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;
Aortic Aneurysm ⇒ Prevalence : • estimated at 1.4% among patients between 50 and 84 years old in the United States (US)¹; ⇒ Mortality: •∼ 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...
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; • Pre-contrast,
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...
