Factors Associated with Cardiac/Pericardial Injury among Blunt Injury Patients: A Nationwide Study in Japan.

The lack of established diagnostic criteria makes diagnosing blunt cardiac injury difficult. We investigated the factors associated with blunt cardiac injury using the Japan Trauma Data Bank (JTDB) in a multicenter observational study of blunt trauma patients conducted between 2004 and 2018. The primary outcome was the incidence of blunt cardiac/pericardial injury. Multivariable logistic regression analysis was used to identify factors independently associated with blunt cardiac injuries. Of the 228,513 patients, 1002 (0.4%) had blunt cardiac injury. Hypotension on hospital arrival (adjusted odds ratio (AOR) 4.536, 95% confidence interval (CI) 3.802–5.412), thoracic aortic injury (AOR 2.722, 95% CI 1.947–3.806), pulmonary contusion (AOR 2.532, 95% CI 2.204–2.909), rib fracture (AOR 1.362, 95% CI 1.147–1.618), sternal fracture (AOR 3.319, 95% CI 2.696–4.085). and hemothorax/pneumothorax (AOR 1.689, 95% CI 1.423–2.006)) was positively associated with blunt cardiac injury. Regarding the types of patients, car drivers had a higher rate of blunt cardiac injury compared to other types of patients. Driving a car, hypotension on hospital arrival, thoracic aortic injury, pulmonary contusion, rib fracture, sternal fracture, and hemothorax/pneumothorax were positively associated with blunt cardiac injury.

Isolated sternal fracture after low-energy trauma in a geriatric patient: a case report

BackgroundFalls are a common cause of emergency department (ED) visits for the older population. If osteoporosis is present, even falls from standing height can lead to unusual fractures normally associated with high-energy trauma. In this report, we analyze a rare case of an isolated sternal fracture with an unusual mechanism of injury. Our discussion aims to improve care for older adults with fall-related fractures.Case presentationAn 86-year-old female presented in the ED of our hospital with a complaint of chest pain. She recalled a fall at home the previous day and described how her fist was impacted between the floor and her chest. A physical examination revealed local tenderness in the mid-chest. A lateral chest x-ray indicated a sternal fracture, and a chest computed tomography scan ruled out concomitant injuries. There were no acute changes on her electrocardiogram (ECG). Conservative outpatient treatment was started, and referrals were made with a recommendation to initiate fall prevention measures and osteoporosis screening in primary health care.ConclusionsGeriatric patients can present in the ED with a rare sternal fracture even after only a minor chest trauma. Appropriate imaging and an ECG are warranted to exclude life-threatening additional injuries. An in-depth physical examination and an understanding of the exact mechanism of injury are important to avoid missing fractures in unexpected locations. Modern ED physicians could have an important role in the secondary prevention of fall-related fractures for geriatric patients.

Nuss Procedure for pectus excavatum repair in a patient with osteogenesis imperfecta

A 17-year-old male with Osteogenesis Imperfecta (OI) type 1 and history of prior spinal instrumentation for kyphosis presented with severe symptomatic pectus excavatum (PEx). His Haller index was 6.7 with a Pectus Correction Index of 51%. He underwent uncomplicated Nuss procedure with insertion of 3 bars and complete repair of the PEx. A single sternal fracture was sustained during correction and healed without deformity. After two years, he developed left-sided pain and two of 3 bars were removed with maintained chest correction. This case report demonstrates the feasibility of Nuss procedure in adolescents with OI and outlines improvements to the technique in future patients with OI. • The Nuss procedure is feasible in teenagers with osteogenesis imperfecta. • Bone mass density should be optimized with bisphosphonates prior to procedure. • Multiple bars and vertical sternal elevation clamp placement may decrease fractures.

