Síndrome de Balint y trombosis de senos venosos cerebrales: reporte de caso / Balint syndrome and cerebral venous sinus thrombosis: Case report

Introducción: El síndrome de Balint es un trastorno neurológico infrecuente, de etiología diversa, cuya presentación incluye la triada clásica de: simultagnosia, ataxia óptica y apraxia oculomotora, síntomas secundarios asociados a lesiones parieto-occipitales, con pronóstico variable según la etiología que se encuentre. A continuación, se reporta un caso secundario a una trombosis de senos venosos. Presentación del caso: Mujer de 66 años que ingresa a urgencias por cefalea aguda asociada a síntomas neurológicos progresivos con compromiso visual. Presentó tensión arterial elevada, simultagnosia, ataxia óptica y apraxia oculomotora. Los estudios imagenológicos reportaron hemorragia subaracnoidea por trombosis de seno sigmoideo izquierdo, por lo que se inició anticoagulación, antihipertensivo, con adecuada evolución del cuadro clínico. Discusión: A pesar de que el síndrome de Balint es un trastorno poco común, de etiología diversa, con escasos reportes a escala global, el caso comentado concordó con las características descritas en la literatura. El abordaje de la paciente en su atención inicial permitió la sospecha diagnóstica oportuna y la indicación de ayudas diagnósticas imagenológicas pertinentes. Tales ayudas soportaron un manejo temprano y la adecuada evolución y resolución del cuadro, en el contexto de la asociación del síndrome a una trombosis de senos venosos cerebrales (una etiología infrecuente). Conclusión: Mediante una historia clínica completa y minuciosa, junto a un adecuado examen neurológico, es posible hacer un acercamiento diagnóstico temprano que permita generar la sospecha del síndrome de Balint y la solicitud temprana de imágenes diagnósticas que orienten en el estudio de su etiología y manejo oportuno, con mejores desenlaces en el paciente.

Introduction: Balint Syndrome is a rare neurological disorder with multiple etiologies. The physical signs include a classic triad (simultagnosia, optic ataxia, and oculomotor apraxia). These symptoms are associated with parieto-occipital lesions, and the prognosis depends on the etiology. This article reports a case secondary to venous sinus thrombosis. Presentation of the case: A 66-year-old woman presented to the emergency room with acute headache associated with progressive neurological symptoms and visual impairment. She had high blood pressure, simultanagnosia, optic ataxia, and oculomotor apraxia. Imaging studies revealed subarachnoid hemorrhage due to thrombosis of the left sigmoid sinus, for which anticoagulation and antihypertensive therapy were started. The patient had a favorable clinical outcome. Discussion: Although Balint syndrome is a rare disorder of diverse etiology with few clinical cases reported globally, the case discussed here was consistent with the characteristics described in the literature. The patient's initial assessment allowed for timely diagnostic suspicion and appropriate imaging studies, which supported early management and the appropriate evolution and resolution of the condition, given the association of the syndrome with an uncommon cause as cerebral venous sinus thrombosis. Conclusion: A complete and thorough medical history, along with a proper neurological exam, can lead to an early diagnostic approach that raises suspicion of Balint's syndrome and prompts timely imaging studies to guide the investigation of its etiology and management, ultimately leading to better outcomes for the patient.

Deep Vein Thrombosis after a Supracondylar Fracture of the Humerus in a Child - A Rare Complication / Trombose venosa profunda após uma fratura supracondilar do úmero em uma criança - Uma complicação rara

Abstract Deep vein thrombosis in the upper extremities is uncommon, especially in the pediatric population and in the trauma setting. The diagnosis is challenging, due to its rarity, requiring a high degree of suspicion. We describe a rare case of humeral vein thrombosis after a displaced supracondylar fracture of the humerus in a 7-year-old girl. The risk factors for thromboembolism and sequelae are also discussed. The early detection and treatment are mandatory to prevent poor outcomes, such as fatal thromboembolism.

Resumo Trombose venosa profunda nas extremidades superiores é incomum, especialmente na população pediátrica e no ambiente do trauma. O diagnóstico é desafiador, devido a sua raridade, exigindo alto grau de suspeita. Descrevemos um caso raro de trombose venosa úmera após uma fratura supracondilar deslocada do úmero em uma menina de 7 anos. Os fatores de risco para tromboembolismo e sequelas também são discutidos. A detecção e o tratamento precoces são obrigatórios para evitar desfechos ruins, como tromboembolismo fatal.

