Since most AAAs are asymptomatic unless they leak or rupture, they are commonly diagnosed incidentally during imaging for other indications.

Uncommonly, unruptured aneurysms may present with abdominal or back pain. Large aneurysms may present as a pulsatile abdominal mass. The most significant complication is abdominal aortic rupturewhich presents with severe abdominal or back pain, hypotension, and shock.

An aneurysm may be visible as an area of curvilinear calcification in the paravertebral region on either abdominal or lumbar spine radiographs. Although not adequate for AAA detection or follow-up, x-ray may be sufficient for initial detection and diagnosis. Ultrasound is optimal for general AAA zorta and surveillance, because it is fast, spares the use of ionizing radiation and intravenous contrast, and is relatively inexpensive. Although excellent for following lesions, ultrasound does not provide sufficient detail for procedural planning or more complex lesions.

Given a reported range in measurement error of 4 mm 12ultrasound cannot be reliably used in evaluation for endovascular treatments and assessment of regional branch vessels. CT angiography CTA is abdomlnal the gold standard for evaluation, but exposes the patients to high radiation doses.

It is excellent for pre-operative planning as it accurately delineates the size and shape of abddominal AAA and its relationship to branch arteries and the aortic bifurcation.

Oblique reformations enable accurate measurements in non-orthogonal planes. CTA is superior to ultrasound in detecting and measuring common iliac artery aneurysms. An increasing diameter of the aneurysmal sac of 5 mm over a 6-month interval or a diameter of 7 cm are also considered to be at high risk for rupture and warrant urgent repair. Offers lack of ionising radiation, but is more costly, less widely available, and the examination is substantially lengthier.

Catheter-based angiography alone is inadequate for pre-procedural evaluation of AAA. While digital subtraction angiography DSA is superb for delineating regional branch vessels, it can be misleading and mask true aneurysm size in the setting of mural thrombus.

Certain features and relevant negatives regarding AAA should be included in the radiology report – especially if this is a new or undocumented finding:. The natural history of abdominal aortic aneurysms is variable; some small aneurysms do not appear to change, while others slowly expand and become at risk for eventual rupture 19, A number of clinical factors e.

Ultimately, the primary clinical question is whether and when to intervene in order to avoid aortic rupture. In terms of imaging, there remains debate about the best criteria for predicting AAA rupture and therefore indications for operative intervention.

Prognostic imaging criteria include:. In patients with a connective tissue disorder e. Marfan syndromeespecially those with a bicuspid aortic valvesurgical treatment may be considered even with a diameter smaller than 5.