A combined laparoscopic and open delayed repair of a rare traumatic abdominal wall hernia

Introduction: Traumatic abdominal wall hernias (TAWHs) are uncommon and result from a high-energetic blunt trauma to the abdomen. These hernias are not always apparent in initial trauma evaluation. No consensus exists regarding optimal timing and surgical approach. Case Presentation: A 68-year-old Caucasian woman was involved as a passenger in a high-energetic head-on collision motor vehicle accident. In the initial assessment a sternal fracture, four rib fractures, a small pneumothorax, and a medial malleolus fracture were found. A small abdominal wall hernia was missed. Six months later she presents with a painful mass in her left flank. Computed tomography (CT) showed a large hernia containing colon. An elective hybrid repair was done. Laparoscopically, a preperitoneal mesh was placed. Afterward, using open access, the abdominal wall musculature was re-fixated on the iliac crest. Discussion: Emergent surgical management of TAWH is often preferred due to high incidence of associated intra-abdominal lacerations. These settings are not always favorable for mesh placement. Some data suggest a higher recurrence rate for hernias without mesh augmentation and repair within the acute posttraumatic period. Conservative management poses the risk of incarceration and hernia defect enlargement. A delayed repair can be considered if the patient is hemodynamically stable, no associated visceral lacerations are present and the defect is large enough to reduce the risk of incarceration. It has the advantage of mesh placement in healthy tissue. Conclusions: A delayed laparoscopic repair seems a safe and valid option allowing larger mesh placement. Additional fascia closure of muscle fixation can be done granting more reinforcement and smaller incision needs and thus less postoperative pain.

USE OF A CALCIUM PARTICULATE AND FEEDING TIME ALONE OR IN COMBINATION WITH 25-HYDROXYHOLECALCIFEROL TO REDUCE FRACTURE SUSCEPTIBILITY IN LAYING HENS

The aim of this article is to present the possibility of reducing sternum fractures (KBF) in laying hens by using calcium particulate 2 hours before turning off the lights (CaT), alone or in combination with 25-hydroxyholecalciferol (Hyd). For the experiment, a total of 240 birds were used that were exposed to one of four treatment combinations in a 2X2 factorial design (Factor 1: CaT+ or Control (CaT-); Factor 2: Hyd vs. Control (Hyd-). All birds were housed in a commercial aviary until 33 weeks of age when they were moved to a test barn and randomly assigned to one of the eight pens (30 hens/pen). After one week of habituation to the novel housing, all birds began to receive one of the four treatment combinations (n = 2 replicate pens/treatment combinations). The ability of the treatment combinations to reduce fracture susceptibility was tested using an ex vivo impact testing protocol. After 39 weeks of age the keels were removed and scored for damage using an established three-point severity scale. The likelihood of an experimental fracture occurring in the CaT-/Hyd- was 3.6 times more likely compared to the CaT+ /Hyd+ treatment (1.1 to 5.8).

Validation of the modified AO sternum classification system.

The Arbeitsgemeinschaft für Osteosynthesefragen (AO) foundation along with the Orthopaedic. Trauma Association (OTA) introduced a new classification for sternal fractures in 2018 aiming to provide greater uniformity and clinical utility for the surgical community. A previous validation study identified some critical issues such as the differentiation between type A and B fractures and localization of the fracture either in the manubrium or in the body. Due to the moderate agreement in inter- and intra-observer variability, some modifications were proposed in order to improve the performance of the classification. The aim of this study was to re-assess the inter- and intra-observer variability after adding modifications to the classification. Our hypothesis was that a significative improvement of inter- and intra-observer variability could be achieved. Twenty computed tomography (CT) scans of patients with sternal fractures were analyzed by six. Junior and six senior surgeons independently. Two assessments were performed with an interval of 6weeks. The kappa (K) value was calculated in order to assess inter- and intra-observer variability. The overall mean kappa value for inter-observer variability improved from 0.364 to 0.468 (p < 0.001). Inter-observer variability mean for location was 0.573 (SD 0.221) and for type was 0.441 (SD: 0.181). Intra-observer variability showed a mean of 0.703 (SD: 0.153) with a statistic significant improvement when compared to the previous study (mean 0.414, SD: 0.256, p < 0.001). By modifying the AO/OTA classification of sternal fractures, the inter- and intra-observer variability improved and now shows moderate to substantial agreement.

