RESUMEN
CONTEXT: Withdrawal of life-sustaining therapies (WDLST) in young individuals with traumatic brain injury (TBI) is an overwhelming situation often made more stressful by socioeconomic factors that shape health outcomes. Identifying these factors is crucial to developing equitable and goal-concordant care for patients and families. OBJECTIVES: We aimed to identify predictors of WDLST in young patients with 1-TBI. We hypothesized uninsured payment method, race, and co-morbid status are associated with WDLST. METHODS: We queried the 2021 Trauma Quality Improvement Program database for patients <45 years with TBI. Patients with WDLST were compared to patients without WDLST. Multivariable logistic regression (MLR) was performed. RESULTS: 61,115 patients were included, of whom 2,487 (4.1%) underwent WDLST. Patients in the WDLST cohort were older (29 vs 27, P<0.001), more likely to suffer from a penetrating mechanism (29% vs 11%, P<.0001), and have uninsured (22% vs 18%) or other payment method (5% vs 3%) when compared to the non-WDLST cohort. MLR identified age (AOR:1.019, 95% CI 1.014-1.024, P<.0001), non-Hispanic ethnicity (AOR:1.590, 95% CI 1.373-1.841, P<.0001), penetrating mechanism (AOR:3.075, 95% CI 2.727-3.467, P<.0001), systolic blood pressure (AOR: 0.992, 95% CI 0.990-0.993, P<0.0001), advanced directive (AOR:4.987, 95% CI 2.823-8.812, P<.0001), cirrhosis (AOR:3.854, 95% CI 2.641-5.625, P<.0001), disseminated cancer (AOR:6.595, 95% CI 2.370-18.357, P=0.0003), and interfacility transfer (AOR:1.457, 95% CI 1.295-1.640, P<0.0001) as factors associated with WDLST. Black patients were less likely to undergo WDLST when compared to white patients (AOR:0.687, 95% CI 0.603-0.782, P<.0001). CONCLUSION: The decision for WDLST in young patients with severe TBI may be influenced by cultural and socioeconomic factors in addition to clinical considerations.
RESUMEN
BACKGROUND AND OBJECTIVES: The management of blunt cerebrovascular injuries (BCVIs) remains an important topic within trauma and neurosurgery today. There remains a lack of consensus within the literature and significant variation across institutions. The purpose of this study was to evaluate management of BCVI at a large, tertiary referral trauma center. METHODS: Institutional Review Board approval was obtained to conduct a retrospective review of patients with BCVI at our Level 1 Trauma Center. Computed tomography angiography was used to identify BCVI for each patient. Patient information was collected, and statistical analysis was performed. With the included risk factors for ischemic complications, a novel scoring system based on ischemic risk, the "Memphis Score," was developed and evaluated to grade BCVI. RESULTS: Two hundred seventeen patients with BCVI from July 2020 to August 2022 were identified. The most common mechanism of injury was motor vehicle collision (141, 65.0%). Vertebral arteries were the most common vessel injured (136, 51.1%) with most injuries occurring at a high cervical location (101, 38.0%). Denver Grade 1 injuries (89, 33.5%) and a Memphis Score of 1 were most frequent (172, 64.6%), and initial anticoagulation with heparin drip was initiated 56.7% of the time (123). Endovascular treatment was required in 24 patients (11.1%) and was usually performed in the first 48 hours (15, 62.5%). While Denver Grade (P = .019) and Memphis Score (P < .00001) were significantly higher in those patients undergoing endovascular treatment, only the Memphis Score demonstrated a significant difference between those patients who had stroke or worsening on follow-up imaging and those who did not (P = .0009). CONCLUSION: Although BCVI management has improved since early investigative efforts, institutions must evaluate and share their data to help clarify outcomes. The novel "Memphis Score" presents a standardized framework to communicate ischemic risk and guide management of BCVI.
RESUMEN
INTRODUCTION: Management of penetrating neck injuries (PNIs) has evolved over time, more frequently relying on increased utilization of diagnostic imaging studies. Directed work-up with computed tomography imaging has resulted in increased use of angiography and decreased operative interventions. We sought to evaluate management strategies after directed work-up, hypothesizing increased use of non-operative therapeutic interventions and lower mortality after directed work-up. METHODS: Patients with PNI from 2017 to 2022 were identified from a single-center trauma registry. Demographics, injuries, physical exam findings, diagnostic studies and interventions were collected. Patients were stratified by presence of hard signs and management strategy [directed work-up (DW) and immediate operative intervention (OR)] and compared. Outcomes included therapeutic non-operative intervention [endovascular stent, embolization, dual antiplatelet therapy (DAPT), or anticoagulation (AC)], non-therapeutic neck exploration, length of stay (LOS), and mortality. RESULTS: Of 436 patients with PNI, 143 (33%) patients had vascular and/or aerodigestive injuries. Of these, 115 (80%) patients underwent DW and 28 (20%) patients underwent OR. There were no differences in demographics or injury severity score between groups. Patients in the DW group were more likely to undergo vascular stent or embolization (p = 0.040) and had fewer non-therapeutic neck explorations (p = 0.0009), compared to the OR group. There were no differences in post-intervention stroke, leak, or mortality. Sixty percent of patients with vascular hard signs and 78% of patients with aerodigestive hard signs underwent DW. CONCLUSIONS: Directed work-up in select patients with PNI is associated with fewer non-therapeutic neck explorations. There was no difference in mortality. Selective use of endovascular management, AC and DAPT is safe.

