Abstract
BACKGROUND Cerebral aneurysm surgery has significant mortality and morbidity rate. Inflammation plays a key role in the pathogenesis of intracranial aneurysms, their rupture, subarachnoid hemorrhage and neurologic complications. Proinflammatory cytokine level in blood and cerebrospinal fluid (CSF) is an indicator of inflammatory response. Cytokines contribute to secondary brain injury and can worsen the outcome of the treatment. Lidocaine is local anesthetic that can be applied in neurosurgery as regional anesthesia of the scalp and as topical anesthesia of the throat before direct laryngoscopy and endotracheal intubation. Besides analgesic, lidocaine has systemic anti-inflammatory and neuroprotective effect.Primary aim of this trial is to determine the influence of local anesthesia with lidocaine on the perioperative levels of pro-inflammatory cytokines interleukin-1β, interleukin-6, and tumor necrosis factor-α in plasma and CSF in cerebral aneurysm patients. METHODS We will conduct prospective randomized clinical trial among patients undergoing craniotomy and cerebral aneurysm clipping surgery in general anesthesia. Patients included in the trial will be randomly assigned to the lidocaine group (Group L) or to the control group (Group C). Patients in Group L, following general anesthesia induction, will receive topical anesthesia of the throat before endotracheal intubation and also regional anesthesia of the scalp before Mayfield frame placement, both done with lidocaine. Patients in Group C will have general anesthesia only without any lidocaine administration. The primary outcomes are concentrations of cytokines interleukin-1β, interleukin-6 and tumor necrosis factor-α in plasma and CSF, measured at specific timepoints perioperatively. Secondary outcome is incidence of major neurological and infectious complications, as well as treatment outcome in both groups. DISCUSSION Results of the trial could provide insight into influence of lidocaine on local and systemic inflammatory response in cerebrovascular surgery, and might improve future anesthesia practice and treatment outcome. TRIAL IS REGISTERED AT CLINICALTRIALS.GOV:: NCT03823482.

Abstract
Diagostic approach to aneurysmal subarachnoid hemorrhage (aSAH) is based on computer tomography (CT) imaging, although a lumbar puncture and subsequent cerebrospinal fluid analysis is sometimes necessary. Identification of the ruptured aneurysm is done using angiography. Despite of modern imaging techniques, diagnostic definition of aSAH is still occasionally challenging. We describe three cases in which the diagnosis of aSAH has been delayed, in spite of positive imaging or lumbar puncture findings.

Abstract
Subarachnoid hemorrhage (SAH) carries a 50% mortality rate. The extravasated erythrocytes that surround the brain contain heme, which, when released from damaged red blood cells, functions as a potent danger molecule that induces sterile tissue injury and organ dysfunction. Free heme is metabolized by heme oxygenase (HO), resulting in the generation of carbon monoxide (CO), a bioactive gas with potent immunomodulatory capabilities. Here, using a murine model of SAH, we demonstrated that expression of the inducible HO isoform (HO-1, encoded by Hmox1) in microglia is necessary to attenuate neuronal cell death, vasospasm, impaired cognitive function, and clearance of cerebral blood burden. Initiation of CO inhalation after SAH rescued the absence of microglial HO-1 and reduced injury by enhancing erythrophagocytosis. Evaluation of correlative human data revealed that patients with SAH have markedly higher HO-1 activity in cerebrospinal fluid (CSF) compared with that in patients with unruptured cerebral aneurysms. Furthermore, cisternal hematoma volume correlated with HO-1 activity and cytokine expression in the CSF of these patients. Collectively, we found that microglial HO-1 and the generation of CO are essential for effective elimination of blood and heme after SAH that otherwise leads to neuronal injury and cognitive dysfunction. Administration of CO may have potential as a therapeutic modality in patients with ruptured cerebral aneurysms.

Abstract
OBJECTIVES To describe the findings in cerebrospinal fluid from patients with acute headache that could distinguish subarachnoid hemorrhage from the effects of a traumatic lumbar puncture. DESIGN A substudy of a prospective multicenter cohort study. SETTING 12 Canadian academic emergency departments, from November 2000 to December 2009. PARTICIPANTS Alert patients aged over 15 with an acute non-traumatic headache who underwent lumbar puncture to rule out subarachnoid hemorrhage. MAIN OUTCOME MEASURE Aneurysmal subarachnoid hemorrhage requiring intervention or resulting in death. RESULTS Of the 1739 patients enrolled, 641 (36.9%) had abnormal results on cerebrospinal fluid analysis with >1 × 10(6)/L red blood cells in the final tube of cerebrospinal fluid and/or xanthochromia in one or more tubes. There were 15 (0.9%) patients with aneurysmal subarachnoid hemorrhage based on abnormal results of a lumbar puncture. The presence of fewer than 2000 × 10(6)/L red blood cells in addition to no xanthochromia excluded the diagnosis of aneurysmal subarachnoid hemorrhage, with a sensitivity of 100% (95% confidence interval 74.7% to 100%) and specificity of 91.2% (88.6% to 93.3%). CONCLUSION No xanthochromia and red blood cell count <2000 × 10(6)/L reasonably excludes the diagnosis of aneurysmal subarachnoid hemorrhage. Most patients with acute headache who meet this cut off will need no further investigations and aneurysmal subarachnoid hemorrhage can be excluded as a cause of their headache.

Abstract
INTRODUCTION Sympathetic activation promotes hemostasis, and subarachnoid hemorrhage (SAH) is associated with pronounced sympathetic activation. This investigation will assess whether catecholaminergic activity relates to venous thrombotic events in patients with acute SAH. METHODS Observational study of consecutive SAH grade 3-5 patients requiring ventriculostomy insertion who did not undergo open surgical treatment of cerebral aneurysm. Cerebrospinal fluid (CSF) samples were obtained within 48 h of hemorrhage for assay of catecholamines, which were related to occurrence of deep venous thrombosis (DVT) and pulmonary embolization (PE). RESULTS Of the 92 subjects, mean age was 57 years, 76% were female, and 57% Caucasian; 11% experienced lower extremity (LE) DVT, 12% developed upper extremity (UE) or LE DVT, and 23% developed any DVT/PE. Mean time to occurrence of UE/LE DVT was 7.8 days (+/-5.9 days), and mean time to development of PE was 8.8 days (+/-5.4 days). In hazards analysis models, independent predictors of LE DVT included neurogenic cardiomyopathy (NC) [HR 4.97 (95%CI 1.32-18.7)], norepinephrine/3,4-dihydroxyphenylglycol ratio (NE/DHPG) [3.81 (2.04-7.14)], NE [5.91 (2.14-16.3)], and dopamine (DA) [2.27 (1.38-3.72)]. Predictors of UE/LE DVT included NC [5.78 (1.70-19.7)], cerebral infarction [4.01 (1.18-13.7)], NE [3.58 (1.40-9.19)], NE/DHPG [3.38 (1.80-6.33)] and DA [2.01 (1.20-3.35)]. Predictors of DVT/PE included Hunt-Hess grade (H/H) [3.02 (1.19-7.66)], NE [2.56 (1.23-5.37)] and 3,4-dihydroxyphenylalanine (DOPA) [3.49 (1.01-12.0)]. CONCLUSIONS In severe SAH, central sympathetic activity and clinical manifestations of (nor)adrenergic activity relate to the development of venous thromboemboli. Catecholamine activation may promote hemostasis, or may represent a biomarker for venous thromboses.

