RESUMEN

Objective: Investigate the potential correlation between the age of initial sexual contact, the lifetime accumulation of sexual partners, and the occurrence of intracranial aneurysm (IA) employing a two-sample Mendelian randomization approach. Methods: This research aims to elucidate the causal relationship between intracranial aneurysm (IA) and sexual variables. Two distinct sexual variables, specifically the age had first sexual intercourse (n = 406,457) and the lifetime number of sexual partners (n = 378,882), were employed as representative parameters in a two-sample Mendelian randomization (MR) study. Outcome data from 23 cohorts, comprising 5,140 cases and 71,934 controls, were gathered through genome-wide association studies (GWAS). To bolster analytical rigor, five distinct methodologies were applied, encompassing MR-Egger technique, weighted median, inverse variance weighted, simple modeling, and weighted modeling. Results: Our investigation unveiled a causal relationship between the age first had sexual intercourse and the occurrence of intracranial aneurysm (IA), employing the Inverse Variance Weighted (IVW) approach [Odds Ratio (OR): 0.609, p-value: 5.684E-04, 95% Confidence Interval (CI): 0.459-0.807]. This association was notably significant in the context of unruptured intracranial aneurysms (uIA) using the IVW approach (OR: 0.392, p-value: 6.414E-05, 95% CI: 0.248-0.621). Conversely, our findings did not reveal any discernible link between the lifetime number of sexual partners and the occurrence of IA (IA group: OR: 1.346, p-value: 0.415, 95% CI: 0.659-2.749; SAH group: OR: 1.042, p-value: 0.943, 95% CI: 0.338-3.209; uIA group: OR: 1.990, p-value: 0.273, 95% CI: 0.581-6.814). Conclusion: The two-sample Mendelian Randomization (MR) study presented herein provides evidence supporting a correlation between the age of initial engagement in sexual activity and the occurrence of intracranial aneurysm (IA), with a noteworthy emphasis on unruptured intracranial aneurysms (uIA). Nevertheless, our investigation failed to establish a definitive association between IA and the cumulative lifetime number of sexual partners.

RESUMEN

BACKGROUND: The risk of intracranial aneurysms (IAs) is increased in individuals with depression and anxiety. This indicates that depression and anxiety may contribute to the development of physical disorders. Herein, to investigate the association between genetic variants related to depression and anxiety and the risk of IA, two-sample Mendelian randomization was performed. METHODS: The genome-wide association study (GWAS) comprised genome-wide genotype data of 2248 clinically well-characterized patients with anxiety and 7992 ethnically matched controls from four European countries. Sex-specific summary-level outcome data were obtained from the GWAS of IA, including 23 cohorts with a total of 10,754 cases and 306,882 controls of European and East Asian ancestry. To improve validity, five varying Mendelian randomization techniques were used in the analysis, namely Mendelian randomization-Egger, weighted median, inverse variance weighted, simple mode, and weighted mode. RESULTS: The inverse variance weighted results indicated the causal effect of depression on IA (P = 0.03, OR = 1.32 [95 % CI, 1.03-1.70]) and unruptured IA (UIA) (P = 0.02, OR = 1.68 [95 % CI, 1.08-2.61]). However, the causal relationship between depression and subarachnoid hemorrhage (SAH) was not found (P = 0.16). We identified 43 anxiety-associated single-nucleotide polymorphisms as genetic instruments and found no causal relationship between anxiety and IA, UIA, and SAH. LIMITATIONS: Potential pleiotropy, possible weak instruments, and low statistical power limited our findings. CONCLUSION: Our MR study suggested a possible causal effect of depression on the increased risk of UIAs. Future research is required to investigate whether rational intervention in depression treatment can help to decrease the societal burden of IAs.

