Eur J Neurol 2021; 28:3012-3021. [PMID: 34192398 DOI: 10.1111/ene.15002] [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: 06/14/2021] [Accepted: 06/27/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND AND PURPOSE To determine the long-term survival outcomes of and prognostic factors for survival in patients with a ruptured intracranial aneurysm (RIA) who underwent endovascular coil embolization or surgical clipping. METHODS We selected patients who had received a diagnosis of RIA between January 1, 2011 and December 31, 2017. Propensity score matching was performed, and Cox proportional hazards model curves were plotted to analyze all-cause mortality in patients undergoing different treatments. RESULTS The matching process yielded a final cohort of 8102 patients (4051 and 4051 in endovascular coil embolization and surgical clipping groups, respectively) who were eligible for inclusion. In multivariate Cox regression analyses, the adjusted hazard ratio (aHR) and 95% confidence interval (CI) for endovascular coil embolization compared with surgical clipping were 0.87 (95% CI, 0.79-0.97). The aHRs for the ages of 65 to 74, 75 to 84, and ≥85 years compared with the ages of 20 to 64 years were 1.82 (95% CI, 1.60-2.07), 3.35 (95% CI, 2.93-3.84), and 6.99 (95% CI, 5.51-8.86), respectively. Surgical clipping; old age; male sex; treatment during 2011 to 2013; presence of diabetes, congestive heart failure, hypertension, chronic kidney disease, or end-stage renal disease; history of stroke or transient ischemic attack; Charlson Comorbidity Index ≥2; attendance of nonacademic hospitals; and low income were significant independent prognostic factors for poor survival. CONCLUSIONS Compared with surgical clipping, endovascular coil embolization led to more favorable survival outcomes in patients with RIAs.

Abstract
Objective As the average life span in modern society continues to increase, much interest is focused on high-risk procedures in elderly patients, including major surgical operations. We investigated the results of endovascular coiling of unruptured intracranial aneurysms (UIA) in patients over 80 years of age. Methods We retrospectively analyzed 39 patients aged over 80 years who underwent coil embolization for UIA between April 2007 and April 2019 at our hospital. Results Complete occlusion on digital subtraction angiography (DSA) immediately after surgery was performed in 44 (84.6%) of 52 cases of cerebral aneurysms. Four patients (7.7%) had residual aneurysmal necks, and four (7.7%) had contrast flow in the aneurysmal sac. Follow-up magnetic resonance angiography (mean: 8.2 months) was performed in 37 aneurysms in 24 patients. There was evidence of blood flow in the neck in seven cases (18.9%) and aneurysm in two cases (5.4%). Follow-up DSA (mean: 20.5 months) was performed in 14 aneurysms in 11 patients, and 11 aneurysms (78.6%) had complete occlusion, 1 aneurysm (7.1%) had an aneurysmal neck, and 2 aneurysms (14.3%) had contrast filling into the aneurysmal sac. Coil embolization procedure-related complications occurred in 3 patients (7.7%). Cerebral infarction occurred in 1 (2.6%), arterial dissection in 1 (2.6%), and hypoesthesia in 1 (2.6%). Conclusions Active treatment of UIA in elderly patients over 80 years of age through endovascular coil embolization can be considered.

Abstract
ABSTRACT We retrospectively evaluated the records of 49 grade 4 and 5 patients with 42 intracranial aneurysms treated within 72 h of subarachnoid hemorrhage (SAH). In total, 35 patients (71%) were grade 4, and 14 (29%) were grade 5. A total of 42 (85%) patients had one aneurysm, 6 (12%) had two aneurysms, and 1 (3%) had three aneurysms. Out of 49 patients, one technical (2%) and one clinical (2%) complication occurred at surgery. Twenty-one (43%) patients recovered well, including 7 with postoperative hematoma requiring an immediate evacuation of a clot. Fourteen (29%) patients had hydrocephalus and required a ventriculo-peritoneal shunt; 12 patients underwent tracheotomy postoperatively due to coma and pulmonary infection. We found that patients with Hunt and Hess grade 4 and 5 aneurysms can undergo successful neurosurgical clipping of the aneurysms after SAH. However, the morbidity and mortality rates remain high because of their poor clinical condition and a high incidence of vasospasm during treatment.

