Laser Saphenous Ablations in More Than 1,000 Limbs With Long-Term Duplex Examination Follow-Up

Endovenous ablation with 940 nm laser for the treatment of the great saphenous vein insufficiency: the short-mid term results

“…Van Rij et al (16) documented DVT in 5.3% of their patients' limbs after varicose vein surgery; however, the majority of these thrombi were localized to the tibial veins. As demonstrated by previous trials and case studies, DVT in patients who have undergone EVLA is rare, with a reported incidence of 0% to 6% (6,17).…”

Comparison of 1470 nm Laser and Radial 2ring Fiber with 980 nm Laser and Bare-Tip Fiber in Endovenous Laser Ablation of Saphenous Varicose Veins: A Multicenter, Prospective, Randomized, Non-Blind Study

“…Vein occlusion was defined as incompressibility with an ultrasound transducer and compressibility with absence of blood flow induced by calf squeezing or presence of blood flow, but the extent was 5 cm or less. [17][18][19] (2) Safety For pain assessment, patients without pain and with tolerable pain requiring no additional analgesics were regarded as having no pain, and those requiring an additional analgesics or topical cooling or those in whom pain affected their activities of daily life were regarded as having pain. The VAS was evaluated using a VAS scale measuring 100 mm in length.…”

“…16) Furthermore, there is a patency with blood flow measuring 3 cm or less at the saphenous junction after endovenous ablation; therefore, most patients with a patency measuring 5 cm or more are regarded as showing unsuccessful results. 18,19) Based on these findings, in this clinical trial, when there was no blood flow despite compressibility, including cases in which the area of blood flow measured 5 cm or less, the efficacy was evaluated, regarding it as occlusion. Twelve weeks after surgery, there was no patient with compressibility or blood flow at sites other than the saphenous junction in either group.…”

Laser saphenous ablation results with at least one year of follow-up

“…10 In a number of large case series the technical success rate was close to 100%, and the long-term success rate (up to 5 years) ranged from 90% to 100%. [10][11][12] Laser energies of various wavelengths including 810 nm, 13 940 nm, 7 980 nm, 14 1320 nm 15 and 1470 nm 16 have been applied to obliterate the GSV. A prospective randomised study 17 comparing the use of 980 nm and 810 nm laser for endovenous obliteration procedures and another one 18 comparing the use of 810, 940, and 980 nm diode lasers showed no significant difference in their effectiveness and complication rate.…”
