title: Natural history of the great saphenous vein stump following endovenous laser therapy.
abstract: BACKGROUND
  Little is known about the ideal residual length of the great saphenous vein (GSV) stump and its potential role in complications such as acute deep venous thrombosis (DVT) and recanalization. This study was designed to learn about the natural history of the residual GSV stump length following endovenous laser treatment.
  
  
  METHODS
  Prospective data were collected from 50 limbs of 50 patients over an 11-month period. Clinical assessment and duplex ultrasound were performed preoperatively, at 24 hours and at 3 months after the procedure.
  
  
  RESULTS
  The residual GSV stump decreased in length from a mean of 15 mm at 24 hours to 13 mm at 3 months after the procedure. None of the patients developed acute DVT or proximal recanalization when the laser tip was positioned 28 mm distal to the saphenofemoral junction.
  
  
  CONCLUSIONS
  Endovenous laser therapy of the GSV for symptomatic reflux is safe and effective. The residual GSV stump decreased in length over a 3-month period.
