Background: Although the majority of those infected by COVID-19 develop an asymptomatic or mild condition, there are those who evolve to a critical condition, such as Cerebral Venous Thrombosis (CVT), which deserves attention, as it is a neurovascular emergency. Objectives: The objective of the abstract is to analyze CVT as a complication of COVID-19. Design and setting: This is an integrative literature review, conducted in the Pubmed database. Methods: The descriptor “cerebral venous thrombosis covid” was used. The inclusion criteria were English studies published in 2020. The exclusion criteria were the non- relevance of the information to the theme. In all, 7 articles were selected. Results: It was observed that most patients were middle-aged men diagnosed with CVT after 7 days of Covid-19 discharge. CVT may be associated with endotheliitis caused by the virus interaction with the Angiotensin Converting Enzyme receptor, also with an abnormal proliferation of cytokines, and both of them favor vasoconstriction and hypercoagulopathy. It has been proposed that the disease may induce a prothrombotic state by the elevated levels of circulating fibrinogen, D-dimer, and pro-thrombotic microparticles. Furthermore, increasing levels of antiphospholipid antibodies detected in patients with COVID-19, such as anti-cardiolopin IgA, anti-β2-glycoprotein I IgA and IgG may precipitate hypercoagulability and vascular infarctions. Conclusion: This review shows the influence of the post-COVID on the occurrence of TVC. However, the studies are still incipient and have not systematically described other previous prothrombotic conditions that may be additive factors.

AbstractBackground: Cerebral venous thrombosis is a rare cause of stroke, with a number of well-defined risk factors. However, there exist few studies that describe trends in the prognosis of this disease over time. Methods: A retrospective study was performed on patients diagnosed with cerebral venous thrombosis at the University of Alberta Hospital during two time periods: 1988-1998 (21 patients) and 1999-2009 (40 patients). Signs and symptoms, risk factors, imaging findings, etiologies, treatment modalities, and status at discharge were examined. Results: Headache, nausea and vomiting, focal motor deficit, and seizure were the most common signs and symptoms, and active hormonal contraception was the most commonly identified risk factor between the two cohorts. Hematoma and hyperdense sinuses were the most commonly identified CT findings between groups. Thrombophilia and the use of hormonal contraception were the most frequently identified etiologies between the two cohorts. Treatment was similar, with the majority of patients in both cohorts receiving unfractionated heparin as first-line therapy. Patients in the 1999-2009 cohort were significantly less likely to have a severe deficit or be dead at discharge (odds ratio [OR]=0.178; 95% confidence interval [CI95%]=0.051, 0.625) and were more likely to have a favorable modified Rankin Scale score of 0 or 1 at discharge (OR=7.98; CI95%=1.79, 35.71). Conclusions: Our data indicate a reduction in severe residual symptoms at discharge and improved functional status at discharge for patients presenting with cerebral venous thrombosis from 1999 to 2009, as compared with 1988-1998.

Thrombosis of cerebral venous channel is a known complication of hypercoagulable states. Hyperhomocysteinaemia is a known hypercoagulable state. Obesity is a modern-day global epidemic. Disorders such as myocardial infarction (MI), stroke, and venous thromboembolism are on the rising trend and its increased morbidity and mortality is being associated with obesity. To date, however, the knowledge about the association between obesity and adult cerebral venous thrombosis (CVT) is sparse. We report a 44-year-old young morbidly obese metabolically unhealthy female who presented with headache, nausea, vomiting and giddiness. On evaluation, magnetic resonance venogram showed cerebral venous sinus thrombosis. On investigations, she had concomitant hyperhomocysteinaemia and metabolic syndrome. Cerebral venous sinus thrombosis causing stroke in young adults is uncommon with various conditions precipitating it.1,2,3 Severe headache (70 - 90 %), focal lateralized signs (25 % - 75 %), seizures (30 – 40 %) as well as behavioural symptoms such as delirium, amnesia, and disturbances in consciousness are the various associated clinical symptoms. The known inherited hypercoagulable risk factors that cause CVST are gain of function mutations in the genes encoding factor V (factor V Leiden) and prothrombin, Protein C, S and antithrombin III deficiency. Hyperhomocysteinaemia, is a known risk factor for causing venous thrombosis of the lower limbs. However, till date there is no data available showing its role in causing cerebral venous thrombosis. The interaction between genetic and acquired determinants result in high plasma levels of total homocysteine (tHcy).4,5,6 Vitamins such as folic acid, pyridoxine, and cobalamin are involved in the metabolic pathways of homocysteine and its deficiencies represent the acquired determinants. Venous thromboembolism (VTE) comprises of deep vein thrombosis of the leg and pulmonary embolism and obesity is now being recognised as one of the risk factors causing it. The risk of VTE is approximately increased to 2-fold in an individual with a body mass index (BMI) (calculated as weight in kilograms divided by height in meters squared) of 30 or more compared with a normal BMI (< 25), and higher BMIs increase more risk with approximately 3 times higher risk in individuals with a BMI greater than 40.7, 8,9 Again obesity as a risk factor for CVST is less known.

