Abstract
Hemorrhage is the cause of death in 30-40% of severely injured patients due to trauma and the most frequent avoidable cause of death. In civilian emergency medical services, the majority of life-threatening hemorrhages are found in incompressible body regions (e.g. abdomen and pelvis). Resuscitative endovascular balloon occlusion of the aorta (REBOA) has therefore been discussed in recent years as a lifesaving procedure for temporary bleeding control in multiple trauma patients. Since August 2020 REBOA is implented in the treatment of seriously injured patients in the emergency department of the University Hospital of Bern. In this case series we report on our experiences in all seven patients in whom we performed this procedure during the first year.

On-site placement of resuscitative endovascular balloon occlusion of the aorta ( REBOA) in a hemorrhagic shock patient: A successful endeavor involving long-distance air transport. Am J Emerg Med 2022; 55:227.e1-227.e3.

Abstract
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is primarily utilized in traumatic non-compressible torso hemorrhage. We present a 49-year-old male with hemorrhagic shock necessitating on-site REBOA placement on an island 986 km away from the nearest critical care center. The patient experienced sudden pain in the right costal margin and visited the local clinic where computed tomography revealed a massive intra-abdominal hemorrhage and a renal artery aneurysm. An emergency care physician was deployed via fixed-wing aircraft who positioned the REBOA on-site in the thoracic aorta. Partial balloon inflation (partial REBOA) and intermittent inflation/deflation (intermittent REBOA) was repeated throughout the 5-h return flight. Despite prolonged REBOA placement, no safety issues or ischemic complications were documented and parent artery occlusion was subsequently performed via interventional radiology at our facility. The patient was later discharged home in a good state of health. On-site REBOA placement is not only applicable to trauma but also internal hemorrhaging due to non-traumatic causes. Partial and intermittent REBOA successfully stabilized circulation, prevented organ ischemia and facilitated long-distance patient transport in the present case.

Abstract
Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a lifesaving intervention for major truncal hemorrhage. Balloon-tipped arterial catheters are inserted via the femoral artery to create a temporary occlusion of the aorta, which minimizes the rate of internal bleeding until definitive surgery can be conducted. There is growing concern over the resultant hypoperfusion and potential damage to tissues and organs downstream of REBOA. To better understand the acute hemodynamic changes imposed by REBOA, we developed a three-dimensional computational fluid dynamic (CFD) model under normal, hemorrhage, and aortic occlusion conditions. The goal was to characterize the acute hemodynamic changes and identify regions within the aortic vascular tree susceptible to abnormal flow and shear stress. Methods: Hemodynamic data from established porcine hemorrhage models were used to build a CFD model. Swine underwent 20% controlled hemorrhage and were randomized to receive a full or partial aortic occlusion. Using CT scans, we generated a pig-specific aortic geometry and imposed physiologically relevant inlet flow and outlet pressure boundary conditions to match in vivo data. By assuming non-Newtonian fluid properties, pressure, velocity, and shear stresses were quantified over a cardiac cycle. Results: We observed a significant rise in blood pressure (∼147 mmHg) proximal to REBOA, which resulted in increased flow and shear stress within the ascending aorta. Specifically, we observed high levels of shear stress within the subclavian arteries (22.75 Pa). Alternatively, at the site of full REBOA, wall shear stress was low (0.04 ± 9.07E-4 Pa), but flow oscillations were high (oscillatory shear index of 0.31). Comparatively, partial REBOA elevated shear levels to 84.14 ± 19.50 Pa and reduced flow oscillations. Our numerical simulations were congruent within 5% of averaged porcine experimental data over a cardiac cycle. Conclusion: This CFD model is the first to our knowledge to quantify the acute hemodynamic changes imposed by REBOA. We identified areas of low shear stress near the site of occlusion and high shear stress in the subclavian arteries. Future studies are needed to determine the optimal design parameters of endovascular hemorrhage control devices that can minimize flow perturbations and areas of high shear.

