REBOA - have mortality and complications changedover time? : - A comparison between years 2011-2015 and 2016-2020
Abstract: Introduction Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is an invasivetechnique aimed at stabilizing hemodynamically unstable patients. The technique is underconstant development and in 2016 a new REBOA balloon requiring a smaller sized sheathwas introduced aiming to decrease complications and mortality. Studies show contradictoryfindings concerning outcome and complications of REBOA. Aim To investigate if survival and complications of patients treated with REBOA changed overtime by comparing two time periods, 2011-2015 and 2016-2020. Methods This was a retrospective registry study. Data was extracted from the Aortic Balloon Occlusion(ABO) trauma registry and 217 patients were included in the study. Patients were divided intotwo calendar periods, an early period (2011-2015) and a late period (2016-2020). Results Mortality at the emergency department was 24 % in the early period compared to 9 % in thelate period (p= 0.018). Mortality within 24 hours was reported in 40 % in the early period and36 % in the late period. In the early period, mortality within 30 days was 59 % and 36 % inthe late period. Access related complications such as extremity ischemia was reported in 1 %in the early period and 12 % in the late period (p = 0.001). Conclusion Early mortality at the emergency department has decreased over time. Access relatedcomplications were present in both the early and late period but extremity ischemia was morecommon in the late period.
