Understanding Spider Veins
Spider veins, known medically as telangiectasias, are small dilated blood vessels that appear close to the skin’s surface. They typically measure less than one millimeter in diameter and form web-like clusters of red, blue, or purple lines—most commonly on the legs, ankles, and face. While many people consider spider veins a purely cosmetic nuisance, they can sometimes point to underlying venous insufficiency that warrants further evaluation.
These tiny vessels develop when the one-way valves inside superficial veins weaken, allowing blood to pool and creating visible networks beneath the skin. An estimated 50 to 55 percent of women and 40 to 45 percent of men experience some form of venous insufficiency during their lifetime, with spider veins being among the earliest and most visible manifestations.
At Vascular Surgical Associates, our board-certified vascular surgeons and dedicated Vein Center team have been diagnosing and treating spider veins across metro Atlanta since 1986. We take a thorough, patient-centered approach—first ruling out deeper venous problems with advanced diagnostic imaging in our ICAVL-accredited vascular lab, then tailoring a treatment plan that addresses both the appearance and the underlying cause of your spider veins.
Signs & Symptoms
Spider veins are often identified by their distinctive appearance, but they may also produce subtle physical symptoms that patients sometimes overlook. Recognizing these signs early can help determine whether a deeper venous issue may be contributing to the problem.
Visible Vein Networks
Small red, blue, or purple veins visible near the skin’s surface, often forming branching, web-like patterns on the thighs, calves, or ankles.
Mild Aching or Burning
A dull, aching sensation or mild burning feeling in the areas where spider veins are concentrated, particularly after prolonged standing or sitting.
Itching Around Veins
Persistent itching or irritation in the skin directly surrounding the affected veins, sometimes mistaken for a dermatological issue rather than a vascular one.
Heaviness in the Legs
A sensation of weight or fatigue in the legs that worsens as the day progresses, often improving with leg elevation or walking.
Cosmetic Concerns
Noticeable clusters of fine veins that cause self-consciousness, especially during warmer months when legs are more visible. Appearance may gradually worsen over time.
Risk Factors
Several factors can increase the likelihood of developing spider veins. While some are unavoidable, understanding your personal risk profile can help you take preventive steps and seek timely evaluation when needed.
Heredity & Family History
A strong genetic component means that individuals whose parents or siblings have spider veins are significantly more likely to develop them.
Prolonged Standing
Occupations that require long periods of standing or sitting restrict calf-muscle pump activity, increasing venous pressure in the lower extremities.
Pregnancy
Increased blood volume, hormonal shifts, and added pressure on pelvic veins during pregnancy make spider veins more common, especially in the second and third trimesters.
Hormonal Changes
Fluctuations in estrogen and progesterone—from oral contraceptives, hormone replacement therapy, or menopause—can weaken vein walls and promote spider vein formation.
Sun Exposure
Chronic sun exposure damages the collagen beneath the skin and can cause spider veins to develop on the face, particularly on the nose and cheeks.
Obesity
Excess body weight places additional pressure on leg veins, impairing venous return and increasing the risk of both spider veins and more serious venous conditions.
Age
As you age, the valves inside your veins naturally lose strength and elasticity. The cumulative wear on vein walls makes spider veins increasingly common after age 40.
How Spider Veins Are Diagnosed
Diagnosing spider veins typically begins with a careful visual examination by one of our vascular specialists. Because visible spider veins can sometimes be the surface sign of a deeper venous problem, our team goes beyond appearance alone to ensure an accurate and complete evaluation.
Visual Examination – Your physician will closely inspect the affected areas while you are standing to assess the pattern, distribution, and extent of visible spider veins. The color and location of the veins can provide important clues about the source vessels feeding them.
Duplex Ultrasound – Using our ICAVL-accredited vascular lab, we perform a duplex ultrasound to evaluate blood flow in the deeper and superficial venous systems. This painless, non-invasive imaging test helps rule out underlying venous insufficiency or reflux that may be contributing to spider vein formation. Identifying hidden reflux is essential to achieving lasting treatment results.
Treatment Options
At Vascular Surgical Associates, our Vein Center provides a range of evidence-based treatments tailored to the severity of your spider veins and your personal goals. We develop individualized treatment plans that address both the cosmetic appearance and any underlying venous disease.
Conservative Care
For mild cases, graduated compression stockings can improve circulation and relieve symptoms. Combined with regular exercise, periodic leg elevation, and weight management, conservative measures may slow the progression of spider veins and provide symptom relief.
Sclerotherapy
The gold-standard treatment for spider veins, sclerotherapy involves injecting a specialized solution directly into the affected veins, causing them to collapse and gradually fade from view. Sessions are performed in our office with no anesthesia needed, and most patients return to normal activities the same day.
Laser Therapy
External laser therapy directs focused light energy through the skin to target and seal off spider veins without needles or incisions. This approach is particularly effective for very fine veins or those on the face where injection-based methods may not be ideal.
Frequently Asked Questions About Spider Veins
Spider veins themselves are not considered dangerous and do not typically lead to serious health complications. However, they can occasionally indicate underlying venous insufficiency in the deeper veins. That is why we recommend a thorough evaluation—including duplex ultrasound—to ensure there is no hidden reflux or venous disease that could progress if left untreated.
The number of sessions depends on the extent and distribution of your spider veins. Many patients see significant improvement after two to four sessions, with each session spaced several weeks apart. During your initial consultation, your Vein Center specialist will examine your veins and provide a personalized treatment timeline.
while the medically necessary portion of your treatment if an underlying condition is identified may qualify for insurance coverage, insurance companies typically do not provide coverage for sclerotherapy.
Treated spider veins do not reopen, but new spider veins can develop over time, particularly if underlying risk factors—such as genetics, hormonal changes, or prolonged standing—remain present. Addressing any deeper venous reflux before treating spider veins reduces the chance of recurrence. Maintaining a healthy weight, staying active, and wearing compression stockings when recommended also help keep new spider veins at bay.
