Leg telangiectasias, often called spider veins or broken capillaries, are small dilated superficial vessels on the legs, appearing red, blue or purple. They are not only a cosmetic concern: in some cases, they may be associated with microcirculatory fragility or superficial venous insufficiency.
They correspond to dilated small skin vessels on the legs, more common in women and favoured by genetic and hormonal factors, pregnancy, standing work and overweight. Typical signs include visible capillaries on thighs, calves or ankles, sometimes with heaviness, burning or evening discomfort. A specialist vascular assessment is essential to distinguish between a purely superficial aesthetic issue and signs of deeper venous disease.
