BACKGROUND AND PURPOSE: The most common cause of poor treatment outcome in patients suffering aneurysmal subarachnoid hemorrhage is cerebral vasospasm, especially in cases of poor Hunt and Hess grades (IV and V). A further prognostic factor in surgically treated patients is aneurysm localization. The aim of the present retrospective study is to compare the endovascular treatment outcome in such poor-grade patients according to aneurysm localization in either the anterior (AC) or posterior (PC) circulation. METHODS: Forty poor-grade patients admitted between 1993 and July 1998 were treated by endovascular approach within 23 days after aneurysm rupture. Eighteen had aneurysms in the AC, 22 in the PC. Mean treatment delay was 4 days after rupture and median, 2 days. One patient showed multiple aneurysms. In 36 cases, aneurysms were occluded by Guglielmi detachable coils; in 4 cases, by parent vessel balloon occlusion. RESULTS: The incidence of delayed ischemic neurological dysfunction or cerebral infarct due to vasospasm did not differ significantly between the AC and PC groups. Two procedure-related complications with clinical effect were observed in each group. At 6 months' follow-up, the result was good in 5 patients and poor in 13 in the AC group and good in 11 patients and poor in 11 in the PC group. CONCLUSION: Given comparable incidence of vasospasm in poor-grade patients, a tendency toward better treatment outcome was found in patients with aneurysms in the posterior circulation (chi(2)=2.04; P=0.15) than in the anterior circulation. Endovascular therapy for poor-grade patients is recommended, as are further studies to determine treatment differences. 相似文献

AbstractSince 7990, early surgery within 3 days following subarachnoid hemorrhage has been performed routinely in our hospital even for ruptured posterior circulation aneurysms. Our experience with early surgical management of 25 patients with posterior circulation aneurysms, including two patients who underwent endovascular surgery, is reported. Fourteen patients had an aneurysm on the basilar, the posterior cerebral or superior cerebellar artery (BAJ, and 77 patients had an aneurysm on the vertebral or posterior inferior cerebellar artery (VA). The mortality and morbidity of the BA group were 7% and 29%, respectively, and those of the VA group were 27% and 9%, respectively. In BA, the incidence ofsymptomatic vasospasm and hydrocephalus was definitely high compared with VA, and the outcome in elderly patients was significantly unfavorable. Early surgery for posterior circulation aneurysms to prevent rebleeding might be considered in selected cases. [Neural Res 1997; 19: 385-388] 相似文献

We evaluated the results of intracranial operation in 150 consecutive patients surgically treated within seven calendar days of aneurysmal subarachnoid hemorrhage (SAH). Patients in all clinical grades, except those who were moribund, were treated. Those with either anterior or posterior circulation aneurysms were included. On follow-up assessment, favorable outcomes were noted in 107 patients (71%), 17 had major disabilities (11%), and 26 had died (17%). During hospitalization, vasospasm was diagnosed in 63 patients (42%) and rebleeding occurred in 39 (25%). Operations were performed throughout the first week after SAH; results of operation were similar on each day. A lower rate of good recovery was observed among patients operatively treated four to seven days after SAH than among those operated on earlier. The admitting neurologic condition influenced outcome after early operation, but age did not have a major impact. We find that aneurysm surgery can be performed within one week of SAH with acceptable results, although there is room for improvement. 相似文献

Antifibrinolytic drugs reduce the risk of rebleeding during the first 2 weeks after aneurysmal subarachnoid hemorrhage. However, they do not lower overall mortality, largely because of an increased incidence of cerebral ischemia. The usefulness of antifibrinolytic drugs might be increased if a method to prevent or control vasospasm in patients were to be developed. We recently completed late Phase I and Phase II studies of the calcium ion blocking drug nicardipine in 67 patients treated within 1 week of subarachnoid hemorrhage. Of these 67 patients, 42 had delayed operations and were treated concomitantly with the antifibrinolytic drug aminocaproic acid (1.5 g/hr) for an average of 6 days before surgery. The outcome of these 42 patients is the subject of this report. Fifteen of 42 patients were treated with the lower dosage levels of nicardipine (0.4-4.5 mg/m2/hr), and 27 patients were treated at the highest dosage level (6.0 mg/m2/hr). Using the World Federation of Neurological Surgeons scale for subarachnoid hemorrhage, at admission 18 patients were Grade I, 15 were Grade II, 6 were Grade III, and 3 were Grade IV. Five patients (12%) developed clinical signs of deterioration suggestive of cerebral ischemia with concomitant evidence of vasospasm on arteriography. These patients were all treated with hypervolemic hypertensive therapy. Only one patient (2%) developed an infarction from vasospasm. Two patients developed symptomatic hydrocephalus requiring ventriculoperitoneal shunting, and a third patient required a temporary ventriculostomy. The 3-month postoperative outcomes were excellent. Three patients (7%) rebled. Three patients died, two from rebleeding of the aneurysm and one who never regained consciousness from the initial hemorrhage.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Ruptured vertebrobasilar dissecting aneurysm is usually treated surgically because rebleeding negatively affects outcome. However, the risk of rebleeding decreases markedly once several hours have passed from the initial bleeding. Moreover, surgery-related complications are not rare. We describe seven patients with ruptured vertebrobasilar dissecting aneurysm. To prevent rebleeding during the acute stage, we treated all seven patients conservatively with fentanyl instead of emergency surgery. During the follow-up period (mean 20 months), no patient suffered rebleeding. Conservative treatment with fentanyl administration may be a good option for management of ruptured vertebrobasilar dissecting aneurysm during the acute stage. 相似文献