RESUMEN

Autophagy is considered a double-edged sword, with a role in the regulation of the pathophysiological processes of the central nervous system (CNS) after cerebral ischemia-reperfusion injury (CIRI). The 18-kDa translocator protein (TSPO) is a highly conserved protein, with its expression level in the nervous system closely associated with the regulation of pathophysiological processes. In addition, the ligand of TSPO reduces neuroinflammation in brain diseases, but the potential role of TSPO in CIRI is largely undiscovered. On this basis, we investigated whether TSPO regulates neuroinflammatory response by affecting autophagy in microglia. In our study, increased expression of TSPO was detected in rat brain tissues with transient middle cerebral artery occlusion (tMCAO) and in BV2 microglial cells exposed to oxygen-glucose deprivation or reoxygenation (OGD/R) treatment, respectively. In addition, we confirmed that autophagy was over-activated during CIRI by increased expression of autophagy activation related proteins with Beclin-1 and LC3B, while the expression of p62 was decreased. The degradation process of autophagy was inhibited, while the expression levels of LAMP-1 and Cathepsin-D were significantly reduced. Results of confocal laser microscopy and transmission electron microscopy (TEM) indicated that autophagy flux was disordered. In contrast, inhibition of TSPO prevented autophagy over-activation both in vivo and in vitro. Interestingly, suppression of TSPO alleviated nerve cell damage by reducing reactive oxygen species (ROS) and pro-inflammatory factors, including TNF-α and IL-6 in microglia cells. In summary, these results indicated that TSPO might affect CIRI by mediating autophagy dysfunction and thus might serve as a potential target for ischemic stroke treatment.

RESUMEN

PURPOSE: Intracranial vertebral artery dissecting aneurysm (IVADA) is a rare type of aneurysm with high morbidity and mortality. Recently, the application of pipeline embolization devices (PEDs) has been extended to IVADAs. Here, we aim to investigate the safety and effectiveness of PEDs for IVADAs. METHOD: We retrospectively reviewed the PLUS database to identify patients who had IVADAs and were treated with PEDs from 2014 to 2019 at 14 centers across China. Data including patient and aneurysm characteristics, procedure details, angiographic and clinical results, relationship with the ipsilateral posterior inferior cerebellar artery (PICA), and patency of the PICA following PED coverage were analyzed. RESULTS: In this study 52 consecutive patients with 52 IVADAs were included. The mean age was 52.33 years and 82.7% were male. With a median follow-up of 10.5 months, the complete occlusion rate was 93.8% (45/48) and no recurrence or in-stent stenosis was detected. The total postoperative complication rate and mortality were 11.5% and 1.9%, respectively. Complications occurred in 9.6% (5/52) of patients within 30 days after the operation, including ischemic stroke in 3 and hemorrhagic stroke in 2. Another patient suffered an ischemic stroke at follow-up, 78.8% (41/52) PICAs were covered by PEDs, 1 case (2.4%) had a functional disability due to PICA occlusion, while 39.0% (16/41) had reduced flow during follow-up but hardly caused any obvious neurological deficits. Patients with IVADA involving PICA had a trend towards more complications (66.7% vs. 51.1%; P = 1). CONCLUSION: Treating IVADAs with PEDs may be a safe and effective option, with favorable clinical and angiographic outcomes; however, complications associated with this treatment should not be ignored.

RESUMEN

Background: Immunogenic Cell Death (ICD) is a novel way to regulate cell death and can sufficiently activate adaptive immune responses. Its role in immunity is still emerging. However, the involvement of ICD in Intracranial Aneurysms (IA) remains unclear. This study aimed to identify biomarkers associated with ICDs and determine the relationship between them and the immune microenvironment during the onset and progression of IA. Methods: The IA gene expression profiles were obtained from the Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) in IA were identified and the effects of the ICD on immune microenvironment signatures were studied. Techniques like Lasso, Bayes, DT, FDA, GBM, NNET, RG, SVM, LR, and multivariate analysis were used to identify the ICD gene signatures in IA. A consensus clustering algorithm was used for conducting the unsupervised cluster analysis of the ICD patterns in IA. Furthermore, enrichment analysis was carried out for investigating the various immune responses and other functional pathways. Along with functional annotation, the weighted gene co-expression network analysis (WGCNA), protein-protein interaction (PPI) network and module construction, identification of the hub gene, and co-expression analysis were also carried out. Results: The above techniques were used for establishing the ICD gene signatures of HMGB1, HMGN1, IL33, BCL2, HSPA4, PANX1, TLR9, CLEC7A, and NLRP3 that could easily distinguish IA from normal samples. The unsupervised cluster analysis helped in identifying three ICD gene patterns in different datasets. Gene enrichment analysis revealed that the IA samples showed many differences in pathways such as the cytokine-cytokine receptor interaction, regulation of actin cytoskeleton, chemokine signaling pathway, NOD-like receptor signaling pathway, viral protein interaction with the cytokines and cytokine receptors, and a few other signaling pathways compared to normal samples. In addition, the three ICD modification modes showed obvious differences in their immune microenvironment and the biological function pathways. Eight ICD-regulators were identified and showed meaningful associations with IA, suggesting they could severe as potential prognostic biomarkers. Conclusions: A new gene signature for IA based on ICD features was created. This signature shows that the ICD pattern and the immune microenvironment are closely related to IA and provide a basis for optimizing risk monitoring, clinical decision-making, and developing novel treatment strategies for patients with IA.

