A pregnant patient comes into a clinic and asks about a small dark bulge that is becoming more apparent on her leg. What is it and what caused it?
What will be an ideal response?
The patient is getting a varicose vein. Due to the growing fetus putting downward pressure on the vessels of the groin and restricting the return of blood to the heart, the valves in the peripheral veins begin to fail. This causes blood pooling, which enlarges these veins and puts additional strain on other peripheral vein valves down the line.
