RESUMEN
AIMS: This study aimed to unravel the dehydration status of patients with cerebral venous sinus thrombosis (CVST) to facilitate the understanding of dehydration in CVST. METHODS: This was a multicenter retrospective study and three populations were recruited, namely, patients with CVST, CVST mimics, and healthy subjects. Blood samples were obtained 1-2 days after admission to assess dehydration status. Stata 15.1 was performed for statistical analysis. RESULTS: A total of 208 patients were diagnosed with CVST, 237 with CVST mimics, and 200 healthy individuals were enrolled. The urine specific gravity (USG, 1.020 [1.014, 1.029] vs. 1.017 [1.011, 1.021]) was higher in patients with CVST than in those with mimics (all p < 0.001). The percentage of USG >1.03 was also higher in CVST (22.6%) than in its mimics (6.3%, p < 0.001). With the development of CVST, USG (acute vs. sub-acute vs. chronic, 1.022 [1.015, 1.033] vs. 1.021 [1.015, 1.031] vs. 1.019 [1.014, 1.025]) decreased. All dehydration-related markers could not differentiate CVST from its mimics and healthy populations, and they were not associated with CVST severity and prognosis (p > 0.05). CONCLUSION: High levels of USG, especially USG >1.013, were more common in patients with CVST. Dehydration-related indices could not characterize CVST and were not associated with CVST severity and prognosis.

BACKGROUND: Increasing evidence suggests that inflammatory biomarkers play a significant role in cerebral venous sinus thrombosis (CVST). The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) are related to thrombotic conditions and indicators of systemic inflammation. OBJECTIVE: To analyze the correlation between inflammatory biomarkers and the extent of thrombus, determined by the CVST-Score. METHODS: A total of 40 patients with CVST (24 female subjects; 60%) and 40 age- and sex-matched healthy controls were retrospectively evaluated. Inflammatory biomarkers, including C-reactive protein (CRP), PLR, NLR, MLR, and the CVST-Score, were recorded to assess the relationship between biomarkers and thrombus burden. The patients were grouped according to symptom duration (group 1: 0-3 days; group 2: 4-7 days; and group 3: 8-30 days) to compare biomarker levels. RESULTS: The CRP, NLR, and PLR were significantly higher in the CVST group (p < 0.001; p = 0.003; p = 0.014 respectively). The NLR and PLR presented a significant positive correlation with the CVST-Score (p = 0.003, r = 0.464; p = 0.040, r = 0.326 respectively). The NLR was significantly higher in group 1 compared with groups 2 and 3 (p = 0.016 and p = 0.014 respectively). In group 1, there was a stronger positive correlation between the CVST-Score and the NLR (p = 0.026, r = 0.591) and the PLR (p = 0.012, r = 0.648). The multiple linear regression analysis revealed that the NLR is a key factor in predicting the CVST-Score (p = 0.019). CONCLUSION: The NLR and PLR are associated with thrombus burden in CVST, especially in patients admitted to the hospital in the early stages. The NLR is an independent factor to predict the thrombus burden in CVST.
ANTECEDENTES: Há evidências crescentes de que biomarcadores inflamatórios desempenham um papel importante na trombose venosa cerebral (TVC). A razão neutrófilo-linfócito (NLR), a razão plaqueta-linfócito (PLR) e a razão monócito-linfócito (MLR) estão relacionadas a condições trombóticas e são indicadores de inflamação sistêmica. OBJETIVO: Analisar a correlação entre NLR, PLR, MLR e a extensão do trombo, determinada pelo escore de TVC. MéTODOS: Avaliamos retrospectivamente 40 pacientes com TVC (24 mulheres; 60%) e 40 controles pareados por idade e sexo. Biomarcadores inflamatórios, incluindo proteína C reativa (PCR), PLR, NLR, MLR e escore de TVC, foram registrados para avaliar a relação entre biomarcadores e carga trombótica. Os pacientes foram agrupados de acordo com a duração dos sintomas (grupo 1: 03 dias; grupo 2: 47 dias; e grupo 3: 830 dias) para a comparação dos níveis de biomarcadores. RESULTADOS: A PCR, a NLR e a PLR foram significativamente maiores no grupo com TVC (p < 0,001; p = 0,003; e p = 0,014, respectivamente). A NLR e a PLR apresentaram correlação positiva significativa com o escore de TVC (p = 0,003, r = 0,464; e p = 0,040, r = 0,326, respectivamente). A NLR foi significativamente maior no grupo 1 em comparação aos grupos 2 e 3 (p = 0,016 e p = 0,014, respectivamente). No grupo 1, houve correlação mais forte entre o escore de TVC e a NLR (p = 0,026, r = 0,591) e a PLR (p = 0,012, r = 0,648). A análise de regressão linear múltipla identificou a NLR como fator-chave na predição do escore de TVC (p = 0,019). CONCLUSãO: A NLR e a PLR estão associadas à carga trombótica na TVC, especialmente em pacientes admitidos precocemente, e a RNL é um fator independente na previsão da carga trombótica.

