Subclavian steal syndrome (SSS), also called subclavian steal steno-occlusive disease, is a medical condition characterized by retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery. This reversal occurs due to proximal stenosis (narrowing) or occlusion of the subclavian artery.
Steal syndrome may refer to: Cardiac steal syndrome; Subclavian steal syndrome, often associated with fainting, and typically due to atherosclerosis; Vascular access steal syndrome, a problem related to a surgically created vascular access (fistula) for hemodialysis
Student syndrome; Sturge–Weber syndrome; Subclavian steal syndrome; Sudden death syndrome; Sudden infant death syndrome; Sudden wealth syndrome; Sugarman syndrome; Sulfonamide hypersensitivity syndrome; Summer penile syndrome; Sundowning; Superior mesenteric artery syndrome; Superior orbital fissure syndrome; Superior vena cava syndrome
Vascular access steal syndrome is a syndrome caused by ischemia (not enough blood flow) resulting from a vascular access device (such as an arteriovenous fistula or synthetic vascular graft–AV fistula) that was installed to provide access for the inflow and outflow of blood during hemodialysis.
VBI may also result from altered blood flow as seen in subclavian steal syndrome. VBI is described as a cause of symptoms that occur with changes to head position. Rotational vertebral artery syndrome (sometimes referred to as Bow Hunter's Syndrome) results from vertebral artery compression on rotating the neck. [7]
Coronary steal is also the mechanism in most drug-based cardiac stress tests; When a patient is incapable of doing physical activity they are given a vasodilator that produces a "cardiac steal syndrome" as a diagnostic procedure. The test result is positive if the patient's symptoms reappear or if ECG alterations are seen. [citation needed]
Takayasu's arteritis (TA), also known as aortic arch syndrome, nonspecific aortoarteritis, and pulseless disease, [2] is a form of large vessel granulomatous vasculitis [3] with massive intimal fibrosis and vascular narrowing, most commonly affecting young or middle-aged women of Asian descent, though anyone can be affected.
Moyamoya disease is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by constriction and blood clots (). [2]A collateral circulation develops around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to bleeding, aneurysm and thrombosis.
