Abstract：Objective: To investigate the application value of CT angiography (CTA) combined with digital subtraction angiography (DSA) in the diagnosis and treatment of thoracoabdominal aortic aneurysms. Methods: A total of 190 patients with suspected thoracoabdominal aortic aneurysm who were admitted to the hospital from July 2016 to May 2018 were enrolled. All underwent DSA and CTA. The diagnosis result and imaging result of the two methods were compared. Results: There was no significant difference in sensitivity, specificity and accuracy for aneurysms between CTA and DSA (P>0.05). There was no significant difference in tumor morphology, classification and location between the two methods (P>0.05). Conclusion: The combined examination with CTA and DSA for patients with thoracoabdominal aortic aneurysm can more accurately show the pathological features of aneurysms, and improve the accuracy of preoperative evaluation. In particular, conducting CTA to define diagnosis for patients with thoracoabdominal aortic aneurysm before the interventional treatment, choosing best projection angle according to the aneurysm morphology displayed by CTA in the surgery, and guiding DSA to select the appropriate angle could show more accurately show pathological features of aneurysms, improve the accuracy of evaluation before covered stent insertion. At the same time, the intraoperative radiation dose and contrast dose are significantly less.