Prognosis Predicting Score for Endovascular Treatment of Aneurysmal Subarachnoid Hemorrhage: A Risk Modeling Study for Individual Elderly Patients. Medicine (Baltimore) 2016; 95:e2686. [PMID: 26886607 PMCID: PMC4998607 DOI: 10.1097/md.0000000000002686] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2015] [Revised: 10/09/2015] [Accepted: 01/11/2016] [Indexed: 11/30/2022] Open
Abstract
The elderly patients with aneurysmal subarachnoid hemorrhage (aSAH) have a greater risk of poor clinical outcome after endovascular treatment (EVT) than younger patients do. Hence, it is necessary to explore which factors are associated with poor outcome and develop a predictive score specifically for elderly patients with aSAH receiving EVT. The aim of this study was to develop and validate a predictive score for 1-year outcomes in individual elderly patients with aSAH underwent EVT.In this 10-year prospective study, 520 consecutive aSAH elderly (age ≥ 60 years) patients underwent EVT in a single center were included. The risk factors, periprocedural, and 1-year follow-up data of all patients were entered in a specific prospective database. The modified Rankin scale was used for evaluating clinical outcome. To optimize the model's predictive capacity, the original matrix was randomly divided in 2 submatrices (learning and testing). The predictive score was developed using Arabic numerals for all variables based on the variable coefficients (β) of multivariable logistic regression analysis in the learning set and the predictive performance evaluation was assessed in the testing set. The risk classes were constructed using classification criteria based on sensitivity and specificity. The poor outcome rate at 1 year was 26.15%. Six risk factors, including age, hypertension, Hunt-Hess scale, Fisher scale, aneurysm location, and periprocedural complications, were independently associated with poor outcome and assembled the Changhai score. The discriminative power analysis with the area under the receiver operating characteristic curve (AUC) of the Changhai score was statistically significant (0.864, 0.824-0.904, P < 0.001). The sensitivity and specificity of the Changhai score were 82.07% and 78.06%, respectively. Our study indicated that age, hypertension, Hunt-Hess scale, Fisher scale, aneurysm location, and periprocedural complications were independent risk factors of poor outcome for elderly aSAH patients underwent EVT. In combination with these risk factors, the Changhai score can be a useful tool in the prediction of clinical outcome but needs to be validated in various centers before it can be recommended for application.

Abstract
OBJECT The pathophysiology of aneurysmal subarachnoid hemorrhage (aSAH) is unclear. Sex may play a role in the outcome of patients with aSAH. METHODS The authors retrospectively identified 617 patients with aSAH (April 2005 to February 2010) and analyzed sex differences in risk factors (age, hypertension, smoking, alcohol consumption, and family history), admission-related factors (World Federation of Neurosurgical Societies grade and admission delay), aneurysm characteristics (site, side, location, and multiplicity), and outcomes (treatment modalities [coiling/clipping/both/conservative], complications [vasospasm and hydrocephalus], length of stay, and modified Rankin Scale score at 3 months). RESULTS The female patients with aSAH were older than the male patients (mean age 56.6 vs 51.9 years, respectively, p < 0.001), and more women than men were ≥ 55 years old (56.2% vs 40.4%, respectively, p < 0.001). Women exhibited higher rates of bilateral (6.8% vs 2.6%, respectively, p < 0.05), multiple (11.5% vs 5.2%, respectively, p < 0.05), and internal carotid artery (ICA) (36.9% vs 17.5%, respectively, p < 0.001) aneurysms and a lower rate of anterior cerebral artery aneurysms (26.3% vs 44.8%, respectively, p < 0.001) than the men, but no side differences were noted. There were no sex differences in risk factors, admission-related factors, or outcome measures. For both sexes, outcomes varied according to aneurysm location, with odds ratios for a poor outcome of 1.62 (95% CI 0.91-2.86, p = 0.1) for middle cerebral artery, 2.41 (95% CI 1.29-4.51, p = 0.01) for ICA, and 2.41 (95% CI 1.29-4.51, p = 0.006) for posterior circulation aneurysms compared with those for anterior cerebral artery aneurysms. The odds ratio for poor outcome (modified Rankin Scale score of 4-6) in women compared with men after adjusting for significant prognostic factors was 0.71 (95% CI 0.45-1.11, p > 0.05). CONCLUSIONS The overall outcomes after aSAH between women and men are similar.

