ABSTRACT

ABSTRACT Direct carotid-cavernous fistula is a high-flow communication between the internal carotid artery and the cavernous sinus that requires early transarterial embolization for its resolution. We report a case of a patient with a direct carotid-cavernous fistula who subsequently developed a central retinal vein thrombosis due to a delay in treatment related to the health collapse experienced in the first months of the Covid-19 pandemic in Spain.


RESUMO A fístula carótido-cavernosa direta é uma comunicação de alto fluxo entre a artéria carótida interna e o seio cavernoso que requer embolização trans-arterial precoce para sua resolução. É relatado aqui o caso de um paciente com fístula carótido-cavernosa direta que posteriormente desenvolveu uma trombose da veia central da retina devido a um atraso no tratamento relacionado ao colapso de saúde experimentado nos primeiros meses da pandemia de Covid-19 na Espanha.

ABSTRACT

ABSTRACT Endomyocardial fibrosis is a neglected tropical disease that leads to restrictive cardiomyopathy. Its etiopathogenis is unclear and involves the progression of 3 stages of the disease. Compared with echocardiography, cardiac magnetic resonance imaging shows better apical visualization of obliteration and thrombus and provides an early diagnosis. However, there is no specific drug therapy, although surgery can increase survival. Therefore, surgical resection of the fibrous and thickened endocardium is recommended for symptomatic patients. The risk of mortality increases as the ratio of endocardial fibrous tissue per body surface rises. The aim of this manuscript is to describe the surgical management of the right-sided endomyocardial fibrosis mimicking tumor with recurrent pulmonary embolism.

ABSTRACT

Budd-Chiari syndrome [BCS] is a rare, potentially life-threatening condition characterized by the triad of abdominal pain, ascites, and hepatomegaly (with or without jaundice). There will be an underlying disorder in most cases. The diagnosis, as well as management of the case, requires a multidisciplinary approach. The treatment should aim at reducing the presenting symptoms as well as removing the underlying pathology. Here we explain a case report of a 21-year-old male patient in the subacute stage of BCS with its complications and considered as a candidate for liver transplantation. His liver enzymes, PT/INR, D- dimer, and homocysteine values were above normal levels. The arterial oxygen saturation level was subnormal, and he was on supportive oxygen supplement. Inferior venacava [IVC] Doppler revealed a non-obstructive intrahepatic thrombus. The patient was treated with Homoeopathic medicine Arsenicum album and Arnica montana, given as an adjuvant to conventional treatment.

ABSTRACT

Abstract Vein thrombosis of unusual sites such as the splanchnic region continues to be not only a diagnostic but also a therapeutic challenge for the clinician due to its manifestation and associated pathologies. Latent JAK2 (Janus kinase 2) positive myeloproliferative neoplasm associated with sticky platelet syndrome is unusual. We present a clinical case of a 38-year-old female patient who presented with sudden onset abdominal pain of a possible vascular origin. Splanchnic thrombosis was diagnosed in latent myeloproliferative neoplasm by identifying the JAK2V617F mutation and sticky platelet syndrome via platelet aggregometry. Off-label anticoagulation with rivaroxaban 20 mg/day was administered. During her outpatient follow-up, she did not suffer any new thrombotic episodes.


Resumen La trombosis venosa de sitios inusuales como la esplácnica continúa siendo un reto no solo diagnóstico sino también terapéutico para el clínico debido a su forma de presentación y las patologías asociadas. La neoplasia mieloproliferativa latente JAK2 (cinasa de Janus 2) positiva asociada con síndrome de plaqueta pegajosa es inusual. Se presenta un caso clínico de una paciente de 38 años de edad que debutó con dolor abdominal de inicio súbito que sugirió un posible origen vascular. Se diagnosticó trombosis esplácnica en relación con neoplasia mieloproliferativa latente por la identificación de la mutación de la JAK2V617F y síndrome de plaqueta pegajosa mediante agregometría plaquetaria. Se administró de manera off-label anticoagulación con rivaroxabán 20 mg/día. Durante su seguimiento ambulatorio no ha presentado nuevos episodios trombóticos.

