• Risk factors associated with vascular health problems
• Hypertension
• Peripheral Vascular Disease
• Deep vein thrombosis (DVT)
• Varicose Veins
• Arteriospastic Disease (Raynaud's Disease)
• Thromboangiitis Obliterans (Buerger's Disease)
• Aneurysms

Aneurysm

a dilatation or an outpouching of a wall of an artery or vein that can occur anywhere in body

Chronic venous insufficiency

chronic failure of venous valves to function, resulting in interference with venous blood return to heart and production of generalized systemic edema

Embolus

A foreign object such as a piece of a thrombus floating in bloodstream until such time as it becomes trapped in a vessel

Ischemia https://www.youtube.com/watch?v=PCdLBXb7JO

a deficiency in supply of oxygenated blood caused by a circulatory obstruction; client experiences considerable pain in affected part

Peripheral vascular resistance (PVR)

sum of all resistances within vascular system

Pheochromocytoma

https://www.youtube.com/watch?v=JfguwfFqt- Pheochromocytoma is a rare tumor that usually starts in the cells of one of your adrenal glands and is responsible for about 0.1-2.0% of cases of hypertension; tumor cells release catecholamines that cause episodic and sustained heart palpitations, sweating, headaches, fainting, and hypertensive emergencies

Secondary hypertension

An elevated blood pressure associated with pulmonary, circulatory, endocrine, and renal diseases such as hyperaldosteronism, pheochromocytoma, Cushing's disease, diabetes mellitus, coarctation of aorta, and hyperthyroidism

Systolic pressure of blood against arterial walls when ventricles of heart are contracted Diastolic pressure of blood against arterial walls when ventricles of heart are at rest

Varicose veins https://www.youtube.com/watch?v=9Wf8bLXVwFI

dilated, tortuous leg veins

Primary varicose veins

dilated superficial veins; seldom involves communicating veins; if valvular breakdown occurs, it is caused by hereditary factors

Thrombophlebitis https://www.youtube.com/watch?v=1N_bxIzFGOI

inflammation of a vein with clot formation within that vein

White coat phenomenon

hypertension that occurs in a normotensive client when a health care professional measures blood pressure; differentiation between white coat hypertension and secondary hypertension is essential for effective therapy to begin
