RESUMO
BACKGROUND: Use of resuscitative endovascular balloon occlusion of the aorta (REBOA) for temporary hemorrhage control in severe non-compressible torso trauma remains controversial, with limited data on patient selection and outcomes. This study aims to analyze the nationwide trends of its use in the emergency department (EDs). METHODS: A retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program (ACS-TQIP) from 2017 to 2022 was performed, focusing on REBOA placements in EDs. RESULTS: The analysis included 3398 REBOA procedures. Majority patients were male (76 â%) with a median age of 40 years (27-58) and injury severity score of 20 (20-41). The most common mechanism was collision (64 â%), with emergency surgeries most frequently performed for pelvic trauma (14 â%). Level 1 trauma centers performed 82 â% of these procedures, with consistent low annual utilization (<200 facilities). Survival rates were 85 â% at 1-h post-placement, decreasing significantly to 42 â% by discharge. CONCLUSIONS: REBOA usage in remains limited but steady, primarily occurring at level 1 trauma center EDs. While short-term survival rates are favorable, they drop significantly by the time of discharge.
RESUMO
As of 2020, penetrating injuries became the leading cause of death among children and adolescents ages 1-19 in the United States. For the patients who initially survive and receive advanced medical care, vascular injuries are a significant cause of morbidity and additionally trigger notable trauma team angst. Moreover, penetrating injuries can lead to life-threatening hemorrhage and/or limb-threatening ischemia if not addressed promptly. Vascular injury management demands timely and unique expertise, particularly for pediatric patients. As the frequency of vascular injuries requiring operative management increases, it becomes clear that an ad hoc approach is not ideal. An integrated team would provide the best approach for rapid hemorrhage control and revascularization, but the structure of vascular response teams at children's hospitals is highly variable. In part 1 of this review, we will evaluate the scope and extent of the epidemic of traumatic vascular injuries in pediatric patients, review current evidence and outcomes, discuss various challenges and advantages of different team structures, and outline potential outcome targets and pediatric vascular trauma response solutions. LEVEL OF EVIDENCE: n/a.
RESUMO
As of 2020, penetrating injuries became the leading cause of death among children and adolescents ages 1-19 in the United States. For those patients who survive and receive advanced medical care, vascular injuries are a significant cause of morbidity and trigger notable trauma team angst. Moreover, penetrating injuries can lead to life-threatening hemorrhage and/or limb-threatening ischemia if not addressed promptly. Vascular injury management demands timely and unique expertise, particularly for pediatric patients. In part 1 of this review, we discussed the scope and extent of the epidemic of traumatic vascular injuries in pediatric patients, reviewed current evidence and outcomes, discussed various challenges and advantages of a myriad of existing team structures, and outlined potential outcome targets and solutions. However, in order to optimize care for pediatric vascular trauma, we must also understand the fundamental best practice principles, surgical options and approaches, medical management, and recommendations for ongoing, outpatient follow-up. In part 2, we will address the best evidence, combined with expert consensus, regarding strategies for diagnosing, managing, and ongoing follow-up of vascular trauma, with particular focus on the nuances that define the unique approaches to pediatric patients.

RESUMO
BACKGROUND: The revised American Association for the Surgery of Trauma (AAST) organ injury scale (OIS) for splenic injury incorporates radiologic features but the implications of this are unknown. We hypothesized that the revised AAST-OIS would better predict outcomes. METHODS: Patients with a blunt splenic injury admitted to a Level I trauma center were reviewed from 2016 to 2021. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for splenectomy were calculated for high-grade injuries (AAST-OIS grades IV-V) using both schemas. RESULTS: Of the 852 patients analyzed, 48.5% were observed, 24.6% were embolized, and the remaining underwent operative intervention. The median AAST-OIS increased from II to III (p â< â0.01). Sensitivity (38.0% vs. 73.7%) and NPV (80.9% vs. 88.2%) for splenectomy increased for high-grade injuries but specificity (93.5% vs 70.1%) and PPV (67.5% vs 46.7%) decreased. CONCLUSION: The revised AAST-OIS better predicted splenic salvage but is less accurate at predicting need for splenectomy.
RESUMO
INTRODUCTION: Brachial artery trauma is a rare but potentially devastating injury. There is little data regarding risk factors for reintervention and amputation prevention in this population, as well as anticoagulant (AC) and antiplatelet (AP) regimens and outcomes after discharge in trauma patients with vascular injuries requiring repair. This study aims to identify in-hospital risk factors for reintervention and amputation and stratify outcomes of follow-up by discharge AC or AP regimen. METHODS: The AAST Prospective Observational Vascular Injury Trial database was queried for all patients who underwent traumatic brachial arterial repair from 2013 to 2022. Patients were evaluated by need for reintervention, amputation, and outcomes at follow-up by AC or AP regimen. RESULTS: Three hundred and eleven patients required brachial repair, 28 (9%) required reoperation, and 8 (2.6%) required amputation. High injury severity score and an increased number of packed red blood cells and platelets showed a significant increase for reoperation and amputation. Damage control and shunt use were significant for the need to reoperate. Seventy-four percent (221/298) of patients were discharged with postoperative AC or AP regimens. There was no significant difference of short-term follow-up by type of AC or AP regimen. CONCLUSIONS: Damage control and temporary shunt may lead to additional operations but not an increase in amputations. However, anticoagulation intraoperatively and postoperatively does not appear to play a significant role in reducing reintervention. It also suggests that there is no increase in short-term follow-up complications with or without AC or AP therapy.

