Abstract: Objective: To investigate the clinical value of intracavitary laser closure (EVLA) combined with foam sclerotherapy (FS) in the treatment of great saphenous vein varicosity (GSVV). Methods: A retrospective analysis of 85 cases (105 legs) were made from January 2016 to August 2019, who had minimally invasive treatment of great saphenous varicose veins combined with foam sclerotherapy injection technology, complications, postoperative follow-up of great closure rate of the great saphenous vein and relapse were observed, and its therapeutic effect was evaluated. Results: There were no pulmonary embolism or drug allergy complications in this group during and after the operation. 1 week after the operation, the symptoms of lower extremity such as acid and fatigue disappeared, and there were no signs of venous thrombosis such as gastrecnemius pain and lower extremity swelling. Two cases had abnormal skin sensation and recovered after 3 months. Local inflammatory mass appeared in 2 cases and was cured after physiotherapy. During the follow-up period of 3~24 months, the main trunk closure rate of the great saphenous vein was 100%, 83 cases were cured, and 2 cases of residual varicose veins in the lower leg were cured by re-injection of sclerotherapy. Conclusion: The treatment of varicose great saphenous vein by intracavitary laser closure combined with foam sclerotherapy can achieve the clinical effect of less trauma, fewer complications, faster postoperative recovery and higher cure rate.
