Intracranial hypertension after cerebral venous thrombosis-Risk factors and outcomes.

ABSTRACT:

Background and purpose

Cerebral venous thrombosis (CVT) is a special cerebrovascular disease that accounts for around 0.5%-1.0% of all strokes and often occurs in younger adults. Intracranial hypertension is the most frequent symptom of acute CVT due to venous occlusion. This study aimed to ascertain the risk factors for intracranial hypertension after CVT and to investigate whether intracranial hypertension at diagnosis may affect patient outcomes.

Methods

We performed a retrospective cohort analysis of all patients treated for acute/subacute CVT at our department between 2018 and 2021. Logistic regression analysis was performed to identify potential risk factors associated with intracranial hypertension after CVT and clinical outcomes at the 6-month follow-up.

Results

A total of 293 acute/subacute CVT survivors were eligible for inclusion, with 245 patients (83.60%) experiencing concomitant intracranial hypertension at diagnosis. In the multivariable regression analysis, hereditary thrombophilia (OR 2.210, 95% CI 1.148-4.254, p = 0.018) and thrombosis location of superior sagittal sinus (SSS) and right lateral sinus (LS) (OR 4.115, 95% CI 1.880-9.010, p = 0.000) were independently associated with intracranial hypertension. 83.67% of patients with intracranial hypertension after CVT had favorable functional outcomes (mRS score, 0-2), whereas they more often had residual visual impairment (15.51% vs. 4.17%, p = 0.036) at follow-up. The risk factors for residual visual impairment were papilledema (OR 2.971, 95% CI 1.231-7.170, p = 0.015) and visual disturbances at diagnosis (OR 2.869, 95% CI 1.123-7.327, p = 0.028), thrombosis location (SSS and right LS [OR 10.811, 95% CI 4.208-27.773, p = 0.000]; SSS and left LS [OR 3.139, 95% CI 1.409-6.995, p = 0.005]), and CVT recurrence (OR 4.763, 95% CI 1.556-14.584, p = 0.006).

Conclusions

Intracranial hypertension is the most common clinical symptom of acute CVT. At follow-up, patients with intracranial hypertension after CVT were more prone to develop residual visual impairment.

Project description:PurposeTo evaluate the alteration of pressure characteristics in the cerebral venous sinuses before and after venous sinus stenting (VSS) using mean sinus pressures (MSPs), sinus pressure gradient (SPG), and sinus pressure pulsatility (SPP) parameters among the idiopathic intracranial hypertension (IIH) patients.Materials and methodsProspective evaluation of 45 consecutive IIH patients who underwent VSS at our institution. A written informed consent approved by the Weill Cornell Institutional Review Board was signed by the study participants. All patients (n = 45) were evaluated for MSPs and SPG. In a subgroup of 12 (n = 12) consecutive patients, SPP was measured. MSP was measured using microcatheter at superior sagittal sinus (SSS), transverse sinus (TS), and sigmoid sinus (SS). SPG was measured as trans-stenotic gradient and trans-torcular gradient. SPP was recorded in the dominant TS with a six French intermediate catheter. Statistical analysis was performed using paired student t-test and two sample t-tests tested for both equal and unequal variances. P values below 0.05 were considered significant.ResultsThe mean age of the study population was 30.6 ± 10 years (7-59 years) and 43 out of 45 are female patients. The mean weight and BMI of the study population were 96 ± 24.7 kg (30.8-144 kg) and 35.6 ± 8.3 kg/M2 (16.4-51.4 kg/M2), respectively. VSS in IIH patients resulted in immediate reduction of MSP in the SSS {Δ Mean: -8.1 mm Hg [95% confidence interval (CI): -5.0-11.7 mm Hg], p < 0.001} and TS [Δ Mean: -11.8 mm Hg (95% CI: -7.5 to 13.4 mm Hg), p < 0.001] and increase of MSP in SS [Δ Mean: 7.5 mm Hg (95% CI: 6-10.1 mm Hg), p < 0.001]. Significant reduction of trans-stenotic SPG reduction [Δ Mean: -15.7 mm Hg (95% CI: -13.6-17.8 mm Hg), p < 0.001] and SPP [Δ Mean: -8 mm Hg (95% CI: -2.5-13.4 mm Hg), p < 0.05] was observed following VSS.ConclusionVSS resulted in immediate alteration of the cerebral venous sinus pressure measurements in patients with IIH.

