RESUMEN
BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a novel method of controlling subdiaphragmatic hemorrhage while improving hemodynamic stability. This procedure achieves many of the goals of resuscitative thoracotomy (RT), but is less invasive. Here, we present the initial experience with REBOA at a level 1 academic trauma center. STUDY DESIGN: We performed a retrospective review. Orientation of surgeons and residents to REBOA was accomplished by an educational program including a hands-on simulation session (1.5 hours). Surgeons were not required to attend an external training course. Operating room personnel were oriented with a slide presentation. Initially, a 12-Fr introducer and aortic occlusion balloon were used. Subsequently, a 7-Fr device was used. All REBOAs were performed in a dedicated hybrid operating room. Resuscitative thoracotomy was performed in the trauma bays and operating room. RESULTS: During a 21-month period (June 2015 to March 2017), 16 patients (Injury Severity Score [ISS] 38.6 ± 22.3, Glasgow Coma Scale [GCS] 8.9 ± 5.9, lactate 4.91 ± 3.26 mmol/L) had REBOA placed. All patients were hemodynamically unstable (systolic blood pressure 96.5 ± 9.3 mmHg) due to hemorrhage. Preoperative hemoglobin ranged from 5 to 14.4 mg/dL. Etiology of hemorrhage was blunt trauma (n = 11), penetrating injury (n = 2), and nontraumatic mechanisms (n = 3). After REBOA, hemodynamic status improved in 10 of 16 patients. Fourteen patients survived the initial operative intervention and 6 survived 30 days; REBOA was successfully performed in all patients. One survivor developed a common femoral pseudoanuerysm. Survival for RT (ISS 31.3 ± 11.25) during same period was 0%. CONCLUSIONS: Resuscitative endovascular balloon occlusion of the aorta is an effective method of improving hemodynamic status in patients with sub-diaphragmatic hemorrhage. Extensive training is not required to implement a REBOA program, and REBOA is a useful technique for trauma surgeons.