INTRODUCTION: As part of New Deal era federal housing policy, the Home Owners Loan Corporation (HOLC) developed maps grading US neighborhoods by perceived financial security. Neighborhoods with high concentrations of racial and ethnic minorities were deemed financially unstable and denied federal investment, a practice colloquially known as redlining. The aim of this study was to assess the association of historical redlining within Austin, Texas to spatial patterns of penetrating traumatic injury. METHODS: Retrospective cross sectional study utilizing data from violent penetrating trauma admissions between January 1, 2014 - December 31, 2021, at the single Level 1 trauma center in Austin, Texas. Using ArcGIS, addresses where the injury took place were geocoded and spatial joining was used to match them to their corresponding census tract, for which 1935 HOLC financial designations are classified as: "Hazardous", "Definitely Declining", "Still Desirable", "Best", or "Non HOLC Graded". Tracts with designations of "Hazardous" and "Definitely Declining" were categorized as Redlined. The adjusted incidence rate ratio comparing rates of penetrating trauma among historically Redlined vs. Not Redlined and Not Graded census tracts was calculated. RESULTS: 1,404 violent penetrating trauma admissions were identified for the study period, of which 920 occurred within the county of interest. Among these, 5% occurred in census tracts that were Not Redlined, 13% occurred in Redlined tracts, and 82% occurred in non HOLC graded tracts. When adjusting for differences in current census tract demographics and social vulnerability, historically Redlined areas experienced a higher rate of penetrating traumatic injury (Not Redlined IRR = 0.42, 95% CI 0.19-0.94, p = 0.03; Not Graded IRR = 0.15, 95% CI 0.07-0.29, p < 0.001). CONCLUSIONS: Neighborhoods unfavorably classified by HOLC in 1935 continue to experience a higher incidence rate of violent penetrating trauma today. These results underscore the persistent impacts of structural racism and of historical residential segregation policies on exposure to trauma. LEVEL OF EVIDENCE: Level IV, Prognostic and Epidemiological.
RESUMO
Traumatic injury leading to arterial damage has traditionally been repaired using autologous vein graft from the contralateral limb. This often requires a secondary surgical site and the potential of prolonged operative time for patients. We sought to assess the use of ipsilateral vs contralateral vein grafts in patients who experienced traumatic extremity vascular injury. A multicenter database was queried to identify arterial injuries requiring operative intervention with vein grafting. The primary outcome of interest was need for operative reintervention. Secondary outcomes included risk of thrombosis, infection, and intensive care unit length of stay. 358 patients (320 contralateral and 38 ipsilateral) were included in the analysis. The ipsilateral vein cohort did not display a statistically significant decrease in need for reoperation when compared to the contralateral group (11% vs 23%; OR 0.41, 95% CI -0.07-1.3; P = .14). Contralateral repair was associated with longer median intensive care unit (ICU) LOS (4.3 vs 3.1 days; P < .01).

