Abstract
BACKGROUND We aimed to investigate the association between DNA-methylation biological age (B-age) calculated as age acceleration (ageAcc) and key aneurysmal subarachnoid haemorrhage (aSAH) complications such as vasospasm, delayed cerebral ischaemia (DCI), poor outcome, and mortality. METHODS We conducted a prospective study involving 277 patients with aSAH. B-age was determined in whole blood samples using five epigenetic clocks: Hannum's, Horvath's, Levine's and both versions of Zhang's clocks. Age acceleration was calculated as the residual obtained from regressing out the effect of C-age on the mismatch between C-age and B-age. We then tested the association between ageAcc and vasospasm, DCI and 12-month poor outcome (mRS 3-5) and mortality using linear regression models adjusted for confounders. RESULTS Average C-age was 55.0 years, with 66.8% being female. Vasospasm occurred in 143 cases (51.6%), DCI in 70 (25.3%) and poor outcomes in 99 (35.7%), with a mortality rate of 20.6%. Lower ageAcc was linked to vasospasm in Horvath's and Levine's clocks, whereas increased ageAcc was associated with 12-month mortality in Hannum's clock. No significant differences in ageAcc were found for DCI or poor outcome at 12 months with other clocks. CONCLUSIONS Our study indicates that B-age is independently associated with vasospasm and 12-month mortality in patients with aSAH. These findings underscore the potential role of epigenetics in understanding the pathophysiology of aSAH-related complications and outcomes.

Aggressive Intraoperative Cisternal Clot Removal After Clipping Aneurismal Subarachnoid Hemorrhage in Elderly Patients. World Neurosurg 2020; 147:e482-e490. [PMID: 33383198 DOI: 10.1016/j.wneu.2020.12.102] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 12/17/2020] [Accepted: 12/18/2020] [Indexed: 12/28/2022]
Abstract
BACKGROUND Aneurysmal subarachnoid hemorrhage (aSAH) in the elderly often has a poor prognosis even after surgical treatment in the acute phase. Additionally, subarachnoid clots are the strongest predictors of cerebral vasospasm and tend to be thicker and heavier due to cerebral atrophy. We aimed to compare the conventional surgical treatment in such patients and identify the independent predictors of a favorable outcome after aggressive surgical clot removal. METHODS We included 40 patients with aSAH aged 70 or older. Each patient underwent aneurysmal clipping. We used the modified Rankin Scale to assess the primary outcome of neurologic status at discharge. We performed univariate analysis using the following factors: sex, age, neurologic, and general medical condition, radiographic data, aneurysm location, treatment approach, and timing of the aneurysm surgery. We divided the patients into irrigation and nonirrigation groups. We focused mainly on subarachnoid clots and analyzed them semiquantitatively using computed tomography. RESULTS Clot removal was significantly greater in the irrigation group (n = 21) than in the nonirrigation group (n = 19). The period of intrathecal drainage was significantly shorter in the irrigation group (P = 0.002). The rate of occurrence of new low-density areas on CT scans was higher in the nonirrigation group. Outcomes were better in the irrigation group (P = 0.010). CONCLUSIONS In elderly patients with aSAH in the acute phase, aggressive surgical clot removal after clipping showed favorable outcomes by facilitating early out-of-bed mobilization.

Comparison of Aggressive Surgical Treatment and Palliative Treatment in Elderly Patients with Poor-Grade Intracranial Aneurysmal Subarachnoid Hemorrhage. BIOMED RESEARCH INTERNATIONAL 2018; 2018:5818937. [PMID: 29998135 PMCID: PMC5994574 DOI: 10.1155/2018/5818937] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/08/2018] [Accepted: 04/19/2018] [Indexed: 12/29/2022]
Abstract
Objective To compare the current treatment approach in elderly patients with poor-grade aneurysmal subarachnoid hemorrhage (SAH) and identify the independent predictors of the outcome after aggressive surgical treatment. Method This prospective, multicenter cohort study included 104 poor-grade aneurysmal SAH elderly patients, 60 years or older, treated in our institution from October 2010 to March 2013. Patients were grouped according to three treatment arms. Neurological outcome was assessed using the Glasgow Outcome Scale (GOS) at baseline and at a 12-month follow-up. Univariate and multivariate analysis were performed using the following factors: sex, age, smoking history, breathing ability, alcohol consumption, cerebral hernia, aneurysm location, aneurysm diameter, WFNS grade, CT Fisher grade, treatment approach, and the timing of the aneurysm surgery. Results At the 12-month follow-up, patients in the coiling group and clipping group had better prognosis than patients in the palliative treatment group. Univariate analysis confirmed that the treatment approach, WFNS grade, CT Fisher grade, and age are critical factors for neurological outcomes in poor-grade SAH. Multivariate analysis indicated that WFNS grade V, CT Fisher grades 3-5, and palliative treatment were independent predictors of poor prognoses. Conclusion Aggressive surgical treatment improves the prognoses in poor-grade aneurysm elderly patients with SAH. Elderly Patients of WFNS grade IV and CT Fisher grades 1-2 are more likely to have a better outcome.

A Comparison of Computed Tomography-Based Scales with and without Consideration of the Presence or Absence of Intraventricular Hemorrhage in Patients with Aneurysmal Subarachnoid Hemorrhage. World Neurosurg 2018; 114:e926-e937. [PMID: 29588235 DOI: 10.1016/j.wneu.2018.03.117] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2017] [Revised: 03/16/2018] [Accepted: 03/16/2018] [Indexed: 11/20/2022]
Abstract
OBJECTIVE There has been controversy as to whether intraventricular hemorrhage (IVH) after aneurysmal subarachnoid hemorrhage (SAH) contributes to angiographic cerebral vasospasm (aCV) and delayed cerebral ischemia (DCI). Computed tomography-based SAH scales that did and did not consider IVH were compared in terms of ability to predict aCV, DCI, and outcome. METHODS We reviewed 390 patients with ruptured aneurysms who had been treated surgically by day 3 by the same surgeon (T.I.). aCV was graded as 0-4. Outcome at 6 months was classified using the Glasgow Outcome Scale. Inagawa SAH grades and scores, for which only SAH was evaluated, were compared with scales that evaluated both SAH and IVH (Fisher, Claassen, and Frontera grades, and Hijdra score). The area under the receiver operating characteristic curve was calculated to compare severe aCV (grade 3-4), DCI, or poor outcome (Glasgow Outcome Scale score 1-3). RESULTS The Inagawa grade showed constant and significant intergrade differences in both aCV and DCI. The Inagawa grade area under the receiver operating characteristic curve values were highest among the scales examined. In the Fisher, Claassen, and Frontera grades, IVH was unlikely to be related to aCV and DCI. There was no significant difference in aCV grade or DCI occurrence between the Inagawa and Hijdra scores. In contrast, the presence of IVH was significantly associated with poor outcome. CONCLUSIONS In patients with aneurysmal SAH, IVH is an important factor affecting patient outcome, whereas computed tomography-based SAH scales that do not consider IVH are superior to scales that do consider it for prediction of aCV or DCI.

