Abstract
OBJECTIVE As soon as possible treatment initiation for aneurysmal subarachnoid hemorrhage (aSAH) is recommended. However, some patients require treatment in "subacute" phase of aSAH, defined in this study as "more than one day after the onset". To establish an optimal treatment strategy for these patients, we retrospectively analyzed the clinical experience of treating ruptured aneurysm with either clipping or coiling in subacute phase. METHODS Patients treated for aSAH between 2015 and 2021were analyzed. Patients were divided into the hyperacute phase (within 24 h) and subacute phase (later than 24 h) groups. The subacute group was analyzed to determine whether the selected procedure and its timing affected postoperative course and clinical outcomes. In addition, we conducted a multivariate logistic regression analysis to determine the independent factors that affect clinical outcomes. RESULTS Of 215 patients, 31 were treated in the subacute phase. While cerebral vasospasm at initial imaging was more frequently observed in subacute group, there was no difference in incidence of postoperative vasospasms. Patients in subacute group seemed to have better clinical outcomes due to the milder severity at the time of treatment initiation. Risk of angiographic vasospasm seemed to be higher in patients treated with clipping than coiling, while no difference was seen in clinical outcomes. Multivariate logistic regression analysis showed that the timing and selected treatment did not significantly affect the clinical outcome or the occurrence of delayed vasospasm. CONCLUSIONS Treatment of aSAH in the subacute phase may also result in favorable clinical outcomes, similar to patients treated in the hyperacute phase with mild presentation. However, further investigations are required to establish the optimal treatment strategies for such patients.

Abstract
During intracranial tumor resection, the delayed kinking of a major encased vessel has never been described in literature. We present a case which required urgent endovascular treatment performed through a stent positioning. A patient was hospitalized with symptomatic sphenoid meningioma in the left middle cranial fossa. Twelve days after surgery, right-sided hemiplegia and aphasia occurred. Digital subtraction arteriography revealed a kinking of the M1 segment of the left middle cerebral artery and diffuse vasospasm. At first, intra-arterial nimodipine has been administered, obtaining the remission of the vasospasm. Secondly, a stent was positioned to treat the kinking, achieving a complete flow restoration.

Abstract
AIM The study purpose was to analyze the efficacy of intra-arterial administration of verapamil (IAV) in the treatment of angiospasm in SAH patients and to determine optimal parameters of the procedure. A number of studies demonstrated the efficacy of intra-arterial administration of vasodilators, in particular verapamil, in the treatment of angiospasm after aneurysmal SAH, which served the basis for inclusion of this method in the recommended protocol for treatment of SAH patients [1-7]. MATERIAL AND METHODS We analyzed the efficacy of IAV in 35 patients in the acute period of SAH, with 77.2% of the patients having a Hunt-Hess score of III-V. The inclusion criteria were as follows: IAV within two weeks after SAH; excluded aneurysm; verapamil dose per administration of at least 15 mg; follow-up for at least three months. Efficacy endpoints were as follows: changes in spasm according to angiography and transcranial dopplerography (TCDG); development of ischemic lesions; clinical outcome according to the modified Rankin scale. RESULTS A total of 76 IAV procedures were performed. The verapamil dose per procedure was 36.7±9.7 mg, on average; the number of procedures varied from 1 to 5. One arterial territory was treated in 12 cases, two arterial territories were treated in 48 cases, and three arterial territories were treated in 15 cases. Typical adverse reactions included decreased blood pressure, a reduced heart rate, and elevated ICP. In all cases, TCDG revealed signs of reduced angiospasm - a 20-40% decrease in the LBFV in the M1 MCA. Four (11.4%) patients died; of these, only one died due to angiospasm progression. On examination at 3 months or more after discharge, favorable outcomes were observed in 74.3% of cases. CONCLUSION IAV is associated with a low risk of significant complications. IAV should be performed under control of systemic hemodynamics and ICP. The indications for IAV include signs of moderate worsening or severe angiospasm according to TCDG and/or angiography. The IAV procedure may be performed every day. Further clarification of the IAV procedure and evaluation of clinical outcomes under prospective study conditions are required.

Abstract
PURPOSE We evaluated patients treated with prophylactic intra-arterial administration of fasudil hydrochloride (IAF) after subarachnoid haemorrhage (SAH). MATERIALS AND METHODS Between August 1998 and December 2012, 92 patients with aneurysmal SAH were treated with IAF for angiographic vasospasm without ischemic symptoms after their follow-up angiography. Patients comprised 50 women and 42 men, aged 24-83 (mean 56.6) years. IAF consisted of 15 mg of fasudil hydrochloride dissolved in 20 ml physiological saline and injected through a catheter during approximately 15 min, after diagnostic angiography. The clinical outcome was evaluated using the Glasgow Outcome Scale (GOS) at discharge and ischemic lesions resulting from vasospasm were assessed on computed tomography (CT) scan at discharge. RESULTS Forty-eight patients underwent surgical clipping and 44 patients underwent endovascular coiling. Angiographic improvement was observed in all patients (100 %). At discharge, 76 (83.0 %) of 92 patients showed good recovery on GOS. Nine patients developed progression of delayed ischemic neurological deficits (DIND) and three of these patients had ischemic lesions on CT scans. No patient had any significant changes in vital signs or any other adverse effects resulting from IAF. CONCLUSION IAF therapy was safe and effective for patients with vasospasm following SAH. Prophylactic IAF therapy may prevent symptomatic vasospasm.

Abstract
BACKGROUND Delayed vasospasm (VSP) following aneurysmal subarachnoid hemorrhage (aSAH) remains a major source of morbidity. Milrinone was recently suggested as an invasive VSP treatment option. It is a phosphodiesterase III inhibitor with vasodilating and additional positive inotrope and anti-inflammatory effects. METHODS In this preliminary series, we included patients with severe VSP and unsuccessful maximum conservative therapy. Inclusion criteria were (1) transcranial Doppler (TCD) mean >180 cm/s; (2) increase of >50 % of TCD mean values within 6 h to values >150 cm/s; and/or (3) neurological deterioration (after exclusion of hemorrhage, hydrocephalus, and other systemic reasons). Patients received endovascular therapy with nimodipine 2 mg followed by milrinone 4-8 mg. Reinterventions were indicated aggressively in cases of persistent neurological deficits or persistent high mean TCD >180 cm/s. RESULTS Of 121 consecutive aSAH patients, 16 (13.2 %) received endovascular VSP therapy. Of these, 11 patients (68.5 %) received ≥ 3 interventions (median 4; maximum 9); 14 (87.5 %) showed postinterventional angiographic improvement of vessel diameters; and 11 (68.5 %) showed improvement of their neurological deficits after a mean follow-up time of 4.5 months. No cardiovascular adverse events attributed to milrinone were observed. CONCLUSIONS Milrinone may be a useful supplementary substance for endovascular VSP therapy. Aggressive reintervention indications did not cause additional adverse events.