Abstract
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is commonly used as an adjunct to resuscitation and bridge to definitive control of non-compressible torso hemorrhage in patients with hemorrhagic shock. It has also been performed for patients with neurogenic shock to support the central aortic pressure necessary for cerebral, coronary and spinal cord perfusion. Although volume replacement and vasopressors are the cornerstones of the management of neurogenic shock, we believe that a REBOA can be used as an adjunct in carefully selected cases to prevent prolonged hypotension and the risk of further anoxic spinal cord injury. This manuscript aims to propose a new damage control algorithmic approach to refractory neurogenic shock that includes the use of a REBOA in Zone 3. There are still unanswered questions on spinal cord perfusion and functional outcomes using a REBOA in Zone 3 in trauma patients with refractory neurogenic shock. However, we believe that its use in these case scenarios can be beneficial to the overall outcome of these patients.

Abstract
Thoracic vascular trauma is associated with high mortality and is the second most common cause of death in patients with trauma following head injuries. Less than 25% of patients with a thoracic vascular injury arrive alive to the hospital and more than 50% die within the first 24 hours. Thoracic trauma with the involvement of the great vessels is a surgical challenge due to the complex and restricted anatomy of these structures and its association with adjacent organ damage. This article aims to delineate the experience obtained in the surgical management of thoracic vascular injuries via the creation of a practical algorithm that includes basic principles of damage control surgery. We have been able to show that the early application of a resuscitative median sternotomy together with a zone 1 resuscitative endovascular balloon occlusion of the aorta (REBOA) in hemodynamically unstable patients with thoracic outlet vascular injuries improves survival by providing rapid stabilization of central aortic pressure and serving as a bridge to hemorrhage control. Damage control surgery principles should also be implemented when indicated, followed by definitive repair once the correction of the lethal diamond has been achieved. To this end, we have developed a six-step management algorithm that illustrates the surgical care of patients with thoracic outlet vascular injuries according to the American Association of the Surgery of Trauma (AAST) classification.

Changes in peripheral arterial blood pressure after resuscitative endovascular balloon occlusion of the aorta ( REBOA) in non-traumatic cardiac arrest patients. BMC Emerg Med 2021; 21:157. [PMID: 34911463 PMCID: PMC8672343 DOI: 10.1186/s12873-021-00551-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Accepted: 11/28/2021] [Indexed: 11/14/2022] Open
Abstract
Background Resuscitative endovascular balloon occlusion of the aorta (REBOA) may be an adjunct treatment to cardiopulmonary resuscitation (CPR). Aortic occlusion may increase aortic pressure and increase the coronary perfusion pressure and the cerebral blood flow. Peripheral arterial blood pressure is often measured during or after CPR, however, changes in peripheral blood pressure after aortic occlusion is insufficiently described. This study aimed to assess changes in peripheral arterial blood pressure after REBOA in patients with out of hospital cardiac arrest. Methods A prospective observational study performed at the helicopter emergency medical service in Trondheim (Norway). Eligible patients received REBOA as adjunct treatment to advanced cardiac life support. Peripheral invasive arterial blood pressure and end-tidal CO2 (EtCO2) was measured before and after aortic occlusion. Differences in arterial blood pressures and EtCO2 before and after occlusion was analysed with Wilcoxon Signed Rank test. Results Five patients were included to the study. The median REBOA procedural time was 11 min and median time from dispatch to aortic occlusion was 50 min. Two patients achieved return of spontaneous circulation. EtCO2 increased significantly 60 s after occlusion, by a mean of 1.16 kPa (p = 0.043). Before occlusion the arterial pressure in the compression phase were 43.2 (range 12–112) mmHg, the mean pressure 18.6 (range 4–27) mmHg and pressure in the relaxation phase 7.8 (range − 7 – 22) mmHg. After aortic occlusion the corresponding pressures were 114.8 (range 23–241) mmHg, 44.6 (range 15–87) mmHg and 14.8 (range 0–29) mmHg. The arterial pressures were significant different in the compression phase and as mean pressure (p = 0.043 and p = 0.043, respectively) and not significant in the relaxation phase (p = 0.223). Conclusion This study is, to our knowledge, the first to assess the peripheral invasive arterial blood pressure response to aortic occlusion during CPR in the pre-hospital setting. REBOA application during CPR is associated with a significantly increase in peripheral artery pressures. This likely indicates improved central aortic blood pressure and warrants studies with simultaneous peripheral and central blood pressure measurement during aortic occlusion. Trial registration The study is registered in ClinicalTrials.gov (NCT03534011).

