Abstract
BACKGROUND While chest X-ray (CXR) is an efficient tool for expeditious detection of life-threatening injury, chest computed tomography (CCT) is more sensitive albeit with added time, cost, and radiation. Thus far, there is limited evidence and lack of consensus on the best imaging practices. We sought to determine the association between imaging modality and outcomes in isolated blunt thoracic trauma. METHODS The 2017-2020 TQIP database was queried for adult patients who sustained isolated blunt chest trauma and underwent chest imaging within 24 hours of admission. Patients who underwent CCT were 2:1 propensity-score-matched to those who underwent CXR. The primary outcome was mortality, and the secondary outcomes were hospital and ICU length of stay (LOS), ICU admission, need for and days requiring mechanical ventilation, complications, and discharge location. RESULTS Propensity score matching yielded 17 716 patients with CCT and 8861 with CXR. While bivariate analysis showed lower 24-hr (CCT .2% vs CXR .4%, P = .0015) and in-hospital mortality (CCT 1.2% vs CXR 1.5%, P = .0454) in the CCT group, there was no difference in survival probability between groups (P = .1045). A higher percentage of CCT patients were admitted to the ICU (CCT 26.9% vs CXR 21.9%, P < .0001) and discharged to rehab (CCT .8% vs CXR .5%, P = .0178). DISCUSSION CT offers no survival benefit over CXR in isolated blunt thoracic trauma. While CCT should be considered if clinically unclear, CXR likely suffices as an initial screening tool. These findings facilitate optimal resource allocation in constrained environments.

[PMID: 38354687 DOI: 10.1016/j.injury.2024.111404] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 01/23/2024] [Accepted: 01/27/2024] [Indexed: 02/16/2024]
Abstract
INTRODUCTION Fractures of the ribs and sternum are associated with significant morbidity and mortality. Characterization of the injury burden across England is necessary to inform and evaluate developments in trauma care and infrastructure, however is yet to be comprehensively undertaken. Therefore, the aim of this study was to describe trends in the incidence of sternal and rib fractures across England between 1990 and 2019. MATERIALS AND METHODS Age-standardised incidence rates (ASIRs) for rib and sternal fractures in males and females were extracted from the 2019 Global Burden of Disease (GBD) study by all causes, falls and road traffic collisions for 9 sub-regions of England. Temporal trends within the study period were analysed using Joinpoint regression analysis. RESULTS The overall ASIRs in England in 2019 were 30.34/100,000 and 46.02/100,000 for females and males, respectively. Between 1990 and 2019, the estimated overall percentage change across England was +0.20 % among females and -7.05 % among males. A statistically significant increase in ASIR was observed in all 9 sub-regions of England among females from 2014-2019 (p<0.001). Among males, a statistically significant increase in ASIR was observed in 7 of the 9 regions from 2014-2019 (p<0.001) and in the remaining 2 regions from 2015-2019 (p<0.001). DISCUSSION Increasing ASIRs of rib and sternal fractures were observed among females and decreasing ASIRs among males, with overall ASIRs higher among males. Developments in trauma infrastructure and associated variations in diagnostic and management strategies over the observation period likely contribute to changes in the national injury burden. The findings are suggestive of the importance of ongoing financial investment in trauma infrastructure and of clear clinical guidelines to manage an increasing national injury burden.

Abstract
OBJECTIVES The aim of the study was to describe clinical examination and thoracic CT (TCT) findings in cats after trauma, and to identify physical examination findings associated with both abnormalities on TCT and the need for therapeutic interventions. METHODS A multicentre, retrospective, observational study was conducted. Cats admitted to the participating hospitals with a history of blunt trauma and that underwent TCT were eligible. Data were collected on signalment, history, physical examination, TCT findings and subsequent interventions. RESULTS In total, 137 cats were included. Road traffic accidents (RTAs) were the most frequently reported cause of trauma (69%). Tachypnoea (32%), pale mucous membranes (22%) and dyspnoea (20%) were the most common abnormal findings on thoracic examination. The most frequently identified thoracic pathologies on TCT were atelectasis (34%), pulmonary contusions (33%), pneumothorax (29%) and pleural effusion (20%). Thoracocentesis was the most commonly performed intervention (12%), followed by chest drain placement (7%). A total of 45 (33%) cats had no physical examination abnormalities but did have abnormalities detected on TCT; six of these cats required interventions. Increasing numbers of thoracic abnormalities on clinical examination were associated with increasing likelihood of having abnormal findings on TCT (odds ratio [OR] 2.04, 95% confidence interval [CI] 1.21-3.44, P = 0.008) and of requiring an intervention (OR 1.82, 95% CI 1.32-2.51, P <0.001). CONCLUSIONS AND RELEVANCE RTAs were the most common reported cause of blunt trauma. Atelectasis, pulmonary contusions and pneumothorax were the most common abnormalities identified on TCT, and thoracic drainage was the most utilised intervention. TCT may be useful in identifying cats with normal thoracic physical examination findings that have significant thoracic pathology, and a high number of abnormal findings on thoracic examination should raise suspicion for both minor and major thoracic pathology. The results of this study can be used to assist in selecting appropriate cases for TCT after blunt trauma.

Abstract
OBJECTIVE To determine the value of ordering a routine chest CT (CCT) in patients with blunt trauma presenting to the emergency department with a high GCS and low ISS, we retrospectively collected patient data including CT scan results, when physical examination and initial chest X-ray were normal in the trauma bay area. METHODS A retrospective data collection of 901 consecutive blunt trauma patients seen in the ED between 2017 and 2019 was analyzed. Data included physical examination, age, gender, current use of anticoagulation therapy, comorbid conditions, as well as the result of radiologic images, hospital length of stay, surgical intervention, and mortality. The patients were divided into two groups: group one (patients with negative physical examination; chest x-ray and CT) and group 2 (negative physical examination, positive or negative chest x-ray, and positive CT). Statistical analysis was performed using student's t-test and chi-square test. RESULTS Of the 901 patients there were 489 (54%) males and 412 (46%) females with a mean age of 56 years. There were 461 patients who had a physical examination, chest x-ray, abdominal and CCT done. Group one included 442 (96%) patients, with negative physical examination, negative chest X-ray and CT scan. In group 2, 19 (4%) patients who had positive CT and or chest x-ray. Both groups were similar in GCS and ISS. Of the 19 patients, sixteen patients had a positive CCT, and thirteen of those had a positive chest x-ray. In the three patients who had negative physical examination and chest x-ray, the CT findings included one with a nondisplaced 10th rib fracture and two patients with osteoporotic compression fractures of dorsal vertebrae. The rate of both chest x-ray and CCT being positive among a group of screened patients was 16% (3/19) and the rate of a negative chest x-ray but positive CT was 16% (3/19). The odds ratio between the two outcomes was one. CONCLUSION In blunt trauma patients presenting to the ED with a high GCS and low ISS score, when initial physical examination and chest x-ray are negative, routine CCT is of little value.