Abstract
OBJECTIVES To assess the involvement of ficolin-3, the main initiator of the lectin complement pathway (LCP), in subarachnoid hemorrhage (SAH) pathology and outcome. METHODS In this preliminary exploratory study, plasma concentration of ficolin-3 and of ficolin-3-mediated functional LCP activity was measured, along with that of other LCP initiators (mannose-binding lectin, ficolin-2, and ficolin-1), C3 activation products, and soluble C5b-9 terminal complex, in a prospective cohort of 39 patients with SAH and 20 healthy controls. The following parameters were recorded: SAH severity, assessed using the World Federation of Neurosurgical Societies grading scale; vasospasm, defined as neuro-worsening with angiographic confirmation of vessel narrowing; cerebral ischemia, defined as hypodense lesion on CT scan performed before discharge; and 6-month outcome, assessed using the Glasgow Outcome Scale. RESULTS In patients, no changes were detected for ficolin-3 compared with controls. Notably, however, ficolin-3-mediated functional LCP activity was reduced. Low levels of plasma ficolin-3 and ficolin-3-mediated functional LCP activity were related to SAH severity, vasospasm, and cerebral ischemia. Moreover, ficolin-3 functional LCP activity was decreased in patients with unfavorable outcome. CONCLUSION Our data provide evidence that LCP is activated after SAH and that the actual plasma concentrations of ficolin-3 reflect the severity of brain injury as evaluated by clinical and structural parameters. These results support the idea that ficolin-3-mediated functional LCP activity may be targeted to control injury progression in SAH.

Abstract
OBJECTIVE To evaluate the effect of aneurysm clipping and partial blood clot removal in the subarachnoid space on hemorrhage volume in the subarachnoid space and cerebral vasospasm in patients with different Fisher grades. METHODS Patients with subarachnoid space hemorrhage (SAH) of Fisher Grades I, II, and III were subdivided into control and treatment groups for comparative studies. The patients with unruptured intracranial aneurysms (UIAs) undergoing aneurysm clipping were also compared with Fisher grade I control subgroup. OxyHb levels in the cerebrospinal fluid and cerebral blood flow volume (CBFV) of the middle cerebral artery (MCA) were measured on days 3, 7, and 13 day after SAH. RESULTS The patients with UIAs and Fisher Grade I control subgroup showed significant differences in OxyHb levels on day 3 in CBFV of the MCA on days 3 and 7 (P<0.05). In the SAH groups, OxyHb levels increased significantly on day 3 day in the treatment subgroups of Fisher Grades I and II, but declined significantly on days 7 and 13 in Fisher Grade III treatment subgroup as compared with the corresponding control subgroups (P<0.05); in Fisher Grade I group on days 3 and 7 and in Fisher Grade II group on day 7, CBFV of the MCA increased significantly in the treatment subgroups, but in Fisher Grade III group, CBFV decreased significantly on days 7 and 13 compared with the control subgroup (P<0.05). A positive correlation was found between OxyHb levels in the cerebrospinal fluid and CBFV of the MCA (P<0.05). CONCLUSION For patients with Fisher Grades I and II aneurysms, craniotomy may increase hemorrhage volume in the subarachnoid space and exacerbate cerebral vasospasm, but for Grade III patients, aneurysm clipping and blood clot removal shows beneficial effects in terms of reducing hemorrhage volume and relieving cerebral vasospasm.

Abstract
Symptomatic cerebral vasospasm (CVS) after transsphenoidal surgery (TSS) is very rare compared with vasospasm resulting from aneurysmal subarachnoid hemorrhage (SAH). Fewer than six cases documented by cerebral angiography have been reported. We evaluated the records of 15 patients in whom SAH developed after TSS. Their clinical symptoms, radiological and laboratory findings were analyzed. Among 15 patients with postoperative SAH, 11 did not show CVS during their postoperative course. However, four patients presented with various clinical symptoms suggestive of CVS on postoperative days 7-9. They showed an abrupt drop of serum sodium level 1 or 2 days before the onset of CVS symptoms. Patients with TSS-related SAH should be managed with proactive and aggressive treatment. Hyponatremia, which usually occurs around the first week after TSS, should not be ignored as a matter of metabolic or hormonal disequilibrium commonly encountered after pituitary surgery.

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
BACKGROUND Increased nuclear factor κB (NF-κB) bioexpression, as well as TNF-α, IL-1β and IL-6 levels, were observed after aneurysmal subarachnoid hemorrhage (SAH). It is of interest to investigate the effect of 6-mercaptopurine (6-mp) on cytokines/NF-κB in this SAH model. MATERIALS AND METHODS A rodent double-hemorrhage SAH model was employed. Serum and cerebrospinal fluid (CSF) samples were collected to examine IL-1, IL-6 and TNF-α levels. NF-κB subunit p65 and its inhibitor of nuclear factor κB (IκB) were examined (by Western blot). TNF-α was used to induce the phosphorylation of IκB in the presence or absence of 6-mp. RESULTS Nuclear NF-κB subunit p65/IκB kinase in the basilar artery was over-expressed, and cytokines was notably increased in the SAH groups, compared with the controls (P < 0.01). In the 6-mp SAH group, obvious reduction was observed in NF-κB subunit p65 (nuclei) (P < 0.01). Treatment with 6-mp significantly reduced IL-1β and TNF-α levels to those of the healthy control. 6-Mercaptopurine also significantly increased the level of IκB in the TNF-α-stimulated SAH rats. CONCLUSIONS Through inhibiting IκB bioexpression, 6-mp decreases NF-κB-related IL-1β, IL-6, and TNF-α in the presence of SAH. The study suggests 6-mp exerts vascular anti-inflammatory properties through inhibiting IκB kinase and subsequently blocks bio-activation of NF-κB and related cytokines, which may contribute to its antivasospastic effect in animals subjected to SAH.