RESUMEN

BACKGROUND: In-stent stenosis (ISS) is a delayed complication that can occur after pipeline embolization device use when treating intracranial aneurysms (IAs). OBJECTIVE: To assess the incidence, predictors, and outcomes of ISS. METHODS: This was a retrospective, multicenter, observational study. All patient data were collected from a PLUS registry study. We collected data from patients with IA who completed digital subtraction angiography at follow-up and divided patients into "non-ISS," "mild ISS," or "severe ISS" groups. Multivariate logistic regression analysis was conducted to determine predictors of ISS. RESULTS: A total of 1171 consecutive patients with 1322 IAs participated in this study. Angiographic follow-up was available for 662 patients with 728 IAs, and the mean follow-up time was 9 months. ISS was detected in 73 cases (10.03%), including 61 mild ISS cases and 12 severe ISS cases. Univariate and multivariable analysis demonstrated that current smoking history (mild ISS: OR 2.15, 95% CI 1.122-4.118, P = .021; severe ISS: OR 5.858, 95% CI 1.186-28.93, P = .030) and cerebral atherosclerosis (mild ISS: OR 5.694, 95% CI 3.193-10.15, P = .001; severe ISS: OR 6.103, 95% CI 1.384-26.91, P = .017) were independent predictors of ISS. Compared with the other groups, the severe ISS group had higher rate of ischemic stroke (33.3%). CONCLUSION: ISS occurs in approximately 10.03% of cases at a mean follow-up of 9 months. Statistically, current smoking history and cerebral atherosclerosis are the main predictors of ISS. Severe ISS may be associated with higher risk of neurological ischemic events in patients with IA after pipeline embolization device implantation.

RESUMEN

OBJECTIVE: In this study, the hemodynamic parameters of ruptured intracranial aneurysms (IAs) in various studies were summarized and analyzed to provide predictive parameters for IA rupture in clinical work. METHODS: We searched PubMed, Web of science, Embase, and Cochrane databases for articles published before December 2021 to collect data on hemodynamic parameters associated with IA rupture. Differences in wall shear stress (WSS), oscillatory shear index (OSI), and low wall shear stress area (LSA) between ruptured and unruptured IAs in the literature were summarized and analyzed, and the standardized mean difference (SMD) of 95% CI was calculated by Review Manager 5.3. RESULTS: By searching and screening the literature, this meta-analysis included 17 studies comprising 1,373 IA patients. In the ruptured aneurysm group, the level of WSS decreased significantly, while OSI and LSA increased obviously. CONCLUSION: Low WSS, high OSI, and high LSA are closely related to the rupture of IAs, indicating the role of WSS, OSI, and LSA as important hemodynamic parameters for predicting the rupture of IAs in clinical work.