Sternal Fractures in Blunt Chest Trauma: Retrospective Analysis of 330 Cases.

To analyse the range of injuries associated with sternal fracture (SF) and their clinical features and outcomes. Observational study. Department of Emergency Medicine, Faculty of Medicine, Selcuk University, Konya, Turkey, from July 2010 to July 2020. Sternal fractures were considered in 330 patients with blunt trauma during the study period. They were categorised according to the Johnson and Branfoot classification and the Arbeitsgemeinschaft fur Osteosynthesefragen / Orthopaedic Trauma Association classification. Demographic data were collected, including age, gender, mechanism of injury, associated injuries, and the length of hospital stay. During the 10-year study period, a total of 4024 thoracic trauma patients were admitted to the emergency department. Of these, 330 (8.2%) had a sternal fracture. The median age of the patients was 41 (8-90) years, and 72.7% were male. Isolated sternal fractures occurred in 93 patients (28.2%). An additional thoracic injury was observed in 74 patients (22.4%) included in the study, and an accompanying extrathoracic injury was observed in 34 patients (10.3%). In 129 patients (39.1%), both thoracic and extrathoracic pathologies were detected, in addition to SF. The mortality rate among patients with isolated sternal fracture was 1.1%; the mortality rate among patients with sternal fracture accompanied by additional pathologies was 6.6%. Sternal fractures are frequently associated with other injuries. Although isolated sternal fracture has a good prognosis, careful evaluation and clinical observation are essential for additional injuries. Emergency medicine, Sternal fracture, Chest trauma.

P325 CARDIAC SARCOIDOSIS…TYPICAL CLINICAL PRESENTATION

Abstract We report the case of a 50–year–old man without previous medical hystory who was admitted to our department for recurrent syncopes for several months. Throughout the 24 hours ECG Holter it has been underlined several advanced atrioventricular block episodes, hence the patient underwent to definitive pacemaker implant. After 3 months, due to sustained ventricular tachycardia, the patient incurred a out–of–hospital cardiac arrest; the patient was subjeced to cardio pulmonary resuscitation with the restoration of the sinus rithm following defibrillation. Unfortunatly, due to the resuscitation maneuvers, sternal fracture resulted. During the hospitalization in the Cardiology department, he underwent coronary angiography wich showed non significant lesions. Cardiac Magnetic Resonance was also performed among the tests. The examination was found to be particularly hard to understand due to the presence of the sternal injury that deformed the pectus and affected dynamics of the right ventricle, causing systolic bulging of the subtricuspid region of the right ventricular wall. During the dynamic sequences, there was a mild bi–ventricular reduction in systolic function. In post contrast imaging, extended transmural LGE of the basal interventricular septum and right ventricular wall, as well as multifocal involvement of the left ventricle were found. Examination was not of univolcal interpretation: the patient was tranferred to another Center to perform MR PET wich was found to be strongy suggestive of sarcoidosis, later confirmed by extra cardiac biopsy. For this reason an ICD upgrade was performed along side the immunosoppressive therapy. Sarcoidosis is an inflammatory disease characterized by the presence of noncaseous granulomas in one or more organs or tissues; at the cardiac level it can “mimic” different cardiomyopathies as an insidious diagnosis. The presence of a post–traumatic pectus excavatum leads to dyskinesia of the rignt venticular wall, reduction of the bi–ventricular systolic funcion combine with an extensive late enhancement could suggest arrhytmogenic dysplasia with bi–ventricular involvement. However, by focusing on the clinical presentation (in particular the onset charaterized by unexplained advanced AV block in a young and healthy subjet and subsequent ventricular arrhytmias), through a multimodal and multidisciplinary imaging approach it was posible to diagnose sarcoidosis with cardiac involvement and refer the patient to adequate therapy.

