Abstract
BACKGROUND Clinicians, afraid of missing intracranial injuries, liberally obtain computed tomographic (CT) head imaging in blunt trauma patients. Prior work suggests that clinical criteria (National Emergency X-Radiography Utilization Study [NEXUS] Head CT decision instrument [DI]) can reliably identify patients with important injuries, while excluding injury, and the need for imaging in many patients. Validating this DI requires confirmation of the hypothesis that the lower 95% confidence limit for its sensitivity in detecting serious injury exceeds 99.0%. A secondary goal of the study was to complete an independent validation and comparison of the Canadian and NEXUS Head CT rules among the subgroup of patients meeting the inclusion and exclusion criteria. METHODS AND FINDINGS We conducted a prospective observational study of the NEXUS Head CT DI in 4 hospital emergency departments between April 2006 and December 2015. Implementation of the rule requires that patients satisfy 8 criteria to achieve "low-risk" classification. Patients are excluded from "low-risk" classification and assigned "high-risk" status if they fail to meet 1 or more criteria. We examined the instrument's performance in assigning "high-risk" status to patients requiring neurosurgical intervention among a cohort of 11,770 blunt head injury patients. The NEXUS Head CT DI assigned high-risk status to 420 of 420 patients requiring neurosurgical intervention (sensitivity, 100.0% [95% confidence interval [CI]: 99.1%-100.0%]). The instrument assigned low-risk status to 2,823 of 11,350 patients who did not require neurosurgical intervention (specificity, 24.9% [95% CI: 24.1%-25.7%]). None of the 2,823 low-risk patients required neurosurgical intervention (negative predictive value [NPV], 100.0% [95% CI: 99.9%-100.0%]). The DI assigned high-risk status to 759 of 767 patients with significant intracranial injuries (sensitivity, 99.0% [95% CI: 98.0%-99.6%]). The instrument assigned low-risk status to 2,815 of 11,003 patients who did not have significant injuries (specificity, 25.6% [95% CI: 24.8%-26.4%]). Significant injuries were absent in 2,815 of the 2,823 patients assigned low-risk status (NPV, 99.7% [95% CI: 99.4%-99.9%]). Of our patients, 7,759 (65.9%) met the inclusion and exclusion criteria of the Canadian Head CT rule, including 111 patients (1.43%) who required neurosurgical intervention and 306 (3.94%) who had significant intracranial injuries. In our study, the Canadian criteria for neurosurgical intervention identified 108 of 111 patients requiring neurosurgical intervention to yield a sensitivity of 97.3% (95% CI: 92.3%-99.4%) and exhibited a specificity of 58.8% (95% CI: 57.7%-59.9%). The NEXUS rule, when applied to this same cohort, identified all 111 patients requiring neurosurgical intervention, yielding a sensitivity of 100% (95% CI: 96.7%-100.0%) with a specificity of 32.6% (95% CI: 31.5%-33.6%). Our study found that the Canadian medium-risk factors identified 301 of 306 patients with significant injuries (sensitivity = 98.4%; 95% CI: 96.2%-99.5%), while the NEXUS rule identified 299 of these patients (sensitivity = 97.7%; 95% CI: 95.3%-99.1%). In our study, the Canadian medium-risk rule exhibited a specificity of 12.3% (95% CI: 11.6%-13.1%), while the NEXUS rule exhibited a specificity of 33.3% (95% CI: 32.3%-34.4%). Limitations of the study may arise from application of the rule by different clinicians in different environments. Clinicians may vary in their interpretation and application of the instrument's criteria and risk assignment and may also vary in deciding which patients require intervention. The instrument's specificity is also subject to spectrum bias and may change with variations in the proportion of "low-risk" patients seen in other centers. CONCLUSIONS The NEXUS Head CT DI reliably identifies blunt trauma patients who require head CT imaging and could significantly reduce the use of CT imaging.

