Brief Summary:

This study will be comparing the treatment of varicose vein tributaries using either foam sclerotherapy or ambulatory phlebectomies. Patients will be randomised to having either ambulatory phlebectomy (group A) or foam sclerotherapy (group B) following treatment of their saphenous vein.

The re-intervention rates, safety, patient experience as well as the cost effectiveness of each intervention will be assessed.

  7. Degree of bruising at 2 weeks [ Time Frame: 2 weeks ]
    Degree of bruising at 2 weeks using a categorical 0-5 bruising scale (0=no bruising; 5=bruising extending beyond treated segment)
