The closure procedure uses a small puncture and a catheter and leaves the vein in place, while vein stripping involves incisions in both the groin and calf, through which the vein is removed, according to Sutter Health. Both are used as treatments for varicose veins in the legs.
Both the closure procedure and vein stripping are used when varicose veins are caused by damaged valves in the veins, Sutter Health says. Vein stripping is the more invasive procedure, and it requires a hospital visit and general anesthesia to perform. The closure procedure uses radiant energy to heat and collapse the vein, thereby closing it off and preventing reverse flow and vein swelling. Because it is so much simpler, the closure procedure is usually done in an outpatient setting under local or regional anaesthesia. Both operations have similar rates of success, but the closure procedure tends to be easier to recover from and carries fewer immediate risks.
Varicose veins are veins with damaged valves that swell from the increased blood pressure within, according to Sutter Health. Such damage occurs because of the weight of the blood against the valves in the veins, which are essential to forcing the blood up against the force of gravity.
