Bilateral common femoral venous regurgitation is a phenomenon in which the patient experiences regurgitation of blood in the common femoral vein bilaterally due to venous valve insufficiency. Bilateral common femoral vein regurgitation is usually caused by the patient’s lower extremity venous valve insufficiency. When the patient’s venous blood returns from the lower extremity to the heart, the gravity of the blood will cause the venous blood to flow downward, and the venous valves play a role in resisting the downward flow of gravity at this time. When the patient’s venous valves are not functioning properly, it may cause poor venous blood return to the lower extremities, resulting in bilateral common femoral vein reflux, which is often accompanied by bruising and swelling of the lower extremities. In general, patients with bilateral common femoral vein reflux will experience swelling of the lower extremities after prolonged standing or walking. This can be relieved by wearing compression stockings to promote venous return when the patient is active. At the same time, the patient should avoid sitting and standing for a long time, and move the lower limbs appropriately, so as to promote venous blood return through muscle contraction and reduce venous pressure, thus alleviating the phenomena of bruising and swelling of the lower limbs. Patients with bilateral common femoral vein reflux should elevate their lower limbs as much as possible if they have bruising and swelling, and should go to the hospital for examination and treatment if they have not been relieved for a long time.