Road traffic accident-related thoracic trauma: Epidemiology, injury pattern, outcome, and impact on mortality-A multicenter observational study.

Thoracic trauma is a major cause of death in trauma patients and road traffic accident (RTA)-related thoracic injuries have different characteristics than those with non-RTA related thoracic traumas, but this have been poorly described. The main objective was to investigate the epidemiology, injury pattern and outcome of patients suffering a significant RTA-related thoracic injury. Secondary objective was to investigate the influence of serious thoracic injuries on mortality, compared to other serious injuries. We performed a multicenter observational study including patients of the Rhône RTA registry between 1997 and 2016 sustaining a moderate to lethal (Abbreviated Injury Scale, AIS≥2) injury in any body region. A subgroup (AISThorax≥2 group) included those with one or more AIS≥2 thoracic injury. Descriptive statistics were performed for the main outcome and a multivariate logistic regression was computed for our secondary outcome. A total of 176,346 patients were included in the registry and 6,382 (3.6%) sustained a thoracic injury. Among those, median age [IQR] was 41 [25-58] years, and 68.9% were male. The highest incidence of thoracic injuries in female patients was in the 70-79 years age group, while this was observed in the 20-29 years age group among males. Most patients were car occupants (52.3%). Chest wall injuries were the most frequent thoracic injuries (62.1%), 52.4% of which were multiple rib fractures. Trauma brain injuries (TBI) were the most frequent concomitant injuries (29.1%). The frequency of MAISThorax = 2 injuries increased with age while that of MAISThorax = 3 injuries decreased. A total of 16.2% patients died. Serious (AIS≥3) thoracic injuries (OR = 12.4, 95%CI [8.6;18.0]) were strongly associated with mortality but less than were TBI (OR = 27.9, 95%CI [21.3;36.7]). Moderate to lethal RTA-related thoracic injuries were rare. Multiple ribs fractures, pulmonary contusions, and sternal fractures were the most frequent anatomical injuries. The incidence, injury pattern and mechanisms greatly vary across age groups.

Surgical Infection Society: Chest Wall Injury Society Recommendations for Antibiotic Use during Surgical Stabilization of Traumatic Rib or Sternal Fractures to Reduce Risk of Implant Infection.

Background: Surgical stabilization of rib fractures is recommended in patients with flail chest or multiple displaced rib fractures with physiologic compromise. Surgical stabilization of rib fractures (SSRF) and surgical stabilization of sternal fractures (SSSF) involve open reduction and internal fixation of fractures with a plate construct to restore anatomic alignment. Most plate constructs are composed of titanium and presence of this foreign, non-absorbable material presents opportunity for implant infection. Although implant infection rates after SSRF and SSSF are low, they present a challenging clinical entity often requiring prolonged antibiotic therapy, debridement, and potentially implant removal. Methods: The Surgical Infection Society's Therapeutics and Guidelines Committee and Chest Wall Injury Society's Publication Committee convened to develop recommendations for antibiotic use during and after surgical stabilization of traumatic rib and sternal fractures. Clinical scenarios included patients with concomitant infectious processes (sepsis, pneumonia, empyema, cellulitis) or sources of contamination (open chest, gross contamination) incurred as a result of their trauma and present at the time of their surgical stabilization. PubMed, Embase, and Cochrane databases were searched for pertinent studies. Using a process of iterative consensus, all committee members voted to accept or reject each recommendation. Results: For patients undergoing SSRF or SSSF in the absence of pre-existing infectious process, there is insufficient evidence to suggest existing peri-operative guidelines or recommendations are inadequate. For patients undergoing SSRF or SSSF in the presence of sepsis, pneumonia, or an empyema, there is insufficient evidence to provide recommendations on duration and choice of antibiotic. This decision may be informed by existing guidelines for the concomitant infection. For patients undergoing SSRF or SSSF with an open or contaminated chest there is insufficient evidence to provide specific antibiotic recommendations. Conclusions: This guideline document summarizes the current Surgical Infection Society and Chest Wall Injury Society recommendations regarding antibiotic use during and after surgical stabilization of traumatic rib or sternal fractures. Limited evidence exists in the chest wall surgical stabilization literature and further studies should be performed to delineate risk of implant infection among patients undergoing SSSRF or SSSF with concomitant infectious processes.