Factores de riesgo de trombosis venosa profunda en el personal administrativo de una universidad ecuatoriana / Risk factors for deep vein thrombosis in the administrative staff of an ecuadorian university / Fatores de risco para trombose venosa profunda no pessoal administrativo de uma universidade equatoriana

Objetivo: describir los factores de riesgo de trombosis venosa profunda en el personal administrativo de una universidad ecuatoriana. Método: investigación cuantitativa, transversal y descriptiva, con una muestra censal de 71 trabajadores del área administrativa, en Ambato, Ecuador. Para la recolección de datos se utilizó el test que evalúa el manejo de la insuficiencia venosa crónica entre los niveles de atención a la salud. El análisis de datos se realizó mediante estadística descriptiva y el método multivariante de análisis de componentes principales para definir nuevos factores asociados. Resultados: los factores a la TVP son la bipedestación, consumo de tabaco y alcohol, sedestación, coagulación sanguínea, várices congénitas, enfermedades catastróficas, edema, algia, cirugía, anticonceptivos y uso de corticoesteroides. Conclusión: el riesgo de estos pacientes para desarrollar TVP está relacionado con el lugar de trabajo, la movilidad, signos y síntomas que la enfermedad puede causar. En el caso del personal administrativo los factores más asociados a la TVP se relacionan con la posición por largas jornadas de trabajo, no obstante factores de coagulación, patologías previas, signos notorios de la patología, consumo de alcohol y tabaco y el uso de corticoesteroides también aportan en un menor porcentaje al desarrollo.

Objective: to describe the risk factors for deep vein thrombosis in the administrative staff of an ecuadorian university. Method: quantitative, cross-sectional and descriptive research, with a census sample of 71 workers in the administrative area, in Ambato, Ecuador. For data collection, the test that evaluates the management of chronic venous insufficiency between levels of health care was used. Data analysis was performed using descriptive statistics and the multivariate method of principal component analysis to define new associated factors. Results: risk factors for DVT are standing, smoking and drinking alcohol, sitting, blood clotting, congenital varicose veins, catastrophic disease, edema, pain, surgery, contraceptives, and use of corticosteroids. Conclusion: the risk of these patients to develop DVT is related to the workplace, mobility, signs and symptoms that the disease can cause. In the case of administrative staff, the factors most associated with DVT are related to the position due to long working hours, however coagulation factors, previous pathologies, notorious signs of the pathology, alcohol and tobacco consumption, and the use of corticosteroids also contribute to development in a lower percentage.

Tromboembolismo pulmonar asociado a COVID-19 en paciente con síndrome de May-Thurner / COVID-19-associated Pulmonary Thromboembolism in a Patient with May-Thurner Syndrome

Introducción: El síndrome de May-Thurner es una enfermedad cuya prevalencia real es desconocida. Suele ser asintomática y las manifestaciones clínicas aparecen en el contexto de las complicaciones asociadas a la enfermedad. La aproximación diagnóstica se realiza por medio de imágenes, donde se identifican alteraciones patognomónicas que permiten descartar diagnósticos diferenciales. Se ha demostrado que la COVID-19 genera un estado protrombótico, que en contexto del síndrome de May-Thurner puede derivar en complicaciones tromboembólicas. Objetivo: Comparar la clínica y la posible relación de la enfermedad tromboembólica venosa en el curso de la COVID-19 en pacientes con SMT. Caso clínico: Mujer de 24 años, secretaria de profesión y residente en Bucaramanga. Presentó un cuadro clínico de 20 días de evolución que inició con rinorrea hialina, tos ocasional y mialgias; cinco días después manifestó fiebre no cuantificada y tos con expectoración hemoptoica. Conclusiones: Dentro de la fisiopatología de la infección por SARS-CoV-2 se desarrollan mecanismos procoagulantes, lo cual incrementa el riesgo de eventos trombóticos en pacientes con o sin factores de riesgo(AU)

Introduction: May-Thurner syndrome is a disease whose actual prevalence is unknown. It is usually asymptomatic and clinical manifestations appear in the context of complications associated with the disease. The diagnostic approach is performed by imaging, where pathognomonic alterations are identified to rule out differential diagnoses. It has been demonstrated that COVID-19 generates a prothrombotic state, which particularly in patients with May-Thurner syndrome would lead to thromboembolic complications. Objective: To compare the clinical and possible relationship of venous thromboembolic disease in the course of COVID-19 in patients with May-Thurner syndrome. Clinical case: 24-year-old woman, secretary by profession and resident in Bucaramanga, Colombia. She presented a clinical picture of 20 days of evolution that began with hyaline rhinorrhea, occasional cough and myalgias; five days later she manifested unquantified fever and cough with hemoptotic expectoration. Conclusions: Within the pathophysiology of SARS-CoV-2 infection, procoagulant mechanisms develop, which increases the risk of thrombotic events in patients with or without risk factors(AU)

