Intervention effect of injury control orthopedic strategy on fat embolism syndrome associated with long shaft fracture of lower limb / 中国骨伤

OBJECTIVE@#To observe the intervention effect of damage control orthopaedic(DCO) strategy on fat embolism syndrome(FES) associated with long shaft fracture of lower limbs.@*METHODS@#Retrospective analysis was made on the clinical data of 163 patients with FES associated with lower limb long shaft fractures admitted from January 2015 to May 2021. They were divided into two groups based on the time point of implementing DCO strategy in January 2018. Total of 92 patients were admitted from January 2015 to December 2017 as the control group, and other 71 patients were admitted from January 2018 to May 2021 as the intervention group. The hospital mortality, arterial oxygen saturation (SaO2), arterial partial pressure of oxygen (PaO2) and oxygenation index (OI), hemoglobin (Hb), platelet count(PLT), Harris score of hip joint, HSS score of knee joint, AOFAS score of ankle joint, clinical efficacy and complications were observed and compared between two groups.@*RESULTS@#Total of 163 patients were followed up for 12 to 18 months with an average of (16.91±1.22) months. The in-hospital mortality rate in the intervention group was 2.82% (2/71), and that in the control group was 16.30% (15/92), the difference between two groups was statistically significant(χ2=6.455, P<0.05). After the intervention, SaO2, PaO2 and OI in two groups were higher than those before the intervention(P<0.05), and after the intervention, SaO2, PaO2 and OI in two groups were statistically significant(P<0.05). Hb and PLT in two groups after intervention were higher than those before intervention (P<0.001), and there was statistically significant difference in Hb and PLT between two groups after intervention (P<0.05). The Harris score of hip joint, HSS score of knee joint and AOFAS score of ankle joint in both groups after 3 months of treatment were better than those before treatment (P<0.05). The total clinical effective rate of the intervention group was higher than that of the control group(χ2=4.194, P<0.05). The total incidence of complications in the intervention group was lower than that in the control group(χ2=4.747, P<0.05).@*CONCLUSION@#DCO strategy is helpful to reduce the in-hospital mortality of patients with FES associated with long shaft fracture of lower extremities, eliminate FES symptoms and stabilize vital signs, gain time advantage for phase Ⅱ definitive surgery, and has significant clinical intervention effect, which is worth popularizing.

Research Status and Prospects of Non-Traumatic Fat Embolism in Forensic Medicine / 法医学杂志

In the practice of forensic pathology, fat embolism is one of the common causes of death, which can be divided into two categories: traumatic and non-traumatic. Non-traumatic fat embolism refers to the blockage of small blood vessels by fat droplets in the circulatory blood flow caused by non-traumatic factors such as underlying diseases, stress, poisoning and lipid metabolism disorders. At present, it is believed that the production of non-traumatic fat embolism is related to the disturbance of lipid metabolism, C-reactive protein-related cascade reaction, the agglutination of chylomicron and very low-density lipoprotein. The forensic identification of the cause of death of non-traumatic fat embolism is mainly based on the case, systematic autopsy, HE staining and fat staining, but it is often missed or misdiagnosed by forensic examiners because of its unknown risk factors, hidden onset, the difficulty of HE staining observation and irregular implementation of fat staining. In view of the lack of attention to non-traumatic fat embolism in forensic identification, this paper reviews the concepts, pathophysiological mechanism, research progress, existing problems and countermeasures of non-traumatic fat embolism, providing reference for forensic scholars.

Embolismo graso fulminante por lipoinyección glútea. Reporte de un caso con enfoque Médico Legal / Fulminant fat embolism due to gluteal lipoinjection. Report of a case with a Medical Legal approach

Resumen La liposucción es uno de los procedimientos estéticos que se realizan con mayor frecuencia a nivel mundial, con una baja incidencia de complicaciones y una mortalidad de 20 por cada 100 000 procedimientos y cuando se realiza en conjunto con una lipoinyección glútea la principal causa de muerte el embolismo graso. Se presenta el caso de una femenina de 32 años, sin patologías crónicas conocidas, la cual se asistió a un centro médico para que le realizaran una liposucción con lipoinyección glútea y falleció casi al finalizar la cirugía; en la autopsia Médico Legal se observó la presencia de material de aspecto adiposo en el tronco principal de la arteria pulmonar y en sus ramificaciones, en las cuales se obstruía por completo el lumen, mediante un estudio histopatológico se confirmó el diagnostico de embolismo graso, el cual se estableció como causa de muerte. Se realizó una revisión de la literatura sobre embolismo graso asociado a liposucción con lipoinyección glútea.

