Varicose veins of lower extremities are the most common disease in vascular surgery, and daytime surgery has gradually become the mainstream of varicose veins of lower extremities. Superficial venous thrombosis is one of the common complications of varicose veins of lower limbs. Current consensus is that patients with superficial venous thrombosis should be treated with standardized anticoagulant therapy to prevent their progression to venous thrombotic disease.SVT patients need standardized anticoagulant therapy for a period of time, while DS is current mainstream treatment of VV. Will the existence of SVT affect the safety and efficacy of DS of VV, leading a need of changing the treatment strategy and carrying out anticoagulant treatment for SVT before DS on VV patients? To date, there is no research on this issue. Therefore, we conducted this study to comprehensively evaluate the safety, feasibility, perioperative and long-term efficacy of DS in VV patients complicated with SVT, and systematically compared patients who had VV only.
