The vein of the cochlear aqueduct (VCAQ) is the principal drainage vein of the cochlea in the guinea pig. Morphological observations of the VCAQ and its adjacent structures were made by studying serial sections of the cochlea. We detected the presence of two collateral vessels from the mucoperiosteal veins of the middle ear which communicated with the VCAQ. Following acute occlusion of the VCAQ, marked dilatations of these vessels were observed in corrosion cast preparations. Our findings suggest that these vessels act as collateral veins following acute venous congestion of the inner ear.
耳蜗导水管静脉（VCAQ）是豚鼠耳蜗的主要引流静脉。通过研究耳蜗的连续切片对VCAQ及其相邻结构进行了形态学观察。我们检测到中耳粘膜骨膜静脉有两条侧支血管与VCAQ相通。在VCAQ急性闭塞后，在铸型标本中观察到这些血管明显扩张。我们的研究结果表明，这些血管在急性内耳静脉充血时起到侧支静脉的作用。
