Table 5. Imaging Follow-Up and Outcomes of RFA Ablation of Great Saphenous Vein with ClosureFast Catheter.
| Author, Year, Country | Sample | Treatment Success, Follow-UP | ≤ 3 Months | 6 Months |
|---|---|---|---|---|
| Calcagno 2009 Pennsylvania, US (78) | 246 GSV (<12 mm), 96 GSV (≥ 12 mm) | • Occlusion of treated vein on duplex ultrasound at 2 wks and at 6 months • Closure defined as no vein segments open in the treated vein, partial closure defined as vein with some closed and some patent sections and patent was a vein open on • Mean follow-up of 4 months (range: 2 - 11 months) |
Complete closure for 98% (n=112) for veins ≤ 12mm and 100% (n=43) for veins > 12mm. Follow up was unavailable for 46% and 45% of the two groups |

DU refers to Duplex ultrasound: SSV, small saphenous vein; VAR, veins at risk
