Embolic stroke of undetermined source (ESUS) is an embolic stroke, a type of ischemic stroke, with an unknown origin, [1] defined as a non-lacunar brain infarct without proximal arterial stenosis or cardioembolic sources. [2] As such, it forms a subset of cryptogenic stroke, which is part of the TOAST-classification. [3]
The most common cause of arterial stenosis is atherosclerosis, however other pathologies such as fibromuscular dysplasia, dissection, trauma or external compression may occur. [2] Atherosclerotic plaque can rupture, resulting in a source of emboli. These emboli can cause TIAs or strokes in the areas of the brain supplied by the affected artery.
The surgical mortality of endarterectomy ranges from 1–2% to as much as 10%. Two large randomized clinical trials have demonstrated that carotid surgery done with a 30-day stroke and death risk of 3% or less will benefit asymptomatic people with ≥60% stenosis who are expected to live at least 5 years after surgery.
Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]
Aortic stenosis is most commonly caused by age-related progressive calcific aortic valve disease (CAVD) (>50% of cases), with a mean age of 65 to 70 years. CAVD is the build-up of calcium on the cusps of the valve, and this calcification causes hardening and stenosis of the valve. [22]
Stenosis (from Ancient Greek στενός (stenós) ' narrow ') is the abnormal narrowing of a blood vessel or other tubular organ or structure such as foramina and canals. It is also sometimes called a stricture (as in urethral stricture ).
The exact pathophysiology of Monckeberg's arteriosclerosis remains uncertain. However, it is thought that the condition arises from the fatty degeneration of smooth muscle cells within the arterial media, leading to the formation of a mass that undergoes hyaline degeneration and eventually calcification.
It can cause the affected limb to swell, and cause pain and an overlying skin rash. In the worst case, a deep vein thrombosis can extend, or a part of a clot can break off as an embolus and lodge in a pulmonary artery in the lungs, known as a pulmonary embolism .The decision to treat deep vein thrombosis depends on its size, a person's symptoms ...