Abstract
Introduction Chest imaging plays a prominent role in the assessment of patients with blunt trauma. Selection of the right approach at the right time is fundamental in the management of patients with blunt chest trauma.[1] A reliable, economic, bedside, and rapidly accomplished screening test can be pivotal. [2]. Objective The aim of this study was to compare the accuracy of extended- focused assessment with sonography for trauma (E-FAST) to that of the National Emergency X-Radiography Utilisation Study (NEXUS) chest algorithm in detecting blunt chest injuries. Methods This descriptive cross-sectional study included 50 polytrauma patients with blunt chest trauma from the emergency centre of Suez Canal University Hospital. E-FAST and computed tomography (CT) were conducted, followed by reporting of NEXUS criteria for all patients. Blinding of the E-FAST performer and CT reporter were confirmed. The results of both the NEXUS algorithm and E-FAST were compared with CT chest results. Results The NEXUS algorithm had 100% sensitivity and 15.3% specificity, and E-FAST had 70% sensitivity and 96.7% specificity, in the detection of pneumothorax.In the detection of hemothorax, the sensitivity and specificity of the NEXUS algorithm were 90% and 7.5%, respectively, whereas E-FAST had a lower sensitivity of 80% and a higher specificity of 97.5%. Conclusion E-FAST is highly specific for the detection of hemothorax, pneumothorax, and chest injuries compared with the NEXUS chest algorithm, which demonstrated the lowest specificity. However, the NEXUS chest algorithm showed a higher sensitivity than E-FAST and hence can be used effectively to rule out thoracic injury.

The sensitivity of chest X-ray (CXR) for the detection of significant thoracic injury in children exposed to blast. Injury 2022; 54:1292-1296. [PMID: 36539310 DOI: 10.1016/j.injury.2022.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 11/22/2022] [Accepted: 12/01/2022] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Thoracic trauma is an important cause of morbidity and mortality in children exposed to blast and early recognition of these injuries is vital. While numerous studies have investigated the sensitivity of chest X-ray (CXR) for the detection of chest injury in blunt trauma, none have evaluated its performance in paediatric blast injury. METHODS CXR and Computed Tomography (CT) thorax findings were compared for 105 children who were injured by blast and presented to the UK Role 3 Hospital, Camp Bastion, Helmand Province, during the recent conflict in Afghanistan from 2011 to 2013. CXR performance was evaluated compared to the 'gold standard' of CT for the detection of significant thoracic injuries, defined as pneumothorax, haemothorax, aortic or great vessel injury, 2 or more rib fractures, ruptured diaphragm, sternal fracture, penetrating fragments and pulmonary contusion or laceration. RESULTS The sensitivity of CXR for the detection of significant injuries was: pneumothorax 43%, haemothorax 40%, contusion 44%, laceration 100%, blast lung 80% and subdermal metallic fragments 75%. CXR missed all cases of diaphragm injury, ≥2 rib fractures, clavicle fracture and pleural effusion, although numbers of each were small. Specificity for CXR injury detection was 94% for contusion and 93% for fragment, and 100% otherwise. The sensitivity and specificity of CXR for identifying an abnormality that would prompt CT imaging was 72% (95% CI 55-85%) and 82% (95% CI 70-90%). CONCLUSIONS CXR has a poor sensitivity for the identification of significant thoracic injury in children exposed to blast. We argue that, given the challenge of clinical assessment of injured children and the potential for serious adverse consequences of missed thoracic injuries, there should be a low threshold for the use of CT chest in the evaluation of children exposed to blast.

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
Trauma remains a leading cause of death for all age groups, and nearly two-thirds of these individuals suffer thoracic trauma. Due to the various types of injuries, including vascular and nonvascular, interventional radiology plays a major role in the acute and chronic management of the thoracic trauma patient. Interventional radiologists are critical members in the multidisciplinary team focusing on treatment of the patient with thoracic injury. Through case presentations, this article will review the role of interventional radiology in the management of trauma patients suffering thoracic injuries.

Abstract
BACKGROUND Chest computed tomography (CT) scans are important for the management of rib fracture patients, especially when determining indications for surgical stabilization of rib fractures (SSRFs). Chest CTs describe the number, patterns, and severity of rib fracture displacement, driving patient management and SSRF indications. Literature is scarce comparing radiologist versus surgeon rib fracture description. We hypothesize there is significant discrepancy between how radiologists and surgeons describe rib fractures. METHODS This was an institutional review board-approved, retrospective study conducted at a Level I academic center from December 2016 to December 2017. Adult patients (≥18 years of age) suffering rib fractures with a CT chest where included. Basic demographics were obtained. Outcomes included the difference between radiologist versus surgeon description of rib fractures and differences in the number of fractures identified. Rib fracture description was based on current literature: 1, nondisplaced; 2, minimally displaced (<50% rib width); 3, severely displaced (≥50% rib width); 4, bicortically displaced; 5, other. Descriptive analysis was used for demographics and paired t test for statistical analysis. Significance was set at p = 0.05. RESULTS Four hundred and ten patients and 2,337 rib fractures were analyzed. Average age was 55.6(±20.6); 70.5% were male; median Injury Severity Score was 16 (interquartile range, 9-22) and chest Abbreviated Injury Scale score was 3 (interquartile range, 3-3). For all descriptive categories, radiologists consistently underappreciated the severity of rib fracture displacement compared with surgeon assessment and severity of displacement was not mentioned for 35% of rib fractures. The mean score provided by the radiologist was 1.58 (±0.63) versus 1.78 (±0.51) by the surgeon (p < 0.001). Radiologists missed 138 (5.9%) rib fractures on initial CT. The sensitivity of the radiologist to identify a severely displaced rib fracture was 54.9% with specificity of 79.9%. CONCLUSION Discrepancy exists between radiologist and surgeon regarding rib fracture description on chest CT as radiologists routinely underappreciate fracture severity. Surgeons need to evaluate CT scans themselves to appropriately decide management strategies and SSRF indications. LEVEL OF EVIDENCE Prognostic/Diagnostic Test, level III.

Abstract
BACKGROUND Pneumothorax (PTX) is defined as air in the pleural space and is classified as spontaneous or nonspontaneous (traumatic). Traumatic PTX is a common pathology identified in the emergency department. Traditional management calls for chest x-ray (CXR) diagnosis and large-bore tube thoracostomy, although recent literature supports the efficacy of lung ultrasound (US) and more conservative approaches. There is a paucity of cohesive literature on how to best manage the traumatic PTX. OBJECTIVE OF THE REVIEW This review aimed to describe current practices and future directions of traumatic PTX management. DISCUSSION Lung US has proven to be a potentially more useful tool in the detection of PTX in the trauma bay compared with CXR, and has the potential to become the new gold standard for diagnosing traumatic PTX. Computed tomography remains the ultimate gold standard, although in the setting of trauma, its utility lies more in confirming the presence and measuring the size of a PTX. The traditional mantra calling for large-bore chest tubes as first-line approaches to traumatic PTX is challenged by recent literature demonstrating pigtail catheters as equally efficacious alternatives. In patients with small or occult PTXs, even observation may be reasonable. CONCLUSIONS Modern management of the traumatic PTX is shifting toward use of US for diagnosis and more conservative management practices (smaller catheters or observation). Ultimately, this shift is favorable in reducing length of stay, development of complications, and pain in the trauma patient.

