There are various procedural aspects related to liquid embolic (LE) injection that could influence radiographic resolution rates but require further study.MethodsA retrospective review of consecutive MMAe procedures using LEs performed at a single institution was performed. Technical factors investigated included type of LE, microcatheter position during embolization, number of branches embolized, and depth of penetration. Outcomes included rescue treatment within 90 days, complete hematoma and midline shift (MLS) resolution, and modified Rankin Scale (mRS) 0-2 at 90 days.ResultsA total of 122 MMA embolizations performed on 95 patients (mean age 70.3 years, 66% male) were included. Hematoma recurrence requiring rescue treatment occurred for 12 hematomas (9.8%) among 10 patients. None of the technical factors were associated with rescue treatment, early MLS resolution, final hematoma resolution, final MLS resolution, or 90-day mRS 0-2. Contralateral penetration of embolisate was associated with increased odds of complete hematoma resolution (OR 8.4, 95% CI 1.79-50.38; <i>p</i> = 0.011) at early follow-up (median 2 months). The mean (± SD) hematoma reduction at early follow-up for contralateral penetration was 76.8% (37.2) compared to 56.5% (36) for only ipsilateral penetration (<i>p</i> = 0.047).ConclusionContralateral penetration of LE may be associated with faster complete hematoma resolution but not the final radiographic result.

In this study, we quantitatively measured vascular diameter changes during the vasospasm period at various vascular sites to investigate the association between the radiological and clinical effects of clazosentan.Materials and MethodsWe retrospectively analyzed 22 patients with aSAH classified as Fisher group 3, treated at our hospital. Clazosentan (10 mg/h) was administered to 12 patients, while 10 patients received conventional vasospasm management. Arterial diameters at 12 locations were measured at the onset and during the vasospasm period. Quantitative changes in vascular diameter were compared between the clazosentan and nonclazosentan groups.ResultsDuring the vasospasm period, mean arterial diameters increased in all regions, including the posterior circulation, except internal carotid artery (ICA) top in the clazosentan group, while they decreased across all regions in the nonclazosentan group (overall average: + 22.3% vs. -16.9%; <i>p</i> = 0.005). Notably, in the clazosentan group, significant vasodilation was observed in distal arteries (M2: + 46.1%, <i>p</i> = 0.003; M3: + 58.2%, <i>p</i> = 0.001) compared to proximal arteries (ICAtop: -10.7%, <i>p</i> = 0.33; M1p: + 0.38%, <i>p</i> = 0.16; M1d: + 3.6%, <i>p</i> = 0.07). Symptomatic vasospasm occurred exclusively in the nonclazosentan group; however, no significant difference was observed in modified Rankin Scale scores 3 months post-onset (<i>p</i> = 0.38).ConclusionsClazosentan demonstrated a significant vasodilatory effect compared to conventional treatments, particularly in distal arteries. However, its limited effect on proximal arteries suggests a need for supplementary treatments targeting these regions to improve clinical outcomes. Differences in vasodilatory effect at various sites may be associated with the controversy regarding clazosentan's clinical effects.</p>","PeriodicalId":14380,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"15910199251362730"},"PeriodicalIF":2.1,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12328354/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144789116","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}
