Closure is used, like vein stripping, to eliminate reverse blood flow in the saphenous vein, but without physically removing the vein, and can be performed without general anesthesia. Like other venous procedures, the Closure procedure involves risks and potential complications. Each patient should consult their doctor to determine whether or not they are a candidate for this procedure, and if their condition presents any special risks. Complications reported in medical literature include numbness or tingling (paresthesia) skin burns, blood clots, temporary tenderness in the treated limb.
