RAPID (iSchemaView, Menlo Park, CA, USA) is the most common software for analyzing brain perfusion images worldwide, but various other software are also available. The optimal threshold value for each software is different, and each has its characteristics. This study investigated the relationship between the quantitative evaluation of ischemic core volume (ICV) and the Alberta Stroke Program Early CT Score (ASPECTS) using CT Perfusion 4D (GE Healthcare Inc., Milwaukee, WI, USA), a software used in our hospital.Methods: Among patients who underwent MT between April 2015 and February 2023, those with modified Rankin Scale: 0-2, obstruction by embolic mechanism, and thrombolysis in cerebral infarction: 2b or higher were selected retrospectively. Patients with middle cerebral artery M1 segment (M1) and internal carotid artery (ICA) occlusions (90 and 46 patients) were included. We quantitatively analyzed ICV at relative cerebral blood flow (rCBF) <20% and cerebral blood volume (CBV) <1 mL/100 g and evaluated the relationship with ASPECTS scores in 3 groups: M1 + ICA, M1, and ICA occlusion groups.Results: The median ICV was rCBF <20%: 44.7 cm3 and CBV <1 mL/100 g: 34.6 cm3, and there was no statistically significant difference between the 2 groups (p = 0.23). There was a negative correlation between ICV and ASPECTS scores in each occlusion group in all groups.Conclusion: The quantitative evaluation of ICV at rCBF <20% and CBV <1 mL/100 g was negatively correlated with the ASPECTS score in GE's CT Perfusion imaging analysis software.","PeriodicalId":73856,"journal":{"name":"Journal of neuroendovascular therapy","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11873743/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143544260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike robotic surgery in these fields, endovascular treatment involves simple movements such as pushing and pulling or twisting catheters and wires, allowing for the creation of relatively straightforward robotic systems that can replicate these endovascular procedures. Recently, there have been clinical applications of this technology in coronary arteries. However, when applying it to cerebral vessels, which have significant curvature and fragility, it is essential to develop a system that can adequately assess and reflect the physical stress on the vessel wall. Furthermore, remote surgery (telesurgery) performed by specialists is one of the most sought-after applications of robotics, but issues remain due to poor communication environments, leading to delays in operation and control difficulties. Additionally, there are ethical concerns regarding the responsibility for adverse events related to robotic surgery, highlighting the urgent need for the establishment of guidelines.","PeriodicalId":73856,"journal":{"name":"Journal of neuroendovascular therapy","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11911030/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143652374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

JSNET offers 2 main certifications: specialist and instructor. Specialists perform basic procedures, while instructors lead in practice, education, and research. In 2020, the mechanical thrombectomy practitioner qualification was added to promote mechanical thrombectomy. Applicants must have a JSNET membership, relevant certifications, training, and documented experience. The certification process includes rigorous written and practical examinations that now employ non-fluoroscopic models. Certification renewal every 5 years requires conference participation and a continuing education program. Public awareness and integration into stroke center designations have grown.

We report 2 cases where sublingual administration of nitroglycerin (NTG), a vasodilator, before CTA enabled good visualization of the AKA in patients with SDAVF.Case presentation: (Case 1) A patient in his 60s presented with progressive gait disturbance, and an MRI revealed a spinal vascular lesion. CTA with sublingual NTG administration revealed an SDAVF supplied by the right seventh intercostal artery and an AKA branching from the left ninth intercostal artery. A chronic descending aortic dissection was identified on CTA, but spinal angiography was not performed. The patient was successfully managed with direct surgical disconnection of the SDAVF, and his symptoms improved. (Case 2) A patient in his 60s presented with progressive bilateral lower-limb numbness, and a thoracic SDAVF was diagnosed using MRI. CTA without NTG administration failed to identify the AKA, but after the administration of NTG, a clear depiction of the AKA branching from the left 10th intercostal artery was obtained.

This condition accounts for approximately 4% of traumatic cerebrovascular injuries. Various symptoms can be observed in TCCF, and aggressive treatment is frequently required. Herein, we reviewed the treatment of TCCF in our hospital.Methods: We retrospectively reviewed patients with TCCF between December 2021 and May 2023. The physical findings, clinical images, and surgical details of patients were investigated.Results: Three men and 1 woman were included. Only 1 case was diagnosed with CCF using initial 3D-CTA; the other 3 were diagnosed after admission using DSA. All patients received endovascular treatment; 2 were initially treated with transarterial embolization, and the other 2 were treated with transvenous embolization, although 1 case of transarterial embolization required additional treatment with transvenous embolization. Complete occlusion was achieved in all cases. Two of the cases were accompanied by skull base fractures, both of which were middle fossa fractures.Conclusion: TCCF is caused by direct injury to the internal carotid artery and can be accompanied by skull fractures or vessel wall damage as a result of shear force. We should suspect TCCF, especially when a skull base fracture is detected, even if the initial 3D-CTA shows no evidence of TCCF. Treatment for TCCF is mainly endovascular; however, the specific treatment approach should be determined for each case based on various factors, including vessel anatomy.","PeriodicalId":73856,"journal":{"name":"Journal of neuroendovascular therapy","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12035768/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144065230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After 6 months, the patient underwent CT screening, which revealed destruction of the petrous bone and a pseudoaneurysm at the petrous segment of the left internal carotid artery. Catheter angiography, including a balloon occlusion test, revealed a 47-mm wide-necked pseudoaneurysm at the distal cervical segment of the left internal carotid artery with poor collateral blood supply to the left internal carotid artery. We performed reconstructive endovascular treatment using a FRED.