Abstract
Blunt thoracic aortic injury (BTAI) in a patient with an aberrant right subclavian artery (ARSA) presents unique challenges for patient management and aortic repair. Specific considerations include the need to treat coincidental ARSA, subclavian revascularization, and ARSA exclusion. Despite the rise of endovascular repair as the primary modality for aortic repair for BTAI, reports of this technique in the setting of ARSA are limited. Here we describe 3 patients with ARSA who underwent TEVAR for BTAI, and discuss critical management and technical issues in these patients.

Abstract
Abdominal angiography with selective arteriography and subsequent embolisation is an accepted management modality in the treatment of selected solid organ injuries following blunt abdominal trauma. This management practice is well established in the haemodynamically stable patient; however, this remains more controversial in haemodynamically compromised patients, though warrants consideration in both cases due to the associated benefits of non-operative management. This case report describes the successful non-operative management of a severe renal injury in a young polytraumatised patient following a high-speed motor vehicle crash. In addition, the rare CT diagnosis and management of an acute traumatic arteriocalcyeal fistula is discussed with a focus on the importance of renal parenchymal preservation.

Abstract
Pulmonary contusion is a common finding after blunt chest trauma. It occurs in 23-35% of all cases. Alveolar capillaries are injured due to the trauma, which results in accumulation of blood and other fluids within lung tissue. The fluids interfere with gas exchange, leading to hypoxemia. The consequences of pulmonary contusion include ventilation/perfusion mismatching, increased AV shunts and loss of compliance of lung parenchyma. These physiological consequences are manifested within hours from injury and usually resolve in 7 days. Computed tomography (CT) is a sensitive and main diagnostic tool. Clinical symptoms include hypoxemia and hypercapnia, manifested predominantly during 72 hours from injury. Patients are treated primarily conservatively; surgery may be needed due to haemothorax associated with lung contusion or progression of AV shunts due to localized pulmonary contusion.Key words: pulmonary contusion blunt chest trauma computed tomography.

Abstract
UNLABELLED Blunt colorectal traumas are rare clinical entities with a challenging diagnostic and operative management. We describe the case of a 40-year-old man, victim of an accidental fall from a height of four meters who was subsequently diagnosed to have a blunt rectal trauma. A first CT scan showed fracture of the skull and an extensive subcutaneous haematoma of the lower back associated with a fracture of the left transverse processes of lumbar vertebrae. No other visceral abdominal lesions were recognized and patient was admitted to our department for observational studies. After 48 hours from admission the patient presented a subcutaneous emphysema suspicious for hollow viscus injuries. A digital rectal examination detected a laceration both of the posterior rectal wall and the superior anal margin. The patient was successfully managed with spur colostomy, transanal evacuation of the retroperitoneal haematoma and primary repair of both the sphincteric muscle and the rectal wall. As soon as the patient achieved full recovery we performed a reversal colostomy. Diagnosis and management of rectal blunt trauma is still a matter of debate and no definitive recommendation treatments are available. The surgical treatment should be tailored on patient medical conditions and clinicians should maintain a high index of suspicious because a delay in diagnosis can result in higher morbidity and mortality rate.

Abstract
UNLABELLED The aim of this case report is to be aware of occult carotid lesions in thoracic- abdominal trauma because, carotid artery injury consequent to blunt trauma is rare, affecting less than 1% of patients as reported in literature. A 45-years-old female, involved in a traffic accident, arrived to Emergency Room hemodynamically stable, with a Glasgow Coma Scale of 15, complaining abdominal pain, without any neurological signs. She underwent Computed Tomography (CT) scan that showed a complete disruption of left abdominal wall muscles, associated with massive bowel loops herniation. No free air nor other visceral injuries were found. The radiological brain evaluation was negative for neurological injuries. Considering the nature of the trauma, an explorative laparotomy was performed. During the fifth postoperative day, the patient presented neurological side signs with right facial-brachial-crural hemiparesis and expressive aphasia. Head and neck CT scan revealed a lesion of the left common carotid artery with distal embolization of the internal carotid. A left-carotid-axis revascularization procedure and a surgical endarterectomy were immediately performed. Patient was discharged after 20 days without neurological consequences. Physicians should be aware of neck vascular injuries when evaluating patients with multiple trauma, even in neurological asymptomatic patients without seatbelt abrasions of the neck skin.

