Radiofrequency ablation for the treatment of great saphenous venous insufficiency using a newly developed VENISTAR catheter : A preliminary study
OBJECTIVES: This study was aimed to assess the preliminary outcomes of radiofrequency ablation (RFA) using a newly developed catheter (VENISTAR) for the treatment of incompetent great saphenous veins (GSVs).
METHODS: In this prospective observational study, endovenous RFA using a VENISTAR catheter was performed on 16 saphenous veins in 12 patients between August and November 2019. Patients' pre- and post-procedural data were recorded. Doppler ultrasound imaging and clinical evaluation were performed at 1 week and 1, 3, and 6 months to determine the efficacy and safety of the treatment.
RESULTS: Technical success and complete closure of the targeted GSVs immediately after the procedure were observed in all 16 limbs (100%). However, one patient (one limb) was found to have partial occlusion without significant reflux after 1 week of follow-up. Kaplan-Meier analysis yielded a complete occlusion rate of 93% at 6 months of follow-up. The Venous Clinical Severity Scores at the time of all follow-up were significantly lower than those at baseline (3.3 ± 1.1 at baseline to 0.6 ± 0.6, 0.3 ± 0.6, 0.1 ± 0.4, and 0.2 ± 0.4 at 1 week and 1, 3, and 6 months, respectively) (p < .001). Mild post-procedural pain was noted in 7 and 4 limbs at 1 week and 1 month, respectively. Grade 1 ecchymosis over the ablated segment was noted in 5 (35.7%) of 14 limbs at 1-week follow-up.
CONCLUSIONS: Endovenous treatment of GSV insufficiency using a new VENISTAR radiofrequency catheter has been shown to be feasible, effective, and safe throughout the 6-month follow-up.