Abstract
Subarachnoid hemorrhage (SAH) is a devastating neurological injury associated with significant patient morbidity and death. Since the first demonstration of cerebral vasospasm nearly 60 years ago, the preponderance of research has focused on strategies to limit arterial narrowing and delayed cerebral ischemia following SAH. However, recent clinical and preclinical data indicate a functional dissociation between cerebral vasospasm and neurological outcome, signaling the need for a paradigm shift in the study of brain injury following SAH. Early brain injury may contribute to poor outcome and early death following SAH. However, elucidation of the complex cellular mechanisms underlying early brain injury remains a major challenge. The advent of modern neuroproteomics has rapidly advanced scientific discovery by allowing proteome-wide screening in an objective, nonbiased manner, providing novel mechanisms of brain physiology and injury. In the context of neurosurgery, proteomic analysis of patient-derived CSF will permit the identification of biomarkers and/or novel drug targets that may not be intuitively linked with any particular disease. In the present report, the authors discuss the utility of neuroproteomics with a focus on the roles for this technology in understanding SAH. The authors also provide data from our laboratory that identifies high-mobility group box protein-1 as a potential biomarker of neurological outcome following SAH in humans.

Abstract
OBJECTIVES To investigate the effect of early aneurysm surgery (<72 h) on outcome in patients with subarachnoid haemorrhage (SAH). MATERIALS AND METHODS We studied two consecutive series of patients with aneurysmal SAH [postponed surgery (PS) cohort, n = 118, 1989-1992: surgery was planned on day 12 and early surgery (ES) cohort, n = 85, 1996-1998: ES was performed only in patients with Glasgow Coma Scale (GCS) >13]. We used multivariable logistic regression analysis to assess outcome at 3 months. RESULTS Favourable outcome (Glasgow Outcome Scale 4 or 5) was similar in both cohorts. Cerebral ischemia occurred significantly more often in the ES cohort. The occurrence of rebleeds was similar in both cohorts. External cerebrospinal fluid (CSF) drainage was performed more often in the ES cohort (51% vs 19%). Patients with cisternal sum score (CSS) of subarachnoid blood <15 on admission [adjusted odds ratio (OR) for favourable outcome: 6.4, 95% confidence interval (CI) 1.0-39.8] and patients with both CSS <15 and GCS > 12 on admission benefited from the strategy including ES (OR 10.5, 95% CI 1.1-99.4). CONCLUSIONS Our results support the widely adopted practice of ES in good-grade SAH patients.

Abstract
OBJECTIVE To determine the sensitivity, specificity, and negative and positive predictive values of cerebrospinal fluid (CSF) xanthochromia for detection of ruptured cerebral aneurysms in patients with thunderclap headache (sudden and severe headache with maximal intensity at onset). PATIENTS AND METHODS We identified patients who presented to our emergency department with symptoms of thunderclap headache between January 1, 1998, and January 1, 2008. Those with normal results on computed tomography (CT) of the head were selected for inclusion in the study. All consenting adult patients had undergone a lumbar puncture procedure for CSF analysis. Xanthochromia was assessed by visual inspection. All patients with a normal CT result were further evaluated by conventional 4-vessel catheter angiography. If no aneurysms were detected in the initial study, the procedure was performed again within 7 to 14 days. All patients were followed up clinically for a mean period of approximately 29 months. RESULTS A total of 152 patients were identified (mean +/- SD age, 44.7+/-15.8 years; 53 men). Cerebrospinal fluid xanthochromia was present in 18 patients (12%), 13 (72%) of whom were ultimately diagnosed as having aneurysmal subarachnoid hemorrhage. A single patient who tested negative for xanthochromia and had a normal CT result was subsequently found to have a ruptured middle cerebral artery aneurysm. The sensitivity, specificity, positive predictive value, and negative predictive value of CSF xanthochromia for detection of cerebral aneurysms were 93%, 95%, 72%, and 99%, respectively. CONCLUSION Although not perfect, visual inspection of CSF in patients with a history suggestive of subarachnoid hemorrhage remains a highly valuable and simple test to detect a recently ruptured aneurysm.

Abstract
BACKGROUND The pathophysiology of ischemic cerebral lesions following aneurysmal subarachnoid hemorrhage (SAH) is poorly understood. There is growing evidence that inflammatory reactions could be involved in the pathogenesis of such delayed occurring ischemic lesions. The aim of this study was to evaluate adhesion molecules with regard to these lesions following SAH. METHODS Serum and cerebrospinal fluid (CSF) samples were taken daily from 15 patients up to day 9 after SAH and evaluated for intercellular adhesion molecule-1 (ICAM-1) and vascular adhesion molecule-1 (VCAM-1). RESULTS CSF and serum samples correlated well during nearly the whole time course (p < 0.0001). A secondary increase in ICAM-1 and VCAM-1 in the serum and CSF correlated with an increase in flow velocity in the transcranial Doppler (p > 0.0001 and p < 0.007) but not to a delayed lesion in the CT scan. CONCLUSION We believe that inflammatory processes are involved in the pathogenesis of cerebral vasospasm but they might only be a part of a multifactorial pathogenesis.

Abstract
The goal of the present study was to determine concentrations of E-selectin in both cerebrospinal fluid (CSF) and serum of patients with aneurysmal subarachnoid hemorrhage (SAH) and to evaluate the correlation between the clinical parameters and E-selectin levels. Both CSF and serum samples obtained from 12 patients with aneurysmal SAH and 8 patients with hydrocephalus (control group) without any other known central nervous system disease were assayed for E-selectin by quantitative enzyme-linked immunosorbent assay and the results were compared between the two groups. Mean levels of soluble forms of E-selectin within the first 3 days and on the 5th and 7th days of SAH were 4.0 +/- 7.9, 2.8 +/- 5.2, and 3.1 +/- 4.9 ng/ml in the patient's CSF, and 33.7 +/- 9.2, 35.1 +/- 7.0, and 35.2 +/- 8.7 ng/ml in serum, respectively. In contrast, mean E-selectin levels were 0.1 +/- 0.2 ng/ml in CSF and 8.7 +/- 5.0 ng/ml in serum of control patients. The difference between groups was statistically significant regarding both CSF and serum E-selectin levels (P < 0.05). Thus, we have demonstrated a marked increase of E-selectin concentration in both CSF and serum of patients with aneurysmal SAH compared with control and suggest that blocking the interaction between E-selectin and vascular endothelium may have a beneficial effect on vasospasms.

