Objective: To study the clinico-hematological profile, complications, and management of children with non-transfusion dependent thalassemia (NTDT) in northern India. Method: We retrieved and analyzed the data of 69 children with NTDT diagnosed between January, 2006 to December, 2018, aged under 18 years from our unit’s records. Result: The participants mean (SD) age was 4.4 (3.1) years, and they presented with anemia (29%), jaundice (13%), hemolytic facies (13%), splenomegaly (87%), thromboembolism (2.9%) and pathological short stature (28.5%). The most common cause of NTDT was ?-thalassemia (45%), followed by either compound-heterozygous or homozygous for E?-thalassemia mutation. The most frequent single genotype observed was compound heterozygous for IVS1-5 (G>C) and codon 26 (G>A). The mean (SD) follow-up duration was 3.5 (2.4) years. On follow-up, 27 children (%) remained transfusion free, and 30 (%) needed occasional transfusions. 63% of patients initially presenting with pathological short stature showed improvement in growth. Amongst children older than 10 years (n=20), subclinical hypothyroidism was detected in 6 children and impaired glucose tolerance test in 1 child. Conclusion: Eß-thalassemia was the commonest cause of NTDT in this population.

Venous thromboembolism (VTE) in pregnancy and resulting thrombotic disorders are increasingly being recognized as an important cause of maternal morbidity and mortality. The diagnosis of VTE during pregnancy has an impact on current as well as future foeto-maternal outcomes. Whereas algorithms to manage VTEs during pregnancy in developed countries exist, these are difficult to implement in resource-constraint settings. In this narrative review, we discuss strategies that can be applied in daily clinical practice by obstetricians and haematologists dealing with these disorders in the country

CVST often creates challenges regarding diagnosis among physicians, due to the nonspeci?c symptoms and countless presentation and absence of uniform symptoms. This study aims to understand current knowledge about CSVT including its pathogenesis, etiogenesis, clinical profile, diagnosis, and treatment. A Methods: descriptive cross-sectional study was conducted in the department of neurology at tertiary care hospital, Mumbai between January, 2021 and June 2022. This study was approved by institutional ethics committee. All patients who were more than 18 years with diagnosis of cerebral venous sinus thrombosis, admitted to critical care unit of neurology department were included in this study and those with bleeding disorder and prior anticoagulation therapy, already diagnosed with CVST were excluded. CVST was 3 times more common in females than in m Results: ales and the age group of 21 to 30 years was more common affected. Headache was the most common symptom seen and papilledema was the most common sign. In females puerperium was the main cause of CVST. Superior sagittal sinus and right transverse sinus were the most common sinuses involved as seen on Computed tomography(CT)venography/Magnetic resonance venography(MRV)and common finding was venous infarct. The mortality rate was 16%. Patients with Isolated intracranial hypertension syndrome(ICH) had good outcome. Variables like age ?35 years, GCS score of <8 and coma at presentation were associated with poor prognosis. CVST has a wide range of cli Conclusion nical presentation. The prognosis is good in CVST but early diagnosis with treatment and care is required in patients with poor prognostic factors.

Resumen Antecedentes: El reemplazo valvular por prótesis mecánicas o biológicas implica riesgo de tromboembolismo y complicaciones hemorrágicas. Objetivo: Determinar las complicaciones relacionadas con la terapia de anticoagulación complementaria y la probabilidad de riesgo en pacientes portadores de prótesis valvulares del corazón. Métodos: Se estudiaron 163 pacientes entre 2002 y 2016, portadores de prótesis mecánicas y biológicas, quienes recibieron antagonistas de la vitamina K posterior al egreso hospitalario. La terapia de anticoagulación se categorizó en óptima y no óptima conforme a los valores de INR previos a las complicaciones. Fueron excluidos los pacientes con comorbilidades y otros factores de riesgo de trombosis y/o sangrado. Resultados: a 68.7 % de los pacientes se les colocó prótesis mecánica y a 31.3 %, biológica (p ≤ 0.001); 25.2 % presentó las complicaciones motivo de estudio (p ≤ 0.001), hemorrágicas en 48.8 %, tromboembólicas en 26.8 % y de ambos tipos en 24.4 % (riesgo relativo = 4.229); a 95.1 % de los pacientes con complicaciones se les colocó prótesis mecánica y a 4.9 %, biológica (p = 0.005); 49.7 % presentó INR no óptimo (p ≤ 0.001). Conclusiones: Ante riesgo alto de complicaciones tromboembólicas y hemorrágicas, la elección de las prótesis valvulares, la prevención y el seguimiento son prioridades, principalmente en quienes requieren terapia de anticoagulación.

