Abstract
BACKGROUND Delayed cerebral ischaemia (DCI) is a major cause of morbidity and mortality after aneurysmal subarachnoid haemorrhage (aSAH). Chemical angioplasty (CA) and transluminal balloon angioplasty (TBA) are used to treat patients with refractory vasospasm causing DCI. Multi-modal monitoring including brain tissue oxygenation (PbtO2) is routinely used at this centre for early detection and management of DCI following aSAH. In this single-centre pilot study, we are comparing these two treatment modalities and their effects on PbtO2. METHODS Retrospective case series of patients with DCI who had PbtO2 monitoring as part of their multimodality monitoring and underwent either CA or TBA combined with CA. PbtO2 values were recorded from intra-parenchymal Raumedic NEUROVENT-PTO® probes. Data were continuously collected and downloaded as second-by-second data. Comparisons were made between pre-angioplasty PbtO2 and post-angioplasty PbtO2 median values (4 h before angioplasty, 4 h after and 12 h after). RESULTS There were immediate significant improvements in PbtO2 at the start of intervention in both groups. PbtO2 then increased by 13 mmHg in the CA group and 15 mmHg in the TBA plus CA group in the first 4 h post-intervention. This improvement in PbtO2 was sustained for the TBA plus CA group but not the CA group. CONCLUSION Combined balloon plus chemical angioplasty results in more sustained improvement in brain tissue oxygenation compared with chemical angioplasty alone. Our findings suggest that PbtO2 is a useful tool for monitoring the response to angioplasty in vasospasm.

Abstract
Delayed cerebral ischemia (DCI) is one of the most important complications of subarachnoid hemorrhage. Despite lack of prospective evidence, medical rescue interventions for DCI include hemodynamic augmentation using vasopressors or inotropes, with limited guidance on specific blood pressure and hemodynamic parameters. For DCI refractory to medical interventions, endovascular rescue therapies (ERTs), including intraarterial (IA) vasodilators and percutaneous transluminal balloon angioplasty, are the cornerstone of management. Although there are no randomized controlled trials assessing the efficacy of ERTs for DCI and their impact on subarachnoid hemorrhage outcomes, survey studies suggest that they are widely used in clinical practice with significant variability worldwide. IA vasodilators are first line ERTs, with better safety profiles and access to distal vasculature. The most commonly used IA vasodilators include calcium channel blockers, with milrinone gaining popularity in more recent publications. Balloon angioplasty achieves better vasodilation compared with IA vasodilators but is associated with higher risk of life-threatening vascular complications and is reserved for proximal severe refractory vasospasm. The existing literature on DCI rescue therapies is limited by small sample sizes, significant variability in patient populations, lack of standardized methodology, variable definitions of DCI, poorly reported outcomes, lack of long-term functional, cognitive, and patient-centered outcomes, and lack of control groups. Therefore, our current ability to interpret clinical results and make reliable recommendations regarding the use of rescue therapies is limited. This review summarizes existing literature on rescue therapies for DCI, provides practical guidance, and identifies future research needs.

Abstract
Background This study provides a comprehensive overview of the management of postoperative vasospasm after skull base surgeries. This phenomenon is rare but can be of serious sequelae. Methods Medline, Embase, and PubMed Central were searched, along with examining the references of the included studies. Only case reports and series that reported vasospasm following a skull base pathology were incorporated. Cases with pathologies other than skull base, subarachnoid hemorrhage, aneurysm, and reversible cerebral vasoconstriction syndrome were excluded from the study. Quantitative data were presented as mean (Standard Deviation) or median (range), accordingly, while qualitative data were presented as frequency (percentage). Chi- square test and one-way analysis of variance were used to assess for any association between the different factors and patient outcomes. Results We had a total of 42 cases extracted from the literature. The mean age was 40.1 (±16.1) with approximately equal males and females (19 [45.2%] and 23 [54.8%], respectively). The time to develop vasospasm after the surgery was 7 days (±3.7). Most of the cases were diagnosed by either angiogram or magnetic resonance angiography. Seventeen of the 42 patients had pituitary adenoma as the pathology. Anterior circulation was nearly affected in all patients. For management, most patients received pharmacological with supportive management. Twenty-three patients had an incomplete recovery as a result of vasospasm. Conclusion Vasospasm following skull base operations can affect males and females, and most patients in this review were middle-aged adults. The outcome of patients varies; however, most patients did not achieve a full recovery. There was no correlation between any factors and the outcome.

Abstract
OBJECTIVE Bibliometric analysis reflects the scientific recognition and influential performance of a published article within its field. Our aim is to identify and analyze the top 100 most-cited articles on cerebral vasospasm. METHODS A title-specific search was carried out using the Scopus database. The top 100 cited articles including the keywords "Cerebral Vasospasm" AND "Vasospasm" were retrieved and stratified in a descending order: title, authors, institution, publishing journal, country of origin, year of publication, and topic of each article were studied. RESULTS The top 100 articles have an accumulative citation count of 20,972, with 209 average citations per article. Publication dates ranged from 1968 to 2012, with the most productive years between 1998 and 2005. Clinical studies are the most frequent category, followed by pathophysiology. The list includes 7 clinical trials, which received accumulative citations of 1525. The top cited article had received 2109 citations, with 52.7 citations per year. The top 100 articles were published across 14 countries, with most originating from the United States. The lead research institution was the University of Alberta. The most used journal was Journal of Neurosurgery. CONCLUSIONS Bibliometric analysis has garnered major interest in recent years. It shows the publication trends, knowledge evolution, and evidence-based practice throughout the years. The collection of highly cited articles may assist physicians in gaining a better understanding of the nature of cerebral vasospasm and optimize their clinical practice.

Abstract
The novel coronavirus disease 2019 (COVID-19) has emerged as a global pandemic. A significant number of these patients would present to hospitals with neurological manifestations and neurosurgical emergencies requiring urgent treatment. The anesthesiologists should be prepared to manage these cases in an efficient and timely manner in the operating room, intensive care units, and interventional neuroradiology suites. The clinical course of the disease is in an evolving stage. As we acquire more knowledge about COVID-19, new recommendations and guidelines are being formulated and regularly updated. This article discusses the anesthetic management of urgent neurosurgical and neurointerventional procedures. In addition, a brief overview of intrahospital transport of neurologically injured patients has been addressed.

Abstract
BACKGROUND Delayed cerebral ischemia is one of the leading causes of death and disability in patients with subarachnoid hemorrhage (SAH). Transluminal balloon angioplasty (TBA) is a therapeutic option for vasospasms affecting proximal intracranial arteries. METHODS Aim of this study was to report our experience using the Scepter C balloon catheter in the treatment of cerebral vasospasms due to SAH and evaluate the postprocedural result with the iFlow tool. We reviewed cases of patients treated at our hospital from 2014 to 2018. Patients were screened with transcranial doppler sonography (TCD) and multimodal computed tomography. In case of significant vasospasms, patients were transferred to the angiography suite and treated. We used the iFlow tool to quantify and evaluate the angiographic results by measuring and comparing peak density values on angiograms before and after the mechanical dilation. RESULTS The use of the Scepter C balloon catheter was feasible in all cases. Vasospasms of the anterior cerebral artery were treated in ten cases. We didn't observe complications or vasospasm recurrences of the treated arteries. The temporal difference between distal vessels and the proximal reference vessel was significantly reduced from a mean of 53%, prior to dilatation, to 26% after the treatment. The difference between pre-dilatation and post-dilatation values was statistically significant for the anterior circulation at the proximal as well as at the distal vessels. CONCLUSIONS We successfully treated endovascularly patients suffering from cerebral vasospasms refractory to medical treatment using the Scepter C balloon catheter. We didn't observe any complications. The therapeutic effect could be easily and reliably assessed with the iFlow tool.

