title: Use of a new endovenous laser device: results of the 1,500 nm laser.
abstract: BACKGROUND
  A new endovenous laser wavelength (1,500 nm diode laser) in the treatment of great saphenous vein (GSV) reflux was evaluated. We studied the occlusion rate at 6 months and noted possible side effects.
  
  
  METHODS
  In 129 patients, 158 GSVs were treated using the 1,500 nm diode laser. An average linear endovenous energy density of 53.4 J/cm and an average endovenous fluence of 32.21 J/cm(2) were administrated to the vein.
  
  
  RESULTS
  The occlusion rate at 6 months postoperative was 93.3%. Some of the nonoccluded veins closed spontaneously. A postoperative foam treatment was necessary in 3.4% of the treated veins. We found a marked shrinkage of the treated veins. There were limited side effects: moderate or severe ecchymosis in 19%, moderate pain in 1%, moderate periphlebitis in 8.2%, with no paresthesias.
  
  
  CONCLUSIONS
  Endovenous laser treatment of the GSV using a 1,500 nm diode laser is effective and safe. The marked shrinkage of the treated veins can guarantee good long-term results.