Association of ‘Low Risk’ Fractures With Abuse in Young Children

Association of ‘Low Risk’ Fractures With Abuse in Young Children

Closure-related complications after median sternotomy in cats: 26 cases (2010-2020).

ObjectivesThe aim of this study was to determine closure-related complications and outcome after median sternotomy (MS) in cats.MethodsThis was a retrospective, multicentric study. The medical records of cats undergoing MS from six referral hospitals were reviewed (2010–2020). Data retrieved included signalment, history, presenting complaints, surgery, patient outcomes and complications. Follow-up was performed via patient records and email/telephone contact with both owners and referring veterinarians. Descriptive statistics were performed.ResultsData on 36 cats were collected; four were excluded due to insufficient follow-up and six died less than 5 days after surgery. Twenty-six cats survived to discharge (survival rate 81%). Three cats had a full sternotomy (FS) performed and 23 cats a partial sternotomy (PS). Of the cats that underwent a PS, six included the manubrium (PSM) and three included the xyphoid process. For 14 cats, the length of sternotomy was unknown. Sternotomy closure was performed with suture in all cats. Two cats (7.7%) developed closure-related complications, both after PSM, during the long-term follow-up, one mild, slightly displaced sternal fracture and one severe, sternal dehiscence (without skin wound dehiscence) requiring revision surgery. No seroma, surgical site infection or wound dehiscence occurred. The most common reason for MS was the presence of a thoracic mass (17/26; 65%), with thymoma being the most common (11/17; 65%).Conclusions and relevanceMS has a low closure-related complication risk in cats when compared with dogs. Complications in cats present differently to what has been previously described in dogs.

Features of management of patients with fractures of the sternum

Fractures of the sternum are rare types of injuries that usually occur because of damage to the anterior chest. Due to the high frequency of combined injuries of internal organs, the mortality rate in patients with sternum fractures can reach 45 %. Despite this, the treatment of sternum fractures is a poorly understood topic. Therefore, this study was aimed at analyzing the features of managing patients with sternum fractures.

805 Case Report: Atrial Perforation in the Setting of Electrical Injury and Subsequent Cardiopulmonary Resuscitation

IntroductionElectrical injuries cause 500 to 1000 deaths per year in the United States and are the fourth leading cause of death in the workplace. Rates and types of cardiac complication secondary to electrical injuries vary widely throughout the literature. Case reports describing cardiac perforation in the setting of electrical injury are exceedingly sparse. To our knowledge, there are no documented cases of cardiac perforation as a direct result of electrical injury.MethodsThis is a case report and review of relevant literature.ResultsCase Description:We present a case of myocardial perforation in the setting of high voltage electrical injury. An otherwise healthy 46-year old male sustained a 13.8 kV electrical. Resuscitation included bystander cardiopulmonary resuscitation (CPR), defibrillation by emergency medical responders, finger thoracostomies and massive transfusion protocol in the trauma bay, and finally emergent sternotomy and repair of two injuries to the right atrial appendage. Given this patient’s pattern of injury, including a sternal fracture and bilateral upper anterior rib fractures, the etiology of his right atrial perforation is more likely due to mechanical injury from CPR instead of thermal or electrical injury to the myocardium. However, intraoperative findings confound this theory as no defects were identified in the pericardium of the mediastinal pleura during the operation. This would argue against mechanical injury during CPR. However, the presence of a left hemothorax may could indicate that a pericardial injury was missed in the operation. We argue that the most likely cause of injury is mechanical perforation of the pericardium and myocardium during CPR with a possible missed pericardiotomy during surgical exploration. An alternative hypothesis is an isolated electrical injury to the myocardium and left hemothorax from rib fractures without communication between the two cavities. This patient expired on postoperative day two due to anoxic brain injury.ConclusionsThis case highlights myocardial injury as a rare but lethal complication of high voltage electrical injury and serves as a reminder that cardiac perforation and hemodynamic collapse due to hypovolemic shock can compound and complicate the resuscitation and management of a patient with electrical injury. Further, the widely varying data regarding cardiac complications secondary to electrical injury warrants further investigation and large-scale prospective data.

