OBJECTIVE@#To observe the clinical effect of moxibustion combined with plucking technique at Jiquan (HT 1) for preventing peripherally inserted central catheter (PICC)-related venous thrombosis in the upper limbs of malignant tumor patients.@*METHODS@#A total of 80 malignant tumor patients undergoing PICC were randomized into an observation group and a control group, 40 cases in each one. In the control group, the routine care for PICC was exerted. In the observation group, besides the routine care, moxibustion combined with plucking technique at Jiquan (HT 1) was added. Mild moxibustion was exerted along the venous distribution of PICC (avoiding the entry site) for 10 to 15 min, and then, the circling moxibustion was applied to Quchi (LI 11), Xuehai (SP 10) and Tianfu (LU 3), 3 to 5 min at each acupoint. Finally, plucking technique was given at Jiquan (HT 1) for 5 to 10 min. This combined therapy was intervened since the 2nd day of PICC placement, once daily, 5 times a week, for 3 weeks totally. The incidence of the PICC-related venous thrombosis in the upper limbs was compared between the two groups on day 42 of placement. On day 2, 7, 14, 21, 28, 35 and 42 of PICC placement, the peak systolic velocity (PSV) and the end-diastolic velocity (EDV) of the subclavicular vein on the placement side were observed separately in the two groups.@*RESULTS@#The incidence of the PICC-related venous thrombosis in the upper limbs in the observation group was lower than that in the control group (2.5% [1/40] vs 17.5% [7/40], P<0.05). From day 7 to 35 of PICC placement, PSV of the subclavicular vein on the placement side was higher than that on the day 2 of PICC placement in the observation group (P<0.05). On day 28 and 42 of PICC placement, PSV of the subclavicular vein on the placement side was lower than that on the day 2 of PICC placement in the control group (P<0.05). In the observation group, EDV of the subclavicular vein on the placement side was higher than that on the day 2 of PICC placement from day 7 to 28 of PICC placement (P<0.05). In the control group, EDV of the subclavicular vein on the placement side from day 28 to 42 of PICC placement was lower than that on the day 2 of PICC placement (P<0.05). From day 7 to 42 of PICC placement, PSV and EDV of the subclavicular vein on the placement side in the observation group were all higher than those in the control group (P<0.01, P<0.05).@*CONCLUSION@#The combined treatment of moxibustion with plucking technique at Jiquan (HT 1) can effectively prevent PICC-related venous thrombosis in the upper limbs and improve venous blood flow velocity in malignant tumor patients.

