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. |

|
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. |
