The location of the dissecting aneurysms was the vertebral artery in three patients and basilar artery in two. In all patients, Enterprise VRD was successfully deployed in the dissecting segment, and the coils were inserted in the aneurysmal dilatation by semi-jailing technique. Ischemic complication occurred in two patients and rebleeding occurred in one patient four months after the treatment. Favorable outcomes were obtained in four of the five patients. Enterprise VRD provides easy access to the lesion, is less stressful to the parent artery in the deployment, is conformable to the tortuous parent artery, and is suitable for the semi-jailing technique. Stent-assisted coil embolization using Enterprise VRD can be a feasible and effective treatment in selected patients with ruptured vertebrobasilar dissecting aneurysms not suitable for parent artery occlusion.","PeriodicalId":131030,"journal":{"name":"Surgery for Cerebral Stroke","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115962496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Case presentation: A 70-year-old woman presented with left conjunctival injection, eyelid edema and abducens palsy. Angiograms revealed DAVF at the ACC. The arterial supply was the left ascending pharyngeal artery (APA) with retrograde venous drainage into the superior ophthalmic vein (SOV) through the ACC and inferior petrosal sinus (IPS). The patient was successfully treated with transvenous coil embolization. Conclusion: DAVF of the ACC is relatively rare. Although most cases of ACC DAVF start with tinnitus, this case showed ocular manifestations very similar to DAVF of the cavernous sinus fistula as the initial symptoms. Endovascular treatment is usually feasible and effective, but an understanding of the venous anatomy and pathophysiology of the disease are of utmost importance when planning the approach.","PeriodicalId":131030,"journal":{"name":"Surgery for Cerebral Stroke","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133517256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, urgent CEA for acute stroke is not common because of medical resources. We carried out urgent CEA for patients with medical treatment resistance. The aim of this study was to determine the safety and benefit of urgent CEA with medical treatment resistance. Methods: Seventy-six consecutive patients underwent CEA at the Kyushu Medical Center between April 2007 and April 2011. Medical treatment resistance was diagnosed by repeat stroke or plaque diagnosis. Survival follow-up, NIHSS and the incidence of stroke were investigated all patients. Results: A total 15 patients in medical treatment resistance were enrolled. ICA stenosis was average NACET 56% (18 – 95%). The median days from event to CEA were 12 days (2 – 28 days). Plaque diagnosis suggested unstable plaque in all cases. There was no stroke recurrence in 30 days and no increase of NIHSS score, respectively. Conclusions: For the patients in medical treatment resistance, urgent CEA is associated with an acceptable outcome and satisfactory benefits. Plaque diagnosis is necessary to determine medical treatment resistance.","PeriodicalId":131030,"journal":{"name":"Surgery for Cerebral Stroke","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127462334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We retrospectively reviewed 123 patients hospitalized between Apr. 2008 and Dec. 2010. Among them, 27 patients (22.0%) showed hematoma enlargement within 24 hours after hospitalization. We compared the clinical characteristics of patients with and without hematoma enlargement. Results: There were significant differences in the initial size of the hematoma, spot sign, and pretreatment with anticoagulants, but not in hypertension, diabetes mellitus, or pretreatment with antiplatelets. Conclusions: We confirmed that the initial size, spot sign, and anticoagulants were risk factors for hematoma enlargement. Careful follow-up is needed for ICH patients with these factors.","PeriodicalId":131030,"journal":{"name":"Surgery for Cerebral Stroke","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114724883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Between 2006 and 2011, we experienced 379 aneurysmal clipping surgeries (209 ruptured, 170 unruptured) at Fuji Brain Institute and Hospital. With daily thorough in-vitro microsurgical training, we performed standard-sized craniotomies with open fissures such as the sylvian fissure or interhemispheric fissure, to obtain a safe wide surgical field for clipping to compensate for the lack of experience in young neurosurgeons. We made every effort to be meticulous rather than fast to maintain treatment safety. To enhance the understanding for the surgical setting, method and strategy, we standardized procedures in detail to maximize the practice effect for residents with a limited amount of surgical experience. We discuss our institutional experiences in developing the surgical skills of young neurosurgeons, with the aim of having residents perform real neurosurgical micro-operations under the supervision of a staff doctor without compromising safety.","PeriodicalId":131030,"journal":{"name":"Surgery for Cerebral Stroke","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127609194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
