Abstract
BACKGROUND The ruptured anterior communicating artery aneurysm is the most frequent intra-cranial aneurysm treated at any neurosurgical department. These aneurysms arise from either the A1-A2-Acom artery junction or Acom artery. The surgical outcome depends on the age of the patient, time duration between ictus and surgery, and Hunt and Hess grade at admission. In this article, we intend to analyze the surgical outcome based on our proposed classification with our overall experience of Acom aneurysm. METHODS A retrospective review of our surgical database with 250 patients of ruptured Acom was done, and the location, morphology, and direction of aneurysm, along with other clinical parameters including the demographic profile, radiological findings, and intra-operative details, were studied. We classified the Acom based on both site of origin and morphology (Type I, junctional on the dominant side; Type II, fusiform with an ill-defined neck and branching pattern; Type III, saccular true Acom A) and secondarily as described in the literature on the basis of the direction of fundus (Type A-E). The clinical parameters were compared among the above groups using Fischer-exact and one-way analysis of variance test. RESULTS A total of 250 patients (M: F =113:137) were included (mean age 52.1 ± 11.5 standard deviation years). 55.2% patients had left A1 dominance. Type I Acom A was commonly found on the left dominant circulation (P = 0.00). The difference in aspect ratio of Type I (2.0 ± 0.8) and Type II (1.8 ± 0.52) aneurysms was insignificant (P = 0.28). However, a significant difference in post-operative vasospasm among different types of aneurysms was found (P < 0.05). The Type I Acom A were anteriorly directed, while Type II and III were posteriorly directed (P = 0.001). The mean follow-up of the study was 44.4 ± 25.7 months, with age (P = 0.007) and Hunt and Hess grade (P = 0.001) at admission correlating with surgical outcome. CONCLUSION Classifying the Acom A pre-operatively based on site and morphology, location, and direction of fundus helps in surgical planning and prognosis. The junctional 'Type IA aneurysms' are most common and possess a high intra-operative rupture rate. The anteriorly directed aneurysms have a better prognosis, and visual complaints are usually associated with anterior-inferiorly directed aneurysms.

Abstract
BACKGROUND This study explores racial and socioeconomic disparities in aneurysmal subarachnoid hemorrhage (aSAH) care, highlighting the impact on treatment and outcomes. The study aims to shed light on inequities and inform strategies for reducing disparities in healthcare delivery. METHODS In this cohort study the National Inpatient Sample database was queried for patient admissions with ruptured aSAH from 2016 to 2020. Multivariable analyses were performed estimating the impact of socioeconomic status and race on rates of acute treatment, functional outcomes, mortality, receipt of life-sustaining interventions (mechanical ventilation, tracheostomy, gastrostomy, and blood transfusions), and end-of-life care (palliative care and do not resuscitate). RESULTS A total of 181 530 patients were included. Minority patients were more likely to undergo treatment (OR 1.15, 95% CI 1.09 to 1.22, P<0.001) and were less likely to die (OR 0.89, 95% CI 0.84 to 0.95, P<0.001) than White patients. However, they were also more likely to have a tracheostomy (OR 1.47, 95% CI 1.33 to 1.62, P<0.001) and gastrostomy tube placement (OR 1.43, 95%CI 1.32 to 1.54, P<0.001), while receiving less palliative care (OR 0.75, 95% CI 0.70 to 0.80, P<0.001). This trend persisted when comparing minority patients from wealthier backgrounds with White patients from poorer backgrounds for treatment (OR 1.10, 95% CI 1.00 to 1.21, P=0.046), mortality (OR 0.82, 95% CI 0.74 to 0.89, P<0.001), tracheostomy tube (OR 1.27, 95% CI 1.07 to 1.48, P<0.001), gastrostomy tube (OR 1.34, 95% CI 1.18 to 1.52, P<0.001), and palliative care (OR 0.76, 95% CI 0.69 to 0.84, P<0.001). CONCLUSIONS Compared with White patients, minority patients with aSAH are more likely to undergo acute treatment and have lower mortality, yet receive more life-sustaining interventions and less palliation, even in higher socioeconomic classes. Addressing these disparities is imperative to ensure equitable access to optimal care and improve outcomes for all patients regardless of race or class.

