A systolic cervical bruit was heard in both cases. One @entity1 had an incomplete mid-cervical @entity10302 . The @entity292 involved the second portion of the vertebral artery: 1 @entity292 was fed, in addition to the vertebral artery, by the deep cervical artery. Venous drainage was through intraspinal plexus, @entity1150 . One @entity1 was treated with a direct surgical trapping of the vertebral artery proximal and distal to the @entity292 : the other @entity1 , in addition to direct surgical vertebral artery trapping, received an @entity432 . After treatment the @entity292 disappeared, both clinically and angiographically.
