Why the study?
Does contrast-specific sonography accurately diagnose ruptured abdominal aortic aneurysm in patients with suspected rupture?
Does contrast-specific sonography accurately diagnose ruptured abdominal aortic aneurysm in patients with suspected rupture?
Contrast-enhanced sonography may serve as an effective, rapid, and noninvasive bedside alternative to CT for the emergency diagnosis of ruptured abdominal aortic aneurysms.
May aid rapid bedside diagnosis of ruptured AAA; leaves open prospective validation before clinical adoption.
OBJECTIVE: We describe the contrast-specific sonography features of ruptured abdominal aortic aneurysm, and we hypothesize that this technique would be useful for emergency imaging of patients with suspected aneurysm rupture. CONCLUSION: We used contrast-specific sonography to assess eight patients with ruptured abdominal aortic aneurysm. Five of these cases were correlated with CT findings. We found that contrast-enhanced sonography can reveal features specific for ruptured aortic aneurysm without causing a significant delay in surgery. This technique may be as effective as CT but may allow a more rapid and noninvasive diagnosis, especially when sonography can be performed bedside.
