title: Evaluation of the venous reflux of the great saphenous vein by duplex scan after surgical treatment of the saphenofemoral junction insufficiency.
abstract: OBJECTIVE
  To evaluate the occurrence of reflux from the great saphenous vein by color Doppler ultrasonography in subjects undergoing treatment of insufficiency of the saphenofemoral junction by simple ligation or ligation with section of the saphenous arch.
  
  
  METHODS
  We performed 60 operations (in 45 subjects) of varicose insufficiency of the saphenofemoral junction (SFJ), belonging to the CEAP clinical classification of 2-5, who were randomly divided into two groups. A group called C, with ligature and section of the saphenous arch, and a group called L, with simple ligation of the saphenous vein and no sectioning of its arch. We then investigated the occurrence of reflux from the great saphenous vein in groups C and L through postoperative color Doppler ultrasonography at intervals of six months to one year.
  
  
  RESULTS
  Of the 60 members submitted to the approach of the saphenous arch, 57 were evaluated by postoperative doppler ultrasound, since two subjects (three limbs) did not return and were excluded from the study. The mean age was 54 years, with 93% females and predominance of CEAP classification 2 in 60.5%. Of the 57 operations for the treatment of reflux of the saphenous arch, 43.9% had reflux postoperatively,14.1% in group C and 29.8% in group L (p < 0,05). The relative risk of reflux of the saphenous arch in group L was 2.03 times higher compared with group C.
  
  
  CONCLUSIONS
  the section of the arch of the great saphenous vein causes less postoperative reflux than simple ligation in treatment of insufficiency of the great saphenous vein.