Abstract
As care of the injured patient continues to evolve, new surgical technologies and new resuscitative therapies can change the algorithms that drive trauma care. In particular, the advent of resuscitative endovascular balloon occlusion of the aorta has changed the way trauma surgeons treat patients in extremis. The science of resuscitation continues to evolve, leading to controversy about the optimal administration of fluid and blood products. Laparoscopy has given additional tools to the trauma surgeon to potentially avoid exploratory laparotomy, and rib fracture fixation can be beneficial in the proper patient.

Abstract
BACKGROUND The effect of resuscitative endovascular balloon occlusion of aorta (REBOA) in lowering mortality rate compared to resuscitative thoracotomy (RT) is inconclusive. In this updated systematic review and meta-analysis, we determined the effectiveness of the two techniques in patients with noncompressible torso hemorrhage (NCTH). MATERIALS AND METHODS Online databases (PubMed, Embase, and MEDLINE) were searched until April 23, 2021, for original articles investigating the effect of REBOA on relevant outcomes (e.g., mortality in ED, mortality before discharge, in-hospital mortality, length of hospital stay and length of ICU stay) among NCTH patients in contrast to open aortic occlusion by RT. Data on baseline characteristics and endpoints were extracted. Review Manager version 5.4.1 and OpenMetaAnalyst were used for analyses. Risk ratios (RR) and the weighted mean differences (WMD) with corresponding 95% confidence intervals were calculated. RESULTS Eight studies were included having 3241 patients in total (REBOA: 1179 and RT: 2062). The pooled analysis demonstrated that compared to RT, mortality was significantly lower in the REBOA group in all settings: In emergency department (ED) (RR 0.63 [0.45, 0.87], P = 0.006, I2 = 81%), before discharge (RR= 0.86 [0.75, 0.98], P = 0.03, I2 = 93%), and in-hospital mortality (RR 0.80 [0.68, 0.95], P = 0.009, I2 = 85%). Similarly, the length of ICU stay was significantly lower in REBOA group (WMD = 0.50 [-0.48, 1.48], P = 0.32, I2 =97%). However, no significant differences were observed in the length of hospital stay (WMD = 0.0 [-0.26, 0.26] P = 1). CONCLUSIONS Our pooled analysis shows REBOA to be effective in reducing mortality among NCTH patients. However, due to limited studies, the positive findings should be viewed discreetly and call for further investigation.

Abstract
Traumatic injury remains the leading cause of death in patients 45 and younger. State of the art trauma care requires rapid interventions to provide hemodynamic support en route to definitive hemostasis. This article will review three critical elements in management of the bleeding trauma patient: blood products, resuscitative endovascular balloon occlusion of the aorta (REBOA), and the trauma hybrid operating room (THOR).

How to identify patients who require aortic vascular control in placenta accreta spectrum disorders? Am J Obstet Gynecol MFM 2021; 4:100498.

