BACKGROUND: Endovenous laser treatment (EVLT) can be performed using different wavelengths with different absorption rates and characteristics, but limited data are available regarding wavelength-related side effects and efficacy. OBJECTIVE: To evaluate the safety and efficacy of 1,320-nm EVLT for treating saphenous vein incompetence. METHODS AND MATERIALS: A 1-year retrospective study was performed using clinical and Duplex-sonographic follow-up data from patients treated using an 810-nm or 1,320-nm laser. RESULTS: The difference in clinical improvement after EVLT between the two groups was statistically significant. Improvement in venous clinical severity score (VCSS) was greater in the 1,320-nm group than in the 810-nm group, but improvement in Aberdeen Varicose Vein Severity Score was not statistically significantly different between the two groups. Ultrasonography-proven recanalization rates 1 year after surgery were 11.1% for the 810-nm group and 6.5% for the 1,320 nm group (p < .05). CONCLUSION: EVLT using a 1,320-nm laser had better clinical outcomes and lower recurrence and recanalization rates than EVLT with an 810-nm laser.