Abstract
Abstract
Background The initial clinical status after aneurysm rupture, whether primary or secondary, determines the final outcome. The most common cause of patient deterioration is a high Hunt and Hess (HH) score, which correlates closely with a high mortality rate. Poor-grade aneurysmal subarachnoid hemorrhage (SAH) is determined as an HH score 4 or 5. The aim of this study was to evaluate the clinical characteristics of poor graded aneurysmal SAH at our institution.
Patients and Methods During the 5-year period, 415 patients with intracranial aneurysm were admitted to our institution. Patients with poor-grade aneurysmal SAH accounted 31.08% (n = 132) of the total number of ruptured aneurysms. Interventional treatment was predominantly in the form of surgery, whereas conservative treatment included medication and external ventricular drainage. Final outcome was assessed with a modified Rankin score (mRs). Statistical analysis was performed using SPSS version 23.0 with a significance level set to 5% (α = 0.05).
Results The majority of patients (57.6%) were in the age range from 51 to 69 years. Twenty-five patients (18.9%) had an HH score of 4, whereas 107 patients (81.1%) had an HH score of 5. Depending on the location, the majority of patients (n = 43) had an aneurysm on the medial cerebral artery (MCA). The final aneurysm occlusion was performed in 71 patients, of whom 94.36% were treated surgically. A positive outcome (mRs 0–4) was found in 49.25% of patients who underwent primarily surgical, treatment with a mortality of 42.3%. Although the outcome was better in patients with an HH score 4, both groups benefited from surgical treatment.
Conclusion Poor-grade aneurismal SAH is a condition of the middle and older age, with most patients with an HH 5 score and deep comatose state. There was better outcome in patients with an HH score of 4 compared to an HH score of 5 and both groups benefited from surgical treatment, which resulted in a positive outcome in almost 50% of surgically treated patients.

Abstract
Subarachnoid haemorrhage (SAH) is the third most common subtype of stroke. Incidence has decreased over past decades, possibly in part related to lifestyle changes such as smoking cessation and management of hypertension. Approximately a quarter of patients with SAH die before hospital admission; overall outcomes are improved in those admitted to hospital, but with elevated risk of long-term neuropsychiatric sequelae such as depression. The disease continues to have a major public health impact as the mean age of onset is in the mid-fifties, leading to many years of reduced quality of life. The clinical presentation varies, but severe, sudden onset of headache is the most common symptom, variably associated with meningismus, transient or prolonged unconsciousness, and focal neurological deficits including cranial nerve palsies and paresis. Diagnosis is made by CT scan of the head possibly followed by lumbar puncture. Aneurysms are commonly the underlying vascular cause of spontaneous SAH and are diagnosed by angiography. Emergent therapeutic interventions are focused on decreasing the risk of rebleeding (ie, preventing hypertension and correcting coagulopathies) and, most crucially, early aneurysm treatment using coil embolisation or clipping. Management of the disease is best delivered in specialised intensive care units and high-volume centres by a multidisciplinary team. Increasingly, early brain injury presenting as global cerebral oedema is recognised as a potential treatment target but, currently, disease management is largely focused on addressing secondary complications such as hydrocephalus, delayed cerebral ischaemia related to microvascular dysfunction and large vessel vasospasm, and medical complications such as stunned myocardium and hospital acquired infections.

Abstract
Recently, many studies have shown that microRNAs (miRNAs) in extracellular bioliquids are strongly associated with subarachnoid hemorrhage (SAH) and its complications. The article presents issues related to the occurrence of subarachnoid hemorrhage (epidemiology, symptoms, differential diagnosis, examination, and treatment of the patient) and a review of current research on the correlation between miRNAs and the complications of SAH. The potential use of miRNAs as biomarkers in the treatment of SAH is presented.

