Is there recanalization of the great saphenous vein 2 years after endovenous laser treatment?

PURPOSE

To report the 2-year single-center results of endovenous laser treatment (EVLT) for reflux in the great saphenous vein (GSV).

METHODS

From January 2002 to January 2003, 85 symptomatic patients (56 women; mean age 49 years, range 27-80) underwent EVLT in 100 limbs. All patients were symptomatic, and the majority (67, 79%) had CEAP clinical class C2 venous disease. After treatment, they were monitored by clinical evaluation and duplex imaging.

RESULTS

The initial treatment was completed in 93 limbs. Complications consisted of bruising (31%), tightness (17%), pain (14%), induration (2%), and superficial thrombophlebitis (2%). No severe complications were observed. Over a mean follow-up of 29 months (range 24-37), 3 patients died and 14 were lost to follow-up, leaving 88 (95%) and 76 (82%) limbs available for imaging surveillance at 1 and 2 years, respectively. At 3 months, treatment was anatomically successful in 84% of cases (78 complete occlusion, 7 partial occlusion, and 8 nonocclusion) and functionally successful in 89% (83 no reflux, 10 reflux). All technical failures and 73% (n=11) of the treatment failures occurred in the first half of the studied population, indicating a learning curve effect (p=0.015). Mean energy delivered per unit length was 39+/-8 J/cm (range 25-65) for successful treatment (n=78) and 30+/-10 J/cm (range 21-50) for failed treatment (n=15). No recanalization or recurrent GSV reflux after anatomically and functionally successful treatment was observed in 73 and 61 limbs at 1 and 2-year follow-up, respectively.

CONCLUSIONS

EVLT is a feasible, safe, and fast procedure for eliminating GSV reflux and has excellent cosmetic results. Despite the learning curve, we believe that the treatment results are promising. When successful treatment is achieved by EVLT, a prospective follow-up of 2 years demonstrates durable results.
