2025年1月24日 · Penetrating atherosclerotic ulcers (PAU) are pathologies that involve the aortic wall and along with aortic dissection and aortic intramural hematoma, form the spectrum of acute aortic syndrome.

What is an Aortic Ulcer? Sometimes called a penetrating aortic ulcer, this irregularity of the aortic wall is caused by the formation of plaque from atherosclerosis. The plaque wears down the inner lining of the aorta, which is the largest blood vessel in the body and branches off from the heart.

Penetrating aortic ulcers are usually an incidental finding on CT or MR. On CT look for contrast that is separate from the main aorta channel. An ulcer is sometimes hard to distinguish from an ulcerated plaque. An ulcerated plaque is actually not considered part of the “acute aortic syndrome” spectrum (it is more in line with a “regular ...

What Is an Aortic Ulcer? The largest artery in the human body, the aorta is the main blood vessel that carries oxygenated blood from the heart to the rest of the body. Sometimes referred to as a penetrating aortic ulcer, an aortic ulcer is caused by atherosclerosis (a buildup of plaque in the inner lining of an artery) in the aorta.

The term “penetrating aortic ulcer” refers to an ulceration of an atheromatous plaque that extends deeply through the intima and into the aortic media. It may precipitate an intramedial dissection (usually localized) or may rupture into the adventitia to form a pseudoaneurysm.

Ulcers can form in the aorta from plaque that wears away at the artery wall lining and penetrates the artery wall. Previously, this condition was considered a form of aortic dissection because it is similar and often has similar symptoms.

Penetrating atherosclerotic ulcer (PAU) of the aorta was described by Shennan in 1934 with Vilacosta, and Roman coined the term acute aortic syndrome in 2001. 1 Recently, terms like incomplete dissection and intimomedial flap are introduced. 2,3 PAU targets aortic intima with loss of integrity manifesting as aortic dissection (AD). 4,5,6 PAU ...

Fatty clumps in the blood called plaque can build up in the aorta and form an ulcer, or cratering, over time. The ulcer can penetrate the wall of the aorta, decreasing blood flow and allowing blood to leak and cause internal bleeding. Having an aortic ulcer puts you at risk for aortic dissection, a tear in the aorta that could rupture. Aortic ...

2020年5月15日 · Penetrating aortic ulceration (PAU) is part of the spectrum of acute aortic syndromes (AAS), and is defined as an ulcerated intimal disruption due to atherosclerotic disease. PAU may be simple, isolated and asymptomatic, or it may be symptomatic, aneurysmal and extensive; these may progress and lead to rupture.

Purpose of review: Penetrating aortic ulcer (PAU) is defined as ulceration of an aortic atherosclerotic plaque penetrating through the internal elastic lamina into the media. With the advances in imaging techniques, the differential diagnosis between PAU and other aortic ulcers remains a challenge.