Abstract
BACKGROUND There are few large population-based studies of outcomes after subarachnoid hemorrhage (SAH) than other stroke types. METHODS We pooled data from 13 population-based stroke incidence studies (10 studies from the INternational STRroke oUtComes sTudy (INSTRUCT) and 3 new studies; N=657). Primary outcomes were case-fatality and functional outcome (modified Rankin scale score 3-5 [poor] vs. 0-2 [good]). Harmonized patient-level factors included age, sex, health behaviours (e.g. current smoking at baseline), comorbidities (e.g.history of hypertension), baseline stroke severity (e.g. NIHSS >7) and year of stroke. We estimated predictors of case-fatality and functional outcome using Poisson regression and generalized estimating equations using log-binomial models respectively at multiple timepoints. RESULTS Case-fatality rate was 33% at 1 month, 43% at 1 year, and 47% at 5 years. Poor functional outcome was present in 27% of survivors at 1 month and 15% at 1 year. In multivariable analysis, predictors of death at 1-month were age (per decade increase MRR 1.14 [1.07-1.22]) and SAH severity (MRR 1.87 [1.50-2.33]); at 1 year were age (MRR 1.53 [1.34-1.56]), current smoking (MRR 1.82 [1.20-2.72]) and SAH severity (MRR 3.00 [2.06-4.33]) and; at 5 years were age (MRR 1.63 [1.45-1.84]), current smoking (MRR 2.29 [1.54-3.46]) and severity of SAH (MRR 2.10 [1.44-3.05]). Predictors of poor functional outcome at 1 month were age (per decade increase RR 1.32 [1.11-1.56]) and SAH severity (RR 1.85 [1.06-3.23]), and SAH severity (RR 7.09 [3.17-15.85]) at 1 year. CONCLUSION Although age is a non-modifiable risk factor for poor outcomes after SAH, however, severity of SAH and smoking are potential targets to improve the outcomes.

Corticothalamic Connectivity in Aneurysmal Subarachnoid Hemorrhage: Relationship with Disordered Consciousness and Clinical Outcomes. Neurocrit Care 2021; 36:760-771. [PMID: 34669180 DOI: 10.1007/s12028-021-01354-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 09/10/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND We present an exploratory analysis of the occurrence of early corticothalamic connectivity disruption after aneurysmal subarachnoid hemorrhage (SAH) and its correlation with clinical outcomes. METHODS We conducted a retrospective study of patients with acute SAH who underwent continuous electroencephalography (EEG) for impairment of consciousness. Only patients undergoing endovascular aneurysm treatment were included. Continuous EEG tracings were reviewed to obtain artifact-free segments. Power spectral analyses were performed, and segments were classified as A (only delta power), B (predominant delta and theta), C (predominant theta and beta), or D (predominant alpha and beta). Each incremental category from A to D implies greater preservation of corticothalamic connectivity. We dichotomized categories as AB for poor connectivity and CD for good connectivity. The modified Rankin Scale score at follow-up and in-hospital mortality were used as outcome measures. RESULTS Sixty-nine patients were included, of whom 58 had good quality EEG segments for classification: 28 were AB and 30 were CD. Hunt and Hess and World Federation of Neurological Surgeons grades were higher and the initial Glasgow Coma Scale score was lower in the AB group compared with the CD group. AB classification was associated with an adjusted odds ratio of 5.71 (95% confidence interval 1.61-20.30; p < 0.01) for poor outcome (modified Rankin Scale score 4-6) at a median follow-up of 4 months (interquartile range 2-6) and an odds ratio of 5.6 (95% confidence interval 0.98-31.95; p = 0.03) for in-hospital mortality, compared with CD. CONCLUSIONS EEG spectral-power-based classification demonstrates early corticothalamic connectivity disruption following aneurysmal SAH and may be a mechanism involved in early brain injury. Furthermore, the extent of this disruption appears to be associated with functional outcome and in-hospital mortality in patients with aneurysmal SAH and appears to be a potentially useful predictive tool that must be validated prospectively.

Abstract
PURPOSE OF REVIEW Aneurysmal subarachnoid hemorrhage remains a devastating disease process despite medical advances made over the past 3 decades. Much of the focus was on prevention and treatment of vasospasm to reduce delayed cerebral ischemia and improve outcome. In recent years, there has been a shift of focus onto early brain injury as the precursor to delayed cerebral ischemia. This review will focus on the most recent data surrounding the pathophysiology of aneurysmal subarachnoid hemorrhage and current management strategies. RECENT FINDINGS There is a paucity of successful trials in the management of subarachnoid hemorrhage likely related to the targeting of vasospasm. Pathophysiological changes occurring at the time of aneurysmal rupture lead to early brain injury including cerebral edema, inflammation, and spreading depolarization. These events result in microvascular collapse, vasospasm, and ultimately delayed cerebral ischemia. Management of aneurysmal subarachnoid hemorrhage has remained the same over the past few decades. No recent trials have resulted in new treatments. However, our understanding of the pathophysiology is rapidly expanding and will advise future therapeutic targets.

