Middle Cerebral Artery Aneurysms

OBJECT Intrasylvian hematoma (ISH) is a subtype of intracranial hematoma caused by aneurysmal rupture and often presents with a poor initial neurological grade; it is not well studied. The aim of this study was to elucidate outcomes of aneurysmal subarachnoid hemorrhage (SAH) with ISH. METHODS Data for 97 patients with poor-grade SAH (World Federation of Neurosurgical Societies Grade IV or V) were retrospectively analyzed from a single-center, prospective, observational cohort database. Ultra-early surgical clipping, removal of hematoma, external decompression for brain swelling, and prevention of vasospasm by cisternal irrigation with milrinone were combined as an aggressive treatment. Characteristics and clinical courses of SAH with ISH were identified. The authors also evaluated any correlations between poor admission-grade SAH and ISH with good functional outcome. RESULTS Patients with poor admission-grade SAH and with ISH were more likely to have initial cerebral edema (p < 0.001, Mann-Whitney U-test), which significantly resolved overtime (p < 0.001, Mann-Whitney U-test). These patients had a better chance of functional survival (modified Rankin Scale scores of 1–3; OR 5.75; 95% CI 1.36–24.3; p = 0.017) at 6 months after hospital discharge, after adjustment for potential confounders such as younger age and better initial neurological grade by multivariable analysis. CONCLUSIONS ISH predicted good functional recovery from poor-grade aneurysmal SAH.

ABSTRACT BACKGROUND: There is no consensus regarding the optimal timing for surgery for poor-grade aneurysmal subarachnoid hemorrhage. OBJECTIVE: To retrospectively evaluate variation in patient characteristics and outcomes between early and delayed surgery groups. METHODS: Poor-grade aneurysmal subarachnoid hemorrhage was defined as a World Federation of Neurosurgical Societies grade of IV or V after resuscitation. Early surgery was defined as surgery performed within 72 hours of ictus, and delayed surgery was defined as surgery after 72 hours. Outcomes were assessed by modified Rankin score. The mean time of follow-up was 12.5 ± 3.4 months. RESULTS: Of the 118 patients included in the study, 80 (68%) underwent early surgery and 38 (32%) underwent delayed surgery. Patients with brain herniation (P &lt; .001) and a lower Fisher grade (P = .02) more often underwent early surgery. Patients in the early group more often underwent decompressive craniectomy (P &lt; .001). Postoperative complications and length of hospital stay did not differ, and outcomes were similar between the 2 groups. Forty (34%) patients had an excellent outcome (modified Rankin score 0-1). Multivariate analysis showed a slight trend toward an excellent outcome in the early surgery group. Younger age, World Federation of Neurosurgical Societies grade IV after resuscitation, and middle cerebral artery aneurysms were independent predictors of an excellent outcome. CONCLUSION: Although patients with brain herniation and a lower Fisher grade were more likely to undergo early surgery, there was a slight trend toward an excellent outcome in the early surgery group. Patients with a younger age, World Federation of Neurosurgical Societies grade IV after resuscitation, and middle cerebral artery aneurysms were more likely to experience an excellent outcome.

OBJECTIVEDiverse treatment results are observed in patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH). Significant initial perfusion compromise is thought to predict a worse treatment outcome, but this has scant support in the literature. In this cohort study, the authors correlate the treatment outcomes with a novel poor-outcome imaging predictor representing impaired cerebral perfusion on initial CT angiography (CTA).METHODSThe authors reviewed the treatment results of 148 patients with poor-grade aSAH treated at a single tertiary referral center between 2007 and 2016. Patients with the “venous delay” phenomenon on initial CTA were identified. The outcome assessments used the modified Rankin Scale (mRS) at the 3rd month after aSAH. Factors that may have had an impact on outcome were retrospectively analyzed.RESULTSCompared with previously identified outcome predictors, the venous delay phenomenon on initial CTA was found to have the strongest correlation with posttreatment outcomes on both univariable (p < 0.0001) and multivariable analysis (OR 4.480, 95% CI 1.565–12.826; p = 0.0052). Older age and a higher Hunt and Hess grade at presentation were other factors that were associated with poor outcome, defined as an mRS score of 3 to 6.CONCLUSIONSThe venous delay phenomenon on initial CTA can serve as an imaging predictor for worse functional outcome and may aid in decision making when treating patients with poor-grade aSAH.