Abstract
Introduction Cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH) is a major cause of mortality and morbidity. Despite various treatment modalities, the optimal management of vasospasm remains elusive. In this regard; we undertook a prospective, randomized controlled study to evaluate the effectiveness of lumbar cerebrospinal fluid drainage (LCSFD) for prevention of cerebral vasospasm and its sequelae. Materials and Methods Patients with aneurysmal SAH who met the inclusion criteria were randomized into two groups - Group I (30 patients) underwent LCSFD whereas Group II (30 patients) did not undergo LCSFD. All patients underwent aneurysmal clipping. Both the groups received standard neurosurgical treatment except for LCSFD. The outcome was measured in terms of (1) clinically evident vasospasm; (2) vasospasm-related cerebral infarction; (3) condition of the patient at the time of discharge; and (4) Glasgow outcome score (GOS) at 1- and 3-month follow-up. Results LCSFD conferred a statistically significant benefit reducing the incidence of clinical vasospasm from 63% (in non-LCSFD group) to 30% (in LCSFD group) (P = 0.01) and incidence of vasospasm-related cerebral infarction from 53% (in non-LCSFD group) to 20% (in LCSFD group) (P = 0.007). Incidence of vasospasm was quantitatively lower in LCSFD group across all Hunt and Hess grades; however, it was statistically significant in SAH Grade III (P = 0.008). Mean duration of hospital stay was slightly lower in LCSFD group compared to non-LCSFD group; however, it did not reach statistical significance. A higher incidence of meningitis in LCSFD group was not statistically significant. A higher GOS was observed in LCSFD group at 1- and 3-month follow-up as compared to non-LCSFD group. Conclusion Drainage of CSF through a lumbar drain following aneurysmal SAH caused a statistically significant reduction in the incidence of clinical and radiological vasospasm and its sequelae. It also shortens the overall duration of hospital stay and improves the outcome as evidenced by a better GOS score at 1- and 3-month follow-up. The results of this prospective, randomized study establish the efficacy of LCSFD in prevention of vasospasm following aneurysmal SAH.

Abstract
OBJECTIVE
Early rehabilitation is effective in an array of acute neurological disorders but it is not established as part of treatment guidelines after aneurysmal subarachnoid hemorrhage (aSAH). This may in part be due to the fear of aggravating the development of cerebral vasospasm, which is the most feared complication of aSAH. The aim of this study was to evaluate the effect of early rehabilitation and mobilization on complications during the acute phase and within 90 days after aSAH.
METHODS
This was a prospective, interventional study that included patients with aSAH at the neuro-intermediate ward after aneurysm repair. The control group received standard treatment, whereas the early rehab group underwent early rehabilitation and mobilization in addition to standard treatment. Clinical and radiological characteristics of patients with aSAH, progression in mobilization, and treatment variables were registered. The frequency and severity of cerebral vasospasm, cerebral infarction acquired in conjunction with the aSAH, and acute and chronic hydrocephalus, as well as pulmonary and thromboembolic complications, were compared between the 2 groups.
RESULTS
Clinical and radiological characteristics of patients with aSAH were similar between the groups. The early rehab group was mobilized beginning on the first day after aneurysm repair. The significantly quicker and higher degree of mobilization in the early rehab group did not increase complications. Clinical cerebral vasospasm was not as frequent in the early rehab group and it also tended to be less severe. Each step of mobilization achieved during the first 4 days after aneurysm repair reduced the risk of severe vasospasm by 30%. Acute and chronic hydrocephalus were similar in both groups, but there was a tendency toward earlier shunt implantation among patients in the control group. Pulmonary infections, thromboembolic events, and death before discharge or within 90 days after the ictus were similar between the 2 groups.
CONCLUSIONS
Early rehabilitation of patients after aSAH is safe and feasible. The earlier and higher degree of mobilization does not increase neurosurgical complications. Rather, the frequency and severity of cerebral vasospasm following aSAH are alleviated and are not aggravated by early rehabilitation.

Risk Factors for Cerebral Vasospasm Following Aneurysmal Subarachnoid Hemorrhage: A Review of the Literature. World Neurosurg 2015; 85:56-76. [PMID: 26342775 DOI: 10.1016/j.wneu.2015.08.052] [Citation(s) in RCA: 69] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2015] [Revised: 08/17/2015] [Accepted: 08/18/2015] [Indexed: 12/13/2022]
Abstract
OBJECTIVE To examine the literature on risk factors for cerebral vasospasm (CV), one of the most serious complications following aneurysmal subarachnoid hemorrhage (SAH), with special reference to the definition of CV. METHODS Using standard search engines, including PubMed, the medical literature on risk factors for CV after SAH was reviewed, and the best definition representative of CV was searched. RESULTS Severe SAH evident on computed tomography scan was the only consistent risk factor for CV after SAH. Effects of risk factors on CV, including age, clinical grade, rebleeding, intraventricular or intracerebral hemorrhage on computed tomography scan, acute hydrocephalus, aneurysm site and size, leukocytosis, interleukin-6 level, and cardiac abnormalities, appeared to be associated with the severity of SAH rather than each having a direct effect. Cigarette smoking, hypertension, and left ventricular hypertrophy on electrocardiogram were associated with CV without any relationship to SAH severity. With regard to parameters representative of CV, the grade of angiographic vasospasm (i.e., the degree of arterial narrowing evident on angiography) was the most adequate. Nevertheless, few reports on the risk factors associated with angiographic vasospasm grade have been reported to date. CONCLUSIONS Severe SAH evident on computed tomography scan appears to be a definite risk factor for CV after SAH, followed by cigarette smoking, hypertension, and left ventricular hypertrophy on electrocardiogram. To understand the pathogenesis of CV, further studies on the relationships between risk factors, especially factors not related to the severity of SAH, and angiographic vasospasm grade are necessary.

Abstract
We studied the risk factors associated with cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH). The subjects were 370 patients with ruptured aneurysms who fulfilled all of the following criteria: admission by day 2 after onset, operation performed by day 3 by the same surgeon (T.I.), Hunt-Hess grade I–IV, availability of bilateral carotid angiograms acquired by day 2 and repeated between days 7 and 9. The demographic, clinical, radiographic, surgical, laboratory, and electrocardiographic data were analyzed for angiographic vasospasm (AV), symptomatic vasospasm (SV), and cerebral infarction on computed tomography (CT) scan. Both CT-evident SAH and AV were graded as 0–IV. Among the 370 patients, AV grade III–IV, SV, and cerebral infarction occurred in 26%, 24%, and 20%, respectively. Univariate analysis showed that Hunt-Hess grade III–IV, SAH grade III–IV, intracerebral or/and intraventricular hemorrhage, rebleeding, cigarette smoking, hypertension, alcohol intake, leukocytosis, hyperglycemia, and electrocardiographic QTc prolongation, left ventricular hypertrophy (LVH), and ST depression were significantly related to at least one of AV grade III–IV, SV, or cerebral infarction. Multivariate analysis showed that SAH grade III–IV was the most important risk factor for vasospasm followed by LVH on electrocardiogram, cigarette smoking, and hypertension. AV grade III– IV, SV, and cerebral infarction occurred in 57%, 54%, and 39% of the 46 smokers with LVH, and in 43%, 49%, and 35% of the 68 patients who had both LVH and hypertension, respectively. CT-evident SAH, LVH, cigarette smoking, and hypertension are associated with vasospasm. In smokers or hypertensive patients, premorbid LVH appears to predict much more severe vasospasm.