ABSTRACT

Resumen A pesar de la tromboprofilaxis estándar, el diagnóstico de trombosis es común en pacientes críticos con COVID-19. El objetivo del presente estudio fue evaluar la incidencia de trombosis venosa profunda (TVP) en pacientes con neumonía grave por COVID-19 con requerimientos de asistencia respiratoria mecánica, bajo tromboprofilaxis química con dosis intermedia (1 mg/kg/día) de heparina de bajo peso molecular (enoxaparina). Se trató de un estudio unicéntrico, descriptivo y de corte transversal de datos recopilados en forma prospectiva. Se realizó búsqueda activa y sistemática de TVP en miembros inferiores (o en confluente yúgulosubclavio en su defecto) mediante doppler venoso cada 7 días. Se continuó con la evaluación por doppler semanal hasta la finalización de la ventilación mecánica, el cum plimiento de los 28 días de internación en unidad de cuidados intensivos, el fallecimiento o la suspensión de la tromboprofilaxis con enoxaparina por cualquier causa. Se incluyeron 46 pacientes. Se realizó diagnóstico de TVP en 5 (3 en miembros inferiores y 2 en con fluente yúgulosubclavio). Tres diagnósticos de TVP fueron asociados a la presencia de catéter venoso central (2 en miembros inferiores y 1 en el confluente yúgulosubclavio), dos fallecieron durante el seguimiento por causas vinculadas al síndrome de distrés respiratorio agudo (SDRA) pero no por eventos trombóticos o de sangrado mayor. En todos los casos, los eventos trombóticos fueron asintomáticos. En nuestra serie de pacientes con SDRA moderado/grave secundario a neumonía por COVID-19, la incidencia de TVP fue del 10.9% en aquellos bajo tromboprofilaxis con dosis intermedia (1 mg/kg/día) de enoxaparina.


Abstract Despite standard thrombo prophylaxis, venous thrombosis is common in critically ill patients with COVID-19. The objective of this study was to evaluate deep venous thrombosis (DVT) incidence in patients with severe COVID-19 pneumonia with mechanical ventilation requirements under intermediate dose of chemical thromboprophylaxis (1 mg/kg/day of enoxaparin). This was a single-center, descriptive, cross-sectional study of prospectively collected data. An active and systematic protocol with venous doppler was carried out for DVT diagnosis in lower limbs (or in jugulo-subclavian venous confluence) every 7 days. Weekly doppler evaluation was continued until the end of mechanical ventilation, up to 28 days of intensive care unit admission, until death or until the thromboprophylaxis suspension for any cause. Forty-six patients were included. DVT was diagnosed in 5 (3 in lower limbs and 2 in jugulo-subclavian conflu ent). In 3 cases, DVT was catheter-related (2 in lower limbs and 1 in jugulo-subclavian confluent), 2 died during follow-up due to acute respiratory distress syndrome (ARDS) complications without thrombotic events or major bleeding. All thrombotic events were asymptomatic. In our series of patients with moderate/severe COVID-19 ARDS, DVT incidence was 10.9% under thromboprophylaxis with intermediate dose (1 mg/kg/ day) of enoxaparin.

ABSTRACT

Resumen La enfermedad tromboembólica venosa es la causa prevenible más frecuente de muerte hospitalaria. A pesar de contar con evidencia y recomendaciones sobre la utilidad de la tromboprofilaxis, la adherencia por parte de los médicos a las mismas es muy variable, y frecuentemente subóptima. El objetivo de este estudio fue evaluar un programa institucional con estrategias multifacéticas dirigido a médicos, sobre tromboprofilaxis en internación y estimar el cambio en la adecuación de la tromboprofilaxis antes y después de la intervención. La intervención se mantuvo durante 6 años, fue múltiple, utilizando acciones pasivas como car telería, y activas, como educación médica continua, confección y adopción de una guía institucional de práctica clínica y un sistema de soporte informático para la decisión clínica. La adecuación basal de la tromboprofilaxis mejoró de 59% a 82% después de la intervención y se mantuvo en el tiempo. La mejora en la adecuación se asoció a una reducción de los sangrados mayores, en particular en pacientes intervenidos quirúrgicamente.