PURPOSE To examine the relationship between superficial lesions (such as bruises, hematomas, deep abrasions, and soft tissue emphysema) and internal post-traumatic injuries, assessed using whole-body computed tomography (WBCT), and to determine if these are valid markers for internal injuries. METHODS AND MATERIALS 250 patients who underwent WBCT emergency scans for suspected polytrauma were retrospectively analyzed after institutional review board approval of the study. The scans were carried out on patients who met the criteria for standard operating procedures for WBCT emergency scans. WBCT covering the entire head, neck, chest, and abdomen (including pelvis and proximal lower extremities) and at least one phase with intravenous contrast agent were included in the study. Initial analyses of immediate WBCT scans was carried out by a consultant radiologist and a radiological resident. The first reading focused on internal damage that needed immediate therapy. The second reading focused on a detailed analysis of the skin and subcutaneous tissue and their relation to internal injuries without the time pressure of an emergency setting, carried out by another experienced radiologist. All skin lesions and the degree of penetration and a comparison between the two readings were reported in tables. RESULTS Superficial lesion of the chest was detected in 19 patients, 17 of them had an internal injury of the thorax while only two patients, with hematoma of the chest wall, had no internal injuries. Skin and subcutaneous lesions of the chest had the strongest association with an internal injury. Skin lesions of the abdominal wall were observed in 30 patients. In only 11 cases, these lesions were correlated with internal injuries, such as fractures or active bleeding. 52 skin and subgaleal lesions of the scalp were observed. In 20 of these patients, an intracranial or internal injury was detected. In 3 patients, skin abrasions of the neck were present and in only one of them, this finding was associated with an internal injury. CONCLUSION Trauma patients whose history and clinical presentation meet the standard operating procedures for WBCT emergency scans and who present with a cutaneous lesion, especially at the neurocranium or chest wall, should be observed for internal injuries by WBCT. KEY POINTS · Presence or lack of a superficial injury of the abdominal wall is not a reliable predictive indication of any internal abdominal injury.. · Superficial lesions of the chest and the neurocranium require a CT scan.. · Superficial injuries of the chest wall had the strongest association with internal injuries..

Abstract
Background Flail chest and severely displaced rib fractures due to blunt trauma can be associated with intrathoracic injuries. At our institution, two thoracic surgeons perform all surgical stabilization of rib fractures (SSRF): one performs routine uniportal thoracoscopy (R-VATS) at the time of SSRF and the other for only select cases (S-VATS). In this pilot study, we hypothesized that R-VATS at the time of SSRF identifies and addresses intrathoracic injuries not seen on imaging and may impact patient outcomes. Methods A retrospective review of all patients who underwent SSRF from 2013–2019 at our institution was performed for severely displaced rib fractures or flail chest. Data collected included demographics, imaging results, treatment strategy, and operative findings. Results Ninety-nine patients underwent SSRF. Uniportal thoracoscopy was performed on 69% of these patients. When thoracoscopy was performed, 31 additional injuries were identified. R-VATS identified 23 additional intrathoracic findings at time of thoracoscopy not seen on CT scan compared to 8 findings in the S-VATS group (P=0.367). At 3 months follow-up, one empyema and one diaphragmatic hernia required reoperation—neither of which underwent thoracoscopy at time of SSRF. There were no differences in LOS, operative times, and overall mortality between the SSRF/thoracoscopy and SSRF only groups. Conclusions R-VATS at the time of SSRF did not identify a statistically significant greater number of occult intrathoracic injuries compared to S-VATS. R-VATS was not associated with increased operative time, LOS, and mortality. Further study is needed to determine if there is benefit to R-VATS in patients meeting requirements for rib fracture repair.

Detailed information gain and therapeutic impact of whole body computed tomography supplementary to conventional radiological diagnostics in blunt trauma emergency treatment: a consecutive trauma centre evaluation. Eur J Trauma Emerg Surg 2020; 48:921-931.

Abstract
Purpose The indication of whole body computed tomography (WBCT) in the emergency treatment of trauma is still under debate. We were interested in the detailed information gain obtained from WBCT following standardized conventional imaging (CI). Methods Prospective study including all emergency trauma centre patients examined by CI (focused assessment of sonography in trauma, chest and pelvic X-ray) followed by WBCT from 2011 to 2017. Radiology reports were compared per patient for defined body regions for number and severity of injuries (Abbreviated Injury Scale, AIS; Injury Severity Score, ISS), incidental findings and treatment consequences (Wilcoxon signed rank test, Spearman rho, Chi-square). Results 1271 trauma patients (ISS 11.3) were included in this study. WBCT detected more injury findings than CI in the equivalent body regions (1.8 vs. 0.6; p < 0.001). In 44.4% of cases at least one finding was missed by CI alone. Compared to WBCT, injury severity of specified body regions was underestimated by CI on average by an AIS of 1.9 (p < 0.001). In 22.0% of cases injury severity increased by an AIS ≥ 2 following WBCT. In 16.8% of patients additional injury findings resulted in a change of treatment (number needed to profit, NNP = 6 patients): NNP decreased from 25 for patients with an ISS < 7 up to nearly 2 for patients with an ISS > 25 at final evaluation, thereby demonstrating a significant improvement in the NNP with increasing ISS (rho = 0.33, p < 0.001). Moreover, WBCT in 88.4% of patients identified ≥ 1 incidental finding (mean 3.4) vs. 28.9% by CI only (p < 0.001). Overall, WBCT had treatment consequences in 31.9% of cases (NNP = 3.1). Conclusions The application of WBCT in addition to CI in the emergency treatment of trauma had therapy consequences for almost every third patient. On the other hand, WBCT appeared not to be indicated (ISS < 8) in at least 2/5 of patients.

Abstract
PURPOSE Some surgeons believe that chest computed tomography (CT) scan should be used more prudently in management of blunt chest trauma patients. This study aimed to evaluate the clinical predictors of abnormal chest CT scan findings in trauma patients. METHODS This cross-sectional study was conducted on blunt chest trauma patients aged ≥18 years who were referred to the emergency departments of two educational hospitals and underwent chest CT scan. These patients were enrolled in the study using a non-probability sampling method. The exclusion criteria included: class III or IV hemodynamic shock, need for immediate surgical or neurosurgical interventions, penetrating trauma, lack of required information, and pregnancy. Demographic factors, accident details, trauma mechanism, vital signs, and level of consciousness in predicting abnormal chest CT scan findings were evaluated. Analysis was performed using IBM SPSS statistics 21. RESULTS A total of 977 patients (male 51.5%, female 48.5%) with the mean age of (41.71 ± 14.24) years, range 18-88 years were studied; 34.2% of them with high energy trauma mechanism. With 334 (34.2%) patients had abnormal findings on chest X-ray (CXR) and 332 (34.0%) cases had an abnormal findings on chest CT scan (agreement rate was 99.4%). There was a significant correlation between male gender (p < 0.0001), GCS<15 (p < 0.0001), high energy trauma mechanism (p < 0.0001), unstable hemodynamics (p < 0.01), and clinical signs and symptoms (p < 0.0001) with chest CT findings. Chest wall deformity (odds = 8; p < 0.0001), generalized tenderness (odds = 6.6, p < 0.0001), and decreased cardiac sound (odds = 3.8, p < 0.0001) were the important and independent clinical predictors of abnormal chest CT scan findings. CONCLUSION Based on the findings, chest wall deformity, generalized tenderness, decreased cardiac sound, distracting pain, chest wall tenderness, high energy trauma mechanism, male gender, respiratory rate > 20 breathes/min, decreased pulmonary sound, and chest wall crepitation were independent clinical predictors of abnormal chest CT scan findings following blunt trauma.