RESUMEN

Background: The role of epigenetic modulation in immunity is receiving increased recognition-particularly in the context of RNA N6-methyladenosine (m6A) modifications. Nevertheless, it is still uncertain whether m6A methylation plays a role in the onset and progression of intracranial aneurysms (IAs). This study aimed to establish the function of m6A RNA methylation in IA, as well as its correlation with the immunological microenvironment. Methods: Our study included a total of 97 samples (64 IA, 33 normal) in the training set and 60 samples (44 IA, 16 normal) in the validation set to systematically assess the pattern of RNA modifications mediated by 22 m6A regulators. The effects of m6A modifications on immune microenvironment features, i.e., immune response gene sets, human leukocyte antigen (HLA) genes, and infiltrating immune cells were explored. We employed Lasso, machine learning, and logistic regression for the purpose of identifying an m6A regulator gene signature of IA with external data validation. For the unsupervised clustering analysis of m6A modification patterns in IA, consensus clustering methods were employed. Enrichment analysis was used to assess immune response activity along with other functional pathways. The identification of m6A methylation markers was identified based on a protein-protein interaction network and weighted gene co-expression network analysis. Results: We identified an m6A regulator signature of IGFBP2, IGFBP1, IGF2BP2, YTHDF3, ALKBH5, RBM15B, LRPPRC, and ELAVL1, which could easily distinguish individuals with IA from healthy individuals. Unsupervised clustering revealed three m6A modification patterns. Gene enrichment analysis illustrated that the tight junction, p53 pathway, and NOTCH signaling pathway varied significantly in m6A modifier patterns. In addition, the three m6A modification patterns showed significant differences in m6A regulator expression, immune microenvironment, and bio-functional pathways. Furthermore, macrophages, activated T cells, and other immune cells were strongly correlated with m6A regulators. Eight m6A indicators were discovered-each with a statistically significant correlation with IA-suggesting their potential as prognostic biological markers. Conclusion: Our study demonstrates that m6A RNA methylation and the immunological microenvironment are both intricately correlated with the onset and progression of IA. The novel insight into patterns of m6A modification offers a foundation for the development of innovative treatment approaches for IA.

RESUMEN

Background: DNA methylation is an important epigenetic modification that affects genomic instability and regulates gene expression. Long non-coding RNAs (lncRNAs) modulate gene expression by interacting with chromosomal modifications or remodelling factors. It is urgently needed to evaluate the effects of DNA methylation-related lncRNAs (DMlncRNAs) on genome instability and further investigate the mechanism of action of DMlncRNAs in mediating the progression of lower-grade gliomas (LGGs) and their impact on the immune microenvironment. Methods: LGG transcriptome data, somatic mutation profiles and clinical features analysed in the present study were obtained from the CGGA, GEO and TCGA databases. Univariate, multivariate Cox and Lasso regression analyses were performed to establish a DMlncRNA signature. The KEGG and GO analyses were performed to screen for pathways and biological functions associated with key genes. The ESTIMATE and CIBERSORT algorithms were used to determine the level of immune cells in LGGs and the immune microenvironment fraction. In addition, DMlncRNAs were assessed using survival analysis, ROC curves, correlation analysis, external validation, independent prognostic analysis, clinical stratification analysis and qRT-PCR. Results: We identified five DMlncRNAs with prognostic value for LGGs and established a prognostic signature using them. The Kaplan-Meier analysis revealed 10-years survival rate of 10.10% [95% confidence interval (CI): 3.27-31.40%] in high-risk patients and 57.28% (95% CI: 43.17-76.00%) in low-risk patients. The hazard ratio (HR) and 95% CI of risk scores were 1.013 and 1.009-1.017 (p < 0.001), respectively, based on the univariate Cox regression analysis and 1.009 and 1.004-1.013 (p < 0.001), respectively, based on the multivariate Cox regression analysis. Therefore, the five-lncRNAs were identified as independent prognostic markers for patients with LGGs. Furthermore, GO and KEGG analyses revealed that these lncRNAs are involved in the prognosis and tumorigenesis of LGGs by regulating cancer pathways and DNA methylation. Conclusion: The findings of the study provide key information regarding the functions of lncRNAs in DNA methylation and reveal that DNA methylation can regulate tumour progression through modulation of the immune microenvironment and genomic instability. The identified prognostic lncRNAs have high potential for clinical grouping of patients with LGGs to ensure effective treatment and management.

RESUMEN

Autophagy is a highly conserved lysosomal degradation process essential in tumorigenesis. However, the involvement of autophagy-related long noncoding RNAs (lncRNAs) in low-grade glioma (LGG) remains unclear. In this study, we established an autophagy-related lncRNA prognostic signature for patients with LGG and assess its underlying functions. We used univariate Cox, least absolute shrinkage and selection operator and multivariate Cox regression models to establish an autophagy-related lncRNA prognostic signature. Kaplan-Meier survival analysis, receiver operating characteristic curve, nomogram, C-index, calibration curve and clinical decision-making curve were used to assess the predictive capability of the identified signature. A signature comprising nine autophagy-related lncRNAs (AL136964.1, ARHGEF26-AS1, PCED1B-AS1, AS104072.1, PRKCQ-AS1, LINC00957, AS125616.1, PSMB8-AS1 and AC087741.1) was identified as a prognostic model. Patients with LGG were divided into the high- and low-risk cohorts based on the median model-based risk score. The survival analysis revealed a 10-year survival rate of 9.3% (95% CI 1.91-45.3%) and 13.48% (95% CI 4.52-40.2%) in high-risk patients in the training and validation sets, respectively, and 48.4% (95% CI 24.7-95.0%) and 48.4% (95% CI 28.04-83.4%) in low-risk patients in the training and validation sets, respectively. This finding suggested a relatively low survival in high-risk patients. In addition, the lncRNA signature was independently prognostic and potentially associated with the progression of LGG. Therefore, the 9-autophagy-related-lncRNA signature may play a crucial role in the diagnosis and treatment of LGG, which may offer new avenues for tumour-targeted therapy.

