What percentage of the time does the Great Saphenous Vein (GSV) empty into the Common Femoral Vein (CFV) without additional branches?

The Great Saphenous Vein (GSV) typically drains into the Common Femoral Vein (CFV) in a manner that varies among individuals. The correct percentage indicating how often the GSV empties directly into the CFV without notable additional branches is approximately 45%. This anatomical characteristic is relevant in phlebology as it impacts clinical decisions regarding venous interventions, such as endovenous laser therapy or sclerotherapy. Understanding the prevalence of the direct drainage pattern aids in predicting potential complications or variations in venous anatomy, which are crucial for successful treatment outcomes.

The percentages provided by the other options do not reflect the typical anatomical finding for the GSV drainage and therefore would not be accurate representations of the frequency of direct drainage into the CFV. This emphasizes the importance of knowing the common anatomical variations as a phlebology sonographer.
