What does CAS mean in MEDICAL
Carotid artery stenosis (CAS), is a narrowing of the carotid artery in the neck region, which carries oxygen-rich blood to the brain. The condition can be caused due to fatty deposits known as plaque, which can build up on the carotid arteries. CAS is considered an important risk factor for stroke, and early diagnosis and treatment is essential to reduce this risk.

CAS mostly used in an acronym Medical in Category Medical that means carotid artery stenosis
Shorthand: CAS,
Full Form: carotid artery stenosis
For more information of "carotid artery stenosis", see the section below.
Definition
CAS stands for carotid artery stenosis. It refers to a narrowing of one or both of the two main arteries that carry oxygen-rich blood from the heart to the brain. This process decreases blood flow through these vessels, but it can also increase risk of stroke if left untreated.
Causes
CAS occurs due to a buildup of fat, cholesterol and other substances called plaque on the inner lining of one or both carotid arteries. These deposits are thought to be caused by high cholesterol levels or other conditions such as diabetes or smoking. Plaque also becomes thicker with age and can further narrow the arteries, resulting in CAS.
Symptoms
Most patients with CAS will not present with any symptoms until later stages of narrowing when it has become severe enough to cause blockage in blood flow. However, some symptoms may include dizziness, headache, vision changes or difficulty speaking or understanding speech (aphasia). These difficulties may worsen over time due to decreased oxygen supply going to the brain and increases in stroke risk associated with embracement.
Diagnosis
To diagnose CAS, doctors rely on imaging tests such as CT angiogram (CTA) or magnetic resonance angiography (MRA). In some cases, ultrasound may also be used if there isn’t evidence of significant narrowing on imaging tests. During these tests, doctors look at pictures taken by special cameras that show what’s happening inside your body – including any narrowings found in your carotid arteries.
Treatment
Treatment for CAS depends on its severity and your individual medical history and overall health status. Generally speaking, lifestyle modifications such as quitting smoking and changing diet are advised accompanied by medications that lower cholesterol levels such as statins or ACE inhibitors. For more serious cases, interventional treatments such as stenting may be required.
Essential Questions and Answers on carotid artery stenosis in "MEDICAL»MEDICAL"
What is carotid artery stenosis?
Carotid artery stenosis is a narrowing of the carotid arteries, which are the major blood vessels that supply oxygen to the brain. Stenosis can occur due to plaque buildup in the walls of these arteries, known as atherosclerosis. This restricts blood flow to your brain and increases your risk for stroke
Final Words:
CAS is a common medical condition resulting from build up of fat particles on inner lining of carotid artery leading to its narrowing causing decrease in blood supply towards brain leadingto various issues including stroke if not prevented in timely fashion . Diagnostic imaging studies like CTA/MRA are used for prelim detection &treated accordingly using lifestyle changes& medications . Interventional therapies like stenting are availablefor severe forms only .