BACKGROUND AND PURPOSE Cerebral vasospasm resistant to medical management frequently requires intra-arterial spasmolysis. Angiographic resolution of vasospasm does not provide physiologic data on the adequacy of reperfusion. We recorded pre- and postspasmolysis PbO(2) data in the endovascular suite to determine whether this physiologic parameter could be used to determine when successful reperfusion was established. MATERIALS AND METHODS Eight patients with 10 Licox monitors and cerebral vasospasm underwent intra-arterial spasmolysis. Pre- and postspasmolytic PbO(2) was recorded for comparison. Other physiologic parameters, such as CPP, ICP, SaO(2), and Fio(2), were also recorded. RESULTS Mean prespasmolysis PbO(2) recordings were 35.2 and 27.3 for the mild-to-moderate and moderate-to-severe vasospasm group, respectively. Mean postspasmolysis PbO(2) increased to 40.3 and 38.4, respectively, which was statistically significant (P < .05) for both groups. In 100% of instances in the moderate-to-severe group and 83% of instances in mild-to-moderate group, the mean PbO(2) increased after spasmolysis and correlated with improvement in angiographic vasospasm. Other physiologic parameters, such as CPP, ICP, SaO(2), and Fio(2), did not show any statistically significant difference before and after spasmolysis. CONCLUSIONS PbO(2) monitoring provides the interventionalist with an objective physiologic parameter to determine adequate spasmolysis. Further investigation is needed to establish target PbO(2) rates indicative of adequate reperfusion, which can be used in the endovascular suite.

Abstract
Chiari I malformation (CM) is usually associated with CSF flow disturbances at the level of craniovertebral junction. In current literature a few articles aim to demonstrate blood flow disturbances in Chiari I malformation patients. The paper discusses the role of posterior atlantooccipital membrane in vertebrobasilar insufficiency development and presents a case of successful treatment of blood flow alterations after decompression of craniovertebral junction and posterior atlantooccipital membrane resection.

Abstract
OBJECTIVE The purpose of the present study was to compare the effects of early and late surgery on postoperative vasospasm and mortality in patients with subarachnoid hemorrhage (SAH). METHODS The data of patients with SAH who underwent aneurysmal clipping at the Kartal Training and Research Hospital between 1999 and 2005 were retrospectively analyzed. The patients who underwent early (0-3 days) and late surgery (> or = 4 days) were evaluated as two groups. Patient outcomes were assessed 1 month after surgery. RESULTS Of 159 patients (mean age, 49 years; 71 males) with SAHs, 135 (mean age, 51 years; 55 males) underwent early surgery and 24 patients (mean age, 56 years; 16 males) underwent late surgery. The overall postoperative vasospasm rate was 10.7%. The rate of postoperative vasospasm was significantly higher in the late surgery group (41.7%) compared to the early surgery group (5.2%; p < 0.001). There were 15 post-operative deaths (9.4%). The mortality rate in the late surgery group (25.0%) was significantly higher than the early surgery group (6.7%; p = 0.005). CONCLUSIONS The present study has demonstrated that early surgery is advantageous over late surgery in patients with SAH with lower post-operative vasospasm and mortality rates.

Abstract
BACKGROUND We report six new cases of ischaemic stroke after cerebral haemorrhage in patients with moyamoya disease (MMD) and analyse their clinical and radiological characteristics, together with cases reported in the literature, to deduce the mechanism of cerebral infarct. METHODS Six (2%) of 246 patients with MMD who were admitted to our hospitals between 1993 and 2009 suffered cerebral infarct after intracranial haemorrhage. Ten patients identified in the literature with the PubMed search engine were also included in this study. All the ischaemic lesions in these 16 patients were analysed according to their location, size, and number and were compared according to the spatial relationship between the haemorrhage and infarct, as follows: (1) anterior vs posterior involvement, (2) cortical vs subcortical involvement, (3) watershed vs non-watershed infarct, (4) small vs large infarct, (5) single vs multiple infarct, and (6) adjacent vs distant involvement. RESULTS Acute synchronous multiple brain infarcts occurred in six (38%) patients and recurrent infarcts in three patients (19%). Cerebral infarcts had mainly cortical (72%), anterior (66%), and distant involvement (75%) and were large (69%) and non-watershed (66%). Adjacent infarct had significantly anterior involvement (P < 0.05), and distant infarcts tended to have cortical involvement. Non-watershed infarcts had significantly cortical involvement (P < 0.05). Watershed infarcts tended to be large. Vasospasm was confirmed either pathologically or angiographically in two patients with large cerebral infarcts. CONCLUSIONS We suggest that thromboembolism or vasospasm plays a crucial role in the pathogenesis of cerebral infarction after acute intracranial haemorrhage in patients with MMD.

Abstract
We report the case of a 54-year-old woman presenting subarachnoid haemorrhage. She experienced multiple vasospasms and treatment included triple-H (hypervolaemia, hypertension, and haemodilution) and endovascular therapies. Right internal carotid dissection complicated angioplasty of the right middle cerebral artery. Combined brain tissue partial pressure of oxygen monitoring and transcranial echo-Doppler could have facilitated early diagnosis. Despite successful revascularization of right internal carotid by stenting, this complication caused acute stroke with refractory intracranial hypertension.

