ABSTRACT
Resumo A embolia pulmonar (EP) é a terceira maior causa de morte cardiovascular e a principal de morte evitável intra-hospitalar no mundo. O conceito PERT® (do inglês, pulmonary embolism response team) envolve seu diagnóstico e tratamento precoce e multidisciplinar. A trombose venosa profunda (TVP) é a sua causa inicial na maioria dos casos e é responsável por complicações como a recidiva tromboembólica, a síndrome pós-trombótica e a hipertensão pulmonar tromboembólica crônica. Uma abordagem inicial semelhante ao PERT nos casos de TVP ilíaco-femoral grave pode reduzir não apenas o risco imediato de EP e morte, mas também suas sequelas tardias. Novas técnicas percutâneas e aparatos de trombectomia mecânica para o tromboembolismo venoso (TEV) vêm demonstrando resultados clínicos encorajadores. Propomos o desenvolvimento de um conceito ampliado de resposta rápida ao TEV, que envolve não apenas a EP (PERT®) mas também os casos graves de TVP: o time de resposta rápida para o TEV (TRETEV®), ou do inglês Venous Thromboembolism Response Team (VTERT®).
Abstract Pulmonary embolism (PE) is the third leading cause of cardiovascular death and the main cause of preventable in-hospital death in the world. The PERT® (Pulmonary Embolism Response Team) concept involves multidisciplinary diagnosis and immediate treatment. Deep venous thrombosis (DVT) is the initial cause of most cases of PE and is responsible for complications such as chronic thromboembolic recurrence, postthrombotic syndrome, and chronic thromboembolic pulmonary hypertension. An aggressive approach to severe cases of iliofemoral DVT similar to the PERT® system can not only reduce the immediate risk of PE and death but can also reduce later sequelae. New percutaneous techniques and mechanical thrombectomy devices for venous thromboembolism (VTE) have shown encouraging clinical results. We propose the development of an expanded concept of rapid response to VTE, which involves not only PE (PERT®) but also severe cases of DVT: the Venous Thromboembolism Response Team (VTERT®).
ABSTRACT
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.

Venous thromboembolism (VTE), which entails the formation of a thrombus (blood clot) in a vein, has a significant disease burden worldwide. While VTE has traditionally been considered to predominantly affect Caucasian populations, recent studies have indicated a gradual shift in the disease burden towards Asian populations, with added significance of it being a key driver of post-operative mortality. It is imperative to develop a sound understanding of the various factors that affect VTE in stratified local populations. However, there is a glaring paucity of quality data on VTE and its ramifications among Indians - both in terms of quality of life and cost of healthcare. This review aims to throw light on the disease burden, epidemiology, risk factors, environmental factors, food and nutrition that plays a key role in VTE. We also explored the association of VTE with coronavirus disease 2019 to grasp the interplay between the two most significant public health crises of our time. It is vital to place a special emphasis on future research on VTE in India to plug the gaps, which exist in our current knowledge of the disease, particularly with respect to Indian population
ABSTRACT
Objective:To study the clinical application of hanging moxibustion in intervention of deep venous thrombosis (DVT) of lower extremity after intertrochanteric fracture of femur, in order to provide theoretical basis for the clinical application of suspension moxibustion.Methods:By adopting a controlled clinical trial method, a total of 100 patients with femoral intertrochanteric fracture who came to Keqiao District Hospital of Traditional Chinese Medicine, Shaoxing City, Zhejiang Province for orthopaedic surgery from January 2021 to September 2022 were selected by convenient sampling method and randomly divided into the control group and the observation group, 50 cases in each group. The control group was given routine nursing intervention, and the observation group was given the traditional Chinese medicine nursing intervention of hanging moxibustion on the basis of the control group. The changes of coagulation function indexes, hemorheology indexes, hemodynamics, the swelling degree score of the affected limb, and the Visual Analogue Scale (VAS) of the affected limb