RESUMEN
Seven patients who had spinal interspace infections underwent clinical, laboratory, and radiographic examinations, and findings are reported. Lytic fragmentation of adjacent vertebral bodies is a characteristic appearance on CT scans. Sagittal-coronal reformations confirm the end-plate irregularity and establish the diagnosis. Since the changes of diskitis are delayed and often obscured by accompanying degenerative disease on plain radiographs, CT appears to offer a diagnostic modality that shortens the usual delay from onset of symptoms to diagnosis.

In the neuroradiologic evaluation of 118 patients using intraarterial digital subtraction angiography definite advantages and disadvantages were defined. Advantages include reduction of contrast medium volume, catheter time, and patient risk and discomfort. It also aids in angiographic planning. The paramount disadvantage is less spatial resolution compared with conventional film angiography.

Sixty-five sites of arterial gastrointestinal hemorrhage in 63 patients were managed with transcatheter therapy. Arterial vasopressin infusion was attempted primarily for all but three sites; embolization was used in these cases and in those for whom vasopressin infusion failed to control bleeding. The results obtained suggest that this regimen, that is, primary vasopressin infusion with embolization reserved for infusion failures or contraindications, is more effective for control of arterial gastrointestinal hemorrhage than the use of either method alone. The role of primary embolization for control of this type of bleeding may need reassessment.

The authors' experience using the Debrun detachable balloon catheter system in occluding surgically-created carotid-jugular fistulas is described. Useful technical points in preparing and using the system are outlined. Technical failures were encountered both in creation of the fistula model and in use of the system, and their occurrence is documented. It is concluded that, when familiarization with the system's operation is attained, the detachable balloon catheter system promises to offer a valuable method of treatment of traumatic carotid-cavernous fistulas in humans.
