[Results of radiculomyelography with dimer-X following lumbar intervertebral disk operations].

In radiculomyelogram after operation of lumbar intervertebral disk has been investigated an adhesive arachnopathy in 24 out of 86 patients. It appears increased in patients with two operations of the intervertebral disk, revision of several intervertebral spaces and after massed prolapses. The etiological importance of hyperosmolar X-ray contrast media is comparatively slight. Characteristical clinical findings were not evident in patients with arachnopathy. In some patients the protein content in cerebrospinal fluid was raised, it could be observed as an unspecific reaction and a relative monocytosis in the cytogram. Two third of the patients with recurrent nucleus pulposus prolapse were diagnosed rightly by radiculomyelography, though there are difficulties in the differentiation of adhesive-fibrotic changes.