Abstract
OBJECTIVE Blood blister aneurysms are small, thin-walled, rapidly growing side-wall aneurysms that have proved particularly difficult to treat, and evidence-based guidance for treatment strategies is lacking. A systematic review and meta-analysis was performed to aggregate the available data and compare the 3 primary treatment modalities. METHODS We performed a comprehensive literature search according to PRISMA guidelines followed by an indirect meta-analysis that compares the safety and efficacy of surgical, flow-diverting stents (FDS), and other endovascular approaches for the treatment of ruptured blood blister aneurysms. RESULTS A total of 102 studies were included for quantitative synthesis, with sample sizes of 687 treated surgically, 704 treated endovascularly without FDS, and 125 treated via flow diversion. Comparatively, FDS achieved significantly reduced rates of perioperative retreatment compared with both surgical (P = 0.025) and non-FDS endovascular (P < 0.001). The FDS subgroup also achieved a significantly lower incidence of perioperative rebleed (P < 0.001), perioperative hydrocephalus (P = 0.012), postoperative infarction (P = 0.002), postoperative hydrocephalus (P < 0.001), and postoperative vasospasm (P = 0.002) compared with those patients in the open surgical subgroup. Although no significant differences were found among groups on the basis of functional outcomes, angiographic outcomes detailed by rates of radiographic complete occlusion were highest for surgical (90.7%, 262/289) and FDS (89.1%, 98/110) subgroups versus the non-FDS endovascular subgroup (82.7%, 268/324). CONCLUSIONS Flow diversion seems to be an effective treatment strategy for ruptured blood blister aneurysms, with lower rates of perioperative complications compared with surgical and other endovascular techniques, but studies investigating long-term outcomes after flow diversion warrant further study.

Abstract
Background Comparative studies between standard pterional and supraorbital keyhole approaches for aneurysms had potential biases with the heterogeneity of patient selection, differences among surgeons, or varying expertise across the surgeon's learning curve. This is a study of a surgeon's transition from pterional to keyhole approach for early clipping of selected consecutive ruptured anterior circulation aneurysms. Methods Patients more than 18 years, presenting within 72 hours of ictus, in good clinical grades 1 to 3, no midline shift, with saccular aneurysms less than 25 mm at either communicating segment of internal carotid artery, anterior communicating artery, or middle cerebral artery segment till bifurcation were studied between the last 25 cases of pterional and first 25 cases of the keyhole, for the intraoperative and postoperative surgical outcome parameters. Results There was no significant difference among baseline parameters, including the location of aneurysms across both groups. While only four cases of pterional had an intraoperative ventricular puncture, the lumbar drain was electively inserted in all keyhole patients. The intraoperative parameters, such as a dural tear, adequate parent vessel exposure, temporary clipping, and intraoperative rupture, did not show any significant difference. None had immediate postoperative deficits. While delayed cerebral ischemia and wound complaints were similar in both groups, temporal hollowing and chewing difficulty were significantly more in pterional patients( p = 0.01). Conclusion A surgeon experienced in pterional approach can comfortably and safely shift to the keyhole for early clipping of selected ruptured aneurysms less than 25 mm, with a comparable surgical outcome but better cosmesis and mastication.

Abstract
Background The classical eyebrow supraorbital keyhole craniotomy has limited working volume due to the thick incurving of the frontal bone necessitating generous drilling of the frontal base. However, the basal variant with sectioning of the orbital rim results in increased periorbital edema. Objective We describe a novel orbital rim sparing single-piece fronto-orbital keyhole approach, probably the first such report with a comparative review of relevant literature. Methods Following eyebrow incision, bidirectional drilling with a ball tip behind the fronto-zygomatic suture exposes the periorbita and frontal dura, with orbital roof in-between. The craniotomy is fashioned with an angled fronto-orbital cut parallel to and sparing the orbital rim with dura-guard over the periorbita, a frontal cut over the dura, and an optional cut along the lateral orbital roof from within the burr hole. A comparative review of this technique with traditional methods is also carried out. Results Compared to the classical supraorbital keyhole, this minimally invasive approach yields a wider basal exposure with greater working volume for intracranial and orbital lesions. Compared to the basal variant of keyhole fronto-orbital approach, this technique results in the least disturbance to periorbita's attachment with the orbital margin, maintenance of orbital contour, better cosmesis with use of simple tools and self-fitting flap. Conclusion The orbital rim sparing single-piece fronto-orbital keyhole craniotomy is an easy and novel minimally invasive approach with greater working volume without the disadvantages of sectioning the orbital rim.

