Vascular Diseases

Medical Definition:
Guide Notes:	GEN or unspecified vasc dis but CARDIOVASCULAR DISEASES; CEREBROVASCULAR DISORDERS & PERIPHERAL VASCULAR DISEASES are also available; inflamm vasc dis = VASCULITIS; vasc compression syndrome: see note on PERIPHERAL VASCULAR DISEASES

Vascular Diseases Categories.

	Aneurysm - A sac formed by the dilatation of the wall of an artery, a vein, or the heart.
	Angiodysplasia - Degenerative, acquired lesions consisting of distorted, dilated, thin-walled vessels lined by vascular endothelium. This pathological state is seen especially in the gastrointestinal tract and is frequently a cause of upper and lower gastrointestinal hemorrhage in the elderly.
	Angiomatosis
	Angioneurotic Edema - Recurring attacks of transient edema suddenly appearing in areas of the skin or mucous membranes and occasionally of the viscera, often associated with dermatographism, urticaria, erythema, and purpura.
	Aortic Diseases
	Arterial Occlusive Diseases - Diseases in which arterial vessels are partially or completely obstructed or in which the blood flow through the vessels is impeded.
	Arteritis - Inflammation of an artery.
	Capillary Leak Syndrome - A rare and sometimes fatal disease characterized by recurring attacks of leakage of intravascular fluids into the extravascular space. This syndrome is observed in patients who demonstrate a state of generalized leaky capillaries following shock syndromes, low-flow states, ischemia-reperfusion injuries, toxemias, or poisoning. It can lead to generalized edema and MULTIPLE ORGAN FAILURE. (Zikria, et al. (eds.), Reperfusion Injuries and Clinical Capillary Leak Syndrome, pp. 470-72, 1994)
	Diabetic Angiopathies - VASCULAR DISEASES that are associated with DIABETES MELLITUS.
	Embolism and Thrombosis - A collective term for diseases characterized by the formation, development, or presence of a thrombus (THROMBOSIS) and the blocking of a vessel by the thrombus brought to its site by the blood current (EMBOLISM). (From Dorland, 28th ed)
	Erythromelalgia - Disease marked by paroxysmal, bilateral vasodilatation, particularly of the extremities, with burning pain, and increased skin temperature and redness.
	Hypertension - Persistently high arterial blood pressure. Currently accepted threshold levels are 140 mm Hg systolic and 90 mm Hg diastolic pressure.
	Hypotension - Abnormally low blood pressure seen in shock but not necessarily indicative of it. (Dorland, 28th ed)
	Ischemia - Blood deficiency in an organ or tissue caused by a constriction or obstruction of its blood vessels.
	Peripheral Vascular Diseases - General or unspecified diseases of the blood vessels outside the heart. It is for diseases of the peripheral as opposed to the cardiac circulation.
	Phlebitis - Inflammation of a vein.
	Raynaud Disease - An idiopathic vascular disorder characterized by bilateral Raynaud phenomenon, the abrupt onset of digital paleness or CYANOSIS in response to cold exposure or STRESS.
	Superior Vena Cava Syndrome - Obstruction of the superior vena cava caused by neoplasm, thrombosis, aneurysm, or external compression and causing suffusion and/or cyanosis of the face, neck, and upper arms.
	Telangiectasis - Permanent dilation of preexisting blood vessels (capillaries, arterioles, venules) creating small focal red lesions, most commonly in the skin or mucous membranes.
	Varicose Veins - Enlarged and tortuous VEINS.
	Vascular Fistula - An abnormal passage between two or more arteries, or between an artery and a vein.
	Vascular Hemostatic Disorders - Alterations in the mechanical integrity or structure of the blood vessels leading to bleeding disorders.
	Vasculitis - Inflammation of a blood vessel.
	Venous Insufficiency - Inadequacy of the venous valves and impairment of venous return (venous stasis) usually from the legs, often with edema and sometimes with stasis ulcers at the ankle.