Abstract
OBJECTIVE Blast-related neurotrauma is associated with the severest casualties from Operation Iraqi Freedom (OIF). A consequence of this is cerebral vasospasm. This study evaluated all inpatient neurosurgical consults related to battle injury from OIF. METHODS Evaluation of all admissions from OIF from April 2003 to October 2005 was performed on patients with neurotrauma and a diagnostic cerebral angiogram. Differences between patients with and without vasospasm and predictors of vasospasm were analyzed. RESULTS Fifty-seven out of 119 neurosurgical consults were evaluated. Of these, 47.4% had traumatic vasospasm; 86.7% of patients without vasospasm and 80.8% of patients with vasospasm sustained blast trauma. Average spasm duration was 14.3 days, with a range of up to 30 days. Vasospasm was associated with the presence of pseudoaneurysm (P = 0.05), hemorrhage (P = 0.03), the number of lobes injured (P = 0.012), and mortality (P = 0.029). Those with vasospasm fared worse than those without (P = 0.002). The number of lobes injured and the presence of pseudoaneurysm were significant predictors of vasospasm (P = 0.016 and 0.02, respectively). There was a significant quadratic trend towards neurological improvement for those receiving aggressive open surgical treatment (P = 0.002). In the vasospasm group, angioplasty with microballoon significantly lowered middle cerebral artery and basilar blood-flow velocities(P = 0.046 and 0.026, respectively). CONCLUSION Traumatic vasospasm occurred in a substantial number of patients with severe neurotrauma, and clinical outcomes were worse for those with this condition. However, aggressive open surgical and endovascular treatment strategies may have improved outcome. This was the first study to analyze the effects of blast-related injury on the cerebral vasculature.

Abstract
OBJECTIVE AND IMPORTANCE Aneurysms of the paraclinoid segment arising from the anterolateral wall of the proximal internal carotid artery (ICA) are usually located in the intradural space, and the proximal neck of the aneurysm is closely adjacent to the dural ring. Although most of these aneurysms can be identified by cerebral angiography, the top of the aneurysm can be flattened because of its relationship to the undersurface of the clinoid process. We report a rare case of a ruptured ICA anterolateral wall aneurysm that was not identified by initial angiography but was clearly observed at the time of vasospasm. CLINICAL PRESENTATION A 59-year-old female patient was transferred to our hospital because of sudden loss of consciousness. Initial angiography failed to disclose any aneurysm except for one projecting to the right at the C3-C4 portion of the left ICA. A left frontotemporal craniotomy with drilling of the anterior clinoid process was performed 1 day after the onset of subarachnoid hemorrhage. Within the operative field, however, no hemorrhage was detected near the C3-C4 portion of the left ICA. Subsequent angiography performed during vasospasm clearly demonstrated a ruptured aneurysm in the anterior paraclinoid segment of the right ICA. INTERVENTION After drilling the anterior clinoid process and cutting the dural ring, we successfully clipped the aneurysm. The aneurysm was saccular, with a broad neck that extended below the dural ring. Intraoperative inspection demonstrated that the dome of the aneurysm was in a subclinoid location, suggesting that most of the aneurysm might have been flattened by the dural ring at the time of initial angiography but before the onset of vasospasm. CONCLUSION The presented case suggests that this type of aneurysm may be missed by routine angiography performed before and after vasospasm. If initial angiography fails to reveal the origin of the subarachnoid hemorrhage but computed tomography still discloses hemorrhage from an ICA aneurysm, repeated angiography should be considered within 14 days after the onset of subarachnoid hemorrhage to confirm whether the aneurysm has arisen from the anterior clinoid segment of the ICA.

Abstract
✓ The authors tested the null hypothesis that published literature with a high level of evidence does not support the assertion that subarachnoid hemorrhage (SAH) causes cerebral vasospasm, which in turn causes cerebral infarction and poor outcome after aneurysmal SAH. The medical literature on SAH was searched in MEDLINE. The author's personal files of all published literature on SAH were reviewed. References cited in Cochrane reviews as well as the published papers that were reviewed were also retrieved.
There is no question that SAH causes what the authors have chosen to call “angiographic vasospasm.” However, the incidence and severity of vasospasm in recent series of patients is not well defined. There is reasonable evidence that vasospasm causes infarction, but again, accurate data on how severe and how diffuse vasospasm has to be to cause infarction and how often vasospasm is the primary cause of infarction are not available. There are good data on the incidence of cerebral infarction after SAH, and these data indicate that it is highly associated with poor outcome. The link between angiographic vasospasm and poor outcome is particularly poorly described in terms of what would be considered data of a high level of evidence.
The question as to whether there is a clear pathway from SAH to vasospasm to cerebral infarction to poor outcome seems so obvious to neurosurgeons as to make it one not worth asking. Nevertheless, the obvious is not always true or accurate, so it is important to note that published literature only weakly supports the causative association of vasospasm with infarction and poor outcome after SAH. It behooves neurosurgeons to document this seemingly straightforward pathway with high-quality evidence acceptable to the proponents of evidence-based medicine.

Abstract
Object
Over the past decade, low-pressure, flow-directed balloons have been replaced by over-the-wire balloons in the treatment of vasospasm induced by subarachnoid hemorrhage (SAH). The authors assess the procedural safety and technical efficacy of these newer devices.
Methods
Seventy-five patients who underwent 85 balloon angioplasty procedures for the treatment of SAH-induced vasospasm were identified from a prospective quality-assurance database. Medical records and angiographic reports were reviewed for evidence of procedural complications and technical efficacy.
No vessel rupture or perforation occurred, but thromboembolic complications were noted in four (4.7%) of the 85 procedures. Balloon angioplasty was frequently attempted and successfully accomplished in the distal internal carotid (100%), proximal middle cerebral (94%), vertebral (73%), and basilar (88%) arteries. Severe narrowing was present in 89 proximal anterior cerebral arteries. Angioplasty was attempted in 41 of these vessels and was successful in only 14 (34%). In 19 of the 27 unsuccessful attempts, the balloon could not be advanced over the wire due to severe vasospasm or unfavorable vessel angle. Follow-up angiography in a subset of patients demonstrated that severe recurrent vasospasm occurred in 15 (13%) of 116 vessels studied after angioplasty.
Conclusions
Over-the-wire balloons involve a low risk for vessel rupture. The anterior cerebral artery remains difficult to access and successfully treat with current devices. Further improvements in balloon design, such as smaller inflated diameters and better tracking, are necessary. Finally, thromboembolic complications remain an important concern, and severe vasospasm may recur after balloon angioplasty.

Abstract
This study investigates the role of cervical sympathectomy in the prevention of acute vasospasm induced by meningeal haemorrhage in rabbits. Sixteen adult English Norfolk rabbits were divided into 2 experimental groups: bilateral cervical sympathectomy of the superior sympathetic ganglion (SSSG, n=8), and bilateral SSSG and sympathectomy of the inferior sympathetic ganglion (SISG, n=8). Other 24 animals were used as controls. Basilar artery diameter was evaluated by angiography. SSSG protected the animals against developing cerebral vasospasm; SSSG associated with SISG did not increase this effect.

