[PMID: 35660669 DOI: 10.1016/j.wneu.2022.05.125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 05/26/2022] [Accepted: 05/27/2022] [Indexed: 11/24/2022]
Abstract
INTRODUCTION We sought to analyze the rate of utilization of methods of cerebrospinal fluid diversion over time in a nationally representative cohort of patients admitted with aneurysmal subarachnoid hemorrhage (aSAH). METHODS The Nationwide Inpatient Sample was queried for patients admitted with aSAH from 2006 to 2018. Patients who received external ventricular drainage (EVD), lumbar drainage, ventriculoperitoneal shunt (VPS), and cerebral angiography were then identified. A Cochrane-Armitage test was conducted to assess the linear trend of proportions of EVD, lumbar drains, VPS, and mean cerebral angiograms per admission. Four regression analyses were conducted to infer the association of baseline variables to EVD, lumbar drain, VPS, and mean number of cerebral angiographies. RESULTS A total of 133,567 admissions were identified from 2006-2018 involving aSAH. Of these, 41.82% received EVD, 6.22% received lumbar drainage, 10.58% received VPS, and 75.03% had cerebral angiograms. There was an average upward trend of 1.57% in annual EVD utilization, downward trend of -0.28% in utilization of lumbar drainage, no changes in VPS utilization, and an upward trend of 0.04 angiograms per year (P < 0.001). There was a higher proportion of Black patients treated with EVD and VPS in both urban teaching hospitals and large hospitals. CONCLUSIONS Our results show the temporal trends in utilization of temporary and permanent methods of cerebrospinal fluid diversion and catheter cerebral angiography among patients with aSAH in the United States. The underutilization of VPS following EVD and the differences in EVD and VPS utilization depending on race and hospital size deserve further exploration.

Abstract
BACKGROUND Lifestyle modifications and advances in surgical and endovascular techniques for treating unruptured intracranial aneurysm (UIA) have vastly evolved over the last few decades and may have reduced the incidence of aneurysmal subarachnoid hemorrhage (aSAH). However, the actual impact of these changes on the rates and outcomes of aSAH remain unexplored. Thus, we studied national aSAH admissions and outcome trends and changes of major risk factors over time. METHODS We queried the National Inpatient Sample between 2006 and 2018 to identify adult patients admitted and treated for UIA or ruptured aneurysm with aSAH. The Cochran-Armitage test was conducted to assess the linear trend of proportion of prevalence, inpatient mortality, hypertension, and current smoking status among aSAH admissions. Multivariable logistic regression was conducted to assess the odds of presenting with aSAH versus UIA, in addition to the odds of inpatient mortality among patients with aSAH. RESULTS A total of 159,913 patients presented with UIA and 133,567 presented with aSAH. Admissions for aSAH decreased by 0.97% (p < 0.001) per year. Current smoking and hypertension were associated with higher odds of being admitted for aSAH compared with the treatment for UIA (odds ratio [OR] 1.38, 95% confidence interval [CI] 1.29-1.48; OR 1.15, 95% CI 1.08-1.22, respectively). Compared with White patients, Black patients (OR 1.32, 95% CI 1.21-1.43), Hispanic patients (OR 1.38, 95% CI 1.25-1.52), and patients of other races and/or ethnicities (OR 1.73, 95% CI 1.54-1.95) had a higher chance of presenting with aSAH. Rates of inpatient mortality among aSAH admissions showed no change over time (p = 0.21). Among patients admitted with aSAH, current smoking and hypertension showed an upward trend of 0.58% (p < 0.001) and 1.60% (p < 0.001) per year, respectively. CONCLUSIONS Despite a downward trend in the annual frequency of hospitalizations for aSAH, inpatient mortality rates for patients undergoing treatment of the ruptured aneurysm have remained unchanged in the United States. Smoking and hypertension are increasingly prevalent among patients with aSAH. Thus, efforts to control these modifiable risk factors must be further strengthened.

J Clin Neurosci 2021; 94:204-208. [PMID: 34863439 DOI: 10.1016/j.jocn.2021.10.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Revised: 09/22/2021] [Accepted: 10/24/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Association between opioid abuse and intracranial aneurysms rupture has been suggested in recent studies. However, these observations are limited to single center studies and could be benefited from validation in larger cohorts. Hence, we aimed to study the association between age at aneurysmal subarachnoid hemorrhage (aSAH) and opioid use disorders (OUD) using a large, national database. METHODS This study was conducted using the 2016 and 2017 National Inpatient Sample (NIS) with ICD-10 codes. Cohorts were categorized as "Non-users", "OUD", and "Multi-drug users". Linear regression models were used to examine the association between OUD and multi-drug users with age at aneurysm rupture, and multiple logistic regression models were used for the association between in-hospital mortality and drug abuse. RESULTS A total of 17,391 patients with aSAH were captured in the 2016 and 2017 NIS database. Out of these patients, 235 (1.4%) were included in the OUD group and 59 (0.3%) in the multi-drug users' group. Adjusted linear regression showed an unstandardized coefficient (UC) = -12.3 [95%CI = -14.4/-10.1, p < 0.001] for OUD patients and an UC = -16.8 [95%CI = -21.1/-12.5, p < 0.001] for multi-drug users, compared to non-users. The risk of in-hospital mortality was significantly increased in drug user, OR = 1.47 [95%CI: 1.1-2.01, p = 0.017] for OUD patients, and OR = 2.35 [95%CI: 1.35-4.11, p = 0.003] for multi-drug users. CONCLUSIONS This is the first national study to examine the association between age at intracranial aneurysms rupture and opioid abuse. aSAH patients with history of OUD were 12 years younger compared to non-users, when OUD was combined with other drugs, the age at aneurysms rupture was 17 years younger. Further elucidation regarding the mechanisms by which opioids triggers aneurysms rupture and predispose to worsen outcomes following aSAH is required, as well as appropriate prevention, and management strategies for aSAH patients with OUD.

