Hemodynamic augmentation with vasopressors or inotropes is traditionally used in the clinical management of post-SAH DCI. Although the rationale for such treatment is to improve the regional cerebral blood flow (rCBF) to prevent secondary ischemia, brain-perfusion data underlying such systemic hemodynamic manipulation are limited. Here, we present two cases of SAH with symptomatic DCI caused by focal or multiple-vessel vasospasm to demonstrate the effects of dobutamine on serial rCBF measurements using ¹⁵O-labelled water positron-emission tomography. In the patient with localized proximal vasospasm, immediate rCBF uptake was observed in affected brain areas, yielding neurological improvement soon after dobutamine infusion and increasing cardiac output above normal levels. In the other patient, no rCBF responses were observed in multiple and diffuse vasospasm-affected regions, resulting in severe cerebral infarction and functional impairments. We speculate that dobutamine may act via the relief of microcirculatory disturbance attributable to vasospasm, as demonstrated by the increased velocities of circulating blood in cortical microvessels distal to the vasospasm early after infusion rather than in the spastic vessels themselves. This is the first report to present the effectiveness and limitations of the acute rCBF response to hyperdynamic therapy with dobutamine for DCI, depending on the extent and severity of the vasospasm.</p>","PeriodicalId":9288,"journal":{"name":"Brain Circulation","volume":"12 3","pages":"302-309"},"PeriodicalIF":5.2,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13524394/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148850170","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}

CVT can present with wide variation of clinical characteristics, with headache being the most common clinical manifestation. Diagnosis is based on radiological imaging. The mainstay of CVT management is prompt initiation of anti-coagulation.

Neuropathic pain, often unresponsive to standard treatments, is closely associated with oxidative stress as a key factor in its pathophysiology. This study utilizes the Web of Science Core Collection to analyze 699 articles related to \"antioxidants\" and \"neuropathic pain.\" CiteSpace software was employed to examine publication trends, global collaborations, co-citation networks, and research hotspots. Results indicate a consistent rise in research activity, peaking in 2022, with China, India, and Italy as leading contributors. The University of Florence and Universidade Federal de Santa Maria emerged as prominent institutions, while influential authors included Pol Olga and Trevisan Gabriela. Key studies highlighted oxidative stress and neuropathic pain mechanisms, with neuroinflammation and specific molecular pathways gaining attention as emerging research foci. The findings underscore the growing interest in antioxidant therapies as potential interventions for neuropathic pain. Despite significant advances in understanding underlying mechanisms, there is a need for further exploration of novel antioxidants and their clinical applications. Enhanced international collaboration and the use of advanced molecular techniques are essential to drive future progress in this field.</p>","PeriodicalId":9288,"journal":{"name":"Brain Circulation","volume":"11 2","pages":"113-126"},"PeriodicalIF":2.3,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12164787/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144301133","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}
