Abstract

Background: Chronic venous insufficiency (CVI) is a prevalent condition that significantly impacts quality of life and reduces work productivity. In Khanh Hoa, this is a relatively new technique that has been applied recently to meet the increasing demand of high-tech medical treatment among the local population.


Objectives: To evaluate the clinical characteristics and treatment outcomes of endovenous laser ablation (EVLA).


Methods: A retrospective case series study


Results: There were 73 patients diagnosed with Chronic Venous Insufficiency (CVI) and ultrasound-confirmed saphenous vein reflux and treatmented with Endovenous Laser Ablation (EVLA) at Khanh Hoa General Hospital from July 2024 to September 2025. The mean age of the study population was 57.4 ± 11.9 years, with a predominance of female patients (65.8%). Most patients had a relatively high mean body mass index (23.8 ± 2.1 kg/m²) and occupations requiring prolonged standing for more than 4 hours per day (61.6%). Before intervention, the majority of patients were classified as Clinical-Etiology-Anatomy-Pathophysiology (CEAP) C2 (47.9%) and C3 (50.7%), with a mean Venous Clinical Severity Score (VCSS) of 5.5 ± 2.2. One week after intervention, 100% of patients experienced complete resolution of pain, and the mean VCSS significantly decreased to 1.6 ± 0.6 (p < 0.001). According to CEAP classification, 95.9% of patients improved to C0. Complete venous occlusion was achieved in 100% of cases on Doppler ultrasound. Reported complications were infrequent and mild, including ecchymosis (1.4%), skin burns (1.4%), and pain or dysesthesia (2.7%).


Conclusion: Endovenous laser ablation (EVLA) is a safe and highly effective treatment