Abstract
Cerebral mycotic aneurysms are one of the most serious complications of bacterial endocarditis but the mechanism underlying cerebral aneurysms is unclear. We reported the cytokine levels in a cerebral mycotic aneurysm in a child with Down's syndrome. The patient was a 12-year-old female. She was diagnosed as having Down's syndrome and congenital heart disease consisting of an endocardial cushion defect at birth. She underwent a radical operation at 9 years but mitral valve regurgitation remained. She was hospitalized with high fever, vomiting, loss of activity and gait disturbance. Neurological examination revealed facial palsy and hemiparesis on the left side. Cytokines such as IL-6, TNF-alpha, sTNFR1 and sE-selectin were elevated in blood, and IL-6, TNF-alpha and sTNFR1 in cerebrospinal fluid. T2-weighted MRI disclosed a low intensity area in the right Sylvian sulcus. MR angiography showed an aneurysm of the right middle cerebral artery. We think that cytokines and the formation abnormality of collagen fibers are related to the production of aneurysms.

Abstract
In the examination of a patient with acute headache in which subarachnoid haemorrhage is suspected, a CT scan of the brain should be performed without delay. If the CT scan does not confirm subarachnoid haemorrhage, the next step is a lumbar puncture. This should not take place before twelve hours have elapsed from the start of the headache, so as to allow for the formation of sufficient amounts of bilirubin to be detected in a possible subarachnoid haemorrhage. Bilirubin colours the spinal fluid characteristically yellow and is detectable for at least two weeks following a subarachnoid haemorrhage. Spectrophotometric detection of bilirubin in the spinal fluid is considered more sensitive than visual detection. We present a case in which the spectrophotometric detection of bilirubin in the spinal fluid was the only pathological test result in the examination of a patient with acute headache. The spectrophotometric detection revealed an intracranial aneurysm, for which the patient received subsequent lifesaving surgical treatment. Spectrophotometric examination of spinal fluid has a high sensitivity rate. The test is simple to perform, is not expensive, and is within the scope of most laboratories. We present our method for spectrophotometric investigation of spinal fluid, along with practical advice.

Abstract
Few reports of temporary disruption of the blood-brain barrier (BBB) following neurointerventional procedures, presumably caused by nonionic radiographic contrast medium (CM), exist in the literature. We described such a case in a 72-year-old man presenting with acute subarachnoid hemorrhage, who underwent coil embolization of a ruptured anterior communicating artery complex aneurysm. At the time of his follow-up CT examination, a large amount of iodine was found in the cerebrospinal fluid (CSF). Because of this experience, the iodine concentration in the CSF of five other patients who also underwent an intracranial endovascular procedure was measured. It was concluded that this increased iodine might have been caused by temporary leakage or breakdown of the BBB. Even if the total amount of CM may not be excessive, the disproportionately high concentration injected into a single vascular territory may pose a unique set of variables increasing the risk of BBB disruption.

Abstract
BACKGROUND This study assessed the concentration of rocuronium in the cerebrospinal fluid (CSF) of patients undergoing cerebral aneurysm clipping, and investigated whether the mode of administration (single bolus vs continuous infusion) influenced the CSF concentration. METHODS Twenty patients with subarachnoid haemorrhage were randomly allocated to receive a bolus dose (bolus group), or a bolus followed by a continuous infusion of rocuronium (infusion group) (n=10 for each group). Arterial blood and ventricular CSF were sampled 2 h after the rocuronium bolus. Samples were analysed by liquid chromatography electrospray ionization-tandem mass spectrometry. RESULTS Rocuronium could be detected in all the CSF samples. The mean (range) CSF concentration was 2.2 (0.9-4.6) ng x ml(-1) in the bolus group and 12.4 (2.4-34.6) ng x ml(-1) in the infusion group; P<0.01. CONCLUSIONS This study demonstrated that rocuronium, normally not considered to cross the blood-brain barrier, is regularly found in the CSF of patients undergoing cerebral clipping; continuous infusion of the drug led to higher plasma and CSF concentrations than after a single bolus dose.

Abstract
Cytokines play a key role in mutual influence of the immunological, endocrine and CNS systems. It has been proven that proinflammatory ILs may intensify the cascade of biochemical changes in ischemic brain damage. Vasospasm, which may accompany SAH and often coexists with symptoms of DINDs, is the cause of ischemic changes in the brain. It is thought that immunological mechanisms may be one of the causes of degenerative-productive changes in vessel walls, in delayed vasospasm following SAH, which lead to substantial vasospasm and in consequence too cerebral ischemia. In the randomly selected group of patients, who underwent surgical treatment after aneurysmal SAH, we determined the concentration of IL-1 beta and IL-6 in CSF in the periods between Days 0 to 3; 4 to 7; and 8 to 15 after the occurrence of SAH. The presence and dynamics of development of vasospasm were assessed on the basis of increasing DINDs as well as CT and cerebral angiography. We examined the concentrations of ILs in CSF using radioimmunological methods, applying commercially available tests for their assessment. We found that in the period between 8 and 15 days after SAH, in increasing delayed vasospasm and DINDs, here is a statistically significant increase concentration of IL-1 beta in CSF (105.4 +/- 46.9 pg x ml-1; p<0.005), and no significant changes in patients without vasospasm and neurological deficits. On the other hand, we noted a statistically significant increase concentration of IL-6 in CSF (4802 +/- 1170 ng x ml-1; p<0.05) only in the acute phase after SAH (Days 0-3) in patients in poor clinical condition, in whom delayed vasospasm and cerebral ischemia developed later. This increase of ILs level in CSF is probably related to the intensity of the SAH, and secondarily aggravates the vasospasm and ischemic changes in the brain.

Abstract
BACKGROUND The pathogenesis of cerebral vasospasm is likely to be multifactorial. Exposure of the adventitia of large cerebral arteries to blood breakdown products initiates a cascade of changes in both morphology and vasomotor regulation of the exposed vessels. The role of nitric oxide (NO) in development of cerebral vasospasm process is controversial. Basal cerebral vascular tone requires the continuous release of NO, nevertheless NO is involved in free radical mediated injury of endothelial cell membrane. Concentrations of nitrate/nitrite (stabile endproducts of NO metabolism) were studied in cisternal cerebrospinal fluid (cCSF) in patients suffering from aneurysmal subarachnoid haemorrhage (SAH). METHOD 21 patients suffering from aneurysmal SAH were investigated. Treatment included aneurysm clipping, cisternal drainage of CSF and intravenous nimodipine in all patients as well as tripple H therapy when indicated. TCDS was performed on a daily basis. A mean flow velocity of more than 150 cm/sec and the development a delayed neurological deficit was defined as vasospasm. CSF samples were collected on the day of surgery and for the 7 days following. NO-M (nitrite and nitrate) were measured using a commercially available test kit. FINDINGS 5 of 21 patients developed clinically symptomatic vasospasm. There was a significant difference in NO levels between the groups. Patients with cerebral vasospasm showed significantly higher levels of NO-M in CSF than patients with a uncomplicated follow-up between day 2 and 8. INTERPRETATION Our preliminary results indicate that SAH leads to an increase in NO-M in CSF. This increase of NO-M significantly correlates with the flow velocities in TCDS measurement suggesting that NO plays an important role in the pathogenesis of cerebral vasospasm.

