ABSTRACT

BACKGROUND: Iliac vein compression (IVC) is a common condition in patients with varicose veins (VVs) of the legs. IVC has been classified into three grades in previous studies. Grade II IVC is defined by >50% stenosis without the development of collateral circulation. The purpose of the present study was to investigate the outcomes of radiofrequency ablation (RFA) for patients with VVs combined with grade II IVC. METHODS: A retrospective analysis was conducted of 339 patients who had undergone RFA for VVs of the left leg from March 2017 to January 2019. Duplex ultrasonography, computed tomography venography, and venography were performed to evaluate for grade II IVC. All the patients were divided into two groups. Group 1 included patients with VVs only, and group 2, patients with VVs combined with grade II IVC. Propensity score matching was used to ensure an even distribution of confounding factors between groups. The venous clinical severity score (VCSS) and chronic venous insufficiency questionnaire (CIVIQ) score were recorded during the 12-month follow-up. Occlusion of the truncal veins was evaluated using duplex ultrasound scans. RESULTS: Using 1:1 propensity score matching, 50 pairs of patients were enrolled in the present analysis. The average age of groups 1 and 2 was 58.7 ± 13.1 and 60.1 ± 7.1 years, respectively. The VCSS had decreased significantly from baseline to 12 months postoperatively (group 1, from 5 to 1; group 2, from 4 to 1; P < .01). A significant increase in the CIVIQ score was found between the baseline and 12-month evaluations for both groups (group 1, from 62.5 to 69; group 2, from 63 to 70; P < .01). The truncal occlusion rate was 98% in both groups at 12 months. No significant differences were found between the two groups in the VCSS, CIVIQ score, procedure complications, or occlusion rate during the 12-month follow-up. CONCLUSIONS: RFA is effective for patients with VVs combined with grade II IVC.

ABSTRACT

OBJECTIVE: Post-procedure limb compression, hitherto routine following open varicose vein surgery, has been extended to endovenous procedures. However, no robust evidence exists to support this practice. Most of the previous studies have focused on the ideal duration of compression. This study evaluates the clinical and patient reported outcomes with and without post-procedure leg compression following radiofrequency ablation (RFA). METHODS: This single centre, prospective, non-inferiority randomised controlled trial recruited adult patients, into two groups (A: RFA with compression stocking for two weeks, B: RFA alone). The primary outcome was ultrasound determined target vein obliteration at 12 weeks. Secondary outcome measures included a Quality of Life (QoL) score [Aberdeen Varicose Vein Severity Score (AVSS) and Revised Venous Clinical Severity Score (RVCSS)], patient satisfaction, pain score, and complications. RESULTS: In total, 100 consecutive patients were recruited (A: 51; B: 49) classified as clinical class C2-C6 of the Clinical-Etiological-Anatomical-Pathophysiological (CEAP) classification. At 12 weeks the occlusion rate of the target vein was similar in both groups at 98% (n = 47) and 98% (n = 45), respectively (p = 1.0). There was no statistically significant difference in mean AVSS 6 vs. 5.0 (mean difference -1, 95% CI -2 - 3, p = .57) and mean RVCSS 3 vs. 4 (mean difference 1, 95% CI -1 - 2, p = .46) scores at 12 weeks. Comparable patient satisfaction scores were observed (p = .72) and pain score 2.0 vs. 2.0 (p = .92) were achieved in both groups. Two patients in each group developed deep vein thrombosis at two weeks follow up (p = 1.0 for above the knee and p = 1.0 for below the knee). CONCLUSION: The clinical and patient reported outcomes following RFA without compression are no worse than with compression. This trial supports the conclusion that the widely practised use of compression after RFA adds no clinical benefit for the patients. However, a much larger study, preferably a multicentre trial, may be required to confirm this conclusion.
