At which junction does the GSV join the common femoral vein?

• A. Saphenofemoral junction
• B. Saphenopopliteal junction
• C. Saphello-iliac junction
• D. Saphenofibular junction

Answer: (A)

The correct answer is the saphenofemoral junction, as this is the anatomical site where the great saphenous vein (GSV) drains into the common femoral vein. This junction is significant in phlebology because it is where superficial venous drainage from the lower extremity, represented by the GSV, converges with the deep venous system, which is exemplified by the common femoral vein.

Understanding the function of the saphenofemoral junction is crucial for assessing venous insufficiency and potential varicosities. Proper knowledge of this junction also aids in various medical interventions, including venous mapping and surgical procedures related to varicose veins, as any abnormalities at this junction can have implications for venous return and overall leg health.
