Lower extremity valve insufficiency, which is the inactivation and decompensation of venous valves, is the most important cause of venous regurgitation, swelling, and weakness in the lower extremities. Currently, the treatment of lower extremity venous valve insufficiency is divided into conservative treatment and surgical treatment. Conservative treatment is to advise patients to avoid prolonged standing or sitting, and to elevate the affected limb at rest to promote venous reflux and reduce tissue swelling. At the same time, oral medications to reduce swelling, such as horse chestnut seed extract, Mai Zhi Ling tablets, calcium hydroxybenzene sulfonate capsules, etc., are used. By improving the permeability of the blood vessels, the venous reflux is promoted and the microcirculation of the tissues is improved. At the same time, it is combined with wearing varicose veins stockings to promote venous reflux and reduce venous tension in the lower extremities. Most patients can be treated conservatively and can get very significant improvement. If the improvement is not obvious or if the symptoms are more severe, surgical treatment methods are available. Commonly used methods include valve repair, which is a repair process that improves valve elasticity, promotes blood return, and prevents regurgitation. This includes intraluminal methods as well as surgical methods, and can also improve valve function through annuloplasty. Therefore, when venous valve insufficiency of the lower extremities occurs, conservative treatment is generally used first, and when conservative treatment is ineffective, surgical treatment is recommended with the help of a specialist.
