| Popis: | Cranial extension of the small saphenous vein is of special interest due to the number of anatomical variations and different blood flow patterns observed, which have been described in investigations including postmortem or surgical dissections, phlebographies, and Doppler studies, indicating an earlier and more complex embryological development in relation to the great saphenous vein. A specific type of cranial extension of the small saphenous vein, where a reverse flow is often observed in the valves, was first characterized by Carlo Giacomini. In these veins, caudal flow is normal, with no evidence of valvular incompetence. This article describes anatomical and blood flow patterns found in the small saphenous vein, thus contributing to avoid that normal blood flow aspects are misinterpreted as valvular incompetence. |
