[CT-guided punctures in the area of the spine. The "fluorotechnique" as localization method].

The increased anatomical resolution of the Computed Tomography allows the localized excision of tissue malformation even less than 5 mm in diameter. Within difficult areas of the body, e.g. the spine, it is possible to reach intra- as well as extraosseous lesions with high accuracy. Results and technique of puncture are reported in 31 patients with unclear diagnosis or therapy (Neurolysis). In 24 cases diagnosis was established or therapy was successful, in 2 cases the result was false negative. In 5 cases the tissue was non diagnostic. According to the low number of complications (n = 1) a repeated study would have been possible.
