Study was performed on 83 great and 64 small saphenous veins obtained from human adults males and females, aged 26 to 85 years. The number of valves in the great saphenous veins varies from 3 to l3, and in the small saphenous veins the number of valves varies from 1 to 8. The mean number of valves in the femoral part of the great saphenous veins is 5 and in the crural part of this vein is 3. The number of valves is not related to the length of vein.
Our studies were carried out on 8 male and 2 female baboons Papio anubis cadavers. We examined a total of 20 hind legs. The vessels of the hind leg were filled with coloured latex. Afterwards we prepared the superficial and deep veins and accompanying arteries. We paid attention to the location, diameter and the course of the long and short saphenous veins. We found many differences between the system of superficial veins in the baboon hind leg and that in the human lower limb. First of all, the long saphenous vein in the baboon Papio anubis presented as two similar trunks that ran together with a concomitant artery. The saphenofemoral junction was also duplicated. The distance between these outlets was about 4 mm and their location was different from that in humans. Neither trunk exceeded 2.5 m in diameter. Some human-like features were noticed in the system of the short saphenous vein in Papio anubis. The diameter of the short saphenous vein and its course and the location of the saphenopopliteal junction were very similar to those in humans. On the other hand, the short saphenous vein was the main superficial venous channel of the hind limb of Papio anubis.
Although the baboon is considered a good animal model in biomedical research, no description of the superficial veins of the foot in Papio anubis is found in the available literature. The current study was conducted to document the anatomy of these veins in the baboon foot. A macroscopic anatomical investigation was carried out on 20 hind legs (10 cadavers) of the adult Papio anubis (9 males and 1 female). The circulatory system of the entire body was filled with coloured latex. Traditional methods were used for the preparation of the veins of the legs. These were then compared with the venous system of the lower extremities in humans as presented in the literature. The medial and lateral metatarsal veins, the dorsal venous network, the long saphenous vein and the short saphenous vein in Papio anubis were described according to their origin, course, opening, length and diameter. The network observed was divided into three types with respect to the connections between the superficial veins. The investigation revealed no symmetry in the venous system of the baboon foot. The short saphenous vein appeared to be the main vein of the hind leg in Papio anubis and the long saphenous vein ran as a double vessel.