Abstract
The geriatric population is growing and trauma providers are often tasked with caring for injuries in the elderly. There is limited information regarding injury patterns in geriatric trauma patients stratified by mechanism of injury. This study intends to investigate the comorbidities, mechanisms, injury patterns, and outcomes in geriatric blunt trauma patients. A retrospective study of the 2012 National Trauma Databank was performed. Adult blunt trauma patients were identified; geriatric (>/=65) patients were compared with younger (<65) patients regarding admission demographics and vital signs, mechanism and severity of injury, and comorbidities. The primary outcome was injuries sustained and secondary outcomes included mortality, length of stay in the intensive care unit and hospital, and ventilator days. There were 589,830 blunt trauma patients who met the inclusion criteria, including 183,209 (31%) geriatric and 406,621 (69%) nongeriatric patients. Falls were more common in geriatric patients (79 vs 29%, P < 0.0001). Geriatric patients less often had an Injury Severity Score >/=16 (18 vs 20%, P < 0.0001) but more often a head Abbreviated Injury Scale >/=3 (24 vs 18%, P < 0.0001) and lower extremity Abbreviated Injury Scale >/=3 (24% vs 8%, P < 0.0001). After logistic regression older age was an independent risk factor for mortality for the overall population and across all mechanisms. Falls are the most common mechanism for geriatric trauma patients. Geriatric patients overall present with a lower Injury Severity Score, but more often sustain severe injuries to the head and lower extremities. Injury patterns vary significantly between older and younger patients when stratified by mechanism. Mortality is significantly higher for geriatric trauma patients and older age is independently associated with mortality across all mechanisms.

Abstract
Aortic regurgitation resulting from blunt chest trauma has been reported only 95 times, to our knowledge. The noncoronary and right coronary cusps are the cardiac structures most often injured. Although the aortic leaflets can appear to be undamaged after nonpenetrating trauma, they can have pathologic abnormalities and insufficient function. Some cases of posttraumatic aortic regurgitation progress slowly. Aortic valve replacement is the optimal treatment. We present the case of a then-62-year-old man who has lived more than 5 years after blunt-trauma aortic regurgitation. His is the only case of long-term survival on medical therapy alone among the 96 cases summarized in this report.

Abstract
OBJECTIVE To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. MATERIALS AND METHODS A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. RESULTS Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18-24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. CONCLUSION Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair.

Abstract
Intra-thoracic herniation of abdominal organs following diaphragmatic rupture represents an unusual clinical occurrence with great diagnostic difficulty. The authors present a case of right diaphragmatic rupture related to peritonitis due to perforated duodenal ulcer in previous (1 year before) thoraco-abdominal trauma with complete intra-thoracic herniation of the liver, gallbladder, ascending and transverse colon and lung collapse. The preoperative diagnosis has been based on clinical, chest X-ray, and ultrasound examination. The patient, because of very serious respiratory and hemodynamic distress, immediately underwent surgery (thoraco-laparotomic approach) with reduction of the liver, gallbladder, ascending and transverse colon in the abdominal cavity, perforated duodenal ulcer suture and repair of diaphragmatic tear using an unusual repair mode: suture of autologous fascia lata graft to the diaphragm. Postoperative chest radiography showed the normal location of right diaphragmatic border.

Abstract
Injury to the solid abdominal organs-liver, spleen, kidney, and pancreas-is one of the most common injury patterns in pediatric blunt trauma. Pediatric trauma centers are becoming increasingly successful in managing these injuries without operative intervention. Well-validated guidelines have been established for liver and spleen injury management, and operative intervention is reserved for patients who show evidence of active bleeding after resuscitation. No such guidelines yet exist for the management of traumatic injury of the kidney or pancreas. Exploratory laparotomy remains the treatment of choice in patients suffering hemodynamic collapse, but interventional radiologic or endoscopic procedures are increasingly used to manage all but the most devastating solid organ injuries.