Abstract
Objective The aim of this study was to compare clinical characteristics of ruptured aneurysms in young adults, of the third and fourth decades of life, and to compare several clinical characteristics affecting the outcome of patients. Methods We retrospectively investigated 1459 patients who underwent surgery and endovascular treatment for ruptured cerebral aneurysms from June 1992 to December 2010 and compared clinical characteristics. We also reviewed pre-existing medical conditions and perioperative complications. Results Among 1459 patients, there were 21 patients (1.44%) in the third decade and 104 patients (7.13%) in the fourth decade of life. Within two age groups, 88 (70.4%) were male and 37 (29.6%) were female, a ratio of 2.37 : 1. In both groups, we observed the anterior cerebral artery (ACA) aneurysm with the most frequency (p=0.028). In general, favorable outcome was achieved in both age groups (90.5% and 81.7%, respectively). An initial univariate analysis showed Hunt-Hess grade, Fisher grade, location of aneurysm, and rebleeding significantly associated with outcome after aneurysm rupture. Further, multivariate analysis demonstrated that only Hunt-Hess grade (grade 4-5) was a risk factor for the outcome (odds ratio=9.730, 95% confidence interval 2.069-45.756, p=0.004). Conclusion The incidence of subarachnoid hemorrhage (SAH) was higher in the male population of the third and fourth decades of life. Aneurysms on the ACA were most frequently occurred in both age groups and the outcome of aneurysmal SAH among the third and fourth decades was favorable. Multivariate analysis revealed that high Hunt-Hess grade was a risk factor for patient's outcome.

Abstract
BACKGROUND AND PURPOSE The optimal management of patients with unruptured intracranial aneurysms remains controversial in elderly populations. The aim of this study was to evaluate technical results and clinical outcomes in a single center of consecutive elderly patients with unruptured intracranial aneurysms treated with endovascular embolization. MATERIALS AND METHODS Between May 2003 and February 2010, 96 patients older than 70 years (men, 16 patients; women, 80 patients; mean age, 73 years) with 122 saccular unruptured intracranial aneurysms were treated in our hospital with an endovascular approach. The endovascular procedures and technique, angiographic follow-up, and complications were evaluated. RESULTS Successful embolizations without complications were completed in 95.9%. Five patients had procedure-related events, including thromboembolism in 1 patient, aneurysm perforation during the procedure in 1, and 3 postoperative transient minor symptoms (headache, otalgia, and trigeminal pain) in 3. The degree of occlusion of the treated aneurysm was complete in 46.7%; there was a small neck remnant in 40.9% and residual filling in 12.2%. Imaging (MR angiography) follow-up was performed in 68.7% of the patients. The mean follow-up duration was 19.4 months (range, 5-57 months). Fifty-five patients (93.9%) showed no interval change of the residual neck. Four (6%) demonstrated recanalizations, all of which were successfully recoiled. CONCLUSIONS Endovascular treatment of unruptured intracranial aneurysms in patients older than 70 years of age appears to be safe. Favorable outcomes with low morbidities may replace surgery or conservative treatment as an active management alternative.