BACKGROUND AND PURPOSE: Cerebral sinus venous thrombosis (CSVT) is a rare but life-threatening disease and its diagnosis remains challenging. Blood biomarkers, including D-Dimer are currently not recommended in guidelines. Soluble endothelial receptor proteins (sICAM-1, sPECAM-1 and sVCAM-1) have been shown to be promising diagnostic biomarkers in deep vein thrombosis (DVT) and pulmonary embolism (PE). Therefore, we examined endothelial receptor proteins as potential biomarkers for detecting CSVT. METHODS: In this bi-centre, prospective study, we quantified D-Dimer as well as sICAM-1, sPECAM-1 and sVCAM-1 in plasma of patients with clinically suspected CSVT managed in the neurological emergency department (ED) of a tertiary care hospital. All patients underwent cerebral magnetic resonance imaging (MRI) and were followed up after 3, 6 and 12 months to detect thrombus resolution. RESULTS: Twenty-four out of 75 (32%) patients with clinically suspected CSVT presenting with headache to the ED were diagnosed with acute CSVT. These patients had a mean age of 45 ± 16 years and 78% were female. In patients with CSVT, mean baseline D-dimer (p < 0.001) and sPECAM-1 (p < 0.001) were significantly higher compared to patients without CSVT. The combination of D-Dimer and sPECAM-1 yielded the best ROC-AUC (0.994; < 0.001) with a negative predictive value of 95.7% and a positive predictive value of 95.5%. In addition, higher baseline sPECAM-1 levels (> 198 ng/ml) on admission were associated with delayed venous thrombus resolution at 3 months (AUC = 0.83). CONCLUSION: sPECAM-1 in combination with D-Dimer should be used to improve the diagnostic accuracy of acute CSVT and sPECAM-1 may predict long-term outcome of CSVT. Confirmatory results are needed in other settings in order to show their value in the management concept of CSVT patients.

Importance: Thrombosis with thrombocytopenia syndrome (TTS) has been reported after vaccination with the SARS-CoV-2 vaccines ChAdOx1 nCov-19 (Oxford-AstraZeneca) and Ad26.COV2.S (Janssen/Johnson & Johnson). Objective: To describe the clinical characteristics and outcome of patients with cerebral venous sinus thrombosis (CVST) after SARS-CoV-2 vaccination with and without TTS. Design, Setting, and Participants: This cohort study used data from an international registry of consecutive patients with CVST within 28 days of SARS-CoV-2 vaccination included between March 29 and June 18, 2021, from 81 hospitals in 19 countries. For reference, data from patients with CVST between 2015 and 2018 were derived from an existing international registry. Clinical characteristics and mortality rate were described for adults with (1) CVST in the setting of SARS-CoV-2 vaccine-induced immune thrombotic thrombocytopenia, (2) CVST after SARS-CoV-2 vaccination not fulling criteria for TTS, and (3) CVST unrelated to SARS-CoV-2 vaccination. Exposures: Patients were classified as having TTS if they had new-onset thrombocytopenia without recent exposure to heparin, in accordance with the Brighton Collaboration interim criteria. Main Outcomes and Measures: Clinical characteristics and mortality rate. Results: Of 116 patients with postvaccination CVST, 78 (67.2%) had TTS, of whom 76 had been vaccinated with ChAdOx1 nCov-19; 38 (32.8%) had no indication of TTS. The control group included 207 patients with CVST before the COVID-19 pandemic. A total of 63 of 78 (81%), 30 of 38 (79%), and 145 of 207 (70.0%) patients, respectively, were female, and the mean (SD) age was 45 (14), 55 (20), and 42 (16) years, respectively. Concomitant thromboembolism occurred in 25 of 70 patients (36%) in the TTS group, 2 of 35 (6%) in the no TTS group, and 10 of 206 (4.9%) in the control group, and in-hospital mortality rates were 47% (36 of 76; 95% CI, 37-58), 5% (2 of 37; 95% CI, 1-18), and 3.9% (8 of 207; 95% CI, 2.0-7.4), respectively. The mortality rate was 61% (14 of 23) among patients in the TTS group diagnosed before the condition garnered attention in the scientific community and 42% (22 of 53) among patients diagnosed later. Conclusions and Relevance: In this cohort study of patients with CVST, a distinct clinical profile and high mortality rate was observed in patients meeting criteria for TTS after SARS-CoV-2 vaccination.

