Application of thoracoabdominal aorta mixed reality technique in aortic dissection
Objective:To explore the clinical application value of mixed reality technique and computed tomo-graphy angiography(CTA)technology in the diagnosis and treatment of Stanford type A aortic dissection(STAAD).Methods:Eighty patients with thoracoabdominal aorta mixed reality or CTA were retrospectively collected and were divided into group A(thoracoabdominal aorta mixed reality group)and group B(thoracoabdominal aorta CTA group)according to the different study purposes.CTA data generated by group A were import into visual three-di-mensional(3D)modelling software for 3D modelling to complete the display of mixed reality results;Group B un-derwent 3D-CT reconstruction of thoracoabdominal aorta.The general data of the two groups of patients were ana-lyzed by independent sample t test.Two groups of counting data were tested by χ2 test.Wilcoxon test was used for grade data.Kruskal-Wallis test was used to compare continuous variables.Kappa test was used to evaluate the sub-jective consistency of the evaluator.The perioperative indicators and clinical application value of the two groups were compared.Results:There was no significant difference in age,weight,height,sex,body mass index,hyper-tension,cardiovascular disease,cerebrovascular disease,diabetes and DeBakey classification between the two groups(all P＞0.05).Compared with group B,group A decreased about 15%,24%,20%,22%and 20%in operation time,extracorporeal circulation assistance time,aortic block time,selective cerebral perfusion time and intraoperative plasma infusion.The subjective score of the clinical application value of group A in the four aspects of operation plan formulation,real-time intraoperative navigation,remote consultation and doctor-patient communica-tion was higher than that of group B(all P＜0.05).Conclusion:Compared with traditional thoracoabdominal aorta CTA,thoracoabdominal aorta mixed reality can more effectively improve perioperative indexes in the treatment of a-cute STAAD operation,and has advantages in surgical plan formulation,real-time intraoperative navigation,remote consultation,and doctor-patient communication.