Abstract
BACKGROUND The placenta accreta spectrum disorder may lead to severe complications. Helpful interventions to prevent placenta accreta spectrum bleeding include vascular control procedures in the aorta or pelvic vessels. Although these procedures are related to lower intraoperative bleeding, they are associated with complications, so the possibility of selecting patients at highest risk of bleeding while avoiding vascular procedures for all cases is attractive. OBJECTIVE We describe an intraoperative staging protocol whose objective is to identify the need to use vascular control procedures in patients with placenta accreta spectrum. We also describe the results of its application in a placenta accreta spectrum referral hospital. STUDY DESIGN This descriptive, retrospective study included patients with suspected prenatal placenta accreta spectrum treated at a referral center for placenta accreta spectrum between April 2016 and June 2020. The use of the resuscitative endovascular balloon occlusion of the aorta allowed the prevention and treatment of excessive bleeding; its application was performed according to 3 approaches: (1) presurgical use in all placenta accreta spectrum patients (Group 1), (2) according to the prenatal placenta accreta spectrum topography (Group 2), and (3) according to the "intraoperative staging" (Group 3). In addition, the frequency of use of resuscitative endovascular balloon occlusion of the aorta and the clinical results in the management of placenta accreta spectrum were described in the 3 groups. RESULTS Seventy patients underwent surgery for a prenatal suspicion of placenta accreta spectrum. Of these, 16 underwent intraoperative staging (Group 3); in 20 cases, resuscitative endovascular balloon occlusion of the aorta was used based on the prenatal imaging topographic classification (Group 2), and in the remaining 34 patients (Group 1), it was always used before the laparotomy. The frequency of use of resuscitative endovascular balloon occlusion of the aorta was progressively lower in Groups 1 (32 patients, 94.1% of cases), 2 (11 patients, 75% of cases), and 3 (4 patients, 25% of cases). Similarly, resuscitative endovascular balloon occlusion of the aorta went from being applied predominantly before the laparotomy (all cases in Group 1) to being applied after intraoperative staging (all cases in Group 3). The percentage of endovascular devices applied but not used, decreased from 23.5% in Group 1 to 0% in Group 3. Complications related to the resuscitative endovascular balloon occlusion of the aorta were seen in 4 patients (2 women in Group 1, and 1 woman each in Groups 2 and 3). CONCLUSION The "intraoperative staging" of placenta accreta spectrum allows the optimization of the use of resuscitative endovascular balloon occlusion of the aorta, which decreases the frequency of its use without increasing the volume of blood loss.

Abstract
Patients presenting with hemodynamic instability associated with pelvic fractures continue to have very high mortality and surgeons continue to seek damage control strategies that may improve survival. Strategies usually require massive transfusion, immediate pelvic stabilization and another adjunctive maneuver's such as angioembolization or preperitoneal pelvic packing to prevent hemorrhagic death. One current intervention that has regained some popularity in lieu of resuscitative thoracotomy is the Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA). This requires some manner of femoral arterial access to insert a balloon into the aorta and increase central blood pressure (cardiac and cerebral perfusion) and control active pelvic bleeding. Based on several animal models and an increasing number of publications, many US level I trauma centers have now opted to use REBOA in carefully selected patients showing signs of near cardiac arrest from non-compressible torso hemorrhage. Description of the current advances in aortic occlusion using catheter-based technology in the setting of severe shock for non-compressible torso hemorrhage from pelvic ring fracture is the purpose of this report.

Abstract
OBJECTIVE To determine how many Level 1 and Level 2 trauma centres in Canada have implemented a resuscitative endovascular balloon occlusion of the aorta (REBOA) program, and to identify facilitators and barriers to successful implementation of REBOA programs. METHODS An electronic survey was developed and administered in November 2019 (updated in July 2021) via email to directors at all 32 Level 1 and Level 2 trauma centres across Canada, and to the medical director in PEI (no Level 1 or Level 2 capacity). Survey responses were supplemented by an online search in PubMed and the grey literature. Responses were analyzed using simple descriptive statistics including frequencies and proportions. RESULTS We received responses from directors at 22 sites (17 Level 1 trauma centres, 4 Level 2 trauma centres, PEI) for a response rate of 66.7%. There are 6 Level 1 trauma centres with REBOA programs; all were implemented between 2017 and 2019. One additional Level 1 trauma centre that did not respond was found to have a REBOA program; thus, 21.9% (7/32) of Canadian Level 1 and Level 2 trauma centres have an existing REBOA program. These programs are located in three provinces (British Columbia, Ontario, Quebec). Five other centres are planning on implementing a REBOA program in the next 2 years. The number of REBOA cases performed ranged from 0 to 30 (median 2). Factors contributing most to successful program implementation were having physician champions and patient populations with sufficient REBOA candidates, while cost and lack of expertise were the greatest barriers identified. CONCLUSION As of July 2021, 21.9% (7/32) of Canadian Level 1 and Level 2 trauma centres have a REBOA program. Physician champions and a patient population with sufficient numbers of REBOA candidates were the most important factors contributing to successful implementation of these programs.

