Clinical and Duplex-Sonographic Outcomes of 1,320-nm Endovenous Laser Treatment for Saphenous Vein Incompetence

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.