Transluminal balloon angioplasty for cerebral vasospasm after spontaneous subarachnoid hemorrhage: A single-center experience. Clin Neurol Neurosurg 2019; 188:105590.

Abstract
OBJECTIVES After spontaneous subarachnoid hemorrhage (sSAH), cerebral vasospasm (CVS) is a common complication, potentially resulting in infarction mainly responsible for a poor outcome. Intra-arterial vasodilators lead to transient increase of brain perfusion, but only transluminal balloon angioplasty (TBA) promises longer-lasting effects, though it poses the risk of severe complications. Until now, the precise impact of TBA on the course of CVS is not yet finally clarified. Thus we aimed to identify risk factors of recurrent CVS and vasospasm-related infarction following TBA. PATIENTS AND METHODS We analyzed 35 patients with CVS after sSAH who received TBA (41 procedures, 99 vessel segments). Gender, age, WFNS grade and Fisher scale, occurrence of intraventricular and intracerebral hemorrhage, localization of the aneurysm and the initial treatment modality were obtained. We assessed functional outcome after 3 months and in-hospital mortality. TBA was analyzed concerning time point, localization, technique, complications and angiographic response. Furthermore, recurrence of CVS and vasospasm-related infarction after TBA were described and risk factors were identified with logistic regression analyses. RESULTS In 7 of 35 patients (20%) and in 16 of 99 vessel segments (16%) previously treated with TBA, we found recurrent CVS. Vasospasm-related infarction occurred in 18 cases (18%) in the arterial territories of the TBA-treated vessel segments. The angiographic effect after TBA was mostly classified as good (87%), good response was negatively associated with recurrent CVS (p = 0.004) and vasospasm-related infarction (p = 0.001). We identified only the male gender as a risk factor for vasospasm-related infarction after TBA (p = 0.040). In connection with TBA, only one complication occurred (intracranial dissection). CONCLUSION Our data support TBA as a safe and effective therapy for CVS. Nevertheless, recurrent CVS and vasospasm-related infarction were common after TBA and not predictable by clinical conditions on admission or the localization of CVS. A moderate or poor angiographic response after TBA was identified as a risk factor for both, recurrent CVS and vasospasm-related infarction, while male gender was associated with a higher risk of vasospasm-related infarction. Our results augment the still sparse evidence concerning optimal patient selection for this method and provide new aspects for individual therapy decisions.

Abstract
Background and Purpose- Symptomatic vasospasm is a common cause of morbidity and mortality after subarachnoid hemorrhage. We sought to identify predictors and the long-term impact of treatment failure with hypertensive therapy for symptomatic vasospasm. Methods- We performed a retrospective analysis of 1520 subarachnoid hemorrhage patients prospectively enrolled in the Columbia University SAH Outcomes Project between August 1996 and August 2012. One hundred ninety-eight symptomatic vasospasm patients were treated with vasopressors to raise arterial blood pressure, with and without volume expansion. Treatment response, defined as complete or near-complete resolution of the initial neurological deficit, was adjudicated in weekly meetings of the study team based on serial clinical examination after hypertensive treatment. Outcome was evaluated at 1 year with the modified Rankin Scale. Results- Twenty-one percent of the 198 patients who received hypertensive therapy did not respond to treatment. Treatment failure was associated with an increased risk of death or severe disability at 1 year (modified Rankin Scale score of 4-6; 62% versus 25%; P<0.001). Failure of medical therapy was also associated with an admission troponin I level >0.3 μg/L (64% versus 28%; P=0.001), aneurysm coiling (43% versus 20%; P=0.004), and involvement of >1 symptomatic vascular territory at onset (39% versus 22%; P=0.02). In multivariable analysis, treatment failure was independently associated only with troponin I elevation (adjusted odds ratio, 4.30; 95% CI, 1.69-11.09; P=0.002). Conclusions- Failure to respond to induced hypertension for symptomatic vasospasm threatens 1-year outcome. Subarachnoid hemorrhage patients with symptomatic vasospasm who have elevated initial troponin I levels, indicative of neurogenic cardiac injury, are at twice the risk of medical treatment failure. Expedited endovascular therapy should be considered in these patients.

Abstract
OBJECTIVE Recent large-scale studies describing hospitalization cost trends secondary to aneurysmal subarachnoid hemorrhage (aSAH) in the United States are lacking. We sought to discover the impact of aSAH-related factors upon its hospitalization cost. PATIENTS AND METHODS Patients with a primary diagnosis of aSAH were selected utilizing the National Inpatient Sample. Regression analyses were used to evaluate the impact of aSAH-related factors on hospitalization costs. RESULTS From 2002-2014, 22,831 cases of aSAH were identified. The inflation-adjusted mean cost of hospitalization was $82,514 (standard deviation ± $54,983). The proportion of males was lower (31%), but a higher cost of $3385 (± $685; p < .001) remained compared to females. Median length of hospitalization was 16 days (interquartile range 11-23) and each day increase in hospitalization was associated with a cost increase of $3228 (± $19; p < .001). There was no difference in cost between patients undergoing aneurysmal coiling or clipping. When compared to patients < 40 years old, the increase in cost for patients 40-59 years old was $3829 (± $914; p < .001), and $4573 (± $1033; p < .001) for patients 60-79 years old; however, for patients ≥ 80 years old, there was a decrease in cost of $8124 (± $1722; p < .001). Several central nervous system complications were also associated with increased cost. CONCLUSION aSAH is a significant financial burden on the United States healthcare system. We were able to identify many important factors associated with higher costs, and these results may help us understand resource utilization and develop future cost-reduction strategies.