Características de la trombosis venosa cerebral en pacientes de dos hospitales universitarios de Colombia en el período 2018-2020 / Characteristics of cerebral venous thrombosis in patients from two university hospitals in Colombia between 2018-2020

Introducción. La trombosis venosa cerebral es una causa infrecuente de enfermedad cerebrovascular que viene en aumento a nivel mundial. A pesar de ello, actualmente, en Colombia no se cuenta con estudios suficientes que nos permitan caracterizar epidemiológicamente la enfermedad en nuestra población para identificar los factores de riesgo y las complicaciones más frecuentes en nuestro medio. Objetivo. Describir las características clínicas, demográficas y radiológicas, y los factores de riesgo de una serie de pacientes con trombosis venosa cerebral de dos hospitales de Colombia. Materiales y métodos. Es un estudio descriptivo retrospectivo de pacientes hospitalizados, atendidos en el servicio de neurología de dos hospitales de Bogotá desde diciembre de 2018 hasta diciembre del 2020. Resultados. Se incluyeron 33 pacientes. Las frecuencias más altas correspondieron a mujeres en edad fértil, en puerperio (n=7; 33,3 %) y pacientes con patologías autoinmunes (n=10; 30,3 %). El síntoma inicial más común fue la cefalea (n=31; 93,9 %), seguido de focalización neurológica (n=9; 27,2%) y crisis epiléptica (n=8; 24,2 %). El 51 % (n=17) de los pacientes tuvo un examen físico normal. El infarto venoso cerebral se presentó en el 21,1 % (n=7), la hemorragia subaracnoidea en el 12,1 % (n=4) y el hematoma intraparenquimatoso en el 9 % (n=3) del total de pacientes. El 60,6 % (n=20) quedó con nivel independiente en la escala funcional de Barthel. Ningún paciente falleció. Conclusiones. Se encontraron características sociodemográficas, clínicas y radiológicas similares a lo reportado en la literatura mundial. Con respecto a las diferencias, se encontró en nuestro estudio compromiso de la circulación venosa cerebral profunda en un porcentaje ligeramente mayor a lo descrito, pero sin aumento de complicaciones, ni mortalidad.

Introduction. Cerebral venous thrombosis is an uncommon cause of cerebrovascular disease, which has been increasing worldwide. In Colombia, there are not enough recent studies that allow us to determine epidemiological characteristics of the disease in our population to identify more frequent risk factors and complications according to our living conditions. Objective. To describe clinical, demographic, and radiographic characteristics, and risk factors in a cohort of patients with cerebral venous thrombosis attended at two hospitals in Colombia. Materials and methods. Retrospective descriptive study with patients treated in the hospitalization neurology service of two hospitals in Bogotá, Colombia from December 2018 to December 2020. Results. Thirty-three patients were included. There was a higher incidence of cerebral venous thrombosis in women of childbearing age in the puerperium (n=7; 33.3%) and associated with autoimmune diseases (n=10; 30.3%). The most common initial symptom was headache (n=31; 93.9 %), followed by neurological focal signs (n=9; 27.2%) and seizures (n=8; 24.2%). Fifty-one percent (n=17) of the patients had a normal physical examination. Cerebral venous infarction occurred in 21.1 % (n=7), subarachnoid hemorrhage in 12.1 % (n=4), and intraparenchymal hematoma in 9 % (n=3) of all the patients. Sixty-point six percent (n=20) of the patients had a total independent Barthel functional scale. None of those died. Conclusions. We found similar sociodemographic, clinical, and radiography characteristics to those reported in the world literature. Regarding the differences, deep cerebral venous circulation was higher than that described in previous studies but without complications increase or mortality.

Current state of non-hematologic cancer-associated thrombosis at a tertiary care hospital in India

Abstract Introduction Cancer-associated thrombosis is a leading cause of morbidity and mortality in malignancy patients. Prophylactic anticoagulation is under-utilized and the cost of low-molecular-weight heparin (LMWH) and direct oral anticoagulants is a major barrier in developing countries. Material and methods A retrospective analysis was performed of all cancer-associated thrombosis patients attending the thrombosis clinic at a tertiary-level referral hospital based in North India between 2011 and 2015. Patient demographics and disease-related parameters were collected and analyzed. Results A total of 771 patients attended the thrombosis clinic during study period, of which 64 cases were malignancy-associated. Of these, 56% of the patients were female and 20% were bedridden. The median age was 48.5 years, adenocarcinoma (48%) being the most common histological subtype. Gynecological malignancies (30%) were the most common malignancies, followed by genitourinary (11%) malignancies. Most of the cases occurred during first year of diagnosis (51%), and only 14% occurred after 3 years. Most of the patients were on combined treatment. Almost 40% of the patients developed thrombosis within 30 days of surgical treatment. Lower limb thrombosis was the most commonly seen type (56%), while abdominal and pulmonary thrombosis were both seen in 5%. Patients were managed with LMWH and vitamin K antagonists (84.3%) and only 6.25% with LMWH alone. Direct oral anticoagulants were not commonly used during the study period. Discussion At the hospital studied, most of the cases occurred early in the disease course. Postoperative prophylaxis could have contributed towards reducing thrombosis in the peri-operative period. Early suspicion and prompt treatment can improve quality of life in such patients.

