Remaining varicose veins ("Restvarikosis") after phlebexhairesis should be treated with sclerotic- and compression therapy, while often recurrent varicose veins ("Rezidivvarikosis") are an indication for re-operation. Main faults in phlebexhairesis are incomplete ligations of the tributaries of the saphenous vein. Iatrogenic damage of lymphatic vessels in the region of the foramen ovale should be reduced by very careful preparation of this region.