pain in the two groups of patients with intertrochanteric fracture before and 14 days after the intervention, and the incidence of lower extremity deep venous thrombosis (DVT) in the two groups after 1 d, 3 d, 7 d, and 14 d of intervention were observed and recorded.Results:After 14 days of intervention, D-dimer, fibrinogen and prothrombin time in the observation group were (380.64 ± 41.78) μg/L, (4.51 ± 0.49) g/L and (10.46 ± 1.04) s, respectively, which were better than those in the control group (464.91 ± 46.81) μg/L, (4.82 ± 0.56) g/L and (12.85 ± 1.12) s with statistical difference ( t=9.50, 2.95, 11.06, all P<0.05). After 14 days of intervention, the whole blood low tangential viscosity, whole blood high tangential viscosity and plasma viscosity in the observation group were (8.34 ± 0.42), (3.72 ± 0.28) and (1.21 ± 0.18) mPa/s, respectively, which were significantly lower than (8.90 ± 0.46), (4.13 ± 0.26) and (1.53 ± 0.22) mPa/s in the control group ( t=6.36, 7.59, 7.96, all P<0.05). After 14 days of intervention, the postoperative blood flow, maximum blood flow velocity and average blood flow velocity in the observation group were (1.89 ± 0.26) L/min, (31.57 ± 3.29) cm/s, (34.41 ± 3.62) cm/s, which were significantly higher than (1.45 ± 0.21) L/min, (24.18 ± 2.85) cm/s, (27.96 ± 3.15) cm/s in the control group ( t=9.31, 12.01, 9.50, all P<0.05). After 14 days of intervention, the total incidence of lower limb DVT in the observation group was 2.00%(1/50) , lower than 24.00%(12/50) in the control group, the difference between the two groups was significant ( χ2=10.70, P<0.05). Conclusions:Suspended moxibustion can significantly improve the coagulation function, hemorheology, hemodynamics, swelling and pain of the affected limb in patients with postoperative intertrochanteric fracture of the femur, and reduce the occurrence of DVT in the lower extremity. It is recommended to be widely used in clinical practice.
ABSTRACT
Objective:To analyze the relationship between preoperative deep vein thrombosis (DVT) and parameters of conventional coagulation tests (CCTs) and thromboelastography (TEG) in patients with acute trauma, and to establish a prediction model to screen out high-risk patients with preoperative DVT.Methods:The clinical data of patients with acute traumatic fracture admitted to the Emergency Intensive Care Unit of Shanghai Sixth People’s Hospital from January 2021 to June 2021 were retrospectively collected. According to whether preoperative DVT occurred, the patients were divided into the DVT group and non-DVT group. The differences of CCTs and TEG parameters at the same time were compared between the two groups. Logistic regression analysis was applied to identify independent risk factors for DVT after trauma. The receiver-operating characteristic curve analysis was employed to analyze the clinical value of those parameters to predict preoperative DVT.Results:Among 123 patients with acute traumatic fracture, 101 patients were treated with anticoagulation before operation, and 51 patients were diagnosed with DVT. There were significant differences in activated partial thromboplastin time, fibrinogen (Fib), D-Dimer, fibrinogen degradation products (FDPs), reaction time, clotting time, α angle, maximum amplitude (MA) and coagulation index between the DVT and non-DVT groups. D-Dimer and MA were independent risk factors for preoperative DVT in patients with traumatic fracture. Logistic regression equation was used to establish a prediction model: the predicting index = 0.101×D-Dimer +0.241×MA + (-18.190). The α angle (AUC=0.833, P<0.001), MA (AUC=0.904, P<0.001), coagulation index (AUC=0.914, P<0.001) of TEG versus Fib (AUC=0.684, P=0.001), D-Dimer (AUC=0.685, P<0.001) and FDPs (AUC=0.656, P=0.003) of CCTs had a higher diagnostic efficacy in developing DVT of lower extremity in patients with traumatic fracture, and of all the coagulation index was the best. However, the predictor of D-Dimer combined with MA had a better predictive value (AUC=0.926, P<0.001), and the best cut-off value was 0.32 with a sensitivity and specificity of 90.2% and 79.8%, respectively. Conclusions:Compared with CCTs, TEG has more advantages in predicting preoperative DVT in patients with traumatic fracture, and the predictor of D-Dimer combined with MA can screen out patients with high risk of DVT, which can be recommended for clinical application.
