title: Endovenous laser ablation and concomitant foam sclerotherapy: experience in 504 patients.
abstract: OBJECTIVE
  To investigate the value of endovenous laser ablation (ELA) and concomitant ultrasound-guided foam sclerotherapy (USGFS) in patients with chronic venous insufficiency.
  
  
  METHODS
  During a 6-year period, concomitant USGFS of the varicose veins were performed in 504 out of 610 patients who underwent ELA for truncal or perforating vein insufficiency. In these 504 patients (944 legs; bilateral in 440 patients), the incompetent veins were greater saphenous vein in 615 legs, small saphenous vein in 118 veins, perforating veins in 42 legs, and a combination of these in 169 legs. In all patients, after ELA of the incompetent veins, USGFS was performed for the remaining varicosities with 1-3% polidocanol foam. Patients were followed up clinically and with color Doppler ultrasound at 1, 6, and 12 months.
  
  
  RESULTS
  ELA was technically successful in all cases, although another venous puncture was necessary in 29 legs. Concomitant USGFS was also technically successful in all cases, but one to three additional sclerotherapy sessions were performed in 203 legs with persistent varicosities. During the follow-up, recanalization of the laser-ablated refluxing veins occurred in 16 legs (1.7%) and was treated with repeat ELA or USGFS. Major complications occurred in 1.4% of the treated legs and included skin necrosis and calf vein thrombosis.
  
  
  CONCLUSIONS
  ELA and concomitant foam sclerotherapy is feasible and effective. The procedures are associated with a low complication rate and can be performed in both legs in the same session. Concomitant use of laser and foam may potentially decrease the recanalization rate of laser-ablated vessels.
