Background: Angiography negative perimesencephalic subarachnoid hemorrhage (SAH) is considered a relatively benign entity compared to aneurysmal SAH. However, some patients with angiography negative perimesencephalic subarachnoid hemorrhage with extension of hemorrhage beyond the perimesencephalic area are at increased risk for vasospasm. Here we present a series of 21 patients with angiography negative perimesencephalic pattern of SAH both with and without ventricular extension and describe their incidence of vasospasm and clinical outcomes. Methods: Retrospective chart review was performed among patients who underwent invasive angiography from 8/2007-6/2010. Inclusion criteria were presenting clinical symptoms typical of SAH, computed tomography (CT) evidence of perimesencephalic SAH with or without ventricular extension, no recent trauma or stroke, and cerebral angiography negative for aneurysm or arteriovenous malformation. 21 patients, 8 men and 13 women, with a mean age of 55.1 years met these criteria. The presenting CTs were examined and a modified Fisher Grade assigned. The patients’ clinical course was reviewed for incidence and treatment of vasospasm. The patients’ discharge summaries were evaluated and each patient given a modified Rankin Scale score. Results: The modified Fisher Scale score derived from the presenting CT was 1 for 29% (n=6), 2 for 5% (n=1), 3 for 19% (n=4), and 4 for 47% (n=10) of the patients. Amongst the 52% (n=11) of patients with intraventricular hemorrhage as defined by a modified Fisher Scale score of 2 or 4, 24% (n=5) developed angiographical evidence of vasospasm. 10% (n=2) of the patients required intra-arterial verapamil. 90% (n=9) of patients without intraventricular extension had good outcomes at discharge as defined by modified Rankin Scale score less than or equal to 2, while only 36% (n=4) of patients with angiography negative SAH with intraventricular extension had good outcomes. Conclusions: Although angiography negative perimesencephalic SAH is considered to have less associated morbidity and mortality than aneurysmal perimesencephalic SAH, patients with extension of hemorrhage into the ventricles are at increased risk for vasospasm and poor functional outcomes.

Abstract BACKGROUND: The value of neuron-specific enolase (NSE) in predicting clinical outcomes has been investigated in a variety of neurological disorders. OBJECTIVE: To investigate the associations of serum NSE with severity of bleeding and functional outcomes in patients with subarachnoid hemorrhage (SAH). METHODS: We retrospectively reviewed the records of patients with SAH from June 2008 to June 2012. The severity of SAH bleeding at admission was measured radiographically with the Fisher scale and clinically with the Glasgow Coma Scale, Hunt and Hess grade, and World Federation of Neurologic Surgeons scale. Outcomes were assessed with the modified Rankin Scale at discharge. RESULTS: We identified 309 patients with nontraumatic SAH, and 71 had NSE testing. Median age was 54 years (range, 23-87 years), and 44% were male. In multivariable analysis, increased NSE was associated with a poorer Hunt and Hess grade (P = .003), World Federation of Neurologic Surgeons scale score (P < .001), and Glasgow Coma Scale score (P = .003) and worse outcomes (modified Rankin Scale at discharge; P = .001). There was no significant association between NSE level and Fisher grade (P = .81) in multivariable analysis. CONCLUSION: We found a significant association between higher NSE levels and poorer clinical presentations and worse outcomes. Although it is still early for any relevant clinical conclusions, our results suggest that NSE holds promise as a tool for screening patients at increased risk of poor outcomes after SAH.

