Unifuse® catheters available are 5F with either 45 cm or 90 cm lengths in combination with 5cm, 10cm or 15cm long infusion patterns. The appropriate Unifuse® catheter will be selected and deployed through the introducer sheath and advanced to within 2cm of the junction or perforator at the upper limit of incompetence or the top of the incompetent segment in the case of segmental reflux. The catheter will be aspirated to ensure correct position and flushed with normal saline. Each tributary system will be cannulated as was the case in the FS group.