Plantar vein thrombosis: an uncommon cause of plantar foot pain / Trombose venosa plantar: uma causa incomum de dor em região plantar

INTRODUCTION: Plantar vein thrombosis is a rare condition that can lead to pain, edema, and walking difficulties. It presents a series of predisposing factors, such as recent surgeries, the use of oral contraceptives, and local trauma, among others. Imaging tests are essential for the right diagnosis, and ultrasonography is the modality of choice. As for treatment, there is no consensus in the literature. REPORT: Case of a 30-year-old patient who sought emergency medical care complaining of sudden severe pain in the plantar region of her right foot with walking difficulties. On physical examination, hyperalgesia was observed in the plantar region, irradiating to the calf, associated with swelling. Color Doppler imaging identified an acute thrombus in the medial plantar vein. Rivaroxaban was initially prescribed and replaced by acetylsalicylic acid after three months. The treatment was effective, and the patient was discharged after 11 months. CONCLUSION: Plantar vein thrombosis is a rare condition and has a wide range of differential diagnoses so physicians must maintain a high level of clinical suspicion. To improve diagnosis and treatment, it would be necessary to include plantar veins in the investigation protocols of patients suspected of having Deep Venous Thrombosis, besides additional clinical research for improving treatment.

INTRODUÇÃO: A trombose de veias plantares é uma condição rara que pode cursar com dor, edema e dificuldade na deambulação. Apresenta uma série de fatores predisponentes, como cirurgias recentes, uso de anticoncepcional oral, trauma local, entre outros. A realização de exame de imagem é essencial para o diagnóstico, sendo a ultrassonografia a modalidade de escolha. Quanto ao tratamento, não há consenso na literatura. RELATO: Relatamos o caso de uma paciente de 30 anos que procurou atendimento médico de urgência com queixa de dor de forte intensidade, súbita, em região plantar do pé direito com dificuldade de deambulação. Ao exame físico, observou-se hiperalgesia em região plantar com irradiação para panturrilha, associada a empastamento da mesma. O ecodoppler colorido identificou trombo agudo em veia plantar medial. Optou-se pela prescrição de rivaroxabana, a qual foi substituída por ácido acetilsalicílico após três meses. A paciente evoluiu bem e recebeu alta do tratamento após 11 meses. CONCLUSÃO: A trombose de veias plantares é rara e tem uma alta gama de diagnósticos diferenciais, de forma que o profissional médico deve manter um alto nível de suspeição clínica. Para aperfeiçoar seu diagnóstico e tratamento, seria necessária a inclusão das veias plantares aos protocolos de investigação de pacientes com suspeita de Trombose Venosa Profunda, e pesquisas clínicas que elucidassem os melhores métodos terapêuticos.

Aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban for lower extremity venous thrombosis after total knee arthroplasty: a randomized controlled trial / 中国针灸

OBJECTIVE@#To investigate the clinical effect of aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban for lower extremity venous thrombosis after total knee arthroplasty and the influence on hypercoagulation.@*METHODS@#Seventy-three patients of knee osteoarthritis with lower extremity venous thrombosis after total knee arthroplasty (KOA) were randomly divided into an observation group (37 cases, 2 cases dropped off) and a control group (36 cases, 1 case dropped off). The patients in the control group took orally rivaroxaban tablets, 10 mg a time, once a day. On the basis of the treatment as the control group, the aconite-isolated moxibustion was applied to Yongquan (KI 1) for the patients of the observation group, once daily and 3 moxa cones were used in each treatment. The duration of treatment was 14 days in both groups. Before treatment and 14 days into treatment, the ultrasonic B test was adopted to determine the conditions of lower extremity venous thrombosis in the two groups. Before treatment, 7 and 14 days into treatment, the coagulation indexes (platelet [PLT], prothrombin time [PT], activated partial prothrombin time [APTT], fibrinogen [Fib] and D-dimer[D-D]), the blood flow velocity of the deep femoral vein and the circumference of the affected side were compared between the two groups separately, and the clinical effect was evaluated.@*RESULTS@#Fourteen days into treatment, the venous thrombosis of the lower extremity was relieved in both groups (P<0.05), and that of the observation group was better than the control group (P<0.05). Seven days into treatment, the blood flow velocity of the deep femoral vein was increased compared with that before treatment in the observation group (P<0.05), and the blood flow rate in the observation group was higher than that in the control group (P<0.05). Fourteen days into treatment, PT, APTT and the blood flow velocity of the deep femoral vein were increased in the two groups compared with those before treatment (P<0.05); and PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all reduced in the two groups (P<0.05). Compared with the control group 14 days into treatment, the blood flow velocity of the deep femoral vein was higher (P<0.05), PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all lower in the observation group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 85.7% (30/35) in the control group (P<0.05).@*CONCLUSION@#Aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban can effectively treat lower extremity venous thrombosis after total knee arthroplasty, relieve hypercoagulation, accelerate the blood flow velocity and alleviate swelling of the lower extremity in the patients with knee osteoarthritis.