Abstract
There have been considerable advancements in the medical and surgical management of subarachnoid hemorrhage (SAH) resulting from the rupture of the intracranial aneurysms in the past three decades. While developments in anesthesia and critical care management and recently introduced neuroprotective agents had a considerable effect on the improvement of the medical treatment strategies, advancements in the microsurgical techniques together with the evolvements in the field of interventional neuroradiology have improved surgical therapy. The aim of this paper is to review some of the recent advancements in the surgical and critical care management.

Abstract
Treatment of angiospasm as one of the most dangerous complications of subarachnoidal hemorrhage in the cerebral arterial aneurysm rupture constitutes an actual problem. Possibility of the cerebral vessels visualization have permitted to use intraarterial infusion of vasoactive preparations (IAIVAP) for treatment of angiospasm. Therapeutic efficacy for angiospasm, cerebral ischemia and edema depends on many factors and even in application of IAIVAP not always terminates successfully. The disease predictors studying makes possible to plan the intensive therapy tactics correctly, to prognosticate the disease course and the result of treatment. While analyzing the material there were used statistical methods of the data processing, permitting to reveal the prognostically meaningful criterions, influencing the treatment efficacy for angiospasm and its consequences. There was proved the influence of some predictors on the survival and mortality indexes, as well as on disablement and securing of ability to work in patients after application of IAIVAP. It was established, that conduction of IAIVAP had promoted the trustworthy raising of the survival indexes, as well as the lowering of mortality and the disablement rate in patients suffering angiospasm, cerebral ischemia and edema.

Abstract
Cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH) is a disease process for which the lack of effective treatments has plagued neurosurgeons for decades. Historically, successful treatment after SAH in the acute setting was often followed by a rapid, uncontrollable deterioration in the subacute interval. Little was known regarding the nature and progression of this condition until the mid-1800s, when the disease was first described by Gull. Insight into the origin and natural history of cerebral vasospasm came slowly over the next 100 years, until the 1950s. Over the past five decades our understanding of cerebral vasospasm has expanded exponentially. This newly discovered information has been used by neurosurgeons worldwide for successful treatment of complications associated with vasospasm. Nevertheless, although great strides have been made toward elucidating the causes of cerebral vasospasm, a lasting cure continues to elude experts and the disease continues to wreak havoc on patients after aneurysmal SAH.

Abstract
BACKGROUND AND PURPOSE The timing of aneurysmal surgery for patients presenting within the period at risk for vasospasm (VS) is controversial. The goal of this study is to review our experience of surgically treated patients in the presence of angiographic VS. MATERIALS AND METHODS From 1990-2004, 894 consecutive patients presented with an aneurysmal subarachnoid hemorrhage (SAH) and were treated with a policy of early surgery. We retrospectively analyzed the patients that had pre-operative angiographic VS. In this study, symptomatic VS was diagnosed when a decreased level of consciousness and/or focal deficit occurred after SAH in the presence of angiographic VS without confounding factors. Functional outcome was assessed three months after SAH using the Glasgow Outcome Scale. RESULTS Of the 40 patients studied, 62.5% were in good clinical grade Hunt & Hess (H&H 1-2) on admission; 25%, intermediate grade (H&H 3); 12.5%, poor grade (H&H 4-5). Surgery was performed 24 hours or less after initial angiography in 87.5% of patients and less than 48 hours in 97.5%. Pre-operative symptomatic VS was diagnosed in 25%. Post-operatively, angiographic VS was documented in 87.2%. Of the 30% of patients that presented post-operative symptomatic VS, 66.7% also demonstrated pre-operative symptomatic VS. The functional outcome was favorable in 92.5% of the studied patients. Two deaths occurred in patients presenting pre-operative early radiological and symptomatic VS. CONCLUSION Aneurysmal surgery, especially between 3-12 days following SAH, in the presence of asymptomatic pre-operative angiographic VS can be associated with a good outcome. Early surgery is not contra-indicated and might enable optimal treatment of VS.

Abstract
OBJECTIVE To identify the risk factors associated with symptomatic vasospasm after aneurysmal subarachnoid hemorrhage (SAH). METHODS The clinical data of 186 cases with SAH verified by radiology and lumbar puncture were reviewed retrospectively. RESULTS Fifty-five of the 186 patients (29.6%) developed symptomatic vasospasm. The incidence of symptomatic vasospasm was significantly higher in the patients of Fisher grade III than in those of Fisher grade I and Fisher grade II, in the patients in poor clinical status at admission the in those in better clinical status, and in the patients with repeated reoccurrence of SAH then in those without reoccurrence (all P < 0.01). Sex, age, treatment modality, and use of antifibrinolytic drugs (AFD) did not influence the development of symptomatic vasospasm (all P > 0.05). Multivariate analysis showed that Fisher grade III [odds ratio (OR) 2.549, 95% confidence interval (CI) 1.406 - 4.517], poor clinical status at admission (OR 2.342, 95% CI 1.320 - 4.159) and repeated reoccurrence of SAH (OR 2.492, 95% CI 1.394 approximately 4.448) were associated with the increased risk of symptomatic vasospasm. CONCLUSION Fisher grade III, poor clinical status at admission and repeated reoccurrence of SAH are significant independent risk factors of symptomatic vasospasm. The presence of symptomatic vasospasm can be independently predicted by the amount of subarachnoid hemorrhage, clinical status at admission, and times of SAH.

Abstract
Cerebral vasospasm is delayed narrowing of the large arteries of the circle of Willis occurring 4 to 14 days after aneurysmal subarachnoid hemorrhage (SAH). It is but one cause of delayed deterioration after SAH but, in general, is the most important potentially treatable cause of morbidity and mortality after SAH. Development of vasospasm is best predicted by the volume, location, persistence and density of subarachnoid clot early after SAH. Diagnosis is made by catheter angiography or, with less accuracy, by computed tomographic angiography, transcranial Doppler ultrasound or other methods. Treatment remains problematic because it is expensive, time-consuming, associated with substantial risk and largely ineffective. Treatment includes optimization of factors that affect cerebral blood flow and metabolism, systemic administration of nimodipine, hemodynamic therapy and pharmacologic and mechanical angioplasty.

