It may seem that closing off veins during the treatment of varicose veins and spider veins would worsen circulation, but in fact it can improve circulation. In order to understand why it improves circulation, it is important to recognize the way the vein system functions.
"Closing off veins during treatment of varicose veins & spider veins can improve circulation as the blood reroutes through good veins." - Dr. Almeida
Deep and Superficial Veins. What is the difference?
Veins are thin, floppy structures that move blood from the body back toward the heart with the aid of valves found within the vein. The valves prevent backflow of blood and the contraction of the skeletal muscle moves blood out of the legs. There are both deep and superficial veins, with the deep veins being found deep within the muscle and close to the bones and the superficial veins just below the skin surface and within the soft tissues. The vast majority of blood that is returned to the heart is done so through the deep vein system.
When the valves no longer close properly, blood can backflow in the veins, leading to blood pooling, and increased pressure in the vein causing varicose veins and spider veins. Varicose veins and spider veins can be visible on the skin surface, as these veins are found in the superficial vein system.
What Treatments are Available for Vein Blood Flow?
Due to the unsightly appearance and the myriad of symptoms that varicose veins and spider veins can cause, there are several treatments available, which involve directly stopping blood flow through the diseased vein. Even if a few of these diseased veins are closed with treatment, there are still multiple avenues for blood to flow in the superficial vein system, coupled with the majority of blood flow being returned by the deep vein system to which circulation is not worsened. As the diseased veins are closed off with treatment, the blood is then able to reroute and flow through veins that are working properly, which actually leads to an improvement in the circulation in the legs.