Abstract Liposuction is one of the most frequently performed cosmetic procedures worldwide, with a low incidence of complications and a mortality of 20 per 100 000 procedures, and when it is performed in conjunction with gluteal lipoinjection, the main cause of death is fat embolism. This article presents a case of a 32-year-old female, with no known chronic pathologies, who was attended at a medical center to undergo liposuction with gluteal lipoinjection and died almost at the end of the surgery; In the Medico-Legal autopsy, the presence of adipose-like material was observed in the main trunk of the pulmonary artery and in its ramifications, in which the lumen was completely obstructed, a histopathological study confirmed the diagnosis of fat embolism, which was established as the cause of death. A review of the literature about fat embolism associated with liposuction with gluteal lipoinjection was made.

Sudden death caused by Clostridium perfringens sepsis presenting as massive intravascular hemolysis

An 80-year-old Japanese woman with diabetes mellitus was admitted with gastrointestinal symptoms and pyrexia. At presentation, liver abscesses and severe hemolytic anemia were noted. Before detailed diagnostic evaluation and adequate treatment, she suddenly died 2.5 hours after admission. The autopsy and bacteriological examinations revealed liver abscesses and massive intravascular hemolysis caused by Clostridium perfringens as well as other miscellaneous critical pathological findings, including acute renal tubular necrosis, lung edema, and pulmonary fat embolism. In this article, the detailed autopsy results are described and clinicopathologic characteristics on Clostridium perfringens-related sudden death are discussed with a review of the literature.

COVID-19 suspicion revealed to be fat embolism syndrome

The novel Coronavirus, named SARS-CoV-2, responsible of the COVID-19 is now causing a pandemic. Detecting all possible cases and eliminating differential diagnoses in front of any acute respiratory distress has become a daily challenge for doctors around the world. We believe that non-COVID patients are the hidden victims of the actual health problematic. We report from this manuscript the case of a patient with fat embolism syndrome that has been suspected as COVID-19

Un caso de síndrome de embolia grasa: tratamiento y rehabilitación neurológica y cognitiva / A case report off at embolism syndrome: Treatment and neurological and cognitive rehabilitation

Resumen Se reporta el proceso de recuperación y rehabilitación neurológica y cognitiva de una mujer joven que desarrolló un síndrome de embolia grasa con repercusiones neurológicas, después de sufrir un politraumatismo. La paciente era una mujer de 21 años de edad con fractura cerrada de húmero y fémur izquierdos, que presentó un síndrome de embolia grasa, neumotórax izquierdo e hipertensión pulmonar, en las primeras 24 horas después de un accidente. Estuvo hospitalizada un mes y quedó con varios déficits neurológicos centrales, como infartos 'lacunares' y necrosis cortical laminar occipital, así como limitaciones en la bipedestación, la marcha, la visión y las funciones cognitivas. A partir del primer mes después del alta hospitalaria, se comenzó un proceso integral de rehabilitación neurológica y cognitiva en casa, y posteriormente, en una unidad médica de rehabilitación. Durante los primeros dos años después del accidente, la paciente recibió estimulación sensorial, sensoperceptiva y motora, así como rehabilitación motora y visual intensiva. Una vez se recuperó físicamente, se inició un proceso de rehabilitación neuropsicológica. Seis años después del accidente, la paciente terminó sus estudios universitarios y hoy está laboralmente activa. El proceso de rehabilitación neurológica es complejo, individual y difícil, aunque no imposible, y no se puede estandarizar un patrón de recuperación para todos los pacientes. Si bien existe la recuperación espontánea, la cual se da en los primeros seis meses, el caso aquí reportado demuestra que, en la fase crónica, la recuperación se puede lograr, pero requiere de evaluaciones y técnicas coordinadas de rehabilitación neurológica.