BACKGROUND: The optimal management of blunt thoracic aortic injury (BTAI) remains controversial, with experienced centers offering therapy ranging from medical management to TEVAR. We investigated the utility of a machine learning (ML) algorithm to develop a prognostic model of risk factors on mortality in patients with BTAI. METHODS: The Aortic Trauma Foundation registry was utilized to examine demographics, injury characteristics, management and outcomes of patients with BTAI. A STREAMLINE (A Simple, Transparent, End-To-End Automated Machine Learning Pipeline Facilitating Data Analysis and Algorithm Comparison) model as well as logistic regression (LR) analysis with imputation using chained equations was developed and compared. RESULTS: From a total of 1018 patients in the registry, 702 patients were included in the final analysis. Of the 258 (37%) patients who were medically managed, 44 (17%) died during admission, 14 (5.4%) of which were aortic related deaths. Four hundred forty-four (63%) patients underwent TEVAR and 343 of which underwent TEVAR within 24 hours of admission. Among TEVAR patients, 39 (8.8%) patients died and 7 (1.6%) had aortic related deaths ( Table 1 ). Comparison of the STREAMLINE and LR model showed no significant difference in ROC curves and high AUCs of 0.869 (95% confidence interval, 0.813-0.925) and 0.840 (95% confidence interval, 0.779-0.900) respectively in predicting in-hospital mortality. Unexpectedly, however, the variables prioritized in each model differed between models. The top 3 variables identified from the LR model were similar to that from existing literature. The STREAMLINE model, however, prioritized location of the injury along the lesser curve, age and aortic injury grade. CONCLUSION: Machine learning provides insight on prioritization of variables not typically identified in standard multivariable logistic regression. Further investigation and validation in other aortic injury cohorts are needed to delineate the utility of ML models. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

The presence of a splenic subcapsular hematoma (SCH) has been associated with higher rates of failure of nonoperative management (FNOM) in patients with blunt splenic injury (BSI), with rates up to 80%. We hypothesized that contemporary rates are lower. A retrospective review was conducted of patients admitted with BSI to a level I trauma center (2016-2021). Patients with SCH who had FNOM were compared to those who did not. There were 661 BSI patients, of which 102 (15.4%) had SCH. Among the SCH patients, 8 (7.8%) had FNOM. Failure of nonoperative management was higher in patients who had a SCH measuring 15 mm or greater. To the best of our knowledge, this is the largest study to date examining the relationship between SCH and FNOM. The presence of a SCH alone is not associated with a high risk for FNOM contrary to previous literature. However, SCH thickness was larger in those who failed.

OBJECTIVE: Breastfeeding is a highly demanding experience, especially for surgical residents who pump after returning to work. We believe that there are obstacles to pumping and opportunities exist to improve support for this group. The objective of this study was to understand the experience of breastfeeding surgery residents and find opportunities for increased support. DESIGN: Surveys were sent out through the Association of Program Directors in Surgery for distribution among current residents. A survey was also conducted in a private group of surgeon mothers to identify those who had previously been breastfeeding during residency. SETTING: All surveys were performed online with results collected in a REDCap web-based application. PARTICIPANTS: Participants were those who gave birth during their surgical residency. RESULTS: 67% of the 246 survey respondents stated that they did not have adequate time for pumping and 56% rarely had access to a lactation room. 69% of mothers reported a reduction in milk supply and 64% stated that the time constraints of residency shortened the total duration they breastfed. 59% of women did not feel comfortable asking to pump. CONCLUSIONS: Surgical residents reported a lack of space, resources, and dedicated time for pumping. These deficiencies contribute to shorter breastfeeding duration. It is crucial to provide lactation rooms and to foster a supportive culture.

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) is the standard of care for the treatment of blunt thoracic aortic injury (BTAI) requiring intervention. Data suggest that low-grade BTAI (grade I [intimal tears] or grade II [intramural hematoma]) will resolve spontaneously if treated with nonoperative management (NOM) alone. There has been no comparison specifically between the use of NOM vs TEVAR for low-grade BTAI. We hypothesize that these low-grade injuries can be safely managed with NOM alone. STUDY DESIGN: Retrospective analysis of all patients with a low-grade BTAI in the Aortic Trauma Foundation Registry from 2016 to 2021 was performed. The study population was 1 primary outcome was mortality. Secondary outcomes included complications, ICU length of stay, and ventilator days. RESULTS: A total of 880 patients with BTAI were enrolled. Of the 269 patients with low-grade BTAI, 218 (81%) were treated with NOM alone (81% grade I, 19% grade II), whereas 51 (19%) underwent a TEVAR (20% grade I, 80% grade II). There was no difference in demographic or mechanism of injury in patients with low-grade BTAI who underwent NOM vs TEVAR. There was a difference in mortality between NOM alone and TEVAR (8% vs 18%, p = 0.009). Aortic-related mortality was 0.5% in the NOM group and 4% in the TEVAR group (p = 0.06). Hospital and ICU length of stay and ventilator days were not different between the 2 groups. CONCLUSIONS: NOM alone is safe and appropriate management for low-grade BTAI, with lower mortality and decreased rates of complication when compared with routine initial TEVAR.