Postoperative subacute static progressive stretch does not increase the risk of distal lower limb venous thromboembolism / 中华创伤杂志(英文版)

PURPOSE@#Static progressive stretch (SPS) can be applied to treat chronic joint stiffness. However, the impacts of subacute application of SPS to the distal lower limbs, where deep vein thrombosis (DVT) is common, on venous thromboembolism remain unclear. This study aims to explore the risk of venous thromboembolism events following subacute application of SPS.@*METHODS@#A retrospective cohort study was conducted on patients diagnosed with DVT following a lower extremity orthopedic surgery before being transferred to the rehabilitation ward from May 2017 to May 2022. Patients with unilateral lower limb comminuted para-articular fractures, transferred to rehabilitation ward for further treatment within 3 weeks after operation, followed up more than 12 weeks since initial manual physiotherapy, and diagnosed DVT by ultrasound before rehabilitation course were included in the study. Patients with polytrauma, without evidence of previous peripheral vascular disease or incompetence, had medication for thrombosis treatment or prophylaxis before the operation, detected with paralysis due to nervous system impairment, infected after operation during the regime, or with acute progression of DVT were excluded. The included patients were randomized to the standard physiotherapy and the SPS integrated groups for observation. Associated DVT and pulmonary embolism data were collected during the physiotherapy course to compare the groups. SSPS 28.0 and GraphPad Prism 9 were used for data processing. A p < 0.05 was set significant difference.@*RESULTS@#In total of 154 patients with DVT participating in this study, 75 of them were treated with additional SPS for postoperative rehabilitation. The participants in the SPS group showed improved range of motion (12.3° ± 6.7°). However, in the SPS group, there was no difference in thrombosis volume between the start and termination (p = 0.106, p = 0.787, respectively), although difference was seen intra-therapy (p < 0.001). Contingency analysis revealed the pulmonary embolism incidence (OR = 0.703) in the SPS group compared to the mean physiotherapy.@*CONCLUSION@#The SPS technique is a safe and reliable option to prevent potential joint stiffness without aggravating the risk of distal DVT for postoperative patients suffering from relevant trauma.

Complicaciones en accesos venosos vasculares: estudio descriptivo de catéteres venosos centrales y catéteres de línea media / Complications in vascular venous access: descriptive study of central venous catheters and midline catheters

[RESUMEN]. Los accesos vasculares venosos son dispositivos elementales para el tratamiento hospitalario de diversas condiciones. Está bien documentada la tasa de complicaciones para catéteres venosos centrales (CVC) y catéteres de línea media (MD), pero existe un solo trabajo que los compara directamente. Por ello realizamos el presente trabajo con el objetivo de establecer las tasas generales y comparativas de complicaciones en ambos tipos de catéteres. Se realizo un estudio descriptivo retrospectivo donde se reclutaron 168 pacientes, los cuales recibieron 268 catéteres (120 accesos venosos centrales y 148 midline), con una media de edad de 45 años, con leve predominio del sexo femenino (51,2%). De estos, la principal comorbilidad fue neoplasia (57,1%). En el 29,8% el principal motivo de colocación fue la infusión de quimioterapia. Como resultados, la prevalencia de complicaciones fue del 19%: infecciosas en el 7,5% de los casos (con una tasa de infecciones asociadas a catéter de 4.9/1000 días catéter), 1,9% trombóticas y 9,7% mecánicas. La tasa de complicaciones fue mayor para los catéteres venosos centrales, no alcanzando una diferencia estadísticamente significativa: infecciosas (10.8% vs. 4,7%; p: 0,059; OD: 2.47; IC 95%: 0.94 - 6.34) y mecánicas (5.8% vs. 12,8%; p: 0,054; OD: 0.42; IC 95%: 0.17 ­ 1.03) para CVC y MD, respectivamente. Las complicaciones trombóticas fueron similares en ambos (1,6% en CVC y 2% en MD, p: 0,82).

