Background: Varicose veins are veins that have become enlarged and tortuous. The term commonly refers to the veins on the leg. Endovenous laser therapy (EVLT) is a popular treatment for varicose veins. The study aimed to assess improvement the occlusion rate in the treatment of patients with varicose veins. Patients and methods: this study involved 18 patients with lower limb varicose veins presented at Zagazig University Hospital. All patients were examined clinically to identify symptoms and signs related to venous diseases and duplex ultrasonography were performed. Evaluation was done after one week, one month, 2 months and 3 months following treatment. Results: All patients had improvement in VCSS after EVLA during the first, second and third follow up visits when compared with preoperative scores. The VCSS ranged from 5 to 15 before the procedure, with a mean of 8.89, ranged from 1 to 6 at the first follow up visit with a mean of 3.4, ranged from 1 to 5 at the second follow up visit with a mean of 2.5 and ranged from 0 to 4 at the third follow up visit with a mean of 1.6. CIVIQ in the legs of studied group: Pre-operative was14.42 ± 7.29 while after 6 month was 7.64 ± 4.62. Only Ecchymosis in 2 limbs (6%), Paresthesia at leg in 3 limbs (9%), Phlebitis 4 limbs (12%),Skin burn in one limb (3%)and Incomplete occlusion in one patient(4%). Conclusion: Higher energy EVLA of varicose veins showed faster recovery attributable to the decreased pain, immediate ambulation and faster return to everyday activities. Patients experienced symptom relief after the procedure with decrease the VCSS and CIVIQ in both.
