Peritonitis is defined as inflammation of the peritoneum. The inflammatory response involves vasodilation, exudation of protein-rich fluid, cellular infiltration, pain and, chronically, formation of fibrous adhesion. The disease can be classified into primary and secondary cases.
In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor canal (also known as Hunter's canal) and is a continuation of the popliteal vein. It ends at the inferior margin of the inguinal ligament, where it becomes the external iliac vein.
The Great Saphenous Vein (GSV) is the main truncal vein of the lower leg and, as such, drains blood from the inner part of the foot, the skin and fat of the front and inner aspect of the lower leg, and the skin and fat of the inner part of the thigh.
