A patient with non-traumatic intra-abdominal hemorrhage underwent damage control laparotomy following Zone 1 resuscitative endovascular balloon occlusion of the aorta (REBOA) for temporary hemostasis.
A 60-year-old female presented to an outside facility in hypertensive crisis and subsequently developed acute onset of abdominal pain, distension, and hypotension. Workup revealed possible bleeding in the lesser sac, and attempts at gastroduodenal artery angioembolization failed. On arrival at our center, she was hemodynamically unstable, requiring active transfusion. Temporary hemorrhage control was achieved using a resuscitative endovascular balloon deployed in Zone 1 of the aorta (origin of the subclavian artery to celiac). The patient was taken to the operating room for damage control laparotomy, visceral angiogram, and ligation of arterial hemorrhage at the head of the pancreas. She was hospitalized for two weeks and ultimately discharged home.
Noncompressible torso hemorrhage has a high incidence of mortality. The use of REBOA as an adjunct to sustain the circulation until definitive surgical or endovascular repair is achieved has been well documented in the trauma literature. While many studies have demonstrated improved survival rates with REBOA utilization in trauma patients, several reports have also promoted its usefulness in non-trauma patients. We present a case in which REBOA was used successfully to achieve temporary hemostasis for non-traumatic intra-abdominal hemorrhage.
hemorrhagic shock; non-trauma; resuscitative endovascular balloon occlusion of the aorta (REBOA)
A 60-year-old female presented in hypertensive crisis, with systolic blood pressure over 200mmHg, to an outside facility. While in the hospital, she developed severe pain, abdominal distension, and hypotension. Computerized tomography (CT) scan revealed intra-abdominal hemorrhage within the lesser sac near the head of the pancreas. She was transfused and underwent angiography by interventional radiology. No clear bleeding source was seen, but there was a blush in the lesser sac, and thus the gastroduodenal artery was coil embolized. Her hemodynamics remained labile, and she was transferred to our facility. At the outside facility, the patient received eight units of packed red blood cells (PRBC), seven units of fresh frozen plasma (FFP), and six platelets. The patient received an additional PRBC, FFP, and platelet in transport. She arrived in extremis, being actively transfused and receiving vasopressors. She received an additional five PRBCs, one FFP, and a Zone 1 REBOA was placed and inflated to 10mL (Figure 1). Systemic heparin was not given due to ongoing hemorrhage.
After REBOA inflation, the patient was able to maintain a mean arterial pressure >65mmHg, and her vasopressors were weaned off. She underwent an emergency visceral angiogram via a femoral approach from the contralateral side. Angiography revealed a ruptured pseudoaneurysm at a branch of the pancreaticoduodenal artery and a dislodgment of the previously placed gastroduodenal artery coils (Figure 2). Attempts at angioembolization were unsuccessful; therefore, an exploratory laparotomy was performed. Upon entry into the lesser sac, the REBOA was gradually released over a five-minute period as the surgical team controlled the bleeding by ligating arterial hemorrhage at the head of the pancreas. The REBOA was fully inflated for 58 minutes, and the REBOA catheter was removed after 110 minutes. The sheath was removed at the conclusion of the operation. The patient received ten PRBCs, seven FFP, two platelets, and a 450mL cell saver intraoperatively. She was initially managed with an open abdomen, and on postoperative day 2, the patient returned to the operating room for fascial closure. Postoperatively, the patient received one additional PRBC. There was very mild acute kidney injury with a peak creatinine of 1.1 (baseline 0.5) approximately 36 hours after REBOA placement. The remainder of her hospital course was uneventful.

