Project description:BackgroundSince the emergence of COVID-19 pandemic, several cases of cerebral venous sinus thrombosis (CVST) have been reported in SARS-CoV-2 infected individuals.MethodsConsecutive patients with documented SARS-CoV-2 infection, as well as clinical and radiological characteristics of CVST, were reported from three teaching hospitals in the South West, North West, and the center of Iran between June and July 2020. We also searched the abstract archives until the end of August 2020 and gathered 28 reported cases. The diagnostic criteria for SARS-CoV-2 infection were determined according to SARS-CoV-2 detection in oropharyngeal or nasopharyngeal samples in clinically suspected patients. Demographics, prominent COVID-19 symptoms, confirmatory tests for SARS-CoV-2 infection diagnosis, the interval between the diagnosis of SARS-CoV-2 infection and CVST, clinical and radiological features of CVST, therapeutic strategies, CVST outcomes, rate of hemorrhagic transformation, and mortality rate were investigated.ResultsSix patients (31-62 years-old) with confirmed CVST and SARS-CoV-2 infection were admitted to our centers. Four patients had no respiratory symptoms of SARS-CoV-2 infection. Five patients developed the clinical manifestations of CVST and SARS-CoV-2 infection simultaneously. Three patients had known predisposing factors for CVST. Despite receiving CVST and SARS-CoV-2 infection treatments, four patients died. SARS-COV-2 associated CVST patients were older (49.26 vs. 37.77 years-old), had lower female/male ratio (1.42 vs. 2.19), and higher mortality rate (35.29% vs. 6.07%) than CVST not associated with COVID-19.ConclusionsThe role of SARS-CoV-2 as a "cause" versus an "additive contributor" remains to be elucidated. Practitioners should be aware of the possibility of CVST in SARS-CoV-2 infection.
Project description:IntroductionCOVID-19 vaccines became available after being carefully monitored in clinical trials with safety and efficacy on the human body. However, a few recipients developed unusual side effects, including cerebral venous sinus thrombosis (CVST). We aim to systematically review the baseline features, clinical characteristics, treatment, and outcomes in patients developing CVST post-COVID-19 vaccination.MethodsThis study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) 2020 guideline. Investigators independently searched PubMed, Embase, and Google Scholar for English language articles published from inception up until September 10, 2021, reporting the incidence of CVST post-COVID-19 vaccines. We analyzed CVST patients' baseline data, type of vaccines, clinical findings, treatment, and outcomes. Our systematic review process yielded patient-level data.ResultThe final analysis included 25 studies that identified 80 patients who developed CVST after the COVID-19 vaccination. Of the 80 CVST cases, 31 (39.24%) patients died. There was no significant relationship between mortality and age (P = .733), sex (P = .095), vaccine type (P = .798), platelet count (P = .93), and comorbidities such as hypertension (P = .734) and diabetes mellitus (P = .758). However, mortality was associated with the duration of onset of CVST symptoms after vaccination (P = .022). Patients with CVST post-COVID-19 vaccination were more likely to survive if treated with an anticoagulant (P = .039). Patients who developed intracranial hemorrhage (P = .012) or thrombosis in the cortical vein (P = .021) were more likely to die.ConclusionCOVID-19 vaccine-associated CVST is associated with high mortality rate. Timely diagnosis and management can be lifesaving for patients.
Project description:IntroductionCerebral venous sinus thrombosis (CVST) after coronavirus (COVID-19) vaccination has been reported. There are no data about thrombosis risk in prior CVST patients. The objective of the study was to describe short-term serious adverse events to COVID-19 vaccines in patients with history of CVST.Material and methodsWe present an observational prospective study of patients with known CVST who received COVID-19 vaccination. Serious event rates within 30 days after second dose vaccination (except one dose for Janssen) were evaluated, including recurrences, hospital admission and death.ResultsThe 62 vaccinated patients received: BNT162b2 (Pfizer-BioNTech) in 43 patients (69.4%), mRNA-1273 (Moderna) in 7 patients (11.3%), AZD1222 (ChAdOx1) in 7 patients (11.3%) and Ad26.COV2.S (Janssen) in 5 patients (8.1%). There were no thrombotic recurrences within 30 days of vaccination (95% confidence interval, 0.0-5.8). There was one death (1.6%), not attributable to the vaccine.ConclusionsCOVID-19 vaccines are safe for previous CVST patients.

Project description:ObjectiveWe aimed to estimate the incidence of cerebral sinus and venous thrombosis (CVT) within 1 month from first dose administration and the frequency of vaccine-induced immune thrombotic thrombocytopenia (VITT) as the underlying mechanism after vaccination with BNT162b2, ChAdOx1, and mRNA-1273, in Germany.MethodsA web-based questionnaire was e-mailed to all departments of neurology. We requested a report of cases of CVT occurring within 1 month of a COVID-19 vaccination. Other cerebral events could also be reported. Incidence rates of CVT were calculated by using official statistics of 9 German states.ResultsA total of 45 CVT cases were reported. In addition, 9 primary ischemic strokes, 4 primary intracerebral hemorrhages, and 4 other neurological events were recorded. Of the CVT patients, 35 (77.8%) were female, and 36 (80.0%) were younger than 60 years. Fifty-three events were observed after vaccination with ChAdOx1 (85.5%), 9 after BNT162b2 (14.5%) vaccination, and none after mRNA-1273 vaccination. After 7,126,434 first vaccine doses, the incidence rate of CVT within 1 month from first dose administration was 0.55 (95% confidence interval [CI] = 0.38-0.78) per 100,000 person-months (which corresponds to a risk of CVT within the first 31 days of 0.55 per 100,000 individuals) for all vaccines and 1.52 (95% CI = 1.00-2.21) for ChAdOx1 (after 2,320,535 ChAdOx1 first doses). The adjusted incidence rate ratio was 9.68 (95% CI = 3.46-34.98) for ChAdOx1 compared to mRNA-based vaccines and 3.14 (95% CI = 1.22-10.65) for females compared to non-females. In 26 of 45 patients with CVT (57.8%), VITT was graded highly probable.InterpretationGiven an incidence of 0.02 to 0.15 per 100,000 person-months for CVT in the general population, these findings point toward a higher risk for CVT after ChAdOx1 vaccination, especially for women.

Project description:Introduction and importanceSevere acute respiratory distress syndrome coronavirus 2 is the causative agent of COVID-19 (Coronavirus 2019) infection. Although symptoms are usually associated with the respiratory system, its neurological involvement should not be underestimated. The most common cerebrovascular complication following the infection is ischemic stroke however, CVST (Cerebral Venous Sinus Thrombosis) has been reported.Presentation of caseWe report a unique case of a young patient who had a history of headache and abnormal body movement immediately after COVID-19 infection. His brain Computed tomography scan and Magnetic Resonance Imaging (MRI) showed typical images of CVST. He was admitted and treated with Low Molecular weight heparin.DiscussionCVST is a rare form of stroke which may have devastating complications. The diagnosis is clinically challenging due to its non-specific presentation like headache and altered sensorium alone. Inflammatory process and hypoxic state after the virus infection may favor the hypercoagulable state in CVST. Our patient did not have any other predisposing factor for a hypercoagulable state other than the COVID-19 infection.MRI and venography and computed tomographic venography are the preferred modalities. The Patient is generally treated with anticoagulation therapy.ConclusionHigh index of suspicion of CVST is necessary when a patient presents with unexplained neurological manifestation following a recent COVID-19 infection to prevent from life-threatening complications. Furthermore, clinicians should not underestimate the multisystem involvement of COVID-19.