ABSTRACT
Venous thromboembolism (VTE) is a common perioperative complication in patients with malignant tumors. Factors such as colorectal cancer itself and surgical treatment can increase the risk of perioperative VTE. In recent years, with the development of the concept of enhanced recovery after surgery, the understanding of cancer-associated venous thrombosis has deepened, and significant progress has been made in the risk assessment, prevention and treatment strategies of cancer-associated VTE. This article will review the pathogenesis, risk factors, risk assessment, prevention and treatment strategies of colorectal cancer-associated VTE, in order to provide evidence-based medical basis and research ideas for the standardized management and future research of colorectal cancer-associated VTE.
ABSTRACT
Total knee arthroplasty， as a common treatment option for advanced knee osteoarthritis， can alleviate the clinical symptoms of patients. Deep vein thrombosis of the lower extremity is the most common complication of total knee arthroplasty. Previous studies have shown that the occurrence of deep vein thrombosis after total knee arthroplasty is mostly related to the overexpression of inflammatory factors in vivo. Nuclear transcription factor-κB， Toll-like receptor 4， phosphatidylinositol 3-kinase/protein kinase B， tumor necrosis factor， and nuclear transcription factor E2-related factor 2 are typical signaling pathways related to inflammation. Regulating the expression of the signaling pathways can intervene the formation of inflammatory factors. Inhibiting the formation of inflammatory factors can help suppress the activation of platelets， thereby blocking thrombosis. According to previous research， Chinese medicine monomers， Chinese medicine extract， and compound Chinese medicine prescriptions all directly or indirectly inhibit the expression of inflammatory factors by regulating the above signaling pathways， thereby suppressing the occurrence of deep vein thrombosis after total knee arthroplasty. Therefore， Chinese medicine can reduce postoperative complications and promote postoperative recovery of patients at low cost with small side effects. This article summarizes the research on Chinese medicine intervention on deep vein thrombosis-related signaling pathways after total knee arthroplasty， which is expected to lay a basis for the in-depth study and clinical application of Chinese medicine in deep vein thrombosis.
ABSTRACT
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.

Abstract Background Deep vein thrombosis of the lower extremities is associated with a significant burden of comorbidities. Objectives In this study, our objective was to investigate the presence of seasonal variation in deep vein thrombosis (DVT) and assess the location of the thrombus. Methods Out of 8177 patients admitted to two university hospitals and referred to outpatient clinics, we included a total of 611 consecutive patients (316 females, 295 males) diagnosed with acute deep vein thrombosis in this retrospective study. The mean age of the patients was 59.35±18.49 years, ranging from 1 to 96 years. Patients were categorized into four groups by age. Results DVT was found to be more frequent in the summer (n = 190 or 31%, p = 0.003) and specifically in August (n = 65 or 10.6%, p = 0.014), while it was least frequent in the spring (n = 128 or 20.9%) and in May (n = 40 or 6.5%). However, when comparing seasons, no significant differences were observed in terms of seasonal variation (p = 0.062) or monthly variation (p = 0.143). Conclusions Contrary to previous studies, this study demonstrated a higher occurrence of DVT during the summer, particularly in August. However, it did not reveal a clear seasonal pattern. One plausible explanation for these findings could be the adverse winter conditions and transportation challenges within the province, which may result in fewer DVT patients being able to reach hospitals for timely treatment.
