[Superior mesenteric artery syndrome after surgical correction of severe dorso-lumbar deformities. Authors' experience]. / La sindrome da compasso aorto-mesenterico dopo correzione chirurgica delle gravi deformità del rachide dorso-lombare. Nostra esperienza.

The authors report two cases of superior mesenteric artery syndrome observed in 22 operations for severe spinal deformities. Medical, dietary and postural treatment enabled the situation to be resolved in one case; whereas an intestinal derotation according to Strong-Valdoni was successfully performed in the other. The various surgical alternatives are discussed.

[Reduction of doses in teleradiography of the spine. Criteria of radiation protection and studies of dosimetry]. / Riduzione della dose nella teleradiografia del rachide. Criteri radioprotezionistici e ricerche dosimetriche.

To reduce the radiation exposure during full spine X-ray examinations, the following techniques were instituted: 72" tube to film distance; X-ray beam collimation; fast screen-film combination (rare earth gradual screens with high speed films); additional compensation filters; shielding of the most radiation-sensitive organs. Dosimetric measurements are reported. A very high reduction in exposure, above all of breasts and gonads, was obtained, without significant loss in the quality of radiographs.

[Modern standards in the radiological study of vertebral scoliosis and kyphosis (author's transl)]. / Moderni criteri nello studio radiologico della scoliosi e della cifosi vertebrali.

We must take note of some useful tests for a correct and complete radiological valutation of vertebral scoliosis and kyphosis. Moreover, we have to consider analytically the relative indications and the diagnostic elements, that each of them might give. Technical inventions and practical criterions have also been taken into consideration since they limit the risks caused by being exposed to ionizing radiations.