Abstract
Purpose: To report successful endovascular stent-graft placement for emergency treatment of a complex traumatic injury involving the aortic arch and multiple arch vessels. Case Report: An 81-year-old man underwent stent-graft placement for a complex traumatic vascular injury. Computed tomography on admission documented a dissection along the course of the aortic arch, intramural hematoma along the ascending aorta, dissection of the innominate artery, and a right subclavian artery pseudoaneurysm. The dissection of the aortic arch and the pseudoaneurysm of the right subclavian artery were treated immediately, the dissection of the innominate artery 7 days later. The patient did not develop any complications. Follow-up studies performed prior to discharge and at 6 and 12 months after the interventions showed successful repair of the complex vascular injuries. Conclusions: Traumatic injury of the aortic arch with multiple arch vessel involvement can be treated effectively by means of stent-graft placement.

Abstract
INTRODUCTION Avulsion of the optic nerve head is a rare and severe complication of ocular blunt trauma. The case reported is a 28-year old man presenting to the emergency department due to blunt trauma to his right eye globe with a tree branch. Lid haematoma and subconjunctival haemorrhage were present. Visual acuity soon after the injury was counting fingers (CF) and on admission to the Department of Ophthalmology he had no light perception (NLP). Fundus examination revealed prepapillary haemorrhage, which after few days dispersed into the vitreous cavity. Despite no light perception in the affected eye, the patient was qualified for vitrectomy. During surgery, an optic nerve avulsion with cicatricial gliosis was diagnosed. Six months after vitrectomy, the visual acuity was NLP in the right eye. DISCUSSION The clinical signs, mechanism, treatment and natural history of this poorly known disease are described. CONCLUSION Optic nerve avulsion must be considered in cases of trauma with forced rotation of the eye. Damage occurring at the disc may suggest mechanisms involving anterior luxation of the globe, retropulsion of the nerve, forced globe rotation, or a sudden explosive rise in intraocular pressure blowing the nerve off the sclera into its dural sheath. Damage and break of the nerve fibres are responsible for immediate visual impairments, and involving secondary haematomas and oedemas In spite of required safety precautions in agriculture work, eye injuries are still prevalent. Blunt ocular trauma remains a large part of this group, leading even to irreversible blindness.

Abstract
Less than one percent of trauma admission cases are categorized as pediatric neck trauma [13]. Nevertheless, due to an increasingly mobile society, there has been an increasing frequency of pediatric neck trauma with motor vehicle accidents being the most common mechanism of injury [8]. We present a case of laryngotracheal separation from a blunt, clothesline injury to the neck in a pediatric patient. We also review the literature and discuss the benefit of balloon airway dilation and its assistance in the management of laryngeal trauma and its resultant effects.

Abstract
BACKGROUND The aim of this study was to confirm our clinical impression that intra-abdominal handlebar injuries are progressively increasing in number and severity in the latest years. METHODS A retrospective analysis of data concerning 132 patients admitted to our department of pediatric surgery during a 10-year period (between 2003 and 2012), following bicycle-related blunt abdominal trauma, was performed. Patients were divided into two groups: those who fall from their bicycle (N.=43) and those who sustained direct impact from the handlebars (N.=89) and compared. RESULTS Number of admitted patients due to bike related injury was increased during a 10-year period. The bikes used by 91.6% of the participants were the high quality BMX, with rigid and strong handlebars. The average age for both groups was 10.3 years (4-16 years). Boys were injured more than girls. Thirty patients from both groups sustained severe abdominal visceral injuries, 25 from the handlebar group and 6 from the fall group (P=0.018). The overall average length of hospital stay was 3.04 days, with 36 cases (27.36%) requiring pediatric intensive care unit (PICU) admission (N.=26 of the handlebar group and N.=10 of the fall group, P=0.024). Eight children sustaining handlebar injuries required abdominal surgery compared to only one case for the fall group (P=0.018), when excluding extra-abdominal procedures. CONCLUSIONS Number of pediatric patients admitted due to bike related injury has been gradually increasing. Children who suffer from direct impact of the handlebars are more likely to require abdominal operative intervention and PICU admission than those who fall. Preventive measures are urgently needed in order to defeat this trend.