Most of the knowledge in pediatric antiphospholipid syndrome (APS) is derived from studies performed on the adult population. As in adults, antiphospholipid antibodies (aPL) can contribute to thrombosis, especially cerebrovascular thrombosis, in neonates and children. Since aPL have the potential to cross the placental barrier, and since the pediatric population is prone to infections, re-testing for their positivity is essential to specify their role in cerebrovascular thrombosis.In this review, we aimed at assessing the prevalence of aPL, criteria or non-criteria, in neonatal and childhood ischemic stroke and sinovenous thrombosis trying to find an association between aPL and cerebrovascular thrombosis in the neonatal and pediatric population. Also, we looked into the effect of aPL and anticoagulants/antiplatelets on the long term neurological outcomes of affected neonates or children. The questions regarding the prevalence of aPL among pediatric patients with cerebrovascular thrombosis, the relationship between the titers of aPL and incidence and recurrence of cerebrovascular events, the predictability of the long term neurological outcomes, and the most optimal anticoagulation plan are still to be answered. However, it is crucial for clinicians to screen neonates and children with cerebrovascular thrombosis for aPL and confirm their presence if positive.

BACKGROUND: The role of inflammation in the prognosis of cerebral venous sinus thrombosis (CVST) has been demonstrated in a small number of studies. The platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and the systemic immune-inflammatory index (SII) have been studied as prognostic inflammatory biomarkers in numerous thrombo-embolic diseases. However, the number of studies evaluating the relationship between these parameters and CVST is very low. OBJECTIVE: The purpose of this retrospective study was to investigate the relationship between PLR, NLR, and SII values on admission and long-term prognosis in patients with CVST in the acute-subacute period. METHODS: Fifty-one patients diagnosed with CVST and 51 healthy controls were included in the study. The patient and control groups were compared in terms of NLR, PLR, and SII values. Patients were classified into good and poor prognosis groups based on sixth-month modified Rankin scale scores (mRS) (0-2: good prognosis, 3-6: poor prognosis). Clinical and radiological features and PLR, NLR, and SII values were compared between the good and poor prognosis groups. Multivariate logistic regression analysis was used to identify independent prognostic factors for poor prognosis. The Receiver Operating Curve (ROC) was used to demonstrate the predictive power of PLR, NLR, and SII. RESULTS: Higher NLR and SII emerged as independent factors for poor prognosis in patients with CVST. NLR was the strongest parameter in predicting poor prognosis in CVST (AUC: 0.817, 95% CI: 0.63-1.00, sensitivity 70%, specificity 92.7%, p:0.002). CONCLUSION: Higher NLR and SII on admission may be a predictor of long-term poor prognosis in patients with acute-subacute CVST.