Abstract We report the neurological and cognitive recovery and rehabilitation process in a young woman who developed a fat embolism syndrome with neurological repercussions secondary to multiple trauma. The patient was a 21-year-old woman with a closed fracture of the left humerus and femur. She developed fat embolism syndrome, left pneumothorax and pulmonary hypertension in the first 24 hours after the accident. After one month of hospitalization, the patient had several central neurological deficits such as lacunar infarcts and occipital laminar cortical necrosis, as well as limitations in standing, walking, vision, and cognitive functions. An integral process of neurological and cognitive rehabilitation--first at home and later in a medical rehabilitation unit-- was carried out from the first month after being released from the hospital. During the first two years after the accident, the patient received sensory and motor stimulation, motor rehabilitation, and intensive visual rehabilitation. Once recovered physically, a process of neuropsychological rehabilitation began. Six years after the accident, the patient finished her university studies and she is working actively. The neurological rehabilitation process is complex, individual and difficult, but not impossible, and a recovery pattern cannot be standardized for all patients. Although there is spontaneous recovery, which occurs in the first six months, the case here reported shows that in the chronic phase recovery can be achieved but requires evaluations and coordinated techniques of neurological rehabilitation.

Sudden death caused by pulmonary fat embolism in a patient with miliary tuberculosis

An 84-year-old Japanese woman with myelodysplastic syndrome was admitted with pyrexia and dyspnea, but died suddenly during diagnostic evaluation. The autopsy revealed miliary tuberculosis in addition to myelodysplastic syndrome in the bone marrow. The immediate cause of the patient's sudden death was pulmonary fat embolism derived from bone marrow necrosis. This case shows that the infiltration of the myelodysplastic bone marrow by tuberculosis and consequent bone marrow necrosis and fat embolism can be the cause of sudden death. In this article, we report the autopsy results of this unusual cause of sudden death, and discuss tuberculosis-related sudden death with a review of the literature.

Effectiveness of Autologous Fat Graft in Treating Fecal Incontinence

PURPOSE: The most common risk factor for fecal incontinence (FI) is obstetric injury. FI affects 1.4%–18% of adults. Most patients are unaware when they are young, when symptoms appear suddenly and worsen with aging. Autologous fat graft is widely used in cosmetic surgical field and may substitute for injectable bulky agents in treating FI. Authors have done fat graft for past several years. This article reports the effectiveness of the fat graft in treating FI and discusses satisfaction with the procedure. METHODS: Fat was harvested from both lateral thighs using 10-mL Luer-loc syringe. Pure fat was extracted from harvests and mixed with fat, oil, and tumescent through refinement. Fats were injected into upper border of posterior ano-rectal ring, submucosa of anal canal and intersphincteric space. Thirty-five patients with FI were treated with this method from July 2016 to February 2017 in Busan Hangun Hospital. They were 13 male (mean age, 60.8 years) and 22 female patients (mean age, 63.3 years). The Wexner score was checked before procedure. We evaluated outcome in outpatients by asking the patients. For 19 patients we checked the Wexner score after procedure. RESULTS: Symptom improved in 29 (82.9%), and not improved in 6 (17.1%). In 2 of 6 patients, they felt better than before procedure, although not satisfied. No improvement in 4. Mean Wexner score was 9.7 before procedure. There were no serious complications such as inflammation or fat embolism. CONCLUSION: Autologous fat graft can be an effective alternative treatment for FI. It is safe and easy to perform, and cost effective.

Clinical characteristics and management of patients with fat embolism syndrome in level I Apex Trauma Centre / 中华创伤杂志(英文版)

PURPOSE@#Fat embolism syndrome (FES) is systemic manifestation of fat emboli in the circulation seen mostly after long bone fractures. FES is considered a lethal complication of trauma. There are various case reports and series describing FES. Here we describe the clinical characteristics, management in ICU and outcome of these patients in level I trauma center in a span of 6 months.@*METHODS@#In this prospective study, analysis of all the patients with FES admitted in our polytrauma intensive care unit (ICU) of level I trauma center over a period of 6 months (from August 2017 to January 2018) was done. Demographic data, clinical features, management in ICU and outcome were analyzed.@*RESULTS@#We admitted 10 cases of FES. The mean age of patients was 31.2 years. The mean duration from time of injury to onset of symptoms was 56 h. All patients presented with hypoxemia and petechiae but central nervous system symptoms were present in 70% of patients. The mean duration of mechanical ventilation was 11.7 days and the mean length of ICU stay was 14.7 days. There was excellent recovery among patients with no neurological deficit.@*CONCLUSION@#FES is considered a lethal complication of trauma but timely management can result in favorable outcome. FES can occur even after fixation of the fracture. Hypoxia is the most common and earliest feature of FES followed by CNS manifestations. Any patient presenting with such symptoms should raise the suspicion of FES and mandate early ICU referral.