Abstract Venous thromboembolic disease is the most common preventable cause of hospital death. Despite the existence of evidence of the usefulness of thromboprophylaxis and recommendations, adherence by physicians to them is highly variable, and frequently suboptimal. The objective was to evaluate the change in the adequacy of thromboprophylaxis before and after an intervention on thromboprophylaxis with multifaceted strategies for physicians. The intervention was a 6 years institutional program with multiple strategies: passive actions such as posters and active actions as continuous medical education, adaptation of an institutional clinical practice guide and a computerized clinical decision support system. The baseline adequacy of thromboprophylaxis improved from 59% to 82% and was maintained over time. The improvement in fitness was associated with a reduction in major bleeding, particularly in patients undergoing surgery.

ABSTRACT

ABSTRACT Cerebral venous sinus thrombosis (CVT) consists of partial or complete occlusion of a sinus or a cerebral vein. CVT represents 0.5-1% of all strokes and is more frequent in young women. This review discusses particular aspects of CVT diagnosis and management: decompressive craniectomy (DC), anticoagulation with direct oral anticoagulants (DOACs), CVT after coronavirus-disease 19 (COVID-19) and Vaccine-Induced Immune Thrombotic Thrombocytopenia (VITT).


RESUMO A trombose venosa cerebral (TVC) consiste na oclusão parcial ou completa de um seio ou de uma veia cerebral. A TVC representa 0,5-1% das doenças cerebrovasculares e é mais frequente em mulheres jovens. Esta revisão discute aspectos específicos do diagnóstico e do manejo da TVC: craniectomia descompressiva (DC), anticoagulação com anticoagulantes orais diretos (DOACs), TVC após infecção por coronavírus (COVID-19) e Trombocitopenia Trombótica Imune Induzida por Vacina (VITT).

ABSTRACT

ABSTRACT Introduction: Left ventricular assist devices are an established therapy for end-stage heart failure. Follow-up of these patients showed complications, such as thrombosis. Our objective was to evaluate the contribution of echocardiography — in association with HeartWare HVAD online logfiles reviews and lactate dehydrogenase titration — for diagnosis and treatment of thrombosis. Methods: Seventeen episodes of thrombosis were diagnosed in 8/20 patients with HVAD. Diagnosis was made by trans-thoracic echocardiographic blood flow velocities, logfiles review of power consumption and pump flows, and titration of lactate dehydrogenase. Data were collected at baseline routine control (Group A), during thrombosis (Group B), after thrombolysis (Group C). Results: Thrombolysis was successful in all cases; one patient died of cerebral haemorrhage. Echocardiographic maximal blood flow velocity near the inflow cannula was 598±42 cm/sec (Group B), 379.41±21 cm/sec (Group C), and 378.24±28 cm/sec (Group A) (P<0.00001). In eight (47%) cases, thrombi were visualized in the left ventricle by three-dimensional modality. Logfiles recordings of blood flows were 9.52±0.9 L/min (Group B), 4.02±0.4 L/min (Group C), and 4.04±0.4 L/min (Group A) (P<00001). Power consumption was 5.01±0.7 W (Group B), 3.45±0.2 W (Group C), and 3.46±0.2 W (Group A) (P<0.00001). Lactate dehydrogenase was 756±54 IU (Group B), 234±22 IU (Group A), and 257±36 IU (Group C) (P<0.00001). Conclusions: Echocardiography of increased maximal velocity near the inflow cannula is a sign of HVAD obstruction. Logfile reviews provide a clear picture of HVAD obstruction. Combination of echocardiographic data and review of logfiles detects signs of left ventricular assist devices thrombosis leading to a successful treatment.

