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.

ABSTRACT

PURPOSE: To assess efficacy and safety of imaging-guided radiofrequency ablation (RFA) of Osteoid Osteoma (OO) in both typical and atypical sites. METHODS AND MATERIALS: Between January 2014 and March 2019, 102 consecutive percutaneous RFA were performed and retrospectively reviewed. The procedures were performed using a RFA bipolar ablation system (Covidien, exposed tip of 0.7-1cm), under Computed Tomography (CT) guidance or using a navigation system (Masmec) under CT and Cone Beam CT (CBCT) guidance. Patients were followed up over 24 months. Clinical success and recurrences were considered on the base of established criteria. In patients with clinical failure and/or imaging evidence of relapse, retreatment was considered. RESULTS: Administered power per-procedure was ≤8 W (mean temperature, 90°C). The pre-procedure average value of visual analog scale (VAS) was 8.33+/-0.91. Primary and secondary success rate 96.08% (98/102) and100% (102/102), respectively. No major complication was described. Technical success was proved in every patient by CT scan acquisition after needle positioning. Relapse and tumour location were significantly correlated (p-value = 0.0165). The mean dose-length product was 751.55 mGycm2. Advanced bone healing was noted in 68 lesions after 1y-follow up and in 86 lesions after 2y-follow up. CONCLUSION: Imaging-guided percutaneous RFA is a highly effective technique for OO, both in typical and atypical sites. CT or CBCT guidance, navigation systems and operator experience grant the technical success, which is the most crucial parameter affecting outcome.