Abstract
BACKGROUND Trauma is the leading cause of death in children. Resuscitative endovascular balloon occlusion of the aorta (REBOA) provides temporary hemorrhage control, but its potential benefit has not been assessed in children. We hypothesized that there are pediatric patients who may benefit from REBOA. METHODS Trauma patients <18 years old at a level 1 pediatric trauma center between 2009 and 2019 were queried for deaths, pre-hospital cardiac arrest, massive transfusion protocol activation, transfusion requirement, or hemorrhage control surgery. These patients defined the cohort of severely injured patients. From this cohort, patients with intraabdominal injuries for which REBOA may provide temporary hemorrhage control were identified, including solid organ injury necessitating intervention, vascular injury, or pelvic hemorrhage. RESULTS There were 239 severely injured patients out of 6538 pediatric traumas. Of these, 38 had REBOA-amenable injuries (15.9%) with 34.2% mortality, accounting for 10.2% of all pediatric trauma deaths at one center. Eleven patients with REBOA-amenable injuries had TBI (28.9%). Patients with REBOA-amenable injuries represented 0.6% of all pediatric traumas. CONCLUSION Nearly 20% of severely injured pediatric patients could potentially benefit from REBOA. The overall proportion of pediatric patients with REBOA-amenable injuries is similar to adult studies. TYPE OF STUDY Retrospective comparative study. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVES To perform a province-wide evaluation of adult major traumas and determine the proportion of patients who met clinical and/or anatomical criteria for resuscitative endovascular balloon occlusion of the aorta (REBOA). METHODS This is a retrospective analysis of all major trauma patients (age > 16) presenting to the sole adult level 1 trauma centre in Nova Scotia over a 5-year period (2012-2017). Data were collected from the Nova Scotia Trauma Registry and medical charts. We identified potential REBOA candidates using either: (1) clinical criteria (primary survey, Focused Assessment with Sonography for Trauma, pelvic/chest X-ray); or (2) anatomical criteria (ICD-10-CA codes). Potential candidates with persistent hypotension were considered true REBOA candidates. RESULTS Overall 2885 patients were included in the analysis, of whom 248 (8.6%) patients were in shock (including 106 transfer patients) and had their charts reviewed. A total of 137 patients met clinical criteria for REBOA; 44 (1.5%) had persistent hypotension 10-20 min into resuscitation and were considered true REBOA candidates. There were 59 patients who met anatomical criteria for REBOA, of whom 15 (0.5%) patients had persistent hypotension and were true REBOA candidates. The 15 REBOA candidates based on anatomical criteria also met clinical criteria for REBOA. CONCLUSIONS In this registry-based retrospective analysis, 1.5% of adult major trauma patients Nova Scotia were REBOA candidates based on resuscitative clinical presentation, while 0.5% were candidates based on post hoc anatomical injury patterns. Our findings suggest that using clinical findings and bedside imaging modalities as criteria may overestimate the number of candidates for REBOA.

Abstract
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.

Abstract
The spleen is one of the most commonly injured solid organs of the abdominal cavity and an early diagnosis can reduce the associated mortality. Over the past couple of decades, management of splenic injuries has evolved to a prefered non-operative approach even in severely injured cases. However, the optimal surgical management of splenic trauma in severely injured patients remains controversial. This article aims to present an algorithm for the management of splenic trauma in severely injured patients, that includes basic principles of damage control surgery and is based on the experience obtained by the Trauma and Emergency Surgery Group (CTE) of Cali, Colombia. The choice between a conservative or a surgical approach depends on the hemodynamic status of the patient. In hemodynamically stable patients, a computed tomography angiogram should be performed to determine if non-operative management is feasible and if angioembolization is required. While hemodynamically unstable patients should be transferred immediately to the operating room for damage control surgery, which includes splenic packing and placement of a negative pressure dressing, followed by angiography with embolization of any ongoing arterial bleeding. It is our recommendation that both damage control principles and emerging endovascular technologies should be applied to achieve splenic salvage when possible. However, if surgical bleeding persists a splenectomy may be required as a definitive lifesaving maneuver.