Abstract
INTRODUCTION Given the concern for radiation-induced malignancy in children and the fact that risk of severe chest injury in children is low, the risk/benefit ratio must be considered in each child when ordering a computed tomography (CT) scan after blunt chest trauma. METHODS The study included pediatric blunt trauma patients (age, <15 years) with chest radiograph (CR) before chest CT on admission to our adult and pediatric level I trauma center. Surgeons were asked to view the blinded images and reads and indicate if they felt CT was warranted based on CR findings, if their clinical management change based on additional findings on chest CT, and how they might change management. RESULTS Of the 127 patients identified, 64.6% had no discrepancy between their initial CR and chest CT and 35.4% of the children's imaging contained a discrepancy. The majority of the pediatric and general trauma surgeons felt CT was indicated in 6 of 45 patients based on CR. In 87% of patients with a discrepancy in findings on CR and CT, the majority of surgeons agreed that their management would not change based on the additional information. In the 6 patients in which the CT was considered indicated, 4 of the 6 would have triggered a management change. CONCLUSIONS Our study suggests that chest CT scans frequently serve as confirmatory diagnostic tools and in the pediatric blunt chest trauma patient and can be withheld in many cases without hindering the management of an injured child.

Abstract
INTRODUCTION Posttraumatic pneumothorax (PTX) is often overseen in anteroposterior chest X-ray. Chest sonography and Electrical Impedance Tomography (EIT) can both be used at the bedside and may provide complementary information. We evaluated the performance of EIT for diagnosing posttraumatic PTX in a pig model. METHODS This study used images from an existing database of images acquired from 17 mechanically ventilated pigs, which had sustained standardized blunt chest trauma and had undergone repeated thoracic CT and EIT. 100 corresponding EIT/CT datasets were randomly chosen from the database and anonymized. Two independent and blinded observers analyzed the EIT data for presence and location of PTX. Analysis of the corresponding CTs by a radiologist served as reference. RESULTS 87/100 cases had at least one PTX detected by CT. Fourty-two cases showed a PTX > 20% of the sternovertebral diameter (PTXtrans20), whereas 52/100 PTX showed a PTX>3 cm in the craniocaudal diameter (PTXcc3), with 20 cases showing both a PTXtranscc and a PTXcc3. We found a very low agreement between both EIT observers considering the classification overall PTX/noPTX (κ = 0.09, p = 0.183). For PTXtrans20, sensitivity was 59% for observer 1 and 17% for observer 2, with a specificity of 48% and 50%, respectively. For PTXcc3, observer 1 showed a sensitivity of 60% with a specificity of 51% while the sensitivity of observer 2 was 17%, with a specificity of 89%. By programming a semi-automatized detection algorithm, we significantly improved the detection rate of PTXcc3, with a sensitivity of 73% and a specificity of 70%. However, detection of PTXtranscc was not improved. CONCLUSION In our analysis, visual interpretation of EIT without specific image processing or comparison with baseline data did not allow clinically useful diagnosis of posttraumatic PTX. Multimodal imaging approaches, technical improvements and image postprocessing algorithms might improve the performance of EIT for diagnosing PTX in the future.

Abstract
Hemothorax is a collection of blood in the pleural cavity usually from traumatic injury. Chest X-ray has historically been the imaging modality of choice upon arrival to the hospital. The sensitivity and specificity of point-of-care ultrasound, specifically through the Extended Focal Assessment with Sonography in Trauma (eFAST) protocol has been significant enough to warrant inclusion in most Level 1 trauma centers as an adjunct to radiographs.1,2 If the size or severity of a hemothorax warrants intervention, tube thoracostomy has been and still remains the treatment of choice. Most cases of hemothorax will resolve with tube thoracostomy. If residual blood remains within the pleural cavity after tube thoracostomy, it is then considered to be a retained hemothorax, with significant risks for developing late complications such as empyema and fibrothorax. Once late complications occur, morbidity and mortality increase dramatically and the only definitive treatment is surgery. In order to avoid surgery, research has been focused on removing a retained hemothorax before it progresses pathologically. The most promising therapy consists of fibrinolytics which are infused into the pleural space, disrupting the hemothorax, allowing for further drainage. While significant progress has been made, additional trials are needed to further define the dosing and pharmacokinetics of fibrinolytics in this setting. If medical therapy and early procedures fail to resolve the retained hemothorax, surgery is usually indicated. Surgery historically consisted solely of thoracotomy, but has been largely replaced in non-emergent situations by video-assisted thoracoscopy (VATS), a minimally invasive technique that shows considerable improvement in the patients' recovery and pain post-operatively. Should all prior attempts to resolve the hemothorax fail, then open thoracotomy may be indicated.

Abstract
OBJECTIVES The Advanced Trauma Life Support (ATLS) course encourages the use of chest x-ray (CXR) to identify injuries that may change clinical management during the initial stage of trauma resuscitations. Several studies have failed to show benefit for the routine use of CXR without a clinical indication, however. We sought to validate these findings by determining the incidence of clinically significant findings discovered on a portable single-view CXR during the initial stabilization of trauma patients at a Level 1 trauma center. METHODS Using our electronic medical record system, we searched for all of the patients who were brought in as a trauma activation that had a portable single-view CXR performed in the emergency department. We used a selected sampling of available subjects for inclusion into the study. We reviewed the staff radiologist reports for positive findings and reviewed the physician and nursing flow sheets for procedural interventions occurring after the CXR was performed but before leaving the resuscitation area. Subjects who were transferred from another facility, had a thoracic procedure performed before CXR or underwent computed tomography before CXRs were excluded. RESULTS From 2011 through 2012, we found 2101 subjects who had a portable CXR performed in the emergency department. We reviewed the first 400 subjects' records, with 33 (8.3%) subjects having positive findings on CXR. Of those 33, 8 met inclusion criteria and the remainder met exclusion criteria. The most common findings were pneumothorax (n = 4), clavicle fracture (n = 3), and rib fracture (n = 2). No subjects received a procedural intervention before leaving the resuscitation bay to be transported to the operating room or the computed tomography suite. CONCLUSIONS We observed a low incidence of abnormal findings on portable CXR during the initial stabilization of trauma patients, none of whom received an immediate procedural intervention. This dataset supports previously published reports that suggest that a more targeted approach to CXR use may reduce resource utilization.

Abstract
BACKGROUND Patients with stable blunt great vessel injury (GVI) can have poor outcomes if the injury is not identified early. With current pediatric trauma radiation reduction efforts, these injuries may be missed. As a known association between scapular fracture and GVI exists in adult blunt trauma patients, we examined whether that same association existed in pediatric blunt trauma patients. METHODS Bluntly injured patients younger than 18 years old were identified from 2012 to 2014 in the National Trauma Data Bank. Great vessel injury included all major thoracic vessels and carotid/jugular. Demographics of patients with and without scapular fracture were compared with descriptive statistics. The χ test was used to examine this association using SAS Version 9.4 (SAS Institute, Inc, Cary, NC). RESULTS We found a significant association between pediatric scapular fracture and GVI. Of 291,632 children identified, 1,960 had scapular fractures. Children with scapular fracture were 10 times more likely to have GVI (1.2%) compared to those without (0.12%, p < 0.0001). Most common GVI seen were carotid artery, thoracic aorta, and brachiocephalic or subclavian artery or vein. Children with both scapular fracture and GVI were most commonly injured by motor vehicles (57% collision, 26% struck). CONCLUSIONS Injured children with blunt scapular fracture have a 10-fold greater risk of having a GVI when compared to children without scapular fracture. Presence of blunt traumatic scapular fracture should have appropriate index of suspicion for a significant GVI in pediatric trauma patients.