Feasibility and cost-effectiveness of surgical stabilization of traumatic rib and sternum fractures with off-label utilization of cranio-maxillo-facial surgery titanium implants: Case series

Objectives: Recent evidence showed improved outcomes in surgical fixation, compared to conservative management, of flail chest and severe non-flail rib fractures patterns. The dedicated rib fixation systems are expensive and not available in most hospitals. This study aims to establish the feasibility of surgical stabilization of traumatic rib and sternum fractures with off-label utilization of cranio-maxillo-facial surgery titanium implants. Methods: Case series where data of patients, who underwent surgical stabilization of traumatic rib or sternum fractures with off-label utilization of cranio-maxillo-facial surgery titanium implants at Bufalini Hospital in Cesena, Italy, were retrospectively collected. Results: From August 2018 to June 2020, 13 patients were included. The mean operative time was 87.5 minutes (median ± SD: 85 ± 27.1). Post-operative complications were: pneumonia (46.2%), sepsis (7.7%) and superficial wound infection (15.4%). No patients underwent reintervention. No infection or displacement of plates occurred. The costs of the most utilized titanium plates and screws in our series (∅ 2.3–2.5 mm KLS Martin®) were 122–245 € for one plate and, 13 € for a pack of five screws. Conclusions: The present study showed the feasibility of the off-label use, for rib stabilization, of devices from cranio-maxillo-facial surgery, usually easily available in hospitals and, in particular, in trauma centers, also without elective thoracic surgery departments. These devices are cheaper than the most widely utilized rib fixation systems and, being easily available in hospitals, could be used in urgent settings and could avoid the delay of rib fixation if dedicated thoracic fixation systems are not available. They could have a role also in low-income countries.

Blunt Cardiac Injury in Patients With Sternal Fractures.

BackgroundBlunt cardiac injury (BCI) is a possible consequence of sternal fractures (SF). There is a scarcity of studies addressing BCI in patients with different types of SF and with pre-existing cardiac conditions. The goal of this study was to delineate diagnostic patterns of BCI in different cohorts of SF patients.MethodsThis retrospective cohort study included 380 blunt trauma patients admitted to two level 1 trauma centers between January 2015 and March 2020 with radiologically confirmed SF. Electrocardiography, cardiac enzymes and echocardiography were evaluated for BCI diagnosis. Analyzed variables included: age, comorbidities, injury severity score, Glasgow coma score, type of SF (isolated, combined, displaced), incidence of traumatic brain injury, co-injuries, retrosternal hematoma, intensive care unit admissions, hospital lengths of stay, and mortality.ResultsIn 380 SF patients there were 250 (66%) females and 130 (34%) males and the mean age was 63 years old. Electrocardiography was done in all patients, cardiac enzymes in 234 (62%) and echocardiography in 181 (48%). BCI was diagnosed in 19 (5%) of patients, all having combined SF. BCI patients had higher injury severity score (mean 18.4) and 14 (74%) had pulmonary co-injuries. Multivariable analysis confirmed pulmonary co-injuries as a statistically significant predictor of BCI (p<0.001). BCI patients compared to no BCI patients had all three tests (electrocardiography, cardiac enzymes and echocardiography) performed statistically more often (90% vs 36%, p<0.001). SF patients with pre-injury cardiac comorbidities had similar incidence of BCI as without cardiac comorbidities (5% vs 6%, p=0.6). In SF patients with traumatic brain injury, cardiac enzymes (troponin, creatine kinase) were elevated significantly more often compared to patients without traumatic brain injury (58% vs 38%, p=0.02). SF displacement or retrosternal hematoma presence were not associated with BCI. Mortality in SF patients with BCI versus without was not statistically different (16 vs 9%, p=0.4).ConclusionsBlunt cardiac injury is rare in patients with SF. Higher degree of BCI suspicion must be applied in combined SF patients, especially those with pulmonary co-injuries. Cardiac comorbidities did not affect the rate of BCI. Echocardiography for BCI diagnosis is essential in SF patients with traumatic brain injury, as cardiac enzymes may be less informative, however is less important in isolated SF patients. Performing all three diagnostic tests in combined SF patients improves the accuracy of BCI diagnosis.

