Case Reports[Another new etiology of vertebral artery insufficiency--a case of dynamic entrapment of the vertebral artery by the cervical nerve].
In the etiology of vertebral artery insufficiency, cervical spondylosis with uncal osteophyte, Power's syndrome, A-V malformation and atheromatous narrowing have been recognized. We recently experienced a patient with episodic vertigo and hyposthenia of the left side of the body on rotational movement of the neck. ⋯ With the release and resection of the injured nerve, the patient became free of any vertigo or hyposthenia. Although this kind of etiology involving entrapment-constriction of the vertebral artery by the cervical nerve after trauma has not been reported at all in the literature, we should always keep this in mind when dealing with patients with cervical vertigo after trauma.