Intra-Arterial Papaverine-Hydrochloride and Transluminal Balloon Angioplasty for Neurointerventional Management of Delayed-Onset Post-Aneurysmal Subarachnoid Hemorrhage Vasospasm. World Neurosurg 2018; 119:e301-e312. [PMID: 30053563 DOI: 10.1016/j.wneu.2018.07.138] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 07/13/2018] [Accepted: 07/14/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVE After subarachnoid hemorrhage, delayed onset vasospasm can result in devastating ischemic stroke. The phenomenon of delayed cerebral ischemia (DCI) is not yet fully understood, and the correlation of angiographic vasospasm and cerebral infarction is still unclear. Therefore, we investigated the effect of endovascular treatment on the angiographic response and occurrence of DCI. METHODS Eighty patients with subarachnoid hemorrhage and serious cerebral vasospasm underwent endovascular treatment using intra-arterial papaverine-hydrochloride (IAP) or transluminal balloon angioplasty (TBA). The angiographic response and infarction rate were classified using the pre- and postinterventional angiographic images and computed tomography scans. RESULTS In 90% of patients, vasospasm could be improved. In most cases (78.8%), IAP was used. Retreatment after IAP was necessary in 32.9% of patients but never after TBA. A total of 233 vascular territories were treated in 128 procedures. Angiographic improvement was observed in 66.5% of territories, which was significantly associated with early intervention (P = 0.02), the use of TBA (P = 0.01), and the dose of papaverine-hydrochloride (P = 0.01). DCI occurred in 47.5% of the patients. Territorial infarction was associated with a poor Hunt and Hess grade (P = 0.03), day of aneurysm treatment (P = 0.01), severe vasospasm before (P = 0.02) and after (P = 0.03) treatment, and number of interventions (P = 0.01). However, the infarction rate was independent of the angiographic response. CONCLUSION The discrepancy of excellent angiographic results and the high incidence of DCI might stem from an inaccurate or a delayed diagnosis of impending ischemia. In view of the limited time window, optimized peri-interventional management and continuous cerebral multimodality neuromonitoring might be crucial for the ideal timing of endovascular procedures to prevent cerebral infarctions.

Abstract
BACKGROUND AND PURPOSE Delayed cerebral ischemia (DCI) is a complication of aneurysmal subarachnoid hemorrhage (SAH). Arterial cerebral vasospasm (CVS) is discussed as the main pathomechanism for DCI. Due to positive effects of per os nimodipine, intraarterial nimodipine application is used in patients with DCI. Further, percutaneous transluminal balloon angioplasty (PTA) is applied in focal high-grade spasm of intracranial arteries. However, clinical benefits of those techniques are unconfirmed in randomized trials so far, and complications might occur. We analyzed the occurrence of new infarcts in patients with severe CVS treated intra-arterially to assess benefits and risks of those techniques in a large single-center collective. MATERIALS AND METHODS All imaging and clinical data of 88 patients with CVS after SAH and 188 procedures of intraarterial nimodipine infusion and additional PTA in selected cases (18 patients, 20 PTA procedures) treated at our institution were reviewed. In the event of new infarcts after endovascular treatment of CVS, infarct patterns were analyzed to determine the most probable etiology. RESULTS Fifty-three percent of patients developed new cerebral infarction after intraarterial nimodipine and additional PTA in selected cases. Hereunder 47% were caused by persisting CVS. In 6% of patients, 3% of procedures respectively, new infarcts occurred due to complications of the intraarterial treatment including thromboembolism and arterial dissection. Of those, 3% of patients, 2% of procedures respectively, were assigned to thrombembolic complications of digital substraction angiography for intraarterial nimodipine. 17% of all patients treated with PTA (3/18=17%) showed infarction as a complication of PTA (15% of all PTA procedures). In 1% of patients, etiology of new infarction remained unclear. CONCLUSION Ischemic complications occur in about 6% of patients treated intraarterially for CVS, 3% of procedures respectively. Further, to date a benefit for patients treated with this therapy could not be proven. Therefore, intraarterial treatment of CVS should be performed only in carefully selected cases.

Abstract
BACKGROUND Milrinone is an inotropic and vasodilatory drug proven safe for use in treatment of cerebral vasospasm. Despite its reported safety profile, its use is not free of side effects. Milrinone-associated cardiomyopathy and arrhythmia can occur in patients with cerebral vasospasm. CASE DESCRIPTION This is a retrospective chart review of a patient who presented with aneurysmal subarachnoid hemorrhage and developed clinical vasospasm twice over a period of 2 weeks. Sustained intravenous milrinone infusion was used in association with norepinephrine infusion during this period. The patient developed R-on-T triggered torsades de pointes and cardiogenic shock requiring resuscitation. Follow-up echocardiogram showed decreased ejection fraction from 64% to 43% consistent with cardiac remodeling. Systemic complications such as cardiotoxicity and arrhythmias with the use of intravenous milrinone can be seen particularly when used in combination with catecholamines. CONCLUSIONS With increased combined milrinone and catecholamine use for the treatment of cerebral vasospasm, physicians should be aware of the potential cardiac complications of these agents. Close monitoring with daily electrocardiograms may be helpful to detect changes that suggest cardiotoxicity. If changes are noted, an echocardiogram and cardiology consultation may be warranted.

Abstract
Objective The cause of severe clinical vasospasm after aneurysmal subarachnoid hemorrhage remains unknown, despite extensive research over the past 30 years. However, the intra-arterial administration of vasodilating agents and balloon angioplasty have been successfully used in severe refractory cerebral vasospasm. Materials and Methods We retrospectively analyzed the data of 233 patients admitted to our institute with aneurysmal subarachnoid hemorrhage (SAH) over the past 3 years. Results Of these, 27 (10.6%) developed severe symptomatic vasospasm, requiring endovascular therapy. Vasospasm occurred at an average of 5.3 days after SAH. A total of 46 endovascular procedures were performed in 27 patients. Endovascular therapy was performed once in 18 (66.7%) patients, 2 times in 4 (14.8%) patients, 3 or more times in 5 (18.5%) patients. Intra-arterial vasodilating agents were used in 44 procedures (27 with nimodipine infusion, 17 with nicardipine infusion). Balloon angioplasty was performed in only 2 (7.4%) patients. The Average nimodipine infusion volume was 2.47 mg, and nicardipine was 3.78 mg. Most patients recovered after the initial emergency room visit. Two patients (7.4%) worsened, but there were no deaths. Conclusion With advances in endovascular techniques, administration of vasodilating agents and balloon angioplasty reduces the morbidity and mortality of vasospasm after aneurysmal SAH.

Abstract
The term vasospasm is commonly used to describe constriction of cerebral blood vessels after subarachnoid hemorrhage which results in the restriction of blood flow and ischemia in affected portions of the brain. The pathophysiological changes that underlie vascular constriction after subarachnoid hemorrhage include changes within the vessel walls themselves, alteration of the levels of several vasoactive substances, and broader pathological conditions such as immune responses, inflammation, and oxidative damage. In this review, we summarize the current state of knowledge concerning the processes that occur in cerebral blood vessels after subarachnoid hemorrhage and how they may be involved in the development of vasospasm. We also propose that, rather than merely vasospasm, the multitude of vascular effects occurring after subarachnoid hemorrhage can be best described as a post-subarachnoid hemorrhage vasculopathy.

Abstract
Cerebral vasospasm causes delayed ischemic neurologic deficits after aneurysmal subarachnoid hemorrhage. This is a well-established clinical entity with significant associated morbidity and mortality. The underlying patholphysiology is highly complex and poorly understood. Large-vessel vasospasm, autoregulatory dysfunction, inflammation, genetic predispositions, microcirculatory failure, and spreading cortical depolarization are aspects of delayed neurologic deterioration that have been described in the literature. This article presents a perspective on cerebral vasospasm, as guided by the literature to date, specifically examining the mechanism, diagnosis, and treatment of cerebral vasospasm.

