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.
Sneddon's syndrome is a progressive, noninflammatory arteriopathy leading to the characteristic skin condition and to cerebrovascular problems, including stroke, transient ischemic attack (TIA), severe but transient neurological symptoms thought to be caused by cerebral vasospasm, coronary disease and early-onset dementia.
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.
The risk allele at this locus results in increased mRNA expression of FCGR2A. In addition, a genetic association between IL12B and Takayasu arteritis was established (rs56167332, OR = 1.54, p = 2.18 × 10-8). A fifth genetic locus for the disease in an intergenic region on chromosome 21q22 downstream of PSMG1 was revealed (P=4.39X10-7). [9]
Endarterectomy is a surgical procedure to remove the atheromatous plaque material, or blockage, in the lining of an artery constricted by the buildup of deposits. It is carried out by separating the plaque from the arterial wall.
Without proper prevention or management, these diseases can progress into life-threatening complications of myocardial infarction, [7] gangrene, [8] ischemic stroke, [9] and in severe cases, terminate in brain death or cardiac arrest. [10] [11]
Arteriotomy (or arterotomy) is a medical term for an opening or cut of an artery wall. [1] It is a common step in many vascular surgical procedures and operations. The corresponding term for an incision into a vein is a venotomy.
