How does vein removal help circulation?

I know that removing veins or destroying them is a way to help with vein problems, but won't that just make it more difficult for my blood to circulate in my body? How does destroying or removing veins help me?

We are removing veins that are not functioning properly. Your blood is being trapped in these veins and is not circulating properly. By destroying these non-working veins, your circulation will improve.

Poorly functioning veins are an obstruction to venous blood flow by increasing resistance, turbulence and even reflux (reversed blood flow). By closing or removing these problem veins, blood will flow more efficiently into the normal veins and at a lower pressure. You can grow new veins easily for your entire life just as a tree can grow new branches. By pruning the branches that are only a burden on the circulation, the tree does better. This is the same with your veins and you can never simply run out of veins. As you grow new veins, if they are attached to poorly functioning varicose veins then they will also become damaged and eventually add to the vein problems. A patient with poorly functioning veins would be expected to have too many veins with their lower legs and ankles purple in color due to the multitude of veins as the body keeps adding new veins only to be damaged and eventually stop working. Your circulation is not only the number of veins but whether they are working well. Even a small diameter vein can more a great volume of blood if it is functioning normally and a very large varicose vein may not move blood well at all. For these reasons, treating defective veins improves circulation and helps prevent the progression of varicose veins and venous insufficiency.

Veins appropriately selected for ablation are not functional and impede circulation. Ablation with any technique forces blood into the normal circulation thus enhancing circulation.

It gets rid of the bad veins and diverts the blood to veins that are working correctly.

Great question. This is a question that comes up frequently. When the saphenous veins and its tributaries are refluxing, carrying blood backwards toward the feet, their contribution to the venous circulation is negative. What i mean by that is that any blood that enters these veins goes away from where it is supposed to go. (It's supposed to go towards the heart not the feet). The other veins that are connected to the saphenous vein have to re-circulate the blood they have sent to the feet back up to the heart. The other veins are having to work harder until the saphenous vein and some of its tributaries are closed. The closing of the saphenous vein improves the venous circulation because all the veins are now working to circulate blood to the heart.

Removing varicose veins reduces the venous pressure and the symptoms associated with varicosities, reduces venous blood pooling, swelling, heaviness, and improves the microcirculation in the dermis, just to name a few.

When varicosities are present, the blood is not circulating as the small valves fail to keep the blood going up and back to the mainstream. Hence the blood is "pooling" and stretching out the veins on the surface like a pressure relief valve. Usually there is underlying saphenous vein valve failure which causes these veins. When the those veins are sealed and the varicose veins removed, the blood is circulated back to the deep veins. This in turn improves the pressure and return circulation in this system.

Bad veins are already useless and create several progressive problems. Blood does not return to circulation very easily in dilated incompetent varicose veins, for this reason they can cause pain, ulcers and clotting. When the bad, incompetent, veins are closed, blood is then restored to normal competent veins and back into normal circulation. I hope this helps!