ABSTRACT

RESUMEN Se presenta el caso de un paciente masculino de 22 años con trombosis venosa profunda de vena cava inferior, iliacas y femorales y que presenta como factores de riesgo una agenesia de la porción suprarrenal de la vena cava inferior y lupus eritematoso sistémico. Además, se evidenció la presencia de situs inversus total, condición que se asocia a malformaciones venosas presentes en el caso. Como tratamiento se utilizó anticoagulación con heparina de bajo peso molecular y posteriormente anticoagulante oral. A pesar el extenso territorio de la trombosis se descartó la necesidad de instalar filtro en la vena cava inferior por la ausencia de la misma en la aurícula derecha. Se intentó sin éxito la repermeabilización con trombolítico.


ABSTRACT We present the case of a 22-year-old male patient with deep vein thrombosis of the inferior vena cava, iliac and femoral veins, who presents as risk factors an agenesis of the suprarenal portion of the inferior vena cava and systemic lupus erythematosus. In addition, the presence of total situs inversus was evidenced, a condition that is associated with venous malformations present in the case. As treatment, anticoagulation was used with low molecular weight heparin and subsequently oral anticoagulant. Despite the extensive territory of the thrombosis, the need to install a filter in the inferior vena cava was ruled out due to its absence in the right atrium. Repermeabilization with thrombolytic therapy was attempted without success.

ABSTRACT

Abstract Identified in China in December 2019 as a new class of viral pneumonia of unknown origin, the new Coronavirus has already passed the milestone of 100 million people infected worldwide. The clinical course of this infection is characterized by fever, cough, upper airway congestion and complications related to Acute Respiratory Distress Syndrome. In addition, the virus can have repercussions that go beyond the impairment of the respiratory system, affecting other systems. Therefore, the aim of this study is to describe the correlation between Covid-19 and thromboembolic and cardiovascular events. It is a Systematic Review that was submitted to searches in the PubMed, SciELO, Lilacs and Bireme databases. Six observational studies comprising 1539 patients were included in this review. The quality of the articles was evaluated according to the New Castle-Ottawa scale. After extracting data from the studies, it was observed that hospitalized patients diagnosed with Covid-19 infection are more likely to develop Venous Thromboembolism (VTE) and Pulmonary Embolism (PE), as well as cardiovascular events, although the latter are less frequent. These patients also have alterations in the pulmonary parenchyma, being proportional to the severity of the case, as well as the prevalence of d-dimer, the rate of thrombosis in the pulmonary artery, the need for intensive care and the mortality rate. Thus, the severe form of infection by Covid-19 manifests consequences that do not only involve the respiratory system, compromising the blood clotting of affected patients, leading to a higher incidence of thromboembolic and cardiovascular events. (AU)


Resumo Identificado na China em dezembro de 2019 como uma nova classe de pneumonia viral, de origem desconhecida, o novo Coronavírus já ultrapassou o marco de 100 milhões de pessoas infectadas em todo o mundo. A evolução clínica desta infecção é caracterizada por febre, tosse, congestão das vias aéreas superiores e complicações relacionadas a um quadro de Síndrome do Desconforto Respiratório Agudo. Além disso, o vírus pode apresentar repercussões que vão além do comprometimento do sistema respiratório, afetando outros sistemas. Portanto, o objetivo deste estudo é descrever a correlação entre a Covid-19 e os eventos tromboembólicos e cardiovasculares. Trata-se de uma Revisão Sistemática que foi submetida a pesquisas nos bancos de dados PubMed, SciELO, Lilacs e Bireme. Foram incluídos 6 estudos observacionais envolvendo 1539 pacientes nesta revisão. A qualidade dos artigos foi avaliada de acordo com a escala New Castle-Ottawa. Após a extração de dados dos estudos, observou-se que pacientes hospitalizados e diagnosticados com infecção por Covid-19 apresentam maior predisposição a desenvolver Tromboembolismo Venoso (TEV) e Embolia Pulmonar (EP), bem como eventos cardiovasculares, apesar destes últimos serem menos frequentes. Estes pacientes também cursam com alterações do parênquima pulmonar sendo proporcionais a gravidade do caso, assim como a prevalência de d-dímero, a taxa de trombose na artéria pulmonar, a necessidade de cuidados intensivos e a taxa de mortalidade. Assim, a forma grave da infecção por Covid-19 manifesta consequências que não envolvem apenas o sistema respiratório, comprometendo a coagulação sanguínea dos pacientes acometidos levando a maior incidência de eventos tromboembólicos e cardiovasculares.

