Cerebral venous thrombosis(CVT)is a rare condition that can be fatal in severe cases.The limited occurrence of CVT poses challenges in conducting randomized controlled trials,leading to uncertainty regarding the effectiveness of endovascular thrombectomy(EVT)in specific subgroups of patients with CVT.Currently,a growing body of new evidence has been published on various aspects of CVT diagnosis and treatment,including studies on prognosis assessment scales and EVT therapy.Anticoagulation remains the primary treatment during the acute phase of CVT,as demonstrated by the thrombolysis or anticoagulation for cerebral venous thrombosis(TOACT)clinical trial.This study revealed that EVT combined with standard medical care did not improve functional outcomes for patients with severe CVT.Several risk screening scores have been developed to predict CVT prognosis,and some of these scales have been shown to perform adequately.The question of whether EVT is beneficial for patients with CVT,and to which subgroups of patients it should be offered,still remains unsettled.Large global research collaborations should be established to address current challenges and facilitate the execution of clinical trials. 展开更多

Increasing evidence demonstrated that the blood-brain barrier(BBB)was involved in developing cerebral amyloid angiopathy(CAA).The BBB participates in the neurovascular coupling and regulates the transport of substances,which is closely related to neurodegenerative diseases.In CAA,the deposition of amyloid beta(Aβ)in arteries,capillaries,and arterioles of meninges and cerebral cortex results in the destruction of the BBB,chronic inflammatory response,chronic cerebral hypoperfusion,and dysfunction of the neurovascular unit,which eventually leads to neurodegeneration.At the same time,CAA is an age-related disease.Patients with CAA often have some risk factors for cerebrovascular diseases,such as hypertension and diabetes,which can further aggravate the damage to the BBB.Thus,it is of great significance to pay attention to the BBB in the pathogenesis and future intervention targets of CAA.Therefore,this manuscript reviewed the dysfunction of the BBB in CAA. 展开更多

Intracranial artery stenosis(ICAS)in youth is an under-explored condition.ICAS is one of the leading causes of stroke in young people worldwide and confers a higher risk of stroke recurrence,leading to a poor prognosis for individuals and a great burden to society.The etiology and risk factors of ICAS in youth differ from those of older patients,thus resulting in a difference in the progression and prognosis of the disease.Even though the diagnosis of ICAS is lumen-based,it is sometimes difficult to identify in young patients based on imaging alone.Notably,novel vessel wall imaging techniques play an important role in determining the cause of stenosis and screening patients at high risk of recurrence.Moreover,pharmacologic regimens and risk factor control goals for ICAS in young adults are largely consistent with those in older patients.Thus,considering the poor prognosis,there is an urgent need for high-quality studies in the young ICAS population to analyze the high-quality observational data collected. 展开更多

Myelopathy is a common etiology of acute bilateral limb weakness. While painless acute aortic dissection(AAD)is the most common catastrophic event that can mimic myelopathic manifestations of acute bilateral limb weakness, it is often easily ignoredWe describe a case of painless AAD in a 70-year-old man with a history of hypertension manifesting as acute myelopathy(bilateral limb weakness and loss of all types of sensation)with increased levels of serum myoglobin and D-dimer.Magnetic resonance imaging of the spinal cord revealed a normal thoracic and lumbar spinal cord but a dissection of the thoracic aorta. Computed tomography angiography of the chest and abdominal aorta showed a Stanford type B dissection extending throughout the thoracic aorta and into the abdominal aorta hypomere.The patient died because of a sudden drop in blood pressure during transfer to vascular surgery.The clinical presentation of painless AAD mimics myelopathies.Aortic dissection should be considered in patients presenting with acute bilateral limb weakness.Physical examination of the skin temperature,dorsalis pedis artery,serum D-dimer,and myocardial markers can provide diagnostic clues. 展开更多

Albumin is the most abundant protein in plasma and is synthesized primarily in the liver.It has a variety of biological roles,such as increasing colloid osmotic pressure, and performing antioxidant, anti-inflam-matory,and substance transportation functions.Several studies have confirmed that albumin has neuroprotective effects and it has been used in the treatment of cerebral edema and increased intracranial pressure.In this review we focus on the neuroprotective effects of albumin in ischemic stroke,such as the reduction of cerebral edema, antioxidant effects, protection of neuronal cell membranes, and increased cerebral blood flow. In addition, we summarize preclinical and clinical studies of albumin in ischemic stroke. We believe that the neuroprotective role of albumin should be re-investigated in the era of reperfusion therapy. 展开更多