Abstract
Approximately 1% of all patients are admitted to an emergency room for upper gastrointestinal hemorrhage. Differential diagnostics reveal an aortoesophageal fistula (AEF) as the cause of the bleeding in very few cases. Despite increasing means of diagnostics and treatment, mortality is high in patients with AEF even under maximum medical care. These are often fulminant situations with fatal outcome for the patient. We report a case that supports this observation described from previous cases and give a closer look at this rare emergency situation. A 54-year-old patient was taken to a maximum care hospital with the clinical diagnosis of upper gastrointestinal bleeding after receiving emergency medical treatment. The source of bleeding was quickly identified as an AEF following lobectomy for bronchial cancer. Despite maximum interventional intensive treatment, the patient died a few hours after hospital admission in hemorrhagic shock due to fulminant hemorrhage from the fistula.

Abstract
Penetrating torso trauma is the second leading cause of death following head injury. Traffic accidents, falls and overall blunt trauma are the most common mechanism of injuries in developed countries; whereas, penetrating trauma which includes gunshot and stabs wounds is more prevalent in developing countries due to ongoing violence and social unrest. Penetrating chest and abdominal trauma have high mortality rates at the scene of the incident when important structures such as the heart, great vessels, or liver are involved. Current controversies surround the optimal surgical approach of these cases including the use of an endovascular device such as the Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) and the timing of additional imaging aids. This article aims to shed light on this subject based on the experience earned during the past 30 years in trauma critical care management of the severely injured patient. We have found that prioritizing the fact that the patient is hemodynamically unstable and obtaining early open or endovascular occlusion of the aorta to gain ground on avoiding the development of the lethal diamond is of utmost importance. Damage control surgery starts with choosing the right surgery of the right cavity in the right patient. For this purpose, we present a practical and simple guide on how to perform the surgical approach to penetrating torso trauma in a hemodynamically unstable patient.

Abstract
INTRODUCTION To analyze our experience to quantify potential need for resuscitative endovascular balloon occlusion of the aorta (REBOA). METHODS Retrospective review of patients over a three-year period who presented as a trauma with hemorrhagic shock. Patients were divided into two groups: REBOA Candidate vs. Non-candidates. Injuries, outcomes, and interventions were compared. RESULTS Of 7643 trauma activations, only 37 (0.44%) fit inclusion criteria, of which 16 met criteria for candidacy for potential REBOA placement. The groups did not differ in terms of injury severity, physiology, age, timing of intervention, nor massive transfusion. Survival was linked to TRISS (p = 0.01) and Emergency Room Thoracotomy (p = 0.002). Of Candidates, 8 (50%) had injuries that could have benefited from REBOA, while 7 (44%) had injuries that could be associated with potential harm. DISCUSSION The volume of patients who would potentially benefit from REBOA appears to be small and does not appear to support system wide adoption in the studied region. LEVEL OF EVIDENCE IV.

Abstract
OBJECTIVE The aim of this study was to compare two vascular control options for blood loss prevention and hysterectomy during cesarean delivery (CD2): endovascular balloon occlusion of the aorta (REBOA3) and open bilateral common iliac artery occlusion (CIAO4) in women with extensive placenta accreta spectrum (PAS5). STUDY DESIGN This was retrospective comparison of cases of PAS using either CIAO (October 2017 through October 2018) or REBOA (November 2018 through November 2019) to prevent pathologic hemorrhage during scheduled CD. Women with confirmed placenta increta/percreta underwent either CD then intraoperative post-delivery, pre-hysterectomy open vascular control of both CIA6 (CIAO group) or pre-operative, ultrasound-guided, fluoroscopy-free REBOA followed by standard CD and balloon inflation after fetal delivery (REBOA group). Intraoperative blood loss, transfusion volumes, surgical time, blood pressure, maternal and neonatal outcomes, hospitalization length and postoperative complications were compared. RESULTS The REBOA and CIAO groups included 12 and 16 women, respectively, with similar median age of 35 years and gestational age of 34-35 weeks. All REBOA catheters were successfully placed into aortic zone three under ultrasound guidance. The quantitated median intraoperative blood loss was significantly lower for the REBOA group, (541 [IQR 300-750] mL) compared to the CIAO group (3331 [IQR 1150-4750] mL (P = 0.001). As a result, the total volume of fluid and blood replacement therapy was significantly lower in the REBOA group (P < 0.05). Median surgical time in the REBOA group was less than half as long: 76 [IQR 64-89] minutes compared to 168 [IQR 90-222] minutes in the CIAO group (P = 0.001). None of the women with REBOA required hysterectomy, while 8/16 women in the CIAO group did (P = 0.008). Furthermore, the post-anesthesia recovery and hospital discharge times in the REBOA-group were shorter (P < 0.05). One thromboembolic complication occurred in each group. The only REBOA-associated complication was non-occlusive femoral artery thrombosis, with no surgical management required. No maternal or neonatal deaths occurred in either group. CONCLUSION Fluoroscopy-free REBOA for women with PAS is associated with improved vascular control, perioperative blood loss, the need for transfusion and hysterectomy and reduces surgical time when compared to bilateral CIAO.