ABSTRACT

RESUMEN INTRODUCCION: La trombosis del seno venoso se considera una de las causas más infrecuentes de enfermedad cerebrovascular (ECV), prevalente en la edad joven. Suele tener un inicio insidioso, lo cual dificulta su diagnóstico y el inicio oportuno del tratamiento, y se encuentra asociada con múltiples factores de riesgo, incluyendo estados de hipercoagulabilidad, como en aquellos pacientes que cursan con infección por SARS-CoV-2. REPORTE DE CASO: Se presentan dos casos clínicos de pacientes con alteraciones neurológicas, diplopia y estatus epiléptico, en quienes se documentó por medio de la sintomatologia y de estudios imagenológicos, trombosis venosas extensas de localización infrecuente, se descartaron las principales etiologías asociadas, y el único nexo asociado fue la infección por SARS-CoV-2. Ambos pacientes recibieron tratamiento con anticoagulación parenteral, al que respondieron de forma exitosa, por lo cual se logró el alta posteriormente con anticoagulación oral. DISCUSIÓN: Es imprescindible el conocimiento de esta enfermedad, asociada con una alta sospecha diagnóstica, dadas sus manifestaciones clínicas variadas y su asociación cada vez más frecuente con infección por covid-19.


ABSTRACT INTRODUCTION: Venous sinus thrombosis is considered one of the most infrequent causes of cerebrovascular disease (CVD), prevalent in young people. It usually has an insidious onset which difficult its diagnosis and timely initiation of treatment and is associated with multiple risk factors including hypercoagulable states, as in those patients with SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) infection. CASE REPORT: The following are 2 clinical cases of patients with neurological alterations, diplopia, and status epilepticus, in whom extensive venous thrombosis of infrequent location was documented through symptomatology and imaging studies, ruling out the main associated etiologies, with the only associated nexus: SARS-CoV-2 infection. Both patients received treatment with parenteral anticoagulation, responding successfully and were subsequently discharged with oral anticoagulation. DISCUSSION: It is essential to be aware of this disease associated with a high diagnostic suspicion given its varied clinical manifestations and its increasingly frequent association with COVID-19 infection.

ABSTRACT

ABSTRACT BACKGROUND: The intensity of the thromboprophylaxis needed as a potential factor for preventing inpatient mortality due to coronavirus disease-19 (COVID-19) remains unclear. OBJECTIVE: To explore the association between anticoagulation intensity and COVID-19 survival. DESIGN AND SETTING: Retrospective observational study in a tertiary-level hospital in Spain. METHODS: Low-molecular-weight heparin (LMWH) status was ascertained based on prescription at admission. To control for immortal time bias, anticoagulant use was analyzed as a time-dependent variable. RESULTS: 690 patients were included (median age, 72 years). LMWH was administered to 615 patients, starting from hospital admission (89.1%). 410 (66.7%) received prophylactic-dose LMWH; 120 (19.5%), therapeutic-dose LMWH; and another 85 (13.8%) who presented respiratory failure, high D-dimer levels (> 3 mg/l) and non-worsening of inflammation markers received prophylaxis of intermediate-dose LMWH. The overall inpatient-mortality rate was 38.5%. The anticoagulant nonuser group presented higher mortality risk than each of the following groups: any LMWH users (HR 2.1; 95% CI: 1.40-3.15); the prophylactic-dose heparin group (HR 2.39; 95% CI, 1.57-3.64); and the users of heparin dose according to biomarkers (HR 6.52; 95% CI, 2.95-14.41). 3.4% of the patients experienced major hemorrhage. 2.8% of the patients developed an episode of thromboembolism. CONCLUSIONS: This observational study showed that LMWH administered at the time of admission was associated with lower mortality among unselected adult COVID-19 inpatients. The magnitude of the benefit may have been greatest for the intermediate-dose subgroup. Randomized controlled trials to assess the benefit of heparin within different therapeutic regimes for COVID-19 patients are required.

