Though caused by the same venous disorder, varicose veins and spider veins have some distinct differences.
Though many patients don’t realize it, “varicose veins” and “spider veins” aren’t synonyms — they’re two distinct conditions with different sets of symptoms. Although caused by the same underlying venous disorder, varicose veins and spider veins differ in several ways.
For one, varicose veins are larger, usually exceeding three millimeters in diameter. They typically appear as blue- or purple-colored bulging ropes along the legs, feet, or ankles. They can be swollen and visible on the legs, but sometimes are not close enough to the surface of the skin to be seen. Other symptoms of varicose veins include aching, throbbing, heavy feeling in the extremities.
In contrast, spider veins are typically one millimeter in diameter. They appear as web-like clusters of blue or red veins on the surface of the skin. Unlike varicose veins, spider veins do not bulge out from under the skin. Though they crop up most often on the legs, spider veins develop on the face, too. Spider veins rarely cause symptoms, so when patients seek treatment, it’s usually for cosmetic reasons.
Despite these differences, both vein conditions stem from a fault in the venous system in the legs.
What Causes Varicose and Spider Veins
Veins and arteries carry blood throughout the body, replenishing it with oxygen and nutrients. Within each leg vein is a one-way valve that pumps blood back to the heart. A variety of factors, including age, weight, and heredity, can cause these valves to malfunction.
Unable to counter the force of gravity and push blood upward, the faulty valve lets the blood collect in the vein, causing the vein walls to rise from underneath the skin due to excess pressure and pooling of blood. When that happens, varicose veins or spider veins emerge.
Because the blood has to travel a longer distance between the extremities and the heart, varicose veins and spider veins appear mostly on the legs. If spider veins show up on the face, it’s probably due to a burst blood vessel, possibly as a result of excessive sun exposure.
Preventing Varicose & Spider Veins
Many factors contribute to the formation of varicose veins and spider veins. Heredity, age, and gender (women tend to get varicose and spider veins at a higher rate than men) all play a significant role. While individuals cannot alter those factors, they can control other influences that contribute to the development of varicose veins and spider veins. Here are four tips that can help to prevent varicose veins and spider veins.
Treating Varicose & Spider Veins
These prevention tips may also alleviate the discomfort of varicose veins. But if varicose veins become too painful or spider veins are a source of insecurity, patients can choose from several minimally invasive treatments to treat the conditions.
Sclerotherapy, a procedure in which a solution is injected into the vein to close it off, is the preferred therapy for spider veins and smaller varicose veins. Another treatment option is radiofrequency ablation. In this procedure, a thin catheter inserted into the vein that blasts the vein with radio waves. The heat collapses the vein as the blood is accommodated by healthier veins.
At the Center for Vein Restoration, our specialists perform those procedures and others to address varicose veins and spider veins. All require little or no anesthesia, and patients resume their normal activities within hours.