Abstract
Objective Outcome after aneurysmal subarachnoid hemorrhage (SAH) depends critically on delayed cerebral ischemia (DCI) – a process driven primarily by vascular events including cerebral vasospasm, microvessel thrombosis, and microvascular dysfunction. This study sought to determine the impact of postconditioning – the phenomenon whereby endogenous protection against severe injury is enhanced by subsequent exposure to a mild stressor – on SAH-induced DCI. Methods Adult male C57BL/6 mice were subjected to sham, SAH, or SAH plus isoflurane postconditioning. Neurological outcome was assessed daily via sensorimotor scoring. Contributors to DCI including cerebral vasospasm, microvessel thrombosis, and microvascular dysfunction were measured 3 days later. Isoflurane-induced changes in hypoxia-inducible factor 1alpha (HIF-1α)-dependent genes were assessed via quantitative polymerase chain reaction. HIF-1α was inhibited pharmacologically via 2-methoxyestradiol (2ME2) or genetically via endothelial cell HIF-1α-null mice (EC-HIF-1α-null). All experiments were performed in a randomized and blinded fashion. Results Isoflurane postconditioning initiated at clinically relevant time points after SAH significantly reduced cerebral vasospasm, microvessel thrombosis, microvascular dysfunction, and neurological deficits in wild-type (WT) mice. Isoflurane modulated HIF-1α-dependent genes – changes that were abolished in 2ME2-treated WT mice and EC-HIF-1α-null mice. Isoflurane-induced DCI protection was attenuated in 2ME2-treated WT mice and EC-HIF-1α-null mice. Interpretation Isoflurane postconditioning provides strong HIF-1α-mediated macro- and microvascular protection in SAH, leading to improved neurological outcome. These results implicate cerebral vessels as a key target for the brain protection afforded by isoflurane postconditioning, and HIF-1α as a critical mediator of this vascular protection. They also identify isoflurane postconditioning as a promising novel therapeutic for SAH.

Abstract
UNLABELLED Severe angiographic vasospasm (aVSP) is a risk factor for infarction following subarachnoid haemorrhage and infarction is strongly associated with poor outcome. We present the clinico-radiological results of cohort with severe aVSP who underwent a program of angiographic surveillance and sustained endovascular treatment using multiple verapamil infusions and/or transluminal balloon angioplasty (TBA). METHODS This was a dual-centre retrospective observational study. Angiographic screening for vasospasm was undertaken at days 5-7 post-ictus. Treatment was instituted principally on the basis of radiographic findings. The rate of infarction was evaluated on follow-up CT. Clinical outcome was assessed using the modified Rankin Scale (mRS). RESULTS Fifty-seven WFNS grades 1-5 patients were studied. The mean number of procedures/patient was 6, range 2-13. Mean verapamil dose administered to the ICA was 14 mg and VA was 12 mg. Thirty-one patients underwent TBA (52.6%). The rate of proximal vessel infarction was 3/45 (6.7%) for patients presenting <72 hours. Rates of favourable outcome (mRS 0-2) were 16/19 (84.2%) for WFNS grades 1-2, 12/19 (63.2%) for grades 3-4 and 5/19 (26.3%) for grade 5 patients. Delayed presentation >72 hours was the only factor on multivariate analysis to significantly predict aVSP-infarction [OR19.3 (3.2-116.6) P=0.0012]. Large aVSP-infarction [OR19.0 (1.7-216.4) 0.0179] and poor WFNS grade [OR 6.6 (1.3-33.9) P = 0.0233] were significant predictors of poor outcome on multivariate analysis. CONCLUSION This approach may result in low rates of aVSP-infarction and encouraging rates of favourable outcome when compared to literature benchmarks. Delayed presentation, however, predicts infarction and large infarct and poor initial grade significantly influence functional outcome.

Abstract
The use of balloons in the field of neurosurgery is currently an essential part of our clinical practice. The field has evolved over the last 40 years since Serbinenko used balloons to test the feasibility of occluding cervical vessels for intracranial pathologies. Since that time, indications have expanded to include sacrificing cervical and intracranial vessels with detachable balloons, supporting the coil mass in wide-necked aneurysms (balloon remodeling technique), and performing intracranial and cervical angioplasty for atherosclerotic disease, as well as an adjunct to treat arteriovenous malformations. With the rapid expansion of endovascular technologies, it appears that the indications and uses for balloons will continue to expand. In this article, we review the history of balloons, the initial applications, the types of balloons available, and the current applications available for endovascular neurosurgeons.

Abstract
OBJECTIVES Cerebral vasospasm is one of the leading causes of morbi-mortality following aneurysmal subarachnoid hemorrhage. The aim of this article is to discuss the current status of vasospasm therapy with emphasis on endovascular treatment. METHODS A comprehensive review of the literature obtained by a PubMed search. The most relevant articles related to medical, endovascular and alternative therapies were selected for discussion. RESULTS Current accepted medical options include the oral nimodipine and 'triple-H' therapy (hypertension, hypervolemia and hemodilution). Nimodipine remains the only modality proven to reduce the incidence of infarction. Although widely used, 'triple-H' therapy has not been demonstrated to significantly change overall outcome after cerebral vasospasm. Indeed, both induced hypervolemia and hemodilution may have deleterious effects, and more recent physiologic data favor normovolemia with induced hypertension or optimization of cardiac output. Endovascular options include percutaneous transluminal balloon angioplasty (PTA) and intra-arterial (IA) infusion of vasodilators. Multiple case reports and case series have been encountered in the literature using different drug regimens with diverse mechanisms of action. Compared with PTA, IA drug infusion has the advantages of distal penetration and a better safety profile. Its main disadvantages are the more frequent need for repeat treatments and its systemic hemodynamic repercussions. Alternative options using intraventricular/cisternal drug therapy and flow augmentation strategies have also shown possible benefits; however, their use is not yet as well established. CONCLUSION Blood pressure or cardiac output optimization should be the mainstay of hyperdynamic therapy. Endovascular treatment appears to have a positive impact on neurological outcome compared with the natural history of the disease. The role of intraventricular therapy and flow augmentation strategies in association with medical and endovascular treatment may, in the future, play a growing role in the management of patients with severe refractory vasospasm.

Abstract
Vasospasm has been a long known source of delayed morbidity and mortality in aneurysmal subarachnoid hemorrhage patients. Delayed ischemic neurologic deficits associated with vasospasm may account for as high as 50% of the deaths in patients who survive the initial period after aneurysm rupture and its treatment. The diagnosis and treatment of vasospasm has still been met with some controversy. It is clear that subarachnoid hemorrhage is best cared for in tertiary care centers with modern resources and access to cerebral angiography. Ultimately, a high degree of suspicion for vasospasm must be kept during ICU care, and any signs or symptoms must be investigated and treated immediately to avoid permanent stroke and neurologic deficit. Treatment for vasospasm can occur through both ICU intervention and endovascular administration of intra-arterial vasodilators and balloon angioplasty. The best outcomes are often attained when these methods are used in conjunction. The following article reviews the literature on cerebral vasospasm and its treatment and provides the authors’ approach to treatment of these patients.