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has the potential to cause clinically relevant systemic ischemic burden with long durations of aortic occlusion (AO). We aimed to examine the association between balloon occlusion time and clinical complications and mortality outcomes in patients undergoing zone 1 REBOA. METHODS: A retrospective cohort analysis of American Association for the Surgery of Trauma Aortic Occlusion for Resuscitation in Trauma and Acuteregistry patients with Zone 1 REBOA between 2013 and 2022 was performed. Patients with cardiopulmonary resuscitation on arrival or who did not survive past the emergency department were excluded. Total AO times were categorized as follows: <15 min, 15-30 min, 31-60 min, and >60 min. Clinical and procedural variables and in-hospital outcomes were compared across groups using bivariate and multivariate regression analyses. RESULTS: There were 327 cases meeting inclusion criteria (n = 51 < 15 min, 83 15-30 min, 98 31-60 min, and 95 > 60 min, respectively). AO >60 min had higher admission lactate (8 ± 6; P = 0.004) compared to all other time groups, but injury severity score, heart rate, and systolic blood pressure were similar. Group average times from admission to definitive hemorrhage control ranged from 82 to 103 min and were similar across groups (85 min in AO >60 group). Longer AO times were associated with greater red blood cell, fresh frozen plasma transfusions (P < 0.001), and vasopressor use (P = 0.001). Mortality was greatest in the >60 min group (73%) versus the <15 min, 15-30 min, and 31-60 min groups (53%, 43%, and 45%, P < 0.001). With adjustment for injury severity score, systolic blood pressure, and lactate, AO >60 min had greater mortality (OR 3.7, 95% CI 1.6-9.4; P < 0.001) than other AO duration groups. Among 153 survivors, AO >60 min had a higher rate of multiple organ failure (15.4%) compared to the other AO durations (0%, 0%, and 4%, P = 0.02). There were no differences in amputation rates (0.7%) or spinal cord ischemia (1.4%). acute kidney injury was seen in 41% of >60 min versus 21%, 27%, and 33%, P = 0.42. CONCLUSIONS: Though greater preocclusion physiologic injury may have been present, REBOA-induced ischemic insult was correlated with poor patient outcomes, specifically, REBOA inflation time >60 min had higher rates of mortality and multiple organ failure. Minimizing AO duration should be prioritized, and AO should not delay achieving definitive hemostasis. Partial REBOA may be a solution to extend safe AO time and deserves further study.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) could prevent lethal exsanguination and support cardiopulmonary resuscitation. In prehospital trauma and medical emergency settings, a small population with high mortality rates could potentially benefit from early REBOA deployment. However, its use in these situations remains highly disputed. Since publication of the first Delphi study on REBOA, in which consensus was not reached on all addressed topics, new literature has emerged. The aim of this study was to establish consensus on the use and implementation of REBOA in civilian prehospital settings for noncompressible truncal hemorrhage and out-of-hospital cardiac arrest as well as for various in-hospital settings. METHODS: A Delphi study consisting of three rounds of questionnaires was conducted based on a review of recent literature. REBOA experts with different medical specialties, backgrounds, and work environments were invited for the international panel. Consensus was reached when a minimum of 75% of panelists responded to a question and at least 75% (positive) or less than 25% (negative) of these respondents agreed on the questioned subject. RESULTS: Panel members reached consensus on potential (contra)indications, physiological thresholds for patient selection, the use of ultrasound and practical, and technical aspects for early femoral artery access and prehospital REBOA. CONCLUSION: The international expert panel agreed that REBOA can be used in civilian prehospital settings for temporary control of noncompressible truncal hemorrhage, provided that personnel are properly trained and protocols are established. For prehospital REBOA and early femoral artery access, consensus was reached on (contra)indications, physiological thresholds and practical aspects. The panel recommends the initiation of a randomized clinical trial investigating the use of prehospital REBOA for noncompressible truncal hemorrhage. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level V.

