Background This work aims to evaluate the impact of hybrid rooms and their advanced tools on the accuracy of proximal deployment of infrarenal bifurcated endograft (EVAR). Methods A retrospective single center analysis was conducted between January 2015 and March 2019 including consecutive patients that underwent EVAR. Groups were defined whether the procedure was performed in a hybrid operating room (HOR group) or using a mobile 2D fluoroscopic imaging system (non-HOR group). The accuracy of the proximal deployment was estimated by the distance (mm) between the bottom of the lowest renal artery (LwRA) origin and the endograft radiopaque markers parallax (LwRA/EDG distance) after curvilinear reconstruction. The impact of HOR on the LwRA/EDG distance was investigated using a multiple linear regression model. A composite “proximal neck”-related complications event was studied (Cox models). Results Overall, 93 patients (87 %male, median age 73 years) were included with 49 in the HOR group and 44 in the non-HOR group. Preoperative CTA analysis of the proximal neck exhibited similar median length, but different median aortic diameter (P = 0.012) and median beta angulation (P = 0.027) between groups. The median LwRA/EDG distance was shorter in the HOR group (multivariate model, P = 0.022). No difference in “proximal neck”-related complications was evidenced between the HOR and non-HOR groups (univariate analysis, P = 0.620). Median follow-up time was respectively 25 [14–28] and 36 months [23–44] in the HOR group and in the non-HOR group (P < 0.001). Conclusion HOR offer more accurate proximal deployment of infrarenal endografts, with however no difference in “proximal neck”-related complications between groups.
