The CT appearances of ruptured abdominal aortic aneurysms.
There is no place for investigative CT scans in patients who have the classical triad of abdominal aortic aneurysm rupture, namely excruciating abdominal pain or backache, a pulsatile mass and hypotension. These patients require immediate surgery. However, in the absence of this triad, CT scans play an important role in the diagnosis of abdominal aortic aneurysm rupture. The CT scan findings will dictate whether the patient requires immediate surgery as in the case of acute rupture, or, whether the surgery can be delayed up to 24 hours to allow for stabilisation and hydration, as in the case of subacute and chronic rupture.
