Varicose veins of the lower extremities are a relatively common vascular disease of the lower extremities in clinical practice. If the varicose veins in the lower extremities are in the advanced stage, they will generally appear to be dilated with superficial veins of the lower extremities, and the degree of dilatation is very serious, accompanied by a feeling of heaviness and weakness of the lower extremities. Sometimes severe skin ulcers, dermatitis eczema or hyperpigmentation in the corresponding area will appear, and more typical bamboo-like symptoms will appear, so the later stages of varicose veins should also be treated actively. If the varicose veins are repeated for a long time without treatment, they are also prone to get venous thrombosis, which can easily cause embolism and life-threatening and cause the possibility of pulmonary embolism. Therefore varicose veins try to take specific treatment options, most of the ways used clinically are minimally invasive interventional methods, including radiofrequency ablation or endoluminal vascular cautery, as well as local sclerotherapy compression methods, which have a certain therapeutic effect on late varicose veins.
