Aplasia of Great Saphenous Vein: A Case Report

Diagrammatic representation and ultrasound images demonstrating the anatomy of the GSV and accessory vein in our case. The GSV in the left limb is absent from the saphenous canal, while in the right limb there is segmental aplasia. (a) Crosssectional view of the common femoral vein showing absence of the SFJ. (b) Crosssectional view of the medial aspect of the upper thigh. The accessory saphenous vein (arrow) is parallel to the femoral vessels. The GSV, which is typically located medial to the accessory vein and femoral vessels, is absent. (c) The accessory vein had significant reflux as demonstrated by the red color and the reverse flow on the Doppler tracings. (d) The GSV is absent in the upper calf. No vein is seen in the saphenous canal medial to the tibial bone (arrow). (e) Cross-sectional view of the GSV in the right limb. It is located in the saphenous canal and is medial to the femoral vessels.
