Venous sclerotherapy involves injecting a sclerosing agent and is a relatively good and minimally invasive treatment method. Its advantages include being minimally invasive and even suitable for outpatient surgery, with low costs. However, there are drawbacks; one is that the medication might enter the deep veins, causing deep vein thrombosis. If the dosage is too large, it could reach the lungs, causing pulmonary embolism. Additionally, the medication might seep into surrounding tissues, causing inflammatory reactions. Some patients may experience temporary hyperpigmentation. Surgical treatment is a more traditional method, but it depends on the specific situation. Generally, it causes more trauma than sclerotherapy and usually requires some level of anesthesia. Surgery entails a certain amount of blood loss, and like other methods, it cannot prevent recurrence.
