BACKGROUND: Stenting and flow diversion for aneurysmal sub arachnoid hemorrhage (aSAH) require the use of dual antiplatelet therapy (DAPT). OBJECTIVE: To investigate whether DAPT is associated with hemorrhagic complication following placement of external ventricular drains (EVD) in patients with aSAH. METHODS: Rates of radiographically identified hemorrhage associated with EVD placement were compared between patients who received DAPT for stenting or flow diversion, and patients who underwent microsurgical clipping or coiling and did not receive DAPT by way of a backward stepwise multivariate analysis...

Despite the adverse effects and unclear benefit of the complete 21-day course of nimodipine therapy, The Joint Commission mandates adherence to nimodipine treatment for 21 days after hemorrhage or after hospital discharge if discharged within 21 days for Comprehensive Stroke Center (CSC) certification. We hereby present a 67 year-old male patient with Hunt-Hess grade 2 and Fisher grade 3 non-aneurysmal spontaneous subarachnoid hemorrhage who was discharged with oral nimodipine as stipulated by the CSC guidelines, and subsequently developed symptomatic hypotension...

Acute SAH from a ruptured intracranial aneurysm contributes for 30% of all hemorrhagic strokes. The bleeding itself occurs in the subarachnoid space. Nevertheless, injury to the brain parenchyma occurs as a consequence of the bleeding, directly, via several well-defined mechanisms and pathways, but also indirectly, or secondarily. This secondary brain injury following SAH has a variety of causes and possible mechanisms. Amongst others, inflammatory events have been shown to occur in parallel to, to contribute to, or even to initiate programmed cell death (PCD) within the central nervous system (CNS) in human and animal studies alike...

BACKGROUND AND PURPOSE: Delayed cerebral ischemia is a severe complication of aneurysmal SAH and is associated with a high case morbidity and fatality. The total blood volume and the presence of intraventricular blood on CT after aneurysmal SAH are associated with delayed cerebral ischemia. Whether quantified location-specific (cisternal, intraventricular, parenchymal, and subdural) blood volumes are associated with delayed cerebral ischemia has been infrequently researched. This study aimed to associate quantified location-specific blood volumes with delayed cerebral ischemia...

OBJECTIVE: It remains unknown if ultra-early (within 24 hours after SAH onset) treatment could improve prognosis in poor-grade aneurysmal subarachnoid hemorrhage (aSAH). We aimed to evaluate the effect of ultra-early treatment on the functional outcome and mortality in poor-grade aSAH patients via systematic review and meta-analysis. METHODS: We performed a literature search in PubMed, MEDLINE and Web of Science databases. Primary outcomes were death and functional outcome assessed at any time period...

INTRODUCTION: There is increasing acknowledgement that surgical care is important in global health initiatives. In particular, neurosurgical care is as limited as 1-to-10 million people in parts of the world. We performed a systematic literature review to examine the worldwide incidence of central nervous system vascular lesions (CNS-VL) and a meta-analysis of aneurysmal subarachnoid hemorrhage (ASAH) in order to define the disease burden and inform neurosurgical global health efforts...

The anterior communicating artery is a common location for intracranial aneurysms. Compared to surgical clipping, endovascular coiling has been shown to improve outcomes for patients with ruptured aneurysms and we have seen a paradigm shift favoring this technique for treating aneurysms. Access to the anterior cerebral artery can be challenging, especially in patients with tortuous anatomy or subarachnoid hemorrhage or in patients presenting with vasospasm. We present a technique for cannulating the anterior cerebral artery using a balloon inflated in the proximal middle cerebral artery as a rebound surface...

We report 2 cases of parent artery occlusion (PAO) for anterior cerebral artery (ACA) fusiform aneurysm embolization after superselective provocative testing was performed to confirm distal territory viability. The first case involves a patient in the second decade of life who presented with subarachnoid hemorrhage and underwent PAO after a balloon test occlusion in the distal ACA revealed no neurophysiology changes. The second case involves another patient in the forth decade of life who presented with an enlarging pseudoaneurysm and underwent PAO after a sodium amobarbital infusion in the distal ACA revealed no clinical change...

Spinal aneurysms are rare lesions, and their natural history is not well known. In particular, aneurysms arising from the artery of Adamkiewicz (AA) are an extremely rare phenomenon, and given the lack of solid evidence its management remains unclear. We present the case of a 54-year-old woman with spinal subarachnoid hemorrhage. A spinal angiogram demonstrated a fusiform aneurysm arising from the AA. Based on the location, the absence of evident collateral circulation to the anterior spinal artery, and the available literature supporting spontaneous thrombosis, we opted for conservative management...

Visual field defect is one of the various clinical manifestations in patients with subarachnoid hemorrhage (SAH). Little is known about the pathogenic mechanism of visual field defect in SAH. In the current study, we investigated the diffusion tensor imaging (DTI) finding of the optic radiation in patients with SAH following rupture of a cerebral artery aneurysm. We recruited 21 patients with aneurismal SAH (12 males, 9 females, mean age, 52.67 years; range, 41-68 years) who showed no definite lesion along the visual pathway...

Non-traumatic subarachnoid hemorrhage (SAH) affects an estimated 30,000 people each year in the United States, with an overall mortality of ~30%. Most cases of SAH result from a ruptured intracranial aneurysm, require long hospital stays, and result in significant disability and high fatality. Early brain injury (EBI) and delayed cerebral vasospasm (CV) have been implicated as leading causes of morbidity and mortality in these patients, necessitating intense focus on developing preclinical animal models that replicate clinical SAH complete with delayed CV...

BACKGROUND: Spontaneous blood pressure increase is frequently observed after aneurysmal subarachnoid hemorrhage (aSAH). These episodes of spontaneous blood pressure alterations are usually tolerated under the assumption of an endogenous response to maintain cerebral perfusion. The relevance of blood pressure variability and its relationship to disease severity and outcome, however, remain obscure. METHODS: A total of 115 consecutive patients with aSAH were included for this retrospective analysis of a continuously collected data pool...

We present the case of an 11-yr-old male who originally presented to an outside hospital with subarachnoid hemorrhage. He was discovered at that time to have a ruptured right A1-A2 junction anterior cerebral artery aneurysm just proximal to the anterior communicating artery. He underwent endovascular coiling at the outside center. While recovering at a rehabilitation center, he had a rehemorrhage and acute neurological decline. He was transferred to our service, where he underwent surgical exploration and clip reconstruction of what appeared to be a pseudoaneurysm...

OBJECTIVE: A growing number of non-aneurysmal subarachnoid hemorrhage (NaSAH) were found in clinical practice. However, the precise mechanisms in which D-dimer level is associated with clinical condition in patients with NaSAH remain unclear. But even more, the data assessing the risk of clinical course in the patients with NaSAH are scarce. Our objective was to investigate whether D-dimer levels correlated with complication and outcome in patients with NaSAH. METHODS: Between February 2013 and May 2017, 92 patients suffering from NaSAH were treated in our hospital...

Blood-brain barrier (BBB) dysfunction has been implicated in ischemic risk following aneurysmal subarachnoid hemorrhage (aSAH), but never directly imaged. We prospectively examined whether post-bleed day 4 dynamic contrast-enhanced magnetic resonance (DCE-MR) BBB permeability imaging could predict development of delayed cerebral ischemia (DCI). Global MR-derived BBB permeability ( Ktrans ) was significantly higher in aSAH patients who subsequently developed DCI (five patients; 2.28 ± 0.09 × 10-3 min-1 ) compared to those who experienced radiographic vasospasm only (three patients; 1...
