Varicose veins in the lower extremities are a common vascular disease, with an incidence of about 8% in China. Varicose veins show a slow development process, generally according to the severity of the disease can be divided into six levels: level 1 for capillary dilatation, reticular veins, level 2 for visible varicose veins, level 3 for varicose veins with calf edema, level 4 for varicose veins caused by dermatitis, eczema, pigmentation, etc., level 5 for varicose veins with healed ulcers, level 6 for varicose veins with ongoing ulcers. Varicose veins treatment methods can be divided into medication, elastic stocking treatment, sclerotherapy and surgery etc. Among them, stage 1 and 2 patients can be improved or delayed by medication and elastic stocking, while sclerotherapy can cure most of stage 1 and 2 patients, and most of stage 3 to 6 patients need surgery with sclerotherapy. The vascular surgery department of Weihaiwei People’s Hospital is the first to introduce German imported sclerotherapy polydocanol in our city, which can treat mild varicose veins with only fine needle injection, and has good effect for stage 1 and 2 patients, and sclerotherapy has aesthetic and minimally invasive advantages, especially for patients with cosmetic requirements of capillary dilation and reticular veins. Sclerotherapy injection therapy is suitable for 1st and 2nd degree varicose veins, for heavier varicose veins, especially for patients with grade 4 to 6, laser minimally invasive treatment combined with sclerotherapy is needed. The laser minimally invasive surgery carried out by our vascular surgery department has the advantages of small trauma, fast recovery, aesthetics and low recurrence, which has been widely praised by patients since it was carried out, and patients who need it can go to the vascular surgery department of Weihaiwei People’s Hospital for consultation.