Noncompressible torso hemorrhage (NCTH) is commonly encountered after trauma, and hemorrhagic shock is a leading cause of death in both military and civilian trauma.1,2 About 40% of deaths are due to bleeding or its complications, and hemorrhage is the most common cause of preventable death.3 Most of these deaths are due to NCTH, with estimates as high as 70% mortality following otherwise survivable injuries.1,4 The advantages of aortic occlusion in the setting of NCTH have been well documented.5‒8 Aortic occlusion during hemorrhagic shock results in increases in coronary blood flow, cardiac output, mean arterial pressure, carotid blood flow, and partial oxygen pressure of the brain.9
Early versions of REBOA for aortic occlusion and control of NCTH date back to the Korean War, yet due to poor outcomes and high complication rates, REBOA did not gain traction for many more years.10 However, there has been renewed interest in REBOA for the management of traumatic hemorrhage in the last decade. More modern versions of REBOA were initially used for ruptured abdominal aortic aneurysms (AAA). The utility and effectiveness of REBOA in the setting of ruptured AAA have been well-established, and thoracotomy for proximal aortic control in this setting is now rarely, if ever, utilized.9,11‒13
In recent years, there has been renewed interest in REBOA for trauma. Early results have shown that REBOA is a feasible method to control NCTH in patients in hemorrhagic shock and allows for more targeted aortic occlusion for pelvic, junctional, or extremity hemorrhage.9,14,15 Trauma patients who underwent REBOA have improved overall survival and fewer early deaths when compared to patients undergoing resuscitative thoracotomy(RT).9,16 Additionally, REBOA is far less invasive than RT, and complication rates have generally been low, especially with the introduction of an updated system with a smaller introducer sheath.17,18 Although limited data exist regarding complication rates for REBOA, prolonged ischemia followed by reperfusion can result in acute kidney injury, liver injury, intestinal ischemia, and spinal cord infarction.19 Availability of definitive hemorrhage control remains an important consideration since an increased length of time of REBOA balloon inflation is correlated with increased mortality and morbidity. Animal studies suggest Zone 1 REBOA is survivable for 60 minutes and Zone 3 for 90 minutes.20 In a systematic review of REBOA use, the median occlusion time for Zone 1 REBOA was 63 minutes (IQR 33-88 minutes) and 45 minutes (IQR 30-105 minutes) for Zone 3 REBOA.21 Severe complications of the lower extremities can also occur related to ischemia and vascular access complications, including pseudoaneurysm, hematoma, myonecrosis, and limb loss.22 One meta-analysis found that groin access complications for REBOA placement were approximately 4 to 5% among over 400 patients.23 Contraindications to REBOA include bleeding proximal to the left subclavian artery and signs of bleeding in the neck, as well as in the setting of major thoracic hemorrhage or pericardial tamponade.24
With the success of REBOA for traumatic NCTH, some have expanded REBOA use to non-traumatic NCTH. Approximately 2,000 deaths per year in the United States result from bleeding peptic ulcers, and hemorrhage accounts for one-quarter of maternal deaths globally. Thus, REBOA for non-traumatic NCTH represents an area for further investigation and potential reduction in mortality for these and other entities.25,26 Several reports have documented success when REBOA has been utilized in the setting of peripartum hemorrhage due to abnormal placentation or uterine rupture.27‒31 REBOA has also been used with mixed results for other non-traumatic hemorrhages, including gastrointestinal (GI) bleeding and rupture of visceral aneurysms.21,32 One systematic review did not find any episodes of mortality among studies reporting REBOA use for GI bleeding.21 In a recent multi-institutional study of patients with REBOA for non-traumatic hemorrhage, 43% had REBOA placed for GI bleed, and 3% had REBOA placed for visceral artery aneurysm rupture. The overall mortality in this study was 32%. However, it is not clear what proportion of patients with GI bleeding and visceral artery aneurysm died versus other indications for non-traumatic REBOA.33 In another small study of patients with REBOA for non-traumatic hemorrhage, approximately half of the cases were bleeding from a GI source or visceral artery aneurysm, and a similar mortality rate was reported.32
As for trauma, the use of REBOA for non-traumatic NCTH does not represent a solution but is useful for temporary hemostasis and stabilization. It must be a part of an organized strategy to obtain long-lasting hemorrhage control either by open surgical means or by using endovascular techniques. The temporary stabilization achieved by the use of REBOA prevents cardiovascular collapse and may extend the time available to investigate multiple hemostatic approaches. Our patient represents a case in which REBOA was successfully used to achieve temporary hemostasis and hemodynamic stabilization in the setting of non-traumatic abdominal hemorrhage.
Noncompressible torso hemorrhage has a high incidence of mortality. While REBOA as an adjunct to sustain the circulation until definitive surgical or endovascular repair is achieved has been well documented in the trauma literature, its use in non-traumatic hemorrhage is limited but evolving. We present a case in which REBOA was used successfully to achieve temporary hemostasis for non-traumatic intra-abdominal hemorrhage.
There may be a role for balloon occlusion of the aorta in non-traumatic noncompressible torso hemorrhage. Resuscitative endovascular balloon occlusion of the aorta has been used with success to stabilize patients with traumatic hemorrhagic shock. We present a case wherein this technique is successfully applied to a patient with non-traumatic abdominal hemorrhage.
