Two or three more tributaries join in the midthigh region, in very variable locations. In the lower thigh, an anterior and posterior tributary may be seen joining the great saphenous vein. These appear dilated and tortuous in venous reflux pathology. In the middle third, a vein may join from the lateral side linking the great saphenous vein with the anterior accessory saphenous Fig. 18 Arch veins with a view of the inner side of the right calf. The course of the great saphenous vein is marked green.

The connections between these smaller tributaries are very variable in location. Consequently, they do not have anatomical names. In health, they are invisible to the naked eye, but on ultrasound, they can be demonstrated using a high-resolution probe. They can only be seen through the skin when they are pathologically filled. The anatomy-based consensus document has divided them into tributaries (over 3 mm diameter) and reticular veins (less than 3 mm diameter) (Caggiati et al. 2002). Reticular veins have a profile and are palpable, whereas thread veins or telangiectasia are only visible.
