The risk of rupture of an AAA is related to its diameter; once the aneurysm reaches about 5 cm, the yearly risk of rupture may exceed the risks of surgical repair for an average-risk patient. Rupture risk is also related to shape; so-called "fusiform" (long) aneurysms are considered less rupture-prone than "saccular" (shorter, bulbous ...
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 .
Small aneurysms (less than 7 mm) have a low risk of rupture and increase in size slowly. [44] The risk of rupture is less than one percent for aneurysms of this size. [44] The prognosis for a ruptured cerebral aneurysm depends on the extent and location of the aneurysm, the person's age, general health, and neurological condition. Some ...
A ruptured aneurysm can cause critical health problems, including a hemorrhagic stroke, brain damage, coma and even death. ... “Although there can be a hereditary risk, most [ruptured] aneurysms ...
An aortic aneurysm often doesn’t cause symptoms, but it can lead to severe, sudden bleeding from a ruptured aneurysm. A ruptured aneurysm has a high risk of death. If symptoms of an aortic ...
Diagnosis of a ruptured abdominal aortic aneurysm (rAAA) is challenging, with a wrong diagnosis occurring in between 32 and 42 % of cases. Such errors further increase the mortality risk due to incorrect first response and treatment. In cases of misdiagnosis, aortic rupture is often mistaken for ureteric colic and myocardial infarction (MI). [3]
A ruptured aneurysm typically leads to an aortocardiac shunt and progressively worsening heart failure. [2] An aneurysm of the aortic sinus may rupture due to infective endocarditis involving the aortic wall and tertiary-stage syphilis. [citation needed] The manifestations appear depending on the site where the sinus has ruptured.
Surveillance is indicated in small asymptomatic aneurysms (less than 5.5 cm) where the risk of repair exceeds the risk of rupture. [52] As an AAA grows in diameter, the risk of rupture increases. Surveillance until an aneurysm has reached a diameter of 5.5 cm has not been shown to have a higher risk as compared to early intervention. [55] [56]