Abstract
BACKGROUND AND PURPOSE It is often thought that elderly patients in particular would benefit from endovascular aneurysm treatment. The aim of this analysis was therefore to compare the efficacy and safety of endovascular coiling (EVT) with neurosurgical clipping (NST) in the subgroup of elderly SAH patients in the International Subarachnoid Aneurysm Trial (ISAT). METHODS In the ISAT cohort 278 SAH patients, 65 years or older, were enrolled. The patients were randomly allocated EVT (n=138) or NST (n=140). The primary outcome was the proportion of patients with a modified Rankin scale score of 0 to 2 (independent survival) at 1 year after the SAH. The rates of procedural complications and adverse events were also recorded. RESULTS 83 of 138 (60.1%) patients allocated EVT were independent compared to 78 of 140 (56.1%) allocated NST (N.S.). 36 of 50 (72.0%) patients with internal carotid and posterior communicating artery aneurysms allocated EVT were independent compared to 26 of 50 (52.0%) allocated NST (P<0.05). 10 of 22 (45.5%) patients with middle cerebral artery aneurysms allocated EVT were independent compared to 13 of 15 (86.7%) allocated NST (P<0.05). The epilepsy frequency was 0.7% in the EVT group compared to 12.9% in the NST group (P<0.001). CONCLUSIONS In good grade elderly SAH patients with small anterior circulation aneurysms, EVT should probably be the favored treatment for ruptured internal carotid and posterior communicating artery aneurysms, whereas elderly patients with ruptured middle cerebral artery aneurysms appear to benefit from NST. EVT resulted in a lower epilepsy frequency than NST.

Abstract
Aneurysmal subarachnoid hemorrhage is uncommon in young adults. The aim of this study was to compare clinical characteristics of ruptured aneurysms between males and females in the third or fourth decade of life. We retrospectively investigated 301 patients who underwent surgery for ruptured cerebral aneurysms over 6 years. Among them, 53 patients were aged between 20-39 years. Clinical characteristics and related variables were compared between genders. In general, there was a favorable outcome in either gender (84.9%). There was a higher incidence of multiplicity and intraoperative rupture in females, as well as a significant difference in aneurysm location between genders (p=0.030, p=0.014, and p=0.027 respectively). Overall outcome was not different between the two groups. These results suggest that aneurysm formation may differ between genders.

Abstract
We report our experience in the endovascular treatment with detachable platinum coils of ruptured or symptomatic unruptured cerebral aneurysms in 61 patients aged 70-82 years. Complete occlusion was achieved in 38, subtotal in 17 and partial in one. The treatment failed in five patients. Clinical follow-up was performed in all patients for 8 months to 8 years. No bleeding occurred during the follow-up period. Outcome was favourable in 63% of the patients. When we compared the outcome of elderly patients with those of younger age endovascularly treated in the same period of time, we found a significantly higher frequency of poorer outcome in the elderly group (chi(2) = 9.084; P = 0.011). The frequency of favourable outcome in the elderly was significantly lower than in the younger group for H-H IV-V (chi(2) = 9.299; P = 0.010). The most important factor influencing the outcome was not age itself, but primary clinical condition on admission. The therapy of symptomatic aneurysms in elderly patients should not be purely conservative--a direct approach of the aneurysm should be considered. Endovascular treatment whenever possible seems to be a good alternative to surgery.

