title: Clinical results of endovenous LASER ablation (EVLA) using low linear endovenous energy density (LEED) combined with high ligation for great saphenous varicose veins.
abstract: OBJECTIVE
  This study was designed to analyze the efficacy and complications in endovenous LASER ablation (EVLA) with 1470 nm diode lasers using low linear endovenous energy density (LEED) combined with high ligation for varicose veins of the great saphenous vein (GSV).
  
  
  METHODS
  One hundred and sixteen limbs of 102 patients were analyzed using 6 W with 2 mm/s constant pullback speed delivered by 30 J/cm LEED. The SFJ was ligated with a small inguinal incision. The complications and status of the GSV were checked at 1 and 6 months postoperatively.
  
  
  RESULTS
  The occlusion rates for the GSV were 98 (84.5 %) at 1 month and 116 (100 %) at 6 months, postoperatively. The rate of partial occlusion was higher in males than in females (p = 0.004). There were 2 DVT, 27 feelings of the cord (23.3 %), and 36 numbness at the knee area (31.0 %) at 1 month, and 3 feelings of the cord (3.4 %) and 6 numbness of the knee (8.6 %) at 6 months postoperatively. The diameter and depth of the GSV did not affect the rates of feeling of the cord or numbness (p = 0.728, 0.208, 0.247, 0.884, respectively).
  
  
  CONCLUSIONS
  EVLA with a 1470-nm diode laser using low LEED combined with high ligation for the GSV has lower complication rates and higher occlusion rates of GSV.