[ABSTRACT]. Venous vascular accesses are fundamental devices for in hospital treatment of various conditions. Complication rates for central venous catheters (CVC) and midline catheters (MD) are well-documented, but there is only one study in wich both devices were compared. Therefore, we conducted the present study with the aim of establishing the overall and comparative complication rates of both types of catheters. We conducted a retrospective descriptive study recruiting 168 patients who received 268 catheters (120 central venous accesses and 148 midlines). The mean age was 45 years, with a slight predominance of females (51.2%). Among these, the main comorbidity was neoplasia (57.1%). In 29.8% of cases, the main reason for catheter placement was chemotherapy infusion. As a result, the prevalence of complications was 19%: infectious complications in 7.5% of cases (with a catheter-associated infection rate of 4.9/1000 catheter days), thrombotic 1,9%, and mechanical 9,7%. Complication rate were higher for central venous accesses, although the difference did not reach statistical significance: infectious (10.8% vs. 4.7%; p: 0.059; OR: 2.47; 95% CI: 0.94 - 6.34) and mechanical (5.8% vs. 12.8%; p: 0.054; OR: 0.42; 95% CI: 0.17 ­ 1.03) for CVC and MD, respectively.Thrombotic complications were similar in both (1.6% in CVC and 2% in MD, p: 0.82).

Clinical Comparison of the Efficacy of Systemic Thrombolysis,Catheter-Directed Thrombolysis,and AngioJet Percutaneous Mechanical Thrombectomy in Acute Lower Extremity Deep Venous Thrombosis / 中国医学科学院学报

Objective To compare the clinical effects of three treatment methods including systemic thrombolysis(ST),catheter-directed thrombolysis(CDT),and AngioJet percutaneous mechanical thrombectomy(PMT)in acute lower extremity deep venous thrombosis(LEDVT). Methods The data of 82 patients diagnosed with LEDVT in the Department of Vascular and Gland Surgery of the First Affiliated Hospital of Hebei North University from January 2017 to December 2020 were collected.The patients were assigned into a ST group(n=50),a CDT group(n=16),and a PMT group(n=16)according to different treatment methods.The efficacy and safety were compared among the three groups. Results Compared with that before treatment,the circumferential diameter difference of both lower limbs on days 1,2,and 3 of treatment in the ST,CDT,and PMT groups reduced(all P<0.001).The PMT group showed smaller circumferential diameter difference of lower limbs on days 1,2,and 3 of treatment than the ST group(all P<0.001)and smaller circumferential diameter difference of the lower patellar margin on day 1 of treatment than the CDT group(P<0.001).The PMT group showed higher diminution rate for swelling of the affected limb at the upper and lower edges of the patella than the ST group(P<0.001)and higher diminution rate for swelling at the upper edge of the patella than the CDT group(P=0.026).The incidence of complications after treatment showed no significant differences among the three groups(all P>0.05).The median of hospital stay in the PMT group was shorter than that in the ST and CDT groups(P=0.002,P=0.001).The PMT group had higher thrombus clearance rate than the ST group(P=0.002)and no significant difference in the thrombus clearance rate from the CDT group(P=0.361).The vascular recanalization rates in the PMT(all P<0.001)and CDT(P<0.001,P=0.002,P=0.009)groups 3,6,and 12 months after treatment were higher than those in ST group,and there were no significant differences between PMT and CDT groups(P=0.341,P=0.210,P=0.341). Conclusions ST,CDT,and PMT demonstrated significant efficacy in the treatment of LEDVT,and PMT was superior to ST and CDT in terms of circumferential diameter difference of the lower limbs,diminution rate for swelling of the affected limb,thrombus clearance rate,length of hospital stay,and long-term vascular recanalization.There was no obvious difference in safety among the three therapies.

