Abstract
Objective To compare the value of noncontrast CT scan and CTA in the clinical application of aortic dissection. Methods Thirty-two cases of aortic dissection admitted in Xiaogan Central Hospital from February 2008 to June 2011 were retrospectively analyzed. All patients took CTA after CT scan and the results were compared, of which, 15 cases took emergency CT followed with CTA the next day, and other cases took CTA right after noncontrast CT scan. Results Among 32 cases of aortic dissection, 21 ones were typical aortic dissection, 11 ones were atypical aortic dissection (intramural hematoma). According to the Stanford classification, 10 cases were type A, 22cases were type B. In the 21 typical aortic dissection cases, 20 cases showed torn intima in CT scan, 1 case only presented aorta widen. CTA showed enhancement in both true and false lumen. 2 cases displayed calcification shifted with torn intima. In the 11 atypical aortic dissection cases, CT scan showed high density thickening of the aortic wall in semilunar or ring pattern, with a thickness of over 5 mm, the hematomas were unenhanced and appeared as semilunar or ring low density area, 7 cases were accompanied with intima calcification shift, 3 cases with intima leakage, 5 cases with penetrating ulcer. Among the 15 cases with' atherosclerotic change, 4 cases showed pericardial effusion, 24 cases showed pleural effusion. Conclusion CTA is more specific for the di-agnosis of aortic dissection than uncontrast CT scan, however, uncontrast CT scan can provide valuable information for the diagnosis of aortic dissection, especially for emergency patients with limited time and condition for CTA.
