1 Duplex ultrasound scan findings two years after great saphenous vein radiofrequency endovenous obliteration  Olivier Pichot, MD, Lowell S Kabnick, MD, Denis Creton, MD, Robert F Merchant, MD, Sanja Schuller-Petroviæ, MD, PhD, James G Chandler, MD  Journal of Vascular Surgery  Volume 39, Issue 1, Pages (January 2004) DOI: /j.jvs

2 Fig 1 Sonogram and cartoon showing an open saphenofemoral junction with a short patent segment above an otherwise occluded great saphenous vein (GSV). The superficial external pudendal (SEP) vein is patent with normal, prograde flow through the SFJ. CFV, Common femoral vein. Journal of Vascular Surgery  , DOI: ( /j.jvs )

3 Fig 2 a, Pretreatment duplex image showing midthigh great saphenous vein reflux. Note diameter markers. b, Same vein level at 6 mo, showing diameter reduction, vein wall thickening, and a narrow, irregular, echolucent lumen without flow. c, Same level at 2 years, now seen as a featureless hyperechogenic stripe with further diameter shrinkage and no discernible lumen. Journal of Vascular Surgery  , DOI: ( /j.jvs )

4 Fig 3 Sonogram and cartoon showing superficial external pudendal (SEP) vein prograde flow through an ultra short, patent, great saphenous vein (GSV) segment and a refluxing external pudendal (ExP) vein, originating directly from the common femoral vein (CFV), that bypasses a competent saphenofemoral junction to fill posterior thigh varicosities.
