2024年10月4日 · Aortic aneurysms are focal or diffuse dilatations of the aorta involving all three aortic wall layers. Most aneurysms are caused by atherosclerosis, whilst trauma, infection, and genetic syndromes are other causes. The broad term aortic aneurysm is usually reserved for pathology discussion.

2025年1月17日 · Thoracic aneurysms are often incidental findings on chest imaging. They may present symptomatically if large enough to cause mass effect on the airway, esophagus or pulmonary vasculature. Alternatively, they may present due to a complication, including rupture, dissection, aorto-bronchial or aorto-esophageal fistulae .

2023年8月8日 · This activity reviews the use of point of care ultrasound in diagnosing abdominal aortic aneurysms and highlights the role of the interprofessional team in evaluating and treating patients who have abdominal aortic aneurysms.

2024年7月26日 · Ascending aortic aneurysms are defined as a permanent dilatation of the ascending aorta ≥1.5 times the expected normal diameter or ≥5 cm in people <60 years. An ascending aortic diameter ≥4 cm is considered dilatation 7. True aneurysms can result from a wide variety of conditions:

This review will summarize the imaging evaluation and underlying pathology relevant to the diagnosis of thoracic aortic aneurysm. Key Points: Cross-sectional imaging (CTA and MRA) plays a central role in management of patients with thoracic aortic aneurysm

2019年3月19日 · Thoracic aortic aneurysm (TAA) represents aneurysmal dilatation of the ascending thoracic aorta, the aortic arch, or the descending thoracic aorta, or a combination of these locations. The...

In this review we will briefly summarize the current techniques (e.g. ultrasound, computed tomography, and magnetic resonance imaging) for anatomical imaging of AAA. We also discuss the various functional imaging techniques that have been explored for AAA imaging.

2013年12月10日 · Rarely: Thoracic (chest) aortic aneurysms can sometimes be seen on chest x-rays. The more common abdominal ones need an ultrasound or a ct scan to detect them. Albert einstein died from a ruptured abdominal aortic aneurysm. Not often: It can only be seen on a chest x-ray if the aneurysm is calcified.

2015年12月26日 · Oblique axial (A) and oblique sagittal (B) maximum intensity projection CT angiographic images show an aneurysmal descending thoracic aorta with considerable mural thrombus (arrow) and atherosclerotic calcifications.