Abstract Background: Heart valve replacement surgery with mechanical or biological prostheses entails a risk of thromboembolism and bleeding complications. Objective: To determine the complications related to complementary anticoagulation therapy and the probability of risk. Methods: One-hundred and sixty-three patients who underwent heart valve replacement between 2002 and 2016 with either mechanical or biological prostheses, and who received vitamin K antagonists after hospital discharge, were studied. Anticoagulation therapy was categorized into optimal and non-optimal according to INR values prior to the development of complications. Patients with comorbidities and other risk factors for thrombosis and/or bleeding were excluded. Results: In total, 68.7 % of patients received mechanical prostheses, and 31.3 %, biological prostheses (p ≤ 0.001); 25.2 % experienced the complications that motivated the study (p ≤ 0.001), which were hemorrhagic in 48.8 %, thromboembolic in 26.8 %, and of both types in 24.4 % (relative risk = 4.229). Among the patients with complications, 95.1 % received mechanical prostheses, and 4.9 %, biological (p = 0.005); non-optimal INR was identified in 49.7 % (p ≤ 0.001). Conclusions: Given the high risk of thromboembolic and hemorrhagic complications, valve prostheses must be carefully chosen, and care priorities should include prevention and follow-up, especially in those patients who require anticoagulation therapy.

Introducción. El bazo es un órgano linfoide implicado en el reconocimiento antigénico, la depuración de patógenos y la remoción de eritrocitos envejecidos o con inclusiones citoplasmáticas. La esplenectomía es una técnica utilizada tanto para el diagnóstico (linfomas), el tratamiento (trombocitopenia inmune, anemia hemolítica adquirida) y la curación (microesferocitosis hereditaria) de diversas enfermedades. Métodos. Describir los principales cambios hematológicos y complicaciones asociadas al procedimiento de esplenectomía. Discusión. Los cambios posteriores a la esplenectomía pueden ser inmediatos, como la aparición de cuerpos de Howell-Jolly, la trombocitosis y la presencia de leucocitosis durante las primeras dos semanas. Otras complicaciones tempranas incluyen la presencia de trombosis, en especial en pacientes con factores de riesgo secundarios (edad, sedentarismo, manejo hospitalario, obesidad) o un estado hipercoagulable (diabetes, cáncer, trombofilia primaria), siendo tanto el flujo de la vena porta como el volumen esplénico los principales factores de riesgo para su aparición. Las complicaciones tardías incluyen la alteración en la respuesta inmune, aumentando el riesgo de infecciones por bacterias encapsuladas, en conjunto con una reducción en los niveles de IgM secundario a la ausencia de linfocitos B a nivel de bazo. Debido al riesgo de infecciones, principalmente por Streptococcus pneumoniae, la esplenectomía parcial se ha considerado una opción. Conclusión. Una adecuada valoración de la indicación de esplenectomía y la identificación precoz de complicaciones posoperatorias son fundamentales para reducir la mortalidad asociada a la esplenectomía

