How a varicose vein forms in a leg. Figure A shows a normal vein with a working valve and normal blood flow. Figure B shows a varicose vein with a deformed valve, abnormal blood flow, and thin, stretched walls. The middle image shows where varicose veins might appear in a leg.
Comparison of healthy and varicose veins

Varicose veins, also known as varicoses, are a medical condition in which superficial veins become enlarged and twisted.