Abstract
BACKGROUND The aim of this paper is to compare the propofol concentration in blood and cerebrospinal fluid (CSF) in patients scheduled for different neurosurgical procedures and anaesthetized using propofol as part of a total intravenous anaesthesia technique. METHODS Thirty-nine patients (ASA I-III) scheduled for elective intracranial procedures, were studied. Propofol was infused initially at 12 mg kg(-1) h(-1) and then reduced in steps to 9 and 6 mg kg(-1) h(-1). During anaesthesia, bolus doses of fentanyl and cis-atracurium were administered as necessary. After tracheal intubation the lungs were ventilated to achieve normocapnia with an oxygen-air mixture (FI(O(2))=0.33). Arterial blood and CSF samples for propofol examination were obtained simultaneously directly after intracranial drainage insertion and measured using high-performance liquid chromatography. The patients were divided into two groups depending on the type of neurosurgery. The Aneurysm group consisted of 13 patients who were surgically treated for ruptured intracranial aneurysm. The Tumour group was composed of 26 patients who were undergoing elective posterior fossa extra-axial tumour removal. RESULTS Blood propofol concentrations in both groups did not differ significantly (P>0.05). The propofol concentration in CSF was 86.62 (SD 37.99) ng ml(-1) in the Aneurysm group and 50.81 (26.10) ng ml(-1) in the Tumour group (P<0.005). CONCLUSIONS Intracranial pathology may influence CSF propofol concentration. However, the observed discrepancies may also result from quantitative differences in CSF composition and from restricted diffusion of the drug in the CSF.

Abstract
BACKGROUND Cerebral vasospasm is a poor resulting outcome of a ruptured cerebral aneurysm; to clarify the mechanism of vasospasm it is important to improve this outcome. C-type natriuretic peptide (CNP) is present in the brain as a cerebral vasodilator; it is also an endothelium-derived relaxing factor produced via cGMP. We speculated that CNP might be an inhibitor of cerebral vasospasm after subarachnoid hemorrhage (SAH). METHODS To clarify the role of CNP in cerebral vasospasm after SAH, we conducted 1 week monitoring of CNP concentrations in the plasma and cerebrospinal fluid (CSF) of 26 patients who had undergone clipping within 24 hours of the occurrence of SAH, and divided them into group A (positive for angiographic spasm) and group B (negative for angiographic spasm). We also examined CNP concentrations in the CSF of patients who were receiving spinal anesthesia for small orthopedic operations, as reference patients. RESULTS The CNP concentration in the CSF on day 1 was higher than in the reference patients and decreased in both test groups, but we did not observe any significant difference between the groups. CNP concentrations in the plasma did not change in either group. CONCLUSIONS CNP concentrations in the CSF were high in the acute phase after SAH, whereas plasma CNP concentrations remained constant. However, our findings did not support our hypothesis because we did not find any relationship between vasospasm and changes in CNP concentrations in the CSF.

Abstract
OBJECTIVE Many patients exhibit cognitive disturbances after aneurysmal subarachnoid hemorrhage (SAH). Structural and functional neuroimaging has failed to demonstrate any correlation with these complaints. This study was performed to investigate whether neuropeptide concentrations in cerebrospinal fluid could be related to cognitive disturbances after SAH. METHODS Lumbar cerebrospinal fluid was obtained, 3 to 6 months after surgery, from 17 patients who experienced good outcomes after aneurysmal SAH. The samples were analyzed for various neuropeptides using radioimmunoassays, and the peptide concentrations were evaluated in relation to scores on standardized neuropsychological tests. RESULTS The neuropsychological test results were normal for eight individuals, whereas the remaining nine patients exhibited various degrees of cognitive impairment. There was no correlation between the concentrations of arginine vasopressin or neuropeptide Y and test performance. However, significant correlations between cognitive impairment and elevated levels of beta-endorphins (P = 0.02), corticotropin-releasing factor (P = 0.004), and delta sleep-inducing peptide (P = 0.045) were noted. CONCLUSION Patients with cognitive impairments after aneurysmal SAH exhibited higher cerebrospinal fluid concentrations of endorphins, corticotropin-releasing factor, and delta sleep-inducing peptide than did those with normal capacity. This is probably attributable to diffuse derangement of transmitter release in the brain, resulting from the insult or ensuing complications, although a secondary increase in corticotropin-releasing factor concentrations caused by increased stress during the testing because of reduced cognitive capacity cannot be excluded.

Abstract
Endothelial cell dysfunction may contribute to cerebral vasospasm and aggravation of ischemic brain damage following subarachnoid hemorrhage (SAH). It has been suggested that oxyhemoglobin derived from subarachnoid blood clots might be a prime candidate for cerebral vasospasm. In this study, cisternal bloody cerebrospinal fluid (bCSF) was collected from SAH patients four and seven days after aneurysmal rupture, and the effects of bCSF on the cell growth and intracellular calcium ion ([Ca2+]i) dynamics were investigated in cultured human umbilical vein endothelial cells. CSF collected from patients undergoing other intracranial surgeries was used as a control. Pre-treatment with bCSF4 significantly facilitated cell proliferation and DNA synthesis in the cultured endothelial cells, and significantly enhanced histamine-induced [Ca2+]i increase, while acute treatment of the bCSF elicited no [Ca2+]i change. Pre-treatment with interleukin-1 beta showed a similar significant enhancement of the histamine-induced [Ca2+]i response, while pre-treatment with high concentrations of serum or interleukin-6 did not change the [Ca2+]i response. It is concluded that bCSF collected from SAH patients contains some substances which enhance endothelial cell proliferation and sensitivity to inflammatory mediator.

Abstract
OBJECT Whereas the removal of subarachnoid blood is possible during early-stage aneurysm surgery, this cannot be achieved in aneurysms treated by endovascular means. The levels of potential spasmogens in the cerebrospinal fluid (CSF) in patients receiving endovascular treatment might therefore be higher, with the potential for more severe post-subarachnoid hemorrhage (SAH) vasospasm. METHODS Serum and CSF concentrations of big endothelin (ET)-1 were serially measured in patients with SAH receiving one of the following treatments: 1) early (within 72 hours of SAH) aneurysm surgical treatment (15 patients), 2) early endovascular treatment (17 patients), or 3) no intervention in the acute phase (12 patients). In patients suffering delayed infarctions higher levels of big ET-1 CSF were demonstrated than in those without infarctions (p = 0.01). In patients in whom surgery was performed in the acute phase lower big ET-1 CSF concentrations were demonstrated than in those who received embolization treatment or no treatment (p = 0.02). Subgroup analysis demonstrated that in patients receiving early endovascular treatment, higher big ET-1 CSF concentrations were revealed than in those undergoing early aneurysm surgery; this was true for patients with (microsurgerytreated, 1.84 +/- 0.83 pg/ml; and embolization-treated 2.19 +/- 0.54 pg/ml) and without (microsurgery-treated 1.76 +/- 0.61 pg/ml; and embolization-treated 2.01 +/- 0.48 pg/ml) delayed infarctions. CONCLUSIONS Among patients with SAH who received treatment during the acute phase, those undergoing early aneurysm surgery were shown to have lower big ET-1 CSF levels than those receiving embolization and no treatment (that is, the nonsurgical treatment groups). The clinical significance of this finding remains to be established in future clinical trials, because in the present study the trend toward lower levels of big ET-1 CSF in the microsurgically treated group was not paralleled by a lower delayed stroke rate or an improvement in neurological outcome.