Haptoglobin Genotype

Object Haptoglobin allele heterogeneity has been implicated in differential reactive oxidant inhibition and inflammation. Haptoglobin α2-α2 has a lower affinity for binding hemoglobin, and when bound to hemoglobin, is cleared less easily by the body. The authors hypothesized that haptoglobin α2-α2 genotype should be less protective for downstream injury after aneurysmal subarachnoid hemorrhage (aSAH) and should portend a worse outcome. Methods Patients with Fisher Grade 2 or higher aSAH were enrolled in the study. Genotyping for haptoglobin genotype was performed from blood and/or CSF. Demographic information, medical condition variables, and hospital course were abstracted from the medical record upon enrollment into the study. Outcome data (modified Rankin Scale score, Glasgow Outcome Scale score, and mortality) were collected at 3 months posthemorrhage. Results The authors enrolled 193 patients who ranged in age from 18 to 75 years. Only Caucasians were used in this analysis to minimize bias from variable haptoglobin allele frequencies in populations of different ancestral backgrounds. The sample had more women than men (overall mean age 54.45 years). Haptoglobin α2 homozygotes were older than the other individuals in the study sample (57.27 vs 53.2 years, respectively; p = 0.02) and were more likely to have Fisher Grade 3 SAH (p = 0.02). Haptoglobin α2-α2 genotype, along with Fisher grade and Hunt and Hess grade, was associated with a worse 3-month outcome compared to those with the haptoglobin α1-α1 genotype according to modified Rankin Scale score after controlling for covariates (OR 4.138, p = 0.0463). Conclusions Patients with aSAH who carry the haptoglobin α2-α2 genotype had a worse outcome. Interestingly, the presence of a single α-2 allele was associated with worse outcome, suggesting that the haptoglobin α-2 protein may play a role in the pathology of brain injury following aSAH, although the mechanism for this finding requires further research. The haptoglobin genotype may provide additional information on individual risk of secondary injury and recovery to guide care focused on improving outcomes.

<b><i>Introduction:</i></b> Patients often experience delirium at the end of life. Benzodiazepine use may be associated with an increased risk of developing delirium. Alternate medications used in conjunction with benzodiazepines may serve as an independent precipitant of delirium. The aim is to understand the role of benzodiazepines in precipitating delirium and advanced mortality in palliative care population at the end of life. <b><i>Methods:</i></b> A retrospective medical chart review was conducted at a hospice and palliative care inpatient unit between the periods of June 2017–December 2017 and October 2017–November 2018. It included patients in hospice and palliative care inpatient units who received a benzodiazepine and those who did not. Patient characteristics, as well as Palliative Performance Scale score, diagnosis, and occurrence of admission, terminal, and/or recurrent delirium, were collected and analyzed. <b><i>Results:</i></b> Use of a benzodiazepine was not significantly associated with overall mortality nor cause-specific death without terminal delirium rate. However, it was significantly associated with higher cause-specific death with terminal delirium rate and a higher recurrent delirium rate. <b><i>Discussion:</i></b> This retrospective chart review suggests an association between benzodiazepine use and specific states of delirium and cause-specific death. However, it does not provide strong evidence on the use of this drug, especially at the end of life, as it pertains to the overall mortality rate. Suggested is a contextual approach to the use of benzodiazepines and the need to consider Palliative Performance Scale score and goals of care in the administration of this drug at varying periods during patient length of stay.

The Impact

Introduction: Studies have demonstrated that aphasia may negatively impact morbidity and mortality among ischemic stroke (IS) patients. However, the association between post-stroke aphasia and readmission with infection (RI) is poorly understood. We sought to assess the impact of aphasia on post-stroke RI. We hypothesized that aphasic patients are at increased risk of infection in the 30-day post-stroke period. Methods: We performed retrospective chart review of the Mount Sinai Hospital IS patients with 30-day all cause readmission from January 2016 - December 2019. All variables were abstracted from the index admission (IA) electronic medical records except for aspects related to the readmission (RA). Aphasia was present if a neurologist diagnosed the patient with acquired language dysfunction during IA. We performed chi square and logistic regression analyses to compare readmitted patients with and without aphasia at IA. Our fully adjusted model controlled for age, sex, medical comorbidities, NIHSS ≥ 8, IA LOS > 7, IA infection, discharge to facility. We completed all analyses with SPSS. Results: During IA, 36% (n=42) were diagnosed with aphasia. At IA, there were no significant differences in age (dichotomized at 65), sex, or medical comorbidities between aphasic and non-aphasic cohorts. However, more aphasic patients had admission NIHSS ≥ 8 (89% vs 35%, p<0.0001), LOS > 7 (76% vs 42%, p=0.0004), discharge to facility (79% vs 49%, p=0.0016), and RI (52% vs 19%, p=0.002). The presence of aphasia predicted RI in both unadjusted (OR=4.6, p<0.001) and adjusted (OR= 3.3, p=0.014) multivariate analyses. The Kappa inter-reliability ranged from 0.7-1.0 for the key variables included in our adjusted model. Conclusions: The adjusted odds of 30-day readmission with infection were significantly greater in those with diagnosis of aphasia at the time of index admission compared to those without. Our study provides preliminary evidence that the presence of aphasia may have negative consequences on a patient’s health beyond the language disturbance. Further study is needed to better understand the reasons and risk reduction strategies in this vulnerable population.

