What percentage of the time do separate GSV and AASV communicate with the Common Femoral Vein (CFV)?

The communication between the Great Saphenous Vein (GSV) and the Accessory Saphenous Vein (AASV) with the Common Femoral Vein (CFV) is an important concept in phlebology. The correct percentage, which is 1.9%, is based on anatomical studies that observe these venous arrangements.

This percentage reflects the occurrence of a direct communication between the separate GSV and the AASV with the CFV, illustrating that this is a relatively uncommon anatomical variation. In practice, understanding the frequency of these communications can help sonographers when assessing venous systems, as it can impact the evaluation and treatment of venous diseases.

The other percentages suggest a higher frequency of communication that does not align with the established anatomical variations typically reported in clinical studies. This understanding is crucial when performing assessments with ultrasound, as it aids in identifying the pathways for venous return and potential sites of pathology.
