In the context of SFJ reflux, what percentage of patients display normal findings in the lower third of the calf?

In the context of SFJ (saphenofemoral junction) reflux, it is observed that a significant majority of patients, approximately 97%, exhibit normal findings in the lower third of the calf. This statistic highlights the fact that while SFJ reflux can lead to significant venous insufficiency and related complications, the majority of individuals assessed do not show abnormal venous changes in the lower calf area. This is crucial for practitioners to know, as it helps delineate which patients may be experiencing significant symptoms due to reflux versus those who may have normal venous anatomy in that region even when reflux is present. Understanding this distribution of findings aids in developing accurate assessments and treatment plans for venous conditions.
