[Comparative study of somatosensory evoked potentials, whole body computer tomography and myelography in spinal space-occupying lesions].

Somatosensory evoked potentials (SEP) of the tibial nerve are of diagnostic value, if the recording points nearest to the spinous process are used. In cases with space-occupying lesions of the spinal cord, conduction block or amplitude reduction is the most common abnormality. In contrast in inflammatory diseases like spinal MS the most common abnormality is marked latency delay.

[Diskography--myelography].

One hundred patients were submitted to a prospective, comparative study of metrizamide myelography and discography. In the 32 patients with cervical myelopathy discography yielded no additional information and was thus abandoned. The 68 patients with radiculopathy disease the following results were obtained: In view of the agreement between clinical and myelographic monosegmental findings, discography was considered unnecessary. However, in seven cases with negative myelograms it was possible to show a disc prolapse by discography. When the myelogram was pathological over several segments discography furnished additional information for the differential diagnosis between osteochondrotic or discogenic space-occupying lesions.

[Unusual course of myelography. Case report].

During performing a lumbar myelography the contrast medium, which was injected correctly, suddenly disappeared. By measuring the blood-iodine concentration a flow of contrasting medium into the venous system was found. This phenomenon may explain an acute allergic reaction.

The value of metrizamide CT cisternography in the diagnosis of CSF fistulae.

Post-traumatic CSF fistulae and those affiliated with tumours on the skull base have so far been investigated by isotope cisternography, fluoresceine tests and polytomography. 12 patients have recently been studied by metrizamide CT cisternography. In acute post-traumatic cases difficulties arise in the differentiation between blood clots and the stream of contrast medium. The method was found to be useful in delayed CSF fistulae and tumour-associated cases.

[Direct percutaneous carotid angiography with the Potts-Cournand cannula system (author's transl)].

The indications for carotid angiography and the complications of this procedure are described. A report is given on the technique used in this department for direct percutaneous carotid angiography. A comparison of the PC cannula system in current use -- available in throw-away package form -- with the Buchtala cannula system shows a reduction in the incidence of intra/extramural contrast agent injections.

Cervical disk syndromes: value of metrizamide myelography and diskography.

This paper reports on the respective diagnostic values of myelography with water-soluble contrast media and diskography in a study of 100 patients examined between 1979 and 1981 and operated on because of cervical disk disease. The results of the study led to a change of the diagnostic procedures formerly applied in radicular syndromes (i.e., diskography, and then perhaps myelography) and in cervical myelopathy (myelography, rarely followed by diskography). Now cervical metrizamide myelography is always performed first. Diskography is only indicated in radicular syndromes to determine the segment causing clinical symptoms when there is a polysegmental space-occupying lesion on the myelogram in combination with a mono- or oligoradicular neurologic symptomatology; or in the case of a normal myelogram with complaints resistant to conservative treatment.
