Effect of Saphenous Vein Diameter on Closure Rate With ClosureFAST Radiofrequency Catheter

Abstract

Vein diameter >12 mm had no effect on closure rate with the ClosureFAST catheter.

Three-year European follow-up of endovenous radiofrequency-powered segmental thermal ablation of the great saphenous vein with or without treatment of calf varicosities

“…Such high ablation rates can even be achieved by RSTA with vein diameters Ͼ12 mm. 3 In our study, only 5 of 256 legs (2.0%) presented with recurrent axial reflux.…”

“…1,2 These findings have been corroborated recently, describing occlusion rates of 98% to 100% at 6 months of follow-up, further demonstrating that a vein diameter Ͼ12 mm is not related to a decreased ablation rate. 3 In addition, a prospective randomized trial proved that the side effect profile of RSTA compared favorably with endovenous laser ablation using a 980-nm diode laser and typical blunt-tipped bare fibers. 4 Because of the widespread use of RSTA, midterm results of the first clinical trial of RSTA, including the durability of once achieved GSV occlusions and the postinterventional course of clinical signs and scores, are of special interest.…”

Midterm Results of Radiofrequency Ablation for Incompetent Small Saphenous Vein in Terms of Recanalization and Sural Neuritis

“…Among other variables, SSV diameter seems to have no correlation with recanalization rate. Vein diameter was reported to have no effect on closure rate with the RFA catheter since the introduction of tumescent infiltration . With tumescent anesthesia, the vein can be compressed against the catheter, so direct contact of veins larger than maximal catheter diameter can be achieved.…”

Is radiofrequency ablation of varicose veins a valuable option? A systematic review of the literature with a cost analysis

“…Across all studies, the occlusion rates at less than 3 months were usually 93%-100%, 11,13,15,25,31,36,37,41 with a weighted average of 98% (weighting was performed according to the number of legs treated in each study). The venous occlusion rate at 6 months was reported as being close to 90% in 4 studies included in the MAS review 20 but appeared to be higher in more recent studies, 98.6%-100%, 8,26,28,35 for a weighted average of 98.8%. Longer-term follow-up results (≥ 1 yr) were rare.…”