Resumo Contexto A trombose venosa profunda (TVP) dos membros inferiores está associada a uma carga significativa de comorbidades. Objetivos Investigar a presença de variação sazonal na TVP e identificar a localização do trombo. Métodos Dos 8.177 pacientes internados em dois hospitais universitários e encaminhados para ambulatórios, incluímos um total de 611 pacientes consecutivos (316 mulheres, 295 homens) diagnosticados com TVP aguda neste estudo retrospectivo. A idade média dos pacientes foi de 59,35±18,49 anos, variando de 1 a 96 anos. Os pacientes foram categorizados em quatro grupos com base na idade. Resultados A TVP foi mais frequente no verão (n = 190 ou 31%, p = 0,003), especificamente em agosto (n = 65 ou 10,6%, p = 0,014), e menos frequente na primavera (n = 128 ou 20,9%) e em maio (n = 40 ou 6,5%). No entanto, ao comparar as estações, não foram observadas diferenças significativas em termos de variação sazonal (p = 0,062) e variação mensal (p = 0,143). Conclusões Ao contrário de estudos anteriores, este estudo demonstrou maior ocorrência de TVP no verão, principalmente em agosto. No entanto, não revelou um padrão sazonal claro. Explicações plausíveis para essas descobertas seriam as condições adversas do inverno e dificuldades de deslocamento, o que pode resultar em menos pacientes com TVP chegando aos hospitais para tratamento oportuno.
ABSTRACT
Resumo Contexto O tromboembolismo venoso (TEV) é a terceira doença cardiovascular mais comum e a principal causa de óbito evitável em pacientes internados. Apesar de diretrizes bem estabelecidos na literatura, a profilaxia dessa afecção ainda é subutilizada. Estudos apontam taxa de adequação da profilaxia próxima de 50% mundialmente. Objetivos Avaliar a adequação da estratificação de risco e da prescrição de medidas de profilaxia do TEV em um hospital universitário terciário. Métodos Estudo transversal observacional realizado através da coleta de dados de prontuário. Foram incluídos pacientes adultos internados em diferentes especialidades e divididos em grupos cirúrgico e clínico. A estratificação de risco de TEV realizada pelos médicos assistentes foi comparada com a realizada pelos médicos pesquisadores, com base nas diretrizes recentes. A prescrição de medidas de profilaxia realizadas pelos médicos assistentes foi comparada com as recomendações das diretrizes, obtendo assim a taxa de adequação da profilaxia. Resultados Foram avaliados 400 pacientes, sendo 169 (42,3%) cirúrgicos e 231 (57,7%) clínicos. A taxa geral de adequação da estratificação foi de 50,8%. Nos grupos cirúrgico e clínico, as taxas de adequação foram respectivamente 39,1% e 59,3% (p < 0,0001). A taxa geral de adequação da profilaxia foi de 71,5%, enquanto no grupo cirúrgico foi de 78,1% e no grupo clínico de 66,7% (p = 0,0137). Conclusões A adequação da estratificação de risco para TEV foi baixa, demonstrando a pouca conscientização dos médicos assistentes sobre esse problema. No entanto, as taxas de adequação da prescrição de medidas de profilaxia estão superiores às de dados globais.
Abstract Background Venous thromboembolism is the third most common cardiovascular disease and the main cause of preventable death in hospitalized patients. Prophylaxis is still underused, despite well-established guidelines in the literature. Studies show a worldwide prophylaxis adequacy rate close to 50%. Objectives To assess the adequacy of risk stratification and prophylactic measures for venous thromboembolism in a tertiary university hospital. Methods A cross-sectional observational study was carried out, collecting data from medical records. Adult patients hospitalized by different specialties were enrolled and divided into surgical and clinical groups. The risk stratification of venous thromboembolism performed by the attending physicians was compared with stratification based on recent guidelines performed by the research physicians. Prophylaxis measures prescribed by the attending physicians were compared with guideline recommendations, thus obtaining the prophylaxis adequacy rate. Results 400 patients were analyzed, 169 (42.3%) surgical and 231 (57.7%) clinical. The overall stratification adequacy rate was 50.8%. Adequacy rates were 39.1% and 59.3% in the surgical and clinical groups respectively (P < 0.0001). The overall prophylaxis adequacy rate was 71.5%, with 78.1% in the surgical group and 66.7% in the clinical group (P=0.0137). Conclusions Risk stratification adequacy is low, demonstrating a low awareness among prescribing physicians of the need for adequate stratification for prescription of prophylaxis. However, the prophylaxis prescription adequacy rates are higher than those in global data.
