Varicose veins (VV) of lower extremities are considered as common diseases in outpatient and inpatients. Nearly 25% of the global adult population suffer from VV, of which, the prevalence of VV in China reaches 8.9%, affecting more than 100 million people [Compared to inpatient surgery (IS), which previously used for treating VV, day surgery (DS) offers higher medical efficacy and lower healthcare costs [Superficial venous thrombosis (SVT) is a frequent complication of VV. It manifests as pain, erythema, and typically a palpable nodular mass. Although SVT can occur independently, VV remains the primary risk factor. Previous studies have indicated that the likelihood of SVT in VV patients ranges from 4 to 59%, and up to 80% of SVT cases are accompanied by VV [Most scholars believe that VV patients combined with SVT require a period of anticoagulant therapy before surgical treatment can be performed; however, the evidence supporting this viewpoint is not of high grade (Class IIa, grade C) [SVT patients typically require a period of standardized anticoagulant therapy, while DS is currently considered the mainstream treatment for VV. However, it remains unclear whether the presence of SVT affects the safety and efficacy of DS for VV patients, which may lead a change in treatment strategy and the implementation of anticoagulant treatment for SVT prior to DS. To date, there is no research on this issue.It remains unclear the impact of SVT on the efficacy of DS for varicose veins patients. To comprehensively evaluate the feasibility and efficacy of DS for VV patients complicated with SVT, we conducted this study and systematically compared it to patients with VV only. Considering particles of thrombus of thigh can be propagated into the deep venous system by pushing the device forward through the affected vein, only patients with SVT below knee were included in our study.