Abstract
ABSTRACT
OBJECTIVE:
We report on the consequences of introducing coil embolization for the total management of and outcome in patients with subarachnoid hemorrhage (SAH).
METHODS:
In southern Sweden, a prospective analysis of all patients with SAH of verified aneurysmal origin was conducted during the 3 years when coiling was gradually being introduced. The incidence of acute or chronic hydrocephalus, vasospasm, delayed ischemic deterioration, and outcome at 3 to 6 months after bleeding was analyzed.
RESULTS:
Coiling of aneurysms was used progressively more compared with clipping during the study period. The number of patients subjected to coiling was 26 (36%) of 73 patients during calendar year 1997, 43 (53%) of 81 patients in 1999, and 55 (74%) of 74 patients in 2001 (P < 0.0001). Gradually, more elderly patients were admitted during the study period. Virtually all aneurysms located in the posterior circulation were treated by coil embolization, even at the start of the study, whereas aneurysms at all other locations were progressively more likely to be treated similarly. The incidence of hydrocephalus in the acute (average for all 3 yr, 39%) or chronic (16%) phase, vasospasm as measured by Doppler sonography (33%), and delayed ischemic deterioration (29%), as well as outcome at 3 to 6 months (61% good recovery, 13% deceased), did not change significantly during the study. The main cause of unfavorable outcome was the severity of the SAH.
CONCLUSION:
The increasing use of coil embolization for ruptured aneurysms in the anterior circulation did not have any significant impact on the overall incidence of SAH-related complications or outcome. The main determinant for outcome after SAH is still the severity of the SAH.

OBJECT The goal in this study was to develop an interactive, probabilistic decision-analysis system for clinical use in the decision to treat or observe unruptured intracranial aneurysms. Further goals were to enable users of the system to adapt decision-analysis methods to individual patients and to provide a tool for interactive sensitivity analysis. METHODS A computer program was designed to model the outcomes of treatment and observation of unruptured aneurysms. The user supplies probabilistic estimates of key parameters relating to a specific patient and nominates discount rate and quality of life adjustments. The program uses Monte Carlo discrete-event simulation methods to derive probability estimates of the outcomes of treatment and observation. Results are expressed as summary statistics and graphs. Discounted quality-adjusted life years are graphed using survival methods. Hierarchical simulations are used to enable investigators to perform probabilistic sensitivity analysis for one or multiple parameters simultaneously. The results of sensitivity analysis are expressed in graphs and as the expected value of perfect information. The system can be distributed and updated using the Internet. CONCLUSIONS Further research is required into the benefits of clinical application of this system. Further research is also required into the optimum level of complexity of the model, into the user interface, and into how clinicians and patients are likely to interpret results. The system is easily adaptable to a range of medical decision analyses.

Abstract
OBJECT The authors reviewed the management protocols for young adults who presented with subarachnoid hemorrhage (SAH) at the Regional Neurosurgery Unit in Newcastle during a study period of 9 years. Aneurysmal SAH is uncommon in the age group selected (18-39 years) and, therefore, the performance of these patients has not been extensively reported in the literature. The authors also evaluated the good-grade rebleed rate (an index of management efficiency) in this cohort of patients. METHODS The Newcastle neurosurgical unit serves a population of close to 3 million people, and an average of 180 patients with SAH are seen each year. The majority of patients are transferred from other hospitals in the region. This study includes patients admitted between January 1990 and December 1998. A total of 1,609 patients were admitted during this period, of whom 295 (18.4%) between the ages of 18 and 39 years constituted the study population of young adults. Two hundred ninety-five young adults presented with SAH; 181 (61.4%) were women and 114 (38.6%) were men, a ratio of 3:2. Of 246 patients in whom this value was recorded, 15 (6.1%) presented with a history of hypertension, and there was an association between hypertension and the occurrence of multiple aneurysms (Fisher two-tailed exact test, p = 0.008). Thirty-five patients (11.9%) presented with a hematoma on computerized tomography scans; of these, 20 (57%) were women and 15 were men. In six patients the lesion had rebled before treatment. The good-grade rebleed rate was three (1.7%) of 178. The overall favorable outcome rate was 83.8% (Glasgow Outcome Scale [GOS] 4 and 5) and unfavorable outcome occurred in 16.2% (GOS 1-3), with a total of 40 deaths in this group (13%). Age had no influence on outcome in young adults. Comparing the outcome at discharge with the follow-up evaluation at 6 months revealed that patients in the moderate and severe disability groups continued to improve and many achieved good recovery. CONCLUSIONS In this report the authors detail the outcome of a large number of young adults with SAH. The incidence of SAH was higher in the female population, although the ratio was not as high as previously reported. The authors have also demonstrated a progressive increase in the incidence of aneurysmal SAH with age, even in young adults. Hypertension but not age influenced the occurrence of multiple aneurysms. The good-grade rebleed rate is low, although it is not zero. Generally, a satisfactory outcome was obtained and significant continuing improvements were noted between discharge and follow-up evaluation. This reflects the power of recovery in young adults. These are people whose economic productivity and fertility are at peak levels and therefore the financial and social burden occasioned by less-than-perfect outcomes is large.

