Final answer:
Leriche's Syndrome, also known as Aortoiliac Occlusive Disease, is the blockage or narrowing of the common iliac artery (CIA) leading to restricted blood flow to the lower extremities. It can cause symptoms like leg pain and impotence, and if left untreated, can lead to severe complications.
Step-by-step explanation:
Leriche's Syndrome, also known as Aortoiliac Occlusive Disease, refers to the blockage or narrowing of the common iliac artery (CIA), which is the major artery that supplies blood to the lower part of the body. This condition occurs when atherosclerosis, or the buildup of plaque, restricts blood flow to the lower extremities.
The blockage or narrowing of the CIA can cause symptoms such as claudication (pain in the legs during physical activity), impotence in males, and weak or absent pulses in the legs. If left untreated, it can lead to more severe complications, including critical limb ischemia and gangrene.
