ABSTRACT
Objective:To explore the value of fusion imaging in the treatment of complex aortic pathology.Methods:A retrospective analysis was conducted of 29 patients with complex aortic pathology who underwent treatment with endovascular aortic repair using fusion imaging (FI+ ) technique or without FI (FI-) between June 2015 and June 2021. The perioperative outcomes and morbidity of the FI was assessed and the early results of follow up were evaluated.Results:The mean age of patients was (70.3±7.3) years old, and 24 (82.8%) males. Technical success was 96.5% (28/29). The FI+ group patients had lower procedure time[FI+ , (209±53) min vs. FI-, (306±24)min, P=0.005]and ionic contrast medium[(169±23)ml vs. (201±20)ml, P=0.040]. Contrast-induced acute kidney injury (CI-AKI)[3.4%(FI+ 0 vs. FI-6.7%, P=0.33)], and operation-related reintervention[6.9%(FI+ 0 vs. FI-13.3%, P=0.16)] were similar. There were no significant differences in blood loss, fluoroscopy time. Conclusion:FI technique improves the accuracy during positioning in complex endovascular aortic repair, could reduce aortic related reintervention rate, operation time and contrast dose. Further studies and development are needed to obtain optimal image quality and higher precision.