Leriche syndrome diagnosed due to polytrauma: a case report

BackgroundLeriche syndrome is caused by atherosclerosis and is often characterized by symptoms such as intermittent claudication and numbness and coldness of the lower limbs. Its exact prevalence and incidence are unknown because it is a rare disease. We report a case of Leriche syndrome diagnosed incidentally on trauma pan-scan computed tomography (CT).Case presentationA 61-year-old Asian male was driving a passenger car and had a head-on collision with a dump truck that required an emergency call. The patient was transported to our hospital in a doctor’s helicopter. Physical examination revealed the following vital signs: respiratory rate, 23 breaths per min; SpO2, 98% under a 10-L administration mask; pulse rate, 133 beats per min; blood pressure, 142/128 mmHg; Focused Assessment with Sonography for Trauma, positive; Glasgow Coma Scale assessment, E3V5M6; and body temperature, 35.9 °C.Trauma pan-scan CT showed bilateral mandibular fractures, bilateral multiple rib fractures, bilateral pneumothorax, sternal fractures, hematoma around thoracic spine, small bowel perforation, mesenteric injury, right clavicle fracture, right ankle debridement injury, and thrombotic occlusion from just above the abdominal aortic bifurcation to the bilateral common iliac arteries. Although thrombotic occlusion needed to be differentiated from traumatic aortic injury, the presence of collateral blood vessels led to the diagnosis of Leriche syndrome, and conservative treatment was performed.Damage control surgery was required for the small bowel injuries. From the second day of admission, the patient was treated with continuous intravenous heparin and prostaglandin preparations. However, impaired blood flow and reperfusion injury in the right lower extremity progressed. On the fifth day of admission, right thigh amputation was performed. The patient required renal replacement therapy for 2 weeks starting from the third day of admission.ConclusionsIn this case, conservative therapy was initially chosen for Leriche syndrome. However, the complex factors in the acute phase of trauma led to development of hemorrhagic necrosis, requiring amputation of the lower extremity. Our findings indicate the need to carefully consider the unique factors affecting Leriche syndrome patients when considering treatment indications and choices for trauma.

Computed-Tomography as First-line Diagnostic Procedure in Patients With Out-of-Hospital Cardiac Arrest.

BackgroundMortality after out-of-hospital cardiac arrest (OHCA) with return of spontaneous circulation (ROSC) remains high despite numerous efforts to improve outcome. For patients with suspected coronary cause of arrest, coronary angiography is crucial. However, there are other causes and potentially life-threatening injuries related to cardiopulmonary resuscitation (CPR), which can be detected by routine computed tomography (CT).Materials and MethodsAt Hannover Medical School, rapid coronary angiography and CT are performed in successfully resuscitated OHCA patients as a standard of care prior to admission to intensive care. We analyzed all patients who received CT following OHCA with ROSC over a three-year period.ResultsThere were 225 consecutive patients with return of spontaneous circulation following out-of-hospital cardiac arrest. Mean age was 64 ± 13 years, 75% were male. Of them, 174 (77%) had witnessed arrest, 145 (64%) received bystander CPR, and 123 (55%) had a primary shockable rhythm. Mean time to ROSC was 24 ± 20 min. There were no significant differences in CT pathologies in patients with or without ST-segment elevations in the initial ECG. Critical CT findings qualifying as a potential cause for cardiac arrest were intracranial bleeding (N = 6), aortic dissection (N = 5), pulmonary embolism (N = 17), pericardial tamponade (N = 3), and tension pneumothorax (N = 11). Other pathologies were regarded as consequences of CPR and relevant for further treatment: aspiration (N = 62), rib fractures (N = 161), sternal fractures (N = 50), spinal fractures (N = 11), hepatic bleeding (N = 12), and intra-abdominal air (N = 3).ConclusionEarly CT fallowing OHCA uncovers a high number of causes and consequences of OHCA and CPR. Those are relevant for post-arrest care and are frequently life-threatening, suggesting that CT can contribute to improving prognosis following OHCA.

