Magnetic resonance imaging in constitutional venous insufficiency diagnostics in patients with hypertensive discirculatory encephalopathy

The objective of the study is to examine the neuroimaging correlates of constitutional venous insufficiency (CVI) in patients with hypertonic discirculatory encephalopathy (HDE). Material and Methods. 132 patients with HDE were examined. The patients were divided into groups depending on the disease state and the presence or absence of Coverall patients underwent magnetic resonance imaging (MRI) and MR-venography. Results. Hypoplasia of the transverse and sigmoid sinuses was significantly higher in CVI group compared with the NP at all HDE stages and the CG. In CVI the asymmetry of the transverse and sigmoid sinuses was diagnosed significantly rarer compared to the CG and NP, regardless of the HDE stage. The superficial cerebral veins in patients with CVI were significantly wider than in CG and in NP at all HDE stages. In the CVI group with HDE III we found the increase in sinus rectus size compared with CG and the HDE III. Chronic transverse and sigmoid sinus thrombosis were seen only in groups with CVI in HDE III and CVI in HDE II: 2 cavernous sinus thrombosis (33.3 %), 4 thrombosis of the right transverse sinus (50 %) and one left transverse sinus thrombosis (16.7 %). Acute thrombosis of intracranial sinuses was not detected. Conclusion. In patients with HDE and clinical manifestations of the CVI the structure of transverse and sigmoid sinuses (asymmetry and hypoplasia) and MR-signs of intracranial venous congestion in the superficial cerebral veins, increasing the size of the vein of Galen as well as chronic thrombosis of the sinuses are significantly more visualized.
