Anevrysmal dilatation can occur in the short saphenous vein at the saphenopopliteal junction (Figure 103).This dilatation can make a ligation flush with the popliteal vein particularly difficult.
In this case, recurrence is related to an anatomical factor accentuating the hemodynamic factor. Varicose veins will then develop not on a perforating vein of the popliteal fossa independent of the short saphenous vein, but on the stump of the ectatic saphenopopliteal junction. For example, figure 104 illustrates an early recurrence, occurring 5 months after saphenopopliteal junction ligation and short saphenous vein stripping.