Objective: To investigate the predictive value of D-dimer for deep venous thrombosis (DVT) of lower extremity in adult burn patients. Methods: A retrospective case series study was conducted. The clinical data of 3 861 adult burn patients who met the inclusion criteria and were admitted to the Department of Burns of Zhengzhou First People's Hospital from January 1, 2015 to December 31, 2019 were collected. The patients were divided into DVT group (n=77) and non-DVT group (n=3 784) according to whether DVT of lower extremity occurred during hospitalization or not. Data of patients in the two groups were collected and compared, including the gender, age, total burn area, D-dimer level, with lower limb burn and inhalation injury or not on admission, with sepsis/septic shock, femoral vein indwelling central venous catheter (CVC), history of surgery, and infusion of concentrated red blood cells or not during hospitalization. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, and chi-square test. The indicators with statistically significant differences between the two groups were analyzed with multivariate logistic regression analysis to screen the independent risk factors for DVT of lower extremity in 3 861 adult burn patients. The receiver operating characteristic (ROC) curve of the independent risk factors predicting DVT of lower extremity in 3 861 adult burn patients were drawn, and the area under the curve (AUC), the optimal threshold value, and the sensitivity and specificity under the optimal threshold value were calculated. The quality of the AUC was compared by Delong test, and the sensitivity and specificity under the optimal threshold value were compared using chi-square test. Results: There were no statistically significant differences in gender, occurrence of sepsis/septic shock or history of surgery during hospitalization between patients in the two groups (P>0.05), while there were statistically significant differences in age, total burn area, D-dimer level, lower limb burn and inhalation injury on admission, and femoral vein indwelling CVC and infusion of concentrated red blood cells during hospitalization between patients in the two groups (t=-8.17, with Z values of -5.04 and -10.83, respectively, χ2 values of 21.83, 5.37, 7.75, and 4.52, respectively, P<0.05 or P<0.01). Multivariate logistic regression analysis showed that age, total burn area, and D-dimer level were the independent risk factors for DVT of lower extremity in 3 861 adult burn patients (with odds ratios of 1.05, 1.02, and 1.14, respectively, 95% confidence intervals of 1.04-1.06, 1.00-1.03, and 1.10-1.20, respectively, P<0.05 or P<0.01). The AUCs of ROC of age, total burn area, and D-dimer level for predicting DVT of lower extremity in 3 861 adult burn patients were 0.74, 0.67, and 0.86, respectively (with 95% confidence intervals of 0.68-0.80, 0.60-0.74, and 0.83-0.89, respectively, P values<0.01), the optimal threshold values were 50.5 years old, 10.5% total body surface area, and 1.845 mg/L, respectively, the sensitivity under the optimal threshold values were 71.4%, 70.1%, and 87.0%, respectively, and the specificity under the optimal threshold values were 66.8%, 67.2%, and 72.9%, respectively. The AUC quality and sensitivity and specificity under the optimal threshold value of D-dimer level were significantly better than those of age (z=3.29, with χ2 values of 284.91 and 34.25, respectively, P<0.01) and total burn area (z=4.98, with χ2 values of 326.79 and 29.88, respectively, P<0.01), while the AUC quality and sensitivity and specificity under the optimal threshold values were similar between age and total burn area (P>0.05). Conclusions: D-dimer level is an independent risk factor for DVT of lower extremity in adult burn patients, its AUC quality and sensitivity and specificity under the optimal threshold value are better than those of age and total burn area, and it has good predictive value for DVT of lower extremity in adult burn patients.

OBJECTIVE@#To investigate the effectiveness of modified Caprini risk assessment model(Caprini MRAM) in predicting the risk of deep venous thrombosis (DVT) after total knee arthroplasty (TKA).@*METHODS@#A case-control study was used to collect 43 patients with DVT after TKA in lower limb department of Sichuan Orthopedic Hospital from January 2016 to November 2020 in the positive group, and 172 patients without DVT after TKA in the same period according to the 1∶4 ratio between positive and control group were selected in the control group. Caprini MRAM was used to score and grade the risk of DVT. The clinical data, score and risk classification of the two groups were compared. The relationship between the risk of DVT in the patients after TKA and the risk factors in the risk ckassification and assessment of Caprini MRAM was analyzed by multivariate logistic regression model.@*RESULTS@#The average score of caprini in DVT group was significantly higher than that in control group[(8.11±2.91) vs(4.07±2.12), P<0.001];DVT group was mainly at medium and high risk group(66.67%), while the control group was mainly at low risk (77.33%). There was a significant difference between the two groups in risk classification composition (P<0.001). BMI≥30 kg/m2, lower extremity edema (<1 month), severe pulmonary disease (<1 month), acute myocardial infarction (<1 month), bed rest (> 2 h), history of superficial or deep vein or pulmonary embolism and family history of thrombosis were the main risk factors for DVT in patients after TKA(all P<0.05). Preoperative D-dimer elevation (OR=4.380), BMI≥30 kg/m2(OR=2.518), lower extremity edema(<1 month)(OR=7.652), acute myocardial infarction (<1 month) (OR=1.994), bed rest (> 72 h)(OR=3.897), history of superficial or deep vein or pulmonary embolism (OR=13.517) and family history of blood embolism (OR=6.551) were independent risk factors for DVT in patients after TKA (all P<0.05). The risk of DVT was 13.457 and 2.739 times higher in high and moderate risk TKA patients with Caprini MRAM classification, respectively.@*CONCLUSION@#Caprini MRAM can be used to predict the risk of DVT in patients after TKA, especially for patients with high risk.

