1 Great saphenous vein patency and endovenous heat-induced thrombosis after endovenous thermal ablation with modified catheter tip positioning  Omar P. Haqqani, MD, Calin Vasiliu, MD, Thomas F. O'Donnell, MD, Mark D. Iafrati, MD  Journal of Vascular Surgery  Volume 54, Issue 6, Pages 10S-17S (December 2011) DOI: /j.jvs Copyright © 2011 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Duplex ultrasound image demonstrates measurements derived from a longitudinal line from the catheter tip position (CTP) projected to a curvilinear line from the superomedial margin of the femoral vein (FV) to the inferomedial margin of the FV in a longitudinal view.

9 Fig 8 Distribution of diameters of the great saphenous vein (GSV) between the preoperative GSV diameter and the length of proximal patent GSV at follow-up. Journal of Vascular Surgery  , 10S-17SDOI: ( /j.jvs ) Copyright © 2011 Society for Vascular Surgery Terms and Conditions

10 Fig 9 Duplex ultrasound image shows the forward thrust of heat, depicted as a flume associated with the ClosureFast radiofrequency ablation catheter. Journal of Vascular Surgery  , 10S-17SDOI: ( /j.jvs ) Copyright © 2011 Society for Vascular Surgery Terms and Conditions

11 Fig 10 Duplex ultrasound image shows the ClosureFast radiofrequency ablation catheter with flume, likely representing expulsion of air/saline contained within the internal channel of the catheter as vapor extending to 1.7 cm. CFV, Common femoral vein; CTP, catheter tip positioning; GSV, great saphenous vein.