OBJECTIVE: The aim of this study was to explore the clinical efficacy of conventional heparin anticoagulation in combination with apixaban in the treatment of patients with cerebral venous thrombosis (CVT) and its influence on serum D-dimer (D-D) and fibrinogen (FIB). METHODS: One hundred and fifty-seven consecutive CVT patients admitted to our hospital from January 1, 2006, to December 31, 2013, were allocated into two groups according to the different treatment methods, of which 95 cases received standard anticoagulation therapy (standard group (SG)) and the remaining 62 cases were given apixaban therapy (research group (RG)). The curative effects and the changes of coagulation function during the treatment, as well as the incidence of adverse reactions, were analyzed in the two groups. The changes of D-D and FIB levels before treatment and at days 1, 4, and 7 posttreatment were detected. RESULTS: In treatment efficacy, RG was superior to SG. No evident difference was observed in the incidence of adverse events or coagulation function between the two groups. At day 1 posttreatment, D-D level was increased largely in both SG and RG, but the increase was much more significant in RG. However, D-D level was decreased gradually with time in both groups, and the reduction was more notable in RG. The FIB level in SG declined gradually with time after treatment and was higher than that in RG at the same time point. In RG, FIB was decreased gradually at day 1 and day 4 posttreatment, and its level at day 7 posttreatment showed no difference compared with that at day 4 posttreatment. Spearman's analysis identified that the higher the D-D level or the lower the FIB level at day 1 posttreatment was, the better the treatment efficacy was. After seven-day treatment, the lower the level of D-D and FIB was, the better the therapeutic effect was. Logistic analysis indicated that age, time of diagnosis, deep vein thrombosis (DVT), Glasgow Coma Scale (GCS) score, infection, Apixaban, D-D, and FIB all independently affect the treatment effect of patients. CONCLUSIONS: The combined use of Apixaban with heparin is high-performing and safe in the treatment of CVT. The changes of D-D and FIB levels during the treatment are strongly linked to the therapeutic effect, which can be used as plausible evaluation indexes for the efficacy of CVT.

OBJECTIVES: To evaluate the diagnostic performance of unenhanced brain CT (NECT) in identifying patients with cerebral venous sinus thrombosis (CVT). METHODS: Forty-eight consecutive patients with CVT and 48 healthy controls were included in our retrospective study. All patients underwent NECT and CT/MR angiography within 24 h. Two radiologists independently evaluated NECT images for the presence of sinus hyperdensity; discrepancies were solved by consensus. Sinus attenuation was measured in seven sites. The obtained data were compared with the presence of CVT at CT/MR angiography and with patients' hematocrit. RESULTS: Interobserver agreement in sinus hyperdensity detection was good (k = 0.64). The presence of sinus hyperdensity at NECT enabled to detect patients with CVT with 81% sensitivity, 77% specificity, 78% PPV, and 80% NPV. Mean attenuation was significantly higher in sinus segments involved by CVT than in patent ones (62.4 ± 10 versus 55.6 ± 6 HU, p < 0.0001). ROC analysis showed that a cutoff value of 63 HU enables to detect patients with CVT with 52% sensitivity and 88% specificity. Hematocrit values were significantly correlated with patent sinus segments attenuation (r = 0.19). CONCLUSIONS: The presence of sinus hyperdensity at NECT enables to detect patients with CVT with 81% sensitivity and 77% specificity. A sinus attenuation cutoff value of 63 HU can be used in order to increase specificity, but lowering sensitivity.

BACKGROUND: There has been increasing reports associating the coronavirus disease 2019 (COVID-19) with thromboembolic phenomenon including ischemic strokes and venous thromboembolism. Cerebral venous thrombosis (CVT) is a rare neurovascular emergency that has been observed in some COVID-19 patients, yet much remains to be learnt of its underlying pathophysiology. OBJECTIVE: We present a case series of local patients with concomitant COVID-19 infection and CVT; and aim to perform a systematic review of known cases in the current literature. METHODS: We describe two patients with concomitant COVID-19 infection and CVT from a nationwide registry in Singapore. We then conducted a literature search in PubMed and Embase using a suitable keyword search strategy from 1st December 2019 to 11th June 2020. All studies reporting CVT in COVID-19 patients were included. RESULTS: Nine studies and 14 COVID-19 patients with CVT were studied. The median age was 43 years (IQR=36-58) and majority had no significant past medical conditions (60.0%). The time taken from onset of COVID-19 symptoms to CVT diagnosis was a median of 7 days (IQR=6-14). CVT was commonly seen in the transverse (75.0%) and sigmoid sinus (50.0%); 33.3% had involvement of the deep venous sinus system. A significant proportion of patients had raised D-dimer (75.0%) and CRP levels (50.0%). Two patients reported presence of antiphospholipid antibodies. Most patients received anticoagulation (91.7%) while overall mortality rate was 45.5%. CONCLUSIONS: The high mortality rate of CVT in COVID-19 infection warrants a high index of suspicion from physicians, and early treatment with anticoagulation should be initiated.