Abstract
PURPOSE The management of chest stab wounds necessitates to perform an efficient imaging strategy. Compared to chest X-ray, computed tomography (CT) scan has a higher sensitivity. Nevertheless, the utility of diagnosing occult injuries remains controversial. Previous studies reported very different rates of management modifications induced by CT-scan. Indeed, no study specifically addressed the issue of ruling out traumatic diaphragmatic injury (TDI) in the specific population of chest stab trauma. The aim of the study was to evaluate the rate of thoracic procedures induced or guided by the results of thoracic CT-scan in the specific population of chest stab wounds. Secondary objective was to evaluate the utility of CT-scan for the diagnosis of TDI. METHODS We conducted a prospective observational study. All consecutive patients referred to the acute care unit were included. We recorded the general characteristics of patients, the localization of wounds, all imaging tests, the final injury diagnosis, and the patients' management. We compared patients with modifications of management induced by CT-scan results to other patients. We evaluated the performance of CT-scan for the diagnosis of TDI by calculating its sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV). RESULTS 153 patients were included. There were 92 patients with normal chest X-ray. 67 of them received a CT-scan. 34 (51%) patients had an abnormal CT-scan, including 19 (21%) patients with thoracic new findings, with 3 (4.5%) modification of management. There were 50 patients who had an abnormal chest X-ray. 31 of them received a CT-scan, and 31 (100%) had an abnormal CT-scan, including 19 thoracic new findings, with 11 (36%) modifications of management. The diagnostic performance of CT-scan for TDI was: sensitivity 50%; specificity 95%; NPV 72%; PPV 88%. CONCLUSIONS In chest stab trauma, CT-scans may be unnecessary outside the thoracoabdominal zone when chest X-ray is normal. In other cases, CT-scan seems to have an impact on the decision-making. In case of thoracoabdominal wounds, CT-scan helps to detect intra-abdominal injuries. The performance of CT-scan to diagnose TDI is not high enough to reliably rule out all TDI.

Abstract
Thoracic injuries caused by blunt trauma are commonly encountered emergencies in veterinary medicine. However, published studies are lacking that compare radiology to CT in blunt trauma caused by motor vehicle accidents in canine patients. The aim of this prospective diagnostic accuracy, methods comparison study were to estimate the sensitivity (Se) and specificity (Sp) of thoracic radiology relative to CT for detecting lung contusions, pneumothorax, pleural effusion, and rib fractures. The study further aimed to develop a severity scoring system for radiology and CT and to compare the findings between the two modalities. The hypothesis was that radiology would be less sensitive than CT at detecting these injuries and that radiology would underestimate the severity of lung contusions. Fifty-nine patients met the inclusion criteria. Radiology underestimated the presence of lung contusions (Se = 69%, 95% confidence interval) and overestimated the severity of the contusions relative to CT. There was high interobserver variability in evaluating lung contusion severity (coefficient of variation = 91%). Both the three-view thoracic and horizontal beam radiography had poor sensitivities for the detecting pneumothorax (Se = 19% and 63%, respectively) and pleural effusions (Se = 43% and 71%, respectively). Similarly, the sensitivity (56%) of radiographs for the detection of rib fractures was poor relative to CT. Findings from the current study indicated that thoracic radiography had low sensitivity for detecting lesions related to blunt thoracic trauma caused by motor vehicle accidents and supported the use of CT as an additional diagnostic imaging modality in these patients.

Abstract
Nail guns are cheap and easy-to-access devices that are common in the industry and personal use and are widely used by untrained people. Life-threatening injuries may occur after a self-accident due to the use of these devices. We report the case of a 47-year-old man who had hemoptysis due to a lung parenchymal injury after nail gun use. Computed tomography revealed focal alveolar hemorrhage. Hemodynamically stable, the patient underwent surgery. Nail guns penetrating the chest can cause life-threatening situations. In the emergency department, rapid diagnosis and treatment is vital in preventing fatal outcome.

Abstract
BACKGROUND With the introduction of the lung allocation score (LAS), sicker patients are prioritized for lung transplantation (LT). There is a lack of data regarding variables independently associated with 30-day mortality after LT. METHODS We queried the UNOS database for adult patients undergoing LT between 1989 and 2014. Patients with dual organ or previous transplantation and those with missing survival data were excluded. Mortality during the first 30 days after LT was the primary outcome variable. RESULTS The yearly trends indicate a statistically significant reduction in the 30-day mortality during the study period (P < 0.001, overall mortality: 5.5%) which has continued in the post-LAS era (P = 0. 014, overall mortality: 3.6%). Among patients with 30-day mortality, "primary non-function" (n = 118, 72.8%) was reported as the most common etiology. Transplant indication of vascular diseases, history of non-transplant cardiac or lung surgery, mean pulmonary pressures >35 mm Hg, disabled functional status, ECMO support, high LAS, ischemic time >6 hours, and blunt injury as the mechanism of donor death are independently associated with 30-day mortality. CONCLUSION The incidence of early mortality after LT continues to decline in the post-LAS era. Apart from the mechanism of donor death and ischemic time, early mortality appears to be primarily driven by the recipient characteristics.

Abstract
AIM To investigate the hemothorax size for which tube thoracostomy is necessary.
METHODS Over a 5-year period, we included all patients who were admitted with blunt chest trauma to our level 1 trauma center. Focus was placed on identifying the hemothorax size requiring tube thoracostomy.
RESULTS A total number of 274 hemothoraces were studied. All patients with hemothoraces measuring above 3 cm received a chest tube. The 50% predicted probability of tube thoracostomy was 2 cm. Pneumothorax was associated with odds of receiving tube thoracostomy for hemothoraces below 2 cm (Odds Ratio: 4.967, 95%CI: 2.225-11.097, P < 0.0001).
CONCLUSION All patients with a hemothorax size greater than 3% underwent tube thoracostomy. Prospective studies are warranted to elucidate the clinical outcome of patients with smaller hemothoraces.

Chest computed tomography imaging improves potential lung donor assessment. J Thorac Cardiovasc Surg 2018; 157:1711-1718.e1.

Abstract
OBJECTIVE Chest computed tomography (CT) imaging is being increasingly used for potential lung donor assessment. However, the efficacy of CT imaging in this setting remains unknown. We hypothesize that chest CT imaging independently affects the decision-making process in donor lung utilization. METHODS We conducted a retrospective cohort study of all adult donation after brain death donors managed through our local organ procurement organization from June 2011 to November 2016. An experienced thoracic radiologist independently reviewed donor chest CT and chest x-ray images in a blinded, standardized manner to determine the presence of structural lung disease (eg, emphysema, interstitial lung disease [ILD]) and acute abnormalities (eg, traumatic lung injury [TLI]). Distinct models of lung utilization were fit to groups with initial partial pressure of oxygen (iPaO2) ≤300 mm Hg (suboptimal) and iPaO2 >300 mm Hg (optimal). RESULTS The organ procurement organization managed 753 donors during the study period, with a lung utilization rate ([lung donors/all organ donors] × 100) of 36.5% (275 of 753). Four hundred forty-five (59.1%) donors received chest CT imaging, revealing emphysema (13.7%), ILD (2.5%), and TLI (7.2%). In univariate analysis, findings of TLI (odds ratio [OR], 2.23; 95% confidence interval [CI], 1.08-4.61) were positively associated with lung utilization, whereas findings of emphysema (OR, 0.18; CI, 0.08-0.40) were negatively associated with utilization. In multivariate analysis, CT findings of emphysema (OR, 0.21; CI 0.08-0.54) remained negatively associated with utilization. No potential donors with CT findings of ILD became lung donors. After controlling for chest x-ray findings, chest CT imaging findings of structural lung disease remained negatively associated with utilization (P = .0001). Lung utilization rate in the suboptimal and optimal iPaO2 populations was 35.1% and 41.4%, respectively, and CT findings of emphysema had a significant association with nonutilization in both groups. CONCLUSIONS In the evaluation of potential lung donors, chest CT imaging findings of structural lung disease, such as emphysema and ILD, have a significant negative association with lung utilization. Our findings suggest that chest CT imaging might be an important adjunct to conventional lung donor assessment criteria.