Patients with cerebral venous thrombosis (CVT) pre-sent with a range of symptoms, which varies widely from headache to coma. Chronic occlusion of venous dural sinuses leads to the initiation of compensation processes, such as vascular collatera-lization, recanalization of the organized thrombus. Consequently, their efficacy determines disease course and severity. The purpose of our study was to highlight the clinical challenges while managing a patient with subcompensated CVT. Taking into account the fact that mild severity is observed in 20 % of cases, eventually, about a quarter of patients presenting with the headache of unclear etio-logy becomes unnoticed and results in low quality of life. To analyze the disease outcome and prognosis, we accurately studied compensation mechanisms, which occur in a patient due to cerebral venous sinus thrombosis, notably venous collateral circulation and thrombus recanalization. However, the most important “pitfall” of chronic dural sinuses occlusion, when not appropriately treated, is the fact that hemodynamic compensation also leads to a high risk of cerebrovascular events, which may lead to death or disabi-lity. The patient with cerebral venous thrombosis of the transverse and sigmoid sinuses manifested migraine-like headache with a vegetative issue and signs of increased intracranial pressure. Due to the absence of anticoagulant therapy, venous drainage through collateral pathways and recanalization of thrombosed sinuses were insufficient to maintain a cerebral blood supply, resulting in diffuse cerebral edema, secondary brain injury. After an accurate survey, diagnostic procedures, prescribing of individualized treatment, and long-term follow-up with correction of therapy the patient experienced regression of CVT symptoms. Cerebral MRI venography is an important tool for the diagnosis and prediction of the prognosis of this condition. Thus, patients with a long history of untreatable headache and signs of intracranial hypertension should undergo this procedure. To consider intracranial vascular events and outcomes, the venous hemodynamics should be evaluated. Moreover, it is often necessary to examine cerebral veins and sinuses, when hemorrhagic stroke does not correspond to cerebral arterial territories and has unclear etiology.

Cerebral venous thrombosis (CVT) is occlusion of dural sinuses and/or cortical veins due to clot formation. It is a potentially   life-threatening condition that requires rapid diagnosis and urgent treatment.Cerebral venous thrombosis is   more common in   females and young people. Pregnancy, postpartum state, contraceptive pills,  infection, malignancy,  hyper-coagulable state, rheumatological disorders, trauma are among the major etiologies of cerebral venous thrombosis. Headache, focal neurologic deficits and seizure were the most common clinical presentations. Different techniques of unenhanced and contrast enhanced   brain  computerized tomography(CT scan)  and ,magnetic resonance imaging(MRI) are the most helpful ancillary investigations for diagnosis of Cerebral venous thrombosis.Specific treatment  of the underlying cause of cerebral venous thrombosis should be considered as the mainstay of the treatment. Anticoagulation with heparin or low molecular weight heparinoids  is  the most accepted treatment. In acute phase, medical   or surgical management to decrease intracranial pressure (ICP) is   also recommended. If the patient's clinical   condition aggravates despite adequate anticoagulation, thrombolysis  or mechanical thrombectomy can be an additive option.

