The vein’s purpose is to move blood from the body, back to the heart and lungs. Veins are able to perform their function, as they contain one-way valves throughout that open and close to move blood against gravity toward the heart and keep blood from flowing backwards. If these valves do not close properly, or at all, blood pools in the veins, stretching them out, and increases the pressure in the vein. This entire process is how varicose veins and spider veins form causing symptoms of swelling, fatigue, cramping, and pain.
"Once these veins are treated, the blood in these veins finds alternate pathways from surrounding veins, much like a detour on a road. " - Dr. Edward Mackay
What Type of Treatments Close Veins?
There are several different treatments available for varicose veins and spider veins. The basis of all these treatments is closing the malfunctioning veins to prevent further blood flow. Since the blood is not flowing properly through these veins, closing them is the best way to improve circulation and reduce symptoms, but how is this accomplished and where does the blood from these veins go?
Veins are found both superficial, just under the skin surface, and deep within the body muscles. The veins that develop into spider veins and varicose veins are superficial. The majority of the blood is moved to the heart by the deep vein system, so minimal blood is being moved by the superficial veins.
So What Happens When the Veins are Closed?
This is why superficial veins can be treated without any undue consequences. Once these veins are treated, the blood in these veins finds alternate pathways from surrounding veins, much like a detour on a road. Since the superficial veins are responsible for moving a smaller amount of blood than the deep veins, the alternate veins are more than adequate to move blood with improvement in overall circulation in the legs.