BACKGROUND: Systolic blood pressure (SBP) is a potential indicator that could guide when to use a resuscitative endovascular balloon occlusion of the aorta (REBOA) in trauma patients with life-threatening injuries. This study aims to determine the optimal SBP threshold for REBOA placement by analyzing the association between SBP pre-REBOA and 24-hour mortality in severely injured hemodynamically unstable trauma patients. METHODS: We performed a pooled analysis of the aortic balloon occlusion (ABO) trauma and AORTA registries. These databases record the details related to the use of REBOA and include data from 14 countries worldwide. We included patients who had suffered penetrating and/or blunt trauma. Patients who arrived at the hospital with a SBP pre-REBOA of 0 mm Hg and remained at 0 mm Hg after balloon inflation were excluded. We evaluated the impact that SBP pre-REBOA had on the probability of death in the first 24 hours. RESULTS: A total of 1,107 patients underwent endovascular aortic occlusion, of these, 848 met inclusion criteria. The median age was 44 years (interquartile range [IQR], 27-59 years) and 643 (76%) were male. The median injury severity score was 34 (IQR, 25-45). The median SBP pre-REBOA was 65 mm Hg (IQR, 49-88 mm Hg). Mortality at 24 hours was reported in 279 (32%) patients. Math modeling shows that predicted probabilities of the primary outcome increased steadily in SBP pre-REBOA below 100 mm Hg. Multivariable mixed-effects analysis shows that when SBP pre-REBOA was lower than 60 mm Hg, the risk of death was more than 50% (relative risk, 1.5; 95% confidence interval, 1.17-1.92; p = 0.001). DISCUSSION: In patients who do not respond to initial resuscitation, the use of REBOA in SBPs between 60 mm Hg and 80 mm Hg may be a useful tool in resuscitation efforts before further decompensation or complete cardiovascular collapse. The findings from our study are clinically important as a first step in identifying candidates for REBOA. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

OBJECTIVE: This study aims to assess the change in cervical spine (C-spine) immobilization frequency in trauma patients over time. We hypothesize that the frequency of unnecessary C-spine immobilization has decreased. METHODS: A retrospective chart review of adult trauma patients transported to our American College of Surgeons-verified Level I trauma center from January 1, 2014, to December 31, 2021, was performed. Emergency medical services documentation was manually reviewed to record prehospital physiology and the application of a prehospital cervical collar (c-collar). C-spine injuries were defined as cervical vertebral fractures and/or spinal cord injuries. Univariate and year-by-year trend analyses were used to assess changes in C-spine injury and immobilization frequency. RESULTS: Among 2906 patients meeting inclusion criteria, 12% sustained C-spine injuries, while 88% did not. Patients with C-spine injuries were more likely to experience blunt trauma (95% vs. 68%, p < 0.001), were older (46 years vs. 41 years, p < 0.001), and had higher Injury Severity Scores (31 vs. 18, p < 0.001). They also exhibited lower initial systolic blood pressures (108 mm Hg vs. 119 mm Hg, p < 0.001), lower heart rates (92 beats/min vs. 97 beats/min, p < 0.05), and lower Glasgow Coma Scale scores (9 vs. 11, p < 0.001). In blunt trauma, c-collars were applied to 83% of patients with C-spine injuries and 75% without; for penetrating trauma, c-collars were applied to 50% of patients with C-spine injuries and only 8% without. Among penetrating trauma patients with C-spine injury, all patients either arrived quadriplegic or did not require emergent neurosurgical intervention. The proportion of patients receiving a c-collar decreased in both blunt and penetrating traumas from 2014 to 2021 (blunt-82% in 2014 to 68% in 2021; penetrating-24% in 2014 to 6% in 2021). CONCLUSIONS: Unnecessary C-spine stabilization has decreased from 2014 to 2021. However, c-collars are still being applied to patients who do not need them, both in blunt and in penetrating trauma cases, while not being applied to patients who would benefit from them.