ABSTRACT
OBJECTIVE To investigate the influence of Huayu xiaozhong decoction （HXD） on inflammatory response in rats with deep vein thrombosis （DVT）. METHODS The male SD rats were divided into control group （CK group）， model group （Model group）， HXD low-dose group （HXD-L group， HXD 10.86 mg/kg）， HXD medium-dose group （HXD-M group， HXD 21.71 mg/kg）， HXD high-dose group （HXD-H group， HXD 32.57 mg/kg）， positive control group （LMWHS group， low molecular weight heparin sodium 600 IU/kg）， silent information regulator 2 （SIRT2） inhibitor group （AK-7 group， AK-7 20 mg/kg）， HXD-M+AK-7 group （HXD 21.71 mg/kg+AK-7 20 mg/kg）， with 12 rats in each group. Except for the CK group， the DVT rat was induced by the Reyers method in other groups； after modeling， administration groups were given relevant medicine intragastrically/intraperitoneally， once a day， for consecutive 2 weeks. Twenty-four hours after the last medication， the coagulation function indexes [activated partial thromboplastin time （APTT）， thrombin time （TT）， prothrombin time （PT）， fibrinogen （FIB）] and inflammatory indexes in serum and inferior vena cava tissue [interleukin-1β （IL-1β）， IL-6， tumor necrosis factor-α （TNF-α）] of rats were detected. The formation of thrombus was observed， and the wet and dry masses of the thrombus were weighed. The protein expressions of tissue factor （TF） and SIRT2 as well as the phosphorylation and acetylation levels of nuclear factor kappa B （NF-κB） p65 in inferior vena cava tissue were detected. RESULTS Compared with CK group， APTT， TT and PT of rats in Model group were shortened significantly（P＜0.05）； the content of FIB， the levels of IL-1β， IL-6 and TNF-α， wet weight and dry weight of venous thrombus， TF protein staining score， the phosphorylation and acetylation levels of NF-κB p65 protein increased significantly （P＜0.05）； the inferior vena cava was full of thrombus， and the protein expression of SIRT2 decreased （P＜0.05）. Compared with Model group， above indexes of HXD-L group， HXD-M group， HXD-H group and LMWHS group were improved， while the improvement effects of HXD-M group， HXD-H group and LMWHS group were significantly better than those of HXD-L group （P＜0.05）. The trends of the corresponding indicators in AK-7 group were opposite to the above （P＜0.05）； AK-7 attenuated the inhibitory effect of medium-dose HXD on the inflammatory response in model rats （P＜0.05）.CONCLUSIONS HXD may inhibit the inflammatory response of DVT rats by activating SIRT2/NF-κB signaling pathway.
ABSTRACT
@#A 55-year-old women was diagnosed with Baker’s cyst and underwent open Baker’s cyst excision. She had developed acute pulmonary embolism in the post-operative period. Our case report is to emphasise the sub-clinical concomitant deep vein thrombosis with Baker’s cyst. Such a fatal complication has not been reported in literature and preventive measures of pre-operative venous Doppler and post-operative thrombo-prophylaxis can prevent them.
ABSTRACT
Objective:To explore the risk factors for lower extremity deep vein thrombosis (DVT) in patients with a spinal cord injury (SCI).Methods:The medical records of 276 hospitalized SCI patients were analyzed retrospectively. They were divided into a DVT group ( n=63) and a no-DVT group ( n=213). Gender, age, blood type, smoking history, surgical history, the time from SCI to admission, cause of SCI, fracture, SCI segments, American Spinal Cord Injury Association grade and complications were compared between the two groups. Binomial logistic regression was used to isolate the risk factors for lower extremity DVT among such patients. Results:Among 84% of the 63 with a lower extremity DVT, it was a calf muscle venous thrombosis. Anemia, hyponatremia and time from SCI to admission (which ranged from 74 to 195 days) were the most serious DVT risk factors.Conclusions:SCI patients are of high risk for DVT, with anemia and hyponatremia being independent risk factors.