RESUMEN

Objective:To investigate the efficacy and safety of endovascular recanalization in the treatment of chronically occluded internal carotid artery (COICA).Methods:From January 2014 to January 2019, patients over 50 years of age with symptomatic COICA underwent endovascular recanalization in the Department of Neurosurgery of the First Affiliated Hospital of Xinjiang Medical University were enrolled retrospectively. The modified Rankin Scale (mRS) was used to evaluate the improvement of neurological function.Results:A total of 19 patients with symptomatic COICA were enrolled, of which 16 (84.21%) were successfully recanalized. None of the patients had severe neurological deficits during the periprocedural period and after procedure. The neurological function of patients with successful recanalization gradually improved over time. The neurological function improved in 4 patients (25.0%) at 24 h after endovascular treatment and 9 (56.3%) at 18 months postprocedural follow-up. The follow-up of CT angiography showed that the internal carotid artery in patients with successful recanalization was unobstructed, and there was no obvious in-stent stenosis.Conclusion:Endovascular recanalization is feasible, safe and effective in patients with symptomatic COICA.

RESUMEN

Objective:To investigate the correlation between serum cystatin C (CysC), blood lipids and the risk of intracranial aneurysm (IA) rupture.Methods:Patients with saccular IA admitted to the First Affiliated Hospital of Xinjiang Medical University from December 2017 to May 2019 were enrolled retrospectively. The patients were divided into the ruptured group and the unruptured group. The correlation between CysC, lipids and IA rupture was identified by univariate and multivariate logistic regression analyses. Results:A total of 392 patients were enrolled, including 143 (36.5%) males and 249 (63.5%) females. Two hundred and seventy-eight patients (70.9%) were ruptured IAs, 114 (29.1%) were unruptured IAs. Univariate analysis showed that triglyceride (1.26±0.94 mmol/L vs. 2.12±1.45 mmol/L; t=5.872, P<0.001), apolipoprotein A-Ⅰ (0.95±0.29 g/L vs. 1.08±0.34 g/L; t=3.744, P<0.001 ), CysC (0.63±0.20 mg/L vs. 0.80±0.48 mg/L; t=3.650, P<0.001) level, and the proportions of hypertension (46.8% vs. 61.4%; χ2=6.938, P=0.008), hyperlipidemia (19.4% vs. 48.2%; χ2=32.493, P<0.001) and aneurysm diameter >7 mm (24.4% vs. 41.2%; χ2=11.504, P<0.001) of the ruptured group were significantly lower than those of the unruptured group, while the level of apolipoprotein B was significantly higher than that of the unruptured group (1.07±0.29 g/L vs. 0.99±0.30 g/L; t=2.417, P=0.016). Multivariate logistic regression analysis showed that aneurysm diameter ≤7 mm (odds ratio [ OR] 2.281, 95% confidence interval [ CI] 1.342-3.876; P=0.002), and the serum levels of triacylglycerol ( OR 0.484, 95% CI 0.333-0.705; P<0.001), apolipoprotein A-Ⅰ ( OR 0.248, 95% CI 0.105-0.587; P=0.002) and CysC ( OR 0.130, 95% CI 0.038-0.444; P=0.001) were significantly independently correlated with the risk of IA rupture. Conclusions:CysC, apolipoprotein A-Ⅰ and triacylglycerol are protective markers for IA rupture, and aneurysm diameter ≤7 mmis associated with IA rupture.

