Arteriectomy is a surgical procedure in which an artery is partially or completely removed due to disease or damage, such as blockage or aneurysm. It involves cutting away the affected section of the artery and reconnecting the healthy portions to restore proper blood flow. This operation is typically performed to treat conditions like arteriosclerosis, where plaque buildup narrows or hardens the arteries.
Arteries
Arteries are blood vessels that carry oxygenated blood away from the heart to various parts of the body. They are essential for delivering nutrients, oxygen, and hormones to cells and tissues, and they play a crucial role in maintaining overall bodily function. Arteries have thick walls, composed mainly of elastic tissue, which allows them to withstand the high pressure of blood flow from the heart.
Arteriodiastasis
Arteriodiastasis refers to the dilation or widening of blood vessels, particularly arteries, due to increased blood flow or pressure. It is a normal physiological response that occurs when blood vessels expand to allow for better blood circulation and delivery of oxygen and nutrients to tissues. This process can also be induced during medical procedures, such as angiography, to enhance the visibility of blood vessels on imaging scans.
Arteriodilator
An arteriodilator is a substance or medication that causes the dilation, or widening, of arteries. This leads to an increase in blood flow and can lower blood pressure, improve circulation, or enhance the delivery of oxygen and nutrients to tissues.
Arteriofibrosis
"Arteriofibrosis" refers to the abnormal development of fibrous tissue in the walls of arteries, leading to thickening and stiffening of the arterial walls. This can affect blood flow and may contribute to cardiovascular diseases.
Arteriogram
An arteriogram, also known as an angiogram, is a medical imaging procedure used to visualize the arteries. It involves injecting a contrast dye into an artery, typically through a catheter, which then highlights the blood vessels on X-ray images or CT scans. This allows doctors to examine the flow of blood, detect blockages, narrowing, or other abnormalities in the arterial system. It is commonly used to diagnose conditions such as atherosclerosis, aneurysms, or peripheral arterial disease.
Arteriograms
An arteriogram, also known as an angiogram, is a medical imaging procedure used to visualize the arteries, typically to detect blockages or abnormalities.

Arteriography
Arteriography is a medical imaging technique used to visualize the arteries, typically to diagnose and assess any blockages or abnormalities. It involves injecting a contrast dye into an artery, which allows the arteries to show up clearly on X-rays or CT scans, providing detailed images of their structure and blood flow. This procedure is also known as arteriogram or angiography.
Arteriolar
"Arteriolar" refers to something related to arterioles. Arterioles are small blood vessels that branch directly from arteries and play a crucial role in regulating blood pressure and controlling blood flow to different tissues in the body. They have muscular walls that can constrict or dilate, thus influencing the resistance to blood flow and the delivery of oxygen and nutrients to tissues.
Arteriole
An arteriole is a small, branch-like blood vessel that branches off from an artery and serves to further divide the artery into smaller vessels. Arterioles are an important part of the circulatory system, as they help to regulate blood pressure and blood flow. They are also responsible for delivering oxygenated blood to the capillaries, where it is exchanged with waste products and nutrients.
Arterioles
Arterioles are small blood vessels that branch off from the larger arteries and lead to the capillaries. They are controlled by the body's autonomic nervous system and help regulate blood pressure and blood flow to specific organs and tissues.
Arteriolitis
Arteriolitis refers to inflammation of the arterioles, which are small blood vessels that carry oxygenated blood away from the heart to the body's tissues. This condition can lead to narrowing or blockage of these vessels, potentially affecting blood flow and causing various health issues depending on the location and severity of the inflammation.
Arteriology
Arteriology is the branch of medicine that deals with the study of arteries, their structure, function, and diseases affecting them. It focuses on the blood vessels that carry oxygenated blood away from the heart to different parts of the body and encompasses topics such as arterial anatomy, physiology, and pathologies like atherosclerosis or aneurysms.
Arteriolonecrosis
Arteriolonecrosis is a medical condition characterized by the death of small blood vessels (arterioles) due to a lack of blood flow. This can lead to the formation of scar tissue, which can cause inflammation and damage to surrounding tissues. Arteriolonecrosis is often seen in conditions such as hypertension, diabetes, and atherosclerosis, and can lead to complications such as kidney failure, heart disease, and stroke.
Arteriomalacia
Arteriolosclerosis is a condition characterized by the hardening and narrowing of small arteries (arterioles) due to a buildup of plaque or deposits on their walls. This can lead to reduced blood flow and can contribute to various health problems, such as high blood pressure, heart disease, and stroke.
Arteriomegaly
Arteriomegaly refers to the abnormal enlargement of arteries, which are the blood vessels that carry oxygenated blood away from the heart to various parts of the body. This condition can be caused by various factors such as genetic disorders, high blood pressure, or diseases affecting the blood vessels. It may lead to complications if not addressed, as enlarged arteries can disrupt normal blood flow and potentially cause health issues depending on which arteries are affected.
Arterionecrosis
Arterionecrosis refers to the death of tissue caused by the obstruction or severe reduction of blood flow in an artery. It is a condition where the lack of oxygen and nutrients due to impaired arterial circulation leads to cell damage and eventually necrosis (tissue death). This can result from various factors such as atherosclerosis, thrombosis, embolism, or external injury.
Arteriopathy
Arteriopathy refers to a disease or disorder of the arteries, which are the blood vessels that carry oxygenated blood from the heart to the rest of the body. It can be caused by a variety of factors, including atherosclerosis (the buildup of plaque in the arteries), inflammation, or injury. Symptoms of arteriopathy may vary depending on the specific location and severity of the condition, but can include pain or cramping in the legs, chest pain, heart attack, or stroke.
Arterioplasty
Arterioplasty is a surgical procedure to repair or reconstruct damaged or narrowed arteries. It involves widening or restoring the normal flow of blood through the affected artery, often by removing blockages, placing stents, or using grafts to bypass the damaged section. This procedure can help improve blood circulation and reduce symptoms related to arterial narrowing, such as those seen in peripheral artery disease.
