Varicose vein study shows radiofrequency ablation causes less post-operative pain
Date:5/17/2010

advises the National Health Service - approved their use."

Key findings of the study included:

  • Average pain scores for the first three days after surgery were 26.4 on the zero to 100 scale for the RFA group and 36.8 for the EVLA group.

  • The average scores for the first 10 days after surgery were 22.0 for the RFA group and 34.3 for the EVLA group.

  • Patients treated with RFA used an average of 8.8 analgesic tablets during the first three days and 20.4 over the first ten days. This was much lower than the 14.2 and 35.9 used by the EVLA group.

  • Sixty per cent of the RFA group and 50 per cent of the EVLA group returned to normal activities after three days, with 77 and 74 per cent respectively resuming normal activities within seven days. Return to work figures were similar for both groups.

  • Only two major complications were observed. A patient in the RFA group suffered a pulmonary embolus two weeks after surgery and a patient in the EVLA group suffered a lymphatic leak.

  • The most common minor complications were tingling, pricking or numbness (10 per cent), vein inflammation (six per cent) and skin staining (six per cent).

  • There was little difference in clinical and quality of life scores between the two groups six weeks after surgery.

"Our study showed that patients experience less post procedural pain with the VNUS ClosureFAST than the 980nm EVLA" says Professor Davies.

"Newer radial fibres and longer laser wavelengths have been developed for EVLA and are likely to replace the 980nm bare tip laser fibre. We await the results of randomised trials using these with interest."