Síndrome de hiperatividade simpática paroxística causada por síndrome da embolia gordurosa / Paroxysmal sympathetic hyperactivity syndrome caused by fat embolism syndrome

RESUMO A hiperatividade simpática paroxística representa uma complicação incomum, com potencial risco à vida, de lesões cerebrais graves, mais comumente de origem traumática. Seu diagnóstico clínico se baseia na manifestação recorrente de taquicardia, hipertensão, diaforese, taquipneia e, às vezes, febre, além de posturas distônicas. Os episódios podem ser induzidos por estímulos ou ocorrer de forma espontânea. É comum que ocorra subdiagnóstico desta síndrome, e o retardamento de seu reconhecimento pode aumentar a morbidade e a incapacidade em longo prazo. Evitar os desencadeantes e a farmacoterapia podem ter muito sucesso no controle desta complicação. A síndrome da embolia gordurosa é uma complicação rara, mas grave, das fraturas de ossos longos. Sinais neurológicos, petéquias hemorrágicas e insuficiência respiratória aguda são as características que constituem seu quadro clínico. O termo "embolia gordurosa cerebral" é estabelecido quando predomina o envolvimento neurológico. O diagnóstico é clínico, porém achados específicos de neuroimagem podem confirmá-lo. As manifestações neurológicas incluem diferentes graus de alteração da consciência, défices focais ou convulsões. Seu tratamento é de suporte, porém são possíveis desfechos favoráveis, mesmo nos casos com apresentação grave. Relatamos dois casos de hiperatividade simpática paroxística após embolia gordurosa cerebral, uma associação muito incomum.

ABSTRACT Paroxysmal sympathetic hyperactivity represents an uncommon and potentially life-threatening complication of severe brain injuries, which are most commonly traumatic. This syndrome is a clinical diagnosis based on the recurrent occurrence of tachycardia, hypertension, diaphoresis, tachypnea, and occasionally high fever and dystonic postures. The episodes may be induced by stimulation or may occur spontaneously. Underdiagnosis is common, and delayed recognition may increase morbidity and long-term disability. Trigger avoidance and pharmacological therapy can be very successful in controlling this complication. Fat embolism syndrome is a rare but serious complication of long bone fractures. Neurologic signs, petechial hemorrhages and acute respiratory failure constitute the characteristic presenting triad. The term cerebral fat embolism is used when the neurological involvement predominates. The diagnosis is clinical, but specific neuroimaging findings can be supportive. The neurologic manifestations include different degrees of alteration of consciousness, focal deficits or seizures. Management is supportive, but good outcomes are possible even in cases with very severe presentation. We report two cases of paroxysmal sympathetic hyperactivity after cerebral fat embolism, which is a very uncommon association.

A case of life-threatening intraoperative diffuse alveolar hemorrhage during a femur fracture operation with suspected fat embolism: A case report

Diffuse alveolar hemorrhage (DAH) is a rare manifestation of trauma or long bone fracture. A relationship between fat embolism and DAH has been reported. A 73-year-old female developed sudden cardiac arrest during a femur fracture operation. Cardiopulmonary resuscitation (CPR) was repeated for about 130 minutes. During CPR, blood was detected in the endotracheal tube. Diffuse patch ground glass opacity appearance and increased pulmonary artery with bulging of interventricular septum toward the left ventricle were detected on a chest computed tomography scan. After full supportive care including ventilator therapy, the patient's condition became stabilized and she was extubated after 7 days. We report a case of DAH in the course of a suspected fat embolism during femur fracture operation. Although DAH is a rare manifestation of fat embolism, early diagnosis and aggressive treatment likely can decrease morbidity and mortality.