Abstract
Hepatic artery pseudoaneurysm (HAP) is a rare, highly morbid and frequently fatal complication of liver transplantation. Most are a mycotic mediated weakness of the arterial wall, with associated bacterial or fungal infection of ascitic fluid. As it is usually asymptomatic prior to rupture, the majority present in acute hemorrhagic shock and dire extremis. Resuscitative endovascular balloon occlusion (REBOA) was initially developed for the management of noncompressible hemorrhagic shock in trauma; however, remains underutilized and understudied in the non-trauma setting. We present the case of a mycotic hepatic artery pseudoaneurysm rupture due to Streptococcus constellatus and Klebsiella pneumoniae post directed donor orthoptic liver transplant, in which REBOA was employed in the setting of impending exsanguination as a bridge to definitive surgical intervention. Although this patient passed away of multiorgan system failure prior to re-transplant, this case demonstrates the importance of a heightened suspicion of this devastating complication, especially in the setting of bilioenteric reconstruction and perihepatic fluid collection, as well as the benefit of utilizing resuscitative techniques such as REBOA prior to definitive surgical or endovascular therapy to mitigate the high morbidity and mortality of this condition.

Abstract
INTRODUCTION The effectiveness of resuscitative endovascular balloon occlusion of the aorta (REBOA) in controlling pelvic bleeding has been reported with increasing frequency during surgical management of placenta accreta spectrum (PAS). The deployment of REBOA may lead to significant variations in vital signs requiring special care by anesthesiology during surgery. These modifications of blood pressure by REBOA in PAS patients have not been accurately documented. We report the changes in blood pressure that occur when the aorta is occluded and then released in patients with PAS. METHODOLOGY This prospective, observational study includes 10 patients with preoperative PAS suspicion who underwent prophylactic REBOA device insertion between April 2018 and October 2019. REBOA procedural-related data and blood pressure fluctuations under invasive monitoring before and after inflation and deflation were recorded in the operating room. RESULTS After prophylactic REBOA deployment in zone 3 of the aorta in PAS patients, we observed a transitory increase in blood pressure (median increase of 22.5 mmHg in SBP and 9.5 mmHg in DBP), which reached severe hypertension (SBP >160 mmHg) in 50% of patients. All patients presented a decrease in blood pressure after the removal of the aortic occlusion (median decrease of 23 mmHg in SBP and 10.5 mmHg in DBP), and 50% (five patients) required the administration of vasopressor drugs. CONCLUSION Immediately after aortic occlusion is applied in zone 3 in PAS patients and after the occlusion is removed, significant hemodynamic changes occur, which often lead to therapeutic interventions.

The majority of major amputations after resuscitative endovascular balloon occlusion of the aorta are associated with preadmission trauma. J Vasc Surg 2021; 74:467-476.e4.