Seizures and seizure-like activity may occur in patients experiencing aneurysmal subarachnoid hemorrhage. Treatment of these
events with prophylactic antiepileptic drugs remains controversial. An electronic literature search was conducted for English
language articles describing the incidence and treatment of seizures after aneurysmal subarachnoid hemorrhage from 1980 to
October 2010. A total of 56 articles were included in this review. Seizures often occur at the time of initial presentation
or aneurysmal rebleeding before aneurysm treatment. Seizures occur in about 2% of patients after invasive aneurysm treatment,
with a higher incidence after surgical clipping compared with endovascular repair. Non-convulsive seizures should be considered
in patients with poor neurological status or deterioration. Seizure prophylaxis with antiepileptic drugs is controversial,
with limited data available for developing recommendations. While antiepileptic drug use has been linked to worse prognosis,
studies have evaluated treatment with almost exclusively phenytoin. When prophylaxis is used, 3-day treatment seems to provide
similar seizure prevention with better outcome compared with longer-term treatment. 相似文献

Does treatment modality of intracranial ruptured aneurysms influence the incidence of cerebral vasospasm and clinical outcome? 总被引:3,自引:0,他引:3

BACKGROUND: Cerebral vasospasm is the most common cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage (SAH). This study is designed to determine whether the incidence of symptomatic vasospasm and the overall clinical outcome differ between patients treated with surgical clipping compared with endovascular obliteration of aneurysms. METHODS: In this prospective study, 98 patients with aneurysmal SAH were treated. Seventy-two patients underwent surgery and clipping and 26 had coil embolization. The incidence of symptomatic vasospasm, permanent neurologic deficit due to vasospasm and clinical outcome were analyzed. Patients with better clinical and radiological grades (World Federation of Neurological Surgeons grades I-III and Fisher grades I-III) were analyzed separately. RESULTS: Symptomatic vasospasm occurred in 22% of the patients; 25% in the surgical group and 15% in the endovascular group. Nine percent of the patients in the surgical group and 7% in the endovascular group suffered ischemic infarction with permanent neurological deficit. These differences did not reach statistical significance (p = 0.42). For patients with better clinical and radiological grades, no significant difference was found for the rate of symptomatic vasospasm; 23% in the surgical and 12% in the endovascular group (p = 0.49). The overall clinical outcome was comparable in both groups, with no difference in the likelihood of a Glasgow Outcome Scale score of 3 or less (15% in the surgical and 16% in the endovascular group; p = 0.87). The same results for outcome were obtained for the subgroup of patients with better clinical grades on admission. CONCLUSION: Symptomatic vasospasm and ischemic infarction rate seem comparable in both groups, even for patients with better clinical and radiological admission grades. There is no significant difference in the overall clinical outcome at the long-term follow-up between both groups. 相似文献

Method The 101 cases of grade Ⅰ~Ⅲ patients according to the classification of Hunt and Hess with early surgical treatment were devided into preoperative external lumbar drainage group(47 cases) and postoperative external lumbar drainage group(54 cases).Outcome of patients with different external drainage of cerebrospinal fluid was analyzed. Results There was no case of aneurysm rebleeding could be associated with preoperative spinal drain placement. Tne incidences of intraoperative aneurysm rapture in preoperative external lumbar drainage group was 8. 5%,which was lower than 11. 1% in postoperative external lumbar drainage group. The incidences of symptomatic cerebral vasospasm and chronic hydrocephalus in preoperative external lumbar drainage group were 12. 8% and 12.8% ,which were lower than 20. 4% and 14. 8% in postoperative external lumbar drainage group. There all were not significant differences between the two groups. Conclusions Preoperative external lumbar drainage wont increase a risk of rebleeding for grade Ⅰ~Ⅲ patients with aneurysmal SAH undergoing early surg ery. Furthermore, it can decrease the incidences of symptomatic cerebral vasospasm and chronic hydrocephalus,which is a safe and useful method of removing bloody cerebrospinal fluid. 相似文献

