Relevant studies up to March 2024 were retrieved from PubMed, Scopus, Web of Science, and Embase databases.ResultsA total of 8 papers met the inclusion/exclusion criteria comprising a total of 1140 participants (average age 72.4 ± 11.9, female percentage (50%). Preintervention intravenous thrombolysis was utilized in 46.5% (range 32.9-65.4) of patients, with a median National Institute of Health Stroke Scale at presentation of 15 (range 0-38). The middle cerebral artery was the most commonly affected artery, with a prevalence of 76.4% (range 62.8-100). The pRESET stent-retriever systems demonstrated a first-passing effect rate of 53.4% [95% confidence interval [CI] 44.8; 61.7] and a final thrombolysis in cerebral infarction 2b-3 grade rate of 90.41% [95% CI 82.13; 95.08].

We aimed to assess the possibility of ischemic core overestimation on pretreatment MRI despite using more restricted reduced diffusion (apparent diffusion coefficient (ADC) ≤620 × 10-6 mm2/s) in AIS patients with successful reperfusion.Materials and MethodsIn this retrospective single institutional study, AIS patients who had pretreatment MRI underwent successful reperfusion and had follow-up MRI to determine the final infarct volume were reviewed. Pretreatment ischemic core and final infarction volumes were calculated. Ghost core was defined as overestimation of final infarct volume by baseline MRI of >10 mL. Baseline clinical, demographic, and treatment-related factors in this cohort were reviewed.ResultsA total of 6/156 (3.8%) patients had overestimated ischemic core volume on baseline MRI, with mean overestimation of 65.6 mL. Three out of six patients had pretreatment ischemic core estimation of >70 mL, while the final infarct volume was <70 mL. All six patients had last known well-to-imaging <120 min, median (IQR): 65 (53-81) minutes.ConclusionsOverestimation of ischemic core, known as ghost core, is rare using severe ADC threshold (≤620 × 10-6 mm2/s), but it does occur in nearly 1 of every 25 patients, confined to hyperacute patients imaged within 120 min of symptom onset. Awareness of this phenomenon carries implications for treatment and trial enrollment.","PeriodicalId":14380,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"1219-1224"},"PeriodicalIF":2.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11571341/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139520845","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 aims to assess the safety and effectiveness of dual antiplatelet therapy (DAPT) in the context of RIAs.MethodsWe conducted a retrospective analysis at a single center, involving patients with aneurysmal subarachnoid hemorrhage (aSAH) between May 1, 2017 and December 31, 2021. Patients were categorized into two groups: the SAC group and the non-SAC (NSC) group. Patients in the SAC group received DAPT. We compared modified Rankin Scale (mRS) score, along with hemorrhagic and ischemic complications, between the two groups to evaluate the safety and efficacy of DAPT for SAC.ResultsThe study included a total of 541 patients, of whom 38 (7.0%) experienced hemorrhagic complications and 48 (8.9%) developed ischemic complications. Additionally, 99 (18.3%) and 84 (15.5%) had poor clinical outcomes at discharge and 6 months, respectively. However, no statistically significant differences were observed between the two groups. Our analysis revealed that aneurysm location in the posterior circulation was a significant risk factor for an unfavorable prognosis when antiplatelet drugs were used following SAC (p = 0.025).ConclusionsAdministering antiplatelet drugs after SAC for RIAs has demonstrated both safety and effectiveness. However, caution should be exercised when considering this treatment strategy for RIAs located in the posterior circulation due to the potentially elevated risk.","PeriodicalId":14380,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"1187-1196"},"PeriodicalIF":2.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11571548/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139402759","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}

Patients were treated with endovascular coil embolisation and microguidewire electrocoagulation. XperCT scans were conducted to identify new intracranial haemorrhage, infarction and hydrocephalus. Follow-up examinations were conducted 1, 3, 6 and 12 months after discharge.ResultsAfter the patients received electrocoagulation for different durations, Raymond Grade 1 embolisation was achieved in all 10 patients. No complications, such as haemorrhage, infarction or hydrocephalus, were found during or after surgery. Ten patients were followed up for 6-12 months, and none had any symptoms or new neurological dysfunction 1 month after their operation. Among them, nine were followed up for 12 months, and digital subtraction angiography showed no recurrence of aneurysms or occlusion of parent arteries.ConclusionIntra-arterial microguidewire electrocoagulation can be used as a supplementary treatment for cerebral aneurysms. In cases of incomplete lesion embolisation and cases where tamponade treatment cannot continue, immediate thrombosis may occur. Thus, intra-arterial microguidewire electrocoagulation can help achieve patients' treatment goals.","PeriodicalId":14380,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"1197-1203"},"PeriodicalIF":2.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11569753/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139402757","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}