Abstract
The number of elderly patients admitted with diagnosis of cerebral aneurysms is markedly increasing worldwide. Treatment in this group of patients is certainly more difficult than in the young subjects and not many reports deal with their management. Many factors must be considered deciding if to pursue treatment. Patients admitted after bleeding (subarachnoid haemorrhage, SAH) have a different prognosis from young subjects and those harboring unruptured vascular malformations. We have analyzed the literature on the basis of this distinction.

Abstract
Elderly patients are a growing population group in developing countries because of optimal health care. 13% of Cuba population is older than sixty years and it is expected to grow to 20% in 2005. Subarachnoid hemorrhage secondary to ruptured aneurysms in geriatric patients carries a high mortality but a few patients are selected for surgical treatment. Manuel Ascunce Domenech Hospital attended 1112 patients older than 60 years between January 1994 and December 2001. Of these there were 96 patients with symptomatic intracranial aneurysms and we selected 30 for surgical treatment. They were all in clinical grades I and II of the WFNS scale. They had good health to face surgery and familiar consent. The size and location of the aneurysms were not considered among the exclusion criteria. Aneurysms were mainly localized at posterior communicating and middle cerebral arteries. There were two deaths, one due to a medical cause an the other to the surgical procedure. 74% of the patients obtained satisfactory outcome six month after the operation. The clue is to not consider age as a negative point for surgery. Surgical procedures can be performed in patients with good clinical grade (WFNS). New technical advances, stroke units, accurately selected patients and minimal invasive surgical methods will help to obtain good results.

Abstract
BACKGROUND AND PURPOSE The elderly constitute a significant and increasing proportion of the population. The aim of this investigation was to study time trends in clinical management and outcome in elderly patients with subarachnoid hemorrhage. METHODS Two hundred eighty-one patients >/=65 years of age with aneurysmal subarachnoid hemorrhage who were accepted for treatment at the Uppsala University Hospital neurosurgery clinic during 1981 to 1998 were included. Hunt and Hess grades on admission, specific management components, and clinical outcomes were recorded. Three periods were compared: A, 1981 to 1986 (before neurointensive care); B, 1987 to 1992; and C, 1993 to 1998. RESULTS The volume of elderly patients (>/=65 years of age) increased with time, especially patients >/=70 years of age. Furthermore the proportion of patients with more severe clinical conditions increased. A greater proportion of patients had a favorable outcome (A, 45%; B, 61%; C, 58%) despite older ages and more severe neurological and clinical conditions. In period C, Hunt and Hess I to II patients had a favorable outcome in 85% of cases compared with 64% in period A. This was achieved without any increase in the number of severely disabled patients. CONCLUSIONS Elderly patients with subarachnoid hemorrhage can be treated successfully, and results are still improving. The introduction of neurointensive care may have contributed to the improved outcome without increasing the proportion of severely disabled patients. A defeatist attitude toward elderly patients with this otherwise devastating disease is not justified.

Abstract
Spontaneous subarachnoid haemorrhage (SAH) due to ruptured saccular aneurysm is the fourth most frequent cerebrovascular disorder following atherosclerosis, embolism, and primary intracerebral haemorrhage (1). SAH is a common and often devastating condition, which is a significant cause of world-wide morbidity and mortality (2). The aim of this article is to review the epidemiology, pathophysiology and current management of SAH.

