In clinical practice, deep veins do not varicose, but usually superficial veins do. It is important to note that superficial varicose veins are mostly caused by the insufficiency of the patient’s deep vein valves, so it is important to make a good clinical distinction between the two. Generally, if a patient has a superficial varicose vein, it is necessary to clarify whether the patient has abnormalities in the deep vein valves, and then targeted treatment measures can be taken, for example, if the patient has a superficial varicose vein and the deep vein valves are incompetent, then deep vein valve repair can be performed, followed by superficial varicose vein aspiration, so that the patient can be cured. It is important to note that generally the superficial venous system is returning to the deep venous system and both are one and the same. Therefore, it is important to look at both as a whole during the diagnosis and treatment process so that the patient can be treated.