OBJECTIVE: The incidence of complications due to acute otitis media (AOM) in childhood has decreased significantly with the use of new antibiotics in recent years. However, acute mastoiditis (AM) is still the most common complication that can lead to further intracranial conditions with high morbidity. Our study aimed to evaluate the clinical characteristics of children with AM and identify possible indicators for further intracranial complications associated with this condition. METHODS: Children hospitalized in our clinic with a diagnosis of AM were reviewed. Demographic data, disease-related symptoms, types of complications accompanied by AM, medical/surgical treatments modalities, and culture results were screened. The patients were divided into two groups as those with and without intracranial complications (ICCs). Routine complete blood count tests, biochemical analysis, and C-reactive protein (CRP) level measurement were evaluated and compared between the groups. RESULTS: Of the 28 AM patients, five (17.9%) had isolated AM. Complications associated with AM included sub-periosteal abscess (28.6%), facial paralysis (25%), meningitis (17.9%), meningitis with sigmoid sinus thrombosis (7.1%), and meningitis with cerebellar abscess (3.6%). Eight patients developed ICCs (28.6%), of whom three had more than one complication. Ceftriaxone was found to be the first-line medical treatment (57.1%). Streptococcus pneumoniae was the most common pathogen isolated from the cultures (42.9%). Three patients (10.7%) were treated non-surgically, eight (28.6%) with myringotomy and ventilation tube (VT) insertion, eight patients (28.6%) with abscess drainage and VT insertion, and nine (32.1%) with cortical mastoidectomy and VT insertion. There was no significant difference between the patients with and without ICCs in terms of complete blood count parameters. The CRP level and the CRP-albumin ratio were significantly higher in patients with ICCs than those without these complications (p < 0.001). CONCLUSION: AM remains to be the most common complication of AOM in childhood and can lead to further life-threatening conditions. Additional interventions according to the type of the complication with VT insertion is safe and effective in the management of AM. In patients with AM, it is of great importance to determine whether there is an accompanying ICC. The CRP-albumin ratio is a simple and reliable calculation to detect ICCs in patients with AM.

OBJECTIVE: To evaluate the prognosis values of systemic immune-inflammation index (SII) in non-chronic cerebral venous sinus thrombosis (CVST). METHODS: patients with CVST, admitted to the First Affiliated Hospital of Zhengzhou University, were retrospectively identified from January 2013 to December 2018. We selected patients in acute/subacute phase from database. Functional outcomes of patients were evaluated with the modified Rankin Scale (mRS)-mRS 3-6 as poor outcomes and mRS 6 as death. The overall survival time was defined as the date of onset to the date of death or last follow-up date. Survival analysis was described by the Kaplan-Meier curve and Cox regression analysis. Multivariate logistic regression analysis assessed the relationship between SII and poor functional outcome. The area under the Receiver Operating Curve curve (AUC) was estimated to evaluate the ability of SII in prediction. RESULTS: A total of 270 patients were included and their duration of follow-up was 22 months (6-66 months), of whom 31 patients had poor outcomes and 24 patients dead. Cox regression analysis showed that SII (HR=1.304, 95% CI: 1.101 to 1.703, p=0.001) was a predictor of death in non-chronic CVST. Patients with higher SII presented lower survival rates (p=0.003). The AUC of SII was 0.792 (95% CI: 0.695 to 0.888, p=0.040) with a sensitivity of 69.6% and specificity of 80.1%. Subgroups analysis demonstrated that SII was an important predictor of poor outcomes in male (OR=1.303, 95% CI: 1.102 to 1.501, p=0.011) and pregnancy/puerperium female (OR=1.407, 95% CI: 1.204 to 1.703, p=0.034). CONCLUSIONS: SII was a potential predictor in the poor prognosis of patients with acute/subacute CVST, especially in male and pregnancy/puerperium female.

