The circulatory system involving blood vessels and valves is quite an intricate networking system. Blood flow is maintained in separate channels controlled by valves. The vessels distant from the heart are known as peripheral arteries (and veins). Due to fatty deposits, the blood vessels narrow, and therefore their blood-carrying capacity reduces. This leads to reduced blood supply to the legs. The blood carries essential nutrients, and when the legs do not receive it, their function is affected. Read on to know more about this condition.
Peripheral artery disease: As noted above, peripheral artery disease or peripheral vascular disease is when the peripheral organs do not receive adequate blood supply. This could be either due to vascular structural abnormalities or more commonly due to atherosclerosis.
Symptoms: PVD or PAD is a chronic disease, and there are no immediate symptoms. The onset happens over a period of time, and symptoms include:
Complications: PAD reduces blood supply to the distant organs. Therefore, the limbs can have ischemia and also undergo death. It is common for sores to not heal due to the poor blood supply. When this condition continues for a prolonged period, then portions of the extremities could become dead due to lack of blood supply. This could also affect the brain and heart, causing stroke and heart attacks.
Treatment: Peripheral artery disease can be treated by the following measures:
