Abstract
Background The thoracic ultrasound (TUS) is a monitoring tool that has gained worldwide popularity in various scenarios, offering the opportunity for dynamic, bedside evaluations. Recent studies indicate that the use of TUS enables the diagnosis of pathologies resulting from blunt chest trauma (BCT), yielding favorable outcomes. This study aimed to compare the utility of TUS versus chest radiography (CXR) in diagnosing pulmonary pathologies resulting from closed-chest traumas. Methodology A prospective cross-sectional study was conducted with a sample of 58 patients diagnosed with BCT who sought emergency care at the "Dr. Luis Razetti" University Hospital in Barcelona, Venezuela, from November 2023 to January 2024. Results Of the patients, 75.9% (n = 44) were male, with an average age of 37.8 years (standard deviation = 18.4 years). Injuries were reported in 8.6% (n = 5) of the patients, including 60% (n = 3) pneumothorax and 40% (n = 2) hemothorax. Ultrasound results coincided with CXR in 94.8% (n = 55) of the cases, with a Cohen's kappa coefficient of 0.9 (95% confidence interval (CI) = 0.642-1.0). TUS demonstrated higher sensitivity than CXR (100% vs. 60%) for detecting hemothorax and pneumothorax in patients with BCT, with an area under the receiver operating characteristic curve of 0.991 (95% CI = 0.968-1.013). Conclusions BCT predominantly occurred in young males, resulting primarily in pneumothorax and hemothorax lesions, detectable with higher sensitivity through TUS compared to CXR. The use of TUS should be considered an essential component of the initial assessment for individuals with BCT.

[PMID: 37845164 DOI: 10.1016/j.acra.2023.08.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 08/25/2023] [Accepted: 08/26/2023] [Indexed: 10/18/2023]
Abstract
RATIONALE AND OBJECTIVES The aim of this study was to compare the use of computed tomography (CT) with automatic rib unfolding and three-dimensional (3D) volume-rendered imaging in the detection and characterization of rib fractures and flail chest. MATERIALS AND METHODS A total of 130 patients with blunt chest trauma underwent whole-body CT, and five independent readers assessed the presence and characterization of rib fractures using traditional CT images, automatic rib unfolding, and 3D volume-rendered images in separate readout sessions at least 2 weeks apart. A gold standard was established by consensus among the readers based on the combined analysis of conventional and reformatted images. RESULTS Automatic rib unfolding significantly reduced mean reading time by 47.5%-74.9% (P < 0.0001) while maintaining a comparable diagnostic performance for rib fractures (positive predictive value [PPV] of 82.1%-93.5%, negative predictive value [NPV] of 96.8%-98.2%, and 69.4%-94.2% and 96.9%-99.1% for conventional axial images and 70.4%-85.1% and 95.2%-96.6% for 3D images) and better interobserver agreement (kappa of 0.74-0.87). For flail chest, automatic rib unfolding showed a PPV of 85.7%-100%, NPV of 90.4%-99.0%, and 80.0%-100% and 89.7%-100% for conventional axial images and 76.9%-100% and 89.0%-92.1% for 3D images. CONCLUSION Automatic rib unfolding demonstrated equivalent diagnostic performance to conventional images in detecting acute rib fractures and flail chest, with good interobserver agreement and time-saving benefits.

Abstract
PURPOSE The utility of chest computed tomography (CCT) is not well established in the diagnostic algorithm of adolescent blunt trauma patients. Our study's aim was to review CCT usage in the initial evaluation of adolescent blunt trauma. METHODS We retrospectively reviewed adolescent blunt trauma patients treated at our urban level 1 adult trauma center from 2015 to 2019. Our primary outcome was the rate of positive CCT findings. Univariate and multivariate logistic regression analyses were performed. RESULTS There were 288 patients that met our inclusion criteria and 153 positive CCT and 135 negative CCT. There was no statistically significant difference between both groups in terms of age, gender, and race. Those with a positive CCT were found to have a statistically significant higher ISS than the negative CCT group (20.6 ± 12.3 vs 12.3 ± 7.6; P < .01). Those with a positive CCT were more likely to have a GCS <15 (40% vs 25%), have a positive CXR (38% vs 2%), have chest pain (16% vs 7%), and have an abnormal chest exam (27% vs 7%) than those with a negative CCT (P < .01). On multivariate analysis, positive CXR (P < .05, OR = 13.96) and ISS (P < .05, OR = 3.10) were independently associated with a positive CCT. CONCLUSION While CCT may provide valuable information, clinical exam coupled with low-ionizing radiographic imaging (i.e., CXR) may sufficiently identify chest trauma after blunt mechanisms. This shift in management can potentially reduce the risk of radiation without compromising the care of adolescent trauma patients at adult trauma centers.

Abstract
INTRODUCTION The purpose of this study is to evaluate the ability of musculoskeletal radiologists to diagnose sternoclavicular joint injuries in the standard CT imaging planes compared to 3D volume rendered images to define the most accurate plane to improve prospective diagnosis. MATERIALS AND METHODS A retrospective query of our institutional database was performed. Twenty-six patients with a diagnosis of sternoclavicular joint injury, who had been evaluated with CT and treated by orthopedic surgery, and 30 control patients who did not have a sternoclavicular joint injury were included for analysis. Two blinded radiologists with specialty training in musculoskeletal radiology independently reviewed axial, coronal, sagittal, and 3D reformatted CT images and documented whether injury was present or not present. RESULTS Accuracy was good for both radiologists on all views. It was lowest on the sagittal view for both readers. Accuracy was highest for the 3D view. When comparing the accuracy of the four views for each radiologist, there was a significant difference for Radiologist A, whose 3D images were more accurate compared to the axial and sagittal views. There was no significant difference for Radiologist B. There was good inter-reader agreement, which was highest on the 3D images. CONCLUSION 3D volume renderings of the sternoclavicular joints have the potential to improve radiologist accuracy for detection of sternoclavicular joint injury/dislocation in the setting of chest well trauma, which could decrease instances of missed or delayed diagnosis.

Abstract
Automobile crashes and blunt trauma often lead to life-threatening thoracic injuries, especially to the lung tissues. These injuries can be simulated using finite element-based human body models that need dynamic material properties of lung tissue. The strain-rate-dependent material parameters of human parenchymal tissues were determined in this study using uniaxial quasi-static (1 mm/s) and dynamic (1.6, 3, and 5 m/s) compression tests. A bilinear material model was used to capture the nonlinear behavior of the lung tissue, which was implemented using a user-defined material in LS-DYNA. Inverse mapping using genetic algorithm-based optimization of all experimental data with the corresponding FE models yielded a set of strain-rate-dependent material parameters. The bilinear material parameters are obtained for the strain rates of 0.1, 100, 300, and 500 s-1. The estimated elastic modulus increased from 43 to 153 kPa, while the toe strain reduced from 0.39 to 0.29 when the strain rate was increased from 0.1 to 500 s-1. The optimized bilinear material properties of parenchymal tissue exhibit a piecewise linear relationship with the strain rate.

Abstract
While aortic injury is the most commonly cited thoracic arterial injury, non-aortic arterial injuries represent an uncommon but significant source of morbidity and mortality in blunt and penetrating thoracic trauma patients. Knowledge of the spectrum of vascular injury and anatomic considerations that dictate patterns of associated thoracic hemorrhage will assist the radiologist in the accurate and efficient diagnosis of these injuries. This article provides a review of anatomy, pertinent clinical exam and CT angiography findings, as well as therapeutic options for non-aortic thoracic arterial trauma.

Abstract
INTRODUCTION Blast injury is a unique condition that carries a high rate of morbidity and mortality, often with mixed penetrating and blunt injuries. OBJECTIVE This review highlights the pearls and pitfalls of blast injuries, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION Explosions may impact multiple organ systems through several mechanisms. Patients with suspected blast injury and multisystem trauma require a systematic evaluation and resuscitation, as well as investigation for injuries specific to blast injuries. Blast injuries most commonly affect air-filled organs but can also result in severe cardiac and brain injury. Understanding blast injury patterns and presentations is essential to avoid misdiagnosis and balance treatment of competing interests of patients with polytrauma. Management of blast victims can also be further complicated by burns, crush injury, resource limitation, and wound infection. Given the significant morbidity and mortality associated with blast injury, identification of various injury patterns and appropriate management are essential. CONCLUSIONS An understanding of blast injuries can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
PURPOSE Rapid automated CT volumetry of pulmonary contusion may predict progression to Acute Respiratory Distress Syndrome (ARDS) and help guide early clinical management in at-risk trauma patients. This study aims to train and validate state-of-the-art deep learning models to quantify pulmonary contusion as a percentage of total lung volume (Lung Contusion Index, or auto-LCI) and assess the relationship between auto-LCI and relevant clinical outcomes. METHODS 302 adult patients (age ≥ 18) with pulmonary contusion were retrospectively identified from reports between 2016 and 2021. nnU-Net was trained on manual contusion and whole-lung segmentations. Point-of-care candidate variables for multivariate regression included oxygen saturation, heart rate, and systolic blood pressure on admission. Logistic regression was used to assess ARDS risk, and Cox proportional hazards models were used to determine differences in ICU length of stay and mechanical ventilation time. RESULTS Mean Volume Similarity Index and mean Dice scores were 0.82 and 0.67. Interclass correlation coefficient and Pearson r between ground-truth and predicted volumes were 0.90 and 0.91. 38 (14%) patients developed ARDS. In bivariate analysis, auto-LCI was associated with ARDS (p < 0.001), ICU admission (p < 0.001), and need for mechanical ventilation (p < 0.001). In multivariate analyses, auto-LCI was associated with ARDS (p = 0.04), longer length of stay in the ICU (p = 0.02) and longer time on mechanical ventilation (p = 0.04). AUC of multivariate regression to predict ARDS using auto-LCI and clinical variables was 0.70 while AUC using auto-LCI alone was 0.68. CONCLUSION Increasing auto-LCI values corresponded with increased risk of ARDS, longer ICU admissions, and longer periods of mechanical ventilation.

Abstract
Radiologists and trauma surgeons should monitor for early killers among patients with thoracic trauma, such as tension pneumothorax, tracheobronchial injuries, flail chest, aortic injury, mediastinal hematomas, and severe pulmonary parenchymal injury. With the advent of cutting-edge technology, rapid volumetric computed tomography of the chest has become the most definitive diagnostic tool for establishing or excluding thoracic trauma. With the notion of "time is life" at emergency settings, radiologists must find ways to shorten the turnaround time of reports. One way to interpret chest findings is to use a systemic approach, as advocated in this study. Our interpretation of chest findings for thoracic trauma follows the acronym "ABC-Please" in which "A" stands for abnormal air, "B" stands for abnormal bones, "C" stands for abnormal cardiovascular system, and "P" in "Please" stands for abnormal pulmonary parenchyma and vessels. In the future, utilizing an artificial intelligence software can be an alternative, which can highlight significant findings as "warm zones" on the heatmap and can re-prioritize important examinations at the top of the reading list for radiologists to expedite the final reports.

A Prospective Observational Study on the Outcome Assessment of Conservative Management Versus Intercostal Drainage (ICD) in Blunt Chest Injury Patients With ≤3 Rib Fractures in a North Indian Tertiary Care Center. Cureus 2023; 15:e42167. [PMID: 37602137 PMCID: PMC10439305 DOI: 10.7759/cureus.42167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/19/2023] [Indexed: 08/22/2023] Open
Abstract
Introduction Trauma is the third most common cause of death in all age groups. One out of four trauma patients die due to thoracic injury or its complications. Seventy percent of thoracic traumas are due to blunt injury. This indicates the importance of chest trauma among all traumas. Quick and precise assessment bears paramount importance in deciding life-saving and definitive management. Often, the initial management in blunt injury patients is based on subjective assessment by the attending clinician. A scoring system that provides early identification of the patients at the greatest risk for respiratory failure and more likely to require mechanical ventilation and require prolonged care, as well as those with a higher mortality risk, may allow the early institution of intervention to improve outcomes. Thoracic Trauma Severity Score (TTSS) poses to be a precise tool in directing the management modality to be employed. Methodology This was an observational study including 112 patients of age >12 years, with blunt chest injury, sustaining ≤3 rib fractures, and with a stable chest wall. The patients with penetrating injury, those with blunt chest injury having flail segment, patients in the pediatric age group (<12 years), or polytrauma patients were excluded from our study. Of the 112 patients, 56 had been managed by intercostal drainage (ICD), and the rest (56) had been managed conservatively. Result Road traffic accidents (RTA) were the most common mode of injury in both groups. The percentage of the patients with one, two, and three rib fractures was 57.14%, 32.14%, and 10.71%, respectively, in the ICD group and 85.71%, 7.14%, and 7.14%, respectively, in the conservative management group (p = 0.124). The mean TTSS score was significantly more in the ICD group as compared to the conservative management group in the single rib fracture patients (p = 0.001*), as well as all patients of any number of rib fractures (p < 0.01*) (significance was defined as a value of p less than 0.05 {indicated by an asterisk}). The mean hospital stay was significantly lower in the conservative group as compared to the ICD group (p < 0.01*). The mean SF-36 (outcome) was significantly more in the conservative management group as compared to the ICD group (p = 0.020*). The mean cost of treatment was significantly more in the ICD group as compared to the conservative management group (p < 0.001*). Conclusion In our study, a TTSS (as measured by the primary care surgeon) of >7, across any number of rib fractures, was preferably predictive of management by ICD, while a <7 value was favorable for conservative management. TTSS can be used as an important tool to predict the management modality in blunt chest injury patients with ≤3 rib fractures.

Abstract
OBJECTIVE About 60% of multiple trauma patients have thoracic trauma, and thoracic trauma results in the death of 10% of these patients. Computed tomography (CT) is the most sensitive and specific imaging modality for the diagnosis of acute disease, and it helps in the management and prognostic evaluation of patients with high-impact trauma. This paper aims to show the practical points that are key for diagnosing severe non-cardiovascular thoracic trauma by CT. CONCLUSION Knowing the key features of severe acute thoracic trauma on CT is crucial to avoid diagnostic errors. Radiologists play a fundamental role in the accurate early diagnosis of severe non-cardiovascular thoracic trauma, because the patient's management and outcome will depend largely on the imaging findings.

The Role of Thoracic Ultrasound for Diagnosis of Diseases of the Chest Wall, the Mediastinum, and the Diaphragm-Narrative Review and Pictorial Essay. Diagnostics (Basel) 2023; 13:767. [PMID: 36832255 PMCID: PMC9956010 DOI: 10.3390/diagnostics13040767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 01/29/2023] [Accepted: 02/08/2023] [Indexed: 02/22/2023] Open
Abstract
The diagnostic capabilities of ultrasound extend far beyond the evaluation of the pleural space and lungs. Sonographic evaluation of the chest wall is a classic extension of the clinical examination of visible, palpable, or dolent findings. Unclear mass lesions of the chest wall can be differentiated accurately and with low risk by additional techniques such as color Doppler imaging, contrast-enhanced ultrasound, and, in particular, ultrasound-guided biopsy. For imaging of mediastinal pathologies, ultrasound has only a complementary function but is valuable for guidance of percutaneous biopsies of malignant masses. In emergency medicine, ultrasound can verify and support correct positioning of endotracheal tubes. Diaphragmatic ultrasound benefits from the real-time nature of sonographic imaging and is becoming increasingly important for the assessment of diaphragmatic function in long-term ventilated patients. The clinical role of thoracic ultrasound is reviewed in a combination of narrative review and pictorial essay.

Abstract
BACKGROUND. Increases in the use of CT to evaluate patients presenting with trauma have raised concern about inappropriate imaging. The evolving utilization of CT for trauma evaluation may be impacted by injury severity. OBJECTIVE. The purpose of this study was to explore patterns in utilization of chest and abdominopelvic CT among trauma-related emergency department (ED) visits across the United States. METHODS. This retrospective study was conducted with national commercial claims information extracted from the MarketScan Commercial Database. Trauma-related ED encounters were identified from the 2011-2018 MarketScan database files and classified by injury severity score (minor, intermediate, and major injuries) on the basis of International Classification of Diseases codes. ED encounters were also assessed for chest CT, abdominopelvic CT, and single-encounter chest and abdominopelvic CT examinations. Utilization per 1000 trauma-related ED encounters was determined. Multivariable Poisson regression models were used to determine incidence rate ratios (IRRs) as a measure of temporal changes in utilization. RESULTS. From 2011 to 2018, 8,369,092 trauma-related ED encounters were identified (5,685,295 for minor, 2,624,944 for intermediate, and 58,853 for major injuries). Utilization of chest CT per 1000 trauma-related ED encounters increased from 4.9 to 13.5 examinations (adjusted IRR, 1.15 per year; minor injuries, from 2.2 to 7.7 [adjusted IRR, 1.17]; intermediate injuries, from 8.5 to 21.5 [adjusted IRR, 1.16]; major injuries, from 117.8 to 200.1 [adjusted IRR, 1.08]). Utilization of abdominopelvic CT per 1000 trauma-related ED encounters increased from 7.5 to 16.4 (adjusted IRR, 1.12; minor injuries, 4.8 to 12.2 [adjusted IRR, 1.13]; intermediate injuries, 10.6 to 21.7 [adjusted IRR, 1.13]; major injuries, 134.8 to 192.6 [adjusted IRR, 1.07]). Utilization of single-encounter chest and abdominopelvic CT per 1000 trauma-related ED encounters increased from 3.4 to 8.9 [adjusted IRR, 1.16; minor injuries, 1.1 to 4.6 [adjusted IRR, 1.18]; intermediate injuries, 6.4 to 16.4 [adjusted IRR, 1.16]; major injuries, 99.6 to 179.9 [adjusted IRR, 1.08]). CONCLUSION. National utilization of chest and abdominopelvic CT for trauma-related ED encounters increased among commercially insured patients from 2011 to 2018, particularly for single-encounter chest and abdominopelvic CT examinations and for minor injuries. CLINICAL IMPACT. Given concerns about increased cost and detection of incidental findings, further investigation is warranted to explore the potential benefit of single-encounter chest and abdominopelvic CT examinations of patients with minor injuries and to develop strategies for optimizing appropriateness of imaging orders.

Abstract
Background Sternal fractures are not commonly observed in patients with blunt trauma. The routine use of computed tomography (CT) in the evaluation of chest trauma helps identify these fractures. We studied the incidence, injury mechanism, management, and outcome of sternal fractures in patients with blunt trauma treated at our community-based hospital. Methods We retrospectively reviewed the chest CT scans of all patients with blunt trauma who were presented to our community-based hospital from October 2010 to March 2019. The study variables included age at the time of injury, sex, mechanism of injury, type, and site of fracture, associated injuries, Glasgow Coma Scale, Injury Severity Score, need for intensive care unit admission, hospital stay, and long-term outcome. Results In total, 5632 patients with blunt trauma presented to our hospital during the study period, and chest CT scan was performed for 2578 patients. Sternal fractures were diagnosed in 63 patients. The primary mechanism of injury was a motor vehicle collision. The most common site of fracture was the body of the sternum (47 patients; 74.6%). Twenty (31.7%) patients had an isolated sternal fracture with no other injuries. Seven (11.1%) patients were discharged directly from the emergency department. Two patients died (overall mortality rate, 3.2%) and two experienced long-term disability. Conclusions The incidence of sternal fractures in our patient population was similar to that reported by tertiary hospitals. Patients with a sternal fracture and normal cardiac enzyme levels and electrocardiogram may be safely discharged from the emergency department, provided there are no other major injuries.

Abstract
INTRODUCTION Blunt thoracic injury (BTI) is one of the most common causes of trauma admission in the United States and is uncommonly associated with cardiac injuries. Blunt cardiac injury (BCI) after blunt thoracic trauma is infrequent but carries a substantial risk of morbidity and sudden mortality. Our study aims to identify predictors of concomitant cardiac contusion among BTI patients and the predictors of mortality among patients presenting with BCI on a national level. MATERIALS AND METHODS We performed a 1-y (2017) analysis of the American College of Surgeons Trauma Quality Improvement Program. We included all adults (aged ≥ 18 y) with the diagnosis of BTI. We excluded patients who were transferred, had a penetrating mechanism of injury, and who were dead on arrival. Our primary outcomes were the independent predictors of concomitant cardiac contusions among BTI patients and the predictors of mortality among BCI patients. Our secondary outcome measures were in-hospital complications, differences in injury patterns, and injury severity between the survivors and nonsurvivors of BCI. RESULTS A total of 125,696 patients with BTI were identified, of which 2368 patients had BCI. Mean age was 52 ± 20 y, 67% were male, and median injury severity score was 14 [9-21]. The most common type of cardiac injury was cardiac contusion (43%). Age ≥ 65 y, higher 4-h packed red blood cell requirements, motor vehicle collision mechanism of injury, and concomitant thoracic injuries (hemothorax, flail chest, lung contusion, sternal fracture, diaphragmatic injury, and thoracic aortic injuries) were independently associated with concomitant cardiac contusion among BTI patients (P value < 0.05). Age ≥ 65 y, thoracic aortic injury, diaphragmatic injury, hemothorax, and a history of congestive heart failure were independently associated with mortality in BCI patients (P value < 0.05). CONCLUSIONS Predictors of concomitant cardiac contusion among BTI patients and mortality among BCI patients were identified. Guidelines on the management of BCI should incorporate these predictors for timely identification of high-risk patients.

Abstract
To describe imaging findings of pulmonary contusions (PC) in adults and children using multidetector computed tomography (CT) scanners. We conducted a retrospective single center study. All chest multidetector computed tomography (MDCT) scans of victims of blunt trauma admitted to the emergency unit of a reference trauma center of Brazil between January 2015 and December 2016 were reviewed in search of opacities compatible with PC. The CT images were analyzed in conjunction with medical records, that provided demographic and clinical data. The obtained data were analyzed in the overall population and comparing children and adults. Significant P value was defined as <.05. 52.7% of patients presented bilateral opacities. Middle third, posterior and peripheral portions of the lungs were more frequently affected, in the craniocaudal, anteroposterior and axial axes, respectively. A vast majority of patients (80.6%) presented multiple opacities, whereas a minority showed subpleural sparing (26.9%) and fissure crossing (22.6%), with similar frequencies in children and adults. Children, although, more frequently presented consolidation and more diffuse lesions in the anteroposterior axis compared to adults, with statistically significant differences. PC usually are multiple and predominate in middle, posterior and peripheral portions of the lungs. Subpleural sparing and fissure crossing seems to be infrequent and have similar frequencies between children and adults. Although, there are differences between these age groups, as younger people tend to have more consolidation and diffuse opacities in the anteroposterior axis than older ones.

Abstract
BACKGROUND Current guidelines emphasize the indispensability of high-quality chest compression for improving survival in patients who experience out-of-hospital cardiac arrest (OHCA). However, chest compression can cause thoracic injuries that may contribute to poor prognosis; therefore, the purpose of this study is to identify the predictors of thoracic injuries and evaluate the association between thoracic injuries and prognosis.Methods and Results: Between June 2017 to July 2019, Utstein-style data on 384 consecutive adult patients who experienced non-traumatic OHCA and who were transferred to our hospital (Aso Iizuka Hospital) were collected. Each patient underwent a full-body computed tomography scan. Two-hundred and thirty-four patients (76%) had thoracic injuries (Group-T). The duration of chest compression was significantly longer in Group-T than in patients without thoracic injuries (Group-N; 43 vs. 32 min, respectively, P<0.001). Multivariate analysis revealed that older age and longer chest compression duration were predictors of thoracic injuries (odds ratios 1.03 and 1.07, respectively, P≤0.005). Among patients who achieved return of spontaneous circulation, Kaplan-Meier curves showed a significantly higher cumulative survival rate in Group-N than in Group-T at the 30-day follow up (log-rank test P=0.009). CONCLUSIONS Older age and longer chest compression duration were independent predictors of thoracic injuries due to chest compression in patients who experienced non-traumatic OHCA. Moreover, the presence of thoracic injuries was associated with worse short-term prognosis.

Abstract
Acute traumatic aortic injuries, which have substantial lethal outcomes at the time of admission, are fatal in 80% to 90% of cases. These injuries are relatively rare and have nonspecific clinical presentations. Radiologists and emergency physicians need to identify the radiological signs of acute traumatic aortic injury and differentiate them from common imaging errors to ensure accurate diagnosis and determine appropriate management protocols. In combination with image-guided interventions, advances in cross-sectional imaging have enabled nonsurgical management of acute traumatic aortic injuries. Timely and precise diagnoses of these injuries following prompt treatment are essential as up to 90% of patients presenting at the hospital can undergo early repair.

Abstract
OBJECTIVES Trauma chest radiographs may contain subtle and time-critical pathology. Artificial intelligence (AI) may aid in accurate reporting, timely identification and worklist prioritisation. However, few AI programs have been externally validated. This study aimed to evaluate the performance of a commercially available deep convolutional neural network - Annalise CXR V1.2 (Annalise.ai) - for detection of traumatic injuries on supine chest radiographs. METHODS Chest radiographs with a CT performed within 24 h in the setting of trauma were retrospectively identified at a level one adult trauma centre between January 2009 and June 2019. Annalise.ai assessment of the chest radiograph was compared to the radiologist report of the chest radiograph. Contemporaneous CT report was taken as the ground truth. Agreement with CT was measured using Cohen's κ and sensitivity/specificity for both AI and radiologists were calculated. RESULTS There were 1404 cases identified with a median age of 52 (IQR 33-69) years, 949 males. AI demonstrated superior performance compared to radiologists in identifying pneumothorax (p = 0.007) and segmental collapse (p = 0.012) on chest radiograph. Radiologists performed better than AI for clavicle fracture (p = 0.002), humerus fracture (p < 0.0015) and scapula fracture (p = 0.014). No statistical difference was found for identification of rib fractures and pneumomediastinum. CONCLUSION The evaluated AI performed comparably to radiologists in interpreting chest radiographs. Further evaluation of this AI program has the potential to enable it to be safely incorporated in clinical processes. ADVANCES IN KNOWLEDGE Clinically useful AI programs represent promising decision support tools.

Abstract
In the setting of acute trauma where identification of critical injuries is time-sensitive, a portable chest radiograph is broadly accepted as an initial diagnostic test for identifying benign and life-threatening pathologies and guiding further imaging and interventions. This article describes chest radiographic findings associated with various injuries resulting from blunt chest trauma and compares the efficacy of the chest radiograph in these settings with computed tomography (CT). Common chest radiographic findings in blunt thoracic injuries will be reviewed to improve radiologic identification, expedite management, and improve trauma morbidity and mortality. This article discusses demographic information, mechanism of specific injuries, common imaging findings, imaging pearls, and pitfalls and exhibits several classic imaging findings in blunt chest trauma. Thoracic structures commonly injured in blunt trauma that will be discussed in this article include vasculature structures (aortic trauma), the heart (cardiac contusion, pericardial effusion), the esophagus (esophageal perforation), pleural space and airways (pneumothorax, hemothorax, bronchial injury), lungs (pulmonary contusion), the diaphragm (diaphragmatic rupture), and the chest wall (flail chest). Chest radiography plays an important role in the initial evaluation of blunt chest trauma. While CT imaging has a higher sensitivity than chest radiography, it remains a valuable tool due to its ability to provide rapid diagnostic information in time-sensitive trauma situations and is ubiquitously available in the trauma bay. Familiarity with the gamut of injuries that may occur as well as identification of the associated chest radiograph findings can aid in timely diagnoses and prompt management in the setting of acute blunt chest trauma.

Abstract
INTRODUCTION This study aimed to investigate the specific effects of subcutaneous adipose tissue thickness (SATT) on trauma-related injury (TRI) development in patients with low-energy isolated blunt thoracic trauma. PATIENTS AND METHODS This prospective observational study was performed between March 2018-March 2019. Patients admitted to our hospital because of blunt thoracic trauma were enrolled. SATT in axial CT images of the thorax was measured using the four anatomically designated localizations. Patients were analyzed in terms of demographic data, BMI, comorbid diseases, causes of injury, vital parameters, visual analog scale, trauma score, injury type, treatment, and hospitalization. A poor clinical outcome was defined as the development of a TRI. RESULTS The study group consisted of 152 patients (43 female, 109 male). The mean age was 49 ± 19.1 years. There was a positive linear association between the BMI and SATT for all the patients in the study. TRI frequency was higher in the low-SATT subgroup than in the high-SATT group (p < 0.001). BMI and mean SATT values were related to a poor logistic regression analysis outcome (p < 0.01). Being in the low-BMI subgroup was a risk factor for TRI development (p < 0.01; OR:0.23;95% CI:0.08-0.61). CONCLUSION We found that a low SATT and BMI were related to a poor clinical outcome in our study group. It is essential to carefully examine these patients in detail, even in low-energy trauma. Subcutaneous tissue over the thorax serves as a protective shield for other thoracic structures in patients with LEBTT.

Abstract
BACKGROUND Isolated sternal fracture, a benign injury, has been increasing in the pan-scan era, although one-third of patients with sternal fracture still has trouble with concomitant injury. The differentiation of these two entities is important to optimize patient management. PURPOSE To evaluate correlation between retrosternal hematoma and concomitant injury in patients with sternal fracture and to identify predicting factors for concomitant injury in sternal fracture. MATERIAL AND METHODS A total of 139 patients (84 men; mean age = 54.9 ± 15.3 years) with traumatic sternal fracture were enrolled in this study. We reviewed medical charts and multiplanar computed tomography (CT) images to evaluate cause, location, and degree of sternal fracture, retrosternal hematoma, and concomitant injury. Univariate and multivariate analysis were used to identify variables that were associated with concomitant injury. RESULTS Concomitant injury on chest CT was observed in 85 patients with sternal fracture. Of the patients, 98 (70.5%) were accompanied by retrosternal hematoma. Multivariate analysis revealed that retrosternal hematoma (odds ratio [OR] = 5.350; P < 0.001), manubrium fracture (OR = 6.848; P = 0.015), and motor vehicle accident (OR = 0.342; P = 0.015) were significantly associated with sternal fracture with concomitant injury. CONCLUSION Manubrium fracture and retrosternal hematoma portend a high risk of concomitant injury and indicate the need for further clinical and radiologic work-up.

Abstract
Background Coronavirus (COVID-19) pneumonia emerged in Wuhan, China, in December 2019. It was highly contagious spreading all over the world, with a rapid increase in the number of deaths. The reported cases have reached more than 14 million with more than 600,000 deaths around the world. So, the pandemic of COVID-19 became a surpassing healthcare crisis with an intensive load on the healthcare resources. In this study, the aim was to differentiate COVID-19 pneumonia from its mimickers as atypical infection, interstitial lung diseases, and eosinophilic lung diseases based on CT, clinical, and laboratory findings. Results This retrospective study included 260 patients, of which 220 were confirmed as COVID-19 positive by two repeated RT-PCR test and 40 were classified as non-COVID by two repeated negative RT-PCR test or identification of other pathogens, other relevant histories, or clinical findings. In this study, 158 patients were male (60.7 %) and 102 patients were female (39.3%). There was 60.9% of the COVID-19 group were male and 39.1% were female. Patients in the non-COVID group were significantly older (the mean age was 46.4) than those in the confirmed COVID-19 group (35.2y). In the COVID-19 group, there was exposure history to positive cases in 84.1% while positive exposure history was 20% in the non-COVID group. Conclusion The spectrum of CT imaging findings in COVID-19 pneumonia is wide that could be contributed by many other diseases making the interpretation of chest CTs nowadays challenging to differentiate between different diseases having the same signs and act as deceiving simulators in the era of COVID-19.

Abstract
Blunt cardiac injury (BCI), defined as an injury to the heart from blunt force trauma, ranges from minor to life-threatening. The majority of BCIs are due to motor vehicle accidents; however, injuries caused by falls, blasts, and sports-related injuries also can be sources of BCI. A significant proportion of patients with BCI do not survive long enough to receive medical care, succumbing to their injuries at the scene of the accident. Additionally, patients with blunt trauma often have coexisting injuries (brain, spine, orthopedic) that can obscure the clinical picture; therefore, a high degree of suspicion often is required to diagnose BCI. Traditionally, hemodynamically stable injuries suspicious for BCI have been evaluated with electrocardiograms and chest radiographs, whereas hemodynamically unstable BCIs have received operative intervention. More recently, computed tomography and echocardiography increasingly have been utilized to identify injuries more rapidly in hemodynamically unstable patients. Transesophageal echocardiography can play an important role in the diagnosis and management of several BCIs that require operative repair. Close communication with the surgical team and access to blood products for potentially massive transfusion also play key roles in maintaining hemodynamic stability. With proper surgical and anesthetic care, survival in cases involving urgent cardiac repair can reach 66%-to-75%. This narrative review focuses on the types of cardiac injuries that are caused by blunt chest trauma, the modalities and techniques currently used to diagnose BCI, and the perioperative management of injuries that require surgical correction.

Abstract
Trauma is the leading cause of death among individuals under 40 years of age, and pulmonary trauma is common in high-impact injuries. Unlike most other organs, the lung is elastic and distensible, with a physiologic capacity to withstand significant changes in contour and volume. The most common types of lung parenchymal injury are contusions, lacerations, and hematomas, each having characteristic imaging appearances. A less common type of lung injury is herniation. Chest radiography is often the first-line imaging modality performed in the assessment of the acutely injured patient, although there are inherent limitations in the use of this modality in trauma. CT images are more accurate for the assessment of the nature and extent of pulmonary injury than the single-view anteroposterior chest radiograph that is typically obtained in the trauma bay. However, the primary limitations of CT concern the need to transport the patient to the CT scanner and a longer processing time. The American Association for the Surgery of Trauma has established the most widely used grading scale to describe lung injury, which serves to communicate severity, guide management, and provide useful prognostic factors in a systematic fashion. The authors provide an in-depth exploration of the most common types of pulmonary parenchymal, pleural, and airway injuries. Injury grading, patient management, and potential complications of pulmonary injury are also discussed. ©RSNA, 2021.

Abstract
The subpleural sparing pattern is a common finding on computed tomography (CT) of the lungs. It comprises of pulmonary opacities sparing the lung peripheries, typically 1cm and less from the pleural surface. This finding has a variety of causes, including idiopathic, inflammatory, infectious, inhalational, cardiac, traumatic, and bleeding disorders. Specific disorders that can cause subpleural sparing patterns include nonspecific interstitial pneumonia (NSIP), organizing pneumonia (OP), pulmonary alveolar proteinosis (PAP), diffuse alveolar hemorrhage (DAH), vaping-associated lung injury (VALI), cracked lung, pulmonary edema, pneumocystis jirovecii pneumonia (PJP), pulmonary contusion, and more recently, Coronavirus disease 2019 (COVID-19) pneumonia. Knowledge of the many etiologies of this pattern can be useful in preventing diagnostic errors. In addition, although the etiology of subpleural sparing pattern is frequently indistinguishable during an initial radiologic evaluation, the differences in location of opacities in the lungs, as well as the presence of additional radiologic findings, patient history, and clinical presentation, can often be useful to suggest the appropriate diagnosis. We did a comprehensive search on Pubmed and Google Scholar database using keywords of "subpleural sparing," "peripheral sparing," "sparing of peripheries," "CT chest," "chest imaging," and "pulmonary disease." This review aims to describe the primary differential diagnosis of subpleural sparing pattern seen on chest imaging with a strong emphasis on clinical and radiographic findings. We also discuss the pathogenesis and essential clues that are crucial to narrow the differential diagnosis.

Abstract
Physical traumas are tragic and multifaceted injuries that suddenly threaten life. Although it is the third most common cause of death in all age groups, one out of four trauma patients die due to thoracic injury or its complications. Blunt injuries constitute the majority of chest trauma. This indicates the importance of chest trauma among all traumas. Blunt chest trauma is usually caused by motor vehicle accident, falling from height, blunt instrument injury and physical assault. As a result of chest trauma, many injuries may occur, such as pulmonary injuries, and these require urgent intervention. Chest wall and pulmonary injuries range from rib fractures to flail chest, pneumothorax to hemothorax and pulmonary contusion to tracheobronchial injuries. Following these injuries, patients may present with a simple dyspnea or even respiratory arrest. For such patient, it is important to understand the treatment logic and to take a multidisciplinary approach to treat the pulmonary and chest wall injuries. This is because only 10% of thoracic trauma patients require surgical operation and the remaining 90% can be treated with simple methods such as appropriate airway, oxygen support, maneuvers, volume support and tube thoracostomy. Adequate pain control in chest trauma is sometimes the most basic and best treatment. With definite diagnosis, the morbidity and mortality can be significantly reduced by simple treatment methods.

Abstract
In this study, we describe the computed tomography (CT) features of pulmonary laceration in a study population, which included 364 client-owned dogs that underwent CT examination for thoracic trauma, and compared the characteristics and outcomes of dogs with and without CT evidence of pulmonary laceration. Lung laceration occurred in 46/364 dogs with thoracic trauma (prevalence 12.6%). Dogs with lung laceration were significantly younger than dogs in the control group (median 42 months (interquartile range (IQR) 52.3) and 62 months (IQR 86.1), respectively; p = 0.02). Dogs with lung laceration were significantly heavier than dogs without laceration (median 20.8 kg (IQR 23.3) and median 8.7 kg (IQR 12.4 kg), respectively p < 0.0001). When comparing groups of dogs with thoracic trauma with and without lung laceration, the frequency of high-energy motor vehicle accident trauma was more elevated in dogs with lung laceration than in the control group. No significant differences were observed between groups regarding tge frequency and length of hospitalization and 30-day mortality. Similar to the human classification scheme, four CT patterns are described in dogs in this study: Type 1, large pulmonary laceration located deeply in the pulmonary parenchyma or around an interlobar fissure; Type 2, laceration occurring in the paraspinal lung parenchyma, not associated with vertebral fracture; Type 3, subpleural lung laceration intimately associated with an adjacent rib or vertebral fracture; Type 4, subpleural lesions not associated with rib fractures. Complications were seen in 2/46 dogs and included lung abscess and collapse.

Abstract
OBJECTIVES To describe the incidence of and risk factors for vascular injury associated with P-SCD. METHODS We used data from the HCUP-NIS from 2015 to 2016 and defined a cohort of patients with sternoclavicular dislocation (SCD) using ICD-10-CM diagnosis codes. We further isolated a subset with P-SCD. We describe the incidence of thoracic vascular injury, demographics, and injury severity score in this cohort. RESULTS Of an estimated 550 patients who had SCD, 140 (25%) were identified as having a P-SCD. No vascular injuries occurred in the P-SCD cohort. Among all patients with SCD, <2% of patients had a vascular injury, all of whom had an injury severity score ≥15, independent of the vascular injury itself. Among patients with an isolated P-SCD injury (55), overall length of stay was 1.8 days and total charges averaged $29,724.45. There was no mortality among patients with isolated P-SCD. CONCLUSIONS Here, we report no vascular injuries in the largest known series of P-SCD. Among all patients with SCD, vascular injury was rare, occurring only in severely polytraumatized patients. The recommendation for routine involvement of cardiothoracic surgeons in all cases of P-SCD should be re-examined. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
ABSTRACT Objective: to perform an external validation of two clinical decision instruments (DIs) - Chest CT-All and Chest CT-Major - in a cohort of patients with blunt chest trauma undergoing chest CT scanning at a trauma referral center, and determine if these DIs are safe options for selective ordering of chest CT scans in patients with blunt chest trauma admitted to emergency units. Methods: cross-sectional study of patients with blunt chest trauma undergoing chest CT scanning over a period of 11 months. Chest CT reports were cross-checked with the patients’ electronic medical record data. The sensitivity and specificity of both instruments were calculated. Results: the study included 764 patients. The Chest CT-All DI showed 100% sensitivity for all injuries and specificity values of 33.6% for injuries of major clinical significance and 40.4% for any lesion. The Chest CT-Major DI had sensitivity of 100% for injuries of major clinical significance, which decreased to 98.6% for any lesions, and specificity values of 37.4% for injuries of major clinical significance and 44.6% for all lesions. Conclusion: both clinical DIs validated in this study showed adequate sensitivity to detect chest injuries on CT and can be safely used to forego chest CT evaluation in patients without any of the criteria that define each DI. Had the Chest CT-All and Chest CT-Major DIs been applied in this cohort, the number of CT scans performed would have decreased by 23.1% and 24.6%, respectively, resulting in cost reduction and avoiding unnecessary radiation exposure.

Abstract
Several imaging findings of thoracic diseases have been referred-on chest radiographs or CT scans-to signs, symbols, or naturalistic images. Most of these imaging findings include the air bronchogram sign, the air crescent sign, the arcade-like sign, the atoll sign, the cheerios sign, the crazy paving appearance, the comet-tail sign, the darkus bronchus sign, the doughnut sign, the pattern of eggshell calcifications, the feeding vessel sign, the finger-in-gloove sign, the galaxy sign, the ginkgo leaf sign, the Golden-S sign, the halo sign, the headcheese sign, the honeycombing appearance, the interface sign, the knuckle sign, the monod sign, the mosaic attenuation, the Oreo-cookie sign, the polo-mint sign, the presence of popcorn calcifications, the positive bronchus sign, the railway track appearance, the scimitar sign, the signet ring sign, the snowstorm sign, the sunburst sign, the tree-in-bud distribution, and the tram truck line appearance. These associations are very helpful for radiologists and non-radiologists and increase learning and assimilation of concepts.Therefore, the aim of this pictorial review is to highlight the main thoracic imaging findings that may be associated with signs, symbols, or naturalistic images: an "iconographic" glossary of terms used for thoracic imaging is reproduced-placing side by side radiological features and naturalistic figures, symbols, and schematic drawings.

Abstract
The thoracic inlet is located at the crossroads between imaging of the neck and chest. It represents an important anatomic landmark, serving as the central conducting pathway for many vital structures extending from the neck into the chest and vice versa. Many important body systems are located within this region, including the enteric, respiratory, vascular, lymphatic, neurologic, and endocrine systems. A detailed examination of this region is essential when reviewing neck and thoracic imaging. This article will discuss the normal anatomic boundaries of the thoracic inlet and present an image-rich systematic discussion of the non-neoplastic pathology that can occur in this region. The neoplastic pathology of the thoracic inlet will be covered in a companion article.

Incidence and risk factors of pulmonary atelectasis in mechanically ventilated trauma patients in ICU: a prospective study. INT J EVID-BASED HEA 2019; 17:44-52. [PMID: 30113349 DOI: 10.1097/xeb.0000000000000150] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
AIM The aim of the study was to obtain information about the incidence and risk factors for pulmonary atelectasis in mechanically ventilated patients in the trauma ICU (TMICU). Pulmonary atelectasis is a common complication leading to serious lung dysfunction in patients in the TMICU and early identification of patients at risk is important for their effective management. METHODS All trauma patients admitted to the TMICU with mechanical ventilation for more than 1 day were included in a prospective 12-month study. Pulmonary atelectasis was diagnosed from chest radiographs by a critical care doctor and radiologist. RESULTS A total of 405 trauma patients were identified and data from 338 patients analyzed showing the incidence of pulmonary atelectasis to be 14%. Multivariate analysis revealed significant risk factors to be chest injury with an adjusted odds ratio (AOR) of 102.8, abdominal injury (AOR: 4.6), surgical intervention (AOR: 8.4), comorbidity (AOR: 13.7), Acute Physiology and Chronic Health Evaluation II score (APACHE II) of at least 15 (AOR: 4.8), sedation of at least 7 days (AOR: 7.5) and mechanical ventilation of at least 9 days (AOR: 3.43). Patients with chronic pulmonary disease tended to have higher risk for pulmonary atelectasis (AOR: 8.8). Patients with pulmonary atelectasis had longer stays in TMICU (P < 0.001) and higher mortality (P = 0.013). CONCLUSION The incidence of pulmonary atelectasis in TMICU in Thailand is comparable with that of the developed world. Pulmonary atelectasis is particularly associated with chest trauma, whereas abdominal injury, APACHE II of at least 15, surgery, comorbidity and prolonged mechanical ventilation are also significant risk factors. Early interventions to prevent or treat pulmonary atelectasis in these patients may improve outcome and shorten their stay in the TMICU and hospital.

Abstract
Traumatic pulmonary pseudocysts following non-penetrating blunt thoracic trauma is a well-described phenomenon in the human literature, while in veterinary medicine, this disease process is rarely reported and poorly described in the current literature available. This case report describes a 1.5-year-old male castrated Labrador retriever with findings of pulmonary cysts following a road traffic accident. The goal of this report is to expound upon the pathophysiology, diagnosis, and treatment of this disease process in the veterinary field.

Abstract
There were few case reports discuss about iatrogenic chest wall hematoma. Although it is rare life threatening, it still can result in significant morbidity. A 68-year-old woman with histories of end-stage renal disease under regular hemodialysis and congestive heart failure was sent to our emergency department because of progression of ecchymosis over the anterior chest wall a few hours after hemodialysis. The right subclavian hemodialysis catheter was inserted for hemodialysis on the same day. She did not have a history of bleeding disorders and was not taking any antiplatelet or anticoagulant agents. Additionally, she had no recent trauma episodes. Physical examination revealed a large ecchymosis over the anterior right chest wall with swelling and tenderness. Blood examination showed no specific finding. Contrast-enhanced computed tomography of the chest revealed a hyperdense lesion with extravasation over the right chest wall, suggesting the presence of a hematoma with active bleeding. Local compression was applied. However, hematoma expansion was still noted. Therefore, we consulted a thoracic surgeon concerning surgical intervention. During the operation, active bleeding of the intramuscular arterial branch of the right pectoralis major was encountered. After surgical repair, no more bleeding was noted. It is important to confirm the possible cause of chest wall hematoma. Treating the underlying disease and discontinuing anticoagulation and antiplatelet agents should be considered. For iatrogenic chest wall hematoma, bleeding control should be the priority. Contrast-enhanced computed tomography could be arranged if there are no contraindications.

Abstract
There are various neoplasms and tumour-like conditions of the pleura. Mesothelioma is perhaps the most widely recognised; however, there are many others that are more common and should be considered. Understanding the similarities and differences can be helpful in managing the patient with a newly found pleural lesion. We will discuss clinical symptoms at presentation and describe the imaging findings associated with these tumours, starting with conventional radiology, and correlating with computed tomography and combined positron-emission tomography (PET)/computed tomography (CT). Finally, imaging characteristics that help differentiation between the benign and malignant varieties will be reviewed.

Abstract
BACKGROUND Scapular fractures have been traditionally taught to be associated with significant injuries and major morbidity. As we demonstrated with sternal fracture, pulmonary contusion, and rib fracture, increased chest computed tomography (CT) utilization and head-to-pelvis CT (pan-scan) protocols in blunt trauma evaluation, however, may diagnose minor, clinically irrelevant scapular fractures, possibly rendering previous teachings obsolete. OBJECTIVES The objectives were to determine the 1) percentages of scapular fractures seen on chest CT only (SOCTO) versus seen on both chest x-ray (CXR) and CT and of isolated scapular fracture (scapular fracture without other thoracic injuries); 2) frequencies of associated thoracic injury with scapular fracture; and 3) proportion of patients admitted, mortality, hospital length of stay, and injury severity scores (ISS), comparing four patient groups: scapular fracture, nonscapular fracture, scapular fracture SOCTO, and isolated scapular fracture. METHODS We conducted a preplanned analysis of patients prospectively enrolled in the NEXUS Chest CT study at nine Level I trauma centers with the following inclusion criteria: age > 14 years, blunt trauma within 6 hours of ED presentation, and receiving chest imaging during ED trauma evaluation. RESULTS Of 11,477 subjects, 4,501 (39.2%) patients who had both CXR and chest CT and 2.7% of these had scapular fractures; 60.3% of these were SOCTO and 23 (19.0%) were isolated scapular fracture. The most commonly associated thoracic injuries were rib fracture, pulmonary contusion, pneumothorax, and thoracic spine fracture and all injuries were more common in scapular fracture patients than nonscapular fracture patients. Although scapular fracture patients had higher admission rates (86.8% vs. 47.4%; difference in proportions = 39.4% [95% confidence interval {CI} = 32.8% to 44.1%]), ISS (21 vs. 5), and length of stay (9.2 days vs. 5.6 days; mean difference = 3.4 days [95% CI = 2.1 to 4.7 days]) than patients without scapular fracture, their hospital mortality was not significantly different (5.6% vs. 3.0%; difference in proportions = 2.6% [95% CI = -8.2% to 0.3%]; unadjusted odds ratio = 1.9 [95% CI = 0.9 to 4.2]). Patients with scapular fracture SOCTO and isolated scapular fracture had higher admission rates and median ISS than nonscapular fracture patients, but their mortality was similar. CONCLUSIONS Under current blunt trauma imaging protocols that commonly include chest CT, most scapular fractures are SOCTO and most are associated with other thoracic injuries. Although patients with scapular fracture SOCTO and isolated scapular fracture have higher admission rates and ISS than nonscapular fracture patients, their hospital mortality is similar.

Abstract
BACKGROUND In the general population with blunt chest trauma, pulmonary contusions (PCs) are commonly identified. However, there is limited research in the elderly. We sought to evaluate the incidence and outcomes of PCs in elderly blunt trauma admissions. METHODS We retrospectively reviewed the trauma registry at a level I trauma center for all blunt thoracic trauma patients aged ≥65 y, who were admitted between 2007 and 2015. The medical records of PC patients were reviewed. RESULTS There were 956 admissions with blunt thoracic trauma; of which 778 had no pulmonary contusion (NO) and 178 had PC. The major mechanisms of injury were falls (58.7% NO, 39.3% PC, P <0.001) and motor vehicle crash/motor cycle crash (35.6% NO, 51.7% PC, P <0.001). Rib fractures were present in 79.8% of PC and 73.8% of NO patients, P = 0.1. PC patients more often had serious (AIS ≥3) head/neck (30.3% versus 20.6%, P <0.001), abdomen (12.4% versus 6.6%, P <0.001), and extremity injuries (20.8% versus 11.4%, P <0.001). Complication (46.1% PC versus 26.6% NO, P <0.001) and mortality (14.0% PC versus 6.2% NO, P = 0.0003) rates were higher in PC patients. On multivariate logistic regression analyses, PC presence was significantly associated with mechanical ventilation (odds ratio 2.5), intensive care unit admission (odds ratio 2.3), and mortality (odds ratio 1.9). CONCLUSIONS Over 18.6% of elderly blunt thoracic trauma patients sustained PC, despite an often low energy mechanism of injury. The presence of a PC should prompt investigation for other serious intrathoracic and extrathoracic injuries. PC presence is associated with substantial morbidity and mortality.

Pneumomediastinum and pneumopericardium following blunt thoracic trauma: much ado about nothing? Eur J Trauma Emerg Surg 2018; 45:927-931. [PMID: 29687275 DOI: 10.1007/s00068-018-0960-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Accepted: 04/18/2018] [Indexed: 12/27/2022]
Abstract
PURPOSE Pneumomediastinum is the hallmark of intrathoracic aerodigestive trauma, but rare following blunt injury. AIM review of blunt thoracic trauma (BTC) for the incidence and outcome of patients with pneumomediastinum or pneumopericardium (PM/PC) on Computerised Tomographic scanning. METHODS Admissions to the level I trauma ICU at IALCH, Durban, ZA following BTC from April 2007 to March 2014. Patients with Chest-CT-scan were analysed. Variables included age, sex, mechanism of injury, and Injury Severity Score (ISS). Specific injury patterns: isolated thoracic trauma, flail chest, bilateral injury and presence of haemothorax or pneumothorax were analysed. RESULTS Three hundred and eighty-nine patients were included. Males (70.9%) accounted for the majority of patients. The median Injury Severity Score was 32 (IQR 24-41). Motor vehicle collisions accounted for 94% of injury mechanisms. Twenty-three (5.9%) were identified with pneumomediastinum, 6 (1.5%) with both pneumomediastinum and pneumopericardium, and 1 (0.2%) with isolated pneumopericardium. No patient required surgery for thoracic trauma. Increasing age (p < 0.001) and a flail chest (p = 0.005) were significant associations. The mortality rate was almost identical in those with or without air within the mediastinum. No patient died from a missed mediastinal aero-digestive injury. CONCLUSION The presence of PM/PC following BTC is incidental and benign. Increased injury severity with a flail chest is associated with a significant increase in the presence of free gas within the mediastinum. In the absence of complications, no obvious injury to the intrathoracic aero-digestive tract on CT scanning, and no difference in mortality, a conservative management policy is warranted.