Dissecting Aneurysms

Introduction : Acute dissecting aneurysms are among the uncommon causes of subarachnoid hemorrhage. Established endovascular treatment options include parent artery occlusion and stent‐assisted coiling, but appear to be associated with an increased risk of ischemic stroke. reconstruction of the vessels with flow diverters is an alternative therapeutic option. Methods : This is a retrospective analysis of 53 consecutive acutely ruptured dissecting aneurysms treated with flow diverters. The primary end point was favorable aneurysm occlusion, defined as OKM C1‐3 and D . Secondary end points were procedure‐related complications and clinical outcome. Results : 23 aneurysms (43.4%%) arose from the intradural portion of the vertebral artery, 10 (18.8%) were located on the posterior inferior cerebellar artery and 3 (5.6%) posterior cerebral artery, 7 (13.2%) MCA, (18.8%) ICA . 45 aneurysms presented by SAH while 8 presented by Ischemic manifestation. Flow diverter placement was technically successful in all cases . immediate postoperative rerupture occurred in two case (3.7%), thromboembolic complications in 3 cases (5.7%). Median clinical follow‐up was 640 days and median angiographic follow‐up was 690 days. ten patients (18.9%) with poor‐grade subarachnoid hemorrhage died in the acute phase. Favorable clinical outcome (modified Rankin scale ≤2) was observed in 27 of 53 patients (51%) and a moderate outcome (modified Rankin scale 3/4) was observed in 12 of 53 patients (22.6%). All aneurysms showed complete occlusion at follow‐up. Conclusions : Flow diverters might be a feasible, alternative treatment option for acutely symptomatic dissecting aneurysms and may effectively prevent rebleeding in ruptured aneurysms.

Objective: To evaluate the functional outcome of individuals with transfemoral and contralateral transtibial amputations secondary to peripheral vascular disease.Methods: A retrospective chart review followed by phone interview. The primary outcome measures were the discharge 2-minute walk test, Frenchay Activities Index, and the Houghton Scale.Results: There were 31 dysvascular individuals identified to have a combination of transfemoral/transtibial (TF/TT) amputation admitted to our institution for rehabilitation from February 1998 to June 2007. The mortality at follow up was 68%. There were eight surviving amputees. The average 2-minute walk test score was 31.9 m at the time of discharge from our inpatient program. Of these, the average Frenchay Activities Index was 15.3. The average Houghton Scale score for use of the transtibial prosthesis alone was 2.1. The average Houghton Scale score for use of both prostheses was 1.5. Comparisons between groups based on initial amputation level revealed a significant difference of being fitted with a transfemoral prosthesis. Those whom initially had a TT amputation were less likely to ultimately be fitted with a TF prosthesis ( X21,n=31 = 4.76, p < 0.05).Conclusion: The overall functional outcome of individuals with a combination of TF/TT amputation due to dysvascular causes is poor. These individuals have a low level of ambulation, activity, and prosthetic use.

Object The authors sought to determine frequency, risk factors, and impact on outcome of asymptomatic cerebral infarction due to vasospasm after subarachnoid hemorrhage (SAH). Methods The authors prospectively studied 580 patients with SAH admitted to their center between July 1996 and May 2002. Delayed cerebral ischemia (DCI) from vasospasm was defined as 1) a new focal neurological deficit or decrease in level of consciousness, 2) a new infarct revealed by follow-up CT imaging, or both, after excluding causes other than vasospasm. Outcome at 3 months was assessed using the modified Rankin Scale. Results Delayed cerebral ischemia occurred in 121 (21%) of 580 patients. Of those with DCI, 36% (44 patients) experienced neurological deterioration without a corresponding infarct, 42% (51 patients) developed an infarct in conjunction with neurological deterioration, and 21% (26 patients) had a new infarct on CT without concurrent neurological deterioration. In a multivariate analysis, risk factors for asymptomatic DCI included coma on admission, placement of an external ventricular drain, and smaller volumes of SAH (all p ≤ 0.03). Patients with asymptomatic DCI were less likely to be treated with vasopressor agents than those with symptomatic DCI (64 vs 86%, p = 0.01). After adjusting for clinical grade, age, and aneurysm size, the authors found that there was a higher frequency of death or moderate-to-severe disability at 3 months (modified Rankin Scale Score 4–6) in patients with asymptomatic DCI than in patients with symptomatic DCI (73 vs 40%, adjusted odds ratio 3.9, 95% confidence interval 1.3–12.0, p = 0.017). Conclusions Approximately 20% of episodes of DCI after SAH are characterized by cerebral infarction in the absence of clinical symptoms. Asymptomatic DCI is particularly common in comatose patients and is associated with poor outcome. Strategies directed at diagnosing and preventing asymptomatic infarction from vasospasm in patients with poor-grade SAH are needed.

