Vein Treatments in Chicago Spider veins usually take on one of three basic patterns. They may appear in a true spider shape with a group of veins radiating outward from a dark central point.
They may be arborizing and will resemble tiny branch-like shapes. Or they may be linear and appear as thin separate lines. Linear spider veins are commonly seen on the inner knee, whereas the arborizing pattern often appears on the outer thigh in a sunburst or cartwheel distribution.
