[Scanography and chemonucleolysis of herniated discs. Value and limitations in 20 cases].

Scanography explorations were conducted before and after chemonucleolysis in 20 patients with sciatica from herniated discs. The scanner can improve the selection of patients for this new type of medical treatment by detecting adverse factors: stenosed discs, excluded hernias, narrow canals, stenosis of the lateral recesses. The diagnostic precision of scanography can be demonstrated by comparison of results with those obtained by discography. Following chemonucleolysis, however, intravenous injection of a contrast medium and a high resolution programme are necessary to obtain specific information from scanography.

[Xenon 133 pulmonary scintigraphy. Its significance in the preoperative evaluation of pulmonary function in adolescents with kyphoscoliosis prior to vertebral arthrodesis].

The pulmonary scintigraphy with xenon 133. On its interest in the pre-operative exploration of the kyphoscoliotic youth's lung function before vertebral arthrodesis. The classical functional lung exploration (spirometry, arterial blood gas) gives only a general aspect of the pulmonary function. On the other hand, the pulmonary scintigraphy with Xe 133 studying perfusion as well as ventilation gives into evidence some troubles concerning the distribution of the regional lung volumes together with a general or local increase of the lung on the scoliotic convex side; the base of the latter, whose volume is more important, is the seat of a physiological dead space. The lung on the scoliotic concave side shows a proportional reduction of perfusion and ventilation. We consider this investigation, harmlessly and easily carried out, as essential to observe the evolution of the young scoliotic patients' lung function.
