RESUMEN
In the course of a complex experimental study concerning the effects of highly positive acceleration on gestation and development of the neonate, investigations were carried out of ultrastuctural myocardial lesions in the pregnant rat exposed to prolonged gravitational stress (+ 2G). The experimental animals presented various disseminated and partly irreversible myocardial lesions whose pathogeny is discussed.

Three cases are presented of endo-thoracic goiters with posterior, retro-vascular developement, a very rare variety of the mediastino-cervical goiter. The anatomic pathways are described, along which this variety of goiter can migrate inside the thorax, as well as the radiologic signs which allow to make a diagnosis. In view of making a choice of the access route the importance of the diagnosis is particularly stressed, before surgery is attempted. It is also demonstrated that the best route is the vertical cervicosternotomy of the partial type (the Welti technique), completed by antero-lateral thoracotomy in the III-rd right intercostal space.

The authors present a surgical technique for the treatment of oeso-tracheal fistula located in the left supra-hylar fossa, by mobilization of the aorta and ligature of the first intercostal arteries, which provide sufficient light for the surgical procedures. The technique described is illustrated by a personal observation demonstrating its value by the simplicity of the post-operative evolution and the complete recovery. Stressing the difficulty encountered in the pre- and intraoperative localization of the fistula, the authors consider that the technique proposed by them is the type of the necessity technique, the only one allowing to perform a direct surgical approach of the fistula at this level.
