (57.5%), dilatation of superficial brain veins (68.5%) and vein of Galen (65.6%), chronic thrombosis of vein sinuses (24.7%) were more prevalent than in patients without venous blood flow disorders and were associated with clinical signs and symptoms of cerebral venous dyscirculation.
Brain imaging with neurological examination allows to identify cerebral venous blood flow disorders and to optimize treatment in patients with chronic brain ischemia.
Constitutive venous insufficiency, chronic brain ischemia, MRI, cerebral venous sinuses thrombosis, hypoplasian of venous sinus, vein of Galen.
