Spider veins (telangiectasias) are tiny superficial blood vessels often found on the calves, thighs, and ankles. These veins are generally not considered a health problem, but symptoms such as itching, burning, and achiness can occur and will worsen if left untreated. Causes of spider veins include heredity, pregnancy, prolonged standing or sitting, trauma or pressure, and hormonal changes.
Sclerotherapy is the gold standard in treating cosmetic spider veins. Using a tiny needle, a solution is injected into hte problems veins, causing the vein walls to swell, collapse and fade away within a few weeks. For best results, three to five treatments per affected area may be required. Patients need to wear compression stockings after each treatment but can resume normal activities almost immediately.
