Spider and reticular veins indicate that the blood flow from your heart to your limbs is being interrupted. You’ll notice red, blue, or purple looking veins under the skin, often in a patch of twisting color. Although that can sound scary, this condition is harmless, even if it is quite noticeable.
Veins like this belong to a disease state known as venous hypertension or chronic venous insufficiency (CVI). It’s a disorder affecting vein function.
A normal vein conducts blood flow from the heart to your extremities, working hard against gravity to push nutrition and oxygen to all the corners of your body. As the body sends blood outward from the heart, each delicate vein structure has a value that opens as blood flows through and then shuts to prevent a backwash of pooled blood. When that vein malfunctions, it can begin to twist, resulting in three types of vein conditions.
Spider veins are the smallest of the CVI conditions. Reticular veins are larger than spider veins. Finally, varicose veins can be quite large, noticeable, and even painful. They require a different level of treatment beyond what we use for spider and reticular veins.
Sclerotherapy is the best method for treating the first two of these veins: spider and reticular veins.