Abstract
Aneurysmal subarachnoid hemorrhage occurs in approximately 30,000 persons in the United States each year. Around 30 percent of patients with aneurysmal subarachnoid hemorrhage suffer from cerebral ischemia and infarction due to cerebral vasospasm, a leading cause of treatable death and disability following aneurysmal subarachnoid hemorrhage. Methods used to predict, diagnose, and manage vasospasm are the topic of recent active research. This paper utilizes a comprehensive review of the recent literature to address controversies surrounding these topics. Evidence regarding the effect of age, smoking, and cocaine use on the incidence and outcome of vasospasm is reviewed. The abilities of different computed tomography grading schemes to predict vasospasm in the aftermath of subarachnoid hemorrhage are presented. Additionally, the utility of different diagnostic methods for the detection and visualization of vasospasm, including transcranial Doppler ultrasonography, CT angiography, digital subtraction angiography, and CT perfusion imaging is discussed. Finally, the recent literature regarding interventions for the prophylaxis and treatment of vasospasm, including hyperdynamic therapy, albumin, calcium channel agonists, statins, magnesium sulfate, and endothelin antagonists is summarized. Recent studies regarding each topic were reviewed for consensus recommendations from the literature, which were then presented.

Abstract
Objective Shunt-dependent chronic hydrocephalus (SDCH) is known to be a major complication associated with aneurysmal subarachnoid hemorrhage (aSAH). Old age is known to be one of numerous factors related to the development of SDCH. This study investigated whether postoperative cisternal drainage affects the incidence of SDCH and clinical outcome in elderly patients with aSAH. Methods Fifty-nine patients participated in this study. All patients underwent aneurysmal clipping with cisternal cerebrospinal fluid (CSF) drainage. Clinical variables relevant to the study included age, sex, location of ruptured aneurysm, CT finding and clinical state on admission, clinical outcome, and CSF drainage. We first divided patients into two groups according to age (<70 years of age and ≥70 years of age) and compared the two groups. Secondly, we analyzed variables to find factors associated with SDCH in both groups (<70 years of age and ≥70 years of age). Results Of 59 patients, SDCH was observed in 20 patients (33.9 %), who underwent shunt placement for treatment of hydrocephalus. Forty seven percent of cases of acute hydrocephalus developed SDCH. In the elderly group (≥70 years of age), the duration and amount of CSF drainage did not affect the development of chronic hydrocephalus. Conclusion In elderly patients, although the incidence of SDCH was significantly higher, clinical outcome was acceptable. The duration and the amount of cisternal drainage did not seem to be related to subsequent development of chronic hydrocephalus within elderly patients aged 70 or older.

Abstract
Abstract
BACKGROUND:
Vasospasm is the major cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage. It is well known that the vasoreactivity decreases with advancing age, but it is not well investigated in a large patient cohort whether, as a consequence, the incidence of vasospasm is lower in elderly patients.
OBJECTIVE:
To investigate whether transcranial Doppler vasospasm, delayed ischemic neurological deficits, and vasospasm-associated ischemic lesions are less frequent in older patients.
METHODS:
Seven hundred fifty-eight patients who suffered from subarachnoid hemorrhage were included in this study. Clinical presentation, Hunt and Hess score, Fisher grade, incidence of vasospasm, neurological deficits and ischemic lesions on radiographic imaging, transcranial Doppler blood flow velocities, medical complications, and outcome were registered.
RESULTS:
Four hundred seventy-eight patients < 60 years of age and 280 patients ≥ 60 years of age were identified; 55.2% of the younger and 25.7% of the older age group developed post-hemorrhagic vasospasm (P < .001). Older patients developed less vasospasm (P = .00), fewer neurological deficits (P < .001), and fewer ischemic lesions on computed tomography imaging (P = .06). On the other hand, older patients had significantly worse outcomes than younger patients (P = .01) and more frequently died of medical complications (P = .01).
CONCLUSION:
Vasospasm, delayed ischemic neurological deficits, and vasospasm-associated ischemic lesions are more likely to occur in patients < 60 years of age than in older patients. The lower incidence of vasospasm and vasospasm-related ischemia in the elderly patient does not translate into better outcome because of the higher rate of fatal medical complications in patients ≥ 60 years of age.

Abstract
Abstract
BACKGROUND:
Subarachnoid hemorrhage (SAH) from a ruptured intracranial aneurysm is a devastating disease with high mortality and morbidity. The incidence of SAH increases with advancing age.
OBJECTIVE:
To determine whether age is an independent predictor of angiographic vasospasm, delayed ischemic neurological deficits (DINDs), or abnormal transcranial Doppler (TCD) measurements in patients with aneurysmal subarachnoid hemorrhage.
METHODS:
Data from CONSCIOUS-1 (Clazosentan to Overcome Neurological Ischemia and Infarct Occurring After Subarachnoid Hemorrhage study), a dose-finding study of clazosentan, were used. Data on angiographic vasospasm, DINDs, and TCD abnormalities were prospectively recorded as well as baseline characteristics and treatment data. Patient age was considered in 3 ways: as a continuous variable, dichotomized at age 65 years, and categorized by decade. Age was investigated as the main variable, whereas other possible confounding variables were adjusted for in the multiple logistic regression modeling with each of 3 dichotomized vasospasm outcome measures, presence or absence of angiographic vasospasm, DINDs, and TCD abnormalities as the dependent variable.
RESULTS:
The proportions of patients with angiographic vasospasm, DINDs, and TCD abnormalities were 45%, 19%, and 81%, respectively. Age, whether considered as a continuous, dichotomous, or a categorical variable, was not significantly associated with angiographic vasospasm, DINDs, or abnormal TCD measurements.
CONCLUSION:
Age does not seem to be a significant predictor for cerebral vasospasm after subarachnoid hemorrhage.

Timing of symptomatic vasospasm in aneurysmal subarachnoid hemorrhage: the effect of treatment modality and clinical implications. J Stroke Cerebrovasc Dis 2010; 19:110-5.

Abstract
A better prediction of the time course of symptomatic vasospasm (SVSP) might have a significant impact on the management and prevention of delayed neurologic ischemic deficit (DIND). We studied the influence of the treatment for ruptured aneurysm on SVSP timing. We retrospectively analyzed data of consecutive patients with aneurysmal subarachnoid hemorrhage (aSAH) admitted in our center between 1999 and 2005, treated within 72 hours of the rupture by surgical clipping or endovascular coiling and in accordance with our neuroscience unit protocol. We analyzed the presence of SVSP and recorded the timing of occurrence after the aneurysmal repair intervention. Data on demographics, premorbid conditions, time elapsed from the subarachnoid hemorrhage onset and intervention, and clinical and radiologic characteristics at admission were collected. The first occurrence of postintervention SVSP was recorded and compared between the 2 treatment groups using a proportional hazards regression model, including significant covariates. Of the 67 patients analyzed, 21 (31%) underwent endovascular coiling and 46 (69%) underwent surgical clipping. The baseline variables were similar in the 2 groups. The median time from the procedure to clinical vasospasm was 4 days in the coiled patients and 7 days in the clipped patients. In a proportional hazards model regression analysis including age, sex, Fisher and Hunt-Hess grades, time between onset to procedure, and intervention type, only intervention type emerged as a significant predictor of time to SVSP after intervention (likelihood ratio chi2 = 16.8; P < .00). Treatment modality of ruptured intracranial aneurysm may influence the timing of SVSP occurrence.