Neurofibromatosis type 1 (NF1) is a genetic syndrome which typically presents with neurological manifestations. Some of the patients may also present with vasculopathies, among which arterial aneurysms and stenosis are the most common. Deep vein thrombosis (DVT) has rarely been described, and, to the best of our knowledge, the present is the first report of DVT due to venous compression by a neurofibroma in the setting of NF1. This is the case of a 23-year-old male with NF1 who experienced DVT due to compression of the left posterior tibial veins by a large tumor arising from the tibial nerve. The DVT was acutely treated with enoxaparin and then with rivaroxaban. Two months after the diagnosis, Doppler ultrasonography showed partial recanalization and persistence of the DVT. The patient was then referred to neurosurgery for surgical resection of the tumor. There were no complications during the procedure, and the patient did not present postoperative neurological deficits. The final histopathological diagnosis was of a benign neurofibroma. After one year of follow-up with vascular surgery, the patient presented no more episodes of DVT. In case there is a tumor compressing the deep vessels of the leg and promoting DVT, surgical resection with microsurgical techniques may be curative.

ABSTRACT BACKGROUND: Vitamin D has relationships with pathogenesis and inflammation pathways in many diseases. Its deficiency may make clinicians think not only of supplementation but also of presence of other diseases. OBJECTIVE: To investigate the relationship between vitamin D levels and deep vein thrombosis (DVT), given that reduced levels are related to increased risk of cardiovascular diseases. DESIGN AND SETTING: Case-control study conducted in the cardiovascular surgery and family medicine departments of a hospital in Turkey. METHODS: A total of 280 participants were included: 140 each in the DVT and control groups. Basic clinical characteristics, comorbidities and serum 25-hydroxyvitamin D (25(OH)D) levels were recorded and then compared between the groups. Serum 25(OH)D levels were also evaluated separately in three subgroups (sufficient, insufficient and deficient). RESULTS: Serum 25(OH)D levels were significantly lower in the DVT group than in the controls (P < 0.001). Females in the DVT group had lower 25(OH)D levels than those in the control group (P = 0.002). Nonetheless, the median 25(OH)D level (16.41 ng/ml) of the control group was still below the reference value. Logistic regression analysis showed that 25(OH)D was a significant predictor of DVT. Weight, height and body mass index, which all presented interaction, were significant in the logistic regression analysis but not in individual analyses. CONCLUSION: The serum vitamin D levels of DVT patients were lower than those of controls. If the results obtained from our study are supported by further large-scale randomized controlled trials, vitamin D replacement may be brought into the agenda for protection against DVT.

Resumo A agenesia de veia cava inferior é descrita em menos de 1% da população, de ocorrência rara e devido a alterações embrionárias. Sua correlação com a trombose venosa profunda certamente é subestimada, visto que tal alteração é de difícil detecção pela ultrassonografia. O objetivo deste artigo foi relatar o caso de uma paciente de 41 anos com dor e edema até a raiz de coxa direita após cirurgia plástica. Foi realizado dúplex venoso de membros inferiores e evidenciada trombose venosa profunda ilíaco-femoro-poplíteo e distal bilateralmente. Solicitado angiotomografia venosa devido a não visualização de veia cava inferior no ultrassom, evidenciando trombose de plexo lombar direito e segmento ilíaco-femoral bilateral, além de agenesia de segmento infra-hepático de veia cava inferior, com ectasia e tortuosidade compensatória de veias paravertebrais, sistema ázigos e hemiázigos, com varizes pélvicas bilateralmente. Foi realizada anticoagulação sistêmica e oral, com boa evolução clínica.

