Subarachnoid hemorrhage as bleeding pattern occurs rarely in ruptured arteriovenous malformations (AVM). The aim of the present study is to evaluate different bleeding patterns in hemorrhages due to an AVM and their impact on outcome in terms of risk and treatment stratification. We evaluated 158 patients with ruptured AVMs who were admitted to our neurosurgical department from 2002 to 2017. We compared different bleeding patterns, such as intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), or both (ICH + SAH) and evaluated predictive variables for outcome in the last follow-up...

BACKGROUND: Several possible mechanisms exist for the spread of a primary tumor to the leptomeninges in leptomeningeal carcinomatosis. This report describes a case caused by direct bleeding in the subarachnoid space from a neoplastic cerebral aneurysm rupture. CASE DESCRIPTION: A 48-year-old Japanese woman, who was diagnosed with breast carcinoma (pT3 pN2 M0) at the age of 45 years and underwent mastectomy and chemotherapy, was admitted in a coma following a sudden-onset severe headache...

Spinal arachnoid cysts (SAC) are rare in isolation and the exact aetiology is still debated. Primary (congenital) cysts are caused by structural abnormalities in the arachnoid layer and largely affect the thoracic region. Secondary cysts are induced by a multitude of factors, infection, trauma or iatrogenic response, and can affect any level of the spinal cord. While subarachnoid haemorrhage (SAH) is a relatively common condition with significant repercussions, it is extremely uncommonly associated with SAC...

Aneurysmal subarachnoid hemorrhage remains serious hemorrhagic stroke with high morbidities and mortalities. Aneurysm rupture causes arterial bleeding-induced mechanical brain tissue injuries and elevated intracranial pressure, followed by global cerebral ischemia. Post-subarachnoid hemorrhage ischemia, tissue injuries as well as extravasated blood components and the breakdown products activate microglia, astrocytes and Toll-like receptor 4, and disrupt blood-brain barrier associated with the induction of many inflammatory and other cascades...

BACKGROUND: Volumetric assessment of aneurysmal bleeding has been evaluated in few studies and emerged as a promising outcome predictor. There is a lack of studies evaluating its impact in the poor-grade population. METHODS: Retrospective review of 63 consecutive poor-grade aneurysmal subarachnoid hemorrhage (aSAH) patients, defined as grade IV and V according to the World Federation of Neurological Surgeons (WFNS) classifications. Global intracranial bleeding volume was calculated with its subarachnoid, intracerebral (ICH), and intraventricular (IVH) portions by means of analytical software...

BACKGROUND: Little data exists regarding reversal and resumption of antithrombotics following left ventricular assist device (LVAD)-associated intracranial hemorrhage (ICH). METHODS: Prospectively collected data of LVAD patients with ICH was reviewed. Coagulopathy reversal agents, antithrombotic regimens and thrombotic (venous thromboembolism, ischemic stroke, myocardial infarction) and hemorrhagic (recurrent ICH, gastrointestinal bleed, anemia requiring transfusion) complications were recorded...

The TNF-α antagonists are the drugs used for the treatment of ulcerative colitis (UC). Nontraumatic convexity subarachnoid hemorrhage is an infrequent nonaneurysmal subtype of subarachnoid bleeding caused mainly by reversible cerebral vasoconstriction syndrome (RCVS), cerebral amyloid angiopathy, and posterior reversible encephalopathy syndrome (PRES). We present a 26-year-old female patient with a diagnosis of UC taking Adalimumab. She received her last doses the same day she was admitted to our hospital for an acute severe UC exacerbation...

The number of invasive procedures in medicine is increasing, as is the employment of new technological achievements. In the era of information-communication technology, one such achievement is also the telemedicine network. In Slovenia, it is known as the Telekap (TeleStroke) network, which was primarily designed for fast and efficient management of stroke patients. In the neurosurgical community, the system is frequently used also for conveying vital information regarding subarachnoid haemorrhage and trauma...

Hypertensive crisis is a serious medical condition defined as severely elevated blood pressure; typically the systolic blood pressure is above 180 mmHg, and/or the diastolic blood pressure is above 120 mmHg. Hypertensive crises are divided into two categories: hypertensive urgency and hypertensive emergency. Hypertensive urgency is asymptomatic while hypertensive emergency presents with end-organ damage requiring more aggressive blood-pressure lowering. The common presentations for neurological end-organ dysfunction in conjunction with hypertensive emergency include ischemic strokes, intracranial hemorrhage, subarachnoid hemorrhage, head trauma, and hypertensive encephalopathy...

OBJECTIVE: The risk of hemorrhagic events in small ruptured aneurysms remains unclear. Due to less arterial wall, small ruptured aneurysms may be correlated with massive bleeding and rebleeding. Therefore, it may contribute to treatment to evaluate the amount of bleeding and the risk of rebleeding in small ruptured aneurysms. METHODS: A retrospective cohort study of all consecutive patients with intracranial aneurysms admitted to our hospital from February 2013 to December 2017 was carried out...

BACKGROUND: Delayed cerebral ischemia (DCI) is an independent predictor of an unfavorable outcome after aneurysmal subarachnoid hemorrhage (aSAH). Many centers, but not all, use transcranial Doppler (TCD) to screen for vasospasm to help predict DCI. We used the United Kingdom and Ireland Subarachnoid Haemorrhage (UKISAH) Registry to see if outcomes were better in centers that used TCD to identify vasospasm compared to those that did not. METHODS: TCD screening practices were ascertained by national survey in 13 participating centers of the UKISAH...

Superficial siderosis (SS) associated with craniopharyngioma is an extremely rare occurrence. To our knowledge, only three cases have been reported in literature. Two of the cases occurred following resection of the tumor. Similar to the present case, one of the cases was discovered prior to surgical intervention, 'pure tumor-related' SS. The clinical presentation, diagnosis, management and outcome are discussed in this article. A 50-year-old man presented with an 11-month history of left-sided tinnitus, hearing impairment and a 2-month history of visual disturbance...
