What is critical limb ischemia?
Critical limb ischemia is a potentially serious condition that occurs when the leg or arm does not receive a sufficient supply of new blood. Symptoms can be responsible for accumulation of cholesterol, blood clots in the main arteries and other problems with circulation. Critical limb ischemia is usually characterized by pain, weakness and swelling in the affected part of the body, which often deteriorates during sleep or prolonged seating or standing period. If the blood supply is seriously limited, the skin and background tissue can begin to erode and create dark lesions. Treatment measures are aimed at repairing basic factors and may include medicines, major lifestyle changes and surgery.
In most cases, critical ischemia of limbs is complications of peripheral arteries (PAD). Pad indicates narrowing or blocking in a vital artery in the leg caused by high levels of cholesterol and triglycerides in the blood. Cholesterol solidifies and connects to the walls of the artery over time, which limits the amount of bloodE, which can achieve a limb and at the same time significantly increase blood pressure. For critical limb ischemia in a small number of patients, critical limb ischemia is unrelated by a blood clot, congenital defect of blood vessels or autoimmune disorder.
Pad and the resulting critical limb ischemia tend to evolve gradually. The person may first notice minor pain and swelling in his leg in the morning that will be resolved quickly. Over time, however, pain and weakness deteriorate and cause problems during the day. Symptoms may be bad enough to disrupt sleep and do everyday activities such as walking and almost unbearable management. Without treatment, reduced blood flow to the skin can cause tissue death and ulcers.
Most people who experience critical ischemia of limbs already know that Pad are at risk of previous visits. It is important to see a doctor when the problems with the arm or foot of BecojA chronic, so the diagnosis of the pad can be appropriately confirmed and treated. The doctor may perform physical, ask about symptoms and analyze blood samples to measure the severity of the problem.
When the limb ischemia is discovered soon, it often responds to medicines and lifestyle changes. Patients are usually instructed to maintain low -fat and low -floor food, regular exercise and delayed tobacco and alcohol. Blood pressure drugs and cholesterol drugs are often prescribed to try to reverse the problem. Surgery is considered to be the final option if the symptoms do not improve.
If operation is required, the specialist may decide to put hard stent into a damaged artery or completely bypass the area. The procedure of angioplasty involves placing the balloon in the blood vessel and inflating to distribute the walls. The artery is placed stent to open and prevent cholesterol from further building. Bypass requires cutting off the blodian from to artery and inserts either artificial or donor KR in its placeEat the blood vessel. Most patients may recover from surgery if they follow the instructions of their doctors to decide on intelligent lifestyle.