Abstract
Cerebral vasospasm is still one of the leading causes of morbidity and mortality from subarachnoid hemorrhage. Vasospasm refractory to medical management can be treated with endovascular therapies, such as transluminal balloon angioplasty or infusion of intra-arterial vasodilating agents. In our review of clinical series reported in the English language literature, transluminal balloon angioplasty produced clinical improvement in 62% of patients, significantly improved mean transcranial Doppler (TCD) velocities(P <.05), significantly improved cerebral blood flow (CBF) in 85% of patients as studied by (133)Xenon techniques and serial single photon emission computerized tomography,and was associated with 5.0% complications and 1.1% vessel rupture. Intra-arterial papaverine therapy produced clinical improvement in 43% of patients but only transiently,requiring multiple treatment sessions (1.7 treatments per patient); significantly improved mean TCD velocities (P <.01) but only for less than 48 hours; improved CBF in 60% of patients but only for less than 12 hours; and was associated with increases in intracranial pressure and 9.9% complications. Intra-arterial nicardipine therapy produced clinical improvement in 42% of patients, significantly improved mean TCD velocities (P <.001) for 4 days, and was associated with no complications in our small series. We have adopted a treatment protocol at our institution of transluminal balloon angioplasty and intra-arterial nicardipine therapy as the endovascular treatments for medically refractory cerebral vasospasm.

Abstract
The effect of cervical spinal cord stimulation on the cerebral blood flow has been investigated both experimentally and clinically since 1986. Although the effect of the spinal cord stimulation on cerebral ischemia induced by cerebral vasospasm after subarachnoid hemorrhage has been investigated widely, neurological dysfunction induced by cerebral vasospasm and the effect of the spinal cord stimulation on neurological dysfunction have not been investigated so far. The aim of this study is to investigate the neurological dysfunction induced by cerebral vasospasm after subarachnoid hemorrhage and whether the spinal cord stimulation improves this neurological dysfunction or not in New Zealand albino rabbits. The animals were divided into sham and experiment groups: Sham group. Motor evoked potentials were recorded before experimental procedure was performed in this group. Just after, intracisternal saline was injected and 3 days later a stimulation electrode was placed in the cervical epidural space. Motor evoked potentials were recorded but electrical stimulation was not applied. Experiment group. Firstly, motor evoked potentials had been recorded before experimental procedure was performed in also this group. After then a stimulation electrode was placed in the cervical epidural space of the animals in which subarachnoid hemorrhage procedure was performed 3 days ago. Motor evoked potentials were recorded both before and after spinal cord stimulation. Motor evoked potential latencies and amplitudes did not change in the sham operation group. But, motor evoked potential latencies extended and the amplitudes decreased in the experiment group before spinal cord stimulation. Spinal cord stimulation improved the changes occurring in latencies and amplitudes in the experiment group. Spinal cord stimulation improves the neurological dysfunction induced by cerebral vasospasm and motor evoked potentials recording is a reliable electrophysiological method to detect cerebral vasospasm and to assess the effects of different treatments in cerebral vasospasm.

Abstract
Neurogenic pulmonary edema (NPE) is a well-known complication of acute brain injury. Neurogenic stunned myocardium (NSM) occurs clinically in a significant subset of patients with NPE. A 49-year-old woman developed refractory cerebral vasospasm requiring angioplasty following a subarachnoid hemorrhage. During angioplasty, NPE with NSM manifested as acute pulmonary edema associated with elevated pulmonary artery occlusion pressure and reduced cardiac output. Evaluations disclosed a right insular infarction, cardiac wall motion abnormalities, and electrocardiographic characteristics of NSM. The NSM completely resolved, and the neurological outcome was good. A 56-year-old woman developed NPE during complicated coil embolization of an internal carotid artery aneurysm. Cardiac function was normal, and the NPE resolved with a brief period of mechanical ventilation and diuresis. The delayed appearance of NSM and NPE during endovascular therapy in these patients implies a degree of risk for sympathetically mediated cardiopulmonary dysfunction during complex intracranial endovascular procedures.

Abstract
BACKGROUND Transluminal balloon angioplasty (TBA) has come into wide use for management of symptomatic cerebral vasospasm after subarachnoid hemorrhage (SAH). The long-term effects of TBA in this clinical context on cerebral blood flow (CBF) and the functional properties of the arterial wall after aneurysmal SAH remain controversial. We therefore studied these effects. METHODS All patients underwent unilateral TBA. Xenon-enhanced computed tomography was performed for an average of 18 days after TBA to measure CBF and cerebrovascular reactivity (CVR). Cerebral blood flow and CVR were compared between the side of TBA and the contralateral side. RESULTS Nineteen vascular territories were treated successfully with TBA in 12 patients. Angiographic improvement of vasospasm was demonstrated in all 12 patients, and 9 (75%) patients showed neurological improvement. After balloon angioplasty, global CBF was 35.1 +/- 8.2 mL/100 g per minute, with CBF on the side with TBA (37.8 +/- 10.3 mL/100 g per minute) being essentially the same as that on the other side (P = .0671, paired Student t test). Likewise, reactivity to acetazolamide did not differ significantly between sides (P = .0817). CONCLUSION Transluminal balloon angioplasty increased proximal vessel diameters but showed no significant influence on CBF or vascular reactivity 3 weeks later. Benefits presumably were short term, but the procedure was clinically safe.

Abstract
BACKGROUND Sphenopalatine ganglion stimulation dilates the ipsilateral arteries of the normal dog anterior circle of Willis. This experiment tested whether similar stimulation would reverse cerebral vasospasm. METHODS Six dogs underwent baseline angiography followed by creation of subarachnoid hemorrhage (SAH) by injection of autologous blood into the cisterna magna. Two days later, subarachnoid blood injection was repeated. Seven days later, angiography was repeated and the left sphenopalatine ganglion was exposed microsurgically. Angiography was repeated 15 minutes after exposure of the ganglion. The ganglion was then stimulated electrically 3 times and angiography repeated during, and 15 and 30 minutes after stimulation. The protocol was repeated again. Adequacy of stimulation was confirmed by the presence of immediate ipsilateral nasal mucus production. RESULTS Subarachnoid hemorrhage was associated with significant vasospasm of both middle cerebral arteries (11% +/- 4% and 18% +/- 7%, P < .05, paired t tests). Exposure of the ganglion and sham stimulation produced no substantial changes in arterial diameters compared with the diameter before stimulation and after ganglion exposure (n = 2-6 per measurement, paired t tests). Ganglion stimulation produced significant dilatation of the ipsilateral extracranial and intracranial internal carotid, middle cerebral, and anterior cerebral arteries compared with the contralateral arteries (13% +/- 6% to 32% +/- 14%, P < .05, paired t tests). CONCLUSIONS The mild to moderate vasospasm that results from SAH in dogs was reversed by sphenopalatine ganglion stimulation. Since this method carries a potential for human application, additional studies are warranted to determine the effects on more severe vasospasm.

