[Peroperative spinal cord ultrasonography in neurosurgery]. / L'échographie médullaire per-opératoire en neurochirurgie.

Intraoperative spinal sonography is a new method of investigation. We are reporting 14 observations. The results of these explorations permit to describe the normal spinal sonography and a spinal ultrasonic semeiology. We underline the advantage of this technic in the neurospinal surgery particularly to locate the tumors and to facilitate the removal.

[Sarcoma of the right superior pulmonary vein: physiopathological study of the progressive stenosis in a lobar vein (author's transl)]. / Sarcome de la veine pulmonaire supérieure droite. Etude physiopathologique de la sténose progressive d'une veine lobaire.

A part from the interest aroused by the exceptional nature of this case of sarcoma of the right superior pulmonary vein, it enabled definition of the angiographic appearances of the affection of the vein. Physiopathological examinations, including vascular redistribution, development of a systemic collateral circulation, and the reflux of hematosed blood into the pulmonary trunk, were able to establish the diagnosis in vivo.

[Coronary anastomosis. Angiographic study and statistical correlation in 140 patients with angiogenic coronary atheroma]. / Les anastoses coronariennes. Etude angiographique et corrélations statistiques chez 140 patients porteurs d'un athérome coronarien anginogéne

A great number of studies devoted to coronary artery anastomoses on the experimental animal or on post-mortem material, while the in vivo studies are relatively rare. The results of these studies are often contradictory, and many questions are still unresolved concerning the part played by the anastomoses in natural history of coronary artery atheroma. On 140 patients, all suffering from angina due to coronary atheroma, a study of the anastomoses visible on coronary arteriograms was undertaken, together with a statistical analysis of the various correlations between the presence or not of coronary artery anastomoses and the various criteria, anatomical, clinical and electrocardiographic.

Emergency selective aortography for acute lesions of the thoracic aorta.

Emergency selective aortography is necessary for the definitive diagnosis of acute lesions of the thoracic aorta and defines their therapeutic possibilities. Cineradiography is very helpful and is complementary fo the roentgenograms. In this paper the study of dissecting aneurysms, tears of the aortic wall, ruptured aortic aneurysms and traumatic aortic lacerations is described. A new anatomic classification of dissecting aneurysms combined with that of De Bakey et al. is presented.
