Abstract

Abstract

Objective To investigate the simultaneous ureter and abdominal aorta imaging technique, its clinical effect and application value in the open surgery of abdominal aortic aneurysm. Method From August 2021 to May 2023, 24 patients underwent open surgery in the Department of Cardiovascular Surgery, the Second Affiliated Hospital of Kunming Medical University, and the ureter and abdominal aorta were simultaneously imaged before surgery. Based on the adjustment of operating parameters and the results of the simultaneous development examination in these patients, the application of this technique in 24 cases of open surgery for abdominal aortic aneurysm was discussed, and the value of this technique for ureteral protection in open surgery for abdominal aortic aneurysm was expounded. Result During the simultaneous imaging of the ureter and abdominal aorta, CTA scans were performed 4-5 minutes after the first injection of 40 ml contrast agent. Most segments of the ureter were well displayed on CT and 3D images, and their contrast with surrounding tissues was relatively clear; There was no difference in the detection rate of ureteral abnormalities between simultaneous imaging of the ureter and abdominal aorta and intraoperative exploration （P > 0.05）. There was no ureteral injury in 24 patients who underwent open surgery, and there was a statistical difference in the incidence of ureteral injury compared to the control group of 20 patients （ P < 0.05）. Conclusion During the simultaneous imaging of the ureter and abdominal aorta, CTA scan performed 4-5 minutes after the first injection of 40 ml contrast agent showed good imaging of the ureter. It can clearly distinguish the ureter, abdominal aorta, and surrounding adhesive tissue, assist in ureteral localization, and its application in open surgery for abdominal aortic aneurysm can help to detect ureteral stenosis, peripheral adhesion, and other conditions before surgery, and avoid intraoperative ureteral injury.