Operative versus non-operative management of rib fractures in flail chest after cardiopulmonary resuscitation manoeuvres.

OBJECTIVESBlunt chest trauma after mechanical resuscitation manoeuvres appears to have a significant impact on the often complicated course. Due to a lack of data in the literature, the purpose of this study was to investigate the feasibility and immediate outcome of chest wall stabilization for flail chest in this vulnerable patient population.METHODSWe retrospectively reviewed the medical records of patients after cardiopulmonary resuscitation between January 2014 and December 2018 who were diagnosed with flail chest. We attempted to compare patients after surgery with those after conservative treatment.RESULTSOf a total of 56 patients with blunt chest trauma after mechanical resuscitation and after coronary angiography, 25 were diagnosed with flail chest. After the exclusion of 2 patients because of an initial decision to palliate, 13 patients after surgical stabilization could be compared with 10 patients after conservative therapy. Although there was no significant difference in the total duration of ventilatory support, there was a significant advantage when the time after stabilization to extubation was compared with the duration of ventilation in the conservative group. The presence of pulmonary contusion, poor Glasgow Coma Scale score or the development of pneumonia negatively affected the outcome, but additional sternal fracture did not.CONCLUSIONSSurgical stabilization for chest wall instability is well tolerated even by this vulnerable patient population. Our results should be used for further randomized controlled approaches. It is necessary to evaluate the situation with all parameters in an interdisciplinary manner and to decide on a possible surgical therapy at an early stage if possible.

The effect of skeletal muscle area and attenuation in patients with sternum fracture due to blunt chest trauma.

This study aims to retrospectively investigate the imaging features of patients with sternum fracture (SF) and concomitant organ injuries. We also aimed to evaluate the potential prognostic effect of skeletal muscle area (TMA) and muscle attenuation (MuA) values. Computed tomography (CT) images of patients with SF were re-evaluated by two observers (Observer-1 and 2). Observer-3 has measured TMA and MuA values. Observer-1 has repeated the measurements blindly to the first measurement results to evaluate the inter-observer agreement. The length of hospital stay, death, hemiplegia, or quadriplegia were investigated from the archives. Mann-Whitney U-test or Student's t-test was used to investigate the relationship between linear variables. The intraclass correlation coefficient (ICC) score was used to evaluate the interobserver agreement. Logistic regression analysis was used to estimate the relative effect of variables by calculating unadjusted odds ratios (ORs) for categorical outcomes. Sixty-five patients had SF and 53 patients had SF and concomitant organ injuries. The most common injuries accompanying SF were rib fracture (73.58%) and lung contusion (60.38%). Manubrium fracture was the most common fracture location (52.3%), and 18 patients (27.7%) had displaced SF. Eight patients (15.1%) were discharged with plegia and five (9.4%) died. Hemothorax, displaced SF and decreased MuA were predictors of prolonged hospital stay, and the presence of cardiac contusion, displaced SF, hemothorax, and vertebra body fracture were independent factors for death. The presence of a displaced SF and decreased MuA value are important prognostic factors in patients with SF.
