Endovenous laser ablation of great saphenous vein with ultrasound-guided perivenous tumescence: early and midterm results / 中华医学杂志(英文版)

ABSTRACT

<p><b>BACKGROUND</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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 burns were not found. Most of the complications were minor and improved quickly.</p><p><b>CONCLUSIONS</b>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.</p>