Abstract
Trypsinogen was identified in cerebrospinal fluid (CSF), where it has not previously been reported and its activation state in experimental subarachnoid haemorrhage (SAH) in rats and in neurosurgical patients was determined. Trypsinogen activation peptide (TAP) release provided an equimolar marker for trypsinogen. Total TAP was significantly reduced to 26% of the baseline level (P<0.02) following experimental SAH in 15 rats but not in ten sham operated controls (P=0.3). TAP was also measured in patients with ruptured (n=11) and unruptured (n=9) aneurysms who underwent craniotomy to clip an aneurysm. Postoperatively there was a significant fall in TAP concentration (P<0.005) in both groups. Trypsinogen, as identified by CSF levels of TAP, is activated by SAH in rats and by craniotomy for aneurysmal clipping in patients.

Abstract
We measured the concentration of lipocalin-type prostaglandin D synthase (PGDS) in cerebrospinal fluid (CSF) and serum in patients 1, 3, 5, 7, 9, 11, 14 and 17 days after subarachnoid hemorrhage (SAH) due to ruptured cerebral aneurysms. The PGDS level in lumbar CSF increased about two-fold at day 3 (20.85 +/- 2.71 microg/ml, mean +/- SE) and at day 5 (25.24 +/- 3.76), as compared with the level at day 1 (11.25 +/- 1.07). The CSF level gradually decreased and returned to the day 1 level at day 17. The serum PGDS level was much lower than the CSF level (0.39 +/- 0.06 at day 1) and almost unchanged until day 17. The neuron-specific enolase level in CSF, as an index of brain damage, was maximum at day 1 (29.83 +/- 7.32 ng/ml) and decreased at day 3 and at day 5 (18.28 +/- 2.65 and 11.95 +/- 1.82, respectively). These results suggest that the transient and delayed increase in the PGDS level in CSF is due to its induction of PGDS in the arachnoid membrane after SAH.

Abstract
The relationship between lipid peroxidation products and the severity of arterial spasm was studied in 86 patients. For this, the level of radical production, the content of the end lipid peroxidation product malonic dialdehyde and the overall antioxidative activity of lumbar cerebrospinal fluid were determined during 24-hour Doppler monitoring of blood flow in the middle cerebral and internal carotid arteries. Following subarachnoidal hemorrhage, the activation of lipid peroxidation processes was shown to correlate with the severity of arterial spasm and it is likely to contribute to the development of late ischemias. Nimotop used to treat patients with significant arterial spasm caused a reduction in the rate of free radical lipid peroxidation to that characteristic for patients with moderate spasm. The findings suggest that it is expedient of including antioxidants into the combined therapy of patients with acute subarachnoidal hemorrhage.

Abstract
OBJECT The goal of this study was to explore whether the levels of soluble adhesion molecules were elevated in cerebrospinal fluid (CSF) after subarachnoid hemorrhage (SAH). This association was suggested by the known inflammatory response in vasospasm and the role of vascular adhesion molecules in regulating leukocytic adhesion to, and migration across, vascular endothelium. METHODS A prospective analysis was performed on CSF samples obtained in 17 patients who had suffered a recent aneurysmal SAH and in 16 control patients by using quantitative enzyme-linked immunosorbent assays for E-selectin, intercellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1), and L-selectin. Levels of soluble forms of E-selectin (p=0.0013), ICAM-1 (p=0.0001), and VCAM-1 (p=0.048) were found to be elevated in the CSF of patients after SAH compared with levels in the CSF of norminal controls, patients with unruptured aneurysms, and patients tested months after SAH occurred. In addition, individual patients tested at the time of their initial ictus demonstrated a fall in adhesion molecule levels over time. Levels of E-selectin (p=0.044) were highest in patients who later developed moderate or severe vasospasm. CONCLUSIONS Adhesion molecules are known to be involved in white cell adherence to the endothelium and subsequent diapedesis and migration in which a role in initiation of tissue damage is postulated. The authors have demonstrated the elevation of three adhesion molecules, with severely elevated levels of E-selectin seen in patients who later develop vasospasm. A correlation with a role of vascular adhesion molecules in the pathogenesis of cerebral vasospasm is suggested.

Abstract
Cytokines are considered as mediators of immune and inflammatory responses. Cisternal CSF levels of interleukin (IL)-6, IL-8, monocyte chemoattractant protein-1 (MCP-1) and of the soluble adhesion molecule E-selectin were evaluated in patients operated on for intracranial aneurysms. Cisternal CSF samples were obtained at surgery in 41 selected patients (31 with diagnosis of subarachnoid hemorrhage (SAH) and 10 control patients operated on for incidental unruptured aneurysms); 14 patients were operated within 72 h after SAH (early surgery) and 17 were operated after day 10 after the hemorrhage (delayed surgery). The CSF levels of cytokines were evaluated using radioimmunoassay and their concentrations were related to the timing of surgery, the amount of cisternal subarachnoid blood clots and the onset of clinical and angiographical evidence of arterial vasospasm. Mean cisternal CSF levels of IL-6, IL-8 and AMCP-1 are significantly higher in samples obtained from patients early operated after SAH, while levels of E-selectin were below the threshold value of the method in all 41 cases. In the early operated group 7 patients presented symptomatic vasospasm: levels of IL-8 and MCP-1 were not significantly different were compared to those of uncomplicated cases; on the other hand, significantly higher levels of IL-6 were shown in the subgroup of patients operated within 72 h after SAH and developing vasospasm. Among the patients undergoing delayed surgery 5 presented symptomatic vasospasm, but no significant difference was shown in cisternal CSF levels of cytokines measured. The results of the present study show that in patients with unruptured aneurysms cytokines are present in cisternal CSF in scarce quantities and that in subarachnoid spaces after SAH there is an impressive increase of IL-6, IL-8 and MCP-1. Moreover, the higher cisternal CSF levels of IL-6 found in the early stage after SAH might have a predictive value regarding the occurrence of symptomatic vasospasm.