This is a rare presentation of scrub typhus with cerebral venous thrombosis. A 32-year-old woman presented with signs of raised intracranial tension. Examination revealed maculopapular skin rashes and an ‘eschar’ over the right thigh. Nuchal rigidity and bilateral papilloedema were found. Scrub typhus was diagnosed by the presence of IgM antibody in serum. CT scan of the brain showed cerebral oedema. MRI of the brain was normal. Magnetic resonance venography of the brain showed thrombosis of several venous sinuses. Cerebrospinal fluid analysis revealed lymphocytic pleocytosis with raised protein level. Other causes of prothrombotic states were ruled out by doing specific test results. There was no history of hormonal contraception and prolonged bed rest. A case of scrub typhus complicated with meningoencephalitis and cerebral venous thrombosis was diagnosed. She responded to treatment with doxycycline, anticoagulants, antipyrectics and intravenous saline. Early identification of such atypical neurological involvement in scrub typhus was helpful in satisfactory outcome.

Introduction: Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) was first detected in December 2019 in the city of Wuhan, China, and has since taken on worldwide proportions. It is known that individuals with Coronavirus disease-19 (COVID-19) have systemic clinical manifestations. Among the multisystemic effects, cerebral venous thrombosis (CVT) is responsible for high mortality rates. In this sense, understanding the association between CVT and SARS-CoV-2 infection directly impacts the disease's morbidity and mortality. Methodology: Literature review in the PubMed and Embase databases, with the following search terms: “COVID-19”, “SARS-CoV-2”, “Venous thromboembolism”, “Thrombosis”, “Cerebral Venous Thrombosis”, “Intracranial Sinus Thrombosis” and “Cranial Sinus Thrombosis”. The selected articles were written in English, which addressed the various aspects of COVID-19. Results and discussion: CVT are a rare complication of COVID-19, with an incidence between 0.02 to 1% of hospitalized patients. However, it can reach about 75% of mortality in affected individuals. Pathophysiology seems to be associated with the state of hypercoagulability and the systemic inflammatory process resulting from viral infection. Thus, recent studies show a consensus on the early anticoagulation of patients affected by the virus, to reduce mortality in these cases. However, the differences between the types of anticoagulation, Low Molecular Weight Heparin (LMWH), Unfractionated Heparin (UFH), Dabigatran have not yet been well established, although there is a predilection for the use of LMWH. Also, thrombectomy is a therapeutic intervention option that should be evaluated, due to the risk of additional endothelial injury from the use of stent retrievers. Conclusion: Although it has a relatively low incidence, CVT aggravates the condition and increases the risk of death for patients with COVID-19. Because of this, early diagnosis and evaluation of therapeutic options for CVT are essential for the development of clinical management.

Background. Early diagnosis of cerebral venous sinus thrombosis (CVST) associated with reproductive health-related risk factors (RHRF) including pregnancy, puerperium, and oral contraceptive (OC) use can prevent severe neurological sequelae; thus, the symptoms must be documented in detail for each group. Methods. Out of 1144 patients with CVST, a total of 777 women were enrolled from a multicenter for the study of cerebral venous sinus thrombosis (VENOST). Demographic, biochemical, clinical, and radiological aspects were compared for 324 cases with RHRF and 453 cases without RHRF. Results. The mean age of the RHRF (-) group (43.2 ± 13 years) was significantly higher than of the RHRF (+) group (34±9 years). A previous history of deep venous thrombosis (3%), isolated cavernous sinus involvement (1%), cranial neuropathy (13%), comorbid malignancy (7%), and its disability scores after 12 months (9%) were significantly higher in the RHRF (-) group. The RHRF (+) group consisted of 44% cases of puerperium, 33% cases of OC users and 23% of pregnant women. The mean age was found to be higher in OC users (38±9 years). A previous history of deep venous thrombosis was slightly higher in the pregnancy subgroup (4%). Epileptic seizures were more common in the puerperium group (44%). Conclusion. The results of our study indicate that the risk of CSVT increases parallel to age, OC use, and puerperium period. In addition, when considering the frequency of findings and symptoms, epileptic seizures in the puerperium subgroup of the RHRF (+) group and malignancies in the RHRF (-) group may accompany the CSVT. In daily practice, predicting these risks for the CSVT and early recognition of the symptoms will provide significant benefits to patients.

