Learning objectives

Learning objective Briefly describe the key anatomical points of the aorta and how to asses an aortic aneurysm. Describe and illustrate the semiological characteristics of the main complications of aortic aneurysms. Show the importance and main aspects of a structured radiological report.

Background

Background I. The aorta The aorta is the largest and main artery of the body carrying oxygenated blood from the heart to all the organ systems. Ithas three histological layers:Fig. 1 intima - thin endothelial layer; media - elastic lamella, smooth muscle and connective tissue; adventitia – connective tissue, nerves, lymphatics and the vasa vasorum; It can be divided into the following segments and subsegments:Fig. 2 The thoracic aorta segments: ascending aorta, aortic arch, descending aorta The abdominal aorta with: suprarenal, juxtarenal and infrarenal abdominal...

Findings and procedure details

CT PROTOCOL We used the following multidetector CT protocol: oNon enhanced; oPost-contrast acquisitions; oMultiplanar reconstructions (axial, saggital, coronal, curved and MIP) Out of the 156 studied cases, 62,9% presented with suspicion or diagnosis of abdominal aneurysm and aneurismal complications and 37,1% were incidental findings. CT FINDINGS Thrombosis 1.Asses and measure Fig. 6 : In most cases of complicated aortic aneurysms the vessel wall is covered by an intraluminal thrombus, which generally does not obstruct blood flow. 2.Check aortic branches Fig. 7 / adjacent organs Fig....

Conclusion

CONCLUSIONS: · CT angiography represents thegold standard imaging method for the diagnosis and assessment of complicated aortic aneurysms. · In any CT exam it is important to thoroughly examine the entire aortic artery and its branches, but also the adjacent structures that might be implicated. · The information provided in a structured report, allows for a rigorous stadialization for proper future management.