Abstract
OBJECT The present study was conducted to estimate the frequency and timing of rebleeding after initial subarachnoid hemorrhage (SAH) from ruptured giant aneurysms. METHODS The authors reviewed records of 109 patients who suffered an initial SAH from a giant aneurysm and were treated at the Mayo Clinic between 1973 and 1996. They represented 25% of patients with giant intracranial aneurysms seen at this institution during that 23-year period. Seven of the patients were residents of Rochester, Minnesota, and the rest were referred from other institutions. The aneurysms ranged from 25 to 60 mm in diameter, and 74% were located on arteries of the anterior intracranial circulation. The cumulative frequency of rebleeding at 14 days after admission was 18.4%. Cerebrospinal fluid drainage, cerebral angiography, and delayed aneurysm recurrence were implicated in rebleeding in some of the patients. Rebleeding was not precluded by intraaneurysm thrombosis. Among those who suffered recurrent SAH at the Mayo Clinic, 33% died in the hospital. CONCLUSIONS Rebleeding from giant aneurysms occurs at a rate comparable to that associated with smaller aneurysms, a finding that should be considered in management strategies.

Abstract
It has been recognised that the level of superoxide dismutase (SOD) significantly increases in CSF as the result of cerebral ischaemic damage. The aim of this study was to correlate the CSF levels of SOD enzymatic activity to the patterns of subarachnoid haemorrhage with regards to ischaemic complications due to vasospasm. A series of 78 patients operated on for intracranial aneurysms was studied; all patients were monitored with serial TCD measurements every second day after SAH. CSF samples were obtained at surgery by cisternal puncture of the subarachnoid cistern nearest to the aneurysm. SOD activity was assayed spectrophotometrically. Mean cisternal CSF level of SOD in 12 control cases (12.99 +/- 2.33 U/ml) is significantly higher (p < 0.01) than in 26 patients operated on between day 1 and 3 from last SAH episode (4.44 +/- 0.7 U/ml) and in 40 patients treated by delayed surgery (7.64 +/- 0.92 U/ml). In 13 patients presenting neurological deterioration related to arterial vasospasm mean cisternal SOD level was 12.23 +/- 1.86 U/ml; in 27 cases without vasospasm mean level was 5.43 +/- 0.7 U/ml (p < 001). The present results suggest that (a) cisternal CSF levels of SOD significantly decreases after SAH, probably in relation to an impaired synthesis in the brain compartment and that (b) a substantial elevation of SOD levels is evident in patients suffering ischaemic complications vasospasm-related. Biochemical events in the brain compartment could influence the expression and release of anti-oxidant enzymes in CSF after SAH.

Abstract
Lipid peroxidation and enhanced arachidonic acid metabolism is activated after blood-brain cell contact. Previous studies have indicated that cysteinyl-leukotrienes (cys-LT) have the capacity to constrict arterial vessels in vivo and in vitro suggesting their involvement in the pathogenesis of cerebral vasospasm. The purpose of this study was to measure the amount of cyst-LT in the cerebro-spinal fluid (CSF) in correlation with transcranial Doppler findings (TCD) in patients with aneurysmal subarachnoid haemorrhage (SAH). In all patients early surgery was performed. In the first cisternal CSF-sample which was already collected intra-operatively an initial peak of cys-LT was detected, followed by decreasing amounts of cys-LT during the next 5 days. The CSF-levels of immunoreactive cys-LT were significantly higher in those patients who showed signs of vasospasm on transcranial Doppler sonography (TCD) (p < 0.001). Normalization of TCD values was accompanied by decreasing levels of CSF-cys-LT. We found a significant correlation between the amounts of immunoreactive cys-LT in cerebrospinal fluid and cerebral vasospasm measured by TCD.

Abstract
OBJECTIVE To investigate nitric oxide (NO) metabolism after subarachnoid hemorrhage (SAH). METHODS We measured the concentrations of the NO metabolites, nitrite and nitrate, in cerebrospinal fluid (CSF) obtained from the cisternal drainage of patients with SAH. Studies were performed for 31 patients who had undergone surgical obliteration of bleeding aneurysms within 3 days of their hemorrhage. The concentrations of nitrite and nitrate in the CSF were measured for 14 days using a nitrate/nitrite kit and samples that were obtained on a daily basis from the cisternal drainage. RESULTS Compared with the control values in the CSF (2.6 +/- 0.4 mumol/L, n = 14) obtained from patients with hemifacial spasm, trigeminal neuralgia, or nonruptured aneurysms, the concentrations of nitrite and nitrate in the CSF were significantly elevated in the acute stage of SAH and remained elevated. The concentration of NO metabolites may correlate with the amount of bleeding, inasmuch as the values in patients in Fisher Group 3 (n = 25) were higher than those in patients in Fisher Group 2 (n = 6). The concentration of nitrate was higher than that of nitrite, suggesting that NO in the subarachnoid space is mainly absorbed by hemoglobin and degraded to nitrate. No differences were demonstrated in patients treated with high doses of methylprednisolone (n = 17) compared with those treated with usual-dose steroids (n = 14). Steroids are known to prevent the formation of inducible NO synthase mediated by inflammatory cytokines. CONCLUSION NO metabolism in the brain is stimulated after SAH. Nitrate is the dominant NO metabolite in CSF after SAH. The involvement of inducible NO synthase in the pathophysiology of NO metabolism after SAH was not clearly suggested based on the present data.

Abstract
Cerebrospinal fluid from patients with aneurysmal subarachnoid hemorrhage induces the elevation of cytosolic free calcium [Ca2+]i in cultured vascular smooth muscle cells. We have purified a [Ca2+]i elevating factor from cerebrospinal fluid of a patient with subarachnoid hemorrhage due to aneurysm rupture. The calcium-elevating protein factor was purified to homogeneity by ammonium sulfate precipitation and a combination of Mono Q, Superose 12, and Mono S columns using liquid chromatography. Fifteen microgram of the purified protein was obtained from 340 mg of cerebrospinal fluid proteins and the molecular mass of the protein was estimated to be 81 kDa by sodium dodecyl sulfate polyacrylamide gel electrophoresis. It was also shown that the purified protein was cross-reactive with anti-human transferrin antibody. These results suggested that transferrin may be involved with the cerebral vasospasm after subarachnoid hemorrhage.

Abstract
A high concentration of a type of cholic acid, 7 alpha-hydroxy-3-oxo-4-cholestenoic acid, is observed in the content of chronic subdural hematoma. To investigate the possible causes, the level of this compound was measured in the cerebrospinal fluid of patients who underwent surgery for aneurysmal subarachnoid hemorrhage or non-hemorrhagic diseases. The maximum level was significantly higher in the aneurysmal subarachnoid hemorrhage patients, indicating that surgical intervention did not cause the postoperative increase in the level of this compound in the cerebrospinal fluid. Monitoring of plasma levels showed no postoperative increase. In vitro culture of a mixture of arterial blood and cerebrospinal fluid failed to show the de novo production of this compound. These results strongly suggest extrahepatic intracranial production of this cholic acid occurs in subarachnoid hemorrhage. The high concentration of this compound in both chronic subdural hematoma and subarachnoid hemorrhage suggests a possible role for 7 alpha-hydroxy-3-oxo-4-cholestenoic acid in intracranial hemorrhagic disorders.