Abstract
OBJECTIVE Following aneurysmal subarachnoid hemorrhage, cerebral vasospasm/delayed cerebral ischemia accounts for significant morbidity and mortality. In this paper we provide the first glimpse of actual practice in the management of cerebral vasospasm in the USA. METHODS All active members of the Joint American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) Cerebrovascular Section were emailed the survey. The responses were collected anonymously. RESULTS The response rate for this survey was 44% (177 responses/400 total members). Non-responders were characterized by the fact that multiple responders were not obtained from practices that had multiple providers with uniform practice. Both high-volume and low-volume centers were equally represented. Optimizing medical management is first-line treatment in practice. Although there is some variability regarding screening methods, the greatest variability occurs with regard to the choice of intra-arterial treatment drug and dose. There is also considerable variability in the perceived effectiveness of endovascular treatment for vasospasm. CONCLUSIONS In this preliminary glimpse of actual cerebral vasospasm management practice in the USA, two salient points emerge: (1) there is considerable variability in intra-arterial therapies for vasospasm; and (2) there are major differences in the perceived effectiveness of these therapies. Standardization of intra-arterial therapies may contribute to improved outcomes. A prospective randomized trial evaluating endovascular treatment for cerebral vasospasm is needed.

Abstract
OBJECTIVE To retrospectively assess the safety and efficacy of endovascular treatment of cerebral vasospasm with different modalities and assess predictors of outcome. METHODS Endovascular treatment was indicated in the event of neurological deterioration refractory to medical therapy. Data were collected for 116 patients treated at our institution. RESULTS Vasospasm was treated with balloon angioplasty in 52.6%, intra-arterial nicardipine infusion in 19.8%, or both in 27.6%. Angiographic vasospasm was reversed in all but 4 (96.6%) patients. The complication rate was 0.9%. Twenty patients (17.2%) had incipient pre-procedure hypodensities; 3 (15%) hypodensities were reversed and neurological improvement occurred in 60% of these patients. Retreatment was required in 22 (19%) patients. Higher Hunt and Hess grades and treatment with nicardipine alone predicted retreatment. Neurological improvement was noted in 82%. Male gender, pre-procedure hypodensities, and posterior communicating artery aneurysm location negatively predicted neurological recovery. Favorable outcomes were noted in 73%. Higher Hunt and Hess grades, pre-procedure hypodensities, posterior circulation aneurysms, and no neurological recovery predicted poor outcome. CONCLUSION Endovascular therapy for vasospasm has an excellent safety-efficacy profile. Balloon angioplasty and nicardipine are equally effective but effects of nicardipine are less durable. Patients with incipient pre-procedure hypodensities benefit from endovascular intervention and should probably not be excluded from treatment.

Abstract
PURPOSE Cerebral vasospasm (CVS) is a major complication after subarachnoid hemorrhage (SAH) induced by the rupture of intracranial aneurysms. The aim of the present study was to investigate the effect and mechanism of cervical sympathetic block on cerebral vasospasm of the rabbits after SAH. METHODS After successful modeling of cervical sympathetic block, 18 healthy male white rabbits were randomly divided into three groups (n=6), ie, sham operation group (Group A), SAH group (Group B) and SAH with cervical sympathetic block group (Group C). Models of delayed CVS were established by puncturing cisterna magna twice with an injection of autologous arterial blood in Groups B and C. A sham injection of blood through cisterna magna was made in Group A. 0.5 ml saline was injected each time through a catheter for cervical sympathetic block after the first injection of blood three times a day for 3 d in Group B (bilateral alternating). 0.5 ml of 0.25% bupivacaine was injected each time through a catheter for cervical sympathetic block after the first injection of blood three times a day for 7 d in Group B. 2 ml venous blood and cerebrospinal fluid were obtained before (T1), 30 min (T2) and 7 d (T3) after the first injection of blood, respectively, and conserved in a low temperature refrigerator. Basilar artery value at T1, T2 and T3 was measured via cerebral angiography. The degree of damage to nervous system at T1 and T3 was recorded. RESULTS There was no significant difference in diameter of basilar artery at T1 among three groups. The diameters of basilar artery at T2 and T3 of Groups B and C were all smaller than that in Group A, which was smaller than Group C, with a significant difference. There was no significant difference in NO and NOS in plasma and cerebrospinal fluid among three groups. The NO and NOS contents at T2 and T3 of Groups B and C were all lower than Group A; Group C was higher than Group B, with a significant difference. The nerve function at T3 of Groups B and C were all lower than Group A and that of Group C higher than Group B, with a significant difference. CONCLUSION Cervical sympathetic block can relieve cerebral vasospasm after subarachnoid hemorrhage and increase NO content and NOS activity in plasma and cerebrospinal fluid to promote neural functional recovery.

Abstract
BACKGROUND Cerebral vasospasm (VSP) is a major cause of morbidity and mortality associated with subarachnoid hemorrhage. The current endovascular paradigm for VSP refractory to medical therapy is to perform angioplasty for proximal vessel VSP and vasodilator infusion for distal vessel VSP. OBJECTIVE To report our experience with a large series of balloon angioplasty for distal VSP refractory to medical therapy in patients with aneurysmal subarachnoid hemorrhage. METHODS This was a retrospective series of 32 patients with subarachnoid hemorrhage and symptomatic VSP refractory to medical therapy who were treated with balloon angioplasty for distal vessel VSP. Immediate angiographic results, procedure-related complications, and clinical outcomes were assessed. RESULTS From September 2001 to January 2010, 32 patients with symptomatic VSP refractory to medical therapy underwent angioplasty for distal arterial VSP. There were 26 women (81.3%); patients were 29 to 67 years of age. A total of 175 vessels were angioplastied (95 proximal and 80 distal). The only complication was rupture of an incompletely clipped aneurysm that was treated by immediate coiling and did not result in any clinical worsening. Repeated treatment was needed for 6 arteries (6 of 80, 7.5%). There were no procedure-related symptomatic complications. Good outcomes (modified Rankin Scale score ≤ 2) were observed in 23 of 28 patients (82.1%) with follow-up. CONCLUSION Balloon angioplasty for distal VSP is safe and effective and decreases the need for repeated intraarterial treatments seen with infusion of vasodilator.

