REVAS - Recurrent Varicose Veins After Surgery
Recurrent Varicose Veins after Surgery (REVAS) is a major complication following surgery, especially varicose vein stripping. The high recurrence rates of secondary varicose veins after surgery have variously been reported from anywhere between 50-65% within 5 years. 
This problem has been known about for a long time!.
In 1929, H.O. McPheeters, M.D., F.A.C.S., The Director of the Varicose Vein and Ulcer Clinic, Minneapolis General Hospital, writes on page 3 in his introduction to” Varicose Veins”:
“The author has often been impressed with the amount of disability that accompanies the extreme and complicated cases of varicose veins and by the fact that such patients may become invalids for life, when under proper care and treatment they might again be made useful members of society. He does not believe that the medical profession as a whole realizes the importance of this condition and how miserable may be the patients so afflicted. The time honored and accepted excision of the offending vein, in the hope of cure, has been unsuccessful in such a large percentage of cases that we must seek new and more effective methods of treatment. The author has often seen varices redevelop and recur even though cared for by the most able surgeons.”
These unacceptably high recurrence rates following surgery have led to research with the aid of Duplex Ultrasound, resulting in a reappraisal of the cause of varicose veins following surgery. It is now thought they are more often due to “neovascularization” rather than a problem of surgical “failure”.
Neovascularization is the development of new venous pathways and studies have shown that this is perhaps the principle cause of recurrence following surgery. 
This new understanding is now leading to the abandonment of surgery and ushering in the new era of techniques involving Ultrasound Guided Sclerotherapy (UGS) and Endovenous Laser Ablation (ELA). 
Studies now give support to the use of the alternative endovenous procedures of UGS and ELA which are less likely to be associated with the problem of neovascularization following surgery that contributes to the high recurrence rates of varicose veins .  
If you have had your varicose veins stripped and they have recurred please come and talk to Dr Kemp. He will understand as it happened to him!
