Endovenous laser ablation of great saphenous vein with ultrasound-guided perivenous tumescence:early and midterm results

摘要

Background Endovenous laser ablation (EVLA) is an improved method to treat varicose great saphenous veins (GSV)with a high satisfactory rate.This study aimed to evaluate the efficiency and safety of treatment by EVLA procedures with ultrasound-guided perivenous tumescence.Methods Thirty-one patients (31 limbs) with symptomatic varicose vein primary to chronic venous insufficiency (CVI) treated with EVLA were prospectively studied.The entire procedure was performed under ultrasound-guided tumescent local anesthesia.The patients were evaluated with a 18 month follow-up postoperation using clinical examination and venous duplex ultrasonography.Pain scores and quality of life (QOL) were recorded using visual analog scale (VAS) and the chronic venous insufficiency questionnaire (CIVIQ) at 1 week,1 month,and 12 months after operation.Results All patients tolerated EVLA procedure well.The overall success occlusion rates of GSV were 92％,94％,and 94％ at 1,12,and 18 months follow-up,respectively.The score of CIVIQ one week preoperation was 69.14±11.44 while that of CIVIQ one month postoperation was 85.32±4.89.The life quality has significantly improved after the operation of EVLA (t=12.71,P ＜0.05).The VAS one month after treatment was lower than 1 week before therapy (t=8.048,P ＜0.05).Major complications such as deep vein thrombosis and skin bums were not found.Most of the complications were minor and improved quickly.Conclusions This refinement type of EVLA procedure is a safe and effective treatment with a high satisfaction rate; it displayed noteworthy features including shortening hospitalization,early ambulant activity,and preferable occlusion rates.
