ABSTRACT
BACKGROUND:
Fusion imaging systems have proved to reduce radiation exposure mostly in hybrid rooms but reports with mobile C-arms are few. The aim of this study was to analyze the impact of the Endonaut navigation system on radiation exposure in endovascular aneurysm repair (EVAR) performed with mobile C-arms.METHODS:
All patients undergoing EVAR and/or iliac branched devices implantation between January 2016 and August 2022 were included. All procedures were performed with a mobile C-arm (Siemens Avantic or GE Elite until March 2018, Siemens Cios Alpha thereafter). The Endonaut navigation system has been used since January 2021. Two groups were, therefore, compared before (control group [CGr]) and after the use of Endonaut. Radiation data including Dose Area Product (DAP) values, Air Kerma (AK) and fluoroscopy time (FT) were collected retrospectively.RESULTS:
Overall, 153 patients were included CGr, n = 121; Endonaut group (EnGr), n = 32. No significant difference was found between the 2 groups regarding demographic data. DAP values were significantly lower in the EnGr (38 Gy cm2 ± 24) vs. the CGr (76 Gy cm2 ± 51) (P < 0.05) despite a significantly higher number of complex procedures such as iliac branched devices (P < 0.05). AK values were not significantly different between the EnGr and the CGr (196 mGy ±114 vs. 209 mGy ±138) as well as FT (33 minutes ±18 vs. 33 minutes ±16). Technical success was 97% (31/32) in the EnGr vs. 96% (116/121) in the CGr (P = 0.79). The volume of contrast media was significantly lower in the EnGr (94 cc ± 41) vs. the CGr (143 cc ± 66) (P < 0.05).CONCLUSIONS:
In this study, the use of the Endonaut angio-navigation system when performing EVAR with mobile C-arms led to a radiation dose reduction without compromising technical success or procedural time.