Clinics in diagnostic imaging (184). Fat embolism syndrome (FES)

A 23-year-old Indian man presented with shortness of breath and new-onset confusion along with a rash on his chest on Postoperative Day 2, following internal fixation of his femur fracture. Although computed tomography pulmonary angiography was negative for filling defects in the pulmonary vasculature, it showed mosaic attenuation changes with some interlobular septal thickening. Magnetic resonance imaging of the brain showed patchy signal abnormalities, predominantly in the grey-white matter junction region with extensive susceptibility artefacts, consistent with petechial haemorrhages. The laboratory work-up showed thrombocytopenia and anaemia. A diagnosis of fat embolism syndrome was established, based on the clinical presentation combined with laboratory and imaging findings. The clinical and imaging features of fat embolism syndrome are discussed.

Sudden Deaths of Neonates Receiving Intravenous Infusion of Lipid Emulsion Contaminated with Citrobacter freundii

At an intensive care unit, four neonates died consecutively within 80 minutes. Citrobacter freundii was isolated from blood samples of the 4 patients. It was also cultured from the leftover SMOFlipid that had been infused intravenously into the patients. In this in vitro study, we evaluated the bacterial growth kinetics and change in size of fat globules in SMOFlipid contaminated with C. freundii. Following the growth of bacteria, pH of SMOFlipid decreased to < 6, and the number of fat globules larger than 5 µm increased. Pulmonary fat embolism is proposed as a possible cause of the sudden deaths as well as fulminant sepsis.

Bone marrow necrosis and fat embolism syndrome: a dreadful complication of hemoglobin sickle cell disease

Sickle cell disease encompasses a wide range of genotypic presentation with particular clinical features. The entity affects millions of people, particularly those whose ancestors came from sub-Saharan Africa and other countries in the Western Hemisphere, Saudi Arabia, and India. Currently, the high frequency of S and C genes reflects natural selection through the protection of heterozygotes against severe malaria, the high frequency of consanguineous marriages, improvement of some public health policies and the nutritional standards in the poorer countries where newborns are now living long enough to present for diagnosis and management. Although there is a high burden of the disease, in many countries, the new-born sickle cell screening test is being performed and is rendering an early diagnosis; however, it is still difficult for sickle cell patients to find proper treatment and adequate follow-up. Moreover, in many countries, patients are neither aware of their diagnosis nor the care they should receive to prevent complications; also, they do not receive adequate genetic counseling. Hemoglobin SC (HbSC) disease is the most frequent double sickle cell heterozygosis found in Brazil. The clinical course tends to be more benign with fewer hospitalizations compared with double homozygotic SS patients. However, HbSC patients may present severe complications with a fatal outcome. We report the case of a 36-year-old man who presented to the emergency care facility with symptoms consistent with the diagnosis of sickling crisis. The outcome was unfavorable and death occurred just hours after admission. The autopsy revealed a generalized vaso-occlusive crisis by sickled red cells, bone marrow necrosis, and fat embolism syndrome.

Embolismo graso asociado a liposucción y autoinjerto graso / Fat embolism associated with liposuction and fat autograft

Resumen:Se presenta el caso de una femenina de 30 años de edad, portadora de cirrosis por hepatitis autoinmune, la cual ingresó a una clínica privada para la realización de un liposucción más lipoinyección grasa; finalizando la cirugía presentó disminución progresiva de los niveles de saturación de oxígeno y de capnometría, marcando trazos de actividad eléctrica sin pulso, se le realizaron maniobras de RCP (reanimación cardiopulmonar), más la administración de enipinefrina, sin resultados. Fue trasladada al hospital donde nuevamente se le realizaron maniobras de RCP y posteriormente, a menos de una hora de haber ingresado, se corroboró la ausencia de actividad cardíaca mediante ultrasonido y se declaró a la paciente fallecida. El embolismo graso es conocido porser una entidad frecuente en las cirugías ortopédicas, sin embargo dado el aumento en la oferta y demanda de las cirugías plásticas, entre ellas la liposucción, se ha presentado con una mayor incidencia en los procedimientos estéticos con el pasar del tiempo, tomando mayor interés y entre los médicos que realizan dichos procedimientos.

