Six-year follow-up of endovenous laser ablation for great saphenous vein incompetence.

Six years after endovenous laser ablation, most patients were improved on clinical grounds, and more than two-thirds had no saphenous insufficiency at echo-color-Doppler. Only a minority had both clinical and echo-color-Doppler-confirmed failures. Anatomical features of the junction and the saphenous diameter both at the junction and at the trunk independently predicted echo-color-Doppler-confirmed failures.
