Abstract/OtherAbstract:
PURPOSE: The purpose of this study was to report a new computed tomography (CT) finding in acute cardiac tamponade: a contrast-fluid level in the hepatic inferior vena cava (IVC) during an arterial dominant phase CT study (IVC niveau sign) in patients with acute type A aortic dissection. MATERIALS AND METHODS: We retrospectively reviewed CT studies with the diagnosis of proximal aortic dissection (Stanford type A) with acute cardiac tamponade. There were 12 patients enrolled in the study (6 women, 6 men; mean age 66 years). A total of 62 patients were selected as a control chronic pericardial effusion group to compare with the acute cardiac tamponade group. RESULTS: Among the 12 patients with acute cardiac tamponade, the IVC niveau sign was seen in 7 (58%). In the control chronic pericardial effusion group (n = 62), we identified the IVC niveau sign in only one patient (1.6%). There was a significant difference in the presence of the IVC niveau sign between the acute cardiac tamponade and chronic pericardial effusion groups (P < 0.0001). CONCLUSION: The presence of the IVC niveau sign suggests acute cardiac tamponade in patients with acute type A aortic dissection.
