Camera Leg Clamps Surgery For Varicose Veins?

Surgery for varicose veins? - camera leg clamps

My mother told me that she is with the operation of varicose veins in the legs. I suspect that the veins do not close properly when she was dripping with blood on his leg.

In a month, we are brought a camera in the leg have to 6.10 are incisions in the leg, where you have to go and clamp on the vein.

She tries to not sound like much, but I think differently. I try to online information found on this conclusion, but not much.

Is there anyone out there can you explain why this is necessary, the risk of surgery and any other information that you are willing to share?
