Abstract：Objective To evaluate the value of CTA volume rendering image fusion in endovascular abdominal aortic repair(EVAR).Methods Retrospective analysis of 60 cases of endovascular aneurysm repair(EVAR)at Beijing Anzhen Hospital,Capital Medical University,from November 2020 to October 2022.60 patients undergoing EV AR were divided into groups according to whether volume rendering technology was applied or not.Patients in the research group applied VR image fusion technology to conduct3D real-time path navigation,while patients in the control group were treated with regular endovascular techniques.Intraoperative data and follow-up results of two groups of patients were compared.Re-sults EVAR was successfully performed in all patients.Image fusion technology can display the three-dimensional spa-tial position relationship of abdominal aortic aneurysm in real-time during operation.The dosage of iodized contrast agent and radiation dose for operation in the study group was significantly lower than that in the control group,yet there was no significant difference in the fluoroscopy time between the two groups.Conclusion VR image fusion technology can provide a guiding value for EVAR,reducing the amount of contrast agent and radiation dose during operation.Using VR image fusion in EVAR is safe and effective.
