SICH refers to brain haemorrhage in the absence of trauma and is often associated with hypertension. It is a conventional belief that hypertension is the aetiology in most of the haemorrhage in the basal ganglia region, and angiography is rarely performed in such patients. This protocol carries a risk of missing potentially curable underlying vascular conditions such as arteriovenous malformations and aneurysms, especially in younger patients without a history of hypertension. Performing an angiogram for all patients however is an overkill and unnecessary waste of resources. The role of cerebral angiography to distinguish a primary SICH from secondary SICH in all patients with SICH is thus controversial. Hence, it is the choice of the type of angiogram between digital subtraction angiogram Digital Subtraction Angiography (DSA) and computerised tomography angiogram Computerised Tomography Angiography (CTA). This article attempts to review the current diagnostic angioimaging guidelines for intracerebral haemorrhage with an aim to evolve a management protocol.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127617098","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 present a 42-year-old male, smoker and hypertensive who came with acute onset vertigo and gait ataxia. Cerebellar signs were positive on the left side. Diffusion-weighted brain magnetic resonance imaging showed acute infarct in the left anterior inferior cerebellar artery (AICA) territory. Computed tomography angiography showed BA double adjacent fenestration of proximal segment of BA, without thrombus, dissection/aneurysm. To the best of our knowledge, only three cases of double adjacent BA fenestration have been described so far. The association between vertebro-BA fenestrations and posterior circulation stroke is controversial. It has been suggested that turbulent flow at the site of fenestration predisposes to thrombus formation, which may be cause of stroke. This rare anatomic variant of the posterior circulation is important to recognize and may have associated neurologic consequences (double BA fenestrations are rare yet known congenital variants associated with aneurysms and associated neurological implications) (double adjacent BA fenestration presenting with AICA infarct are still rarer with only three cases reported across the world).","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129422055","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}

Posterior circulation perforator artery aneurysms are sparsely reported in the literature. The natural history of these rare lesions remains unclear and their diagnosis and management are not well defined. Materials and Methods: All case reports and case series from the past 20 years were analysed, and the results tabulated. Based on broad trends, guidelines were proposed for management. Results: Forty-two cases from 22 case reports and case series were analysed. Most were managed endovascularly, with a complication rate approaching 43%. Observation was another popular treatment option with however a comparable morbidity of 42% only surgery proved to be better overall. Aneurysm size was inversely correlated with complication rate with smaller lesions more prone to rupture and complications. The nature of the perforating artery was also found to be a factor, where direct brain stem perforators from the upper two-third of the basilar artery were found to be difficult to treat both by surgery and endovascular methods, leading to significant failures and complications as compared to the wider circumflex perforating arteries. Conclusion: Scarce published literature that addresses the limited understanding of the natural course of this entity lead to difficulties in proposing broad-based recommendations that are fail proof. Nevertheless, we hope this analysis of 20 years of data helps in shedding light on this difficult disease and its possible treatment options along with risks and outcomes.","PeriodicalId":218723,"journal":{"name":"Journal of Cerebrovascular Sciences","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122216248","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}

They can occur following blunt or penetrating head trauma and are more common in the paediatric population. Traumatic aneurysms are typically associated with an acute episode of delayed intracranial haemorrhage with an average time from initial trauma to aneurysm haemorrhage of approximately 21 days.
