What is the difference between minimally invasive surgery and traditional surgery for varicose veins of lower limbs?

In minimally invasive surgery for varicose veins of lower limbs, the blood flow of veins is increasing. Inject vascular sclerosing agent into the blood vessels of the calf, cut off the upward pressure of blood flow, then wrap it up and squeeze the excess blood (varicose veins) upward. There is no blood during this period, so I can't see the principle of varicose veins. Veins are divided into deep veins and shallow veins, which will not cause limb ischemia.

The traditional surgical treatment is ligation and resection of great saphenous vein. Surgical treatment is traumatic, bleeding is much, and unclean veins will recur. And the pain is great, the recovery time is long, and the anesthesia risk is high.

Minimally invasive surgery, the incision is small but expensive, ranging from 30 thousand to 50 thousand
