Learning objectives

To describe the main points the radiologist´s reports must include in an abdominal aortic aneurysm rupture in order to assure the diagnosis and to help the interventional radiologist or vascular surgeon plan the patient´s treatment.

Background

Abdominal aortic aneurysm (AAA) is a dilation of the abdominal aorta of more than 3 cm, and is found in 2%-4% of the population older than 50 years. This disease carries a considerable risk of rupture, mainly in those aneurysms with a big diameter, above all if greater than 7 cm, and therefore, a substantial risk of death. Over 80% of patients with ruptured AAA die before they get to be treated, percentage that can decrease to less than 10% when surgical or endovascular treatment...

Findings and procedure details

Computed tomography is useful not only for detecting signs of aneurysm´s rupture, but also for planning surgical and/or endovascular repair. Therefore, there are some essential points our radiological report must include in order to help chose the most suitable treatment for the patients (Fig. 2): 1. Type of aneurysm (Fig. 3) a.Saccular: Those aneurysms that involve only part of a vessel wall. These type of aneurysms are rare (5% of abdominal aortic aneurysms), more frequently seen in infectious or inflammatory diseases, and usually located in...

Conclusion

Abdominal aortic aneurysm rupture is an emergency condition that requires the radiologists ability to look for the imaging features that will be determinant in the patients management, and the skill to be able to do it as fast as possible, as “Who does not know what to look for, does not understand what the findings are”.