Introduction. The spleen is a lymphoid organ involved in antigen recognition, pathogen clearance, and removal of aged erythrocytes or those with cytoplasmic inclusions. Splenectomy is a technique used for diagnosis (lymphomas), treatment (immune thrombocytopenia, acquired hemolytic anemia), and cure (hereditary microspherocytosis) of various diseases. Methods. To describe the main hematological changes and complications associated with the splenectomy procedure. Discussion. Changes after splenectomy can be considered immediate: the appearance of Howell-Jolly bodies, thrombocytosis, and leukocytosis during the first two weeks. Other complications include the presence of thrombosis, especially in patients with risk factors (age, sedentary lifestyle, long hospital stay, obesity) or a hypercoagulable state (diabetes, cancer, primary thrombophilia), with both portal vein flow and splenic volume being the main risk factors for its appearance. Late complications include altered immune response, increased risk of infections by encapsulated bacteria, and a reduction in IgM levels secondary to the absence of B lymphocytes in the spleen; due to the risk of diseases mainly by Streptococcus pneumoniae, partial splenectomy has been considered an option. Conclusion. An adequate assessment of the indication for splenectomy and the early identification of complications are essential to reduce the mortality associated with splenectomy

Intracardiac masses have several etiologies: tumor, infectious, thrombotic. They constitute a diagnostic challenge for the clinician. Behçet's disease is a chronic multisystemic vasculitis evolving by relapses. Intracadiac thrombosis in this disease deserves special attention because of its life-threatening nature. They often appear in the early stages of the disease, and the most frequent location is the right heart chambers. We present the case of a 23-year-old patient with an isolated mass in the right ventricle revealing an initial manifestation of Behçet's disease. The presented clinical case highlights the importance of early recognition of Behçet's disease, as well as the awareness of including this disease in the differential diagnosis of intracardiac masses in young adults.

Abstract Background Cerebral venous sinus thrombosis (CVST) is not as well understood as an ischemic stroke of arterial origin. Although the prognosis of CVST is usually good, parenchymal lesions may occur in some patients, and the development of intracranial herniation may result in death. For this reason, recognizing the risk factors for intracranial herniation and accurately determining those patients who should undergo decompressive craniectomy is important. Objective This study aims to determine the risk factors for intracranial herniation in patients with CVST. Methods A total of 177 patients diagnosed with CVST between 2015 and 2021 in our tertiary center were retrospectively included in this study. Results Of the 177 patients, 124 were female and 53 were male with mean ages of 40.65 ± 13.23 and 44.13 ± 17.09, respectively. Among those, 18 patients had developed intracranial herniation. A significant statistical relationship was observed between superior sagittal sinus thrombosis, sinus rectus thrombosis, venous collateral score, nonhemorrhagic venous infarct, presence of malignancy, small juxtacortical hemorrhage, and cortical vein thrombosis. The binary logistic regression analysis results showed that the most significant variables were the venous collateral score of 0, malignancy, and small juxtacortical hemorrhages. Conclusion This study identified small juxtacortical hemorrhages, the presence of malignancy, and a venous collateral score of 0 to be independent risk factors for intracranial herniation in CVST patients. Drawing on these results, we recommend close clinical observation of CVST patients, as they may be candidates for decompressive craniectomy.

Resumo Antecedentes A trombose do seio venoso cerebral (CVST) não é tão bem compreendida como um acidente vascular cerebral isquémico de origem arterial. Embora o prognóstico de CVST seja geralmente bom lesões parenquimatosas podem ocorrer em alguns pacientes e o desenvolvimento de herniação intracraniana pode resultar em morte. Por esse motivo é importante reconhecer os fatores de risco para hérnia intracraniana e determinar com precisão os pacientes que devem ser submetidos à craniectomia descompressiva. Objetivo Este estudo tem como objetivo determinar os fatores de risco para herniação intracraniana em pacientes com CVST. Métodos Um total de 177 pacientes diagnosticados com CVST entre 2015 e 2021 em nosso centro terciário foram retrospectivamente incluídos neste estudo. Resultados Dos 177 pacientes 124 eram do sexo feminino e 53 do masculino com média de idade de 40 65 ± 13 23 e 44 13 ± 17 09 respectivamente. Destes 18 pacientes desenvolveram hérnia intracraniana. Uma relação estatística significativa foi observada entre trombose do seio sagital superior trombose do seio reto escore de colateral venosa infarto venoso não hemorrágico presença de malignidade pequena hemorragia justacortical e trombose da veia cortical. Os resultados da análise de regressão logística binária mostraram que as variáveis mais significativas foram o escore colateral venoso de 0 malignidade e pequenas hemorragias justacorticais. Conclusão Este estudo identificou pequenas hemorragias justacorticais a presença de malignidade e um escore colateral venoso de 0 como fatores de risco independentes para herniação intracraniana em pacientes CVST. Com base nesses resultados recomendamos uma observação clínica rigorosa dos pacientes CVST pois eles podem ser candidatos à craniectomia descompressiva.

