Clinical Application Value of 3D Printing Assisted Technology for Short Neck Complex Abdominal Aortic Aneurysm
Objective To explore the clinical application value of 3D printing assisted technology for short neck complex abdominal aortic aneurysm(AAA).Methods A total of 60 patients with AAA of short proximal neck were retrospectively ana-lyzed.According to using 3D printing assisted technology or not,they were divided into routine intervention group(n =32)and 3D printing group(n = 28).The routine intervention group underwent abdominal aortic CT angiography(CTA),while 3D printing group was additionally given 3D printing assisted technology.The differences in the results between preoperative prediction and in-traoperative measurements[the maximum diameters of tumor neck,tumor cavity and tumor,the angle between tumor neck and normal abdominal aorta(angle a),the angle between tumor neck and the middle axis of abdominal aorta(angle b)]were com-pared between the 2 groups.The maximum diameters of true cavity,false cavity and tumor were recorded before and at 3 months after surgery.Results There was no significant difference between the preoperative evaluation results and the intraoperative measurement results of the maximum diameter of tumor neck,cavity and body between the 2 groups(P>0.05).However,there were some differences between preoperative evaluation and intraoperative measurement of Angle a and Angle b in the conventional intervention group(P<0.05).Three months after surgery,the true cavity diameter expanded,the false cavity diameter and the tumor diameter shrank in both groups,and the changes were more significant in the 3D printing group(P<0.05).Conclusion The application of 3D printing assisted technology in abdominal aortic CTA can accurately restore and and reconstruct images,which play positive roles on preoperative evaluation,choice of surgical plans and surgical effect in patients with AAA of short proximal neck.
