“…The latter is characterized by an extended echoic intimal flap, attached on both ends to the aortic wall. 16 Instead, we describe the floating layer as an irregular flap, detached focally from the aneurysm thrombus on 1 side and freely floating within the aneurysm lumen. Thrombus interruption was seen as a defined tear of the lumen-to-thrombus interface, usually spreading within the thrombus itself in combination with inhomogeneously hypoechoic intrathrombotic foci.…”

Objective. The purpose of this study was to categorize the sonographic findings seen in patients with a ruptured abdominal aortic aneurysm (AAA) and to describe 3 previously undescribed sonographic findings. Methods. From January 1997 to December 2003, we evaluated 388 consecutive patients with an AAA (transverse aortic diameter >30 mm). Among these patients, 29 had surgical or computed tomographic demonstration of aneurysm rupture. The remaining 359 were asymptomatic and had no evidence of AAA rupture at follow-up. Results. Findings recognized among 29 positive cases included AAA deformation (n = 12), luminal thrombus inhomogeneity (n = 20), clear interruption of a luminal thrombus (n = 5), retroperitoneal hematoma (n = 22), and hemoperitoneum (n = 11). In addition, 3 previously unreported findings were noted: an intraluminal floating thrombus layer (n = 8), a parietal hypoechoic focus due to aneurysm wall interruption (n = 3), and a para-aortic hypoechoic area adjacent to the bleeding side (n = 4). Aside from AAA deformation and thrombus heterogeneity, no other signs were recognized among subjects with a nonruptured aneurysm. Conclusions. In the past, sonography has been used mainly to rapidly confirm aneurysm presence in the clinical setting of a patient with a suspected rupture. Instead, this retrospective series shows how this imaging technique can frequently identify several direct and indirect signs of aneurysm rupture itself. Moreover, 3 new indicators of AAA rupture have been observed.

“…In our series, such modalities were unable to assess the diagnosis, to evaluate the proximal and distal limits of the dissection, and to determine the associated involvement of visceral arteries, probably because of retroperitoneal hematoma and the associated lesions. Moreover, this examination is frequently unable to show short intimal flaps 17,18 and requires well-trained operators that are not always available in emergency.…”