ABSTRACT
Objective:To evaluate the efficacy and safety of of rivaroxaban for different doses in the treatment of isolated distal deep vein thrombosis.Methods:The clinical data of 853 patients of isolated distal deep vein thrombosis attending Nanjing Drum Tower Hospital from Jan 2018 to Dec 2020 was retrospectively analyzed.Results:Thrombotic recurrence rate increased with increasing follow-up in the standard and low dose groups, and it was significantly lower in the standard dose group than in the low dose group (HR=0.44, 95% CI: 0.25-0.78, P=0.005) with most thrombosis occurring within the first year of follow-up. There was no statistical difference between the two groups in terms of major bleeding events (HR=1.70,95%CI 0.56-5.14, P=0.530) and the incidence of clinically relevant non-major bleeding events was significantly higher in the standard dose group than in the low dose group (HR=2.36, 95%CI 1.26-4.44, P=0.020). Subgroup analysis on anticoagulation duration found when anticoagulation duration was longer than 1.5 months, the risk of thrombosis was lower in the standard dose group than the low dose group (1.5-3 months:HR=0.11, 95%CI 0.01-0.87, >3 months: HR=0.19, 95%CI 0.04-0.95), there was an interaction between anticoagulation duration and dose ( P=0.007). Conclusions:Based on the risk of thrombosis recurrence and bleeding events, the standard dose of rivaroxaban (20 mg qd) is recommended for patients with isolated distal deep vein thrombosis, and the anticoagulant duration should be maintained for 1.5 months or more.
ABSTRACT
Introducción: La enfermedad tromboembólica venosa es un trastorno en el que se forma un trombo en el interior de las venas, que bloquea el flujo sanguíneo y produce diferentes sintomatologías en función de su localización. Objetivos: Definir las características clínicas y epidemiológicas de los pacientes con trombosis venosa profunda y cáncer. Métodos: Se realizó un estudio descriptivo y retrospectivo de los pacientes que ingresaron en el Servicio de Flebolinfología del Instituto Nacional de Angiología y Cirugía Vascular, con el diagnóstico de trombosis venosa profunda y cáncer, durante el período entre enero y diciembre de 2018. Se estudiaron las siguientes variables: grupos de edad, sexo, diagnóstico al ingreso, factores de riesgo, tipos de cáncer y localización de la trombosis según Eco-Doppler. Resultados: El grupo de edad predominante fue 60-69 años (30,8 por ciento) y prevaleció el sexo femenino (61,5 por ciento). Sobresalió la localización del cáncer en las mamas y la próstata con tres casos cada uno (23,1 por ciento). El factor de riesgo predominante resultó la edad (38,4 por ciento), seguido por la presencia de metástasis (23,1 por ciento). Como sector predominante, según Eco-Doppler, se halló el femoropoplíteo (58,8 por ciento). Conclusiones: La trombosis venosa profunda afecta en gran medida a los pacientes con cáncer. Los más afectados tienen entre 60 y 69 años. Los factores de riesgo predominantes fueron la edad y la presencia de metástasis; y la localización más frecuente, los miembros inferiores, en específico, a nivel del sector femoropoplíteo(AU)

Lower extremity venous thromboembolism in the presence of soft tissue infection (cellulitis/erysipelas) is difficult to diagnose using clinical findings alone. This leads to an overuse of Doppler ultrasound, which is unnecessary in many cases. In Colombia, there are no studies to date reporting the simultaneous prevalence of these two conditions. Objective: to determine which factors are related to deep vein thrombosis in patients with lower extremity cellulitis/erysipelas. Materials and methods: a case-control study. Patients seen at Hospital Pablo Tobón Uribe and the university hospital between January 2018 and December 2019 who were diagnosed with cellulitis/erysipelas and underwent lower extremity venous Doppler. Demographic, clinical, laboratory and imaging variables were considered. Results: altogether, 637 patients with a diagnosis of lower extremity cellulitis and erysipelas were found during the study period in both institutions. Of these, 18.5% (118 patients) had a lower extremity Doppler ultrasound ordered to rule out deep vein thrombosis, finding a total of 25 positive studies (21.19%). Out of the total sample, 56 (47.4%) were male, with a mean age of 65 years. Most of the cases (55.08%) had an intermediate risk according to the Wells scale. The most common patient factors related to thrombosis were: immobility 33%, lymphedema 29.66%, and chronic kidney disease 23.73%. Neoplasms were the factor which showed statistical significance for the presence of thrombosis OR 5 (1.64-15.16) (P=0.0056). Conclusions: cellulitis is not a unique finding to justify carrying out a Doppler test, and the routine use of this imaging technique in the diagnostic approach is not justified if there are no other risk factors for thrombosis. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2109).
