Value of 128-slice spiral CT angiography in the diagnosis of aortic dissection

Objective To evaluate the value of 128-slice CT angiography in the diagnosis of aortic dissection. Methods From 2011 to 2013, 28 patients with aortic dissection who were taken CT angiography in our hospital were included in this retrospective analysis. Their clinical characteristics, the extent of dissection and the imaging features in spiral CT angiography were explored. Results Based on the DeBakey classification, there were 8 cases of type Ⅰ, 2 cases of typeⅡ, 18 cases of type Ⅲ aortic dissection. All the aortic dissections had true and false lumen, the location of crevasse and the numbers of break branches were clearly revealed. Multiple crevasses were shown in 6 cases. There were 2 cases of atypical aortic dissection. Conclusion 128-slice spiral CT angiography can accurately determine the direct findings, provide precise imaging information and assist surgeons to choose treatment options.
