Long-term results of patients who underwent outpatient laser treatment for varicose veins at the great saphenous vein (GSV) or small saphenous vein (SSV) in 2008–2009 have been published in the Journal of Vascular Surgery: Venous and Lymphatic Disorders.
The Italian research team led by physician Patrizia Pavei (University Hospital of Padua, Padua, Italy) used a cross-sectional survey to examine patients who were all treated with the same parameters: a 1,470nm diode laser and the radial fibre newly developed by Biolitec in 2008.
Of the patients treated in 2008 and 2009, a total of 203 were re-examined and interviewed in 2018. Of these, 79% had been treated at GSV and 21% at SSV. Ten years after laser therapy, approximately 98% of all those treated were still asymptomatic or showed significant improvement. Subsequent treatments occurred in just 21% of the SSV group and 5% of the GSV group. Recanalisation was noted in only one otherwise symptom-free patient.
According to a Biolitec press release, the study showed overall excellent long-term results for the minimally invasive ELVeS Radial laser therapy with the 1,470nm diode laser. This laser gave rise to the Leonardo laser family, which has been continuously developed ever since. Meanwhile, the Leonardo Dual is available in three different versions with 45, 100, and 200 watts, as well as the Leonardo Mini with 10 watts.