El diagnóstico de enfermedad tromboembólica venosa de miembros inferiores en presencia de infección de tejidos blandos (celulitis/erisipela): es difícil de determinar con sólo los hallazgos clínicos, lo que lleva a un sobreuso de la ecografía Doppler que resulta innecesaria en muchos casos. En Colombia a la fecha no hay estudios que reporten la prevalencia simultánea de éstas dos condiciones. Objetivo: determinar cuáles son los factores que se relacionan con trombosis venosa profunda (TVP) en pacientes con celulitis/erisipela en miembros inferiores. Materiales y métodos: estudio de casos y controles. Pacientes atendidos en el Hospital Pablo Tobón Uribe y la IPS universitaria entre enero de 2018 y diciembre de 2019 con diagnóstico de celulitis/erisipela y a quienes se les realizó Doppler venoso de miembros inferiores. Se consideraron variables demográficas, clínicas, paraclínicas e imagenológicas. Resultados: en total se identificaron 637 pacientes con diagnóstico de celulitis y erisipela de miembros inferiores en el periodo de estudio en ambas instituciones. De estos en 18.5% (118 pacientes) se solicitó ecografía Doppler de miembros inferiores para descartar trombosis venosa profunda, encontrando un total de 25 estudios positivos (21.19%). Del total de esta muestra fueron 56 hombres (47.4%) con una media de edad de 65 años. La mayoría de casos (55.08%), tuvieron riesgo intermedio según la escala de Wells. Los antecedentes más frecuentes relacionados con trombosis fueron: inmovilización 33%, linfedema 29.66%, enfermedad renal crónica 23.73%. La presencia de neoplasia fue el antecedente que demostró significancia estadística para la presencia de trombosis OR 5 (1.64-15.16) (P=0.0056). Conclusiones: la presencia de celulitis no es un hallazgo único que justifique la realización de Doppler, y el uso de imagen de rutina dentro del abordaje diagnóstico no está justificado si no existen otros factores de riesgo de trombosis.

ABSTRACT
Recurrent erythema nodosum leprosum (ENL) is a type 2 leprosy reaction, which often poses a challenge for the treating physician. Patient may be non-ambulatory due to systemic symptoms like fever, body aches, joint pains, and painful skin lesions. Moreover, drugs like corticosteroids and thalidomide in refractory cases pose an increased risk of deep vein thrombosis (DVT). We have described a case who developed DVT in due course of the treatment.
ABSTRACT
Background & objectives: Paroxysmal nocturnal haemoglobinuria is a rare acquired disease characterized by bone marrow failure, intravascular haemolysis and thrombophilia. Thrombosis is the deadliest complication of paroxysmal nocturnal haemoglobinuria (PNH). The present study was conducted to study the prevalence of PNH in cases of deep vein thrombosis (DVT) which was previously undocumented from western Rajasthan. Methods: In the present cross-sectional study, 61 adult patients with DVT were tested using flow cytometry to detect PNH clones. Blood samples were processed using fluorescein-labelled proaerolysin, CD14, CD24, CD33 and CD45 panels for granulocytes and monocytes and CD59 and CD235a panel for red blood cells. Results: Three cases (4.92%) having large clones on monocytes as well as granulocytes, which fulfilled the diagnostic criteria of PNH were detected. Further, three cases (4.92%) showed small clones on both granulocytes and monocytes. Nine (15%) cases showed small clones only on granulocytes, and 11 (18%) cases showed small clones only on monocytes. Interpretation & conclusions: The results of the present study suggest that a higher proportion of patients had PNH in western Rajasthan compared to previously reported studies from elsewhere. It is suggested that PNH testing should be added to the procoagulant work-up panel in institutions of this region where it is not routinely done. This provides an otherwise missed opportunity to diagnose this disorder. Eculizumab may be employed, which is effective in reducing thrombophilic events in cases of PNH