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

A hipoplasia da veia cava inferior é uma patologia rara que integra o conjunto de anomalias do desenvolvimento da veia cava inferior. A sua incidência situa-se entre 0,3%-0,5% na população saudável e 5% nos adultos jovens sem fatores de risco para trombose venosa profunda, sendo considerada um importante fator de risco para o desenvolvimento de trombose dos membros inferiores. O principal objetivo deste trabalho é reportar a conduta obstétrica de um caso clínico de uma grávida diagnosticada com hipoplasia da veia cava inferior, prévia à gravidez. Trata-se de um caso clínico, de uma grávida, primigesta, com 37 anos, com hipoplasia da veia cava inferior e heterozigotia para o gene MTHFR677 diagnosticadas, na sequência de uma trombose venosa bilateral dos membros inferiores e do segmento infrarrenal da veia cava inferior. A gravidez foi seguida em consulta hospitalar na nossa instituição, tendo a grávida sido medicada com enoxaparina em dose profilática e ácido acetilsalicílico, com um período pré natal que decorreu sem intercorrências. Às 37 semanas e 6 dias de gestação, deu entrada no Serviço de Urgência de Obstetrícia por rotura prematura de membranas. Intraparto foram utilizadas meias de compressão pneumática intermitente, tendo o parto ocorrido às 38 semanas de gestação por via vaginal (parto eutócico), do qual nasceu um recém-nascido do sexo feminino, com 2620g e índice de Apgar 9/10/10. O presente caso clínico demonstra que em situações de hipoplasia da veia cava inferior com um seguimento obstétrico adequado é possível a realização de um parto vaginal, possibilitando um desfecho obstétrico favorável (AU).

Hypoplasia of the inferior vena cava is a rare condition that belongs to the group of developmental anomalies of the inferior vena cava. It has an incidence between 0.3% and 0.5% in the healthy population and 5% in young adults without risk factors for deep venous thrombosis, being considered an important risk factor for the development of lower limb thrombosis. This study aims to report the obstetric conduct of a clinical case of a pregnant woman diagnosed with hypoplasia of the inferior vena cava prior to pregnancy. This is a clinical case of a pregnant woman, primigravid 37 years old, with hypoplasia of the inferior vena cava and heterozygosity for MTHFR677, diagnosed following a bilateral venous thrombosis of the lower limbs and the infrarenal segment of the inferior vena cava. The pregnancy was followed up in our institution. The pregnant woman was medicated with a prophylatic dose of low molecular weight heparin and acetylsalicylic acid with an uneventful prenatal period. At 37 weeks and 6 days of gestation, she was admitted to the Obstetrics Emergency Service due to premature rupture of membranes. Intermittent pneumatic compression sockings were used intrapartum, and at 38 weeks of gestation, a female newborn was vaginally delivered (eutocic delivery) with 2620g and an Apgar score of 9/10/10. The present clinical case demonstrates that in situations of hypoplasia of the inferior vena cava with an adequate obstetric follow-up, it is possible to perform a vaginal delivery, enabling a favourable obstetric outcome (AU).