Abstract
Background Neurological outcome and mortality of patients suffering from poor grade subarachnoid hemorrhage (SAH) may have changed over time. Several factors, including patients’ characteristics, the presence of hydrocephalus and intraparenchymal hematoma, might also contribute to this effect. The aim of this study was to assess the temporal changes in mortality and neurologic outcome in SAH patients and identify their predictors. Methods We performed a single center retrospective cohort study from 2004 to 2018. All non-traumatic SAH patients with poor grade on admission (WFNS score of 4 or 5) who remained at least 24 h in the hospital were included. Time course was analyzed into four groups according to the years of admission (2004–2007; 2008–2011; 2012–2015 and 2016–2018). Results A total of 353 patients were included in this study: 202 patients died (57 %) and 260 (74 %) had unfavorable neurological outcome (UO) at 3 months. Mortality tended to decrease in in 2008–2011 and 2016–2018 periods (HR 0.55 [0.34–0.89] and HR 0.33 [0.20–0.53], respectively, when compared to 2004–2007). The proportion of patients with UO remained high and did not vary significantly over time. Patients with WFNS 5 had higher mortality (68 % vs. 34 %, p = 0.001) and more frequent UO (83 % vs. 54 %, p = 0.001) than those with WFNS 4. In the multivariable analysis, WFNS 5 was independently associated with mortality (HR 2.12 [1.43–3.14]) and UO (OR 3.23 [1.67–6.25]). The presence of hydrocephalus was associated with a lower risk of mortality (HR 0.60 [0.43–0.84]). Conclusions Both hospital mortality and UO remained high in poor grade SAH patients. Patients with WFNS 5 on admission had worse prognosis than others; this should be taken into consideration for future clinical studies.

Abstract
BACKGROUND The COVID19 lockdown has altered the dynamics of living. Its collateral fallout on head injury care has not been studied in detail, especially from low- and middle-income countries, possibly overwhelmed more than developed nations. Here, we analyze the effects of COVID19 restrictions on head injury patients in a high-volume Indian referral trauma center. METHODS From the prospective trauma registry, clinico-epidemiological and radiological parameters of patients managed during 190 days before and 190 days during COVID19 phases were studied. As an indicator of care, the inpatient mortality of patients with severe HI was also compared with appropriate statistical analyses. RESULTS Of the total 3372 patients, there were 83 head injury admissions per week before COVID19 restrictions, which decreased to 33 every week (60% drop) during the lock phases and stabilized at 46 per week during the unlock phases. COVID19 restrictions caused a significant increase in the proportion of patients arriving directly without resuscitation at peripheral centers and later than 6 h of injury. Though the most common mechanism was vehicular, a relative increase in the proportion of assaults was noted during COVID19. There was no change in the distribution of mild, moderate, and severe injuries. Despite a decrease in the percentage of patients with systemic illnesses, severe head injury mortality was significantly more during the lock phases than before COVID19 (59% vs. 47%, p = 0.02). CONCLUSIONS COVID19 restrictions have amplified the already delayed admission among patients of head injury from north-west India. The severe head injury mortality was significantly greater during lock phases than before COVID19, highlighting the collateral fallout of lockdown. Pandemic control measures in the future should not ignore the concerns of trauma emergency care.

Abstract
Background: Neurosurgical patients with stroke, trauma, and brain tumors can be among the victims of the COVID-19 pandemic in developing countries, which need to be managed efficiently. Methods: This is an overview of neurosurgical nurses’ challenges and strategies in the current COVID-19 pandemic environment in developing countries. Results: Here, we reviewed the unique challenges of providing neurosurgical nursing services during the COVID-19 pandemic in developing countries. We address specific issues such as transferring neurosurgical patients, allocating medical supplies, prioritizing neurosurgical services, COVID-19 testing protocols, and patient triage (emergent vs. urgent vs. delayed surgery). Teleconsultation, telenursing services for outpatient treatment, follow-up and virtual teaching strategies associated with neurosurgical nursing are discussed. Conclusion: Neurosurgical nursing during the COVID-19 pandemic in developing countries requires transparent planning, implementation, and careful consideration of various telemedicine strategies.

