Using computed tomography to evaluate anatomic landmarks in taiwanese trauma patients for insertion of resuscitative endovascular balloon occlusion of the aorta: A retrospective cohort study.

For zone 1 occlusions, a range of 44-48 cm insertion length cross-referenced with the mid-sternal landmark is recommended. For zone 3 occlusions, using the umbilicus as a guide with the distance between the umbilicus, xiphoid process, and pubic ramus provided the highest accuracy.