ABSTRACT OBJECTIVE To elucidate the effect of treatment timing on procedural clinical outcomes after aneurysmal subarachnoid hemorrhage (SAH) for patients treated by endosaccular coil embolization. METHODS A group of 327 patients who were consecutively treated, during a 46-month period, for ruptured intracranial aneurysms by coil embolization within 30 days after SAH were evaluated. Outcomes were assessed by comparing immediate pretreatment World Federation of Neurological Surgeons (WFNS) grades, 72-hour posttreatment WFNS grades, and modified Glasgow Outcome Scale scores at 6 months for patients treated within 48 hours (Group 1), 3 to 10 days (Group 2), or 11 to 30 days (Group 3) after SAH. RESULTS The three interval-to-treatment groups included 33, 38, and 29% of the patients, respectively. Before treatment, 70% of the patients in Group 1, 78% of those in Group 2, and 83% of those in Group 3 were in good clinical grades (i.e., WFNS Grade 1 or 2). After coil embolization, the WFNS grades were either unchanged or improved for 93.5% of the patients in Group 1, 89.5% of those in Group 2, and 91.5% of those in Group 3. After 6 months, 81.3% of the patients in Group 1 experienced good outcomes (modified Glasgow Outcome Scale scores of 1 or 2), as did 84% of those in Group 2 and 80% of those in Group 3. No statistical difference was demonstrated between the three groups when they were compared for these two variables. CONCLUSION The interval between endovascular treatment and SAH did not affect periprocedural morbidity rates or 6-month outcomes. Coil embolization should therefore be performed as early as possible after aneurysmal SAH, to prevent aneurysmal rerupture.

Abstract BACKGROUND The relationships between lipoprotein-associated phospholipase A2 (Lp-PLA2) level, vasospasm, and clinical outcome of patients with aneurysmal subarachnoid hemorrhage (aSAH) are still unclear. OBJECTIVE To identify the associations between admission Lp-PLA2 and vasospasm following subarachnoid hemorrhage and the clinical outcome of aSAH. METHODS A total of 103 aSAH patients who had Lp-PLA2 level obtained within 24 h postbleeding were included. The relationships between Lp-PLA2 level, vasospasm, and clinical outcome were analyzed. RESULTS Vasospasm was observed in 52 patients (50.49%). Patients with vasospasm had significantly higher Lp-PLA2 level than those without (P &lt; .001). Both modified Fisher grade (P = .014) and Lp-PLA2 level (P &lt; .001) were significant predictors associated with vasospasm. The Z test revealed that power of Lp-PLA2 was significantly higher than that of modified Fisher grade in predicting vasospasm (Z = 2.499, P = .012). At 6-mo follow-up, 44 patients (42.72%) had unfavorable outcome and 36 patients (34.95%) died. The World Federation of Neurosurgical Societies (WFNS) grade and Lp-PLA2 level were both significant predictors associated with 6-mo unfavorable outcome and mortality (all P &lt; .001). The predictive values of Lp-PLA2 for unfavorable outcome and mortality at 6-mo tended to be lower than those of the WFNS grade, but the differences were not statistically significant (P = .366 and 0.115, respectively). Poor-grade patients having Lp-PLA2 &gt; 200 μg/L had significantly worse 6-mo survival rate than poor-grade patients having Lp-PLA2 ≤ 200 μg/L (P = .001). CONCLUSION The Lp-PLA2 might be useful as a novel predictor in aSAH patients. A total of 30 poor-grade patients; those with elevated Lp-PLA2 level have higher risk of 6-mo mortality compared to those without.

Abstract OBJECTIVE We sought to determine whether the rebleeding rate in poor-grade patients justified a period of supportive observation before selective treatment and whether unselected ultraearly surgery would lead to acceptable results. METHODS A prospectively audited, nonselected series of 177 consecutive poor-grade (i.e., World Federation of Neurological Surgeons Grades IV and V) patients with aneurysmal subarachnoid hemorrhage managed during a 9-year period was analyzed. A management policy of aggressive ultraearly surgery (not selected by age or by grade) was followed. Coiling was not available. Outcomes were assessed at 3 months. RESULTS Despite the aggressive management policy, surgery could be performed in only 132 poor-grade patients (75%). Twenty percent of all patients were 70 years of age or older (15% of the surgical cases). All surgery was performed within 12 hours of subarachnoid hemorrhage (majority &lt;6 h). Preoperative rebleeding occurred within the first 12 hours (&gt;85% within 6 h) in 20% of the patients, which is four times the rate found in good-grade patients managed according to the same policy. Outcome assessment performed at 3 months in the 132 poor-grade surgical patients revealed that 40% were independent, 15% were dependent, and 45% had died. There was no significant difference in outcomes for young and old (70+ yr) poor-grade surgical patients (P &gt; 0.05). CONCLUSION The high ultraearly rebleeding rate indicates a need to urgently secure the ruptured aneurysm by performing surgery or coiling, and this indication is more pronounced for poor-grade patients than for good-grade patients. The outcome results of ultraearly surgery indicate that a nonselective policy does not lead to a large number of dependent survivors, even among elderly poor-grade patients.