Outcome in elderly patients with ruptured intracranial aneurysm 总被引:2,自引:0,他引:2
Sixty-nine elderly patients over 65 years old with ruptured aneurysms had a significantly worse outcome than 192 younger patients with respect to overall management results and operative results (p less than 0.01). The results of an early operation were better in the elderly patients with grade I-III than in those receiving a delayed operation. Concomitant diseases significantly influenced the results in elderly patients (p less than 0.05). It is possible that an early operation results in the better outcome in elderly patients by decreasing the incidence of delayed ischemic complications and preventing rebleeding. 相似文献

BACKGROUND: Aneurysm rebleeding has historically been an important cause of mortality after subarachnoid hemorrhage (SAH). OBJECTIVE: To describe the frequency and impact of rebleeding in the modern era of aneurysm care, which emphasizes early surgical or endovascular treatment. DESIGN: Inception cohort. SETTING: Tertiary care medical center. PATIENTS: A total of 574 patients enrolled in the Columbia University SAH Outcomes Project between August 1996 and June 2002. Early aneurysm repair was performed whenever feasible. MAIN OUTCOME MEASURES: Rebleeding was defined by prespecified clinical and radiographic criteria, excluding prehospital, intraprocedural, and postrepair events. Functional outcome was assessed at 3 months with the modified Rankin Scale. Multiple logistic regression was used to identify predictors of rebleeding, poor functional outcome, and mortality. RESULTS: Rebleeding occurred in 40 (6.9%) of the 574 patients; most cases (73%) occurred within 3 days of ictus. Hunt-Hess grade on admission (odds ratio [OR], 1.92 per grade; 95% confidence interval [CI], 1.33-2.75; P<.001) and maximal aneurysm diameter (OR, 1.07/mm; 95% CI, 1.01-1.13; P = .005) were independent predictors of rebleeding. After controlling for Hunt-Hess grade and aneurysm size, rebleeding was associated with a markedly reduced chance of survival with functional independence (modified Rankin Scale score, =4; OR, 0.08; 95% CI, 0.02-0.34) at 3 months. CONCLUSIONS: Despite an aggressive management strategy, rebleeding still occurred in 6.9% of patients and was associated with a dismal outcome. Poor Hunt-Hess grade and larger aneurysm size are related to rebleeding. Pharmacologic therapy to reduce the risk of rebleeding before aneurysm repair, particularly in patients with poor grade neurologic status and large aneurysms, deserves renewed attention. 相似文献

In the current era of early surgery, there has been little interest in the use of antifibrinolytic therapy to prevent rebleeding
after aneurysmal subarachnoid hemorrhage (aSAH). Older studies demonstrated that antifibrinolytics can reduce rebleeding,
but long-term therapy results in increased cerebral ischemia from vasospasm, leading to no appreciable effect on mortality.
While early surgery would seem to obviate the need for long-term antifibrinolytic use, a subgroup of patients may benefit
from early therapy. The rate of pre-operative rebleeding may be as high as 9–17%, causing significant morbidity and mortality.
Short-term use of antifibrinolytic agents (less than 3 days) in the presence of calcium channel blocking therapy has shown
promising results. A randomized clinical trial of early antifibrinolytic therapy conducted in 2002 showed a significant decrease
in rebleeding and a non-significant decrease in overall mortality. In this review, we examine the clinical pharmacology, dosing,
monitoring, complications, and side effects of antifibrinolytic treatment. We conclude that early short-term antifibrinolytic
therapy might be a reasonable strategy to prevent acute rebleeding and improve long-term outcome in aSAH patients. Additional
randomized clinical trials are necessary to determine whether this management strategy is effective. 相似文献

A study was conducted on the medical records of 353 patients who died of a subarachnoid hemorrhage (SAH) and who were submitted to autopsy over the last 10 years. SAH was associated with arterial hypertension in 180 (51%) cases, with ruptured aneurysms in 102 (28.9%), and with other pathologies in 71 (20.1%). The patients with hemorrhage associated with arterial hypertension were mostly males, and those with hemorrhage due to aneurysms were mostly females. Of the patients with aneurysms, 36 (35.3%) had aneurysms in the anterior communicating artery, 30 (29.4%) in the internal carotid artery, and 23 (22.6%) in the middle cerebral artery. Among the patients with aneurysms who suffered rebleeding and vasospasm, 59.1% and 61.5%, respectively, were classified as grade I and II upon admission, and all evolved toward grade IV after these complications. Vasospasm predominated from the 3rd to the 10th day after hemorrhage, and rebleeding from the 9 to 16th day and both were most frequent among patients with aneurysms of the anterior communicant artery. Sixty eight percent of the patients with aneurysms died during the first 9 days after hemorrhage. Because of our conduct was to operate systematically late, a considerable number of patients lost the opportunity to be treated surgically with possible favorable evolution due to vasospasm or rebleeding. 相似文献

