A. Blood would leak backwards through the damaged valves due to gravity, causing lower leg swelling.
Explanation:
The passage of blood is always in a single direction in the vein due to the presence of valves in the veins.
Any kind of vein injury or vein rupture, causes the valves in the veins to not function in an appropriate manner. The injury might result in inappropriate opening and closing of these valves. The inappropriate functioning of the valves causes the blood to flow backwards. This will eventually lead to blood pooling and putting more pressure on the lower leg veins. hence, there would be swelling in the lower legs.