Abstract Agenesis of the inferior vena cava (IVC) has been described in less than 1% of the population; a rare occurrence caused by embryonic abnormalities. Its correlation with deep vein thrombosis (DVT) is certainly underestimated, since this change is hard to detect using ultrasound. The aim of the article is to report the case of a 41-year-old female patient with pain and edema up to the top of the right thigh after plastic surgery. Bilateral venous duplex ultrasound revealed bilateral DVT involving iliac-femoral-popliteal and distal segments. Venous angiotomography was requested because the IVC was not visible on ultrasound, revealing thrombosis of the right lumbar plexus and iliofemoral segment bilaterally and agenesis of the infrahepatic segment of the inferior vena cava, with ectasia and compensatory tortuosity of paravertebral veins and the azygos-hemiazygos system, and bilateral pelvic varices. Systemic and oral anticoagulation were administered, with a satisfactory clinical response.

Popliteal artery aneurysms is the most frequent peripheral aneurysm, predominantly affects men over 60 years of age and has a high morbidity associated to his complications, among which are ischemic complication, which can often end in amputation of the limb. Less frequent complications such as neuropathic and venous complications, particularly deep vein thrombosis, are equally relevant. Case presentation: Patient with an aneurysm of the popliteal artery complicated by thrombosis of the adjacent popliteal vein. Color Doppler ultrasound plays a fundamental role in the diagnosis.

Abstract Intravascular histiocytosis is a rare condition characterized by the aggregate of histiocytes within dilated dermal vessels. The diagnosis is mainly histophatological and immunohistochemical. We describe a case of a 55 year-old female patient presenting erythematous/purple patches on the breasts, back and limbs. She previously presented ductal carcinoma in the right breast in 2006 which was treated with mastectomy and proceeded to silicone breast implant in 2009. Clinical hypothesis was telangiectatic metastatic carcinoma. Histopathology showed vascular ectasia, thrombosis and recanalization of upper dermis small vessels. On immunohistochemistry, intravascular cells were CD 68+ and negative for estrogen and progesterone receptors, CK7, EMA and AE1/AE3 and endothelial cells were CD64+, leading to the diagnosis of intravascular histiocytosis.

RESUMO A trombose portomesentérica (TPM) é uma complicação potencialmente grave que pode ocorrer após a cirurgia bariátrica. A TPM ganhou importância devido ao crescente número de cirurgias bariátricas sendo realizadas. Objetivo: Relatar complicação rara após cirurgia bariátrica, porém grave e de difícil manejo. Tentar identificar algumas características comuns aos pacientes e discutir possíveis causas, comparando a pouca literatura disponível. Métodos: Descrevemos seis casos de TPM em mulheres jovens com diferentes apresentações. Resultados: Todos os seis casos ocorreram em mulheres jovens de 29 a 41 anos sem obesidade grave - índice de massa corporal - IMC: 36 a 39 e com peso que variou de 105 a 121 kg. As pacientes apresentavam poucas comorbidades (todas relacionadas à síndrome metabólica) e esteatose hepática moderada, sem sinais de cirrose. Cinco pacientes usavam contraceptivos orais até dias antes da cirurgia. Uma paciente apresentou resultado positivo para trombofilia. Cinco pacientes foram submetidas a gastrectomia vertical e apenas uma submetida ao bypass gástrico sem complicações durante a cirurgia (tempo médio de operação: 61,3 min, variando de 52 a 91 min). A duração média do seguimento após a hospitalização foi de 12,3 meses (variação: 7 a 18 meses) e até o momento apenas uma paciente não teve recanalização. Conclusão: A frequência da TPM parece ser maior em mulheres e após gastrectomia vertical. Nossos achados indicam que pacientes com dor abdominal semanas após a cirurgia bariátrica devem ser investigados.

