Reflux origin of the insufficient small saphenous vein by duplex ultrasound determination and consequences for therapy considering the saphenopopliteal junction type.

Objective: The reflux pathophysiology of the saphenofemoral junction (SFJ) of the insufficient great saphenous vein (GSV) has already been investigated and stratified. These results are still lacking for the small saphenous vein (SSV). The aim of the study was to analyze the pathophysiology of the saphenopopliteal junction (SPJ) in case of refluxing SSV.
