Vascular disease includes any condition that affects the circulatory system. As the heart beats, it pumps blood through a system of blood vessels called the circulatory system. The vessels are elastic tubes that carry blood to every part of the body. Arteries carry blood away from the heart while veins return it.
Vascular disease ranges from diseases of your arteries, veins, and lymph vessels to blood disorders that affect circulation. The following are conditions that fall under the category of vascular disease.
Peripheral Artery Disease
Like the blood vessels of the heart (coronary arteries), your
peripheral arteries (blood vessels outside your heart) also may develop atherosclerosis, the build-up of fat and cholesterol deposits, called plaque, on the inside walls. Over time, the build-up narrows the artery. Eventually the narrowed artery causes less blood to flow and a condition called "ischemia" can occur. Ischemia is inadequate blood flow to the body's tissue.
A blockage in the carotid arteries (the arteries supplying the brain) can lead to a transient ischemic attack (TIA) or stroke.
A blockage in the legs can lead to leg pain or cramps with activity (a condition called claudication), changes in skin color, sores or ulcers, and feeling tired in the legs. Total loss of circulation can lead to gangrene and loss of a limb.
A blockage in the renal arteries (arteries supplying the kidneys) can cause renal artery disease (stenosis). The symptoms include uncontrolled hypertension (high blood pressure), heart failure, and abnormal kidney function.
Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus. Risk factors for blood clots include high blood pressure and cholesterol, diabetes, smoking, and family history. Symptoms of a blood clot depend on the location of the clot. Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
Inflammation of the inner lining of the colon is referred to as colitis. Symptoms of the inflammation of the colon lining include diarrhea, pain, and blood in the stool. There are several causes of colitis including infection, ischemia of the colon, inflammatory bowel disease (Crohn's disease, Ulcerative colitis, or microscopic colitis). Treatment depends on the cause of the colitis.
Peripheral vascular disease (PVD) refers to diseases of the blood vessels (arteries and veins) located outside the heart and brain. While there are many causes of peripheral vascular disease, doctors commonly use the term peripheral vascular disease to refer to peripheral artery disease (peripheral arterial disease, PAD), a condition that develops when the arteries that supply blood to the internal organs, arms, and legs become completely or partially blocked as a result of atherosclerosis. Peripheral artery disease symptoms include: intermittent claudication, rest pain, numbness in the extremities, and more. Treatment for peripheral artery disease include: lifestyle measures, medication, angioplasty, and surgery.
Connective tissue disease is when the body's connective tissues come under attack, possibly becoming injured by inflammation. Inherited connective tissue diseases include Marfan syndrome and Ehlers-Danlos syndrome. Systemic lupus erythematosus, rheumatoid arthritis, scleroderma, polymositis, and dermatomyositis are examples of connective tissue diseases that have no known cause.
Arteriovenous malformation (AVM) is a congenital disorder of blood vessels in the brain, brainstem, or spinal cord that is characterized by a complex, tangled web of abnormal arteries and veins connected by one or more fistulas (abnormal communications). Symptoms of arteriovenous malformations include seizures and headaches. Treatment of arteriovenous malformations include medication or surgery.
Arteriovenous malformations (AVMs) are defects of the circulatory system that
are generally believed to arise during embryonic or fetal development or soon
after birth. They are comprised of snarled tangles of arteries and veins.
Arteries carry oxygen-rich blood away from the heart to the body's cells; veins
return oxygen-depleted blood to the lungs and heart. The
presence of an AVM disrupts this vital cyclical process. Although AVMs can develop in many
different sites, those located in the brain or spinal cord-the two parts of the
central nervous system-can have especially widespread effects on the body.
AVMs of the brain or spinal cord (neurological AVMs) are believed to affect
approximately 300,000 Americans. They occur in males and females of all racial
or ethnic backgrounds at roughly equal rates.