ABSTRACT Portomesenteric vein thrombosis (PMVT) is a potentially severe complication that can occur after bariatric surgery. PMVT has gained importance because of the increasing number of bariatric surgeries being performed. Objective: to report a rare and severe complication after bariatric surgery, which is difficult to manage. To try to identify common characteristics among the cases and discuss potential causes comparing our data to the available literature. Methods: We describe six cases of PMVT in young women with different presentations. Results: All six cases occurred in young women 29-41 years old with obesity - body mass index - BMI: 36-39) and weighing 105-121 kg. The patients had few comorbidities (all of which were related to metabolic syndrome) and moderate hepatic steatosis with no sign of cirrhosis. Five patients used oral contraceptives until a few days before the operation. One patient tested positive for thrombophilia. Five patients underwent a laparoscopic sleeve gastrectomy and one underwent a gastric bypass with no complications during the operation (median operating time: 61.3 min, range 52-91 min). The mean duration of follow-up after hospitalization was 12.3 months (range: 7-18 months) and to-date only one patient has had no recanalization. Conclusion: The frequency of PMVT appears to be increased in woman and after sleeve gastrectomy. Our findings indicate that patients with abdominal pain weeks after bariatric surgery must be investigated.

SUMMARY A background of Pulmonary Hypertension (PH) indicates a progressive elevation of pulmonary vascular resistance, leading to overfilling, elevation of venous pressure, congestion in various organs, and edema in the venous system. This study aimed to investigate whether PH is a risk factor for deep vein thrombosis (DVT) of the lower extremities after hip and knee replacement surgery. METHODS A total of 238 patients who received joint replacement of lower extremities in our department of orthopedics from January 2009 to January 2012 were examined by echocardiography and Color Doppler flow imaging (CDFI) of the lower extremities. Based on pulmonary artery pressure (PAP), the patients were divided into a normal PAP group (n=214) and PH group (n=24). All the patients were re-examined by CDFI during post-operative care. RESULTS Among the 238 patients, 18 had DVT in the lower extremities after the operation. DVT total incidence rate was 7.56% (18/238). In the PH group, 11 patients had DVT (45.83%, 11/24), but in the normal PAP group, only 7 had DVT (3.27%, 7/214). The incidence of DVT was significantly lower in the normal PAP group than in the PH group (P<0.01). In addition, there was a positive correlation between PAP and the incidence of DVT. CONCLUSION PH could be a high-risk factor for the occurrence of DVT in patient's lower extremities after joint replacement surgeries.

RESUMO OBJETIVO A hipertensão pulmonar (HP) indica elevação progressiva da resistência vascular pulmonar, levando ao excesso de enchimento, elevação da pressão venosa, congestão em vários órgãos e edema no sistema venoso. Este estudo teve como objetivo investigar se a HP é um fator de risco para trombose venosa profunda (TVP) das extremidades inferiores após cirurgia de prótese de quadril e joelho. MÉTODOS Um total de 238 pacientes que receberam a substituição da articulação das extremidades inferiores em nosso departamento de ortopedia de janeiro de 2009 a junho de 2012 foi examinado por ecocardiograma e fluxo de imagem Doppler colorido (CDFI) dos membros inferiores. De acordo com a pressão arterial pulmonar (PAP), os pacientes foram divididos em grupo PAP normal (n=214) e grupo PH (n=24). Todos os pacientes foram reexaminados por CDFI durante os cuidados pós-operatórios. RESULTADOS Entre os 238 pacientes, 18 pacientes tiveram TVP nas extremidades inferiores após a operação. A taxa de incidência total de TVP foi de 7,56% (18/238). No grupo PH, 11 pacientes tiveram TVP (45,83%, 11/24), mas no grupo PAP normal, apenas sete pacientes tiveram TVP (3,27%, 7/214). A incidência de TVP foi significativamente menor no grupo PAP normal do que no grupo PH (P<0,01). Além disso, houve uma correlação positiva entre a PAP e a incidência de TVP. CONCLUSÃO A HP poderia ser um fator de alto risco para a ocorrência de TVP nas extremidades inferiores do paciente após cirurgias de substituição articular.