Abstract BACKGROUND Hydrocephalus after nontraumatic subarachnoid hemorrhage (SAH) is a common sequela that may require the placement of ventriculoperitoneal shunts (VPS). Adjustable-pressure valves (APVs) are being widely used in this situation though more expensive than differential-pressure valves (DPVs). OBJECTIVE To compare outcomes between APV and DPV in SAH-induced hydrocephalus. METHODS We performed a retrospective chart review of patients with nontraumatic SAH who underwent VPS placement for the treatment of hydrocephalus after SAH, between July 2007 and December 2016. Patients were classified according to the type of valve (APV vs DPV). We evaluated factors that could predict the type of valve used, outcomes in VPS revision/replacement rate, and complications. RESULTS A total of 66 patients underwent VPS placement who were equally distributed into the 2 groups of valves. VPS failure with the need for revision/replacement occurred in 13 (19.7%) cases. Ten (30.3%) patients with DPV had a VPS failure, while 3 (9.1%) patients with an APV had a similar failure with the need for revision/replacement (P = .03). VPS placement before discharge during the initial hospitalization (P = .02) was statistically significant associated with the use of a DPV, while the reason of external ventricular drain (EVD) failure (P = .03) was associated with the use of an APV. CONCLUSION APVs had a lower rate of surgical revisions compared to DPVs. Early placement of VPS was associated with the use of a DPV. The need for EVD replacement due to EVD infection or malfunction was associated with higher rates of APV use.

Object Intraoperative rerupture during open surgical clipping of cerebral aneurysms in subarachnoid hemorrhage (SAH) is a relatively frequent and potentially catastrophic occurrence. Patients who suffer rerupture have been shown to have worse outcomes at discharge compared with those who do not have rerupture. Perioperative injury likely plays a large part in the clinical worsening of these patients. However, due to the increased vessel manipulation and repeat exposure to acute hemorrhage, it is possible that secondary injury from increased incidence of vasospasm also contributes. Identifying an increased rate of vasospasm in these patients would justify early aggressive treatment with measures to prevent delayed cerebral ischemia. The authors investigated whether patients who suffer intraoperative rerupture during surgical treatment of ruptured cerebral aneurysms are at increased risk of developing vasospasm. Methods Five hundred consecutive patients treated with open surgical clipping for SAH were reviewed, and clinical and imaging data were collected. Angiographic vasospasm was defined as vessel narrowing believed to be consistent with vasospasm on angiography. Symptomatic vasospasm was defined as angiographic vasospasm in the setting of a clinical change attributable to vasospasm. Rates of angiographic and symptomatic vasospasm among patients with and without intraoperative rerupture were compared. Results There were no significant differences between the groups with and without rupture with respect to age, sex, modified Fisher grade, history of hypertension, or smoking. The group with intraoperative rupture had more patients with Hunt and Hess Grade I. Angiographic vasospasm was noted in 279 (66%) of the 425 patients without rerupture compared with 49 (65%) of the 75 patients with rerupture (p = 1.0, Fisher's exact test). Symptomatic vasospasm was noted in 154 (36%) of the 425 patients without rerupture, compared with 31 (41%) of the 75 patients with rerupture (p = 0.44, Fisher's exact test). In multivariate analysis, higher modified Fisher grade was significantly predictive of vasospasm, whereas older age and male sex were protective. Conclusions This study found no significant influence of intraoperative rerupture during open surgical clipping on the rate of angiographic or symptomatic vasospasm. Brief exposure to acute hemorrhage and vessel manipulation associated with rerupture events did not affect the rate of vasospasm. Risk of vasospasm was related to increased modified Fisher grade, and inversely related to age and male sex. These results do not justify early, targeted vasospasm therapy in patients with intraoperative rerupture.
