Endarterectomy
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. It was first performed on a subsartorial artery in 1946 by a Portuguese surgeon, João Cid dos Santos, at the University of Lisbon. In 1951, E. J. Wylie, an American, performed it on the abdominal aorta. The first successful reconstruction of the carotid artery was performed by Carrea, Molins, and Murphy in Argentina, later in the same year. An endarterectomy of the carotid artery in the neck is recommended to reduce the risk of stroke when the carotid artery is severely narrowed, particularly after a stroke to reduce the risk of additional strokes. Coronary endarterectomy involves removing atheroma from the wall of blocked blood vessels (coronary) supplying the heart muscle. The concept was first introduced by Bailey in the 1950s prior to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carotid Endarterectomy
Carotid endarterectomy is a surgical procedure used to reduce the risk of stroke from carotid artery stenosis (narrowing the internal carotid artery). In endarterectomy, the surgeon opens the artery and removes the plaque. The plaque forms and thickens the inner layer of the artery, or ''intima'', hence the name of the procedure which simply means removal of part of the internal layers of the artery. An alternative procedure is carotid stenting, which can also reduce the risk of stroke for some patients. Medical uses 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 symptoms (asymptomatic) - and the risk-reduction from endarterectomy is greater for symptomatic than asymptomatic patients. Carotid endartectomy itself can cause strokes, so to be of benefit in preventing strokes over time, the risks for combined 30-day mo ...

Cerebrovascular Accident
A stroke is a medical condition in which poor blood flow to the brain causes cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and loss of bladder control. The main risk factor for stroke is high blood pressure. Other risk factors include high blood cholesterol, tobacco smoking, obesity, diabetes mellitus, a previous TIA, end-stag ...

Pulmonary Thromboendarterectomy
In thoracic surgery, a pulmonary thromboendarterectomy (PTE), also referred to as pulmonary endarterectomy (PEA), is an operation that removes organized clotted blood (thrombus) from the pulmonary arteries, which supply blood to the lungs. Indication Surgery is indicated in patients with pulmonary artery emboli that are surgically accessible. Thrombi are usually the cause of recurrent/chronic pulmonary emboli and therefore of chronic thromboembolic pulmonary hypertension (CTEPH). PTE is the only definitive treatment option available for CTEPH.Chronic thromboembolic pulmonary hypertension. Fedullo P, Kerr KM, Kim NH, Auger WR Am J Respir Crit Care Med. 2011;183(12):1605. Due to the nature of the procedure, patients with significant hemodynamic or ventilation complications or impairments may be unable to undergo PTE. Description of the surgery A PTE has significant risk; mortality for the operation is typically 5%, but less in centers with high volume and experience. Individuals ...

Subsartorial Artery
The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg. The femoral artery gives off the deep femoral artery or profunda femoris artery and descends along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor canal, and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh. Structure The femoral artery enters the thigh from behind the inguinal ligament as the continuation of the external iliac artery. Here, it lies midway between the anterior superior iliac spine and the symphysis pubis (Mid-inguinal point). Segments In clinical parlance, the femoral artery has the following segments: *The common femoral artery (CFA) is the segment of the femoral artery between the inferior margin of the inguinal ligament and the branching point of the deep femoral artery/profunda femoris artery.

Leeds
Leeds () is a city and the administrative centre of the City of Leeds district in West Yorkshire, England. It is built around the River Aire and is in the eastern foothills of the Pennines. It is also the third-largest settlement (by population) in England, after London and Birmingham. The city was a small manorial borough in the 13th century and a market town in the 16th century. It expanded by becoming a major production centre, including of carbonated water where it was invented in the 1760s, and trading centre (mainly with wool) for the 17th and 18th centuries. It was a major mill town during the Industrial Revolution. It was also known for its flax industry, iron foundries, engineering and printing, as well as shopping, with several surviving Victorian era arcades, such as Kirkgate Market. City status was awarded in 1893, a populous urban centre formed in the following century which absorbed surrounding villages and overtook the nearby York population. It is locate ...

Atherectomy
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. It has also been used to treat coronary artery disease, albeit without evidence of superiority to angioplasty. Uses Atherectomy is used to treat narrowing in arteries caused by peripheral artery disease and coronary artery disease. Controversy The use of atherectomy instead of or in addition to angioplasty remains an area of controversy, as atherectomy typically involves the use of more costly disposable devices, and clear evidence to justify its use is lacking. Atherectomy has high physician reimbursement relative to angioplasty alone. Technique Unlike angioplasty and stents, which push plaque into the vessel wall, atherectomy cuts plaque from the wall of the artery. While atherectomy is usu ...

Pulmonary Artery
A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. The largest pulmonary artery is the ''main pulmonary artery'' or ''pulmonary trunk'' from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli. Structure The pulmonary arteries are blood vessels that carry systemic venous blood from the right ventricle of the heart to the microcirculation of the lungs. Unlike in other organs where arteries supply oxygenated blood, the blood carried by the pulmonary arteries is deoxygenated, as it is venous blood returning to the heart. The main pulmonary arteries emerge from the right side of the heart, and then split into smaller arteries that progressively divide and become arterioles, eventually narrowing into the capillary microcirculation of the lungs where gas exchange occurs. Pulmonary trunk In order of blood flow, the pulmonary art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Anastomosis
A surgical anastomosis is a surgical technique used to make a new connection between two body structures that carry fluid, such as blood vessels or bowel. For example, an arterial anastomosis is used in vascular bypass and a colonic anastomosis is used to restore colonic continuity after the resection of colon cancer. A surgical anastomosis can be created using suture sewn by hand, mechanical staplers and biological glues, depending on the circumstances. While an anastomosis may be end-to-end, equally it could be performed side-to-side or end-to-side depending on the circumstances of the required reconstruction or bypass. The term reanastomosis is also used to describe a surgical reconnection usually reversing a prior surgery to disconnect an anatomical anastomosis, e.g. tubal reversal after tubal ligation. __TOC__ Medical uses * Blood vessels: Arteries and veins. Most vascular procedures, including all vascular bypass operations (e.g. coronary artery bypass), aneurysmectomy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
