Acute aortic syndrome

Acute Aortic Syndrome

Acute aortic syndrome (pronunciation: a-kyoot ao-rik sin-drohm) is a term used to describe a group of conditions that involve the aorta, the main blood vessel that carries blood from the heart to the rest of the body. These conditions include aortic dissection, intramural hematoma, and penetrating atherosclerotic ulcer.

Etymology

The term "acute" comes from the Latin "acutus", meaning sharp or pointed, and is used in medicine to describe conditions that have a rapid onset and require urgent care. "Aortic" refers to the aorta, and "syndrome" comes from the Greek "syndromē", meaning concurrence of symptoms, indicating a group of symptoms that consistently occur together.

Conditions

Aortic Dissection

An aortic dissection is a serious condition in which the inner layer of the aorta tears. Blood surges through the tear, causing the inner and middle layers of the aorta to separate (dissect).

Intramural Hematoma

An intramural hematoma is a variant of aortic dissection. It is characterized by bleeding into the wall of the aorta without an identifiable intimal tear.

Penetrating Atherosclerotic Ulcer

A penetrating atherosclerotic ulcer is a condition that occurs when an atherosclerotic plaque in the aorta ulcerates and penetrates through the internal elastic lamina into the media of the aortic wall.
