ABSTRACT Objective To investigate the efficacy and safety of Mixed Reality (MR)‐Assisted Thoracic Endovascular Aortic Repair (TEVAR). Methods We retrospectively analyzed 46 patients with aortic dissection who underwent TEVAR. In the Control Group, Computed Tomography Angiography (CTA) was performed on the thoracic and abdominal aorta, after which surgery was performed based on traditional 2D imaging data. In the observation group, the Star Map HoloLens Image System was used for data processing and 3D modeling, and preoperative analysis and intraoperative path guidance were conducted with the MR Microsoft HoloLens Headset. The communication time, satisfaction, and anxiety after communication, as well as the operation duration, intraoperative blood loss, postoperative complications, and rehabilitation of these two groups were analyzed. Results This study aimed to evaluate the perioperative outcomes of MR‐guided stent placement. A total of 46 patients were equally divided into the MR group and control group ( n = 23 each), with data analyzed via non‐parametric tests. Compared with the control group, the MR group exhibited significantly shorter operation duration (70.91 ± 8.533 vs. 77.48 ± 8.474 min, Z = −2.785, p = 0.005), fewer fluoroscopy times (3.74 ± 1.214 vs. 5.61 ± 1.530, Z = −3.813, p < 0.001), and less stent adjustments (1.65 ± 1.152 vs. 2.91 ± 1.411, Z = −2.765, p = 0.006), suggesting MR guidance may optimize perioperative efficiency. Conclusion Multimodal MR has an important auxiliary role in patient education, surgical planning, and accurate positioning of the surgical approach.