Abstract
OBJECTIVECOVID-19 has affected surgical practice globally. Treating neurosurgical patients with the restrictions imposed by the pandemic is challenging in institutions with shared patient areas. The present study was performed to assess the changing patterns of neurosurgical cases, the efficacy of repeated testing before surgery, and the prevalence of COVID-19 in asymptomatic neurosurgical inpatients.METHODSCases of non–trauma-related neurosurgical patients treated at the Postgraduate Institute of Medical Education and Research (PGIMER) before and during the COVID-19 pandemic were reviewed. During the pandemic, all patients underwent a nasopharyngeal swab reverse transcription–polymerase chain reaction test to detect COVID-19 at admission. Patients who needed immediate intervention were surgically treated following a single COVID-19 test, while stable patients who initially tested negative for COVID-19 were subjected to repeated testing at least 5 days after the first test and within 48 hours prior to the planned surgery. The COVID-19 positivity rate was compared with the local period prevalence. The number of patients who tested positive at the second test, following a negative first test, was used to determine the probable number of people who could have become infected during the surgical procedure without second testing.RESULTSOf the total 1769 non–trauma-related neurosurgical patients included in this study, a mean of 337.2 patients underwent surgery per month before COVID-19, while a mean of 184.2 patients (54.6% of pre–COVID-19 capacity) underwent surgery per month during the pandemic period, when COVID-19 cases were on the rise in India. There was a significant increase in the proportion of patients undergoing surgery for a ruptured aneurysm, stroke, hydrocephalus, and cerebellar tumors, while the number of patients seeking surgery for chronic benign diseases declined. At the first COVID-19 test, 4 patients (0.48%) tested were found to have the disease, a proportion 3.7 times greater than that found in the local community. An additional 5 patients tested positive at the time of the second COVID-19 test, resulting in an overall inpatient period prevalence of 1%, in contrast to a 0.2% national cumulative caseload. It is possible that COVID-19 was prevented in approximately 67.4 people every month by using double testing.CONCLUSIONSCOVID-19 has changed the pattern of neurosurgical procedures, with acute cases dominating the practice. Despite the fact that the pandemic has not yet reached its peak in India, COVID-19 has been detected 3.7 times more often in asymptomatic neurosurgical inpatients than in the local community, even with single testing. Double testing displays an incremental value by disclosing COVID-19 overall in 1 in 100 inpatients and thus averting its spread through neurosurgical services.

Differential independent impact of the intraoperative use of navigation and angled endoscopes on the surgical outcome of endonasal endoscopy for pituitary tumors: a prospective study. Neurosurg Rev 2020; 44:2291-2298. [PMID: 33089448 DOI: 10.1007/s10143-020-01416-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 08/26/2020] [Accepted: 10/07/2020] [Indexed: 02/07/2023]
Abstract
Despite widespread popularity of navigation and angled endoscopes in endonasal endoscopy, there are hardly few studies on their efficacy with the extent of resection or retreatment. This is probably the first study to assess the independent impact of these adjuncts among pituitary tumors. Patients with pituitary tumors undergoing endonasal endoscopy were prospectively studied for their demographics, clinico-radiological features, intraoperative use of navigation, and angled endoscopes, in relation to gross total resection (GTR), near total resection (NTR), endocrine remission, and retreatment. Pertinent statistical analyses were performed. Among a total of 139 patients, navigation and angled endoscopes could be used in 54 and 48 patients, respectively, depending upon their availability rather than chosen as per the case. There was no significant difference in baseline characteristics in relation to their use. The surgeon's perception of immediate benefit was noted among 51.9% while using navigation. The use of angled endoscopes towards the end of resection could help with additional tumor removal in 62.5% of patients. Overall, the use of navigation resulted in a significantly higher GTR (80.8% vs. 59.7%, OR 2.83, p = 0.01), a higher GTR/NTR (86.5% vs. 70.8%, OR 2.65, p = 0.04), and a lower retreatment rate (7.7% vs. 20.8%, OR 3.15, p = 0.05) than the others. In functioning tumors with cavernous sinus invasion, navigation had significantly increased remission rates (69.2% vs. 0%, p = 0.03). The use of angled endoscopes yielded a significantly higher GTR/NTR (91.7% vs. 70.6%, p = 0.04) and a lower retreatment rate (0% vs. 15.7%, p = 0.05) among only non-functioning adenomas. In multivariate analyses, the use of neuronavigation had a significant association with both GTR and retreatment rates (p values 0.005 and 0.02 respectively), independent of other confounding factors. The elective intraoperative use of navigation has a significant independent impact on the extent of resection and retreatment overall. While navigation results in better remission rates among functioning tumors with cavernous sinus invasion, angled endoscopy has a significant association with surgical outcomes in non-functioning tumors.

