Abstract

Background Resuscitative endovascular balloon occlusion of the aorta (REBOA) should be safely placed at zone 1 or 3, depending on the location of the hemorrhage. Ideally, REBOA placement should be confirmed via fluoroscopy, but it is not commonly available for trauma bays. This study aimed to evaluate the accuracy of REBOA placement using the external measurement method in a Japanese trauma center. Methods A retrospective review identified all trauma patients who underwent REBOA and were admitted to our trauma center from 2008 to 2018. Patient characteristics, REBOA placement accuracy, and complications according to target zones 1 and 3 were reviewed. Results During the study period, 38 patients met our inclusion criteria. The in-hospital mortality rate was 57.9%. REBOA was mainly used for bleeding from the abdominal (44.7%) and pelvic (36.8%) regions. Of these, 30 patients (78.9%) underwent REBOA for target zone 1, and 8 patients (21.1%) underwent REBOA for target zone 3. The proportion of abdominal bleeding source in the target zone 1 group was greater than that in the target zone 3 group (56.7% vs. 0%). Overall, the proportion of REBOA placement was 76.3% in zone 1, 21.1% in zone 2, and 2.6% in zone 3. The total REBOA placement accuracy was 71.1%. At each target zone, the REBOA placement accuracy for target zone 3 was significantly lower than that for target zone 1 (12.5% vs. 86.7%, p<0.001). No significant associations between non-target zone placement and patient characteristics, complications, or mortality were found. Conclusions The REBOA placement accuracy for target zone 3 was low, and zone 2 placement accounted for 21.1% of the total, but no complications and mortalities related to non-target zone placement occurred. Further external validation study is warranted. Level of evidence Level IV.