Abstract Carpal tunnel syndrome is the most common compressive neuropathy of the upper limb, affecting ~ 4% of the general population. The clinical picture is characterized by pain and, mainly, paresthesia in the median nerve territory, of insidious onset and, in the most severe cases, loss of strength and atrophy of the thenar musculature is observed. It is an extremely common pathology in the daily practice of hand surgery, and in most cases, it can be treated with conservative methods. We present here an atypical case of carpal tunnel syndrome, of acute onset, triggered by persistent median artery (PMA) thrombosis, condition associated with distal embolization and hypoper-fusion of the limb.

Resumo A síndrome do túnel do carpo é a neuropatia compressiva mais comum do membro superior, afetando ~ 4% da população geral. O quadro clínico caracteriza-se por dor e, principalmente, parestesia no território do nervo mediano, de início insidioso e, nos casos mais graves, observa-se perda de força e atrofia da musculatura tenar. Trata-se de patologia extremamente comum na prática diária de cirurgia da mão, e na maior parte dos casos pode ser tratada com métodos conservadores. Apresentamos aqui um caso atípico de síndrome do túnel do carpo, de surgimento agudo, desencadeado pela trombose da artéria mediana persistente, quadro associado com embolização distal e hipoperfusão do membro.

The trigeminal nerve is the fifth cranial nerve, which transmits facial sensations, and is divided into the ophthalmic, maxillary, and mandibular branches. Damage to this nerve can cause trigeminal neuralgia, a clinical condition that can also present in patients with coronavirus disease 2019 (COVID-19). This meta-analysis reviews the clinical cases of trigeminal neuralgia reported in patients with COVID-19 from 2019 to 2022, describes the anatomical mechanism of pain and its radiation and identifies other associated symptoms. We performed a literature search to identify reports of patients with COVID-19 who developed trigeminal neuralgia and examined these cases for prevalence and any identified source of associated ocular pain. Of the relevant studies identified, 638 patients with COVID-19 developed trigeminal neuralgia out of 7561 total COVID-19 cases (8.4 %). Of the 638 cases, 590 (7.8 %) had known causes of ocular pain, while the cause of ocular pain was unknown in 48 cases (0.6 %). Trigeminal neuralgia developed infrequently in patients with COVID-19, and cases with known causes of ocular pain were more common than cases with unknown causes. Understanding the link between COVID-19 and trigeminal neuralgia may lead to preventing further complications and mortality in these patients, as well as improving care for patients with these conditions in the future. Additionally, understanding these new clinical issues can prepare many types of physicians to protect themselves better in the event of a COVID-19 outbreak among medical staff in different departments of hospitals, such as clinics, wards, emergency rooms, and operating theatres.

El nervio trigémino es el quinto par craneal, que transmite las sensaciones faciales, y se divide en las ramas oftálmica, maxilar y mandibular. El daño a este nervio puede causar neuralgia del trigémino, una condición clínica que también puede presentarse en pacientes con enfermedad por coronavirus 2019 (COVID-19). Este metaanálisis revisa los casos clínicos de neuralgia del trigémino informados en pacientes con COVID-19 desde 2019 hasta 2022, describe el mecanismo anatómico del dolor y su radiación e identifica otros síntomas asociados. Realizamos una búsqueda bibliográfica para identificar informes de pacientes con COVID-19 que desarrollaron neuralgia del trigémino y examinamos estos casos en busca de prevalencia y cualquier fuente identificada de dolor ocular asociado. De los estudios relevantes identificados, 638 pacientes con COVID-19 desarrollaron neuralgia del trigémino de un total de 7561 casos de COVID-19 (8,4 %). De los 638 casos, 590 (7,8 %) tenían causas conocidas de dolor ocular, mientras que la causa del dolor ocular era desconocida en 48 casos (0,6 %). La neuralgia del trigémino se desarrolló con poca frecuencia en pacientes con COVID-19, y los casos con causas conocidas de dolor ocular fueron más comunes que los casos con causas desconocidas. Comprender el vínculo entre COVID-19 y la neuralgia del trigémino puede ayudar a prevenir más complicaciones y mortalidad en estos pacientes, así como a mejorar la atención de los pacientes con estas afecciones en el futuro. Además, comprender estos nuevos problemas clínicos puede preparar a muchos tipos de médicos para protegerse mejor en caso de un brote de COVID-19 entre el personal médico en diferentes departamentos de hospitales, como clínicas, salas de emergencia y quirófanos.