INTRODUCTION: Historically, a zone II hematoma mandated exploration after penetrating trauma, but this has been challenged given potentially higher nephrectomy rates and the advent of therapeutic endovascular and endoscopic interventions. We hypothesized penetrating mechanism was not a predictor for delayed intervention in the modern era. METHODS: This single-center, retrospective study included renal trauma patients from 3/2019 to 6/2022. Our institutional practice is selective exploration of zone II hematomas for active bleeding and expanding hematoma only, regardless of mechanism. Descriptive statistics and multivariable logistic regression (MLR) were performed. RESULTS: One-hundred and forty-four patients were identified, with median age 32 years (IQR:23,49), 66% blunt mechanism, and injury severity score 17(IQR:11,26). Forty-three (30%) required operative intervention, and of the 20 that had a zone II exploration, 3 (15%) underwent renorrhaphy and 17 (85%) underwent nephrectomy. Penetrating patients more frequently underwent immediate operative intervention (67%vs10%,P < .0001), required nephrectomy (27%vs5%,P = .0003), and were less likely to undergo pre-intervention CT (51%vs96%,P < .0001) compared to blunt patients. Delayed renal interventions were higher in penetrating (33%vs13%,P = .004) with no difference in mortality or length of stay compared to blunt mechanism. Ureteral stent placement and renal embolization were the most common delayed interventions. On MLR, the only independent predictor for delayed intervention was need for initial operative intervention (OR 3.803;95%CI:1.612-8.975,P = .0023). Four (3%) required delayed nephrectomy, of which only one underwent initial operative intervention without zone 2 exploration. CONCLUSIONS: The most common delayed interventions after renal trauma were renal embolization and ureteral stent. Penetrating mechanism was not a predictor of delayed renal intervention in a trauma center that manages zone II retroperitoneal hematomas similarly regardless of mechanism.

BACKGROUND: The management of extraperitoneal bladder injuries (EBIs) when present with concomitant pelvic fractures is controversial. Current evidence is divided between supporting non-operative management with catheter drainage compared to operative management of bladder injury. The purpose of this study was to evaluate current management of EBI in the setting of pelvic fractures at our institution. We hypothesize there is no difference between operative and non-operative groups. METHODS: Retrospective review of patients with concomitant bladder injuries and pelvic fractures at a level 1 trauma center from 2017 to 2022 was performed. Demographics, injury characteristics, management strategies, and complications were collected. Patients were stratified by management (cystorrhaphy vs non-operative) and compared. RESULTS: Of 90 patients with bladder injuries and pelvic fractures, 50 patients (56%) presented with EBI, 26 patients (29%) presented with only intraperitoneal injuries, and 14 patients (16%) presented with a combined injury. Of patients with EBI, 18 (36%) underwent cystorrhaphy and 32 (64%) underwent non-operative management. There was no difference in demographics, orthopedic pelvic operative intervention, length of stay, or mortality between groups. Patients in the operative cohort had more bladder leaks [7 (39%) vs 4 (13%), P = .0406], compared to those in the non-operative cohort. Composite complications [7 (39%) vs 7 (22%), P = .1984] were similar between groups. CONCLUSIONS: Patients with EBI and pelvic fractures who underwent cystorrhaphy had more bladder leaks on follow-up imaging, although there was no difference in composite complications, when compared to those who underwent non-operative management.

BACKGROUND: Despite improving understanding of trauma-induced coagulopathy (TIC), mortality and morbidity due to exsanguinating trauma remain high. Increased complications due to hemorrhage have been reported in blood group O, possibly due to reduced levels of von Willebrand factor (vWF). METHODS: An urban level 1 adult trauma center registry was retrospectively queried. Patients receiving ≥6 units of pRBC within 4 âh of presentation were included. Patient demographics, admission labs and outcomes were obtained. Univariate and multiple logistic regression analyses were performed. RESULTS: 562 patients were identified. There were no significant differences in demographics, admission labs, or outcome between different ABO groups. After adjustment, Type A patients were more likely to be hypocoagulable compared to Type O patients (p â= â0.014). No mortality differences were seen between ABO types in multiple regression analysis. CONCLUSIONS: No outcome or mortality differences were seen between ABO types, therefore factors other than vWF expression should be considered to explain coagulopathy in trauma patients.

Introduction: Optimal venous thromboembolism (VTE) enoxaparin prophylaxis dosing remains elusive. Weight-based (WB) dosing safely increases anti-factor Xa levels without the need for routine monitoring but it is unclear if it leads to lower VTE risk. We hypothesized that WB dosing would decrease VTE risk compared with standard fixed dosing (SFD). Methods: Patients from the prospective, observational CLOTT-1 registry receiving prophylactic enoxaparin (n=5539) were categorized as WB (0.45-0.55 mg/kg two times per day) or SFD (30 mg two times per day, 40 mg once a day). Multivariate logistic regression was used to generate a predicted probability of VTE for WB and SFD patients. Results: Of 4360 patients analyzed, 1065 (24.4%) were WB and 3295 (75.6%) were SFD. WB patients were younger, female, more severely injured, and underwent major operation or major venous repair at a higher rate than individuals in the SFD group. Obesity was more common among the SFD group. Unadjusted VTE rates were comparable (WB 3.1% vs. SFD 3.9%; p=0.221). Early prophylaxis was associated with lower VTE rate (1.4% vs. 5.0%; p=0.001) and deep vein thrombosis (0.9% vs. 4.4%; p<0.001), but not pulmonary embolism (0.7% vs. 1.4%; p=0.259). After adjustment, VTE incidence did not differ by dosing strategy (adjusted OR (aOR) 0.75, 95% CI 0.38 to 1.48); however, early administration was associated with a significant reduction in VTE (aOR 0.47, 95% CI 0.30 to 0.74). Conclusion: In young trauma patients, WB prophylaxis is not associated with reduced VTE rate when compared with SFD. The timing of the initiation of chemoprophylaxis may be more important than the dosing strategy. Further studies need to evaluate these findings across a wider age and comorbidity spectrum. Level of evidence: Level IV, therapeutic/care management.
RESUMEN
BACKGROUND: Trauma surgical dogma teaches that patients should have intraoperative angiography (IA) if the surgeon cannot identify a pulse in the injured extremity following a vascular repair. This study was undertaken to assess the utility of IA in trauma patients who underwent open brachial or femoral artery revascularization. METHODS: Retrospective analysis of the Prospective Observational Vascular Injury Trial (PROOVIT) database from 2013 to 2021 evaluated patients >15 years with penetrating or blunt injuries requiring operative intervention of the brachial, superficial femoral, or common femoral arteries. Prospective Observational Vascular Injury Trial data evaluated included documented pulse in the injured extremity at revascularization completion, adjunctive IA, immediate revision, and vascular reintervention during the hospitalization. RESULTS: Of the 5057 patients with vascular injury, 185 patients met our inclusion criteria. The majority were male (86.5%) with a median age, injury severity score, and systolic blood pressure of 29, 12, and 117, respectively. Of the study patients, 39% underwent IA, 14% had immediate revision, and 8% required vascular reoperation during their admission. Patients who underwent IA and with no documented palpable pulse after repair were significantly more likely to require immediate revision before leaving the operating room (22% vs 9%, P = .013) and were not more likely to require reoperation, than those who did not undergo IA (7% vs 9%, P = .613). CONCLUSIONS: Intraoperative angiography is a valuable tool for surgeons for vascular extremity trauma and is associated with a greater rate of immediate revision. Familiarity with angiographic technique is essential for vascular trauma and should be a focal point of training.

Recent advancements in genetic testing have revealed cases of mosaicism, demonstrating the phenomenon may be more common than once thought. Broadly defined, mosaicism describes the presence of two genotypically different cell lineages within the same organism. This can arise from small mutations or errors in chromosome segregation, as early as in gametes, before or after fertilization. Mosaicism is directly responsible for many conditions that present in a wide range of tissues, with the presence of the mutation or genetic abnormality following a tissue-dependent pattern. This makes it possible for patients to test negative for a condition using a standard tissue sample while harboring the variant in a different tissue. Understanding the timing and mechanisms of mosaic conditions will aid in targeted testing that is more appropriate to identify a pathogenic variant. This targeted testing should reduce the length of a patient's diagnostic odyssey and provide a better understanding of the chances of passing on their variant to their offspring, thereby allowing for more accurate genetic counseling. We illustrate this phenomenon with two cases: one of Pallister-Killian syndrome and the other of tuberous sclerosis complex. Both patients had increased time to diagnosis because of difficulties in identifying genetic variants in tested tissues. Beyond just increased time to diagnosis, we illustrate that mosaic conditions can present as less severe and more variable than the germline condition and how specific germ layers may be affected by the variant. Knowing which germ layers may be affected by the variant can give clinicians a clue as to which tissues may need to be tested to yield the most accurate result.
