[Structural and functional anatomical bases of deep venous insufficiency of the lower limbs]. / Bases anatomiques structurales et fonctionnelles de l'insuffisance des troncs veineux profonds des membres inférieurs.

The authors consider the Extent of the several anatomical structures which constitute the deep venous network, and the part they can take in the case of deep venous insufficiency. Congenital Vascular diseases are called back in mind when considering Embryology, and point out the extent of the deep venous state; such veins can gather in periarterial plexus, at the muscular Level, and in going past all along main arterial axes. Among all the critical points of these axes, we must keep the popliteal veins, the femoral crossing, and the iliocaval one and elsewhere, the important question of venous valves and communicating and perforating veins. The part of the lymphatic network must be pointed out, because of its extent in the stasis phenomenons.

[Spontaneous dissection of the internal carotid artery]. / Dissection spontanée de l'artère carotide interne.

Spontaneous dissections of internal carotid artery are known from more than 30 years and their incidence is now specified, several hundred cases being published. The case reported here illustrates very well the setting problems of this disease and explains why the incidence of the mild forms has been underestimated. The case of a sixty years old man with vague vertiginous feeling, headache and moderate ocular troubles is presented. The clinical signs disappeared within six weeks. The patient was seen again in good health seven years later. The medical practitioner by asking a systematic Doppler examination led to the diagnosis confirmed by arteriography. A complete recanalization of the internal carotid artery occurred. These forms with spontaneous favourable prognosis represent at least 50% of the cases.