Introduction:La thrombose veineuse cérébrale représente une pathologie vasculaire veineuse autrefois dite rare. Objectif:L'objectif principal de notre étude était d'étudier les différents aspects cliniques, paracliniques, étiologiques et évolutifs des thromboses veineuses cérébrales. Méthodologie:Il s'agissait d'une étude prospective de 30 cas de thromboses veineuses cérébrales admis au service deneurologie de Fann durant la période allant de janvier 2013 à juillet 2016. L'imagerie cérébrale était le critèreindispensable pour confirmer le diagnostic.Résultats:Notre enquête comportait 21 femmes et 9 hommes avec un âge moyen de 34,4 ans. L'installation des signes était subaigüe dans la majorité des cas. Le motif d'admission était polymorphe, dominé par les céphalées(86,7%), les vomissements (60,0%), l'hémiplégie (56,7%). L'imagerie cérébrale révélait majoritairement 14 cas de thrombose du sinus latéral (46,7 %) et 10 cas de sinus longitudinal supérieur (33,3%). Les causes non infectieuses (50%) notamment gynéco-obstétricales dominaient. L'évolution sous héparinothérapie était le plus souvent favorable ; seules des céphalées séquellaires demeuraient. Conclusion La thrombophlébite cérébrale constitue une urgence pronostique et thérapeutique. La variabilité du diagnostic pourrait expliquer le retard de la prise en charge

Abstract Introduction: Advanced hepatic disease may - in addition to the widely recognized hemorrhagic complications - occur with thrombotic events. We describe the case of a cirrhotic patient taking warfarin and whose coagulation management during liver transplantation was guided by thromboelastometry (ROTEM®). Case report: A 56 year-old male patient diagnosed with alcohol cirrhosis using warfarin (2.5−1) for partial portal vein thrombosis with the International Normalized Ratio (INR) of 2.14. At the beginning of surgery, the ROTEM® parameters were all normal. In the anhepatic phase, EXTEM and INTEM remained normal, but FIBTEM showed reduction of amplitude after 10 min and maximum clot firmness. Finally, in the neohepatic phase, there was a slight alteration in the hypocoagulability of most of the parameters of the EXTEM, INTEM and FIBTEM, besides a notable correction of the Coagulation Time (CT) in HEPTEM compared to the CT of the INTEM. Therefore, the patient did not receive any transfusion of blood products during surgery and in the postoperative period, being discharged on the 8th postoperative day. Discussion: Coagulation deficit resulting from cirrhosis distorts INR as a parameter of anticoagulation adequacy and as a determinant of the need for blood transfusion. Thus, thromboelastometry can provide important information for patient management.

Resumo Introdução: A doença hepática avançada pode, além das complicações hemorrágicas amplamente reconhecidas, ocorrer com eventos trombóticos. Descrevemos o caso de um paciente cirrótico em uso de varfarina, cujo manejo da coagulação durante o transplante de fígado foi guiado por tromboelastometria (ROTEM®). Relato de caso: Paciente do sexo masculino, 56 anos, diagnosticado com cirrose alcoólica, recebendo varfarina (2,5 mg.dia−1) para trombose parcial da veia porta, com razão normalizada internacional (INR) de 2,14. No início da cirurgia, os parâmetros ROTEM® estavam todos normais. Na fase não hepática, EXTEM e INTEM permaneceram normais, mas FIBTEM mostrou redução da amplitude após 10 min e firmeza máxima do coágulo. Por fim, na fase neo-hepática houve uma ligeira alteração da hipocoagulabilidade na maioria dos parâmetros de EXTEM, INTEM e FIBTEM, além de uma correção notável do tempo de coagulação (CT) de HEPTEM em comparação com o CT de INTEM. Portanto, o paciente não recebeu transfusão de hemoderivados durante a cirurgia e no período pós-operatório, obteve alta no oitavo dia de pós-operatório. Discussão: O déficit de coagulação resultante da cirrose distorce o INR como um parâmetro da adequação da anticoagulação e como um determinante da necessidade de transfusão de sangue. Portanto, a tromboelastometria pode fornecer informações importantes para o manejo do paciente.