Abstract
OBJECT As part of a project to devise evidence-based safety interventions for specialty surgery, we sought to review current evidence concerning the frequency of adverse events in open cerebrovascular neurosurgery and the state of knowledge regarding methods for their reduction. This review represents part of a series of papers written to consolidate information about these events and preventive measures as part of an ongoing effort to ascertain the utility of devising system-wide policies and safety tools to improve neurosurgical practice. METHODS The authors performed a PubMed search using search terms "cerebral aneurysm", "cerebral arteriovenous malformation", "intracerebral hemorrhage", "intracranial hemorrhage", "subarachnoid hemorrhage", and "complications" or "adverse events." Only papers that specifically discussed the relevant complication rates were included. Papers were chosen to be included to maximize the range of rates of occurrence for the reported adverse events. RESULTS The review revealed hemorrhage-related hyperglycemia (incidence rates ranging from 27% to 71%) and cerebral salt-wasting syndromes (34%-57%) to be the most common perioperative adverse events related to subarachnoid hemorrhage (SAH). Next in terms of frequency was new cerebral infarction associated with SAH, with a rate estimated at 40%. Many techniques are advocated for use during surgery to minimize risk of this development, including intraoperative neurophysiological monitoring, but are not universally used due to surgeon preference and variable availability of appropriate staffing and equipment. The comparative effectiveness of using or omitting monitoring technologies has not been evaluated. The incidence of perioperative seizure related to vascular neurosurgery is unknown, but reported seizure rates from observational studies range from 4% to 42%. There are no standard guidelines for the use of seizure prophylaxis in these patients, and there remains a need for prospective studies to support such guidelines. Intraoperative rupture occurs at a rate of 7% to 35% and depends on aneurysm location and morphology, history of rupture, surgical technique, and surgeon experience. Preventive strategies include temporary vascular clipping. Technical adverse events directly involving application of the aneurysm clip include incomplete aneurysm obliteration and parent vessel occlusion. The rates of these events range from 5% to 18% for incomplete obliteration and 3% to 12% for major vessel occlusion. Intraoperative angiography is widely used to confirm clip placement; adjuncts include indocyanine green video angiography and microvascular Doppler ultrasonography. Use of these technologies varies by institution. DISCUSSION A significant proportion of these complications may be avoidable through development and testing of standardized protocols to incorporate monitoring technologies and specific technical practices, teamwork and communication, and concentrated volume and specialization. Collaborative monitoring and evaluation of such protocols are likely necessary for the advancement of open cerebrovascular neurosurgical quality.

Abstract
Subarachnoid hemorrhage (SAH) is a devastating cerebrovascular disease. Outcome after SAH is mainly determined by the initial severity of the hemorrhage. Neuroimaging, in particular computed tomography, and aneurysm repair techniques, such as coiling and clipping, as well as neurocritical care management, have improved during the last few years. The management of a patient with SAH should have an interdisciplinary approach with case discussions between the neurointensivist, interventionalist and the neurosurgeon. The patient should be treated in a specialized neurointensive care unit of a center with sufficient SAH case volume. Poor-grade patients can be observed for complications and delayed cerebral ischemia through continuous monitoring techniques in addition to transcranial Doppler ultrasonography such as continuous electroencephalography, brain tissue oxygenation, cerebral metabolism, cerebral blood flow and serial vascular imaging. Neurocritical care should focus on neuromonitoring for delayed cerebral ischemia, management of hydrocephalus, seizures and intracranial hypertension, as well as of medical complications such as hyperglycemia, fever and anemia.

Abstract
Posthemorrhagic cerebral vasospasm (PHCV) is a common problem and a significant cause of mortality and permanent disability following aneurysmal subarachnoid hemorrhage. While medical therapy remains the mainstay of prevention against PHCV and the first-line treatment for symptomatic patients, endovascular options should not be delayed in medically refractory cases. Although both transluminal balloon angioplasty (TBA) and intra-arterial vasodilator therapy (IAVT) can be effective in relieving proximal symptomatic PHCV, only IAVT is a viable treatment option for distal vasospasm. The main advantage of TBA is its long-lasting therapeutic effect and the very low rate of retreatment. However, its use has been associated with a significant risk of serious complications, particularly vessel rupture and reperfusion hemorrhage. Conversely, IAVT is generally considered an effective and low-risk procedure, despite the transient nature of its therapeutic effects and the risk of intracranial hypertension associated with its use. Moreover, newer vasodilator agents appear to have a longer duration of action and a much better safety profile than papaverine, which is rarely used in current clinical practice. Although endovascular treatment of PHCV has been reported to be effective in clinical series, whether it ultimately improves patient outcomes has yet to be demonstrated in a randomized controlled trial.

Abstract
We have previously shown that the clinical utility of transcranial Doppler (TCD) ultrasound monitoring for vasospasm in patients with aneurysmal subarachnoid haemorrhage, as performed by untrained operators in a busy neurosurgical unit, is questionable, despite the recommendations for its use in the literature. We determined if formal training improved the utility of TCD. Twelve untrained operators and one trained operator performed a total of 206 TCD examinations. There was poor agreement of results between trained and untrained operators. For the left middle cerebral artery (MCA), right MCA, left anterior cerebral artery (ACA) and right ACA, the blood flow velocities (BFV) recorded by the trained operator were greater than those recorded by the untrained operators by a mean (95% confidence interval) of 27.7 (25.0-30.4), 24.3 (21.4-27.1), 28.2 (25.6-30.9) and 28.1 (24.9-31.1) cm/s, respectively (p<0.001 for all vessels). Greater sensitivity was observed in TCD measurements from the trained operator (100%) compared to untrained operators (40%). To improve the utility of TCD, operators should be provided with training or a professional sonographer employed.

Abstract
Cerebral vasospasm and delayed cerebral ischemia account for significant morbidity and mortality after aneurysmal subarachnoid hemorrhage. While most patients are managed with triple-H therapy, endovascular treatments have been used when triple-H treatment cannot be used or is ineffective. An electronic literature search was conducted to identify English language articles published through October 2010 that addressed endovascular management of vasospasm. A total of 49 articles were identified, addressing endovascular treatment timing, intra-arterial treatments, and balloon angioplasty. Most of the available studies investigated intra-arterial papaverine or balloon angioplasty. Both have generally been shown to successfully treat vasospasm and improve neurological condition, with no clear benefit from one treatment compared with another. There are reports of complications with both therapies including vessel rupture during angioplasty, intracranial hypertension, and possible neurotoxicity associated with papaverine. Limited data are available evaluating nicardipine or verapamil, with positive benefits reported with nicardipine and inconsistent benefits with verapamil.

Abstract
Object
The goal of this study was to demonstrate feasibility and evaluate technical aspects of early endovascular access through extracranial-intracranial (EC-IC) bypass grafts.
Methods
Patients undergoing endovascular interventions through the graft in the acute postoperative period following EC-IC bypass are presented. Results, complications, and technical nuances are reviewed.
Results
Fourteen endovascular procedures were performed in 5 patients after EC-IC bypass for ruptured aneurysms in 4 patients and posterior circulation ischemia in 1 patient. In 2 patients, a saphenous vein graft (SVG) was used to bypass the common carotid artery (CCA) to the middle cerebral artery (MCA). One patient underwent a superficial temporal artery (STA)–MCA bypass, and in 2 other patients the STA stump was connected to the intracranial circulation via an interposition SVG. The interval from surgery to endovascular intervention spanned 2–18 days; the indication was intracranial vasospasm in all patients. One case involved angioplasty of the proximal anastomosis on postoperative Day 14. All other interventions entailed proximal access through the bypass conduit for intraarterial infusion of vasodilators. Significant vasospasm of the STA itself was encountered in 2 patients during endovascular manipulation, and it was treated with intraarterial nitroglycerin. There were no cases of anastomotic disruption.
Conclusions
Endovascular catheterization and intervention involving a recent EC-IC bypass is feasible. The main limitation in this series was catheter-induced vasospasm involving the STA. A vein graft may be the more appropriate option in patients with subarachnoid hemorrhage who may require subsequent endovascular intervention for vasospasm.