ABSTRACT

Resumen La enfermedad producida por el COVID-19 ha generado un problema sanitario mundial sin precedentes. La infección se considera como un potencial factor de riesgo para desarrollar complica ciones tromboembólicas, principalmente, embolia pulmonar, infarto de miocardio y accidente cerebrovascular. El objetivo de este trabajo fue describirlas en los pacientes internados por COVID-19 y su evolución. Se realizó un estudio observacional unicéntrico prospectivo que comparó las características basales, factores de riesgo, tasa de eventos tromboembólicos, estadía y mortalidad hospitalaria entre los pacientes que se internaron en cuidados intensivos o sala general. Se incluyeron 1125 pacientes, 124 internados en unidad cuidados intensivos y 1001 internados en sala general de internación. La edad promedio fue de 46 ± 18 años, con 585 (52%) de sexo femenino. La tasa global de eventos tromboembólicos fue de 4.4%, siendo significativamente mayor en los pacientes de UCI (29% vs. 1.4%; p < 0.001) a pesar del elevado uso de heparina profiláctica (91.1% vs. 84.9%; p < 0.1), comparados con los internados en SGI. Los factores predictores independientes de desarrollo de eventos tromboembólicos fueron: la edad, el dímero D y la creatinina. La mortalidad global fue 4.3%, siendo significativamente mayor en los pacientes de cuidados intensivos sobre los de sala general de internación (29% vs. 1.3%; p < 0.001). Los pacientes que requieren internación por COVID-19 presentan elevada tasa de eventos tromboembólicos a pesar del uso de tromboprofilaxis con heparina, generando un impacto pronóstico negativo sobre la supervivencia de aquellos internados en cuidados intensivos.


Abstract Coronavirus disease-19 has emerged as a devastating global public health crisis. An increased frequency of arterial and venous thrombosis was observed in COVID-19 infection. The objective of this study was to describe the thromboembolic complications of patients hospitalized for COVID-19 and their evolution. A prospective single-center study was conducted that compared the characteristics, risk factors, thromboembolic event rate, hospital stay and mortal ity among patients admitted to intensive care or general ward. The mean age of population was 46 ± 18 years, and 52% were female. The global rate of thromboembolic events was 4.4%, significantly higher in intensive unit patients (29% vs 1.4%; p < 0.001) despite the high use of prophylactic heparin (91.1% vs. 84.9%; p < 0.1). The independent predictive factors for the development of thromboembolic events were: age, D-dimer and creatinine. Of the patients admitted to intensive care, 45.1% required mechanical ventilation. Overall mortality was 4.3%, significantly higher in intensive care patients than in the general hospital ward (29% vs. 1.3%; p < 0.0001). Pa tients requiring hospitalization due to infection secondary to COVID-19 have a high rate of thromboembolic events despite the use of thromboprophylaxis with heparin, generating a negative prognostic impact on the survival of patients admitted to intensive care.

ABSTRACT

Abstract Cerebral venous thrombosis (CVT) is an uncommon condition that is potentially reversible if properly diagnosed and promptly treated. Although CVT can occur at any age, it most commonly affects neonates and young adults. Clinical diagnosis is difficult because the clinical manifestations of CVT are nonspecific, including headache, seizures, decreased level of consciousness, and focal neurologic deficits. Therefore, imaging is crucial for the diagnosis. Radiologists should be able to identify the findings of CVT and to recognize potential imaging pitfalls that may lead to misdiagnosis. Thus, the appropriate treatment (anticoagulation therapy) can be started early, thereby avoiding complications and unfavorable outcomes.