Chinese expert consensus on echelons treatment of thoracic injury in modern warfare. Mil Med Res 2018; 5:34.

Abstract
The emergency treatment of thoracic injuries varies of general conditions and modern warfare. However, there are no unified battlefield treatment guidelines for thoracic injuries in the Chinese People's Liberation Army (PLA). An expert consensus has been reached based on the epidemiology of thoracic injuries and the concept of battlefield treatment combined with the existing levels of military medical care in modern warfare. Since there are no differences in the specialized treatment for thoracic injuries between general conditions and modern warfare, first aid, emergency treatment, and early treatment of thoracic injuries are introduced separately in three levels in this consensus. At Level I facilities, tension pneumothorax and open pneumothorax are recommended for initial assessment during the first aid stage. Re-evaluation and further treatment for hemothorax, flail chest, and pericardial tamponade are recommended at Level II facilities. At Level III facilities, simple surgical operations such as emergency thoracotomy and debridement surgery for open pneumothorax are recommended. The grading standard for evidence evaluation and recommendation was used to reach this expert consensus.

Abstract
Rib fractures represent up to 55 per cent of thoracic blunt traumatic injuries and lead to significant mortality and morbidity. The aim of this study is to determine whether not only number but also the location of rib fractures can be used to risk stratify patients. This is a retrospective study of all blunt trauma patients who presented with rib fractures from January 1, 2013 to April 1, 2015 and underwent chest CT. Rib fractures were categorized by location. Primary outcome was mortality, secondary outcomes were total hospital length of stay (LOS), intensive care unit LOS, and disposition. Multivariate regressions were performed to determine whether mortality and morbidity was dependent on the number of rib fractures as related to location. Nine hundred and twenty-nine patients were reviewed, 669 fit inclusion criteria, and 35 patients died. Mean Injury Severity Score (18 ± 10), total number of rib fractures (6 ± 5), and age (54 ± 19) significantly correlated with mortality. LOS correlated with the number of rib fractures (P < 0.001). Flail chest of indeterminate location significantly increased mortality (P = 0.002). Controlling for age, gender, and Injury Severity Score and for every lateral rib fracture, patients were 1.13 times (OR; P = 0.001) more likely to die. Posterior rib fractures only effected patient outcome if the patient has three or more posterior ribs broken and the patient was 45 years of age or older (P = 0.044); these patients were 12 times more likely to die. When evaluating blunt force trauma in patients with rib fractures, it is imperative to look at rib fracture location and not only the number of rib fractures sustained to predict outcomes.

Abstract
This study has retrospectively reviewed the medical records of 140 dogs sustaining road traffic accident (RTA), and has examined the population characteristics, medical history, injury type, physical examination, emergency laboratory tests and radiography findings, the animal trauma triage (ATT) score, the length of hospitalisation, the complications and the outcome. The survival rate was 83.2 per cent. Younger dogs sustained more frequently lung contusions and limb fractures, while larger dogs more frequently suffered limb fractures, and smaller dogs and older ones sustained more frequently pelvic fractures and sacroiliac luxation (P<0.05 for all). Dogs sustaining orthopaedic injuries required longer hospitalisation (P<0.001). The survival rates of non-ambulatory dogs (P<0.001) and those with neurological abnormalities (P<0.001), abnormal body temperature (P=0.001), hyperglycaemia (P=0.026) or hypoproteinaemia (P=0.04) at presentation were lower compared with those in which these were absent. The number of injured body systems was significantly (P<0.001) and positively associated with death. Dogs surviving RTA to presentation to the hospital have a good prognosis for survival to discharge. Older age, and high ATT score, abnormal body temperature, neurological deficits, hyperglycaemia and hypoproteinaemia at presentation, and occurrence of multiorgan trauma are negative prognostic indicators in such dogs.

Abstract
Background and purpose Thoracic trauma remains to be a relevant injury to the polytraumatised patient. However, literature regarding how far changes in clinical guidelines for pre- and in-hospital trauma management and diagnostic procedures affect the outcome of multiple injured patients with severe chest injury during a long-term observation period is sparse. Methods Multiple traumatised patients (age≥16y) documented in the TraumaRegister DGU® (TR-DGU) from January 1st 2005 to December 31st 2014 with severe chest trauma (AIS≥3) were included in this study. Demographic data, the pattern of injury, injury severity, radiographic emergency procedures, indication for intubation, duration of mechanical ventilation, emergency surgery, occurrence of complications and mortality were evaluated per year and over time. Results A total of 16,773 patients were analysed. The use of whole body computer tomography increased (p<0.001), while the incidence of plain x-rays decreased (p<0.001). Furthermore, incidence of AISThorax = 3 graded injuries increased (p<0.001) while AISThorax = 4 decreased (p<0.001). Both, rate of patients being intubated at the time of ICU admission decreased (p<0.001) and the time of mechanical ventilation decreased (p<0.001). Additionally, need for emergency surgery, lung failure, sepsis, and multi organ failure all decreased (p<0.001). However, mortality remained unchanged. Interpretation Severity of severe chest trauma and associated complications decreased while diagnostics and treatment improved over time. However, mortality remained unchanged. Our results are in line with those expected in the context of the incidence of CT diagnostics, which has increased parallel to the clinical outcome Thus, our data demonstrate a positive trend in the treatment of patients with severe chest trauma.

Abstract
PURPOSE CT-scan is increasingly used in blunt trauma, but the real impact on patient outcome is still unclear. This study was conducted to assess the effect of performing routine (versus selective) chest and abdominopelvic CT-scan on patient admission time and outcome in blunt trauma. METHODS Conscious and hemodynamically stable high-energy trauma patients were included (n = 140). Routine chest and abdominopelvic CT-scan was requested in addition to the conventional radiography and ultrasound for the intervention group and selective CT-scan according to clinical presentation was done for the control group. Patient admission times in the emergency room and surgery ward, complications, and performed surgical procedures were assessed. "Unsuspected injuries" defined as additional findings on CT-scan, which were not expected before CT-scan, were evaluated. RESULTS Admission time in the emergency ward and admission time in hospital were significantly shorter in the intervention group. Complications were similar in both groups. Abdominopelvic CT-scan in the intervention group revealed nine (7.8%) unsuspected injuries. All of these nine patients had also a positive clinical examination and injuries in other body regions. Chest CT-scan in the intervention group led to additional diagnoses in 17 patients (24.28%) leading to tube thoracostomy in 13 patients (18.57%). CONCLUSION Routine chest and abdominopelvic CT-scan in conscious blunt trauma patients decreases the hospitalization time, but has no impact on patient outcome and probably might lead to overtreatment of occult injuries. The option of using a selective approach should be further evaluated to decrease radiation exposure and facility overuse.