La relación existente entre trombosis y cáncer es ampliamente conocida. Sin embargo, este vínculo es frecuentemente subestimado en las neoplasias hematológicas, hecho que debe mantener alerta al médico clínico. La trombosis venosa profunda puede constituir la manifestación inicial de una leucemia aguda o precederla en el diagnóstico. La búsqueda minuciosa de esplenomegalia y linfadenopatías en el examen clínico, así como una mirada atenta al recuento completo de células sanguíneas (hemograma completo) son esenciales para no omitir el diagnóstico, con implicancias pronósticas y terapéuticas directas. Se presenta el caso clínico de una paciente con trombosis venosa profunda en el miembro inferior izquierdo como debut de una leucemia aguda.

The relationship between thrombosis and cáncer is widely knkown. However, this relationship is often underestimated in hematologic neoplasms, what needs to be borne in mind my clinicians. Deep vein thrombosis (DVT) may constitute the initial manifestation of acute leukemia or precede its diagnosis. The meticulous search for splenomegaly and lymphadenopathies in the clinical examination, as well as the careful analysis of complete blood count are crucial for diagnostic purposes, and has direct prognostic and therapeutic implications. The study presents the clinical case of a patient with deep vein thrombosis in the left lower limb as a debut of acute leukemia.

La tuberculose est un facteur de risque de maladies thromboemboliques. Nous rapportons le cas d'une fille de dix ans qui a présenté un premier épisode de thrombose veineuse profonde découverte devant une douleur du membre pelvien droit avec œdème et impotence fonctionnelle, confirmée par un échodoppler des vaisseaux de la cuisse. Lors de la recherche de la cause, la tuberculose pulmonaire a été diagnostiquée selon les critères de l'Union Internationale Contre la Tuberculose et les Maladies Respiratoires. La patiente a été mise sous des antituberculeux associés à l'héparine de bas poids moléculaire relayée par l'anti vitamine K. L'évolution a été favorable. Il conviendrait en l'absence de diagnostic microbiologique de la tuberculose dans les pays à ressources limitées, d'évoquer une tuberculose devant toute thrombose veineuse profonde associée à une pneumonie

ABSTRACT Renal vein thrombosis (RVT) is a complication often associated with nephrotic syndrome. It occurs due to a state of hypercoagulability common in the diseases that attend to this syndromic diagnosis. It should be suspected whenever there is nephrotic syndrome associated with sudden flank pain, hematuria and worsening of proteinuria. Bilateral RVT also presents with frequently oliguric renal dysfunction. This case reports a 33-year-old patient hospitalized for a nephrotic syndrome, with etiologic investigation suggestive of primary membranous glomerulopathy, which evolved with bilateral RVT associated with deterioration of renal function and need for renal replacement therapy. He promptly performed angiography with thrombectomy and thrombolysis, evolving with recovery of renal function in two weeks.

RESUMO A trombose de veia renal (TVR) é uma complicação muitas vezes associada à síndrome nefrótica. Ocorre devido a um estado de hipercoagulabilidade comum nas enfermidades que cursam com esse diagnóstico sindrômico. Deve ser suspeitada sempre que houver síndrome nefrótica associada à dor súbita em flanco, hematúria e piora da proteinúria. TVR bilateral cursa, ainda, com disfunção renal frequentemente oligúrica. Esse caso reporta um paciente de 33 anos internado por um quadro de síndrome nefrótica, com investigação etiológica sugestiva de glomerulopatia membranosa primária, que evoluiu com TVR bilateral associada à deterioração da função renal e necessidade de terapia substitutiva renal. Realizou, prontamente, angiografia com trombectomia e trombólise, evoluindo com recuperação da função renal em duas semanas.

Se presentan 3 casos de trombosis de la vena ovárica, uno en relación a cirugía pélvica y dos durante el postparto. La trombosis de la vena ovárica es una complicación rara, de presentación clínica inespecífica, lo que hace plantearse un diagnóstico diferencial con otras patologías más frecuentes (apendicitis, pielonefritis, etc), siendo la TAC el gold standard para su diagnóstico. El tratamiento más adecuado son los anticoagulantes.

