Abstract

Purpose: Evaluate the impact of hybrid operating room (HOR) guidance on the long-term clinical outcomes following fenestrated and branched endovascular repair (F-BEVAR) for complex aortic aneurysms. Materials and Methods: Prospectively collected registry data were retrospectively analyzed to compare the procedural, short- and long-term outcomes of consecutive F-BEVAR performed from January 2010 to December 2014 under standard mobile C-arm versus hybrid room guidance in a high-volume aortic center. Results: A total of 262 consecutive patients, including 133 patients treated with a mobile C-arm equipped operating room and 129 with a HOR guidance, were enrolled in this study. Patient radiation exposure and contrast media volume were significantly reduced in the HOR group. Short-term clinical outcomes were improved despite higher case complexity in the HOR group, with no statistical significance. At a median follow-up of 63.3 months (Q1 33.4, Q3 75.9) in the C-arm group, and 44.9 months (Q1 25.1, Q3 53.5, p=0.53) in the HOR group, there was no statistically significant difference in terms of target vessel occlusion and limb occlusion. When the endograft involved 3 or more fenestrations and/or branches (complex F-BEVAR), graft instability (36% vs 25%, p=0.035), reintervention on target vessels (20% vs 11%, p=0.019) and total reintervention rates (24% vs 15%, p=0.032) were significantly reduced in the HOR group. The multivariable Cox regression analysis did not show statistically significant differences for long-term death and aortic-related death between the 2 groups. Conclusion: Our study suggests that better long-term clinical outcomes could be observed when performing complex F-BEVAR in the latest generation HOR.
