2022年6月29日 · Atherosclerosis in your aorta disrupts the normal flow of blood through your aorta and to the rest of your body. So, it raises your risk of ischemia (lack of oxygen-rich blood) in many different organs and tissues.

Atherosclerosis symptoms often don’t start until an artery is very narrow or blocked. Many people don’t know they have plaque buildup until they have a medical emergency like a heart attack or stroke. You may notice symptoms of atherosclerosis if your artery is more than 70% blocked.

2016年8月19日 · Symptoms result from aneurysmal change, especially in the abdominal aorta, with predisposition to rupture; embolic disease, from aortic arch vessels into the cerebral circulation, or abdominal aorta into visceral arteries; ulceration and intramural hematoma formation in the thoracic aorta; extension into mesenteric and renal arteries, with ...

Atherosclerosis is the buildup of fats, cholesterol and other substances in and on the artery walls. This buildup is called plaque. The plaque can cause arteries to narrow, blocking blood flow. The plaque also can burst, leading to a blood clot.

2023年11月7日 · Atherosclerosis causes heart attacks, strokes, and peripheral vascular disease. Learn about causes, symptoms, risk factors, diagnosis, and treatments.

2023年4月25日 · Thoracic aortic aneurysms are less common than aneurysms that form in the lower part of the aorta, called abdominal aortic aneurysms. Thoracic aortic aneurysms often grow slowly. There are usually no symptoms, making them difficult to detect. Many start small and stay small. Others grow bigger over time.

A thoracic aortic aneurysm is a bulge in the part of your aorta that runs through your chest. It forms when your aorta wall grows weak from plaque, connective tissue disorders or other factors. You may feel no symptoms until the aneurysm causes a medical emergency.

This review details the current state of knowledge about thoracic aortic atherosclerosis, including the clinical and pathologic evidence that it is an important embolic source, data which guide current therapy and future directions for clinical investigation.

We reviewed the imaging findings of thoracic aortic atherosclerosis and their clinical significance, the understanding of which has previously been derived from transesophageal echocardiography. We also reviewed the related developments in CT and MR imaging of atheromatous disease, including the characterization of plaque components on MR imaging.

Having atherosclerosis (say "ath-uh-roh-skluh-ROH-sis") of the aorta means that a material called plaque (fat and calcium) has built up in the inside wall of a large blood vessel called the aorta. This plaque buildup is sometimes called "hardening of the arteries."
