Aortic rupture is a surgical emergency and has a high mortality even with prompt treatment. Weekend admission for a ruptured aortic aneurysm is associated with increased mortality compared with admission on a weekday, and this is likely due to several factors including a delay in prompt surgical intervention. [16]
Aortic rupture is a rare, extremely dangerous condition that is considered a medical emergency. [1] The most common cause is an abdominal aortic aneurysm that has ruptured spontaneously. Aortic rupture is distinct from aortic dissection , which is a tear through the inner wall of the aorta that can block the flow of blood through the aorta to ...
Therefore, aortic injury is on a scale from injury to a part of the inner layer to a complete tear of all three layers. [7] There are 4 grades of aortic injury. [1] Type I: Intimal tear; Type II: Intramural hematoma; Type III: Pseudoaneurysm; Type IV: Rupture; In addition to the 4 grades of aortic injury, the risk of rupture can also be ...
As an aneurysm increases in size, the risk of rupture, which leads to uncontrolled bleeding, increases. [2] Although they may occur in any blood vessel, particularly lethal examples include aneurysms of the circle of Willis in the brain, aortic aneurysms affecting the thoracic aorta , and abdominal aortic aneurysms .
Among those with an aneurysm between 5.5 and 7 cm, the risk is about 10%, while for those with an aneurysm greater than 7 cm the risk is about 33%. [1] Mortality if ruptured is 85% to 90%. [ 1 ] Globally, aortic aneurysms resulted in 168,200 deaths in 2013, up from 100,000 in 1990.
Aneurysms may affect the right (65–85%), non-coronary (10–30%), or rarely the left (< 5%) coronary sinus. [1] These aneurysms may not cause any symptoms but if large can cause shortness of breath, palpitations or blackouts. Aortic sinus aneurysms can burst or rupture into adjacent cardiac chambers, which can lead to heart failure if untreated.
Inflammatory Aortic Aneurysms occur typically in a younger population compared to the typical Abdominal Aortic Aneurysm group. Risk of rupture for the IAA group, due to thinning of aneurysm walls, are also rare due to inflammation and fibrosis [4] Unruptured inflammatory AAAs are usually symptomatic: [citation needed] abdominal or back pain (70 ...
The condition can be mimicked by a ruptured cyst of the pericardium, [11] ruptured aortic aneurysm [10] and acute coronary syndrome. [12] Misdiagnosis is estimated at 39% and is associated with delays correct diagnosis and improper treatment with anticoagulants producing excessive bleeding and extended hospital stays. [12]
