In this report, we present our series of eight cases of VSS for symptomatic tumor-induced venous sinus stenosis and review the existing literature.CasesEight patients with mostly intracranial tumors were found to have symptomatic venous sinus stenosis with the most common presenting symptom being elevated intracranial pressure. Six of the eight (75%) patients presented with papilledema on neuro-ophthalmological exam. The most affected locations were the transverse and sigmoid sinuses in four patients, followed by the superior sagittal sinus in three patients. All eight patients underwent VSS with no adverse events. In total, 6 out of 8 (75%) of patients had complete resolution of their symptoms, while the remaining patients experienced at least partial improvement.ConclusionTumors that cause symptomatic venous sinus stenosis may be successfully managed with VSS to improve venous drainage.

This study evaluates the safety and efficacy of CAS performed within a short time frame from symptom onset.MethodsWe conducted a single-center, retrospective study of consecutive patients who underwent CAS for symptomatic carotid stenosis within eight days of symptom onset from July 2019 to January 2022. Data on demographics, medical history, procedural details, and follow-up outcomes were analyzed. The primary outcome measure was the recurrence of the stroke within the first month post-procedure. Secondary outcomes included mortality, the rate of intra-procedural complications, and hyperperfusion syndrome.ResultsWe included 93 patients with a mean age of 71.7 ± 11.7 years. The median time from symptom onset to CAS was 96 h. The rate of stroke recurrence was 5.4% in the first month, with a significant association between the number of stents used and increased recurrence risk. Mortality within the first month was 3.2%, with an overall mortality rate of 11.8% after a median follow-up of 19 months. Intra-procedural complications were present in five (5.4%) cases and were related to the number of stents used (<i>p</i> = 0.002) and post-procedural angioplasty (<i>p</i> = 0.045). Hyperperfusion syndrome occurred in 3.2% of cases.ConclusionEarly CAS within the high-risk window post-symptom onset is a viable secondary stroke prevention strategy in patients with symptomatic carotid artery stenosis.

Subanalyses were conducted for Sim&Size and PreSize software.ResultsTen studies comprising 658 IAs were included. Pipeline Embolization Device was most commonly used. Findings demonstrated (1) high accuracy of VSS when comparing simulated and postoperative lengths (MD -1.7 mm; 95% CI -4.37 to 0.98 mm); (2) physician-chosen lengths overestimated compared to VSS (MD -2.11 mm; -3.43 to -0.79 mm); (3) no significant difference in physician- versus VSS-chosen diameters (MD -0.04 mm; -0.13 to 0.06 mm); and (4) high VSS-guided deployment success (96%; 93-99%) with low complications (4%). Subanalyses showed 95% and 92% deployment success rates for Sim&Size and PreSize, respectively.ConclusionVSS effectively estimates device length and achieves high deployment success, with low complication rates, supporting its utility in EVT planning.</p>","PeriodicalId":49174,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"1852-1860"},"PeriodicalIF":1.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11873847/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538021","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}
