BACKGROUND: The aim of the work was the study of neurovisualizing correlates of constitutional venous insufficiency (CVI) in patients with hypertonic dyscirculatory encephalopathy (HDE) using magnetic resonance imaging (MRI).
METHODS: We examined 132 patients with HDE. The patients were divided into groups depending on the stage of the disease and depending on the presence or absence of CVI. All patients underwent 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 control group. In CVI patients, the asymmetry of the transverse and sigmoid sinuses was diagnosed significantly rarer compared to the control group and patients without CVI, regardless of the stage of HDE. The superficial cerebral veins in patients with CVI were significantly wider than in control group and in patients without CVI at all HDE stages. In the CVI group with HDE III patients, we found the increase in size of the sinus rectus compared with control group and HDE III patients. Chronic transverse and sigmoid sinus thrombosis were seen only in groups with CVI in HDE III and CVI in HDE II: 13 thrombosis of the right transverse sinus (56.5%) and 10 left transverse sinus thrombosis (43.5%). Acute thrombosis of intracranial sinuses was not detected.
CONCLUSIONS: The neurovisualization correlates of CVI are the widening of the superficial veins and the veins of Galen, hypoplasia and thrombosis of venous sinuses in the chronic stage.