Abstract
A possible involvement of perivascular vasodilatory neuropeptides in subarachnoid haemorrhage (SAH) has been evaluated in man by measuring the levels of calcitonin gene related peptide (CGRP)-, substance P (SP)- and vasoactive intestinal peptide (VIP)-like immunoreactivity (LI) in the cranial venous outflow and in CSF in 34 patients admitted to the hospital after an acute SAH. After operation with aneurysm clipping and nimodipine treatment, blood samples were taken from the external jugular vein (EJV) or cerebrospinal fluid (CSF) and analysed for neuropeptide levels with specific radioimmuno assays (RIA) during the postoperative course. The degree of vasoconstriction in the patients was monitored with Doppler ultrasound recordings bilaterally from the middle cerebral (MCA) and internal carotid arteries (ICA) following the EJV blood sampling every second day. The mean value of all CGRP-LI measurements in EJV during the entire course of SAH (n = 20) revealed a significantly higher level as compared to controls. The highest CGRP-LI levels were found in patients with the highest velocity index values (vasospasm). The relationship Vmean MCA/Vmean ICA was used as an index of vasoconstriction. In patients with MCA aneurysms (n = 10), a significant correlation (r = 0.65, p < 0.05) was found between the vasospasm index and CGRP-LI levels. There were no changes observed in the SP- and VIP-LI levels. Alterations in cerebrovascular tone induced by changing arterial CO2 tension or lowering of blood pressure (ketanserin infusion test) did not alter the levels of the perivascular peptides in the EJV. In addition, CGRP-, SP-, VIP- and neuropeptide Y (NPY)-LI were analysed in CSF in the post-operative course after subarachnoid haemorrhage (SAH) in 14 patients. The CSF VIP-LI was lower in SAH than in control (p < 0.05). The CGRP-LI level was measurable in SAH CSF but not in CSF of controls. In individual patients with marked vasoconstriction increased levels of CGRP-LI (up to 14 pmol/L) and NPY-LI (up to 232 pmol/L) were observed. The results of this study are in support of our hypothesis that there is an involvement of the sensory peptide CGRP in a dynamic reflex aimed at counterbalancing vasoconstriction in SAH.

Abstract
CSF eicosanoid levels are raised following subarachnoid haemorrhage but not sufficiently to be vasoactive per se within the cerebral circulation. Rebleeding and intraventricular haemorrhage are two factors associated with a worse outcome after aneurysmal SAH. We have examined the effects of these two factors on the CSF levels of TXB2 (TXA2 metabolite), PG6-keto F1 alpha (prostacyclin metabolite), PGF2 alpha and PGE2 in 44 patients following subarachnoid haemorrhage. In 15 patients who had received no non-steroidal anti-inflammatory agent or dexamethasone, intraventricular haemorrhage increased the median levels of all four eicosanoids in ventricular CSF by 2.1-5.1-fold. In 4 patients who rebled, the CSF median levels of all four eicosanoids were raised up to 250-fold over the normal range. These concentrations are just sufficient to have cerebrovascular and neuromodulatory effects.

Abstract
To investigate the clinical significance of endothelin (ET), a potent vasoconstrictor peptide, in subarachnoid hemorrhage (SAH) and SAH-related cerebral vasospasm, we measured the ET-like immunoreactivity (ET-LI) in plasma and cerebrospinal fluid (CSF) obtained serially from patients with SAH due to ruptured cerebral aneurysm who underwent aneurysmal surgery. The normal ET-LI levels in plasma and CSF (n = 24) were 12.4 +/- 2.0 (mean +/- s.d.) and 9.1 +/- 1.2 pg.ml-1, respectively. Plasma ET-LI levels in patients with SAH before surgery (16.8 +/- 7.8 pg.ml-1, n = 8) were higher than the normal values (P < 0.05), and became further elevated after surgery (22.5 +/- 9.4 pg.ml-1). ET-LI levels in plasma and CSF one day after surgery were 18.7 +/- 5.5 and 18.4 +/- 6.8 pg.ml-1 (P < 0.01 vs. normal values), respectively, and declined thereafter. The plasma and CSF ET-LI levels in patients who showed symptomatic vasospasm became concomitantly elevated again. These results suggest that ET is involved in SAH-related vasospasm and raise the possibility that surgical stress influences the vasospasm.

Abstract
Acetylcholine (ACh) concentrations were determined serially in cerebrospinal fluid (CSF) obtained from 23 patients with aneurysmal subarachnoid hemorrhage (SAH) by high-performance liquid chromatography (HPLC) with electrochemical detection (ED). The values of CSF ACh were significantly low in the initial stage of SAH, and increased subsequently but they did not return to control values within 3 weeks. In addition, serial measurements of CSF butyrylcholinesterase (BChE) activity in 12 SAH patients showed that the activity was elevated significantly in the initial stage of SAH and returned to control levels within a week. This discrepancy in the recovery period between the ACh levels and the BChE activity in CSF indicated that significantly lower CSF ACh levels after SAH could not be attributed to plasma BChE contamination of CSF. These results suggested central cholinergic dysfunction after SAH, especially in the initial stage.

Abstract
The attitude concerning early clipping of aneurysms or generally aneurysm surgery in poor grade patients is controversial. There is no discussion about the space-occupying haematomas that must be removed urgently even in grade V patients if they have been admitted immediately after the acute event. Several patients in grade IV or V following a pure subarachnoid haemorrhage, can be improved by external ventricular drainage and thereafter their aneurysm operated upon with a better chance. Intelligible, the frequency of shunts needed is higher in poor than in good grade patients. Nevertheless, it can be reduced if the pressure, against what CSF is drained off, is kept on a higher level (about 20 cm H20) once the patient has stabilised. It also appears recommendable to operate upon aneurysms in patients who persist for several days in a condition no better than grade IV, rather than to assume an expectative attitude, for aneurysm rerupture mostly terminates the life of the patient, whereas clipping gives a change of recovery.

Abstract
The authors examined the semiotics of hydrocephalus occurring after subarachnoidal hemorrhages (SAH) from arterial aneurysms and arteriovenous malformations to provide pathogenetic evidence for surgical or conservative hydrocephalus. The spinal fluid tract was examined in 44 patients after SAH by computed tomography and radionuclide cysternomyelography using 99mTc. Variability was found in the radiological semiotics of open internal hydrocephalus. Radiological studies revealed frequently open internal hydrocephalus in patients with arterial aneurysms and arteriovenous malformations without subarachnoidal hemorrhages. The radiological semiotics of open hydrocephalus after SAH determines both morphological changes of the spinal fluid tract and liquorodynamic disturbances.