Abstract
Object
The aim of the study was to assess postprocedural neurological deterioration and outcome in patients older than 70 years of age in whom treatment was managed in an interdisciplinary context.
Methods
This prospective longitudinal study included all patients 70 years of age or older treated for ruptured cerebral aneurysm over 10 years (June 1997–June 2007). The population was composed of 64 patients. The neurovascular interdisciplinary team jointly discussed the early obliteration procedure for each aneurysm. Neurological deterioration during the postprocedural 2 months and outcome at 6 months were assessed during consultation according to the modified Rankin Scale (mRS) as follows: favorable (mRS score ≤ 2) and unfavorable (mRS score > 2).
Results
Aneurysm sac obliteration was performed by microvascular clipping in 34 patients (53.1%) and by endovascular coiling in 30 (46.9%). Postprocedural neurological deterioration occurred in 30 patients (46.9%), related to ischemia in 19 (29.7%), rebleeding in 1 (1.6%), and hydrocephalus in 10 (15.6%). At 6 months, the outcome was favorable in 39 patients (60.9%). By multivariate regression logistic analysis, the independent factors associated with unfavorable outcome were age exceeding 75 years (p = 0.005), poor initial grade (p < 0.0001), and the occurrence of ischemia (p < 0.0001).
Conclusions
The baseline characteristics of SAH in the elderly were only slightly different from those in younger patients. In the elderly, the interdisciplinary approach may be considered useful to decrease the ischemic consequences.

Abstract
Object
Vasospasm is a leading cause of morbidity and death following aneurysmal subarachnoid hemorrhage (SAH). It is important to predict which patients are at risk for vasospasm so that interventions can be made. There are several potential risk factors for vasospasm, one of which is age. However, the effect of age on vasospasm, particularly symptomatic vasospasm, remains controversial.
Methods
Three hundred ninety-one patients were retrospectively identified from a prospective observational database of patients with SAH who had been admitted to a single center. Demographic and clinical data were recorded, and cerebral angiograms obtained at admission and between 5 and 10 days later were compared. The relationship between age and angiographic and symptomatic vasospasms was examined using logistic regression techniques.
Results
Mild (86 patients), moderate (69 patients), severe (56 patients), and no angiographic vasospasms (180 patients) were documented by comparing admission and follow-up angiograms in each patient. Symptomatic vasospasm was identified in 69 patients (17.6%). Angiographic vasospasm was more frequent as age decreased. Except in patients < 30 years old, the frequency of symptomatic vasospasm also increased with decreasing age (p = 0.0001). After adjusting for variables known to be associated with vasospasm, an advanced age was associated with a reduced incidence of any angiographic vasospasm (OR 0.96, 95% CI 0.94–0.97), severe angiographic vasospasm (OR 0.96, 95% CI 0.95–0.98), and symptomatic vasospasm (OR 0.98, 95% CI 0.96–0.99).
Conclusions
Results in this study show that a younger age is associated with an increased incidence of angiographic and symptomatic vasospasm.

Abstract
Rupture of an intracranial aneurysm (ICA) remains a devastating complication associated with a high degree of morbidity and mortality. In the past 2 decades, older people were often excluded from active treatment on the unique basis of their chronological age. Recent developments of less-invasive techniques for the diagnosis and treatment of ruptured and unruptured ICAs suggest that this fatalistic attitude toward older patients should be reconsidered. Furthermore, taking into account the heterogeneity of the elderly population, the use of a comprehensive geriatric assessment approach, based on a multidisciplinary evaluation, appears particularly helpful in proposing the optimal treatment strategy for each older patient. This article reviews the geriatric features of epidemiological, physiopathological, as well as clinical and therapeutic aspects of ruptured and unruptured ICAs.

Abstract
OBJECT This study was performed to further elucidate technical and patient-specific risk factors for perioperative stroke in patients undergoing temporary arterial occlusion during the surgical repair of their aneurysms. METHODS One hundred twelve consecutive patients in whom temporary arterial occlusion was performed during surgical repair of an aneurysm were retrospectively analyzed. Confounding factors (inadvertent permanent vessel occlusion and retraction injury) were identified in six cases (5%) and these were excluded from further analysis. The demographics for the remaining 106 patients were analyzed with respect to age, neurological status, aneurysm characteristics, intraoperative rupture, duration of temporary occlusion, and number of occlusive episodes; end points considered were outcome at 3-month follow up and symptomatic and radiological stroke. CONCLUSIONS Overall 17% of patients experienced symptomatic stroke and 26% had radiological evidence of stroke attributable to temporary arterial occlusion. A longer duration of clip placement, older patient age, a poor clinical grade (Hunt and Hess Grades IV-V), early surgery, and the use of single prolonged clip placement rather than repeated shorter episodes were associated with a higher risk of stroke based on univariate analysis. Intraoperative aneurysm rupture did not affect stroke risk. On multivariate analysis, only poorer clinical grade (p = 0.001) and increasing age (p = 0.04) were significantly associated with symptomatic stroke risk.

Abstract
This report presents 74 consecutive cases of subarachnoid haemorrhage (SAH) in patients aged 70 years or older, compared with the 317 consecutive younger patients treated during the same period. An ultra-early surgical strategy for all SAH cases was used throughout the study period. Management outcome for all grades of elderly patients was independent in 38%, dependent in 14% and death in 49%. Surgical 3-month outcome of good grade elderly patients was independent 53%, dependent 19% and death 28%; and for poor grades was independent 35%, dependent 15% and death 50%. Elderly poor grade patients had similar outcome to younger patients, although good grade patients had better outcome in the younger group than the elderly group. Despite ultra-early surgery, rebleeding (<12 h of SAH) occurred in 9% of the elderly series. Aggressive, ultra-early treatment is likely to benefit elderly SAH patients, the potential benefit being greater for poor grade elderly patients.

Abstract
The influence of the treatment modalities (clipping/coiling) on the incidence of vasospasm and ischaemic infarction in aneurysm patients is still judged controversially. The purpose of this study was to analyse and compare retrospectively cerebral vasospasm and ischaemic infarction, as well as neurological deficits and outcome within a large population of clipped and coiled patients with ruptured and unruptured aneurysms. Within a 2-year period, a total of 144 interventions (53 clipping/91 coiling) entered the study. Daily bilateral transcranial Doppler sonographic monitoring was performed to observe vasospasm development. All cerebral computed tomography (cCT) and magnetic resonance imaging (MRI) scans were reviewed with respect to occurrence and localization of ischaemic infarctions. Focal neurological deficits were recorded and clinical outcome was evaluated using the Glasgow Outcome Scale. Statistical analysis included the use of multivariate logistic regression models to find determinants of vasospasm, ischaemic infarction and neurological deficits. Altogether, vasospasm was detected after 77 (53.5%) interventions, 61.8% in females (P < 0.01). Clipped patients significantly more often exhibited vasospasms (69.8 vs. 44.0%, P < 0.005) and were treated 1 week longer at the intensive care unit (P < 0.005). Seventy-seven patients (53.5%) developed ischaemic infarctions, 62.3% after clipping and 48.4% after coiling (P > 0.05). In the multivariate analysis, aneurysm-rupture was the strongest predictor for vasospasm and vasospasm was the strongest predictor for infarction. Neurological deficits at discharge (46.5%) were independent of treatment modality, the same applied for the mean Glasgow Outcome Scores. There was no significant difference in mortality between surgical and endovascular treatment (9.4 vs. 12.1%). Whilst the vasospasm incidence was significantly higher after surgical treatment, ischaemic infarctions were only slightly more frequent. The incidence of neurological deficits and clinical outcome was similar in both treatment groups.