Abstract
Introduction Chest trauma may be blunt or penetrating and the chest is the third most common trauma region. It is a significant cause of mortality. Multidetector computed tomography (MDCT) has been an increasingly used method to evaluate chest trauma because of its high success in detecting tissue and organ injuries. Herein, we aimed to present MDCT findings in patients with blunt and penetrating chest trauma admitted to our department. Methods A total of 240 patients admitted to the emergency department of our hospital between April 2012 and July 2013 with a diagnosis of chest trauma who underwent MDCT evaluations were included. Most of the patients were male (83.3%) and victims of a blunt chest trauma. The images were analyzed with respect to the presence of fractures of bony structures, hemothorax, pneumothorax, mediastinal organ injury, and pulmonary and vascular injuries. Results MDCT images of the 240 patients yielded a prevalence of 41.7% rib fractures, 11.2% scapular fractures, and 7.5% clavicle fractures. The prevalence of thoracic vertebral fracture was 13.8% and that of sternal fracture was 3.8%. The prevalence of hemothorax, pneumothorax, pneumomediastinum, and subcutaneous emphysema was 34.6%, 62.1%, 9.6%, and 35.4%, respectively. The prevalence of rib, clavicle, and thoracic vertebral fractures and pulmonary contusion was higher in the blunt trauma group, whereas the prevalence of hemothorax, subcutaneous emphysema, diaphragmatic injury, and other vascular lacerations was significantly higher in the penetrating trauma group than in the blunt trauma group (p<0.05). Conclusion MDCT images may yield a high prevalence of fracture of bony structures, soft tissue lacerations, and vascular lesions, which should be well understood by radiologists dealing with trauma.

Abstract
Background Thoracic injuries are a leading cause of death in polytrauma patients. Early diagnosis and treatment are of paramount importance. Whole-body computed tomography (WBCT) has largely replaced traditional imaging techniques such as conventional radiographs and focused computed tomography (CT) as diagnostic tools in severely injured patients. It is still unclear whether WBCT has led to higher rates of diagnosis of thoracic injuries and thus to a change in outcomes. Methods In a retrospective study based on the trauma registry of the German Trauma Society (TraumaRegister DGU®), we analysed data from 16,545 patients who underwent treatment in 59 hospitals between 2002 and 2012 (ISS ≥ 9). The 3 years preceding and the 3 years following the introduction of WBCT as a standard imaging modality for the investigation of severely injured patients were assessed for every hospital. Accordingly, patients were assigned to either the pre-WBCT or the WBCT group. We compared the numbers of thoracic injuries and the outcomes of patients before and after the routine use of WBCT. Results A total of 13,564 patients (pre-WBCT: n = 5005, WBCT: n = 8559) were included. Relevant thoracic injuries were detected in 47.8%. There were no major differences between the patient groups in injury severity (pre-WBCT: median ISS 21; WBCT: median ISS 22), injury patterns and demographics. After the introduction of WBCT, only minor changes were observed regarding the rates of most thoracic injuries. Clinically relevant injuries were pulmonary contusions (pre-WBCT: 18.5%; WBCT: 28.7%), injuries to the lung parenchyma (pre-WBCT: 12.6%; WBCT: 5.9%), multiple rib fractures (pre-WBCT: 10.6%; WBCT: 21.6%), and pneumothoraces (pre-WBCT: 17.3%; WBCT: 21.6%). The length of stay in the intensive care unit (pre-WBCT: 10.8 days; WBCT: 9.7 days) and in hospital (pre-WBCT: 26.2 days; WBCT: 23.3 days) decreased. There was no difference in overall mortality (pre-WBCT: 15.5%; WBCT: 15.6%). Conclusions The routine use of WBCT in the trauma room setting has led to changes in patient management that are not reflected in the rates of diagnosis of severe thoracic injuries (e.g. tension pneumothoraces, cardiac injuries, arterial injuries). By contrast, there was a relevant increase in the rates of diagnosis of minor thoracic injuries, which, however, did not result in an improvement in survival prognosis.

Abstract
We aimed to compare the diagnostic performance and inter-observer consistency between low dose chest CT (LDCT) and standard dose chest CT (SDCT) in the patients with blunt chest trauma.A total of 69 patients who met criteria indicative of blunt chest trauma (77% of male; age range, 16-85) were enrolled. All patients underwent LDCT without intravenous (IV) contrast and SDCT with IV contrast using parameters as following: LDCT, 40 mAs with automatic tube current modulation (ATCM) and 100 kVp (BMI <25, n = 51) or 120 kVp (BMI>25, n = 18); SDCT, 180 mAs with ATCM and 120 kVp. Transverse, coronal, sagittal images were reconstructed with 3-mm slice thickness without gap and provided for evaluation of 3 observers. Reference standard images (transverse, coronal, sagittal) were reconstructed using SDCT data with 1-mm slice thickness without gap. Reference standard was established by 2 experienced thoracic radiologists by consensus. Three observers independently evaluated each data set of LDCT and SDCT.Multiple-reader receiver operating characteristic analysis for comparing areas under the ROC curves demonstrated that there was no significant difference of diagnostic performance between LDCT and SDCT for the diagnosis of pulmonary injury, skeletal trauma, mediastinal injury, and chest wall injury (P > 0.05). The intraclass correlation coefficient was measured for inter-observer consistency and revealed that there was good inter-observer consistency in each examination of LDCT and SDCT for evaluation of blunt chest injury (0.8601-1.000). Aortic and upper abdominal injury could not be appropriately compared as LDCT was performed without using contrast materials and this was limitation of this study.The effective radiation dose of LDCT (average DLP = 1.52 mSv⋅mGy cm) was significantly lower than those of SDCT (7.21 mSv mGy cm).There is a great potential benefit to use of LDCT for initial evaluation of blunt chest trauma because LDCT could maintain diagnostic image quality as SDCT and provide significant radiation dose reduction. A further study of LDCT with IV contrast for evaluation of aortic and upper abdominal injury is needed.

Abstract
Pneumothorax is defined as the abnormal presence of air within the pleural space (cavity) that results in the partial or complete collapse of a lung. It can occur spontaneously or due to a traumatic event. Symptoms can vary from a nondescriptive complaint of shortness of breath or chest pain to complete cardiopulmonary collapse. Diagnosis is based on a combination of clinical suspicion along with supporting imaging studies. Treatment often involves surgical or nonsurgical approaches with goal to alleviate symptoms and prevent recurrence.

Abstract
BACKGROUND The precise role of thoracic CT in penetrating chest trauma remains to be defined. We hypothesized that thoracic CT effectively screens hemodynamically normal patients with penetrating thoracic trauma to surgery vs. expectant management (NOM). METHODS A ten-year review of all penetrating torso cases was retrospectively analyzed from our urban University-based trauma center. We included hemodynamically normal patients (systolic blood pressure ≥90) with penetrating chest injuries that underwent screening thoracic CT. Hemodynamically unstable patients and diaphragmatic injuries were excluded. The sensitivity, specificity, positive predictive value and negative predictive value were calculated. RESULTS A total of 212 patients (mean injury severity score=24, Abbreviated Injury Score for Chest=3.9) met inclusion criteria. Of these, 84.3% underwent NOM, 9.1% necessitated abdominal exploration, 6.6% underwent exploration for retained hemothorax/empyema, 6.6% underwent immediate thoracic exploration for significant injuries on chest CT, and 1.0% underwent delayed thoracic exploration for missed injuries. Thoracic CT had a sensitivity of 82%, specificity of 99%, positive predictive value of 90%, a negative predictive value of 99%, and an accuracy of 99% in predicting surgery vs. NOM. CONCLUSIONS Thoracic CT has a negative predictive value of 99% in triaging hemodynamically normal patients with penetrating chest trauma. Screening thoracic CT successfully excludes surgery in patients with non-significant radiologic findings.