BACKGROUND: Splenic embolization for traumatic vascular abnormalities in stable patients is a common practice. We hypothesize that modern contrast-enhanced computed tomography (CT) over diagnoses posttraumatic splenic vascular lesions, such as intraparenchymal pseudoaneurysms (PSA) that may not require embolization. METHODS: We reviewed the experience at our high-volume center with endovascular management of blunt splenic injuries from January 2016 to December 2021. Multidisciplinary review was used to compared initial CT findings with subsequent angiography, analyzing management and outcomes of identified vascular lesions. RESULTS: Of 853 splenic injuries managed overall during the study period, 255 (29.9%) underwent angiography of the spleen at any point during hospitalization. Vascular lesions were identified on 58% of initial CTs; extravasation (12.2%) and PSA (51.0%). Angiography was performed a mean of 22 hours after admission, with 38% done within 6 hours. Embolization was performed for 90.5% (231) of patients. Among the 130 patients with PSA on initial CT, 36 (27.7%) had no visible lesion on subsequent angiogram. From the 125 individuals who did not have a PSA identified on their initial CT, 67 (54%) had a PSA seen on subsequent angiography. On postembolization CT at 48 hours to 72 hours, persistently perfused splenic PSAs were seen in 41.0% (48/117) of those with and 22.2% (2/9) without embolization. Only one of 24 (4.1%) patients with PSA on angiography observed without embolization required delayed splenectomy, whereas 6.9% (16/231) in the embolized group had splenectomy at a mean of 5.5 ± 4 days after admission. CONCLUSION: There is a high rate of discordance between CT and angiographic identification of splenic PSAs. Even when identified at angiogram and embolized, close to half will remain perfused on follow-up imaging. These findings question the use of routine angioembolization for all splenic PSAs. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

INTRODUCTION: Aggressive prehospital interventions (PHI) in trauma may not improve outcomes compared to prioritizing rapid transport. The aim of this study was to quantify temporal changes in the frequency of PHI performed by EMS. METHODS: Retrospective chart review of adult patients transported by EMS to our trauma center from January 1, 2014 to 12/31/2021. PHI were recorded and annual changes in their frequency were assessed via year-by-year trend analysis and multivariate regression. RESULTS: Between the first and last year of the study period, the frequency of thoracostomy (6% vs. 9%, p â= â0.001), TXA administration (0.3% vs. 33%, p â< â0.001), and whole blood administration (0% vs. 20%, p â< â0.001) increased. Advanced airway procedures (21% vs. 12%, p â< â0.001) and IV fluid administration (57% vs. 36%, p â< â0.001) decreased. ED mortality decreased from 8% to 5% (p â= â0.001) over the study period. On multivariate regression, no PHI were independently associated with increased or decreased ED mortality. CONCLUSION: PHI have changed significantly over the past eight years. However, no PHI were independently associated with increased or decreased ED mortality.

BACKGROUND: Tranexamic acid (TXA) is associated with lower mortality and transfusion requirements in trauma patients, but its role in thrombotic complications associated with vascular repairs remains unclear. We investigated whether TXA increases the risk of thrombosis-related technical failure (TRTF) in major vascular injuries (MVI). METHODS: The PROspective Observational Vascular Injury Treatment (PROOVIT) registry was queried from 2013 to 2022 for MVI repaired with an open or endovascular intervention. The relationship between TXA administration and TRTF was examined. RESULTS: The TXA group (n = 297) had higher rates of hypotension at admission (33.6% vs. 11.5%, p < 0.001), need for continuous vasopressors (41.4% vs. 18.4%, p < 0.001), and packed red blood cell transfusion (3.2 vs. 2.0 units, p < 0.001) during the first 24 hours compared with the non-TXA group (n = 1941), although demographics, injury pattern, and interventions were similar. Cryoprecipitate (9.1% vs. 2%, p < 0.001), and anticoagulant administration during the intervention (32.7% vs. 43.8%, p < 0.001) were higher in the TXA group; there was no difference in the rate of factor VII use between groups (1% vs. 0.7%, p = 0.485). Thrombosis-related technical failure was not different between the groups (6.3% vs. 3.8 p = 0.141) while the rate of immediate need for reoperation (10.1% vs. 5.7%, p = 0.006) and overall reoperation (11.4% vs. 7%, p = 0.009) was significantly higher in the TXA group on univariate analysis. There was no significant association between TXA and a higher rate of immediate need for reintervention (odds ratio [OR], 1.19; 95% confidence interval [CI], 0.75-1.88; p = 0.465), overall reoperation rate (OR, 1.33; 95% CI, 0.82-2.17; p = 0.249) and thrombotic events in a repaired vessel (OR, 1.07; 95% CI, 0.60-1.92; p = 0.806) after adjusting for type of injury, vasopressor infusions, blood product and anticoagulant administration, and hemodynamics. CONCLUSION: Tranexamic acid is not associated with a higher risk of thrombosis-related technical failure in traumatic injuries requiring major vascular repairs. Further prospective studies to examine dose-dependent or time-dependent associations between TXA and thrombotic events in MVIs are needed. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

