When blood leaks backward, it pools in the vein. This causes the vessel to enlarge and elongate. But identifying exactly which valves are leaking is the real challenge. For this reason, it's important to identify the exact source of the problem by having an ultrasound exam prior to treatment. What treatment method is right for you depends on the size and location of your varicose veins.
Surgery is almost always necessary for large varicose veins.
The result is less bleeding and a better cosmetic outcome. Moderate-size veins can be removed using an instrument that looks like a crochet hook. It permits incisions that are virtually invisible. With this method, the vein is injected with a therapeutic solution. The solution causes inflammation in the veins, which stops the flow of blood.
