[Radicular artery thrombosis after cervical anterior approach for cervico-brachial neuralgia (author's transl)].

An anterior cervical approach completed by a bone graft is performed on a man suffering from cervico brachial neuralgia which did not improve by medical treatment and rest. During four months, the post operative course is excellent, with complete disappearance of pain and regression of the pre-existing neurological deficit. At the end of this period, the appearance of a major deficit within the field of the concerned root led to a selective brachial angiogram which revealed the existence of a radicular artery thrombosis.
