Though it is well known that several benefit the human body while others are linked to disease, how the microbiota affects the pathology of intra-cranial aneurysms is an interesting arena that still requires exploration. Studies have suggested possible association between the excess of bacteria, such as those causing gingivitis, as well the deficit of bacteria, such as loss of gut flora due to antibiotics, to intracranial aneurysms and their subsequent behavior.

The authors present an unusual case of a giant aneurysm of the anterior inferior cerebellar artery masquerading as a cerebellopontine angle tumour with cerebellar signs. The patient was treated with a retromastoid suboccipital craniectomy and microsurgical clipping and excision, with excellent results.

We discuss the long-term clinical and angiographic outcome of coiling of these aneurysms. Materials and Methods: We assessed a prospectively maintained database of patients with large and giant intracranial aneurysms managed by the endovascular techniques from January 2010 to December 2014. In 412 patients with 468 aneurysms managed during this period, 58 patients with 60 aneurysms were identified as either large or giant. Each patient's records were reviewed with regard to size, location and morphology of the aneurysms, Hunt and Hess grade, occlusion and coiling/recoiling rates. Clinical outcome was assessed using the modified Rankin Scale (mRS) score with score of 0–2 and 3–6 taken as favourable and unfavourable outcome, respectively. Results: Overall complication rate was 13.8%, and no intraprocedural death was seen. Angiographic and clinical follow-up was available for 49 patients with 49 aneurysms at an average of 28.7 months. Recanalisation rate was 26.5% in this study and of them 38.5% required retreatment. Favourable mRS score (0–2) was seen in 82.6% of ruptured aneurysms and 92.3% in unruptured aneurysms. Conclusion: Coiling of large and giant aneurysms is a safe and viable option with a very good clinical outcome in the long run. However, long-term clinical and angiographic follow-up is necessary as angiographic results immediately after the procedure may be deceptive.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134359467","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}

Materials and Methods: We report retrospective analysis of 9 cases with unruptured cerebral arteriovenous malformation who got admitted in the Banbuntane Hotokokai Hospital, Fujita Health University, and Nagoya, Japan .from the year 2014 to 2017.surgical treatment was appropriate craniotomy and resection based on the location of the arteriovenous malformation with multimodality monitoring with Dual Image Video Angiography, Motor Evoked Potential, and FLOW 800. We studied the following factors: Sex, Age, Arteriovenous Malformation size, Location, occurrence of Intracranial Hemorrhage, Seizure type, Duration of Seizure history, Treatment modality, and Arteriovenous Malformation obliteration. We tested for statistical associations between these factors and seizure presentation and outcomes with Clinical follow-up. Outcome was compared with modified Rankin Scale Results: Out of 9 cases operated for intracranial arteriovenous malformation 5 patients were female and 4 were male. Age [ Mean 39.4 + 16.7] of the patients ranged from 20 to 66 , 5 patients were 25 - 40 and 2 were > 65 and < 25 each.6 patients were Spetzler - Martin Grade 2 ,1 patient was Spetzler - Martin Grade 4,Grade 3 and Grade 5. 3 patients were draining into superficial venous system and 2 patient were asymptomatic and incidentally diagnosed during screening procedure. There is no Mortality in this study.1 patient underwent Gamma Knife stereotactic radiosurgery. Conclusion: The increasing use of advance imaging techniques will increase the incidence of asymptomatic arteriovenous malformations. Non-ruptured arteriovenous malformation Spetzler Martin Grade 1 or Spetzler Martin Grade 2 have a good outcome for microsurgery [modified Rankin Scale and complete obliteration and there is better outcome with microsurgery.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122959887","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}

Patients typically present with slowly progressive myelopathy that is often mistaken for degenerative cervical or lumbar stenosis. Cranial presentations are even more innocuous ranging from seizures to tinnitus. The purpose of this study is to present a series of cases to aid in the assessment, diagnosis and treatment of this unusual pathology. Case Series: We present 11 cases of AVFs treated at our centre over an 4-year period. Seventy percent of patients were male. The mean age of presentation was 62.6 years. The most common lesion was a dural AVF emanating from the craniovertebral junction with single feeder. All patients underwent either microsurgical correction or endovascular embolization as the primary procedure. Eight patients showed improvement following treatment as graded by the Nurick system. Two patients failed to improve. None of the patients worsened. One patient had a cortical venous thrombosis after embolization that resolved well with anticoagulants. Conclusion: The successful treatment of AVF requires a detailed understanding of clinical presentation and imaging findings to allow for precise treatment. Owing to the rarity of the condition, clinicians must continue to share their experiences to advance our knowledge.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127077945","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}