Abstract
OBJECTIVE In the present retrospective cohort analysis, we examined the differences in baseline characteristics and peri- and postoperative outcomes stratified by 3 groups: cannabis abuse or dependence versus none, surgical versus endovascular treatment, and unruptured and ruptured intracranial aneurysms. METHODS A study population of 26,868 patients was defined using the 2009-2016 National Inpatient Sample database. The baseline characteristics were compared between the cannabis and no-cannabis groups, and the traits that differed significantly were factored into the multivariate analysis using 1:1 propensity score matching. The matched groups were analyzed to compare the cannabis and no-cannabis cohorts for the following endpoints: mortality, length of stay, discharge disposition, total hospital charges, and several peri- and postoperative outcomes. RESULTS In the surgically and endovascularly treated groups for unruptured intracranial aneurysms, those in the cannabis group were more likely to be male and younger and to smoke tobacco than were those in the no-cannabis group. After matching, no significant endpoint differences were noted. Similarly, in the surgically and endovascularly treated ruptured aneurysm groups, those in the cannabis group were more likely to be male and younger and to smoke tobacco. After matching, the cannabis group within the endovascular treatment group had had a longer length of stay and were more likely to have developed any hydrocephalus, obstructive hydrocephalus, sepsis, and acute kidney injury. Those in the cannabis group who had undergone surgery were more likely to have developed any hydrocephalus, specifically, communicating hydrocephalus. CONCLUSIONS The cannabis group with ruptured intracranial aneurysms was more likely to experience certain adverse outcomes after surgical or endovascular treatment compared with the no-cannabis group. However, such was not the case for cannabis abusers treated for unruptured aneurysms.

Cannabis Use and Increased Nonaneurysmal Subarachnoid Hemorrhage in the Past Decade. World Neurosurg 2021; 154:e580-e589. [PMID: 34325028 DOI: 10.1016/j.wneu.2021.07.079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Revised: 07/18/2021] [Accepted: 07/19/2021] [Indexed: 11/23/2022]
Abstract
OBJECTIVE Spontaneous subarachnoid hemorrhage is often due to rupture of an intracranial aneurysm, but some patients present with no identifiable source. Increased incidence of nonaneurysmal subarachnoid hemorrhage (naSAH) has been reported over time. METHODS We performed a retrospective analysis of naSAH from 2008-2017 to determine the rate of naSAH change over time and its association with cannabis use. Univariable and multivariable regression analyses were performed to study the trend over time, radiographic patterns of hemorrhage, and clinical outcome at the time of discharge. In addition, we compared the rate of naSAH with the rate of aneurysmal SAH (aSAH) to adjust for changes in hospital volume and prevalence/reporting of cannabis use in the population over time. RESULTS A total of 86 naSAH and 328 aSAH patients were identified, with an increase in naSAH over time compared with aSAH (P = 0.0034). Increased cannabis use was associated with naSAH (odds ratio [OR] 2.1, 95% confidence interval 1.1, 4.1, P = 0.035) but not aSAH over time. Cannabis use was also associated with different subarachnoid hemorrhage patterns (P = 0.0065) in naSAH. Multivariable analysis demonstrated good neurologic outcome after naSAH to be inversely associated with cocaine use (OR 0.008 [0.002-0.4]), ventriculostomy placement (OR 0.004 [0.03-0.50]), and anticoagulant use (OR 0.016 [0.003-0.54]) but not with cannabis use. CONCLUSIONS As cannabis use becomes more prevalent with legalization, it is important to further investigate this association with spontaneous SAH.

Abstract
PURPOSE OF REVIEW In the last few years, the attitude toward marijuana in many parts of the world has shifted from illicit to legalized for medical use and to decriminalized. In parallel, there has been a gradual increase in the consumption of this product in the general population, particularly among adolescents and young adults. Marijuana is generally perceived as a harmless drug. However, data obtained in observational studies and preclinical models have established associations between cannabis use and cardiovascular events. In addition, there is emerging evidence linking marijuana use to cerebrovascular complications. Here we provide a critical review of the literature with special emphasis on the association of cannabinoids with stroke and the possible pathogenic mechanisms involved. RECENT FINDINGS Ischemic and hemorrhagic stroke have been described in association with cannabis use, particularly in young individuals. Cerebral infarction remains the most commonly reported stroke subtype seen in marijuana users. Several pathogenic mechanisms have been proposed to explain this association, including multifocal intracranial stenosis, reversible cerebral vasoconstriction syndrome, and coexisting vascular risk factors. Cannabis use is increasingly recognized in young individuals presenting with acute stroke. Our understanding of the pathogenic mechanisms associated with cannabis use and stroke is limited but rapidly evolving. Healthcare providers should educate patients about the potential cardiovascular and cerebrovascular complications related to marijuana or cannabinoids use.
