What is evidenced if the CFV is compressible during an examination?

The compressibility of the common femoral vein (CFV) during an examination indicates normal venous function. When veins are healthy and free from obstructions, they compress easily when pressure is applied during an ultrasound examination. This ability to compress is a vital characteristic of the normal functioning venous system, showing that the venous walls are flexible and that no significant pathological changes, such as venous thrombosis or obstruction, are present.

In clinical practice, when assessing for deep vein thrombosis (DVT), the inability to compress the CFV can suggest the presence of a thrombus, which would block the normal flow and functionality of the vein. Conversely, the presence of full compressibility supports the conclusion that the veins are functioning as expected, providing reassurance about the absence of venous disease.