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.

RESUMEN INTRODUCCIÓN: La COVID-19 se acompaña de eventos tromboembólicos venosos y arteriales en pacientes con historia de hipertensión y aterosclerosis. Se reporta el caso de una paciente joven y sin factores de riesgo cardiovascular que adquirió la infección por el SARS-COV2 y luego presentó un accidente cerebrovascular isquémico. CASO: Paciente de 44 años hospitalizada por la covid-19 en tratamiento protocolario con anticoagulación, esteroide y oxígeno suplementario. Al día 7 del inicio de los síntomas respiratorios presentó infarto cerebral por trombosis de arteria carótida derecha, arteria cerebral media derecha e izquierda y edema cerebral hemisférico derecho, tras lo cual fue diagnosticada con muerte encefálica. El estudio vascular no documentó una etiología diferente a la covid-19. DISCUSIÓN: Se plantea que la infección condiciona un estado inflamatorio sistémico, endotelialitis, ulceración de placas ateroscleróticas preexistentes e hipercoagulabilidad. Lo anterior facilita la aparición de trombosis vascular. Es frecuente encontrar elevación de reactantes de fase aguda y de los productos del metabolismo de la fibrina. El accidente cerebrovascular (ACV) isquémico se ha descrito en el 1 al 5 % de los pacientes con la covid-19. En pacientes con factores de riesgo cardiovascular, durante las primeras 2 semanas desde el inicio de los síntomas respiratorios, el compromiso isquémico suele afectar a múltiples territorios vasculares. CONCLUSIÓN: La covid-19 por sí sola es un factor de riesgo para trombosis arterial secundaria a la inflamación sistémica y estados de hipercoagulabilidad, por lo que debe ser tenida en cuenta en el estudio de ACV isquémico en pacientes jóvenes.

ABSTRACT INTRODUCTION: It is known that COVID-19 is associated with venous and arterial thromboembolic events in patients with history of hypertension and atherosclerosis. Herein, it is presented a case of a young woman without known cardiovascular risk, who was infected by SARS-COV 2 and then an ischemic stroke. CASE: 44 years-old woman with moderate COVID-19 in protocolary treatment with anticoagulants, steroid and oxygen. In the seventh day since symptoms onset, she presented acute ischemic stroke due to acute thrombosis of right carotid artery, and right and left medial cerebral arteries, then rapidly developed malignant cerebral edema and brain death. Vascular study failed to report and etiology other than COVID-19. DISCUSSION: It is suggested that the infection produces a systemic inflammatory state, endothelialitis, ulceration of preexisting atherosclerotic plaques, and hypercoagulability that facilitate thrombosis. Ischemic stroke is described in 1 to 5% of COVID-19, it is common to find an elevation of acute phase reactants and products of fibrin metabolism. Multiple vascular territories are usually compromised in patients with known cardiovascular risk factors and 12 days after the onset of symptoms. CONCLUSION: COVID-19 by itself is a risk factor for arterial thrombosis secondary to systemic infection and hypercoagulability states and it should be taken into account in the study of ischemic stroke in young patients.

Se describe el caso clínico de una paciente de 67 años de edad con varias comorbilidades, entre ellas la policitemia vera, quien acudió al Cuerpo de Guardia del Hospital Clinicoquirúrgico Universitario Dr. Ambrosio Grillo Portuondo de Santiago de Cuba por presentar síntomas y signos de un síndrome de abdomen agudo oclusivo. Se indicó intervención quirúrgica de urgencia, que permitió confirmar el diagnóstico presuntivo de afección vascular mesentérica de tipo trombótica. La inmediatez del tratamiento quirúrgico, la reversibilidad del daño vascular sin necesidad de procedimiento de resección intestinal y la administración efectiva de anticoagulantes permitieron una evolución favorable y sin complicaciones.