Abstract
BACKGROUND The majority of patients with severe blunt chest trauma is successfully treated with supportive measures and thoracostomy tube; only few cases need urgent thoracotomy. Lung-sparing techniques are treatments of choice but major pulmonary resections are necessary in case of injuries involving hilar vessels or bronchi. Currently the mortality associated with pulmonary lobectomy performed for chest trauma is 40%. METHODS Over a 2-year period [2013-2014], 210 patients with chest trauma were hospitalized at our Institution. Mechanism of injury was blunt in 204 (97.1%) patients and penetrating in 6 (2.9%). In 48 (22.8%) patients was necessary a ventilatory support and 37 (17.6%) patients were treated with thoracostomy tube. Nineteen (9%) patients needed urgent thoracotomy: 4 (1.9%) cases for penetrating injury and 15 (7.1%) cases for blunt trauma. Three (1.4%) patients treated with urgent thoracotomy required concomitant laparotomy for intra-abdominal injuries. The overall mortality rate was 1.4%. RESULTS We report three cases of urgent lobectomies for chest trauma without mortality and with postoperative complete restoration of respiratory function. The anatomical lobectomies were performed for: massive hemothorax with bronchial disruption, expanding pulmonary hematoma with hypovolemic shock, and massive hemothorax in deep parenchymal laceration. CONCLUSIONS Mortality rate after major pulmonary resections for trauma is very high and increases with the presence of multivisceral injuries, the severity of hypovolemic shock and extent of lung resection. Anterolateral thoracotomy was the approach employed in case of cardiac arrest. In hypovolemic patients a posterolateral incision with a double lumen intubation was performed. The absence of mortality in this series may be related to the prompt diagnosis, short operative time and absence of associated severe neurological or abdominal injuries.

Abstract
In the immediate assessment of trauma patients, critical pitfalls exist that may interfere with optimal clinical care. Failure to recognize the need for early anaesthesia and endotracheal intubation may put the patient at unnecessary risk and delay the assessment and treatment process. Pressure to clear the cervical spine may lead to inadequate imaging and premature removal of neck immobilization devices. The limitations of the initial chest X-ray in diagnosing pneumothoraces may not be appreciated and needle thoracentesis may be ineffective. ‘Springing’ the pelvis to assess for instability may cause life-threatening haemorrhage and should not be done prior to the initial pelvic X-ray. Log rolling may dislodge crucial clot formation and promote bleeding, and should only be used for diagnostic purposes. Applying clinical common sense to the assessment of trauma patients may avoid the pitfalls whilst allowing the clinician to operate within internationally agreed assessment and treatment frameworks.

Abstract
BACKGROUND Whole body computed tomography in trauma (WBCTT) is a standardized CT examination of trauma patients. It has a relatively high radiation dose. Therefore, well-defined clinical indications and imaging protocols are needed. This information regarding Nordic countries is limited. PURPOSE To identify Nordic countries' WBCTT imaging protocols, radiation dose, and integration in trauma care, and to inquire about the need for common Nordic guidelines. MATERIAL AND METHODS A survey with 23 multiple choice questions or free text responses was sent to 95 hospitals and 10 trauma centers in and outside the Nordic region, respectively. The questions were defined and the hospitals selected in collaboration with board members of "Nordic Forum for Trauma and Emergency Radiology" (www.nordictraumarad.com). RESULTS Two Nordic hospitals declined to take part in the survey. Out of the remaining 93 Nordic hospitals, 56 completed the questionnaire. Arterial visualization is routine in major trauma centers but only in 50% of the Nordic hospitals. The CT scanner is located within 50 m of the emergency department in all non-Nordic trauma centers but only in 60% of Nordic hospitals. Radiation dose for WBCTT is in the range of 900-3600 mGy × cm. Of the 56 responding Nordic hospitals, 84% have official guidelines for WBCTT. Eighty-nine percent of the responders state there is a need for common guidelines. CONCLUSION Scanning protocols, radiation doses, and routines differ significantly between hospitals and trauma centers. Guideline for WBCTT is presently defined locally in most Nordic hospitals. There is an interest in most Nordic hospitals to endorse new and common guidelines for WBCTT.

Abstract
Objectives Using whole-body multislice computed tomography (MSCT) excessively or with irrelevant indications can be seen in many centers. The aim of this study was to analyze retrospectively the MSCT findings in trauma patients admitted to the emergency department. Methods Records of the patients who have applied to the emergency department due to blunt trauma in a 12 month period and whose whole body MSCT images have been taken, were evaluated using the “Nucleus Medical Information System”. Results The most frequent type of trauma was traffic accidents in 61.4%, falling down from the height in 22.4%, and motorcycle accidents in 11.4% of patients. Of the patients, 25.2% were discharged from the emergency, while 73.8% were hospitalized. At least one CT findings associated with trauma was present in 61.4% of our patients. Pathological findings in MSCT were most frequently detected in the head and face (35.3%) and thoracic (28.6%) regions, respectively. The most common finding in the head and face region was fractures. The most common pathological findings in the thoracic region were pulmonary contusion and rib fractures. A significant relationship was detected between trauma type and spinal MSCT result (p < 0.001). In a large percentage of the patients, MSCT findings were normal in the abdominal region and genitourinary system. Vertebral fractures were most frequently detected in the thoracolumbar region. Conclusions In our study, our rate of negative CT was found to be 38.6%, which is a higher ratio compared to other studies conducte on this topic.

Abstract
BACKGROUND The appropriate sequence of different imagings and indications of thoracic computed tomography (TCT) in evaluating chest trauma have not yet been clarified at present. The current study was undertaken to determine the value of chest X-ray (CXR) in detecting chest injuries in patients with blunt trauma. METHODS A total of 447 patients with blunt thoracic trauma who had been admitted to the emergency department (ED) in the period of 2009-2013 were retrospectively reviewed. The patients met inclusion criteria (age>8 years, blunt injury to the chest, hemodynamically stable, and neurologically intact) and underwent both TCT and upright CXR in the ED. Radiological imagings were re-interpreted after they were collected from the hospital database by two skilled radiologists. RESULTS Of the 447 patients, 309 (69.1%) were male. The mean age of the 447 patients was 39.5±19.2 (range 9 and 87 years). 158 (35.3%) patients were injured in motor vehicle accidents (MVA). CXR showed the highest sensitivity in detecting clavicle fractures [95%CI 78.3 (63.6-89)] but the lowest in pneuomediastinum [95%CI 11.8 (1.5-36.4)]. The specificity of CXR was close to 100% in detecting a wide array of entities. CONCLUSION CXR remains to be the first choice in hemodynamically unstable patients with blunt chest trauma. Moreover, stable patients with normal CXR are candidates who should undergo TCT if significant injury has not been ruled out.
