Be alert to the progress of “varicose veins of lower limbs” as “old rotten legs” 1.What is varicose veins of lower limbs and what are their manifestations? Varicose veins of the lower extremities are a common disease, mostly seen in people who are engaged in long-term physical labor or standing work. The main manifestations are bulging, dilated and tortuous superficial veins of lower extremities; producing symptoms such as soreness and swelling, weakness and heaviness of the affected extremities; in the late stage, there are often swelling, brown pigmentation, eczema, phlebitis and ulcer formation in the skin of calves and ankles. 2.Why varicose veins of lower limbs need early treatment? Varicose veins of lower limbs are a progressive disease, if left untreated, itching, eczema, erosion and ulcers will appear at the varicose veins in the advanced stage and turn into “old rotten legs”. Although early varicose veins only show discomfort such as soreness and swelling of the affected limbs and weakness, this is the best time for treatment and the best period for minimally invasive treatment. Varicose veins not only affect the aesthetics, but also in the advanced stage, the treatment is difficult and risky, which requires a combination of surgical treatment to be effective. 3.How to treat varicose veins with minimally invasive intervention? Interventional minimally invasive treatment of varicose veins is performed under local anesthesia by puncturing the vein with cannula or directly puncturing the varicose vein to inject foam sclerotherapy, and postoperative compression with elastic bandage or wearing elastic stockings to assist in treatment. Compared with the traditional surgical procedure of high ligation and stripping of the saphenous vein, the interventional minimally invasive treatment method has the advantages of less trauma, safety, better efficacy, faster recovery and fewer complications. After minimally invasive treatment, patients can get out of bed immediately without affecting their normal life and work. 4.What tests are required before the minimally invasive treatment? Before treatment, only ultrasound examination of deep and superficial veins of the lower extremities is needed, mainly to understand the usual situation of deep veins and accurately determine the nature, location, scope and degree of lesions, so as to prepare for minimally invasive treatment. 5.How is the effect of minimally invasive treatment of varicose veins in lower limbs? After minimally invasive treatment of varicose veins in the lower limbs, the varicose veins disappear, the symptoms such as soreness, weakness and heaviness of the lower legs improve significantly, and the long-term non-healing ulcers of the skin of the lower legs and ankles can gradually heal, and finally get rid of the “old rotten legs”.