Abstract:We report the case of a 30-year-old woman with cirrhosis due to autoimmune hepatitis, who entered a private clinic to perform lipoinjection and fat liposuction; At the end of surgery, progressive reduction of oxygen saturation levels and capnometry, marking strokes of electrical activity without pulse, CPR maneuvers, and enipinefrin administration were performed, with no results. She was transferred to the hospital where CPR maneuvers were performed again, and later, less than one hour after her admission, the absence of heart disease was corroborated by ultrasound and the patient was declared deceased. Fat embolism is known to be a frequent entity in orthopedic surgeries; however, given the increase in the supply and demand of plastic surgeries, among them liposuction, it has been presented with a greater incidence in aesthetic procedures with the passing of the time, taking greater interest andamong the doctors who perform such procedures.

Fat embolism syndrome in femoral shaft fractures: does the initial treatment make a difference? / Síndrome da embolia gordurosa na fratura diafisária de fêmur: o tratamento provisório faz diferença?

ABSTRACT Objective: To identify the risk factors correlated with the initial treatment performed. Methods: This is a retrospective study involving a total of 272 patients diagnosed with femoral shaft fractures. Of the patients, 14% were kept at rest until the surgical treatment, 52% underwent external fixation, 10% received immediate definitive treatment, and 23% remained in skeletal traction (23%) until definitive treatment., Results: There were six cases of fat embolism syndrome (FES), which showed that , polytrauma is the main risk factor for its development and that initial therapy was not important. Conclusion: Polytrauma patients have a greater chance of developing FES and there was no influence from the initial treatment.

RESUMO Objetivo: Identificar os fatores de risco e correlacioná-los com o tratamento inicial. Métodos: Estudo retrospectivo que envolveu 272 pacientes com diagnóstico de fratura diafisária de fêmur; 14% permaneceram em repouso até o tratamento cirúrgico, 52% foram submetidos a fixação externa, 10% fizeram o tratamento definitivo imediato e 23% permaneceram com tração esquelética até o tratamento definitivo. Resultados: Foram seis casos de síndrome da embolia gordurosa (SEG), nos quais se evidenciou que o politrauma é o principal fator de risco para seu desenvolvimento e que o tratamento inicial instituído não o influenciou. Conclusão: Pacientes politraumatizados apresentaram uma maior chance de desenvolver SEG e não houve influência do tratamento inicial instituído.

Síndrome de embolia grasa con predominio de síntomas neurológicos / Fat embolism syndrome with predominant neurological symptoms / Síndrome de embolia gordurosa com predomínio de sintomas neurológicos

Introducción. La embolia grasa es la obstrucción de los vasos sanguíneos de pequeño calibre por lípidos producidos durante la degradación tisular. Se presenta en individuos con fracturas de huesos largos, y es asintomático en más del 90 % de los casos. El síndrome de embolia grasa corresponde a un proceso grave poco frecuente en la práctica clínica, caracterizado por la aparición de petequias, dificultad respiratoria y alteraciones neurológicas. Reporte de caso. Se trata de una mujer adulta joven con trauma cerrado de tórax y fracturas múltiples de huesos largos de las extremidades superiores e inferiores por politraumatismo de alta energía, que fue sometida a reducción bajo anestesia de las fracturas. A las 48 horas, comenzó a presentar dificultad respiratoria, exantema petequial de predominio en la pared anterior del tórax y deterioro neurológico con convulsiones tónico-clónicas focales y bilaterales, que cedieron con un medicamento anticonvulsivo intravenoso. Se le diagnosticó síndrome de embolia grasa debido al antecedente de trauma y a las lesiones evidenciadas en la resonancia magnética. Se le brindó soporte respiratorio y terapia anticoagulante, con lo cual el cuadro clínico mejoró. Discusión. El tejido graso ingresa a la circulación cuando la presión en el lecho del drenaje venoso es superada por la presión en la médula ósea. Los ácidos grasos libres tóxicos causan edema vasogénico y citotóxico, así como hemorragia por destrucción celular. Conclusión. Es importante considerar la presencia de esta complicación en pacientes con múltiples fracturas y brindar un tratamiento oportuno con la intención de disminuir las secuelas asociadas con esta condición