To collect and summarize pregnancy outcomes among women with a history of cerebral sinus vein thrombosis (CSVT). A retrospective multicenter case-control study. The study group comprised all women diagnosed with CSVT during 2004-2018 at four university hospitals, and with follow-up data of pregnancy. A control group of women with a singleton pregnancy was established by matching, four-to-one, according to maternal age. The data of 74 pregnancies of 65 women with CSVT were analyzed. The median time-to-pregnancy interval from the CSVT was 4.2 [2.7-6.8] years. Anticoagulation therapy in the form of enoxaparin was administered in 68 (91.9%) pregnancies. Adjunctive low-dose aspirin was used throughout 12 (16.2%) pregnancies. Overall, 54 (73.0%) of the pregnancies ended in live births and 20 (27.0%) in miscarriage. The use of anticoagulation therapy during pregnancy was positively associated with live birth outcome (P < 0.001). Late adverse outcomes were encountered in 19 (25.7%) pregnancies, including the delivery of a small for gestational age infant (n = 12), gestational hypertensive disorders (n = 6) and placental abruption (n = 3). The use of adjunctive aspirin was associated with a lower rate of late adverse pregnancy outcomes (P = 0.03). No recurrent CSVT, thrombosis at other sites, and major bleeding episodes were observed during pregnancy. Live-birth rate was higher (P = 0.007) and the rate of late adverse outcome was lower (P = 0.01) for the control (n = 296) than the study group. Among pregnant women with a prior CSVT, no recurrent thrombosis events were observed during gestation. The use of prophylactic anticoagulation was associated with live birth. The use of adjunctive aspirin should be further studied in this setting, as its utilization correlated with a lower rate of late pregnancy complications.

OBJECTIVE: An association between cerebral venous sinus thrombosis (CVST) and high altitude has been previously proposed, but limited published data exist to support this association. We investigated 28 cases of CVST occurring at high altitude and sought to describe patient demographics, altitude and acclimatization, hematological laboratory findings, neuroimaging, treatment, and prognosis in these cases. METHODS: Twenty-eight cases of symptomatic CVST occurring at high altitude were identified between the months of August 2017 and December 2018, in collaboration with Military Hospital, Rawalpindi and Combined Military Hospital, Skardu (Pakistan). Follow-up visits were performed at 1 and 6 months. RESULTS: Twenty-seven (96%) of the patients were males, and the mean age was 33 years. In total, 32.1% were smokers. The mean NIHSS score on presentation was 5.5. 85.7% of the cases occurred at altitude higher than 8,000 feet. On average 107.8 days were spent at a high altitude prior to CVST. Totally, 71.4% had acclimatized for >2 weeks. The mean hemoglobin (Hb) value was 16.7 g/dL and 50% had d-dimer levels higher than 1,000 ng/mL. On MRI, 25% showed signs of hemorrhage and 14.3% showed infarcts. Treatments provided include low-molecular-weight heparin and Rivaroxaban and were associated with good outcomes. CONCLUSION: CVST is not uncommon at high altitude (>8,000 feet). It is predominantly a male disease. Most patients have high Hb and high D-dimer levels. The overall outcome was good.

Background: Lymphocyte to monocyte ratio (LMR) is associated with functional outcome in patients with stroke. But the relationship between the LMR value and the prognosis of cerebral venous sinus thrombosis (CVST) has not been investigated. Methods: CVST patients, admitted to the First Affiliated Hospital of Zhengzhou University, were retrospectively identified from November 2010 to January 2017. Functional outcomes of patients were evaluated with the modified Rankin Scale (mRS). Patients were divided into good (mRS 0-2) and poor (mRS 3-6) outcomes groups. Univariate and multivariate Cox regression analyses were used to assess the relationship between LMR and the poor survival outcome. Results: A total of 228 patients were included of which 41 had poor outcomes (18.0%). The duration of follow-up was 22 months (6-66 months). LMR (2.3±1.2 vs 3.2±1.8, p<0.01) was significantly lower in the poor outcome group. Multivariate Cox regression analysis showed that LMR (HR 0.726, 95% CI 0.546 to 0.964, p=0.027) was a independent predictor of poor prognosis. Conclusions: LMR may be a predictor of poor prognosis in CVST patients.