BACKGROUND: The objective of our present effort was to use an international blunt thoracic aortic injury (BTAI) registry to create a prediction model identifying important preoperative and intraoperative factors associated with postoperative mortality, and to develop and validate a simple risk prediction tool that could assist with patient selection and risk stratification in this patient population. METHODS: For the purpose of the present study, all patients undergoing thoracic endovascular aortic repair (TEVAR) for BTAI and registered in the Aortic Trauma Foundation (ATF) database from January 2016 as of June 2022 were identified. Patients undergoing medical management or open repair were excluded. The primary outcome was binary in-hospital all-cause mortality. Two predictive models were generated: a preoperative model (i.e. only including variables before TEVAR or intention-to-treat) and a full model (i.e. also including variables after TEVAR or per-protocol). RESULTS: Out of a total of 944 cases included in the ATF registry until June 2022, 448 underwent TEVAR and were included in the study population. TEVAR for BTAI was associated with an 8.5% in-hospital all-cause mortality in the ATF dataset. These study subjects were subsequently divided using 3:1 random sampling in a derivation cohort (336; 75.0%) and a validation cohort (112; 25.0%). The median age was 38 years, and the majority of patients were male (350; 78%). A total of 38 variables were included in the final analysis. Of these, 17 variables were considered in the preoperative model, 9 variables were integrated in the full model, and 12 variables were excluded owing to either extremely low variance or strong correlation with other variables. The calibration graphs showed how both models from the ATF dataset tended to underestimate risk, mainly in intermediate-risk cases. The discriminative capacity was moderate in all models; the best performing model was the full model from the ATF dataset, as evident from both the Receiver Operating Characteristic curve (Area Under the Curve 0.84; 95% CI 0.74-0.91) and from the density graph. CONCLUSIONS: In this study, we developed and validated a contemporary risk prediction model, which incorporates several preoperative and postoperative variables and is strongly predictive of early mortality. While this model can reasonably predict in-hospital all-cause mortality, thereby assisting physicians with risk-stratification as well as inform patients and their caregivers, its intrinsic limitations must be taken into account and it should only be considered an adjunctive tool that may complement clinical judgment and shared decision-making.

INTRODUCTION: With the use of resuscitative endovascular balloon occlusion of the aorta (REBOA) comes the potential for vascular access site complications (VASCs) and limb ischemic sequelae. We aimed to determine the prevalence of VASC and associated clinical and technical factors. METHODS: A retrospective cohort analysis of 24-h survivors undergoing percutaneous REBOA via the femoral artery in the American Association for the Surgery of Trauma Aortic Occlusion for Resuscitation in Trauma and Acute care surgery registry between Oct 2013 and Sep 2021 was performed. The primary outcome was VASC, defined as at least one of the following: hematoma, pseudoaneurysm, arteriovenous fistula, arterial stenosis, or the use of patch angioplasty for arterial closure. Associated clinical and procedural variables were examined. Data were analyzed using Fisher exact test, Mann-Whitney-U tests, and linear regression. RESULTS: There were 34 (7%) cases with VASC among 485 meeting inclusion criteria. Hematoma (40%) was the most common, followed by pseudoaneurysm (26%) and patch angioplasty (21%). No differences in demographics or injury/shock severity were noted between cases with and without VASC. The use of ultrasound (US) was protective (VASC, 35% versus no VASC, 51%; P = 0.05). The VASC rate in US cases was 12/242 (5%) versus 22/240 (9.2%) without US. Arterial sheath size >7 Fr was not associated with VASC. US use increased over time (R2 = 0.94, P < 0.001) with a stable rate of VASC (R2 = 0.78, P = 0.61). VASC were associated with limb ischemia (VASC, 15% versus no VASC, 4%; P = 0.006) and arterial bypass procedures (VASC 3% versus no VASC 0%; P < 0.001) but amputation was uncommon (VASC, 3% versus no VASC, 0.4%; P = 0.07). CONCLUSIONS: Percutaneous femoral REBOA had a 7% VASC rate which was stable over time. VASC are associated with limb ischemia but need for surgical intervention and/or amputation is rare. The use of US-guided access appears to be protective against VASC and is recommended for use in all percutaneous femoral REBOA procedures.
