Normal venous drainage of the vestibular organs through the vein of the paravestibular canaliculus (PVC) may be crucial to inner ear fluid mechanics. It is proposed that increased venous pressure, with resultant venous insufficiency of the vestibular organs, may result in endolymphatic hydrops unless collateral venous circulation develops. Certain variations in pattern of venous drainage where the vestibular organs drain predominantly through the PVC vein may be a predisposing factor. In patients with Meniere's disease, different mechanisms can cause venous insufficiency. One suggested mechanism is morphologic change in the microcirculation of the intermediate portion of the endolymphatic sac. Microcirculation changes may be associated with fibrosis of the perisac tissues or shortening of the intermediate sac region or might be physiologically determined. Venous insufficiency may also result from anomalies of the PVC vein.
前庭器官通过前庭旁小管静脉（PVC）进行正常的静脉引流，这可能对内耳的流体力学至关重要。有人提出，静脉压升高以及由此导致的前庭器官静脉功能不全，可能会导致内淋巴积水，除非形成侧支静脉循环。前庭器官主要通过PVC静脉引流的静脉引流模式的某些变化可能是一个诱发因素。在梅尼埃病患者中，不同的机制可导致静脉功能不全。一种推测的机制是内淋巴囊中间部分微循环的形态变化。微循环变化可能与囊周组织的纤维化或中间囊区域的缩短有关，或者可能由生理因素决定。静脉功能不全也可能由PVC静脉异常引起。