Cerebral venous sinus thrombosis (CVST) requires anticoagulation to promote vessel recanalization. Current anticoagulation paradigms utilize plasma tests from peripheral venous/arterial samples for therapeutic monitoring. We describe a medically-refractory case of CVST in a 35-year-old woman later found to have JAK2 mutation and essential thrombocytosis. Despite therapeutic anticoagulation levels, worsening cerebral edema and progression to coma prompted endovascular treatment. Failed endovascular thrombectomy attempts led to placement of 2 separate indwelling microcatheters for continuous infusion of tissue plasminogen activator (tPA). Forty-hours of continuous-tPA in addition to systemic intravenous-heparin led to complete radiographic and clinical resolution of CVST. Whole blood coagulation testing using Rotational Thromboelastometry (ROTEM) from simultaneous samples taken intracranially (via cerebral microcatheters) and peripherally (via antecubital vein) all revealed prolonged intrinsic pathway activation clotting times consistent with heparin anticoagulation use. However, both intracranial ROTEM samples identified faster clotting times compared to the peripheral sample suggesting lower anticoagulation levels intracranially. Our findings were speculative and hypothesis generating as to whether this explained medical treatment failure. If there are coagulopathy differences at local sites of injury not adequately captured by peripheral blood draws, further investigation is required to identify better approaches to avoid under-treatment of similar cases.

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a recognized cause of childhood and neonatal stroke with high morbidity and mortality and a challenging diagnosis in the pediatric population. OBJECTIVE: We hypothesize that measuring Hounsfield units (HU) of blood in venous sinuses is a more reliable method to diagnose CVST and that normalizing the measured HU in relation to the patient's hematocrit levels may further improve detection of CVST in the pediatric population. MATERIALS AND METHODS: We performed a retrospective chart review of 15 pediatric patients with acute CVST and 31 control patients. Regions of interest (ROIs) were plotted to measure HU values within the venous sinuses of each patient. Hounsfield unit to hematocrit (HU:Hct) ratios were also calculated. In patients with CVST, HU values were determined in thrombosed and non-thrombosed venous sinuses. Statistical analysis was performed to calculate the differences between patient and control groups and to determine optimal cutoff values for HU and HU:Hct measurements in diagnosing CVST on non-contrast brain computed tomography (CT). RESULTS: A statistically significant difference in sinus attenuation and HU:Hct ratio was found between thrombosed (66.2±5.3 HU, 1.96±0.4) and non-thrombosed sinuses (47.2±4.5 HU, 1.38±0.25) in the patient group (P<0.0001), with the average attenuation difference being 19 HU. A statistically significant difference was also found between thrombosed sinuses in the patient group and sinuses (48.9±3.13 HU, 1.3±0.12) in the control group (P<0.0001). CONCLUSION: Optimal cutoff values of 58 HU and HU:Hct ratios of 1.4 lead to sensitivities of 100% in diagnosing CVST.

The cerebral venous system is an unusual site of thrombosis, with a particularly high incidence in young adults. This incidence has increased in past decades because of the improvement of neuroradiological techniques. Risk factors for cerebral venous sinus thrombosis overlap with those of other venous thromboembolism sites; however, some are specific for this particular anatomical district. Prognosis is favorable in most cases if diagnosis is made rapidly and treatment is promptly initiated, even if acute complications or chronic invalidity still occur in a quarter of patients. The mainstay of treatment is anticoagulation, which is necessary in order to block clot propagation and obtain recanalization. Intracranial bleeding does not contraindicate anticoagulation. Endovascular procedures are reserved for patients with a particularly severe presentation or rapidly declining neurological symptoms despite appropriate anticoagulation, although data from clinical trials are lacking. Specifically, this review addresses the epidemiology, clinical presentation and course, risk factors, and treatment of cerebral venous sinus thrombosis, with a special focus on the pediatric population.