Efficacy evaluation of novel oral anticoagulants in patients with cirrhosis accompanied with portal vein thrombosis: a meta-analysis / 中华肝脏病杂志

Objective: To analyze the safety and efficacy of using novel oral anticoagulants (rivaroxaban and others) in patients with cirrhosis accompanied with portal vein thrombosis (PVT). Methods: Clinical research literature published from the establishment of the database to June 20, 2021, was retrieved from PubMed, Web of Science, CNKI, Wanfang, and Weipu databases by combining subject terms and free words. RevMan software was used for the random group meta-analysis model. Results: In terms of PVT recanalization, the novel oral anticoagulants (such as low molecular weight heparin and others) had a higher recanalization rate than traditional anticoagulants (OR = 13.75, 95%CI 3.58-52.9, P = 0.000 1). In terms of bleeding, the novel oral anticoagulants did not increase the risk of bleeding compared with traditional anticoagulants (OR = 2.42, 95%CI 0.62-9.41, P = 0.20). Conclusion: The novel oral anticoagulant drugs are superior to traditional anticoagulants in terms of the occurrence of PVT recanalization; however, there is no statistically significant difference in terms of the occurrence of bleeding between the two groups.

Predictive value of three kinds of thrombosis risk assessment scale for lower extremity deep vein thrombosis after hip fracture in elderly patients / 中国骨伤

OBJECTIVE@#To explore predictive value of Caprini score, Wells score and Autar score for lower extremity deep vein thrombosis (DVT) after hip fracture in elderly patients.@*METHODS@#A total of 310 elderly patients with hip fracture were selected from January 2018 to September 2022. According to the lower extremity color ultrasound examination results, 155 patients with DVT were divided into thrombosis group, included 42 males and 113 females, aged from 60 to 101 years old with an average of (80.58±8.84) years old; and 155 patients without DVT were divided into control group, included 58 males and 97 females, aged from 60 to 94 years old with an average of (79.01±8.99) years old. Caprini score, Wells score and Autar score immediately after admission were collected and compared between two groups. Receiver operating characteristic (ROC) curve was used to evaluate predictive value of three thrombus risk assessment tables for DVT after hip fracture in elderly patients.@*RESULTS@#Caprini score, Wells score and Autar score in thrombus group were significantly higher than those in control group (P<0.001). ROC curve analysis results showed that the best cut-off value of Caprini score was 8.5 points, the sensitivity was 46.5%, the specificity was 99.4%, and area under the curve(AUC) was 0.763. The best cut-off value of Wells score was 1.5, the sensitivity was 100%, the specificity was 99.4%, and AUC was 0.998. The best cut-off value of Autar score was 10.5 points, the sensitivity was 58.1%, the specificity was 84.5%, and AUC was 0.717.@*CONCLUSION@#Caprini scale, Wells scale and Autar scale all have good predictive efficacy for the risk of DVT in elderly patients with hip fracture, and could provide an important reference for clinical guidance for prevention, management and treatment of DVT after hip fracture in elderly patients, among which Wells scale has a higher predictive value.

Correlation analysis of serum MMP-1 and MMP-2 levels with lower extremity deep venous thrombosis after operation for lower limb fracture / 中国骨伤

OBJECTIVE@#To investigate the relationship between serum matrix metalloproteinase-1(MMP-1) and matrix metalloproteinase-2(MMP-2) and the formation of deep venous thrombosis(LDVT) in lower extremity patients after surgery for lower extremity fracture, and to analyze the value of MMP-1 and MMP-2 in predicting the occurrence of LDVT after lower extremity fracture.@*METHODS@#From June 2018 to December 2021, 352 patients who planned to receive surgical treatment of lower limb fracture in our hospital were selected as the research objects. Venous blood was collected at 1, 2 and 3 days after surgery, respectively, and serum MMP-1 and MMP-2 levels were detected. The incidence of LDVT during hospitalization was analyzed, and the risk factors of postoperative LDVT in patients with lower limb fracture surgery and the predictive value of MMP-1 and MMP-2 for LDVT were analyzed.@*RESULTS@#LDVT occurred in 40 patients (LDVT group), the incidence of LDVT was 11.36%, and 312 patients did not occurred(no occurred group). The serum levels of MMP-1 and MMP-2 in LDVT group increased gradually after surgery; the serum levels of MMP-1 and MMP-2 in the no occurred group increased slightly after surgery at 2 days and then decreased at 3 days after surgery (P<0.01);the serum levels of MMP-1 and MMP-2 in LDVT group were higher than those in the no occurred group at 2 days and 3 days after surgery (P<0.05). Serum levels of MMP-1 and MMP-2 were positively correlated with serum levels of interleukin-6 (IL-6), IL-8 and tumor necrosis factor -α (TNF-α) in LDVT patients at 2 days and 3 days postoperatively (P<0.05). Operative time, MMP-1 and MMP-2 postoperative 3 days were related to the occurrence of LDVT after lower limb fracture (P<0.01). The area under the curve(AUC) predicted by MMP-1 and MMP-2 postoperative 3 days for LDVT after lower limb fracture was 0.738 and 0.744 respectively, and the AUC predicted by combined MMP-1 and MMP-2 was 0.910, which was higher than that predicted by single indicator(Z=2.819 and 2.025, P<0.05).@*CONCLUSION@#High levels of MMP-1 and MMP-2 after lower extremity fracture are closely related to the occurrence of LDVT, and 3 d mMP-1 and MMP-2 after surgery maybe used as evaluation indexes for LDVT risk prediction.