Abstract
Phosphoinositide-specific phospholipase C (PLC) activities were measured in CSF from patients after subarachnoid hemorrhage (SAH). Their PLC activities were significantly higher than those in control CSF. Moreover, there was an obvious correlation between the PLC activity in CSF collected on day 3 and the preoperative clinical grade. The PLC activity was also closely correlated with the level of neuron-specific enolase as a marker of brain damage. Furthermore, the PLC activities were partially purified from CSF of patients after SAH and were immunologically identified to be PLC beta, PLC gamma, and PLC delta. These results suggest that PLCs are released into the CSF from brain tissue in conjunction with the initial hemorrhage and that their activity may reflect the extent of brain damage.

Abstract
Ventricular cerebrospinal fluid (CSF) lactate concentrations and lactate/pyruvate (L/P) ratios were measured daily in 20 patients from day 1 to day 12 after subarachnoid haemorrhage due to ruptured aneurysms. Patients without symptomatic vasospasm were classified in Group 1, patients with symptomatic vasospasm were classified in Group 2, and patients who were Hunt and Kosnik grade 4 on admission clinically were classified in Group 3. Patients in all three groups had high CSF lactate concentrations on day 1, and, especially in Group 3, the high lactate was accompanied by an increased L/P ratio and a decreased CSF bicarbonate. Lactate concentrations in Group 1 decreased throughout the observation period. Lactate concentrations in Group 2 also decreased but then began to increase again on days 5 to 7, correlating well with the onset of cerebral vasospasm. The delayed increase of CSF lactate in Group 2 was also accompanied by increases in the CSF pyruvate level and the CSF L/P ratio. Daily monitoring of CSF lactate may thus serve as a chemical marker for cerebral vasospasm.

Abstract
A CT scan done on admission showed widening of the ventricular system in 56 (34%) out of 164 patients with a ruptured intracranial aneurysm. 82% of the patients were admitted within 5 days after the bleeding. Those with hydrocephalus were often in a poor clinical condition (grades 3-5 Hunt and Hess, p less than 0.01) with up-going plantars twice as frequently encountered as in the remaining group. Widening of the ventricles adversely affected the prognosis. With hydrocephalus rebleeding was more frequent (p less than 0.02) and so was the ischaemic neurological deficit, whereas long-term treatment results were worse (p less than 0.01) with a double mortality rate (p less than 0.02). Hydrocephalus was more frequent in older patients (p less than 0.001 and in those with posterior fossa aneurysms (p less than 0.005). It was also promoted by diffuse and extensive bleeding into the subarachnoid space (p less than 0.01) and by intraventricular haemorrhage (p less than 0.0001). Three patients were treated with ventricular drainage.

Abstract
Cardiac- and respiration-related movements of the cerebrospinal fluid (CSF) were investigated by MRI in 71 patients. In most patients with arteriosclerotic occlusive vascular disease CSF pulsations are normal. Decreased pulsatile flow is detectable in those with arteriovenous malformations, intracranial air and following lumbar puncture and withdrawal of CSF. Increased pulsatile flow in the cerebral aqueduct was found in 2 patients with large aneurysms, idiopathic communicating syringomyelia and in most cases of normal pressure hydrocephalus (NPH). CSF flow in the cervical spinal canal is, however, reduced or normal in NPH, indicating reduction of the unfolding ability of the surface of the brain and/or inhibition of rapid CSF movements in the subarachnoid space over its convexity.

Abstract
It was established from study of lipid peroxidation (LOP) products in 19 patients (16 with subarachnoid hemorrhages /SAH/ resulting from rupture of arterial aneurysms and 3 with arterial hemorrhages in the "cold" period) that their content was significantly higher in patients with a history of 2 or 3 SAH than in those who had suffered from a single SAH. The LOP level in the c.s.f. in patients of both groups differed significantly from that in the c.s.f. of patients without SAH. It was also established that the content of LOP products in patients with an unfavourable outcome of the disease was more than twice that in patients with a favourable course and outcome of the disease. Administration of antioxidants (alpha-tocopherol and ascorbic acid) inhibited the LPO processes, which was manifested by a decrease of the content of malonyl dialdehyde in the c.s.f.

Abstract
Using a spectrofluorometric method, the concentration of the major monoamines, norepinephrine (NE), dopamine (DA), 5-hydroxytryptamine (5-), and 5-hydroxyindoleacetic (5-HIAA) was determined in cerebrospinal fluid (CSF) of patients with subarachnoid aneurysm before its rupture. DA, 5-HT, and 5-HIAA levels in CSF were found significantly increased when compared with the corresponding values found in persons with no clinical alterations of central nervous system (CNS). No significant differences were seen in NE values in CSF when data from patients with subarachnoid aneurysm were compared to their control subjects. Data obtained suggest that of NE diffusion to CSF could be at a different rate than that of the other monoamines measured. Alternatively, the reuptake of NE could vary in relation with that to the other monoamines in the affected brain tissue during the onset and development of the aneurysm. Results may also indicate a possible accumulation of NE in brain tissue adjacent to the damaged areas as a result of an increased monoaminergic activity, which, could be involved in the pathophysiology of aneurysm rupture.

Abstract
We investigated the possible relation between neuropeptides and cerebral vasoconstriction in samples of ventricular or cisternal cerebrospinal fluid from 14 patients with subarachnoid hemorrhage. Neuropeptide Y, calcitonin gene-related peptide, atrial natriuretic peptide, and pituitary polypeptide 7B2 were present in the cerebrospinal fluid of these patients. Concentrations of calcitonin gene-related peptide and 7B2 were not significantly different from those in control subjects, but that of atrial natriuretic peptide was significantly lower. Although the mean concentration of neuropeptide Y was not significantly higher than control, consecutive determinations showed an increase 6-11 days after the onset of subarachnoid hemorrhage. An initially high 7B2 concentration decreased gradually, although half the patients showed a second increase greater than 10 days after the onset. Considering the well-recognized vasoconstrictive effect of neuropeptide Y, it is possible that this increase in its concentration in the cerebrospinal fluid plays a role in the pathogenesis of the cerebral vasospasm that is often seen after subarachnoid hemorrhage.

Abstract
Cisternal and/or ventricular cerebrospinal fluid (CSF) and arterial blood lactate and acid-base balance were measured serially in 38 patients with aneurysmal subarachnoid haemorrhage (SAH). Based on daily clinical assessment, the patients and accordingly the samples were divided into two groups according to the grading of the World Federation of Neurosurgical Societies (W.F.N.S.). In cisternal CSF, samples of Grade III-V showed significantly higher lactic acidosis than those of Grade I-II. The time course of lactate and pH in poor prognosis groups had a significant tendency of lactic acidosis, especially on the 5th, 6th, 7th day after SAH. Ventricular CSF lactate increased even without CSF acidosis in Groups III-V. Measurement of CSF lactate, especially from the cisterna magna is useful as an indicator of prognosis and changes of intracranial environment following SAH.
