Chronic cerebrospinal venous insufficiency in patients with Ménière’s disease

To analyze the presence of chronic cerebrospinal venous insufficiency parameter and vascular abnormalities, in the internal jugular veins (IJVs) and/or vertebral veins in sitting and supine posture, in patients with Meniere’s disease compared to healthy general population. A prospective study on 32 patients affected by definite Ménière was performed from February 2012 to January 2013. All subjects underwent an echo-color Doppler examination of the cerebrospinal venous flow. 21 of the 32 Menieric patients showed a statistically significant reflux in the intracranial veins versus healthy (65.6 vs 25%; P < 0.001). A high prevalence of IJVs stenosis with hemodynamic changes (increased velocity or absence of flow) was observed (66.7 vs 33.3%; P < 0.05). The other parameters considered did not show statistically significant differences among the two groups. The results obtained showed a vascular pattern of cerebrospinal venous system present in patients affected by definite Meniere. This vascular impairment significantly affects the vascular areas more directly involved in the venous drainage of the inner ear. Thus venous stasis may be considered a further pathogenetic mechanism for development of Meniere’s disease.
