The cross-sectional area and density of the pectoralis muscle [pectoralis muscle area (PMA) and pectoralis muscle density (PMD)] at the level of the aortic arch and the erector spinae muscle at the T12 level [erector spinae muscle area (ESMA) and erector spinae muscle density (ESMD)] were measured. The association between skeletal muscle parameters and mortality outcomes was investigated using the receiver operating characteristic (ROC) curve and multivariable logistic regression analyses.Results: The 90-day mortality rate was 32% in the study population (n = 62). The ROC analysis revealed that ESMD [area under the curve (AUC): 0.765] and PMD (AUC: 0.759) performed best in the prediction of 90-day mortality.

Many patients live far from thrombectomy centers due to large geographical variations in stroke services. This study aimed to explore the consequences of long transport distance on the proportion of thrombectomy-eligible patients who underwent thrombectomy, the clinical outcomes with or without thrombectomy, the timelines for patients transported, and the diagnostic accuracy of large-vessel occlusion in primary stroke centers.Methods: We conducted a retrospective observational study in a county with only primary stroke centers, ∼ 300 km from the nearest thrombectomy center. All stroke patients admitted over a year were retrieved from the Norwegian Stroke Registry. A neuroradiologist identified all computed tomography images with large-vessel occlusions. A panel determined whether these patients had a corresponding clinical indication for thrombectomy.Results: A total of 50% of the eligible patients did not receive thrombectomy. These patients had a significantly higher risk of severe disability or death compared to the patients who underwent thrombectomy. The median time from computed tomography imaging at the primary stroke center to arrival at the thrombectomy center was over 3 hours. Additionally, 30% of the large-vessel occlusions were initially undiagnosed, and half of these patients had a corresponding clinical indication for thrombectomy.Conclusions: In a county with a long transport distance to a thrombectomy center, a high proportion of eligible patients did not undergo thrombectomy, negatively impacting clinical outcomes. The transport time was considerable. A high rate of large-vessel occlusions was initially not diagnosed.","PeriodicalId":49174,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"15910199241278036"},"PeriodicalIF":1.5,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11571533/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analyzed various social media platforms to better understand the patient's perception of arteriovenous malformation.Methods: Twitter, Instagram, and TikTok were searched to find posts about patients' experiences with arteriovenous malformations (AVM). Posts unrelated to the patient's experience were excluded. Posts were coded for the relevant themes related to their experience with the disease, as well as engagement, and gender.Results: The most common theme was raising awareness about the condition (87.0%). Recounting symptoms (50.2%), spreading positivity (17.5%), and survival (8.3%) were other common themes. Other prevalent themes were pain (5.2%) and fear of a rare disease (3.5%). Approximately half of AVM-related Instagram (47.93%) and TikTok (52.94%) posts raised awareness about the condition. Most Instagram (67.75%) and TikTok (89.71%) posts focused on recovery and rehabilitation. Most TikTok posts discussed \"survival\" or \"death\" (57.35%), while the majority focused on spreading positivity (79.41%). Most posts were made by women (69.6%). Females were more likely than males to post about the scientific explanation of AVMs (p = 0.003).Conclusion: Social media allows patients across the country and the globe to discuss their experiences with uncommon diseases and connect with others. It also allows AVM patients to share their experiences with other patients and the public.","PeriodicalId":49174,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"15910199241272621"},"PeriodicalIF":1.5,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11571157/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142141567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers have yet to determine the relationship between deep VO status in late-window patients and imaging measures of collaterals, which are key in preserving tissue.Materials and methods: We performed a multicenter retrospective cohort study on a subset of DEFUSE 3 patients recruited across 38 centers between May 2016 and May 2017 who underwent successful thrombectomy revascularization. Internal cerebral vein opacification was scored on a scale of 0-2. This metric was added to the cortical vein opacification score to derive the comprehensive VO (CVO) score from 0 to 8. Patients were stratified by favorable (ICV+) and unfavorable (ICV-) ICV scores, and similarly CVO+ and CVO-. Analyses comparing outcomes were primarily conducted by Mann-Whitney U and χ2 tests.Results: Forty-five patients from DEFUSE 3 were scored and dichotomized into CVO+, CVO-, ICV+, and ICV- categories, with comparable demographics. Hypoperfusion intensity ratio, a marker of tissue level collaterals, was significantly worse in the ICV- and CVO- groups (p = 0.005). ICV- alone was also associated with a larger perfusion lesion (138 ml vs 87 ml; p = 0.023). No significant differences were noted in functional and safety outcomes.Conclusions: Impaired deep venous drainage alone may be a marker of poor tissue level collaterals and a greater degree of affected tissue in AIS-LVO patients presenting in the late-window who subsequently undergo successful revascularization.","PeriodicalId":49174,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"15910199241276905"},"PeriodicalIF":1.5,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11569803/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142082380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The factors affecting the difficulty in navigating the BGC from the right RA to the right common carotid artery (CCA) were investigated.Materials and methods: For 40 cases of stenosis of the right carotid artery, CAS using a 7-F Optimo BGC via the right RA was performed. Pre-operative anatomical length and angle of the access route were retrospectively examined.Results: The 7-F Optimo BGC successfully reached all lesions; however, navigational difficulties were encountered in seven out of 40 cases (17.5%). One case in the difficult group experienced an ischemic complication. The height from the topmost point of the subclavian artery (SA) to the origin of the SA (SA height) was 44.4 mm versus 28.1 mm (p < 0.01), and the angle between the SA and the CCA (SA-CCA angle) was 21.6° versus 47.9° (p < 0.01) in the difficult and easy groups, respectively. For lesions with difficult navigation, the sensitivity and specificity of the SA height >34 mm were 100% and 82%, and the sensitivity and specificity of the SA-CCA angle <30° were 100% and 82%.Conclusions: For stenosis of the right carotid artery, transradial-CAS using a 7-F Optimo BGC is a safe procedure.

Atypical presentations like tinnitus and cranial nerve symptoms have also been reported. SIH has been linked to venous sinus thrombosis; however, to our knowledge, no prior cases describe a CSF venous fistula causing SIH that leads to cerebral venous thrombosis and coma. We report a patient who developed progressive venous sinus thrombosis, leading to coma, and was found to have low intracranial pressure indicative of SIH. Invasive monitoring and imaging confirmed the low intracranial pressure, prompting a dynamic myelogram that revealed a T2/3 CSF venous fistula. The patient underwent transvenous embolization of the fistula, which resulted in the resolution of symptoms and almost immediate improvement in both venous thrombosis and intracranial hypotension. CSF venous fistulae as a cause of SIH is a recently recognized entity, with ongoing research into its treatment through transvenous embolization. Most documented cases focus on patients with headaches. This case highlights a novel presentation, emphasizing the importance of thorough diagnostic workup in patients with cerebral venous thrombosis.
