SHORT-TERM AND MIDDLE-TERM RESULTS OF ENDOSCOPIC INTERVENTION USING 1470 NM WAVELEVEL LASER IN TREATMENT CHRONIC LOWER LOWER LIMB VENOUS INSUFFICIENCY
Main Article Content
Abstract
Objective: Evaluate the short-term and medium-term effectiveness of 1470 nm laser endovascular intervention in the treatment of chronic superficial lower limb venous insufficiency at the Department of Cardiology, Thai Nguyen Central Hospital. Study subjects: 121 patients with lower limb vascular insufficiency, with 121 great saphenous veins. Research method: cross-sectional description, retrospective combined with prospective. Results: Chronic lower limb venous insufficiency occurs mainly in women, accounting for 78.5%. After 1 month and 12 months of treatment, it was found that patients with chronic lower limb venous insufficiency treated with 1470nm laser thermal ablation were mainly female, accounting for 78.5%, and the average age of the disease was 78.5%. 56.36 ± 14.16 years old. Occupational risk factors of standing or sitting for ≥ 8 hours have a very high risk of causing disease (81%). The clinical improvement results are clearly reduced after 1–12 months of treatment in terms of bunions, which decreased by up to 85.1% after 1 month; symptoms of leg pain decreased by 80.2%; and no patient still had pain after 12 months. CEAP grading: C2 level decreased to only 9.9% after 1 month and 0% after 12 months of treatment. At levels C3 and C5, they completely decrease after 1 month. The VCSS score decreased from 6.6 ± 1.6 points to 1.32 ± 0.68 points after 1 month and 1.08 ± 0.27 points after 12 months. The results of the Doppler ultrasound were very effective in causing vein occlusion. 100% of the treated great saphenous vein bodies were completely occluded. There were no cases of recurrence during the follow-up period. Complications after intervention are low; only 12.4% have pain along the veins; 6.6% have bruising; 10.7% have dark skin; and 9.9% have skin paresthesia. No patient had inflammation or venous thrombosis after intervention during the follow-up period. Conclusion: The intravenous laser burning method is one of the least invasive interventions, safe, and highly effective, with few complications.
