The Influence of Laser Crossectomy With Different Wavelengths on Varicose Vein Progression
Sponsor: Pirogov Russian National Research Medical University
Summary
Technically successful laser crossectomy will reduce the risk of reflux recurrence at the sapheno-femoral junction without increasing the risk of endovenous heat-induced thrombosis, which may positively impact the likelihood of ultrasound- or clinical-recurrence of varicose veins. Similar technical efficacy is expected for laser crossectomy at 1940 nm and 1470 nm. A possible advantage of the 1940 nm wavelength in terms of postoperative pain intensity and the risk of adverse events cannot be ruled out.

Interventions
Laser crossectomy on 1470 nm
Attempt to perform laser crossectomy with radial fiber (core of 0.4 mm, bulb of 1.57 mm) on the 1470 nm wavelength laser with a power of 6-8 W and an LED of 60-80 J/cm. Performing the GSV trunk ablation according to the indications.
Laser crossectomy on 1940 nm
Attempt to perform laser crossectomy with radial fiber (core of 0.55 mm, bulb of 1.4 mm) on the 1940 nm wavelength laser with a power of 4-6 W and an LED of 40-60 J/cm. Performing the GSV trunk ablation according to the indications.
Standard EVLT with a stump
Attempted laser crossectomy on 1470 nm or 1940 nm failed due to anatomical features of the SFJ or technical reasons, and the GSV trunk was obliterated with persistence of the stump.
