Endovascular aneurysm repair, is a type of endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair." The procedure involves the placement of an expandable stent graft within the aorta to treat aortic disease without operating directly on the aorta. The placement of the graft needs to leave the renal and iliac arteries open. In 2003, EVAR surpassed open aortic surgery as the most common technique for repair of AAA, and in 2010, EVAR accounted for 78% of all intact AAA repair in the United States.
Coronary Microvascular Disease
Coronary microvascular disease (sometimes called small artery disease or small vessel disease) is heart disease that affects the walls and inner lining of tiny coronary artery blood vessels that branch off from the larger coronary arteries. Coronary heart disease (CHD), also called coronary artery disease, involves plaque formation that can block blood flow. In coronary MVD, the heart's tiny coronary artery blood vessels do not have plaque, but damage to the inner walls of the blood vessels that can lead to spasms and decrease blood flow to the heart muscle.Women more frequently develop coronary microvascular disease and it occurs particularly in younger women; however, men and women who have coronary MVD often have diabetes, high blood pressure or a family history of cardiomyopathy.Diagnosing coronary MVD has been a challenge for doctors. Standard tests used to diagnose coronary heart disease are not designed to detect coronary MVD, so more research is needed to find the best diagnostic tests and treatments for the disease.
Peripheral artery diseases
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 oxygen-rich blood to the internal organs, arms, and legs become completely or partially blocked as a result of atherosclerosis. Atherosclerosis is a gradual process whereby hard cholesterol substances (plaques) are deposited in the walls of the arteries. This buildup of cholesterol plaques causes hardening of the artery walls and narrowing of the inner channel (lumen) of the artery.Arteries that are narrowed by advanced atherosclerosis can cause diseases in different organs. For example, advanced atherosclerosis of the coronary arteries (arteries that supply heart muscles) can lead to angina, coronary heart disease, and heart attacks. Advanced atherosclerosis of the carotid and cerebral arteries (arteries that supply blood to the brain) can lead to strokes and transient ischemic attacks (TIA). Advanced atherosclerosis in the lower extremities can lead to pain while walking or exercising (claudication), deficient wound healing, and/or leg ulcers.
Stroke is a disease that affects the arteries leading to and within the brain. It is the No. 5 cause of death and a leading cause of disability in the United States.A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures). When that happens, part of the brain cannot get the blood (and oxygen) it needs, so it and brain cells die. Brain AVM : Normally, arteries carry blood containing oxygen from the heart to the brain, and veins carry blood with less oxygen away from the brain and back to the heart. When an arteriovenous malformation (AVM) occurs, a tangle of blood vessels in the brain bypasses normal brain tissue and directly diverts blood from the arteries to the veins It may be possible to treat part or all of the AVM by placing a catheter (small tube) inside the blood vessels and blocking off the abnormal vessels with various materials, like glue or coils.