Abstract
OBJECTIVE By use of serial magnetic resonance imaging (MRI), we prospectively investigated the incidence of and the risk factors associated with infarction caused by vasospasm with or without a delayed ischemic neurological deficit (DIND) in patients with subarachnoid hemorrhage (SAH). METHODS In 125 patients who underwent surgery for early aneurysms, postoperative MRI scans were obtained at four time points. We defined an infarct from vasospasm as a new lesion not present on the initial MRI within 3 days after SAH and therefore not attributable to primary brain damage or surgical complications. RESULTS Overall, symptoms of infarction (i.e., DIND) occurred in 38% of patients (48 of 125); DIND with a new infarct on MRI was evident in 34% (43 patients), whereas 4% (5 patients) showed no new lesion but had a DIND. However, 29 patients (23%) showed a new infarct but no DIND on MRI studies (asymptomatic infarction). Asymptomatic ischemic lesions due to vasospasm tended to involve noneloquent brain areas in the territory of intraparenchymal perforators. Multivariate analysis identified variables associated with symptomatic infarction to be of poor SAH grade, advanced age of the patient, angiographic findings of vasospasm, multiple cortical infarcts on MRI studies consistent with vasospasm, and chronic hydrocephalus. CONCLUSION Analysis of the data confirmed the occurrence of asymptomatic infarcts due to vasospasm. These infarcts often developed in noneloquent areas representing perforator territory. MRI investigation of vasospastic lesions referable to intraparenchymal vessels such as perforators complements the study of extraparenchymal major vessel vasospasm in patients with SAH by computed tomographic angiography.

Abstract
SUMMARY Endovascular treatment of intracranial aneurysms using platinum coils was performed in 26 patien with age over 70 years. The patients ranged from 70 to 86 years old (mean 77.5). Preoperative World Federation of Neurological Surgeons (WFNS) scale revealed that 6 patients were in grade I, 5 in grade II, 2 in grade III, 12 in grade IV, and 1 in grade V. The location of aneurysms are as follows; 10 were in the internal carotid artery, 7 in the anterior cerebral artery, 1 in the middle cerebral artery, and 8 in the vertebro- basilar system. Intra-aneurysmal occlusion was accomplished in 25 patients, resulting in 6 complete occlusion (24%), 3 neck remnant (12%), 11 body filling (44%), and both of neck remnant and body filling in 5 (20%). In one patient with vertebral artery union aneurysm, the parent artery was occluded just proximal to the aneurysm. Eleven of 13 patients with good clinical grade (grade I, II, and III) resulted in good clinical outcome, whereas 11 of 13 patients with poor clinical grade (grade IV and V) showed poor outcome. Periprocedural complications such as thromboembolism and intra-procedural rupture occurred in 5 patients (19.2%). Each of the complications was attributed to severe atherosclerotic changes of parent arteries. Symptomatic cerebral vasospasm occurred in only one patient (3.8%). In conclusion, endovascular coil emboilization is a useful therapeutic alternative for treating ruptured intracranial aneurysms in patients over 70 years of age, especially in patients with good clinical grade (better than grade III).

Abstract
BACKGROUND AND PURPOSE The effects of aging on cerebral vasospasm after subarachnoid hemorrhage (SAH) remain to be elucidated. The aim of this study was to clarify age-related differences of vasospasm and of papaverine reactivity in the responses of basilar arteries after SAH in rabbits. METHODS Rabbits receiving a single injection of arterial blood into the cisterna magna were divided into 3 groups: young (2 to 3 months old), adult (6 to 9 months old), and old (20 to 40 months old). Vertebrobasilar angiograms were obtained before SAH and 1, 2, 4, and 7 days after SAH. Papaverine was administrated selectively via the vertebral artery on day 2, and serial angiography was performed for up to 2 hours. Vessel structures were assessed with light microscopy on days 1, 2, 4, and 7 after SAH and at 10, 30, and 60 minutes after papaverine infusion. RESULTS Mortality from SAH in old rabbits was 40%, whereas that of young and adult rabbits was 0%. Angiograms revealed that SAH induced maximal constriction of the basilar arteries on day 2 in all age groups, and the constrictions were significantly increased with age at all time points investigated. The degree of dilatation of spastic basilar arteries after intra-arterial papaverine administration significantly decreased with age. Duration of the efficacy of papaverine became significantly shorter with age. Vessel diameter returned to the preinfusion value approximately 120, 60, and 30 minutes after infusion in young, adult, and old rabbits, respectively. Light microscopy in old rabbits showed luminal narrowing and corrugation of the internal elastic lamina not only in the basilar arteries but also in small arteries and intraparenchymal arterioles. CONCLUSIONS This study suggests that aging increases the degree of vasospasm in rabbits. The impaired reactivity to papaverine with aging might imply the early transition of the aged vessel to the papaverine-resistant chronic stage.

Abstract
BACKGROUND AND PURPOSE The feasibility of preventing vasospasm by intrathecal anterograde infusion of urokinase (UK) into the cisterna magna was studied in patients with recently ruptured aneurysms who had just undergone the placement of a Guglielmi detachable coil (GDC). METHODS Immediately after complete embolization with the use of GDC-10 coils, 15 patients with Hunt and Hess neurological grades III and IV received 60 000 IU of UK in normal saline through a microcatheter advanced into the cisterna magna. UK infusion was repeated once or twice over a period of 2 to 3 days according to a decision based on CT evidence of a subarachnoid clot remaining in the cisterns. Before administering the last UK infusion, we obtained CT confirmation of almost complete clearance of clots in the basal cisterns. RESULTS In all 15 patients, the microcatheter was advanced easily into the cisterna magna by use of the over-the-wire microcatheter technique. In 8 patients who received thrombolytic therapy within 24 hours of the ictus, there was almost complete clearance of the clot in the basal cisterns within 2 days of suffering the insult. When UK was injected at 24 to 48 hours after the insult, 7 patients manifested CT evidence of clearance at the latest 4 days after suffering the insult. In all 15 patients, CT scans obtained within 24 hours of the final UK administration showed complete resolution of clots in the basal cistern and almost complete resolution of clots in the basal interhemispheric fissure and bilateral proximal sylvian fissures. Although one patient developed a transient neurological deficit, no patients manifested permanent delayed neurological deficits as a result of vasospasm. Outcome assessment according to the Glasgow Outcome Scale, no less than 3 months after GDC placement, revealed good recovery in all patients, and none developed hydrocephalus requiring a shunt procedure. CONCLUSIONS In patients with recently ruptured aneurysms, GDC placement followed by immediate intrathecal administration of UK from the cisterna magna may be a safe and reasonable means of preventing vasospasms and may result in improved treatment outcomes.