Abstract
Abstract
BACKGROUND:
Cerebral vasospasm is a major cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage. Nicardipine has previously been used to treat vasospasm through superselective intracranial microcatheter injections.
OBJECTIVE:
To evaluate a simple method of treatment of vasospasm with slow infusion of nicardipine from a cervical catheter.
METHODS:
Twenty-seven patients with symptomatic vasospasm were treated over 4 years with cervical catheter infusions. Nicardipine was infused at 20 mg/h for 30 to 60 minutes. Angioplasty was used in severe cases at the operator's discretion. Outcome at discharge and follow-up was evaluated with Glasgow Outcome Scale.
RESULTS:
Twenty-seven patients (17 women, 12 men) received intra-arterial therapy for vasospasm. Vasospasm treatment was done at a mean post-hemorrhage date of 7.2 days (range, 4-15 days). They underwent 48 sessions of treatment (mean, 1.8 per patient) in 72 separate arterial territories. Twelve patients underwent multiple treatments. The mean dose used per session was 19.2 mg (range, 5-50 mg). Four patients underwent angioplasty for severe vasospasm. Twenty-two patients (81.5%) had clinical improvement after the infusion. Angiographic improvement was seen in 86.1% of the vessels analyzed, which had moderate or severe spasm before infusion. Overall, 17 patients (62.9%) had good outcome (Glasgow Outcome Scale score, 4 and 5) at discharge, 11 had poor outcome, and 1 patient died. Follow-up was available in 19 patients, and 18 were doing well (Glasgow Outcome Scale score, 4 and 5).
CONCLUSION:
Intra-arterial nicardipine is an effective and safe treatment for cerebral vasospasm. In most patients, infusion can be performed from the cervical catheter, with microcatheter infusion and angioplasty reserved for the more severe and resistant cases.

Abstract
INTRODUCTION Postpartum cerebral angiopathy is one of the many neurological complications seen during pregnancy and the postpartum period. Management of these patients consists of optimal blood pressure control, and general supportive critical care. We present a case of diffuse cerebral vasospasm, which improved with intra-arterial nicardipine. This brief report addresses the utility of interventional management in cases of postpartum cerebral angiopathy. CASE REPORT A 28-year-old female presented 1 week after cesarean delivery with altered mental status, endotracheal intubation for airway protection, thrombocytopenia, and hypofibrinogenemia. Cerebral angiogram revealed anterior and posterior circulation vasospasm, which responded to repeated selective intra-arterial injections of nicardipine. This treatment coupled with optimal blood pressure control resulted in complete recovery. DISCUSSION Our case report highlights the importance of cerebral angiography for the diagnosis and treatment of patients with postpartum cerebral angiopathy. Although nicardipine is used in patients with aneurysmal subarachnoid hemorrhage for the treatment of cerebral vasospasm, this agent has the potential to be used in patients with cerebral vasospasm due to other etiologies. SUMMARY Intra-arterial nicardipine is one of the therapeutic measures available to physicians in the management of patients with cerebral vasospasm. In patients with postpartum cerebral angiopathy, early cerebral angiography should be considered to quantify and treat cerebral vasospasm with either angioplasty or selective intra-arterial injections of nicardipine.

Abstract
Abstract
BACKGROUND:
Studies attempting to establish the safety and efficacy of standard and high-dose intra-arterial infusions of calcium channel blockers for treatment of cerebral vasospasm have focused on hemodynamic changes during the angiographic procedure.
OBJECTIVE:
To evaluate longer-term drug effects over the hours following infusion and the effects on brain tissue oxygen tension or cerebral metabolism.
METHODS:
We studied 11 patients with poor-grade aneurysmal subarachnoid hemorrhages who underwent multimodality brain monitoring and angiography with infusion of high-dose intra-arterial verapamil (≥15 mg total dose). Hourly intracerebral microdialysis measurements and continuously recorded mean arterial pressure (MAP), intracranial pressure (ICP), cerebral perfusion pressure (CPP), and Pbto2 were analyzed for 6 hours before and 12 hours following treatment.
RESULTS:
A median dose of 23 mg (range, 15-55 mg) of intra-arterial verapamil was given. Compared with baseline values, reductions in CPP and MAP were maximal at 3 hours postangiography (from 105 ± 13 mm Hg to 95 ± 15 mm Hg and from 116 ± 12 mm Hg to 106 ± 16 mm Hg, P < .01) and persisted for up to 6 hours (P < .04); increases in vasopressor therapy were required in 8 procedures (53%). ICP significantly increased during the first 3 hours post angiography (P < .03). Brain glucose increased by 33% by hour 9 (P < .001). There were no significant changes in Pbto2 or the lactate/pyruvate ratio.
CONCLUSION:
High-dose intra-arterial verapamil causes increases in ICP and reductions in CPP, followed by an increase in brain glucose levels, without altering brain oxygen tension or oxidative metabolism. Patients undergoing high-dose intra-arterial verapamil therapy warrant close hemodynamic and ICP monitoring for at least 12 hours following treatment.

Abstract
BACKGROUND AND PURPOSE CV following aneurysmal SAH is a significant cause of morbidity and mortality. We review our experiences using PTA and IA verapamil infusion for treating medically refractory cases. MATERIALS AND METHODS We performed a retrospective review of patients with SAH admitted from July 2003 to January 2008. RESULTS Of 546 patients admitted within 72 hours of symptom onset, 231 patients (42%) developed symptomatic CV and 189 patients (35%) required endovascular therapy. A total of 346 endovascular sessions were performed consisting of 1 single angioplasty, 286 IA verapamil infusions, and 59 combined treatments. PTA was performed on 151 vessel segments, and IA verapamil was infused in 720 vessel segments. IA verapamil doses ranged from 2.0 to 30.0 mg per vessel segment and from 3.0 to 55.0 mg per treatment session. Repeat treatments were necessary in 102 patients (54%) for persistent, recurrent, or worsening CV. There were 6 treatment-related complications, of which 2 resulted in clinical worsening. No deaths were attributable to endovascular therapy. At follow-up, 115 patients (61%) had a good outcome and 55 patients (29%) had a poor outcome. Sixteen patients died from causes related to SAH, while 3 died from other medical complications. CONCLUSIONS Endovascular treatments are an integral part of managing patients with medically refractory CV. In our experience, PTA and IA verapamil are safe, with a low complication rate, but further studies are required to determine appropriate patient selection and treatment efficacy.

