[Traumatic lesions of the brachial plexus. Evaluation of 144 cases studied using direct cervical myelography and non-ionic contrast media].
The authors report their experience in 144 patients with traumatic brachial plexus injury who underwent Direct Cervical Myelography (DCM). Sometimes the diagnostic investigation was completed by CT. Various myelographic patterns are described: pseudomeningocele, missing sheet of the root, scarring lesions. In 9 cases only, myelography was not sufficient to provide a complete diagnosis. The examination showed all plexus roots lacerated in 14 patients, a monoradicular lesion in 75 cases, and no lesion in 26 cases. Twenty-one out of the 26 negative cases were confirmed during surgery, while in 2 patients an intraspinal injury was found, which had not been detected due to the presence of scars. Scars often compress healthy roots, and may mask intraspinal injuries. In such cases, and when the spinal cord stretches towards the side of the lesion, Myelo-CT can be useful. DCM proved to be an extremely sensitive and specific method, which can be used as a first-choice radiological procedure in the study of traumatic injuries of the brachial plexus.