Abstract
OBJECTIVE Symptomatic vasospasm after subarachnoid hemorrhage (SAH) is associated with a high incidence of permanent disability and death. For early identification of patients who are at risk for poor outcome, we determined the predictors of outcome in patients with symptomatic vasospasm after SAH. DESIGN We retrospectively determined the prognostic value of clinical characteristics and computed tomographic scan both at admission and at the time of initiation of hypervolemic and hypertensive therapy. SETTINGS Neurosciences critical care unit at a University hospital. PATIENTS A total of 70 consecutive patients who developed symptomatic vasospasm after SAH. INTERVENTION Treatment with oral nimodipine, hypervolemic therapy, and hypertensive therapy. Angioplasty and intra-arterial papaverine were used in patients with vasospasm resistant to standard treatment. MEASUREMENTS AND MAIN RESULTS Poor outcome, defined as Glasgow Outcome Scale Score of 3-5 at 2 months or discharge, was observed in 32 (46%) patients. In the logistic regression analysis, a Glasgow Coma Scale (GCS) score of < or =11 (odds ratio, 11.0; 95% confidence interval, 3.6-39.3) and hydrocephalus (odds ratio, 4.3; 95% confidence interval, 1.2-18.2) at the time of initiation of hypervolemic and hypertensive therapy were significantly associated with poor outcome. Poor outcome was observed in 91% of the patients who had both a GCS score of < or =11 and hydrocephalus compared with 15% of patients with a GCS score of >11 and no hydrocephalus at the time of initiation of hypervolemic and hypertensive therapy. A GCS score of < or =11 was also independently associated with length of intensive care unit stay (F ratio = 18.0; p = .0011) and hospital stay (F ratio = 9.2; p = .0034) after initiation of hypervolemic and hypertensive therapy. CONCLUSIONS The results of this study suggest that outcome in patients with symptomatic vasospasm can be effectively predicted by routinely available information, including GCS score at the time of initiation of hypervolemic and hypertensive therapy. This information can be used for selection and stratification of patients in future treatment studies of patients with symptomatic vasospasm.

Abstract
BACKGROUND The purpose of this study was to investigate why elderly patients have poorer outcomes and to determine indications for surgery in elderly patients. METHODS One hundred fifty-four patients with intracranial aneurysms admitted to the Department of Neurosurgery, Showa University School of Medicine, from 1990 through 1996 were reviewed. The patients were classified by age into three groups (young group, middle-aged group, elderly group). RESULTS Forty-four patients (28.6%) were in the elderly group (mean age, 73 years). No difference in outcome was found between middle-aged and elderly patients if patients were stratified according to clinical grade. In addition, the main factors related to unfavorable outcomes in elderly patients were infection, organ failure, aneurysm rerupture before operation, and delayed ischemic deterioration. Elderly patients were more likely to experience rebleeding and have poor outcomes. CONCLUSIONS Our results suggest that elderly patients should have early surgery. Furthermore, we found that the presence of hypertension or atherosclerosis had no significant effect on outcome. We conclude that early surgical treatment of aneurysms is indicated for elderly patients with good clinical grades in the absence of organ failure.

Abstract
BACKGROUND With the aging of the population, surgery for ruptured intracranial aneurysms is increasing among the elderly. We sought to clarify the characteristics of chronic hydrocephalus following aneurysmal subarachnoid hemorrhage (SAH) in elderly patients. METHODS Of the 576 surgically treated patients, 289 were aged 59 years or younger, 169 were 60 to 69, and 118 were 70 years or older. The relationship between chronic hydrocephalus and the causative factors was analyzed for each age group. RESULTS Of the 576 patients, chronic hydrocephalus was observed in 215 (37%), with the incidence increasing significantly with age (p < 0.001) and being the highest in the oldest age group. In elderly patients, the incidence of chronic hydrocephalus was relatively high, even after mild SAH. The incidence of chronic hydrocephalus was high regardless of age in patients with severe SAH, such as in those with H&H grades III-IV, SAH grades III-IV, acute hydrocephalus, symptomatic vasospasm, and intraventricular hemorrhage, and in those with vertebro-basilar artery aneurysms. CONCLUSION In the elderly, the incidence of chronic hydrocephalus following SAH was significantly higher than in younger patients, even after mild SAH. In elderly patients, careful observation and individualized treatment are necessary even if SAH is mild.

Abstract
BACKGROUND AND PURPOSE The role of type of treatment on cerebral vasospasm occurrence after aneurysmal subarachnoid hemorrhage (SAH) has not been studied. Through multivariate analysis we determined the independent prognostic factors of the occurrence of symptomatic vasospasm following aneurysmal SAH in a study cohort of 244 patients undergoing either surgical or endovascular treatment. The prognostic factors of sequelae after aneurysmal SAH were studied as well. METHODS Symptomatic vasospasm was defined as the association of deterioration in a patient's neurological condition between 3 and 14 days after SAH with no other explanation and an increase in mean transcranial Doppler velocities of >120 cm/s. The prognostic factors were registered on admission and during the intensive care stay. RESULTS Symptomatic vasospasm occurred in 22.2% surgical patients compared with 17.2% endovascular treatment patients (P=0.37). Multivariate analysis revealed that the probability of occurrence of symptomatic vasospasm decreased with age >50 years (relative risk [RR], 0.47 [0.25 to 0.88]) and severe World Federation of Neurological Surgeons (WFNS) grade measured on admission (RR, 0.43 [0.20 to 0.90]) and increased with hyperglycemia occurring during the intensive care stay (RR, 1.94 [1.04 to 3.63]). No difference in risk of symptomatic vasospasm could be identified between surgical and endovascular treatment. Symptomatic vasospasm (OR, 4.73 [CI, 1. 77 to 12.6]) as well as WFNS grade of >2 (OR, 8.95 [3.46 to 23.2]), treatment complications (OR, 8.39 [3.16 to 22.3]), and secondary brain insults were associated with an increased risk of 6-month sequelae. CONCLUSIONS Age <50 years, good neurological grade, and hyperglycemia were all associated with an increased risk of cerebral vasospasm whereas treatment was not. This provides a basis for future clinical prospective randomized trials comparing both treatments.