Abstract
OBJECT The goal of this study was to investigate the impact of the introduction of the Guglielmi detachable coil (GDC) therapeutic option on the overall management outcome of intracranial aneurysms. The authors accomplished this by assessing patient morbidity and mortality, inflation-adjusted hospital charges, lengths of stay in the hospital and the intensive care unit (ICU), and treatment efficacy. METHODS The authors conducted a retrospective analysis of consecutive cases of intracranial intradural aneurysms managed by a single multidisciplinary neurovascular team at a tertiary care, academic referral center during the 24 months preceding the introduction of the GDC procedure (Group I or pre-GDC era, 77 patients) and during the first 24 months after its introduction (Group II or GDC era, 99 patients). Treatment with GDCs was considered for cases of higher clinical grade or poor surgical risk, or in response to patient preference (27 [27%] of 99 patients in Group II). Host and lesion parameters in our cohort were validated against outcome parameters by using univariate and multivariate analyses. The pre-GDC and GDC subgroups of patients were comparable for major disease severity parameters (patient age, lesion location, clinical grade, and hemorrhage severity). There was no significant difference in clinical outcome at 6 months, infarcts on computerized tomography scanning, or aneurysm obliteration rates before and after introduction of GDC treatment. Decreasing trends in duration of hospital and ICU stay and in inflation-adjusted hospital charges occurred well before and thus were unrelated to the introduction of the GDC therapeutic option. CONCLUSIONS The results of this study do not demonstrate any significant impact of integration of the GDC modality on clinical outcome, mortality, morbidity, or effectiveness of treatment. Ongoing improvements in hospital charges and length of hospital stay appeared unrelated to the introduction of the GDC option.

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 AND PURPOSE The number of elderly people is markedly increasing in Japan. We have investigated the epidemiology and management outcome of cerebral aneurysms in elderly patients aged > or = 70 years. METHODS A total of 3100 patients were enrolled in the Yamaguchi Data Bank of Cerebral Aneurysm between 1985 and 1995. Of these, 598 with ruptured cerebral aneurysms and 120 with unruptured cerebral aneurysms were elderly (ie, aged > or = 70 years). RESULTS The number of elderly patients with cerebral aneurysms has markedly increased since 1991, and in 1995 approximately 30% of all patients with cerebral aneurysms were elderly. In cases of ruptured cerebral aneurysms, the proportion of patients with severe neurological grade did not change and that with an unfavourable outcome did not decrease throughout the 11 years. The proportion of patients with severe neurological grade in the elderly group was higher than in the younger group (< 70 years), and the management outcome of elderly patients for each neurological grade on admission was worse than that of younger patients (P < .01). However, the incidence rate of symptomatic cerebral vasospasm and rebleeding was the same for the two age groups. Eventually, 60.4% of all elderly patients with ruptured cerebral aneurysms had an unfavorable outcome. In cases of unruptured cerebral aneurysms, 63.3% of the selected elderly patients were surgically treated, and the surgical morbidity and mortality rates were 26.3% and 4.0%, respectively. These rates were nonsignificantly higher than those for younger patients. CONCLUSIONS The number of elderly patients with cerebral aneurysms has markedly increased in Yamaguchi. Because of the unsatisfactory management outcome of ruptured cerebral aneurysms and surgical outcome of unruptured cerebral aneurysms in elderly patients during the 11-year period, we propose the treatment of unruptured cerebral aneurysms at a younger age and the use of a screening system to detect these subjects.

