Microscopic observations on the great saphenous vein at the upper third level of the thigh and at the level of discharge into the femoral vein

For the microscopical study of the great saphenous vein wall, the venous segments from six male necropsiedcadavers: were obtained three young individuals between 16 and 35 years old and three aged individuals between 50 and 83 years old. The tunica media of the great saphenous vein at the upper third level of the thigh belonging to both young and aged individuals is made up of two layers: an internal formed by fascicles of smooth longitudinal muscular fibers and the external layer made up by fascicles of smooth circular muscular fibers. At the level of the discharge in the femoral, the tunica media of the great saphenous vein wall of both, young and aged individuals, is made up of one layer, whose fascicles of smooth muscular fibers are circularly orientated in relation to the vascular axis. The tunica adventitia of the great saphenous vein wall at the upper third level of the young individuals thigh, presents elastic fibers whereas it the aged individuals it is made up of fascicles of smooth longitudinal fibers; at the level of the femoral vein disdarge in both young and aged individuals, the tunica adventitia presents a fiber elastic constitution. The young and aged individuals' parietal venous valve is elastic fiber in nature. The young individuals' ostial valve is also elastic and that of aged individuals is muscular fiber in nature.

Anatomical observations on the human great saphenous vein

During the dissections of the lower limbs we observed that the most frequent occurrence of the forms of discharges of the great saphenous vein tributaries was one observed in 29.09 per cent of the cases, where the superficial epigastric vein and superficial circumflex iliac vein make up a veinous trunk discharging in to the great saphenous vein, and the external pudendal and the "lateral accessory saphenous" veins drain separately into the great saphenous vein. In the male right lower limbs, the average distance between the pubic tubercle and the great saphenous vein arch upper border was 3.98cm and 3.9lcm for the left lower limbs. In the male right lower limbs, the diameter average of the great saphenous vein arch was l.O2cm and l.O6cm for the male left lower limbs. At the hiatus saphenus level, the wall of lhe great saphenous vein clings to the sieved fascia and the femoral sheath. We have observed the presence of the parietal venous valve at the lumen of the great saphenous vein upper segment; and also the ostial venous valve near the draining of the great saphenous vein into the femoral vein.