Abstract
OBJECTIVE To study the safety and efficacy of endovascular treatment of acutely ruptured aneurysms with Guglielmi detachable coils. METHODS From August 1992 until December 1995, 75 patients were referred for endovascular treatment of acutely ruptured aneurysms. There were 49 women and 26 men, with a mean age of 55 years. Patients were classified according to the Hunt and Hess grading system. There were 18 Grade I patients (24%), 13 Grade II patients (17%), 30 Grade III patients (40%), 11 Grade IV patients (15%), and 3 Grade V patients (4%). Fifty patients (66%) were treated within 48 hours, and 64 (85%) were treated within 1 week of hemorrhage. The most frequently treated aneurysms were located at the basilar bifurcation (32%), anterior communicating artery (16%), posterior communicating artery (15%), and ophthalmic segment of the carotid artery (11%). Most of the aneurysms were smaller than 15 mm (77%). Fifty-six percent of the aneurysms had small (4 mm) necks, and 44% had wide (> 4 mm) necks. Clinical follow-up was performed at 6 months, and results were classified according to the Glasgow Outcome Scale (GOS). Control angiograms were performed immediately, at 6 months, and yearly thereafter. RESULTS Immediate angiographic results were considered to be satisfactory in 58 patients (77%) (complete obliteration, 40%; residual neck and dog ear, 37%). Technical failures occurred in 5 patients (7%), and 12 patients experienced some residual opacification of their aneurysms (16%). The procedure-related mortality and morbidity rate was 8%. At 6 months, the outcomes were as follows: GOS score of 1, 50 patients (66.7%); GOS score of 2, 4 patients (5.3%); GOS score of 3, 4 patients (5.3%); and GOS score of 5, 17 patients (22.7%). The main causes of death and disability at 6 months were the direct effect of the initial hemorrhage (9%), delayed ischemia (6.7%), subsequent bleeding (4%), intraprocedural rupture (4%), open surgical complications (3%), and unrelated deaths (4%). Six-month angiographic follow-up data were available for 50 patients (67%). The morphological results were considered to be satisfactory in 44 of these 50 patients (88%) (complete occlusion, 46%; residual neck or dog ear, 42%). CONCLUSION Endovascular treatment of acutely ruptured aneurysms was attempted without clinically significant complication in 92% of the patients. The morphological results were unsatisfactory in 23% of the patients. Complete obliteration of the sac, with or without residual neck, is essential to prevent subsequent bleeding, which occurred in 5% of the patients. The overall outcome at 6 months was similar to that of surgical series, despite a selected group of patients with negative prognostic factors.

Abstract
Vasospasm following aneurysmal subarachnoid hemorrhage (SAH) is correlated with the thickness of blood within the basal cisterns on the initial computerized tomography (CT) scan. To identify additional risk factors for symptomatic vasospasm, the authors performed a prospective analysis of 75 consecutively admitted patients who were treated for aneurysmal SAH. Five patients who died before treatment or were comatose postoperatively were excluded from the study. Of the remaining 70 patients, demographic (age, gender, and race) and clinical (hypertension, diabetes, coronary artery disease, smoking, alcohol abuse, illicit drug use, sentinel headache, Fisher grade, Hunt and Hess grade, World Federation of Neurological Surgeons grade, and ruptured aneurysm location) parameters were evaluated using multivariate logistic regression to determine factors independently associated with cerebral vasospasm. All patients were treated with hypervolemic therapy and administration of nimodipine as prophylaxis for vasospasm. Cerebral vasospasm was suspected in cases that exhibited (by elevation of transcranial Doppler velocities) neurological deterioration 3 to 14 days after SAH with no other explanation and was confirmed either by clinical improvement in response to induced hypertension or by cerebral angiography. The mean age of the patients was 50 years. Sixty-three percent of the patients were women, 74% were white, 64% were cigarette smokers, and 46% were hypertensive. Ten percent of the patients suffered from alcohol abuse, 19% from sentinel bleed, and 49% had a Fisher Grade 3 SAH. Twenty-nine percent of the patients developed symptomatic vasospasm. Multivariate analysis demonstrated that cigarette smoking (p = 0.033; odds ratio 4.7, 95% confidence interval [CI] 2.4-8.9) and Fisher Grade 3, that is, thick subarachnoid clot (p = 0.008; odds ratio 5.1, 95% CI 2-13.1), were independent predictors of symptomatic vasospasm. The authors make the novel observation that cigarette smoking increases the risk of symptomatic vasospasm after aneurysmal SAH, independent of Fisher grade.

Abstract
Advanced age is a recognized prognostic indicator of poor outcome after subarachnoid hemorrhage (SAH). The relationship of age to other prognostic factors and outcome was evaluated using data from the multicenter randomized trial of nicardipine in SAH conducted in 21 neurosurgical centers in North America. Among the 906 patients who were studied, five different age groups were considered: 40 years or less, 41 to 50, 51 to 60, 61 to 70, and more than 71 years. Twenty-three percent of the individuals enrolled were older than 60 years of age. Women outnumbered men in all age groups. Level of consciousness (p = 0.0002) and World Federation of Neurological Surgeons grade (p = 0.0001) at admission worsened with advancing age. Age was also related to the presence of a thick subarachnoid clot (p = 0.0001), intraventricular hemorrhage (p = 0.0003), and hydrocephalus (p = 0.0001) on an admission computerized tomography scan. The rebleeding rate increased from 4.5% in the youngest age group to 16.4% in patients more than 70 years of age (p = 0.002). As expected, preexisting medical conditions, such as diabetes (p = 0.028), hypertension (p = 0.0001), and pulmonary (p = 0.0084), myocardial (p = 0.0001), and cerebrovascular diseases (p = 0.0001), were positively associated with age. There were no age-related differences in the day of admission following SAH, timing of the surgery and/or location, and size (small vs. large) of the ruptured aneurysm. During the treatment period, the incidence of severe complications (that is, those complications considered life threatening by the reporting investigator) increased with advancing age, occurring in 28%, 33%, 36%, 40%, and 46% of the patients in each advancing age group, respectively (p = 0.0002). No differences were observed in the reported frequency of surgical complications. No age-related differences were found in the overall incidence of angiographic vasospasm; however, symptomatic vasospasm was more frequently reported in the older age groups (p = 0.01). Overall outcome, assessed using the Glasgow Outcome Scale at 3 months post-SAH, was poorer with advancing age (p < 0.001). Multivariate analysis of overall outcome, adjusting for the different prognostic factors, did not remove the age effect, which suggests that the aging brain has a less optimal response to the initial bleeding. Age as a risk factor is a continuum; however, there seems to be a significant increased risk of poor outcome after the age of 60 years.

Abstract
BACKGROUND AND PURPOSE Age may influence cost or effectiveness of treatment for subarachnoid hemorrhage (SAH). This study examined the effect of age on both. METHODS Patients (n = 219) who underwent craniotomy for intracranial aneurysm and SAH over 6 years at one tertiary care center were divided in two ways by age: single advanced age (< 65 years and > or = 65 years) and decade of age (23 to 39, 40 to 49, 50 to 59, 60 to 69, and 70 to 81 years). Data recorded for each patient included numbers of procedures and complications in the surgical intensive care unit (SICU), number of days in the SICU and the hospital, costs for SICU and ward care, total cost (SICU plus ward costs), and the Acute Physiology and Chronic Health Evaluation (APACHE) II score at admission and discharge, the Hunt-Hess grade at admission and immediately preoperatively, and quality of life score, a measure of outcome. Mortality rates by age group were calculated. RESULTS The only variable significantly affected by decade of age was mortality rate, which increased as decade of age increased (3% to 17%). With the 65-year comparison, mortality rate, cost, APACHE II score at admission and discharge, days before operation, and days in the SICU were significantly higher for age > or = 65 years. CONCLUSIONS Whereas mortality is higher for the older age group, quality of life scores appear acceptable for those who survive. Even though the hospital costs of treating elderly patients for SAH may be higher than those for younger patients, this should not be used to justify withholding care from the elderly.

