An aortic aneurysm is an enlargement (dilatation) of the aorta to greater than 1.5 times normal size. [1] Typically, there are no symptoms except when the aneurysm dissects or ruptures, which causes sudden, severe pain in the abdomen and lower back. [2] [3] The etiology remains an area of active research.
Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta. [1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. [2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body. The aorta normally has three small pouches that sit directly above the aortic valve (the sinuses of Valsalva), and an aneurysm of one of these sinuses is a thin-walled swelling.
Aortic dissection affects an estimated 2.0–3.5 people per every 100,000 every year. Studies from Sweden suggest that the incidence of aortic dissection may be rising. [46] Men are more commonly affected than women: 65% of all people with aortic dissection are male. The mean age at diagnosis is 63 years. [25]
Oliver's sign, or the tracheal tug sign, is an abnormal downward movement of the trachea during systole that can indicate a dilation or aneurysm of the aortic arch.. Oliver's sign is elicited by gently grasping the cricoid cartilage and applying upward pressure while the patient stands with their chin extended upward.
Familial aortic dissection or FAD refers to the splitting of the wall of the aorta in either the arch, ascending or descending portions. FAD is thought to be passed down as an autosomal dominant disease and once inherited will result in dissection of the aorta, and dissecting aneurysm of the aorta, or rarely aortic or arterial dilation at a young age.
A thoracic aortic aneurysm is an aortic aneurysm that presents primarily in the thorax. A thoracic aortic aneurysm is the "ballooning" of the upper aspect of the aorta, above the diaphragm. Untreated or unrecognized they can be fatal due to dissection or "popping" of the aneurysm leading to nearly instant death.
There are clinical predictors of an aortic injury. [6] The predictors include if a patient is older than 50, was an unrestrained patient, has hypotension, has a thoracic injury requiring thoracotomy, has a spinal injury, or has a head injury. [6] If four of these criteria are met their likelihood for an aortic injury is 30% [6]