Project description:PurposeMagnetic resonance venography (MRV) has not been validated in pre-operative planning of the dural venous sinus stenting (VSS) among idiopathic intracranial hypertension (IIH) patients. We aim to prospectively evaluate dural venous sinus measurement in IIH patient population on two-dimensional time-of-flight (2D-TOF) MRV and Three-dimensional contrast-enhanced (3D-CE) MRV acquisitions and compare them against real-time endoluminal measurements with intravascular ultrasound (IVUS), served as the reference.Materials and methodsThe study has been approved by the Weill Cornell Medicine institutional review board. All patients signed written informed consent approved by IRB. Prospective evaluation of forty-five consecutive IIH patients treated with VSS at our institution were evaluated. Patients with pre-stent magnetic resonance venography (MRV) ≤ 6-months of VSS and intravascular ultrasound (IVUS) during VSS constituted the study population. Maximum diameter (in mm), Area (in cm2) and Perimeter (in cm) were measured at posterior 1/3rd of superior sagittal sinus (SSS), proximal transverse sinus (PTS), proximal sigmoid sinus (PSS) and mid sigmoid sinus (MSS) on 2D-TOF-MRV, 3D-CE-MRV and IVUS. Statistical analysis performed using box and whisker plots, Bland-Altman analysis and paired sample t-test.ResultsTwenty (n = 20) patients constituted our study population. The mean age was 30±11 years (7-59 years) and 18 out of 20 were female patients. Mean weight and BMI (range) were 86.3±18.3 kilograms (30.8-107.5 kgs) and 32.9±6.8 kg/M2 (16.4-48.3kg/M2) respectively. The CE-MRV significantly oversized the cerebral venous sinuses compared to TOF-MRV (Dmax: +2.0±1.35 mm, p<0.001; Area: +13.31±10.92 mm2, p<0.001 and Perimeter: +4.79±3.4 mm, p<0.001) and IVUS (Dmax: +1.52±2.16 mm, p<0.001; Area: +10.03±21.5 mm2, p<0.001 and Perimeter: +4.15±3.27 mm, p<0.001). The TOF-MRV sinus measurements were in good agreement with the IVUS measurements with no significant variation (Dmax: +.21±2.23 mm, p = 0.49; Area: +2.51±20.41mm2, p = 0.347 and Perimeter: +.001±1.11 mm, p = 0.991).ConclusionWe report baseline cerebral venous sinus measurements (maximum diameter, area and perimeter) in patients with idiopathic intracranial hypertension. In our experience, TOF-MRV is a reliable representation of endoluminal cerebral venous sinus dimensions, and CE-MRV measurements reflected an overestimation of the endoluminal sinus dimensions when compared against the real time IVUS measurements.

Project description:BackgroundCerebral venous sinus thrombosis is a rare stroke with several clinical manifestations. Several studies have identified prognostic risk factors associated with poor functional outcomes and established predictive models. This systematic review and meta-analysis assessed the overall effect size of all prognostic risk factors.MethodsA systematic review was conducted to explore all prognostic risk factors in studies published from the initial to June 2024 among 5 Databases included PubMed / Medline, Scopus, EBSCOhost, Web of Science, and Cochran Library. The quality of the methodology was analyzed using the Newcastle-Ottawa Scale. Data analysis was performed using the Statistical Package for Social Sciences (SPSS) version 29.ResultsSixty-four studies involving 18,958 participants with a mean age of 38.46 years and females 63.03% were included in the quantitative meta-analysis. Functional outcomes were primarily measured using the Modified Rankin Scale (mRS), with scores ≥ 2 or ≥ 3 indicating poor outcomes in 35.00% and 60.00% of studies, respectively. For general information, age (InOR = 0.98, 95% CI 0.53-1.43), intracranial hemorrhage (OR = 3.79, 95% CI 2.77-5.20), and ischemic infarction (OR = 3.18, 95% CI 2.40-4.23) were associated with poor functional outcomes. For general and neurological symptoms, headache (OR = 0.22, 95% CI 0.17-0.29), seizure (OR = 2.74, 95% CI 1.76-4.27), focal deficit (OR = 4.72, 95% CI 3.86-5.78), coma (OR = 11.60, 95% CI 6.12-21.98), and consciousness alteration (OR = 7.07, 95% CI 4.15-12.04) were outstanding factors. The blood biomarkers of NLR (log OR = 1.72, 95% CI 0.96-2.47), lymphocytes (Cohen's d = -0.63, 95 CI -0.78--0.47), and D-dimer (lnOR = 1.34, 95% CI 0.87-1.80) were the three most frequently reported factors. Parenchymal lesion (OR = 4.71, 95% CI 1.12-19.84) and deep cerebral venous thrombosis (OR = 6.30, 95% CI 2.92-13.63) in radiological images were two frequently reported factors. CVST patients with cancer (OR = 3.87, 95% CI 2.95-5.07) or high blood glucose levels (OR = 3.52, 95% CI 1.61-7.68) were associated with poor functional outcomes. In the meta-regression analysis, ischemic infarction (P = 0.032), consciousness alteration (P < 0.001), and NLR (P = 0.015) were associated with mRS prediction.ConclusionsPooled effect sizes revealed that ischemic infarction, headache, neurological focal deficit, lymphopenia, and cancer were significantly associated with poor functional outcomes, with low to moderate heterogeneity. Consciousness alterations/deterioration and deep cerebral venous thrombosis were also significant prognostic factors, albeit with substantial heterogeneity. The meta-regression analysis showed that the effect sizes of consciousness alterations/deterioration and NLR increased with worsening mRS scores. Other notable risk factors included age, intracranial hemorrhage, seizures, coma, D-dimer, parenchymal lesions, and hyperglycemia. This systematic review provides a comprehensive overview of the prognostic risk factors for poor functional outcomes in patients undergoing CVST, which can guide clinical decision-making and future research.Trial registrationThis systematic review and meta-analysis has been registered with INPLASY (International Platform of Registered Systematic Review and Meta-analysis Protocols), and the registration number is INPLASY202480072. The registration period is 14 August 2024.
