Immediate refilling of the varicosity despite manual occlusion indicates that the principal entry point has not yet been identified or that more than 1 reflux pathway is involved. Extremely rapid refilling despite occlusion of the superficial reflux pathways suggests that the valves in the deep veins may be incompetent between the groin and the level at which the reflux escapes the deep system. The result is rapid filling of the superficial system.

If deep venous insufficiency is confirmed with results from further evaluations, the treatment options for the patient may be severely limited.