Abstract
Blunt thoracic aortic injury (BTAI) resulting from cardiopulmonary resuscitation (CPR) is rarely reported and most reports are of aortic rupture. Clinical reports have also documented aortic dissection and intramural hematomas with sequential imaging showing the development of these aortic injuries after the administration of CPR, suggesting that non-transmural aortic injury may also result from CPR. We report partial separation of an aortic intimal atheromatous plaque as a component injury in a case with multiple complications of manual CPR. A 74-year-old male presented to the emergency room (ER) with a 2-day history of chest pain. While in the ER, he suffered witnessed cardiac arrest and resuscitative attempts were pursued for 60 min prior to declaring death. At autopsy, there were numerous injuries attributable to CPR, including bilateral rib fractures, sternal fracture, retrosternal and mediastinal hemorrhage, epicardial ecchymoses, and ruptured pericardium. There was a perforated inferior wall myocardial infarct with a large left hemothorax. There was partial separation/laceration of an intimal atheromatous plaque on the anterior wall of the ascending aorta proximal to the origin of the brachiocephalic artery, forming a triangular flap, without associated intramedial dissection or hematoma. There was no thrombus formation, effectively excluding existence of the laceration prior to circulatory arrest. This aortic injury provides pathologic confirmation of non-transmural BTAI definitively sustained during manual CPR. Pathologists and clinicians alike should be cognizant of the possibility of BTAI resulting from CPR, which may manifest the full range of severity from intimal tear through aortic rupture.

Abstract
We present a rare case of a 74 year old man admitted by ambulance to our department following a blunt minor abdominal trauma (veal attack). He complained of pain in the left abdominal flank and in the lower abdomen. The lower abdomen was tender, moderate distended but not rigid. He also had a left inguinal uncomplicated hernia. Because he was hemodynamic stable we performed a CT - scan who revealed several pockets of free air anteriorly in the midline. One hour and a half after admission the pacient underwent exploratory laparotomy, revealing a antimesostenic perforation of the ileum about 120 cm from the ileo-cecal valve. Simple closure in one layer was performed. The inguinal hernia wasn't repaired at the time of the first surgery. The postoperative course was favorable, the pacient being discharged on the 8th postoperative day.

Abstract
A 22-year-old woman presented to the emergency department (ED) after suffering injuries as a restrained driver in a head-on motor vehicle accident. Upon presentation to the ED, her Glasgow Coma Score (GCS) was 15. A computed tomography (CT) of the head and neck was negative. She was taken to surgery for orthopedic injuries. Recovery from general anesthesia was somewhat prolonged due to somnolence. Roughly two hours after transfer, her family noticed that she was not moving her left arm. Trauma staff noted she had a new left hemiparesis. She was promptly taken for a repeat head CT which showed a dense area of ischemia in her right cerebral hemisphere, in the distribution of the right middle cerebral artery (MCA). A CT angiogram of the head and neck revealed a large dissection of the right carotid artery below the level of C2-C3, complete occlusion of the right internal carotid artery beginning 2 cm superior to the bifurcation, and developing cerebral edema with subsequent leftward shift.

Abstract
Blunt abdominal aortic injury (BAAI) is very rare. In general, BAAI occurs in high-energy accidents. Here, we present a case of BAAI in a low-energy accident. A 70-year-old female was injured after falling 3 m. Her vital signs were stable. She had lumbar fractures (L1, L2) and BAAI associated with a fragment of the fractured L2 vertebral body. On the fifth posttrauma day, we performed an operation because computed tomography showed a bone fragment of the lumbar fractures (L1, L2) threatening the abdominal aorta. The aortic injury site was transected, and the fragment of the L2 vertebral body was removed. Even in low-energy accidents, BAAI should be considered. BAAI with stable vital signs can be electively treated.

