Aneurysmal subarachnoid hemorrhage (aSAH) continues to be associated with significant morbidity and mortality despite advances in care and aneurysm treatment strategies. Cerebral vasospasm continues to be a major source of clinical worsening in patients. We intended to review the clinical and experimental aspects of aSAH and identify strategies that are being evaluated for the treatment of vasospasm. A literature review on aSAH and cerebral vasospasm was performed. Available treatments for aSAH continue to expand as research continues to identify new therapeutic targets. Oral nimodipine is the primary medication used in practice given its neuroprotective properties. Transluminal balloon angioplasty is widely utilized in patients with symptomatic vasospasm and ischemia. Prophylactic “triple‐H” therapy, clazosentan, and intraarterial papaverine have fallen out of practice. Trials have not shown strong evidence supporting magnesium or statins. Other calcium channel blockers, milrinone, tirilazad, fasudil, cilostazol, albumin, eicosapentaenoic acid, erythropoietin, corticosteroids, minocycline, deferoxamine, intrathecal thrombolytics, need to be further investigated. Many of the current experimental drugs may have significant roles in the treatment algorithm, and further clinical trials are needed. There is growing evidence supporting that early brain injury in aSAH may lead to significant morbidity and mortality, and this needs to be explored further. 相似文献

Although aneurysmal subarachnoid hemorrhage (aSAH) accounts for only 3–5% of all strokes, a high degree of morbidity has been reported in this relatively young subset of patients. Neuropsychiatric disturbance has often been neglected in these reports. We aimed to investigate the pattern and pathological factors of chronic neuropsychiatric disturbance in aSAH patients. This cross-sectional observational four-center study was carried out in Hong Kong. Neuropsychiatric outcome (Neuropsychiatric Inventory Chinese Version [CNPI]) assessments were conducted cross-sectionally 1–4 years after ictus. Pathological factors considered were early brain injury as assessed by admission World Federation of Neurosurgical Societies grade, aneurysm treatment (clipping versus coiling), delayed cerebral infarction, and chronic hydrocephalus. One hundred and three aSAH patients’ spouses or caregivers completed the CNPI. Forty-two (41%) patients were reported to have one or more domain(s) of neuropsychiatric disturbance. Common neuropsychiatric disturbance domains included agitation/aggression, depression, apathy/indifference, irritability/lability, and appetite/eating disturbance. Chronic neuropsychiatric disturbance was associated with presence of chronic hydrocephalus. A subscore consisting of the five commonly affected domains seems to be a suitable tool for aSAH patients and should be further validated and replicated in future studies. 相似文献

Radiological evaluation of subarachnoid hemorrhage (SAH) is often subject to interobserver variability. The aim of this study was to retrospectively detect computed tomography (CT) texture parameters in the early postictal state to predict cerebral vasospasm, delayed cerebral ischemia (DCI), and functional outcome in aneurysmal SAH using quantitative CT texture analysis (CTTA) via a commercially available software program and routine CT images. 40 patients with aneurysmal SAH surgically treated at the Keio University Hospital during a four-year period were analyzed. CT texture analyses were performed using a commercially available software program (Synapse Vincent). The following texture parameters of blood clots in the subarachnoid space and cerebral edema were assessed: mean CT value, entropy, skewness, and kurtosis. The mean CT value of blood clots in the subarachnoid space was significantly associated with cerebral vasospasm, DCI, and functional outcome. The mean CT value ≥ 49.64 Hounsfield units (HU) predicted cerebral vasospasm with a sensitivity and specificity of 85.7% and 61.5%, respectively (area under the curve [AUC] = 0.758). The mean CT value ≥ 49.95 HU predicted DCI with a sensitivity and specificity of 100% and 60.6%, respectively (AUC = 0.810). The mean CT value ≥ 53.00 HU predicted poor functional outcome with a sensitivity and specificity of 56.3% and 91.7%, respectively (AUC = 0.747). CTTA using a commercially available software program demonstrated that the mean CT value of clots in the subarachnoid space in the early postictal state could predict vasospasm, DCI, and clinical outcome with a high sensitivity and specificity. 相似文献

ObjectiveThe mortality of re-bleeding following aneurysmal subarachnoid hemorrhage is high, and surviving patients often have poor clinical condition and worse outcome than patients with a single bleed. In this study, we performed an updated systematic review and meta-analysis to determine the most common risk factors for re-bleeding in this patient population, with the goal of providing neurologists, neurosurgeons, neuro-interventionalists with a simple and fast method to evaluate the re-bleeding risk for aneurysmal subarachnoid hemorrhage.MethodWe conducted a thorough meta-analysis of the risk factors associated with re-bleeding or re-rupture of intracranial aneurysms in cases published between 2000 and 2013. Pooled mean difference was calculated for the continuous variables (age), and pooled odds ratio (OR) was calculated for categorical factors. If heterogeneity was significant (p < 0.05), a random effect model was applied; otherwise, a fixed model was used. Testing for pooled effects and statistical significance for each potential risk factor were analyzed using Review Manager software.ResultsOur literature search identified 174 articles. Of these, only seven retrospective studies met the inclusion criteria. These seven studies consisted of 2470 patients, 283 of which had aneurysmal re-bleeding, resulting in a weighted average rate of re-bleeding of 11.3% with 95% confidence interval [CI]: 10.1–12.6. In this population, sex (OR 1.46; 95% CI: 1.11–1.92), high systolic blood pressure [SBP] (OR 2.52; 95% CI: 1.40–4.53), aneurysm size (OR 3.00; 95% CI: 2.06–4.37), clinical condition (Hunt & Hess) (OR 4.94; 95% CI: 2.29,10.68), and Fisher grade (OR 2.29; 95% CI: 1.45, 3.61) were statistically significant risk factors for re-bleeding.ConclusionSex, high SBP, high Fisher grade, aneurysm size larger than 10 mm, and poor clinical condition were independent risk factors for aneurysmal re-bleeding. The importance of early aneurysm intervention and careful consideration of patient risk factors should be emphasized to eliminate the risk of re-bleeding and poor outcome. 相似文献

This study investigated the outcome of clipping surgery for ruptured aneurysms in patients older than 80 years of age. From 1988 to 2011 data were retrospectively reviewed, and 196 patients treated with clipping obliteration for aneurysmal subarachnoid hemorrhage were identified. Patients were divided into two age groups of 80–84 and ⩾85 years old. The Glasgow Outcome Scale score was assessed at discharge and classified as favorable (good recovery or moderate recovery) or unfavorable (severe disability, vegetative state, or dead). Radiological and clinical characteristics were compared between the two groups. A favorable outcome was achieved in 106 (54.1%) of the 196 patients. Preoperative grade and Fisher grade were significantly associated with unfavorable outcome, but age was not. Based on logistic regression analysis, poor preoperative grade and ruptured anterior cerebral artery aneurysm were the predictors of unfavorable outcome, but advanced age (⩾85 years old) was not. Advanced age itself did not affect the outcome of the elderly patients who underwent clipping surgery for aneurysmal subarachnoid hemorrhage. 相似文献