Abstract
Before nimodipine was introduced as a standard treatment in patients with aneurysmal subarachnoid haemorrhage (SAH) females had a significantly poorer outcome which might be due to a higher frequency of delayed cerebral ischaemia (DCI). We evaluated the overall outcome with regard to gender in 188 consecutive patients with a verified ruptured intracranial aneurysm treated with nimodipine. The only significant differences concerning prognostic factors between the sexes were a higher frequency of SAH at the primary CT in female (p < 0.05) and a higher frequency of middle cerebral artery aneurysms in females (p < 0.01). These factors affect the outcome in females unfavourably. However, contrary to previous studies, we found no difference in overall outcome after three months between the sexes in this clinical material. Our observation can be explained by a positive effect of nimodipine on DCI.

Abstract
To determine the relationship between clinical grade on admission and treatment cost after aneurysm rupture, the authors retrospectively examined the length of hospital stay (LOS) and total hospitalization costs (excluding professional fees) for 543 patients admitted for aneurysm surgery between 1983 and 1993. The overall median LOS was 18 days, with a range of 1 to 165 days. Increased median LOS correlated with Hunt and Hess Grades 0 to IV on admission (p < 0.001). Median LOS for Grade V patients was reduced, in part, because of early mortality. Increased treatment cost also correlated with worse admission clinical grade (p < 0.001). A significant proportion of total expenditures occurred early in the hospitalization for patients in all clinical grades. Identification of additional factors affecting the cost of aneurysm treatment is indicated to complement treatment outcome studies.

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
Thirteen percent of Sweden's population (8.6 million) is aged 70 years or older, and this percentage is expected to increase over the coming decades. We have traced every diagnosed case of subarachnoid hemorrhage in patients older than 70 years in a well-defined catchment population of 953,000 individuals. The age-specific incidence for this group was 16 per 100,000 individuals per year, corresponding to 2.3 per 100,000 inhabitants per year. In most recent population-based surgical series on ruptured aneurysms, few patients in this age group are included, corresponding to only 20 to 25% of the actual number of patients, as shown in this study. Surgery is, in many cases, refused to the "elderly" because of age. However, patients who are neurologically intact after the bleed and who are without severe intercurrent diseases are potential candidates for surgical treatment. In our series, surgery yielded good results in two-thirds of 76 patients aged 70 to 74 years who returned to independent living in good mental condition. Among matched patients being refused surgery because of age, 75% suffered morbidity and mortality, with more than half of the patients having died within the 1st 3 months. When calculated for the entire population of Sweden, our data show that a 14% increase in the number of individuals achieving complete remedy from aneurysm rupture each year can be expected with more active therapy among the elderly. Most of these patients are between 70 and 74 years old. In the 9th decade of life, aneurysm surgery probably best remains an exception.

Abstract
In a prospective study of 1076 consecutive patients with aneurysmal subarachnoid haemorrhage (SAH), CT was carried out in 815 patients. CT visible intracerebral haematoma (ICH) was found in 42.6% of the 815 patients. There were no differences in age, pre-existing hypertension or sex between patients with or without ICH. Patients with ICH were in poorer clinical condition on admission, and had a poorer mental outcome and a higher mortality at the 2-year follow-up examination compared with patients without ICH. Of the 491 operated patients, there were in every group according to the clinical condition on admission fewer patients with a normal mental outcome and more fatal cases if an ICH was present after aneurysm rupture. This indicates that the acute brain dysfunction from SAH complicated by ICH is more likely to be followed by permanent cerebral damage compared to the corresponding acute cerebral dysfunction from SAH without ICH.

Abstract
In a prospective consecutive non-randomised study including 1076 patients with ruptured intracranial aneurysms 205 patients received epsilon aminocraproic acid (EACA) and 871 did not. No significant differences between the two groups concerning clinical condition on admission, sex, age, localisation and size of the aneurysms were seen. No cases of rebleeding (RB) were observed within the first 4 days in the EACA treated patients, but within the first 48 hours, which is the optimal period recommended for operation of patients in good clinical condition, this difference of the rates of RB between EACA treated and not treated patients is not significant. A significantly lower rate of RB was observed in the EACA group within the first 2 weeks, but no significant differences in morbidity and mortality were found at the 2-year follow-up examination.