Abstract
The chest response of the human body has been studied for several load conditions, but is not well known in the case of steering wheel rim-to-chest impact in heavy goods vehicle frontal collisions. The aim of this study was to determine the response of the human chest in a set of simulated steering wheel impacts. PMHS tests were carried out and analysed. The steering wheel load pattern was represented by a rigid pendulum with a straight bar-shaped front. A crash test dummy chest calibration pendulum was utilised for comparison. In this study, a set of rigid bar impacts were directed at various heights of the chest, spanning approximately 120mm around the fourth intercostal space. The impact energy was set below a level estimated to cause rib fracture. The analysed results consist of responses, evaluated with respect to differences in the impacting shape and impact heights on compression and viscous criteria chest injury responses. The results showed that the bar impacts consistently produced lesser scaled chest compressions than the hub; the Middle bar responses were around 90% of the hub responses. A superior bar impact provided lesser chest compression; the average response was 86% of the Middle bar response. For inferior bar impacts, the chest compression response was 116% of the chest compression in the middle. The damping properties of the chest caused the compression to decrease in the high speed bar impacts to 88% of that in low speed impacts. From the analysis it could be concluded that the bar impact shape provides lower chest criteria responses compared to the hub. Further, the bar responses are dependent on the impact location of the chest. Inertial and viscous effects of the upper body affect the responses. The results can be used to assess the responses of human substitutes such as anthropomorphic test devices and finite element human body models, which will benefit the development process of heavy goods vehicle safety systems.

Abstract
Blunt chest trauma is a very rare cause of valve disorder. Moreover, mitral valve involvement is less frequent than is aortic or tricuspid valve involvement, and the clinical course is usually acute. In the present report, we describe the case of a 49-year-old man with a perivalvular mitral injury that became clinically manifest one year after a violent, nonpenetrating chest injury. This case is atypical in regard to the valve involved (isolated mitral damage), the injury type (perivalvular leak in the absence of subvalvular abnormalities), and the clinical course (interval of one year between trauma and symptoms).

Abstract
AIM Chronic traumatic thoracic aneurysms are results of blunt trauma of the chest during motorcar accident. Treatment of choice is the endovascular procedure with stent-graft. METHODS Between 2000-2012 in General and Thoracic Surgery Department 30 patients with post-traumatic aneurysms were operated. In all cases aneurysm was located below left subclavian artery and in 63% developed during road traffic accident. RESULTS All patients were operated on with 100% technical success and no device failure was noticed. None of patients died during the endovascular procedure and no serious complications like spinal cord ischemia was observed. In one (3%) case, where left subclavian artery was covered, stroke was diagnosed treated conservatively. CONCLUSION At long-term follow-up, one endoleak type IA was found, solved with balloon-plasty. Two patients died due to cardiac diseases.

Abstract
INTRODUCTION Despite the high frequency of thoracic injuries secondary to traffic related accidents, the blunt cardiac valve rupture is extremely rare. METHOD Case report and review of the literature using PubMed/MEDLINE and EMBASE databases. RESULT A 38 year old female patient, victim of car accident was admitted. On primary survey the patient was conscious, cooperative and hemodynamic and respiratory stable. On secondary survey was found a bilateral open leg fracture and a seat belt sign. Whole body Computed Tomography revealed minimal haemorrhagic contusion of the cortex, left hemopneumothorax and right pneumothorax, bilateral rib fractures, liver contusion, left femoral neck fracture and fracture to the lumbar spinal column. After bilateral pleurostomy, the patient becomes hemodynamically unstable, but with no signs of external bleeding. The transthoracic echocardiography revealed an acute severe tricuspid regurgitation with hepatic veins reflux. After orthopaedic surgeries, the tricuspid valve rupture was managed by replacing the valve with a bioprostheses. The hospital stay was 122 days. CONCLUSION Only a high index of suspicion may reveal blunt cardiac lesions as a cause for hemodynamic instability in acute setting.