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

Abstract
Endovascular treatment by balloon angioplasty or intra-arterial papaverine infusion has been established as a valuable treatment option in patients with cerebral vasospasm refractory to maximal medical therapy. A summary of the indications, applications and limitations is provided for microcatheter guided selective papaverine infusion and transluminal balloon angioplasty in patients who sustain cerebral vasospasm following subarachnoid haemorrhage. Structured neuro-intensive and endovascular treatment of imminent vasospasm integrate papaverine administration and balloon angioplasty as complimentary rather than alternative techniques.

Abstract
Abstract
OBJECTIVE:
Although several recent studies have suggested that the incidence of vasospasm after aneurysmal subarachnoid hemorrhage is lower in patients undergoing aneurysmal coiling as compared with clipping, other studies have had conflicting results. We reviewed our experience over 8 years and assessed whether clipping, craniotomy, or coiling affects patient outcomes or the risk for vasospasm.
METHODS:
We included 515 patients with aneurysmal subarachnoid hemorrhage, identified prospectively from November 2000 to February 2003 (243 patients) and retrospectively from November 1995 to October 2000 (272 patients), by using International Classification of Diseases, 9th Revision, codes for subarachnoid hemorrhage. We classified patients as follows: clipping (413 patients), coiling (79 patients), and craniotomy (436 patients, including all 413 patients who underwent clipping plus 23 who underwent coiling as well as craniotomy for various reasons). We studied four outcome measures: total vasospasm, symptomatic vasospasm, poor outcome (modified Rankin score 3–6), and in-hospital mortality. To assess the risk of total vasospasm and symptomatic vasospasm, we performed multivariate regression analyses adjusting for age, Fisher grade, Hunt and Hess grade, aneurysm location (anterior versus posterior circulation), and aneurysm treatment modality. To assess the risk for poor outcome and in-hospital mortality, we adjusted for all the above variables as well as for total and symptomatic vasospasm.
RESULTS:
In the clipping group there was 63% total vasospasm and 28% symptomatic vasospasm; in the coiling group there was 54% total vasospasm and 33% symptomatic vasospasm; and in the craniotomy group there was 64% total vasospasm and 28% symptomatic vasospasm. In the multivariate analysis, age <50 years (P = 0.0099) and Fisher Grade 3 (P < 0.00001) predicted total vasospasm, and Fisher Grade 3 (P < 0.000001) and Hunt and Hess Grade IV or V (P = 0.018) predicted symptomatic vasospasm. Predictors of poor outcome were age ≥50 years (P < 0.0001), Fisher Grade 3 (P = 0.0072), Hunt and Hess Grade IV or V (P < 0.00001), symptomatic vasospasm (P < 0.0001), and coiling (P = 0.0314 versus clipping and P = 0.045 versus craniotomy). Predictors of in-hospital mortality were age ≥ 50 years (P = 0.0030), Hunt and Hess Grade IV or V (P = 0.0001), symptomatic vasospasm (P < 0.00001), and coiling (P = 0.008 versus clipping and P = 0.0013 versus craniotomy). There was no significant difference in total vasospasm or symptomatic vasospasm when patients who underwent clipping or craniotomy were compared with patients who underwent coiling. In patients with Hunt and Hess Grade I to III (“good grade”), clipping and craniotomy were associated with better outcome and less in-hospital mortality, but there was no difference in total vasospasm or symptomatic vasospasm versus coiling. In patients with Hunt and Hess Grade IV or V (“poor grade”), there was no difference in any outcome measure among the treatment groups.
CONCLUSION:
In a single-center, retrospective, nonrandomized study, performance of clipping and/or craniotomy had significantly better outcome and lower mortality at discharge than coiling in good-grade patients but had no effect on total vasospasm or symptomatic vasospasm in good- or poor-grade patients.

Abstract
OBJECT Cerebral vasospasm after subarachnoid hemorrhage (SAH) continues to be a major source of morbidity in patients despite significant clinical and basic science research. Efforts to prevent vasospasm by removing spasmogens from the subarachnoid space have produced mixed results. The authors hypothesize that lumbar cisternal drainage can remove blood from the basal subarachnoid spaces more effectively than an external ventricular drain (EVD). This non-randomized, controlled-cohort study was undertaken to evaluate the effectiveness of a lumbar drain in patients with SAH compared with those in whom an EVD or no form of cerebrospinal fluid (CSF) drainage was used to prevent the development of clinical vasospasm and its sequelae. METHODS The authors collected data on 266 patients with nontraumatic SAH who were admitted to the University of Utah Health Sciences Center between January 1994 and January 2003. Of these, 167 met the study entry criteria. The treatment group consisted of 81 patients in whom a lumbar drain had been placed for CSF shunting, whereas the control group was composed of 86 patients who received no form of CSF drainage or who were treated solely with an EVD. Primary outcome measures were as follows: 1) clinically evident vasospasm; 2) the need for endovascular intervention; 3) vasospasm-induced infarction; 4) disposition at time of discharge; and 5) Glasgow Outcome Scale (GOS) score at 1 to 3 months postdischarge. Secondary outcomes included length of stay and the need for CSF shunting. The presence of a lumbar drain conferred a statistically significant protective and beneficial effect across all outcome measures, reducing the incidence of clinical vasospasm from 51 to 17%, the need for angioplasty from 45 to 17%, and the occurrence of vasospastic infarction from 27 to 7% (all p < or = 0.001-0.008). Patients in the treatment group were more likely to be discharged home (54% compared with 25%, p = 0.002) and to have a GOS score of 5 at follow up (71% compared with 35%, p < 0.001). The mean number of days spent in the intensive care unit and in the hospital overall was also fewer in the treatment group. A similar degree of benefit was found in patients with different Fisher grades and regardless of whether an EVD was needed on presentation, both by subgroup analysis and multivariate logistic regression modeling. There was no statistical difference between the groups in terms of patients requiring a shunt. Complications with lumbar drains were rare and yielded no permanent sequelae. CONCLUSIONS Shunting of CSF through a lumbar drain after an SAH markedly reduces the risk of clinically evident vasospasm and its sequelae, shortens hospital stay, and improves outcome. Its beneficial effects are probably mediated through the removal of spasmogens that exist in the CSF. The results of this study warrant a randomized clinical trial, which is currently under way.

