Your veins are responsible for carrying deoxygenated blood from your organs and tissues back to your heart. When they can’t do their job, it can lead to a host of problems ranging from varicose veins to chronic venous insufficiency (CVI). Most skin pigmentation changes arise when CVI isn’t treated and the condition progresses to what’s known as venous stasis dermatitis.
At Dallas Vein Institute, located in Dallas, Texas, interventional radiologist Dr. Dev Batra specializes in treating all types of vein problems. He can determine exactly why you’ve developed skin pigmentation changes and treat your underlying vein issues effectively. Here’s what he wants you to know about the link between vein issues and changes in skin pigmentation.
Your veins all have tiny, one-way valves that help keep blood moving against gravity and upward toward your heart. If these valves fail, the blood flow can move sluggishly and pool around the faulty valve. While this condition can occur at any place in your body, it’s most commonly found in the legs, and it’s referred to as chronic venous insufficiency.
Varicose veins are the most visible symptom of CVI. When blood pools in a weak area of the vein, the vein swells and distorts, creating the ropy reddish or purplish lines you see under your skin.
Additional symptoms include:
The risk for chronic venous insufficiency tends to increase as you age since the valves naturally weaken over time. CVI can also occur if you spend a lot of time either sitting or standing or if you’re overweight. In addition, deep vein thrombosis — a blood clot that forms inside one of your deep veins — contributes to the condition.
If CVI isn’t properly treated, it can lead to venous stasis dermatitis. The dramatic changes in skin color usually indicate that CVI has progressed.
During the initial phases, the increase in pigmentation comes from melanin. However, as fluid pressure within the veins increases, some of the blood leaks from your veins and into your skin, causing more startling color changes.
The latter hyperpigmentation results from deposits of hemosiderin, a pigment created from the breakdown of the iron-rich hemoglobin protein in your blood. The skin takes on a brownish, reddish, or dark bronze color.
If you see discolored splotches on your feet, ankles, or legs, or if large areas of your skin grow significantly darker, it's important to seek medical attention. If CVI and venous stasis dermatitis aren’t treated, you could develop deep vein thrombosis, pulmonary embolisms (clots in your lungs), ulcers that won’t heal, and other health problems.
Obviously, you want to catch vein disease as quickly as possible so it can be treated. Our medical team offers several treatments for varicose veins ranging from sclerotherapy and thermal vein closure to microphlebectomy, the removal of damaged veins through a small incision.
If you already have stasis dermatitis, the goal becomes to relieve symptoms, improve your circulation, and prevent the condition from progressing. Treatments include:
If you’re at risk for vein problems, regular vein checkups are important to prevent venous disease.