BACKGROUND AND PURPOSE: The purpose of this community-based study was to evaluate temporal changes in surgical and management outcomes in patients with aneurysmal subarachnoid hemorrhage (SAH). METHODS: The subjects were 358 patients with aneurysmal SAH who were treated during the 19-year period from 1980 to 1998 in Izumo City, Japan. We compared data during the 9-year period 1990-1998 (period B; 188 patients) with those during the 10-year period 1980-1989 (period A; 170 patients). RESULTS: The proportion of patients 80 years of age or older or those with World Federation of Neurosurgical Societies grade V increased significantly (period A, 5 and 25%; period B, 18 and 35%, respectively). The operability rate did not change for patients 69 years of age or younger, whereas it increased significantly for those 70-79 years of age (period A, 48%; period B, 72%). The 6-month and 2-year case fatality rates in surgically treated patients decreased significantly (period A, 12 and 20%; period B, 2 and 8%, respectively), whereas they were virtually unchanged for overall management (period A, 41 and 46%; period B, 38 and 42%, respectively). In patients who underwent surgery, the incidence of permanent symptomatic vasospasm decreased from 21% during period A to 11% during period B, and there was no death from vasospasm in the later period. However, no significant difference was found in the functional outcome between the two periods, regardless of whether surgery was performed. The most important determinants of 6-month and 2-year survival rates were grade on admission, rebleeding and the site of the ruptured aneurysms. Age was also a significant predictor of the 6-month case fatality rate. CONCLUSIONS: For patients with SAH who underwent surgery, there were trends towards decreases in the case fatality rate and in the incidence of permanent symptomatic vasospasm. Nevertheless, the overall management outcome was still unsatisfactory, mainly because of increasing numbers of very elderly and/or high-risk patients. . 相似文献

Background
Epsilon aminocaproic acid (EACA) has been used in the past to prevent cerebral aneurysm rerupture. Recent studies have indicated that short-term treatment with EACA can lower rebleeding rates without significantly increasing ischemic or thrombotic complications or permanent shunt rates. The goal of this study is to determine the efficacy of EACA in the prevention of aneurysm rerupture at a high volume subarachnoid hemorrhage center.Methods
We conducted a retrospective study of 355 consecutive subarachnoid hemorrhage patients over a 2-year period under our current protocol for EACA use. Patients were divided by presentation time to our institution and whether the patient received EACA. The primary endpoints of the study were rebleeding rates, ischemic complications, thrombotic complications, vasospasm, shunt rates, and outcomes.Results
Rerupture rates were reduced by half in the entire pool of patients on EACA after controlling for Hunt and Hess Scores and Fisher Scores. In patients who received early aneurysm treatment, this effect persisted but was non-statistically significant due to the small numbers of reruptures. In addition, there was no evidence to suggest that EACA increased ischemic or thrombotic complications, vasospasm, or VPS rates. In patients presenting earlier than 24 h to our institution, there was a non-significant trend toward worse outcomes after EACA use. This trend was reversed in patients arriving after 24 h.Conclusion
There is evidence to suggest that EACA is protective from aneurysm rerupture without significant ischemic or thrombotic complications when used for less than 72 h. However, if the aneurysm is treated, this effect is modest indicating that early aneurysm treatment remains the gold standard for rerupture prevention. 相似文献20.
Results of the surgical treatment of patients with single aneurysms of the middle cerebral artery 总被引:1,自引:0,他引:1
A Marchel 《Neurologia i neurochirurgia polska》1987,21(6):534-540
Results are presented of surgical treatment of patients with isolated aneurysms on the middle cerebral artery on the basis of the material of the Department of Neurosurgery, Medical Academy in Warsaw in the years 1975-1981. The material included 161 surgically treated patients out of 179 treated in this time period for diagnosed isolated aneurysm of this artery. The frequency of this aneurysm was 23.2% in this material. The operative mortality was 8.9%, and the results were very good and good in 85.7% of cases. The number of past bleedings from the aneurysm, the clinical state of the patients, the timing of the operation, presence of intracerebral haematoma, intraoperative rupture of the aneurysm and postoperative vasospasm were factors having a significant unfavourable influence on the early postoperative results. Vasospasm was the most frequent postoperative complication observed in 15.2% of cases. The clinical state of the patient and the mode of aneurysm management had a statistically significant effect on the late results of surgical treatment. In 6 cases (6.1%) subarachnoid bleeding appeared after the operation and in 5 of them aneurysm wall had to be strengthened (wrapping). 相似文献
