Spider Veins
Fine red and purple vessels at the skin’s surface — usually harmless, occasionally a clue to something deeper, and very treatable either way.
What spider veins are
Spider veins — the medical term is telangiectasia — are small dilated blood vessels visible just beneath the skin. They appear as thin red, blue, or purple lines in web-like or branching patterns, most often on the thighs, calves, and ankles. Unlike varicose veins, they lie flat against the skin and do not bulge.
Most spider veins are a surface finding. But in some patients they are fed by leaking valves in deeper veins — the same process behind chronic venous insufficiency. Distinguishing the two changes the treatment plan, which is why we evaluate before we treat.
Symptoms
- Visible red, blue, or purple vessels in clusters or branching lines
- Occasionally mild burning, itching, or tenderness over the veins
- Self-consciousness about the legs — many patients stop wearing shorts or skirts
When spider veins come with aching, heaviness, or ankle swelling, that combination suggests an underlying vein problem worth investigating rather than a purely cosmetic one.
Causes and risk factors
Heredity leads the list, followed by pregnancy and hormonal changes, prolonged standing or sitting, age, sun exposure (for facial vessels), and minor skin trauma. Women develop spider veins more often than men, and they frequently become more numerous over time if the contributing factors persist.
What happens if they go untreated
Spider veins themselves are rarely dangerous. Untreated, they tend to slowly multiply and darken rather than fade. The more important question is what may be underneath: when spider veins are fed by venous reflux, the underlying condition can progress toward swelling and skin changes even while the surface vessels look stable. Clusters around the inner ankle in particular deserve an ultrasound look.
There is also the quieter cost: patients tell us they have avoided shorts, skirts, or the beach for years. That alone is a reasonable motive to seek treatment — you do not need a medical justification to want your legs back.
How we diagnose them
Your consultation begins with an examination and, when the pattern or your symptoms suggest a deeper source, a duplex ultrasound — performed personally by Dr. Tadepalli. This single painless scan tells us whether your spider veins are an isolated cosmetic finding or the visible edge of reflux that should be addressed first. Either answer gives you a clear, honest starting point.
“Before I treat a single spider vein, I want to know why it’s there. Treating the surface while ignoring the source is how patients end up disappointed — and I’d rather do it right the first time.”— Dr. Satish Tadepalli, MD, MPH, DABVLM
How we treat them
Every treatment is office-based in Sparta, with no downtime. Walk in. Walk out.
- Visual sclerotherapy — the gold standard for surface spider veins. Using a very fine needle, Dr. Tadepalli injects a solution that irritates the vessel lining so it seals and gradually fades. Sessions run 30–45 minutes.
- Ultrasound-guided foam sclerotherapy — for feeder veins beneath the skin that visual treatment cannot reach.
- When significant reflux is found, closing the source vein first — with options such as radiofrequency ablation or Varithena® — makes the surface results cleaner and longer-lasting.
Treated vessels typically fade over several weeks. Purely cosmetic treatment is self-pay; if an underlying medical condition is found, its treatment is generally covered — we explain the difference plainly and verify insurance before treatment, so there is no surprise billing.
