A 53-year-old male pedestrian was hit by a car and arrived at our hospital with a blunt abdominal injury and hemorrhagic shock. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) was performed in a timely fashion using the open groin technique in the emergency room. The procedure resulted in rapid improvement of hemodynamic status while the bleeding source was controlled. Recently, REBOA is a proper adjunctive procedure in major non-compressible torso hemorrhage patients. The procedure requires a portable X-ray or fluoroscopic machine in the ER to confirm the balloon's position. This method has likely limited the use of REBOA in developing countries. The procedure with open groin technique, using anatomical landmarks and physiologic change to confirm the position of the balloon, has been developed to address these concerns. Here we report on the treatment's success with this technique and believe that it can benefit trauma patient care.