RESUMO A trombose venosa cerebral (TVC) é uma condição incomum que é potencialmente reversível se diagnosticada corretamente e prontamente tratada. Embora a TVC possa ocorrer em qualquer idade, ela afeta mais comumente neonatos e adultos jovens. O diagnóstico clínico é difícil porque as manifestações clínicas da TVC são inespecíficas, como cefaleia, convulsões, diminuição do nível de consciência e déficits neurológicos focais. Nesse contexto, a imagem é crucial para o diagnóstico e os radiologistas devem ser capazes de identificar os achados de TVC e reconhecer potenciais armadilhas de imagem que podem levar a diagnósticos incorretos. Portanto, o tratamento adequado (terapia anticoagulante) deve ser iniciado precocemente para evitar complicações e desfechos desfavoráveis.

ABSTRACT

@#BACKGROUND: To investigate the clinical effectiveness of a pneumatic compression device (PCD) combined with low-molecular-weight heparin (LMWH) for the prevention and treatment of deep vein thrombosis (DVT) in trauma patients. METHODS: This study retrospectively analyzed 286 patients with mild craniocerebral injury and clavicular fractures admitted to our department from January 2016 to February 2020. Patients treated with only LMWH served as the control group, and patients treated with a PCD combined with LMWH as the observation group. The incidence of DVT, postoperative changes in the visual analogue scale (VAS) score, and coagulation function were observed and compared between the two groups. Excluding the influence of other single factors, binary logistic regression analysis was used to evaluate the use of a PCD in the patient's postoperative coagulation function. RESULTS: After excluding 34 patients who did not meet the inclusion criteria, 252 patients were were included. The incidence of DVT in the observation group was significantly lower than that in the control group (5.6% vs. 15.1%, χ2=4.605, P<0.05). The postoperative VAS scores of the two groups were lower than those before surgery (P<0.05). The coagulation function of the observation group was significantly higher than that of the control group, with a better combined anticoagulant effect (P<0.05). There were no significant differences between the two groups in preoperative or postoperative Glasgow Coma Scale scores, intraoperative blood loss, postoperative infection rate, or length of hospital stay (P>0.05). According to logistic regression analysis, the postoperative risk of DVT in patients who received LMWH alone was 1.764 times that of patients who received LMWH+PCD (P<0.05). The area under the receiver operating characteristic (AUROC) curve of partial thromboplastin time (APTT) and platelet (PLT) were greater than 0.5, indicating that they were the influence indicators of adding PCD to prevent DVT. Excluding the influence of other variables, LMWH+PCD effectively improved the coagulation function of patients. CONCLUSIONS: Compared with LMWH alone, LMWH+PCD could improve blood rheology and coagulation function in patients with traumatic brain injury and clavicular fracture, reduce the incidence of DVT, shorten the length of hospital stay, and improve the clinical effectiveness of treatment.

ABSTRACT

Objective To investigate the clinical application value of contrast-enhanced ultrasound (CEUS) in hepatic artery thrombosis (HAT) after pediatric liver transplantation. Methods Clinical data of 126 pediatric recipients undergoing liver transplantation were retrospectively analyzed. The incidence of HAT after pediatric liver transplantation was summarized. Color Doppler ultrasound and CEUS manifestations of HAT were compared. Results According to color Doppler ultrasound, 17 cases were highly suspected with HAT. Nine cases were highly suspected with HAT by CEUS, who were subsequently confirmed by CT angiography (CTA) or surgery. CEUS manifestations of HAT showed that hepatic artery was not seen surrounding the portal vein during the arterial phase or even portal venous phase. Hepatocyte necrosis occurred in 4 patients with HAT, and no perfusion of intrahepatic contrast agent was observed on CEUS. Conclusions CEUS yields high clinical application value in the diagnosis of HAT after pediatric liver transplantation. It has significant advantages compared with traditional CTA, which could be widely applied in clinical practice.