Abstract
OBJECTIVE Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a potentially life-saving intervention. However, recent reports of associations with limb loss and mortality have called its safety into question. We aimed to evaluate patient and hospital characteristics associated with major amputation and in-hospital mortality among patients undergoing REBOA for trauma. METHODS The National Trauma Data Bank (2015-2017) was queried for patients presenting to trauma centers and treated with REBOA. We included REBOA performed on hospital day 1 in patients who survived 6 or more hours from presentation. Univariable and multivariable analyses evaluated associations with major amputation and in-hospital mortality. RESULTS A total of 316 patients underwent REBOA and survived in the acute period after presentation. Overall, mean age was 45 ± 20 years and the majority were male (73%) and White (56%). Most patients presented to level I trauma centers (72%) after blunt injuries (79%) with an average Injury Severity Score (ISS) of 31 ± 15, indicating major trauma. In 15 patients (5%), there were 18 major amputations-7 above knee and 11 below knee. A subgroup of 11 amputations were either traumatic amputations (73%) or mangled limbs requiring amputation within 24 hours (27%). Of the remaining amputations, 71% were associated with ipsilateral vascular or orthopedic lower extremity injuries of serious to severe Abbreviated Injury Scale severity. Comparing patients with amputations with those without amputations, there were no significant differences in patient demographics, comorbidities, or hospital characteristics. During hospitalization, patients requiring amputation more frequently received open peripheral vascular interventions (40% vs 10%; P = .002), underwent similar numbers of endovascular interventions (6.7% vs 4.7%; P = .5), and more often developed compartment syndrome (13% vs 2%; P = .04). Overall, there were 110 deaths (35%). The major amputation prevalence was similar between patients who died vs those who survived (3.6% vs 5.3%; P = .5). In multivariable analysis, prehospital cardiac arrest (odds ratio [OR], 8.47; 95% confidence interval [CI], 1.47-48.66; P = .02), penetrating vs blunt trauma (OR, 5.5; 95% CI, 1.05-28.82; P = .04), decreased Glasgow Coma Scale score (OR, 1.18; 95% CI, 1.05-1.32; P = .01), older age (OR, 1.06; 95% CI, 1.03-1.10; P < .001), and increased Injury Severity Score (OR, 1.05; 95% CI, 1.0-1.1; P = .03) were associated with higher mortality. CONCLUSIONS The majority of major amputations in patients undergoing REBOA were secondary to the initial traumatic mechanism. Injury type and severity, as well as initial hemodynamic derangements, are associated with mortality after REBOA. Despite concerns about prohibitive limb complications of REBOA, baseline injuries seem to be the primary cause of limb loss, but further prospective analysis is needed.

Abstract
BACKGROUND The aim of this study is to evaluate the feasibility of en-route resuscitative endovascular balloon occlusion of the aorta (REBOA) on board of a helicopter. METHODS Six sedated male sheep (weighing 42-54 kg) underwent a controlled hemorrhage until the systolic blood pressure (BP) dropped to <90 mmHg, and were placed into a low capacity Eurocopter AS-350 (France). During the 30-minutes normal flight, every animal underwent blind (left side) and ultrasound-guided (US) (right side) vascular access (VA) to the femoral artery followed by REBOA: the first catheter (Rescue balloon, Japan) - into Zone I, the second one (MIT, Russia) - Zone III. In case of blind VA failure, an alternate US-puncture was attempted. Six experienced flight anesthetists were enrolled into the study. Vascular access and REBOA catheter placement (confirmed by X-Ray later) success rate and timing were recorded. RESULTS Among six blind punctures one was successful, 2/6 - were into the vein, 3/6 - completely failed and switched to US-punctures (making total number of US-punctures nine). Eight out of nine US-punctures were successful. However, correct wire insertion and sheath placement was performed in 1/6 animal in the 'blind' group and only in 6/9 animals in the 'US' group. It took a median of 65 seconds (range 5-260) for US-puncture and a median of 4 minutes to get the sheath in. Among the 9 VAs, there were 2 REBOA failures (1 ruptured balloon [MIT] and 1 mistaken vena cava placement primarily recognized by a sudden drop of BP and later confirmed by X-Ray). Five out of seven balloons were placed in a desired intra-aortic position: 4/5 in Zone I and 1/2 - in Zone III. A median time for a successful REBOA procedure was 5.0 (range 2.5-10.0) minutes (1 min after sheath placement). CONCLUSION Our study demonstrates the potential feasibility of the en-route REBOA which can be performed within 5 minutes. Ultrasound-guidance is critically important to achieve en-route VA.