Objective:To describe the clinical fea-tures of a case of ischemic stroke caused by pseudo severe stenosis of vertebral artery(VA).Methods:The clinical history and image data of a 52-year-old man with ischemic stroke were collected.Results:Computerized tomography angiography(CTA)revealed stenosis of V1 and V4 of the left VA.DSA confirmed that the anterior blood flow recov-ered after stent implantation,and the V4 segment of the left VA was normal without stenosis.Conclusions:It is spec-ulated that the upper stenosis is due to local hemodynamic changes rather than real stenosis.This case suggests that the interpretation of stenosis on CTA should consider cere-bral vascular anatomy and hemodynamic changes. 展开更多

Selective endovascular hypothermia has been used to provide cooling-induced cerebral neuroprotection,but current catheters do not support thermally-insulated transfer of cold infusate,which results in an increased exit temperature,causes hemodilution,and limits its cooling efficiency.Herein,air-sprayed fibroin/silica-based coatings combined with chemical vapor deposited parylene-C capping film was prepared on catheter.This coating features in dual-sized-hollow-microparticle incorporated structures with low thermal conductivity.The infusate exit temperature is tunable by adjusting the coating thickness and infusion rate.No peeling or cracking was observed on the coatings under bending and rotational scenarios in the vascular models.Its efficiency was verified in a swine model,and the outlet temperature of coated catheter(75μm thickness)was 1.8-2.0◦C lower than that of the uncoated one.This pioneering work on catheter thermal insulation coatings may facilitate the clinical translation of selective endovascular hypothermia for neuroprotection in patients with acute ischemic stroke. 展开更多

Background and purpose To evaluate relationship between fluid-attenuated inversion recovery vascular hyperintensity(FVH)after intravenous thrombolysis and outcomes in different lesion patterns on diffusion-weighted imaging(DWI).Methods Patients with severe internal carotid or intracranial artery stenosis who received intravenous thrombolysis from March 2012 to April 2019 were analysed.They were divided into four groups by DWI lesion patterns:border-zone infarct(BZ group),multiple lesions infarct(ML group),large territory infarct(LT group),and single cortical or subcortical lesion infarct(SL group).Logistic regression was performed to identify risk factors for outcome(unfavourable outcome,modified Rankin Scale(mRS)≥2;poor outcome,mRS≥3).Results Finally,203 participants(63.3±10.2 years old;BZ group,n=72;ML group,n=64;LT group,n=37;SL group,n=30)from 1190 patient cohorts were analysed.After adjusting for confounding factors,FVH(+)was associated with unfavourable outcome in total group(OR 3.02;95%CI 1.49 to 6.13;p=0.002),BZ group(OR 4.22;95%CI 1.25 to 14.25;p=0.021)and ML group(OR 5.44;95%CI 1.41 to 20.92;p=0.014)patients.FVH(+)was associated with poor outcome in total group(OR 2.25;95%CI 1.01 to 4.97;p=0.046),BZ group(OR 5.52;95%CI 0.98 to 31.07;p=0.053)and ML group(OR 4.09;95%CI 1.04 to 16.16;p=0.045)patients,which was marginal significance.FVH(+)was not associated with unfavourable or poor outcome in LT and SL groups.Conclusion This study suggests that association between FVH and outcome varies with different lesion patterns on DWI.The presence of FVH after intravenous thrombolysis may help to identify patients who require close observations in the hospitalisation in patients with border-zone and multiple lesion infarcts. 展开更多

Brain diseases,mainly including acute brain injuries,neurodegenerative diseases,and mental disorders,have posed a significant threat to human health worldwide.Due to the limited regenerative capability and the existence of the blood–brain barrier,the brain was previously thought to be separated from the rest of the body.Currently,various cross-talks between the central nervous system and peripheral organs have been widely described,including the brain-gut axis,the brain-liver axis,the brain-skeletal muscle axis,and the brain-bone axis.Moreover,several lines of evidence indicate that leveraging systemic biology intervention approaches,including but not limited to lifestyle interventions,exercise,diet,blood administration,and peripheral immune responses,have demonstrated a significant influence on the progress and prognosis of brain diseases.The advancement of innovative proteomic and transcriptomic technologies has enriched our understanding of the nuanced interplay between peripheral organs and brain diseases.An array of novel or previously underappreciated blood-derived factors have been identified to play pivotal roles in mediating these communications.In this review,we provide a comprehensive summary of blood-to-brain communication following brain diseases.Special attention is given to the instrumental role of blood-derived signals,positing them as significant contributors to the complex process of brain diseases.The insights presented here aim to bridge the current knowledge gaps and inspire novel therapeutic strategies for brain diseases. 展开更多
