Atherectomy is a minimally invasive technique for removing atherosclerosis from blood vessels within the body. It is an alternative to angioplasty for the treatment of peripheral artery disease , but the studies that exist are not adequate to determine whether it is superior to angioplasty. [ 1 ]
An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall. [1] [2]The material consists of mostly macrophage cells, [3] [4] or debris, containing lipids, calcium and a variable amount of fibrous connective tissue.
Occlusion of brain arteries leads to rapid ischemic death of neurons, both at the infarct core and ischemic penumbra. [10] [37] Similar to cardiomyocytes, neurons require constant perfusion for proper function. Any interruption of blood supply causes neurons to switch to anaerobic metabolism, [37] exhausting
This causes the hemorrhoidal tissue to shrink over time, alleviating symptoms such as pain, bleeding, and swelling. [ 1 ] [ 2 ] [ 4 ] Post-procedure, patients are monitored for a brief period to ensure stability before being discharged with instructions for managing any minor discomfort or symptoms that may occur during the recovery period.
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Carotid endarterectomy itself can cause strokes, so to be of benefit in preventing strokes over time, the risks for combined 30-day mortality and stroke risk following surgery should be < 3% for asymptomatic people and ≤ 6% for symptomatic people. [1] The carotid artery is the large vertical artery in red.
Vascular disease is a subgroup of cardiovascular disease. Disorders in this vast network of blood and lymph vessels can cause a range of health problems that can sometimes become severe, and fatal. [3] Coronary heart disease for example, is the leading cause of death for men and women in the United States. [5]
The vascular system strongly influences the condition of the heart. It is also vital in the rest of the body as the blood vessels are in charge of carrying nutrients and the discard of metabolic wastes. Therefore, blood vessel disorder can cause serious complications in the whole body. [citation needed]