Abstract
Retroperitoneal hematoma (RH) due to radiologic intervention for an intracranial lesion is relatively rare, difficult to diagnose, and can be life-threatening. We report a case of RH that developed in a patient on anticoagulant therapy following endovascular coiling of a ruptured anterior communicating artery (AcoA) aneurysm. An 82-year-old man presented with a 12-day history of headache. Computed tomography (CT) on admission demonstrated slight subarachnoid hemorrhage, and left carotid angiography revealed an AcoA aneurysm. The next day, the aneurysm was occluded with coils via the femoral approach under general anesthesia. The patient received a bolus of 5,000 units of heparin immediately following the procedure, and an infusion rate of 10,000 units/day was initiated. The patient gradually became hypotensive 25 hours after coiling. Abdominal CT showed a huge, high-density soft-tissue mass filling the right side of the retroperitoneum space. The patient eventually died of multiple organ failure five days after coiling. RH after interventional radiology for neurological disease is relatively rare and can be difficult to diagnose if consciousness is disturbed. This case demonstrates the importance of performing routine physical examinations, sequentially measuring the hematocrit and closely monitoring systemic blood pressures following interventional radiologic procedures in patients with abnormal mental status.

Abstract
The incidence of convulsion and associated factors were retrospectively analyzed in 23 patients with symptomatic cerebral vasospasm following subarachnoid hemorrhage (SAH) who underwent a total of 31 intra-arterial infusion of fasudil hydrochloride (IAFH) procedures in 49 vessels. Fasudil hydrochloride was administered by superselective infusion via a microcatheter positioned at the proximal portion of the affected artery. Thirteen procedures were performed by manually controlled infusion of 30-75 mg fasudil hydrochloride (1.2-3.75 mg/ml) for approximately 10 minutes. Eighteen procedures were performed by continuous infusion of 60 mg fasudil hydrochloride (1.2 mg/ml) by infusion pump at a constant rate of 3 mg/min. Neurological improvement was observed after 18 of 22 procedures in patients with neurological deterioration due to vasospasm. Convulsion during IAFH developed in 4 patients, all treated by manual infusion (p < 0.05). The manual infusion method (p < 0.05) and infusion rate greater than 3 mg/min (p < 0.01) were significantly associated with the incidence of convulsion during IAFH. IAFH was effective for treating cerebral vasospasm following aneurysmal SAH. IAFH at a constant rate of 3 mg/min delivered by infusion pump improved the symptoms of cerebral vasospasm and prevented convulsions during IAFH.

Abstract
OBJECTIVE Hypertensive hypervolemic therapy is widely used to treat symptomatic vasospasm after subarachnoid hemorrhage. Few data exist to support a relationship between early clinical response and mortality or functional outcome. METHODS In a prospective cohort of 580 subarachnoid hemorrhage patients, we studied 95 patients with acute symptomatic vasospasm who received stepwise volume expansion with crystalloid and/or 5% albumin solution followed by intravenous pressors to maintain systolic blood pressure between 180 and 220 mm Hg. We separately assessed the effects of volume expansion and induced hypertension on the neurological examination during the first 2 hours of each intervention. We used multivariate logistic regression analysis to calculate adjusted odds ratios assessing the relationship between clinical response to hypertensive hypervolemic therapy and 3-month outcome, as measured by the modified Rankin Scale. RESULTS Of 95 patients with symptomatic vasospasm, volume expansion was used in 94% (n = 89), of whom 43% had a clinical response; 85% of the patients (n = 81) received pressors, of whom 68% responded. Early clinical improvement attributable to either volume expansion or pressors was not related to the development of infarction on computed tomography, but response to either modality within 2 hours was independently protective against death (adjusted odds ratio, 0.03; P < 0.05) and death-or-severe-disability (modified Rankin Scale score, 4-6; adjusted odds ratio, 0.1; P < 0.05) after adjusting for age, Hunt-Hess grade, angioplasty, and aneurysm size. CONCLUSION Subarachnoid hemorrhage patients with symptomatic vasospasm who fail to demonstrate early clinical improvement in response to volume or pressor therapy are at high risk for death or disability. Urgent endovascular intervention in this high-risk patient cohort may be justified.

Abstract
OBJECTIVE Experimental work suggests a neuroprotective role for magnesium sulfate in aneurysmal subarachnoid hemorrhage. We retrospectively review the incidence of clinically relevant vasospasm in patients treated or not with continuous magnesium infusion after onset of subarachnoid hemorrhage. METHODS All patient records in Albany Medical Center with the diagnosis of SAH between January 1999 and June 2004 were reviewed. Patients who presented to the emergency department within 72 hours of onset were entered in the study. Patients were defined as in clinical vasospasm if there was an acute neurological change in association with abnormal trancranial Doppler (TCD), CT angiogram (CTA) or digital subtraction angiography (DSA). RESULTS A total of 85 patients were selected. Magnesium sulfate was infused in 43 patients. When compared with patients who did not receive MgSO(4), there was a statistically significant lower incidence of clinical and radiological vasospasm in those who had the continuous infusion of magnesium sulfate (p<0.01). There was no statistically significant difference between patients who were coiled or clipped. CONCLUSION Continuous magnesium sulfate infusion for the management of clinically significant cerebral vasospasm is safe and reduces the incidence of clinically significant cerebral vasospasm. Large, multicenter, controlled studies should be performed in order to determine the true effectiveness of the treatment in a controlled setting.

Abstract
OBJECTIVE Since cerebral vasospasm (CV) was first described nearly half a century ago, significant progress has been made in understanding its underlying pathophysiology and developing treatment modalities. The purpose of this review is to discuss the rationale behind mechanical interventions for CV as well as the efficacy and complications associated with these treatment options. METHODS The authors summarize the pertinent literature on the mechanical treatment of CV, focusing first on balloon angioplasty, second on therapy combined with intra-arterial drug infusion, and concluding by briefly discussing intra-aortic balloon counterpulsation. The epidemiology, pathophysiology, technique, outcome, timing and complications are discussed for each treatment option. RESULTS A review of the relevant medical literature reveals that in the last 20 years, endovascular techniques including transluminal balloon angioplasty, intra-arterial drug infusion and newer experimental strategies have provided an important supplement to the established medical therapy. DISCUSSION Despite these developments, however, CV remains a major contributor to poor outcome following aSAH and continued efforts are necessary to improve and refine endovascular strategies as well as develop new treatment modalities.

Abstract
The authors report a case of restenosis in the bilateral internal carotid arteries (ICAs) following angioplasty for cerebral vasospasm. This 53-year-old woman suffering subarachnoid hemorrhage due to a ruptured posterior communicating artery aneurysm had severe vasospasm and underwent angioplasty of the left and right ICAs and middle cerebral arteries. Two months later, a follow-up CT angiogram revealed bilateral ICA stenoses.
Transluminal angioplasty leads to long-term connective tissue damage in the medial and adventitial layers from the disruption of the arrangement of collagen fibers due to stretching and tearing, resulting in loss of transmission of contractile forces. Furthermore, following endothelial cell denudation and stretching and rupture of internal elastic lamina from angioplasty, reendothelialization of the intimal layer composed of smooth muscle cells may also explain the contractile properties of restenosis. Other factors such as macrophage-induced inflammation and reactive oxygen species accumulation may also contribute to restenosis. This is the second reported case of restenosis following angioplasty to treat vasospasm, although restenosis is a known complication of angioplasty for treatment of atherosclerosis. In addition, this is the first case of restenosis in the bilateral ICAs following angioplasty for vasospasm. This report presents an illustrative case study and reviews the pathophysiology of angioplasty and restenosis.
