[Usefulness of epidurography in the diagnosis of pathological changes in the vertebral canal].

The authors evaluated 60 epidurographies performed in patients with suspected compressing lesions in the vertebral canal. It was demonstrated that epidurography may be a useful method for diagnosis of pathological conditions in the vertebral canal, particularly in its thoracolumbar part. In many cases this method is sufficient for establishing full diagnosis, not infrequently it should be applied as a supplementary procedure (e.g. for evaluating the structure of the vertebral canal or for accurate assessment of the size of the tumour situated in the canal) and in cases with high-grade stenosis of the canal it is the method of choice. Moreover, it was found that epidurography is a method of low invasiveness, not harmful and well tolerated by the patients.