We report 3 cases of varian vein thrombosis, one in relation with pelvic surgery and 2 during the postpartum period. The ovarian vein thrombosis is a rare complication, with inespecific symptoms, that is why it is obligatory to propose a differential diagnosis with more frecuent patologies (appendicitis, pyelonephritis, etc.), the CAT is the gold standard in its diagnosis. Anticoagulants are the most suitable treatment.

Heparin-induced thrombocytopenia (HIT) is immune-mediated. It occurs more frequently with unfractionated heparin (UFH) than with low molecular weight heparins (LMWH). It is associated with thromboembolic rather than hemorrhagic events, as opposed to thrombocytopenia of other etiologies. The key in therapy is the cessation of heparin and the start of another anticoagulant. We report a 58 years old female with HIT secondary to the use of Enoxaparin who was successfully managed with Rivaroxaban. Our goal is to report a novel therapy and provide the evidence that supports its use.

Abstract Introduction Cerebral venous thrombosis (CVT) is a rare but serious complication after spinal anesthesia. It is often related to the presence of predisposing factors, such as pregnancy, puerperium, oral contraceptive use, and malignancies. Headache is the most common symptom. We describe a case of a patient who underwent spinal anesthesia and had postoperative headache complicated with CVT. Case report Male patient, 30 years old, ASA 1, who underwent uneventful arthroscopic knee surgery under spinal anesthesia. Forty-eight hours after the procedure, the patient showed frontal, orthostatic headache that improved when positioned supine. Diagnosis of sinusitis was made in the general emergency room, and he received symptomatic medication. In subsequent days, the headache worsened with holocranial location and with little improvement in the supine position. The patient presented with left hemiplegia followed by tonic-clonic seizures. He underwent magnetic resonance venography; diagnosed with CVT. Analysis of procoagulant factors identified the presence of lupus anticoagulant antibody. The patient received anticonvulsants and anticoagulants and was discharged on the eighth day without sequelae. Discussion Any patient presenting with postural headache after spinal anesthesia, which intensifies after a plateau, loses its orthostatic characteristic or become too long, should undergo imaging tests to rule out more serious complications, such as CVT. The loss of cerebrospinal fluid leads to dilation and venous stasis that, coupled with the traction caused by the upright position, can lead to CVT in some patients with prothrombotic conditions.

Resumo Introdução: A trombose venosa cerebral (TVC) é uma complicação rara, mas grave, após raquianestesia. Está frequentemente relacionada com a presença de fatores predisponentes, como gestação, puerpério, uso de contraceptivos orais e doenças malignas. O sintoma mais frequente é a cefaleia. Descrevemos um caso de um paciente submetido à raquianestesia que apresentou cefaleia no período pós-operatório complicada com TVC. Relato de caso: Paciente de 30 anos, ASA 1, submetido à cirurgia de artroscopia de joelho sob raquianestesia, sem intercorrências. Quarenta e oito horas após o procedimento apresentou cefaleia frontal, ortostática, que melhorava com o decúbito. Foi feito diagnóstico de sinusite em pronto socorro geral e recebeu medicação sintomática. Nos dias subsequentes teve pioria da cefaleia, que passou a ter localização holocraniana e mais intensa e com pequena melhora com o decúbito dorsal. Evoluiu com hemiplegia esquerda seguida de convulsões tônico-clônicas generalizadas. Foi submetido à ressonância magnética com venografia que fez o diagnóstico de TVC. A pesquisa para fatores pró-coagulantes identificou a presença de anticorpo lúpico. Recebeu como medicamentos anticonvulsivantes e anticoagulantes e teve alta hospitalar em oito dias, sem sequelas. Discussão: Qualquer paciente que apresente cefaleia postural após uma raquianestesia, e que intensifica após um platô, perca sua característica ortostática ou se torne muito prolongada, deve ser submetido a exames de imagem para excluir complicações mais sérias como a TVC. A perda de líquido cefalorraquidiano leva à dilatação e à estase venosa, que, associadas à tração provocada pela posição ereta, podem, em alguns pacientes com estados protrombóticos, levar à TVC.
