Abstract
Objective: To investigate clinical characteristics, venous ultrasound and interventional techniques in patients with great saphenous vein (GSV) insufficiency treated with radiofrequency ablation (RFA) and the CR45i catheter. Subject and method: A cross-sectional description study was performed on 232 patients with 352 legs with chronic lower extremity venous insufficiency manifested by reflux flow > 0.5 seconds on Doppler ultrasound and with clinical grading from C2 to C6, were treated with radio frequency ablation at Hanoi Heart Hospital from September 2017 to December 2020. Patients were asked about their diseases, clinical examination, lower limb venous Doppler ultrasound, ultrasound-guided intervention. Result: The average age of the study subjects was 55.4 ± 13.1; among them, the majority of patients were women, accounting for 82.8%. The average BMI of the subjects was 20.9 ± 2.4. The most common physical symptoms were calf strain (96.3%), ankle pain (84.9%), night cramps (80.4%), and sensory disorders (74.1%) and leg edema (57.7%). The main clinical classifications were C2 (75.3%) and C3 (18.2%). The average VCSS score was 7.9 ± 1.4; The average CIVIQ-20 score was 44.5 ± 3.9. The average diameter near the GSV loop was 7.7 ± 1.1mm; Mean reflux time was 1.9 ± 0.7 seconds. The average length of the treated GSV segment was 35.5 ± 5.9cm with an average burning time of 449.8 ± 71.3 seconds. Conclusion: The patients' functional symptoms are diverse and the main clinical classification is CEAP 2 and 3.
