Cerebral venous sinus thrombosis (CVST) on non-contrast CT (NCCT) is often challenging to detect. We retrospectively selected 41 children and 36 adults with confirmed CVST and two age-matched control groups with comparable initial symptoms. We evaluated NCCT placing four small circular ROIs in standardized regions of the cerebral dural venous system. The mean and maximum HU values were considered from each ROI, and the relative percentage variations were calculated (mean % variation and maximum % variation). We compared the highest measured value to the remaining three HU values through an ad-hoc formula based on the assumption that the thrombosed sinus has higher attenuation compared with the healthy sinuses. Percentage variations were employed to reflect how the attenuation of the thrombosed sinus deviates from the unaffected counterparts. The attenuation of the affected sinus was increased in patients with CVST, and consequently both the mean % and maximum % variations were increased. A mean % variation value of 12.97 and a maximum % variation value of 10.14 were found to be useful to distinguish patients with CVST from healthy subjects, with high sensitivity and specificity. Increased densitometric values were present in the site of venous thrombosis. A systematic, blind evaluation of the brain venous system can assist radiologists in identifying patients who need or do not need further imaging.

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.

Coronavirus disease-2019 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus). Coronavirus disease-2019 (COVID-19) was declared a pandemic in March 2020 and has changed our lives in many ways. This infection induces a hypercoagulable state leading to arterial and venous thrombosis, but the exact pathophysiology of thrombosis is unknown. However, various theories have been postulated including excessive cytokine release, endothelial activation, and disseminated intravascular coagulation (DIC). We present a patient diagnosed with cerebral venous sinus thrombosis (CVST) with COVID-19 infection. A 66-year-old man presented to a hospital for evaluation of persistent headaches. He tested positive for COVID-19, and MRI of the brain and CT venogram revealed CVST. He was started on heparin drip in the hospital and transitioned to oral anticoagulants at the time of discharge. His headaches improved with treatment. Even though headache is the most frequent and initial symptom of cerebral venous thrombosis, it is rarely the only symptom. A high index of suspicion is therefore required to diagnose CVST especially if the patient presents with a simple complaint like a headache. Common complaints can delay the diagnosis leading to disease progression. Considering the high mortality rates in patients diagnosed with CVST, we suggest the importance of knowing the association between COVID-19 infection and CVST, especially in susceptible patients.

Background: The clinical presentation of cerebral venous sinus thrombosis (CVST) overlaps with that of idiopathic intracranial hypertension (IIH), but no screening tool exists. We investigated the role of eye-neck integrated ultrasound in the diagnosis and differentiation of IIH and CVST.Methods: Twenty IIH patients, 30 CVST patients, and 40 healthy controls were retrospectively analyzed. The ultrasonographic optic nerve sheath diameter (ONSD) and hemodynamic characteristics of the internal jugular veins (IJVs) were recorded. The cerebrospinal fluid opening pressure was measured after ultrasonic examination.Results: The ONSD was significantly larger in IIH patients than in controls (4.71 ± 0.41 vs. 3.93 ± 0.24 mm, p < 0.001). The ONSD cut-off for IIH diagnosis was 4.25 mm (AUC = 0.978; 95% CI: 0.95–1.0, p < 0.001, sensitivity: 90%, specificity: 93%). In the CVST group, 22 (73.3%) patients had elevated intracranial pressure (ICP); the mean ONSD was significantly higher in patients with increased ICP than in those without (4.43 ± 0.33 vs. 3.95 ± 0.17 mm, p < 0.001). The mean blood flow volume (BFV) was significantly reduced in CVST patients (425.17 ± 349.83 mL/min) compared to that in controls (680.37 ± 233.03 mL/min, p < 0.001) and IIH patients (617.67 ± 282.96 mL/min, p = 0.008). The optimal BFV cut-off for predicting CVST was 527.28 mL/min (AUC = 0.804, 95% CI: 0.68–0.93, p < 0.001, sensitivity: 80%, specificity: 78%). The velocity of the unilateral IJVs-J3 segment decreased or remained constant during deep inspiration (abnormal respiratory modulate blood flow test, ARMT) in 32.5% of controls, with no bilateral ARMT. The prevalence of bilateral ARMT was 25% in IIH patients (χ2 = 12.9, p = 0.005) and 27% in CVST patients (χ2 = 17.6, p = 0.001).Conclusion: Eye-neck integrated ultrasound is an easily available bedside technique to assess ICP and hemodynamic characteristics of IJVs. ONSD measurement can identify patients with increased ICP, and reduced IJV BFV may aid the differentiation of CVST and IIH.

Introduction. Risk factors for thrombotic events in patients receiving treatment for Hodgkin lymphoma are not well known. Administration of some cytostatic medication, especially via central venous catheter, corticosteroids and hyperlipidemia can present some of them. Case outline. A case of a 15-year-old boy that had been newly diagnosed with Hodgkin lymphoma is presented here. Chemotherapy according to vincristine, etoposide, prednisone, and doxorubicin (OEPA) protocol was introduced a month before headache and vomiting occurred, so subsequently, brain- computer tomography (CT) was performed, and reviled laminar subdural pseudo hemorrhage in the right occipital region. After performing magnet resonance imaging (MRI) venous thrombosis of the posterior part of superior sagittal sinus, right transverses and sigmoid sinus were presented. Low-molecular-weight heparin (LMWH) and anti-edematous therapy was immediately initiated. Two weeks later the patient resumed the second cycle of chemotherapy combined with LMWH, as the previous symptoms of intracranial hypertension resolved. Two years after MRI showed almost complete resolution of finding. The boy was in good clinical condition. Conclusion. Although administration of oral corticosteroids, could be rarely a risk factor per se for cerebral sinus venous thrombosis in HL patients, it remains important treatment option. Adequate and prompt diagnostics and therapy are mandatory in cases of wide intracranial venous thrombosis as prevention of possible intracranial hypertension and even fatal outcome.

Introduction. Cerebral venous sinus thrombosis (CVST) is a rare form of cerebrovascular disease, which may manifest clinically by a wide variety of signs and symptoms. It has been associated with multiple risk factors including genetic or acquired blood disorders, infections, and trauma.Case Report. Man of 17 years who presented with 10 days of intense global headache with nausea and vomiting and subsequent onset of mild hemiparesis and hypoesthesia in right hemibody. Studies show venous thrombosis of the superior longitudinal sinus. It was identified a gene mutation in prothrombin G20210A as a probable cause of the thrombosis.Conclusions. Substitution of guanine for adenine at nucleotide 20210 in the coding region of the prothrombin gene is the second most common primary thrombophilia. Multiple cases of CVST have been associated with this mutation. In the presence of CVST must be considered the primary studies for thrombophilia gene mutations, including prothrombin G20210A.

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.