Abstract
Background: Spontaneous subarachnoid hemorrhage (SAH) is one of the significant etiologies for stroke. SAH causes higher morbidity and mortality with loss of productivity, resulting in increased disease burden. Only few studies in Qatar have reported on SAH, and the epidemiological features of SAH and aneurysmal SAH (aSAH) have not been comprehensively studied before in Qatar. Our study aimed to describe the epidemiological profile of patients with SAH and aSAH in the State of Qatar. Methods: We reviewed the medical records of all patients with SAH and/or ruptured aneurysm who were consecutively admitted to Hamad General Hospital (600-bed tertiary care facility) from January 1, 2007 to December 31, 2016. We performed a quantitative analysis of demographics, clinical characteristics, diagnostic findings, interventions, and overall mortality. We used SPSS version 18 for data entry. We used chi-square and student t tests to compare the groups. We considered p < 0.05 as statistically significant. Results: The study included 323 patients with aneurysmal and non-aneurysmal SAH. The mean age at presentation was 47.4 ± 12.2 years. Men comprised 68.7% of the cases. Further, 86.6% of the patients presented with acute-onset headache. Additionally, 217 patients had 1 aneurysm, and 32 patients had multiple aneurysms. Anterior communicating artery aneurysm has been found to be the most common aneurysm. Non-aneurysmal SAH occurred in 74 patients (22.9%), with male predominance. Moreover, 23.7% and 52.6% of the patients underwent microsurgical clipping and coiling of the aneurysm, respectively. The overall mortality in World Federation of Neurosurgeon Score (WFNS) grades 1 and 2 SAH was lesser than that in higher grades (28.6% vs 71.4%). Of 323 patients, 69 died within 1 month post-ictus, accounting for an overall mortality rate of 21.2% in our study. Conclusions: The annual incidence of aneurysmal SAH in Qatar has been increasing. Men had a higher incidence of aSAH. Internal carotid aneurysms have been found to be more common in Qatari women, which may have a genetic basis. Lower WFNS grades of aSAH have been associated with better prognosis. The overall mortality associated with aSAH in Qatar has declined over the last 3 years.

Abstract
Subarachnoid hemorrhage (SAH) frequently arises after an aneurysm in a cerebral artery ruptures, resulting into bleeding as well as clot formation. High-mobility group box 1 (HMGB1) is an extremely preserved, universal protein secreted in the nuclei of all cell varieties. This review explores the biomarker as well as therapeutic potentials of HMBG1 in SAH especially during the occurrence of cerebral vasospasms. Plasma HMGB1 levels have proven to be very useful prognosticators of effective outcome as well as death after SAH. Correspondingly, higher HMGB1 levels in the cerebrospinal fluid (CSF) of SAH patients correlated well with poor outcome; signifying that, CSF level of HMGB1 is a novel predictor of outcome following SAH. Nonetheless, the degree of angiographic vasospasm does not always correlate with the degree of neurological deficits in SAH patients. HMGB1 stimulated cerebral vasospasm, augmented gene as well as protein secretory levels of receptor for advance glycation end product (RAGE) in neurons following SAH; which means that, silencing HMGB1 during SAH could be of therapeutic value. Compounds like resveratrol, glycyrrhizin, rhinacanthin, purpurogallin, 4′-O-β-D-Glucosyl-5-O-Methylvisamminol (4OGOMV) as well as receptor-interacting serine/threonine-protein kinase 3 (RIPK3) gene are capable of interacting with HMGB1 resulting in therapeutic benefits following SAH.
