PDFAbstract
Objective To explore the value of CT three-dimensional (3D) reconstruction in diagnosing and typing aortic dissection. Methods Seventy-two cases of patients with aortic dissection who were admitted in our hospital between April 2011 and December 2015 were selected as the study objects. All patients underwent CT plain scan, enhanced scan and 3D reconstruction. The CT findings and diagnostic accuracy were recorded. Results CT typical findings of aortic dissection included tube wall high density crescent signs, calcified plaque ingression and high density line-like intimal signs in lumens. The typing and diagnostic accuracy rates of plain scan and enhanced scan were 91.7%and that of 3D reconstruction was 100% (P<0.05). Conclusion The application of CT 3D reconstruction in patients with DeBakey I-III type aortic dissection can visually display the initial rupture and intimal flap, true and false lumens. It is conductive to confirming the lesions and involved range and helps to type. The diagnostic accuracy rate is higher. It is an ideal inspection method for aortic dissection.