Abstract
The factors contributing to neurological deterioration after early surgery for aneurysmal subarachnoid hemorrhage (SAH) were investigated. One hundred forty-two patients who underwent surgery within 3 days after SAH and recovered consciousness were divided into three age groups: 49 years of age or younger (Group A), 50 to 64 years old (Group B), and 65 years of age or older (Group C). Among these, 40 patients (28%) overall showed neurological deterioration; these cases were analyzed in detail. Although the highest incidence of deterioration was noted in patients in Group C (42%), angiographic vasospasm, quantified by measuring the change in the ratio of the diameters of the intracranial arteries to the extracranial internal carotid artery, was negatively correlated with age. In elderly patients, the severity of angiographic vasospasm was not related to the reversibility of symptoms or the outcome. At the time of aggravation, associated systemic complications such as cardiac decompensation, hypoxia, and electrolyte imbalance were noted in two (18%) of 11 patients in Group A, five (38%) of 13 in Group B, and eight (50%) of 16 in Group C, and these complications were significantly correlated with poor outcome in Group C. Although arterial narrowing is a leading cause of neurological deterioration after early aneurysmal surgery, the etiology is often multifactorial, especially in elderly patients, suggesting that hypervolemic therapy, which might provoke various complications, should be performed carefully under intensive monitoring.

Abstract
BACKGROUND The purpose of this study is to investigate whether rapid spontaneous diminution of cisternal subarachnoid hemorrhage (SAH) alleviates vasospasm in the corresponding arterial territory. METHODS The subjects were 103 patients in whom initial computed tomography scans were performed within 24 hours after SAH and repeated within 72 hours. We analyzed the effect of diminution of cisternal SAH on vasospasm in 16 sites in each patient. Of the total 1642 cisterns. SAH was found in 1362 (83%), of which 539 (40%) had a decrease in SAH. The highest diminution rate was 64% in quadrigeminal cistern, and the lowest rate was 27% in frontal interhemispheric fissure (IHF). In basal frontal IHF, both the incidence of diminution of SAH and its degree were significantly lower in patients with ruptured anterior cerebral artery aneurysms than in those with other site aneurysms, while in suprasellar cisterns, sylvian stems, and sylvian fissures, diminution of SAH was not affected by the side of ruptured aneurysms. The diminution of SAH in basal frontal IHF and sylvian stems was associated with less vasospasm in adjacent arteries. CONCLUSIONS We concluded that in patients with SAH, rapid spontaneous diminution of cisternal blood, which is affected by several factors, makes vasospasm in the corresponding arterial territory less likely.

Abstract
Subsequent to admission after aneurysmal subarachnoid haemorrhage (SAH), 120 patients (74 women and 46 men) underwent microsurgical clipping of a total of 158 cerebral aneurysms within 96 hours after the bleed. Their mean age was 46 (20-91) years. Computed tomography (CT) findings were graded according to the modified Fisher scale and all patients had daily transcranial doppler (TCD) recordings of their basal cerebral arteries. In 19% of SAH was grade I on CT, in 44% grade II and in 37% grade III. The rate of patients who developed severe vasospasm as documented by TCD (mean blood flow velocities exceeding 160 cm/s on 2 or more consecutive days) was 39% for grade I patients, 26% for grade II patients and 34% for patients with SAH grade III on the initial CT. There was no difference in the rate of occurrence of severe vasospasm, when the patients were split into 2 groups according to the time of performance of the initial CT scan-within 24 hours, and 48-80 hours after SAH, respectively. It is concluded that the amount of subarachnoid blood on the initial CT scan should no longer be used as the indicator for occurrence and severity of the multifactorial entity vasospasm.

Abstract
In patients with subarachnoid hemorrhage (SAH), the effect of clot removal on cerebral vasospasm is still in dispute. The purpose of this study is to investigate whether rapid spontaneous diminution of subarachnoid blood alleviates vasospasm. We analyzed the effect of diminution of SAH on vasospasm in 36 patients with SAH grades III-IV who were operated on by the same surgeon by day 6 after SAH. The diminution of subarachnoid blood became more apparent with shorter interval between hemorrhage and initial computed tomography (CT) scan, with increasing patient age, and with higher SAH grades. The incidences of angiographic vasospasm grades III-IV, permanent symptomatic vasospasm, and low-density area on CT scans decreased with the increase in the degree of diminution of subarachnoid blood. Permanent symptomatic vasospasm and low-density area on CT scans were found in 5 of 9 patients with no diminution, whereas they occurred only in 5 of 27 patients with diminution (p < .05). We concluded that spontaneous diminution of subarachnoid blood in the acute stage after SAH seems to reduce the severity of vasospasm.

Abstract
Intracranial aneurysm surgery performed between 4 and 12 days after subarachnoid hemorrhage (SAH) has been associated with an increased risk of delayed cerebral ischemia and poor outcome compared to surgery performed before or after this time. To investigate whether this increased risk is due to aggravation of vasospasm, the angiograms obtained before and after surgery in 56 patients operated on at various times after aneurysmal SAH were studied. Vasospasm was quantitated by measuring the diameters of intracranial arteries and expressed as the ratio of the diameters of the intracranial arteries to the diameter of the extracranial internal carotid artery. Aggressive surgical clot removal was not performed at surgery. To correct for differences in prognostic factors for vasospasm between patients operated on at different times after SAH, multiple regression analysis was performed using the arterial diameter ratio during vasospasm as the dependent variable and the prognostic factors for vasospasm, including the time of surgery, as independent variables. Equations predicting the severity of vasospasm could be generated using the clinical grade on admission, patient age, and preoperative arterial diameter ratio. The time of surgery had no effect on vasospasm. Cerebral infarction due to vasospasm developed in five (15%) of 34 patients operated on within 3 days after SAH and in four (20%) of 20 operated on between 4 and 12 days after SAH (p = 0.66). A good outcome for these two groups was achieved in 88% and 85%, respectively (p = 1.00). These results suggest that the timing of surgery does not affect the development of vasospasm. Any increased risk of cerebral ischemia associated with surgery performed between 4 and 12 days after SAH is due to factors other than aggravation of vasospasm.

Abstract
The purpose of this study was to investigate whether the overall management outcome for elderly patients with subarachnoid hemorrhage (SAH), especially for those aged 70 to 79 years, has improved. To this end, the author compared data for the period between 1986 and 1990 (Study Period 2) with those obtained between 1980 and 1985 (Study Period 1). Of 503 patients who were admitted by Day 3 after SAH during the two study periods, 243 (48%) were 59 years of age or younger, 129 (26%) were 60 to 69 years of age, 102 (20%) were 70 to 79 years of age, and 29 (6%) were 80 years of age or older. The percentage of patients aged 70 years or more doubled from 17% during Study Period 1 to 34% during Study Period 2. During Study Period 1, the older patients had a lower operability rate; during Study Period 2, the operability rate for patients aged 70 to 79 years (69%) was similar to that for patients aged 50 to 69 years. At 6 months after SAH for patients aged 70 to 79 years, the overall management and surgical results of good recovery or moderate disability were 18% and 36%, respectively, during Study Period 1, and improved to 41% and 60%, respectively, during Study Period 2. During Study Period 1, the cumulative 5-year survival probabilities for overall management were 58% for patients aged 59 years or less, 53% for those aged 60 to 69 years, and 24% for those aged 70 to 79 years; during Study Period 2, these probabilities improved to 70%, 58%, and 47%, respectively. The 5-year survival rates of surgically treated patients in these three age groups increased from 77%, 68%, and 44% to 88%, 77%, and 69%, respectively.