Analysis of the Incidence of Lower Limb Deep Venous Thrombosis and Its Related Risk Factors in the Postoperative Patients with Lung Cancer / 中国肺癌杂志

BACKGROUND@#Lung cancer is the first leading cause of morbidity and mortality among the malignant tumors, which has become a hot issue in current research. Clinically, lung cancer is divided into small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) according to the pathological types. NSCLC includes adenocarcinoma, squamous cell carcinoma and other types of lung cancer, accounting for about 80% of all lung cancer. Venous thromboembolism (VTE) includes deep venous thrombosis (DVT) and pulmonary embolism (PE), which is a recognized complication in lung cancer patients with higher morbidity and mortality. The aim of this study is to determine the incidence of DVT and reveal the risk factors for DVT in the postoperative patients with lung cancer.@*METHODS@#We collected 83 postoperative patients with lung cancer admitted to the Department of Lung Cancer Surgery, Tianjin Medical University General Hospital from December 2021 to December 2022. All these patients were examined by color Doppler ultrasound of lower extremity vein upon admission and after operation to analyze the incidence of DVT. In order to explore the possible risk factors for DVT in these patients, we further analyzed the correlations between DVT and their clinical features. At the same time, the changes of coagulation function and platelet were monitored to investigate the value of blood coagulation in the patients with DVT.@*RESULTS@#DVT occurred in 25 patients after lung cancer operation, and the incidence rate of DVT was 30.1%. Further analysis found that the incidences of postoperative lower limb DVT were higher in lung cancer patients of stage III+IV or over 60 years of age (P=0.031, P=0.028). D-Dimer level in patients with thrombosis was significantly higher than that in non-thrombus patients on the 1st, the 3rd, and the 5th day after operation (P<0.05), and there was no significant difference in platelets and fibrinogen (FIB) (P>0.05).@*CONCLUSIONS@#The overall incidence of DVT in our center after lung cancer patients operation was 30.1%. Late-stage and older postpatients were more likely to develop DVT, and these patients with higher D-Dimer values should be considered the possibility of VTE events.

Superior ophthalmic vein and cavernous sinus thrombosis associated with COVID-19: a case report / Trombose de veia oftálmica superior e seio cavernoso associada à COVID-19: relato de caso

ABSTRACT Cavernous sinus and superior ophthalmic vein thrombosis is a rare clinical condition, and little described in the literature. The clinical presentation is nonspecific and highly variable, and symptoms may include red eye, ophthalmoplegia, coma, and death. The main etiology results from infection of the paranasal sinuses. The final diagnosis must be made through imaging tests such as magnetic resonance imaging. We describe a case of cavernous sinus and superior ophthalmic vein thrombosis after COVID-19 infection in a 64-year-old patient with persistent ocular hyperemia and pain on eye movement. Ophthalmological examination showed preserved visual acuity, conjunctival hyperemia, dilation of episcleral vessels and retinal vascular tortuosity in the right eye. Magnetic resonance imaging confirmed the diagnosis. The association with the COVID-19 was raised, excluding other infectious causes. Enoxaparin and Warfarin were started with significant improvement in the ocular clinical presentation and maintenance of initial visual acuity after 12 months of follow-up.

RESUMO A trombose de seio cavernoso e veia oftálmica superior é uma condição clínica rara e pouco descrita na literatura. A apresentação clínica é inespecífica e altamente variável. Os sintomas podem incluir olho vermelho, oftalmoplegia, coma e morte. A etiologia principal resulta da infecção dos seios paranasais. O diagnóstico final deve ser efetuado por meio de exames de imagem, como ressonância magnética. Descrevemos um caso de trombose de seio cavernoso e veia oftálmica superior após COVID-19 em paciente de 64 anos e com quadro de hiperemia ocular persistente e dor à movimentação ocular. Ao exame oftalmológico, observou-se acuidade visual preservada, hiperemia conjuntival, dilatação de vasos episclerais e tortuosidade vascular retiniana em olho direito. A ressonância confirmou o diagnóstico. A associação com a COVID-19 foi levantada, excluindo-se demais causas infecciosas. Prescrevemos enoxaparina e varfarina, com melhora do quadro clínico ocular e manutenção da acuidade visual inicial após 12 meses de acompanhamento.
