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 ]
Coronary endarterectomy involves removing atheroma from the wall of blocked blood vessels (coronary) supplying the heart muscle. The concept was first introduced by Bailey [2] in the 1950s prior to the advent of coronary artery bypass surgery to help patients with angina and coronary artery disease. It is still used today when coronary artery ...
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-reduction from intervention for carotid stenosis (stenting or endarterectomy) is greatest when the indication for intervention is symptoms (i.e., the patient is symptomatic) - typically stroke or TIA. [6] A new generation of double-layer stents is currently being developed to reduce the risk of stroke during or after the procedure.
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 thoracic surgery, a pulmonary thromboendarterectomy (PTE), also referred to as pulmonary endarterectomy (PEA), [1] is an operation that removes organized clotted blood from the pulmonary arteries, which supply blood to the lungs.
In some cases where the blockage is not as severe or limb threatening, alternative procedures that may take place are percutaneous transluminal angioplasty or endarterectomy. These procedures are used when possible as they are considered to be minimally invasive, in turn reducing recovery time and possible complications post-surgery.
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.