The case report of a 67 years patient with several comorbidities is described, among them polycythemia vera, who went to the emergency room of Ambrosio Grillo Portuondo University Clinical Surgical Hospital in Santiago de Cuba due to symptoms and signs of a syndrome of occlusive acute abdomen. An emergency surgical intervention was indicated, that confirmed the presumptive diagnosis of mesenteric vascular thrombosis. The immediacy of the surgical treatment, the reversibility of the vascular damage without necessity of intestinal resection procedure and the effective use of anticoagulants allowed a favorable clinical course without complications.

ABSTRACT Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe disease treated with pulmonary endarterectomy. Our study aims to reveal the differences in liquid modalities and operation modifications, which can affect the patients' mortality and morbidity. Methods: One hundred twenty-five patients who were diagnosed with CTEPH and underwent pulmonary thromboendarterectomy (PTE) at our center between February 2011 and September 2013 were included in this retrospective study with prospective observation. They were in New York Heart Association functional class II, III, or IV, and mean pulmonary artery pressure was > 40 mmHg. There were two groups, the crystalloid (Group 1) and colloid (Group 2) liquid groups, depending on the treatment fluids. P-value < 0.05 was considered statistically significant. Results: Although the two different fluid types did not show a significant difference in mortality between groups, fluid balance sheets significantly affected the intragroup mortality rate. Negative fluid balance significantly decreased mortality in Group 1 (P<0.01). There was no difference in mortality in positive or negative fluid balance in Group 2 (P>0.05). Mean duration of stay in the intensive care unit (ICU) for Group 1 was 6.2 days and for Group 2 was 5.4 days (P>0.05). Readmission rate to the ICU for respiratory or non-respiratory reasons was 8.3% (n=4) in Group 1 and 11.7% (n=9) in Group 2 (P>0.05). Conclusion: Changes in fluid management have an etiological significance on possible complications in patient follow-up. We believe that as new approaches are reported, the number of comorbid events will decrease.

ABSTRACT The incidence of diagnosed massive pulmonary embolism presenting to the Emergency Department is between 3% and 4.5% and it is associated with high mortality if not intervened timely. Cardiopulmonary arrest in this subset of patients carries a very poor prognosis, and various treating pathways have been applied with modest rate of success. Systemic thrombolysis is an established first line of treatment, but surgeons are often involved in the decision-making because of the improving surgical pulmonary embolectomy outcomes.

ABSTRACT A 53-year-old man with a 3-day history of periorbital swelling and vision loss in the left eye was found to have septic cavernous sinus thrombosis with bilateral orbital vein involvement causing congestive orbitopathy. He was treated with an emergent canthotomy and cantholysis, intraocular pressure-lowering drops, antibiotics, anticoagulation, and serial examinations. Optical coherence tomography ultimately revealed diffuse ischemic destruction of both layers of the retina, which suggested occlusion of the ophthalmic artery or the short posterior ciliary arteries and central retinal artery without intracavernous internal carotid artery involvement. The patient remained without light perception in the left eye after treatment.

RESUMO Um homem de 53 anos, com história de 3 dias de edema periorbital e perda de visão no olho esquerdo, apresentou trombose séptica do seio cavernoso com envolvimento bilateral das veias orbitais, causando uma orbitopatia congestiva. O paciente foi tratado com uma cantotomia e cantólise de emergência, colírios para redução da pressão intraocular, antibióticos, anticoagulantes e exames seriados. A tomografia de coerência óptica finalmente demonstrou destruição isquêmica difusa de ambas as camadas da retina, sugerindo uma oclusão da artéria oftálmica ou das artérias ciliares posteriores curtas e da artéria retiniana central, com ausência de envolvimento do segmento intracavernoso da artéria carótida interna. O paciente permaneceu sem percepção luminosa no olho esquerdo.

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.