Introduction: Fatty embolism is the obstruction of small blood vessels by lipid product of tissue degradation. It occurs in individuals with long bone fractures, being asymptomatic in more than 90% of cases. The fat embolism syndrome corresponds to a severe and rare process in clinical practice, characterized by the appearance of petechiae, respiratory stress and neurological disorders. Case report: Young adult with high energy-polytrauma and closed chest trauma with multiple fractures of long bones of the upper and lower extremities who was taken to operating theater for redu-cing them under anesthesia. Forty-eight hours after, she began to present with respiratory distress, petechial rash predominantly in the anterior thorax and neurological deterioration with focal seizure activity to bilateral tonic-clonic, which yielded with intravenous anticonvulsant. A fat embolism syndrome was diagnosed due to the history of trauma and the lesions evidenced in the magnetic resonance. She was given respiratory support and anticoagulant therapy, with which the clinical picture improved. Discussion: The fatty tissue enters the circulation when the venous drainage bed pressure is overcome by the pressure inside the bone marrow. The toxic free fatty acids cause vasogenic and cytotoxic edema, as well as hemorrhage by cell destruction. Conclusion: It is important to consider the presence of this complication in patients with multiple fractures and to offer timely treatment with the intention of reducing the sequelae associated with this condition.

Introdução. Embolia gordurosa é a obstrução dos vasos sanguíneos de diâmetro reduzido pelos lipídios produzidos durante a degradação tecidual. Ocorre em indivíduos com fraturas de ossos longos e é assintomática em mais de 90% dos casos. A síndrome da embolia gordurosa corresponde a um processo grave, pouco frequente na prática clínica, caracterizado pelo aparecimento de petéquias, dificuldade respiratória e alterações neurológicas. Relato de caso. Trata-se de uma mulher adulta jovem, com trauma de tórax fechado e múltiplas fraturas de ossos longos dos membros superiores e inferiores por politraumatismos de alta energia, que foi submetida a redução sob anestesia. Às 48 horas, ela começou a ter dificuldade em respirar, exantema petequial predominantemente sobre a parede torácica anterior e dano neurológico com convulsões tónico-clónicas e bilateral focal, que cedeu com uma medicação anticonvulsivante intra-venosa. Ela foi diagnosticada com síndrome de embolia gordurosa devido a uma história de trauma e às lesões evidenciadas na ressonância magnética. Ela recebeu suporte respiratório e terapia anticoa-gulante, com o qual o quadro clínico melhorou. Discussão. O tecido adiposo entra na circulação quando a pressão no leito da drenagem venosa é superada pela pressão na medula óssea. Os ácidos graxos livres tóxicos causam edema vasogênico e citotóxico, além de hemorragia por destruição celular. Conclusão. É importante considerar a presença dessa complicação em pacientes com múltiplas fraturas e fornecer tratamento oportuno com a intenção de reduzir as sequelas associadas a essa condição

A Case Of Two Common Culprits Causing Pulmonary Embolism

Pulmonary embolism is the obstruction of the pulmonary artery or its branches, commonly by thrombus or fat. We report an unusual case of double pathology - both pulmonary thromboembolism and fat embolism syndrome in a patient with bilateral femur and bilateral tibia fractures. This highlights the importance of a high index of suspicion of these conditions while managing patients with multiple long bone fractures. Morbidity and mortality can be significantly reduced with prompt and appropriate prevention strategies.

Surgical Outcomes of Biologic Fixation for Subtrochanteric Fracture Using Locking Compression Plates / 대한고관절학회지

PURPOSE: This study aimed to evaluate the surgical outcomes of biologic plating using locking compression plate-distal femur (LCP-DF) in patients with subtrochanteric fracture of the femur. MATERIALS AND METHODS: Between January 2010 and December 2013, 28 consecutive patients with subtrochanteric fractures of the femur, treated with biologic fixation using LCP-DF, were enrolled. Preoperative values, including patient age, sex, body mass index, fracture type, type of lung injury, and surgical timing from injury to surgery, were retrospectively evaluated. Radiologic assessments included time to union, coronal alignment, rotational alignment, and complications such as implant breakage and screw breakage. Adverse events, including postoperative fat embolism and adult respiratory distress syndrome, infection during the follow-up period, and walking ability at the last follow-up visit, were assessed. RESULTS: Union was achieved in 27 patients (96.4%) after a mean duration of 5.4 months (range, 3-14 months). No patients developed fat embolism or adult respiratory distress syndrome during the hospitalization period of this study. CONCLUSION: Biologic fixation using locking compression plates may represent a safe surgical option which can be utilized in patients with subtrochanteric fracture regardless of injury severity, surgical timing, fracture type, and presence of lung injury.