RESUMEN

INTRODUCTION: Lymphangioleiomyomatosis (LAM) is a rare disease which affects women of reproductive age almost exclusively as one of the most gender-specific diseases, and which can occur at any site in the body but most commonly in the lungs. Here we report a rare case of recurrent brain lymphangiomyoma which was misdiagnosed as angiomyxoma. CASE PRESENTATION: A 28-year-old male complained of finding a recurrent mass at the right temporal lobe of his brain for the last 4 months. He had undergone a resection of a brain mass two years prior. One year after the operation, the mass recurred again and was resected another time. Both of the operations were performed in another hospital and he was postoperatively diagnosed with angiomyxoma. This time the patient underwent a third operation in our hospital to remove the lesion, which was confirmed as lymphangiomyoma. Unfortunately, the patient again discovered a re-emerging mass at the primary operation site on the 50th day post-surgically. CONCLUSION: There is currently no effective cure for LAM and treatment options and relevant literature remain limited. Hence other potential therapeutic targets need to be identified.

RESUMEN

BACKGROUND: The purpose of this study is to report the treatment approaches and postoperative outcomes of extracranial carotid artery aneurysms (ECAAs) and discuss the symptoms, related risk factors, etiology, diagnostic methods, treatments, and follow-up period complications. CASE PRESENTATION: We describe three patients with symptomatic extracranial carotid artery aneurysms; one of them was treated with end-to-end anastomosis of the extracranial internal carotid artery (EICA) after the resection of the aneurysm, while the other two patients were deployed with Willis covered stents in the extracranial internal carotid artery. All of the patients were in good condition when discharged home. After a mean follow-up period of 8 months, all the patients were alive and only one of them had the neurologic deficit. Additionally, we reviewed the relative literatures. CONCLUSION: Both of the surgical and endovascular treatments have relatively satisfactory outcomes in ECAA patients. However, it is necessary to provide individualized treatments to different patients according to the characteristics of the aneurysms.

RESUMEN

Objective To investigate the predictive factors of short-term poor outcome in patients with cerebral venous sinus thrombosis (CVST).Methods The clinical data of 42 consecutive inpatients with CVST were analyzed retrospectively.The clinical outcomes were assessed with the modified Rankin scale (mRS) at discharge.The patients were divided into either a good outcome group (mRS 0 to 2) or a poor outcome group (mRS 3 to 6).The related factors,such as demographic,etiology,and clinical features were compared between the two groups,Multivariate logistic regression analysis was used to determine the independent predictive factors for short-term poor outcome in patients with CVST.Results A total of 42 patients with CVST were enrolled,29 of them (69.05％) had good outcome and 13 (30.95％) had poor outcome.The proportions of central nervous system infections (20.69％ vs.61.54％ ; x2 =6.740,P =0.009),cancer (6.90％ vs.38.46％ ;x2 =6.439,P =0.011),pregnancy,postpartum,oral contraceptives or hormone replacement therapy (6.90％ vs.38.46％ ; x2 =6.439,P =0.011),and high homocysteine hyperlipidemia (27.59％ vs.76.92％ ;x2 =8.922,P =0.003),as well as the baseline D-dimer levels (730 ± 240 ng/ml vs.1 060 ± 250 ng/ml; t =4.485,P =0.000) in patients of the good outcome group were significantly lower than those of the poor outcome group.There was significant difference in treatment modalities (x2 =11.274,P =0.004) with the poor outcome group.The proportions of patients in anticoagulants,thrombolysis and anticoagulants + thrombolysis were 13.79％,24.14％,and 62.07％,respectively,in the good outcome group,while those were 61.54％,23.08％,and 15.39％,respectively,in the poor outcome group.Multivariate logistic regression analysis showed that the baseline D-dimer level ＞990 ng/mL was an independent predictive factor for short-term poor outcome in patients with CVST (odds ratio [OR] 1.006,95％ confidence interval [CI] 1.002-1.011; P=0.005).Anticoagulants + thrombolytic therapy was an independent protective factor for short-term poor outcome in patients with CVST (OR 0.027,95％ CI 0.002-0.447; P=0.033).The ROC curve analysis showed that when the cutoff value of the baseline D-dimer was 990 ng/ml,the sensitivity and specificity of predicting short-term poor outcome of CVST were 76.9％ and 86.2％ respectively.Conclusions The level of baseline D-dimer ＞990 ng/ml is an independent predictive factor for short-term poor outcomes in patients with CVST.The effect of anticoagulants in combination with thrombolytic therapy is best in patients with CVST.
