Spider veins can be the ‘tip of the iceberg’ and represent a bigger problem, that is not visible to the naked eye. For example, as seen in the first image, spider veins can arise from blue ‘feeder’ veins, which must be treated for best results.
Spider veins can also stem from an underlying problem such as venous reflux in larger veins, such as the great saphenous vein. As demonstrated in the second picture, spider veins in the inner knee, inner ankle and inner thighs can originate from this vein. This can only be determined by ultrasound examination. It is important to have your vein evaluated by a trained specialist. Effective treatment depends on an accurate and thorough diagnosis.
