What are Spider Veins?

Spider Veins gaining their name from their unique look and the tendency to spread as individuals age, spider veins can appear anywhere on your body. Like varicose veins spider veins are veins that are much smaller that have become dilated and do not properly push the blood through the valves in the veins back up to the heart. This leads to the pooling of blood in these smaller superficial (close to the skin) veins.


• Swelling in the legs
• Heaviness in the legs
• Tiredness in the legs


Like varicose veins, spider veins are caused by a condition known as venous insufficiency where the vein is unable to fully return blood back up to the heart leaving the blood to backup in a given area.


Physical examination by your vascular surgeon while standing to check for swelling. Your surgeon may also request ultrasound testing to check the functionality of the valves in your veins.


Using an ultrasound to direct the placement of a small needle the provider will inject a sclerosing agent into the spider vein that will help the vein break down naturally and be reabsorbed by the body’s natural processes. The sclerosing agent causes the veins to collapse and for blood to reroute through healthier veins.