Abstract Cerebral venous thrombosis (CVT) represents 1% of the total stroke pathology but is a real challenge both regarding the diagnosis and the treatment. Objective: Evaluate different etiological, demographical, clinical, imaging and therapeutic aspects of CVT. Material: Prospective study during 4 years. From the total 3658 patients hospitalized with acute stroke, 45 (1.23%) had CVT. For each patient, were recorded: demographic data, symptom of onset, type of onset, daily habits, medical history, neurological examination, brain imaging (CT and MRI with venography). Statistical analysis: data are presented as mean and SD and Student t test was applied. Results: Mean age was 44.07± 23,12 years; female: male ratio 2.21:1. The most frequent type of onset was acute (77.78%). Headache was found in 80% of cases as initial symptom, followed by neurological focal deficits. As risk factors, thrombophilia was found most often (59.5%), followed by local infections. No risk factors were found in 17.8% of cases. The brain imaging was positive in 29 patients. In 16 cases, the imaging workout was negative and the diagnosis consisted of clinical criteria, risk factors, response to heparin treatment. Conclusions: CVT is a rare pathology that affects mainly young women and that needs a complex diagnostic evaluation. The patient prototype diagnosed with CVT in our region: female of 44 years old, with an intense acute headache, with MRI showing direct signs of transverse sinus thrombosis, with a thrombophilic state and good response to anticoagulants. Brain MRI is the imaging investigation required but clinical aspects play a decisive role.

Background Cerebral venous thrombosis (CVT) is a rare disease, and with poor prognosis. Computed tomography (CT) and magnetic resonance imaging (MRI) are the most commonly used image modalities for patients with non-specific neurologic symptoms. We present here a meta-analysis to assess the accuracy of CT and MRI in the differential diagnosis of CVT and cerebral venous sinus thrombosis (CVST). Materials and Methods A comprehensive search of the PubMed, EMBASE, Web of Science, Cochrane Database and Chinese Biomedical (CBM) databases was conducted prior to March 20, 2017. In this report, we assess the methodological quality of each article individually and perform a meta-analysis to obtain the summary of the diagnostic accuracy of CT and MRI in correctly identifying CVT and CVST. Results Twenty-four eligible articles comprising 48 studies (4,595 cases) were included. The pooled sensitivity for CT–CVT/CT–CVST groups is 0.79 (95% confidence interval [CI]: 0.76, 0.82)/0.81(95% CI: 0.78, 0.84), and pooled specificity is 0.90 (95% CI: 0.89, 0.91)/0.89 (0.88, 0.91), with an area under the curve (AUC) for the summary receiver operating characteristic (SROC) of 0.9314/0.9161, respectively. No significant heterogeneity and publication bias was observed across each study. For MRI–CVT/MRI–CVST, the pooled sensitivity is 0.82 (95% CI: 0.78, 0.85)/0.80 (95% CI: 0.76, 0.83), and pooled specificity is 0.92 (95% CI: 0.91, 0.94)/0.91(0.89, 0.92), with an AUC for the SROC of 0.9221/0.9273, respectively. Conclusion This meta-analysis indicates that both CT and MRI have a high level of diagnostic accuracy in the differential diagnosis of CVT and CVST, independent of stage, target for analysis or analysis methods. They could be chosen as alternative sub-optimal gold standards for diagnosing CVT and CVST, especially in emergency.

Abstract Background  Celiac disease is a digestive inflammatory syndrome with several complications. It is associated with coagulation and platelets abnormalities leading to thromboembolic events. Cerebral venous thrombosis is an exceptional localization of thrombosis in celiac disease and could be life-threatening. Case summary  A 17-year-old female patient with history of celiac disease and not following a gluten-free diet, checked in to the emergency department for a sudden, 2-week-old, and deteriorating, onset of intense headache and muscle weakness. The cerebral computed tomography-scan showed bilateral fronto-parietal hypodensity with micro-bleeds. We investigated using a cerebral magnetic resonance imaging that revealed superior longitudinal sinus thrombosis and right transverse and sigmoid sinuses thrombosis, along with right haematoma and ischaemic areas. The patient was prescribed anticoagulation therapy. Follow-ups over a 2-year period confirmed a favourable outcome and a complete regression of symptoms. Discussion  Evolution of celiac disease could be associated with several complications. Eighty-five percent of patients is potentially exposed to thromboembolic events due to the hypercoagulability state of the disease and different coagulation and fibrinolysis abnormalities (e.g. hyperhomocysteinaemia, protein C and S deficiencies, vitamin K and B deficiencies). Cerebral venous thrombosis is a rare thromboembolic localization. Anticoagulation is efficient in most cases though endovascular treatment might be required.