Abstract
Radiographic cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) do not reflect cerebral hemodynamics and oxygenation and may occur in the absence of clinical deficit and vice-versa. This report is to describe preliminary findings in further development of a non invasive method to estimate regional cerebral oxygenation and perfusion. Measurements were performed with a technique combining near infrared spectroscopy (NIRS) and indocyaningreen (ICG) dye dilution. Successful data analysis has been performed based on the decomposition in pulsatile and non-pulsatile components of NIRS absorption data collected before and during the passage of ICG through the vascular bed under the NIRS-detector. First measurements in patients with CVS suggest that the technique could become a powerful tool in the detection and treatment of CVS. This non invasive technique can be done at the bedside, it seems to be safe, easy to perform and less time-consuming compared to conventional techniques. The influence of extracerebral bone and surface tissue on cerebral NIRS signal has not been clarified yet. Therefore a new subdural NIRS probe has been developed, which gives the opportunity to measure directly the concentration of the chromophores in the brain without the influence of extracerebral contamination. In future comparative measurements with conventional NIRS probes on the scalp will allow to quantify and eliminate extracerebral contamination from the NIRS signal.

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
OBJECTIVE The purpose of this study was to identify factors predictive of shunt-dependent hydrocephalus among patients with aneurysmal subarachnoid hemorrhage. The data can be used to predict which patients in this group have a high probability of requiring permanent cerebrospinal fluid diversion. METHODS Seven hundred eighteen patients with aneurysmal subarachnoid hemorrhage who were treated between 1990 and 1999 were retrospectively studied, to identify factors contributing to shunt-dependent hydrocephalus. With these data, a stepwise logistic regression procedure was used to determine the effect of each variable on the development of hydrocephalus and to create a scoring system. RESULTS Overall, 152 of the 718 patients (21.2%) underwent shunting procedures for treatment of hydrocephalus. Four hundred seventy-nine of the patients (66.7%) were female. Of the factors investigated, the following were associated with shunt-dependent hydrocephalus, as determined with a variety of statistical methods: 1) increasing age (P < 0.001), 2) female sex (P = 0.015), 3) poor admission Hunt and Hess grade (P < 0.001), 4) thick subarachnoid hemorrhage on admission computed tomographic scans (P < 0.001), 5) intraventricular hemorrhage (P < 0.001), 6) radiological hydrocephalus at the time of admission (P < 0.001), 7) distal posterior circulation location of the ruptured aneurysm (P = 0.046), 8) clinical vasospasm (P < 0.001), and 9) endovascular treatment (P = 0.013). The presence of intracerebral hematomas, giant aneurysms, or multiple aneurysms did not influence the development of shunt-dependent hydrocephalus. CONCLUSION The results of this study can help identify patients with a high risk of developing shunt-dependent hydrocephalus. This may help neurosurgeons expedite treatment, may decrease the cost and length of hospital stays, and may result in improved outcomes.

Abstract
BACKGROUND Transluminal balloon angioplasty (TBA) and intra-arterial papaverine (IAP) appear to be valuable alternatives for the treatment of aneurysmal subarachnoid hemorrhage (SAH)-induced vasospasm refractory to maximal medical therapy. Although widely used, guiding principles for the implementation of TBA and IAP are not yet established. Based on our retrospective analysis, we define guidelines for endovascular therapy for refractory vasospasm based on our clinical results, adverse effects, and pattern of vasospasm. METHODS Medical records of 62 patients who experienced aneurysmal SAH-induced vasospasm refractory to hypervolemic, hypertensive, hyperdynamic therapy, and who were treated with IAP or TBA were reviewed. Fifty patients met the inclusion criteria for analysis. After careful scrutiny, two types of responses to endovascular treatment were identified. On the basis of that grouping, patients were divided into two groups according to the number of arterial segments involved, that is, monoterritorial and multiterritorial vasospasm. Multiple variables were analyzed. RESULTS Patients undergoing multiple endovascular procedures exhibited the worst outcomes. Patients in the monoterritorial group experienced a higher incidence of clinical improvement and better outcomes after endovascular treatment. Elevated intracranial pressure (ICP) and ICP-related deaths were more prominent in the multiterritorial group of patients. Sustained ICP elevation after administration of IAP was strongly associated with poor outcome in the multiterritorial group. CONCLUSIONS IAP is indicated as an early potential single-dose infusion in distal monoterritorial vasospasm, if angioplasty is impossible or unsafe. The use of IAP in bilateral diffuse vasospasm is discouraged because of the high susceptibility of these patients to develop elevated ICP. Multiple IAP infusions seem to have no significant impact on patient outcome. Balloon angioplasty seems to be indicated at an early juncture in patients with multiterritorial proximal vasospasm.

Abstract
This report presents 74 consecutive cases of subarachnoid haemorrhage (SAH) in patients aged 70 years or older, compared with the 317 consecutive younger patients treated during the same period. An ultra-early surgical strategy for all SAH cases was used throughout the study period. Management outcome for all grades of elderly patients was independent in 38%, dependent in 14% and death in 49%. Surgical 3-month outcome of good grade elderly patients was independent 53%, dependent 19% and death 28%; and for poor grades was independent 35%, dependent 15% and death 50%. Elderly poor grade patients had similar outcome to younger patients, although good grade patients had better outcome in the younger group than the elderly group. Despite ultra-early surgery, rebleeding (<12 h of SAH) occurred in 9% of the elderly series. Aggressive, ultra-early treatment is likely to benefit elderly SAH patients, the potential benefit being greater for poor grade elderly patients.
