Compression US of a normal left femoral vein at the level of the bifurcation of the common femoral artery into the femoral artery and the profunda femoris in the upper left thigh. There are no intravascular echogenic masses in the vein suggestive of thrombosis and the thin walled veins compress fully.
A compression US of a normal popliteal vein, which can be seen immediately deep to the popliteal artery.
Distal femoral vein in the lower thigh showing full compressibility.
The left great saphenous vein can be seen arising from the top left side of the common femoral vein, then being compressed, as the probe is slid distally and medially.
Colour Doppler of the popliteal vein (superficial) and artery (deep) at the division of the popliteal vein into the tibioperoneal trunk.
Longitudinal view of the main confluence point of the distal deep veins of the leg to form the tibioperoneal trunk, then the popliteal vein.
Large popliteal vein seen to divide into its main branches as the probe is slid distally.
