Placement of a balloon for resuscitative endovascular balloon occlusion of the aorta without fluoroscopic guidance in canine cadavers.

Objective: To determine whether a balloon for resuscitative endovascular balloon occlusion of the aorta (REBOA) could be accurately placed in the descending aorta between the left subclavian and celiac arteries (zone I) by using external anatomic landmarks in dogs.

Study Design: Cadaver study.

Sample Population: Fifteen canine cadavers of 3 weight categories (10-20, 20-30, and ≥ 30 kg).
