To describe Computed Tomography Angiography (CTA) imaging findings that might be related to complications of aortic aneurysm;
To identify and exemplify pre- and post-operative instability signs of aortic aneurysm;
To emphasize the critical role of radiologists during evaluation of aortic aneurysm patients,
especially when instability signs are present;
• estimated at 1.4% among patients between 50 and 84 years old in the United States (US)¹;
•∼ 15,000 annually in the US² (∼12,500 abdominal aortic aneurysm and ∼ 2,000 thoracic aortic aneurysm³);
•∼ 6,000-8,000 annually in the United Kingdom³;
•In patients with abdominal aortic aneurysm rupture: 53,1% in the US and 65,9% in England 4
Computed Tomography Angiography
The “gold standard” imaging examination for diagnosis and follow-up¹;
Excellent for pre-operative planning,
especially for endovascular aneurysmrepair (EVAR) and for...
Findings and procedure details
CTA aneurysmal instability signs:
Pre-operative signs ( Fig. 3 );
Post-operative signs ( Fig. 4 );
Aneurysmal related fistulas ( Fig. 5 );
• Aortic aneurysm complications should always be part of differential diagnosis during onset acute and subacute patient’s complaints;
arterial and venous phase CTA can provide sufficient data to support a good analysis of aortic aneurysm complications;
• Fast and correct detection of aortic aneurysm instability signs at CTA by radiologists,
might provide best outcomes for patients;
• Radiology and cardiovascular/endovascular surgery staff should have efficient communication to guide aortic aneurysm instability patients through proper treatment.
