Microangiopathy (also known as microvascular disease, small vessel disease (SVD) or microvascular dysfunction) is a disease of the microvessels, small blood vessels in the microcirculation. [1] It can be contrasted to macroangiopathies such as atherosclerosis , where large and medium-sized arteries (e.g., aorta , carotid and coronary arteries ...
The microvascular dysfunctions refer to the abnormalities in the very small blood vessels of the heart. The narrowing of these vessels may lead to lack of oxygen in specific areas of the cardiac muscle causing chest pain. Several studies have shown that patients living with microvascular angina may have an enhanced pain perception, and usually ...
Cutaneous small-vessel vasculitis (CSVV) is inflammation of small blood vessels, usually accompanied by small lumps beneath the skin. [1]: 831 [2] The condition is also known as hypersensitivity vasculitis, cutaneous leukocytoclastic vasculitis, hypersensitivity angiitis, cutaneous leukocytoclastic angiitis, cutaneous necrotizing vasculitis and cutaneous necrotizing venulitis, [3]
Buerger's disease – inflammation and swelling in small blood vessels, causing the vessels to narrow or become blocked by blood clots. [18] Raynaud syndrome – a peripheral vascular disorder that causes constriction of the peripheral blood vessels in the fingers and toes when a person is cold or experiencing stress. [19]
Angiopathy is the generic term for a disease of the blood vessels (arteries, veins, and capillaries). [1] This also refers to the condition of damage or rupture of small blood vessels. The best known and most prevalent angiopathy is diabetic angiopathy, a common complication of chronic diabetes.
Takayasu arteritis (TA) is a large-vessel, idiopathic, granulomatous arteritis that primarily affects the aorta, significant branches of it, and (less frequently) the pulmonary arteries. [6] The disease's symptoms can range from catastrophic neurological impairment to an asymptomatic condition brought on by impalpable pulses or bruits. [7]
Disseminated intravascular coagulation (DIC) is a condition in which blood clots form throughout the body, blocking small blood vessels. [1] Symptoms may include chest pain, shortness of breath, leg pain, problems speaking, or problems moving parts of the body. [1] As clotting factors and platelets are used up, bleeding may occur. [1]
Variable vessel vasculitis (VVV) is a kind of vasculitis that may impact vessels of all sizes (small, medium, and large) and any type (arteries, veins, and capillaries), with no particular type of vessel being predominantly affected. [33] This category includes Behcet's disease (BD) and Cogan's syndrome (CS). [8]
