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 ...
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]
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.
Incidence rates of cranial aneurysms are estimated at between 0.4% and 3.6%. Those without risk factors have expected prevalence of 2–3%. [14]: 181 In adults, females are more likely to have aneurysms. They are most prevalent in people ages 35 – 60 but can occur in children as well.
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.
The risk adjusted mortality rate (RAMR) is a mortality rate that is adjusted for predicted risk of death. It is usually utilized to observe and/or compare the performance of certain institution(s) or person(s), e.g., hospitals or surgeons. It can be found as: RAMR = (Observed Mortality Rate/Predicted Mortality Rate)* Overall (Weighted ...
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 ...