Object The association of vitreous and/or subhyaloid hemorrhage with aneurysmal subarachnoid hemorrhage (SAH) has been frequently identified since the original description by Terson in 1900. In this prospective clinical study the authors examined the actual incidence of Terson hemorrhage in patients suffering aneurysmal SAH, they attempted to identify those parameters that could predispose its development, and they evaluated its prognostic significance in the overall patients' outcome. Methods A total of 174 patients suffering aneurysmal SAH were included in this study. The admitting Glasgow Coma Scale scores (GCS), World Federation of Neurological Societies (WFNS) scale scores, Hunt and Hess grades, and Fisher grades were recorded. A careful ophthalmological evaluation was performed in all participants. The exact anatomical locations and the largest diameter of the dome of the ruptured aneurysms were also recorded. Surgical clipping or endovascular coiling was used in 165 patients. Clinical outcome was evaluated at discharge from the hospital by using the Glasgow Outcome Scale and the modified Rankin Scale. Periodic ophthalmological evaluations were performed for 2 years. Results In this series, the observed incidence of Terson hemorrhage was 12.1%. Statistical analysis of our data demonstrated that patients with low GCS scores and high WFNS scores, Hunt and Hess grades, and Fisher grades had an increased incidence of Terson hemorrhage. The mortality rate for patients with Terson hemorrhage was 28.6%, whereas that for patients without Terson hemorrhage was 2.0%. Moreover, patients with Terson hemorrhage who survived had significantly worse outcomes than those in patients without Terson hemorrhage. Conclusions Terson hemorrhage constitutes a common SAH-associated complication. Its incidence is increased in patients with low GCS and high WFNS scores, and high Hunt and Hess and Fisher grades. Its presence is associated with increased mortality and morbidity rates.

Abstract Background Patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH), defined as World Federation of Neurosurgical Societies (WFNS) grade IV-V has high rates of disability and mortality. The objective of this research is to prognosticate outcomes of poor-grade aSAH accurately. Methods A total of 147 poor-grade aSAH patients in our center were enrolled. Risk variables identified by multivariate logistic regression were used to devise the scoring model (total score of 0–9 points). The score values were estimated according to β coefficients. A cohort of 68 patients from another institute was used to validate the model. Results Multivariate analysis revealed that modified Fisher grade above II (odds ratio [OR], 2.972; p = 0.034), age ≥ 65 years (OR, 3.534; p = 0.006), conservative treatment (OR, 5.078; p = 0.019), WFNS Grade V (OR, 2.638; p = 0.029), delayed cerebral ischemia (OR, 3.170; p = 0.016), shunt-dependent hydrocephalus (OR, 3.202; p = 0.032) and cerebral herniation (OR, 7.337; p < 0.001) were significant predictors of poor prognosis (modified Rankin Scale [mRS] ≥ 3). By integration of above factors, a scoring system was constructed and divided poor-grade aSAH patients into three categories: low risk (0–1 point), intermediate risk (2–3 points) and high risk (4–9 points), with risk of poor prognosis being 11%, 52% and 87% respectively (P < 0.001). The area under the curve in derivation cohort was 0.844 (p < 0.001; 95% CI, 0.778–0.909). AUC in validation cohort was 0.831 (p < 0.001; 95% CI, 0.732–0.929). Conclusions The new scoring model could improve prognostication of prognosis and help decision-making for subsequent complement treatment.

OBJECTIVEThe objective of this study was to measure the concentration of nimodipine in CSF and plasma after intraventricular injection of a sustained-release formulation of nimodipine (EG-1962) in patients with aneurysmal subarachnoid hemorrhage (SAH).METHODSPatients with SAH repaired by clip placement or coil embolization were randomized to EG-1962 or oral nimodipine. Patients were classified as grade 2–4 on the World Federation of Neurosurgical Societies grading scale for SAH and had an external ventricular drain inserted as part of their standard of care. Cohorts of 12 patients received 100–1200 mg of EG-1962 as a single intraventricular injection (9 per cohort) or they remained on oral nimodipine (3 per cohort). Plasma and CSF were collected from each patient for measurement of nimodipine concentrations and calculation of maximum plasma and CSF concentration, area under the concentration-time curve from day 0 to 14, and steady-state concentration.RESULTSFifty-four patients in North America were randomized to EG-1962 and 18 to oral nimodipine. Plasma concentrations increased with escalating doses of EG-1962, remained stable for 14 to 21 days, and were detectable at day 30. Plasma concentrations in the oral nimodipine group were more variable than for EG-1962 and were approximately equal to those occurring at the EG-1962 800-mg dose. CSF concentrations of nimodipine in the EG-1962 groups were 2–3 orders of magnitude higher than in the oral nimodipine group, in which nimodipine was only detected at low concentrations in 10% (21/213) of samples. In the EG-1962 groups, CSF nimodipine concentrations were 1000 times higher than plasma concentrations.CONCLUSIONSPlasma concentrations of nimodipine similar to those achieved with oral nimodipine and lasting for 21 days could be achieved after a single intraventricular injection of EG-1962. The CSF concentrations from EG-1962, however, were at least 2 orders of magnitude higher than those with oral nimodipine. These results supported a phase 3 study that demonstrated a favorable safety profile for EG-1962 but yielded inconclusive efficacy results due to notable differences in clinical outcome based on baseline disease severity.Clinical trial registration no.: NCT01893190 (ClinicalTrials.gov).
