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 ]
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 ...
In the legs, bypass grafting is used to treat peripheral vascular disease, acute limb ischemia, aneurysms and trauma.While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow.
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.
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.
Macroangiopathy may cause other complications, such as ischemic heart disease, stroke and peripheral vascular disease which contributes to the diabetic foot ulcers and the risk of amputation. In microangiopathy, the walls of the smaller blood vessels become so thick and weak that they bleed , leak protein , and slow the flow of blood through ...
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.
Often Segmental Arterial Mediolysis is diagnosed after clinical presentation with symptoms as above followed by CT angiogram or MRI demonstrating aneurysm(s). [4] The gold standard method for confirming the diagnosis is surgical resection of the affected area of blood vessel followed by histologic investigation under a microscope. [ 3 ]
