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 ]
The signs and symptoms of peripheral artery disease are based on the affected body part. About 66% of patients affected by PAD either do not have symptoms or have atypical symptoms. [19] The most common presenting symptom is intermittent claudication (IC), which typically refers to lower extremity skeletal muscle pain that occurs during ...
Vascular surgeons are experts in the diagnosis, medical management, endovascular and open surgical treatment of PAD. [20] A vascular surgeon may diagnose PAD using a combination of history, physical exam and medical imaging. Medical imaging may include ankle-brachial index, doppler ultrasonography and computed tomography angiography, among others.
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.
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]
Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries.This is a chronic inflammatory disease involving many different cell types and is driven by elevated levels of cholesterol in the blood. [9]
Atherectomy is a valuable adjunctive therapy for patients with coronary artery disease, particularly those with severely calcified lesions where traditional balloon angioplasty and stenting may be insufficient. Its success depends on the selection of appropriate devices and the operator’s expertise in managing the technical nuances to ...
Carotid endarterectomy is used to reduce the risk of strokes caused by carotid artery stenosis over time. Carotid stenosis can either have symptoms (i.e., be symptomatic), or be found by a doctor in the absence of symptoms (asymptomatic) - and the risk-reduction from endarterectomy is greater for symptomatic than asymptomatic patients.
