RESUMO
BACKGROUND: Middle meningeal artery (MMA) embolization has been increasingly applied in adult populations for the treatment of chronic subdural hematomas (cSDH). There is a paucity of literature on the indications, safety, and outcomes of MMA embolization in the pediatric population. SUMMARY: A systematic literature review on pediatric patients undergoing MMA embolization was performed. We also report the case of successful bilateral MMA embolization for persistent subdural hematomas following resection of a juvenile pilocytic astrocytoma. Persistent bilateral subdural hematomas following resection of a large brain tumor resolved following MMA embolization in a 13-year-old male. Indications for MMA embolization in the pediatric literature included cSDH (6/13, 46.2%), treatment or preoperative embolization of arteriovenous fistula or arteriovenous malformation (3/13, 23.1%), preoperative embolization for tumor resection (1/13, 7.7%), or treatment of acute epidural hematoma (1/13, 7.7%). Embolic agents included microspheres or microparticles (2/13, 15.4%), Onyx (3/13, 23.1%), NBCA (3/13, 23.1%), or coils (4/13, 30.8%). KEY MESSAGES: Whereas MMA embolization has primarily been applied in the adult population for subdural hematoma in the setting of cardiac disease and anticoagulant use, we present a novel application of MMA embolization in the management of persistent subdural hematoma following resection of a large space-occupying lesion. A systematic review of MMA embolization in pediatric patients currently shows efficacy; a multi-institutional study is warranted to further refine indications, timing, and safety of the procedure.

BACKGROUND: Evidence regarding the utilization and outcomes of endovascular thrombectomy (EVT) for pediatric ischemic stroke is limited, and justification for its use is largely based on extrapolation from clinical benefits observed in adults. METHODS: Weighted discharge data from the National Inpatient Sample were queried to identify pediatric patients with ischemic stroke (<18 years old) during the period of 2010 to 2019. Complex samples statistical methods were used to characterize the profiles and clinical outcomes of EVT-treated patients. Propensity adjustment was performed to address confounding by indication for EVT based on disparities in baseline characteristics between EVT-treated patients and those medically managed. RESULTS: Among 7365 pediatric patients with ischemic stroke identified, 190 (2.6%) were treated with EVT. Utilization significantly increased in the post-EVT clinical trial era (2016-2019; 1.7% versus 4.0%; P<0.001), while the use of decompressive hemicraniectomy decreased (2.8% versus 0.7%; P<0.001). On unadjusted analysis, 105 (55.3%) EVT-treated patients achieved favorable functional outcomes at discharge (home or to acute rehabilitation), while no periprocedural iatrogenic complications or instances of contrast-induced kidney injury were reported. Following propensity adjustment, EVT-treated patients demonstrated higher absolute but nonsignificant rates of favorable functional outcomes in comparison with medically managed patients (55.3% versus 52.8%; P=0.830; adjusted hazard ratio, 1.01 [95% CI, 0.51-2.03]; P=0.972 for unfavorable outcome). Among patients with baseline National Institutes of Health Stroke Scale score >11 (75th percentile of scores in cohort), EVT-treated patients trended toward higher rates of favorable functional outcomes compared with those treated medically only (71.4% versus 55.6%; P=0.146). In a subcohort assessment of EVT-treated patients, those administered preceding thrombolytic therapy (n=79, 41.6%) trended toward higher rates of favorable functional outcomes (63.3% versus 49.5%; P=0.060). CONCLUSIONS: This cross-sectional evaluation of the clinical course and short-term outcomes of pediatric patients with ischemic stroke treated with EVT demonstrates that EVT is likely a safe modality which confers high rates of favorable functional outcomes.

The aim of this study was to review and analyze the neurosurgery body of literature to document the current knowledge of frailty within neurosurgery, standardizing terminology and how frailty is defined, including the different levels of frailty, while determining what conclusions can be drawn about frailty's impact on neurosurgical outcomes. While multiple studies on frailty in neurosurgery exist, no literature reviews have been conducted. Therefore, we performed a literature review in order to organize, tabulate, and present findings from the data to broaden the understanding about what we know from frailty and neurosurgery. We performed a PubMed search to identify studies that evaluated frailty and neurosurgery. The terms "frail," "frailty," "neurosurgery," "spine surgery," "craniotomy," and "neurological surgery" were all used in the query. We then organized, analyzed, and summarized the comprehensive frailty and neurosurgical literature. The literature contained 25 published studies analyzing frailty in neurosurgery between December 2015 and December 2018. Five of these studies were cranial neurosurgical studies, the remaining studies focused on spinal neurosurgery. Over 100,000 surgical cases were analyzed among the 25 studies. Of these, 18 studies demonstrated that increasing frailty was associated with increased rate of complications, 10 studies showed that frailty was associated with higher mortality rates, 11 studies demonstrated an association between frailty and increased hospital length of stay, and 5 studies noted that higher frailty was associated with discharge to a higher level of care. The current body of literature repeatedly demonstrates that frailty is associated with worse outcomes across the neurosurgical subspecialties.

BACKGROUND AND PURPOSE: While patients with angiogram-negative subarachnoid hemorrhages (ANSAH) have better prognoses than those with aneurysmal SAH, frailty's impact on outcomes in ANSAH is unclear. We previously showed that the modified frailty index (mFI-11) is associated with poor outcomes following ANSAH. Here, we compared the mFI-5, mFI-11, Charlson Comorbidity Index (CCI), and temporalis thickness (TMT) to determine which index was the best predictor of ANSAH outcomes and mortality rates. METHODS: In this retrospective cohort analysis between 2014 and 2018, patients with non-traumatic, angiogram negative SAH (ANSAH) were identified. The admission mFI-5, mFI-11, CCI, and TMT were calculated for each patient. Primary outcomes were mortality rate, discharge location, and prolonged length of stay (PLOS; LOS >85th percentile). Multivariate logistic regression and receiver operating characteristic (ROC) curves were used to evaluate frailty as predictors of primary endpoints. RESULTS: We included 75 patients with a mean age of 55.4 ± 1.5 years. There were 4 patient deaths (5.3%), 53 patients (70.7%) discharged home, and 11 patients (14.7%) with PLOS. On ROC analysis, the mFI-5 had the highest discriminatory value for mortality (AUC = 0.97) while the mFI-11 was most discriminatory for discharge home (AUC = 0.85) and PLOS (AUC = 0.78). On multivariate analysis, the only independent predictor of mortality was the mFI-11 (OR = 0.46; 95%CI: 1.45-14.23; p = 0.009) while the mFI-5 was the best predictor of discharge home (OR = 0.21; 95% CI: 0.08-0.61; p = 0.004). On multivariate analysis, the only independent predictor of PLOS was the Hunt and Hess score (OR = 2.63; 95%CI: 1.38-5.00; p = 0.003). The CCI and TMT were inferior to either mFI for predicting primary endpoints. CONCLUSIONS: Increasing frailty is associated with poorer outcomes and higher mortality following ANSAH. The mFI-5 and mFI-11 were found to be superior predictors of discharge home and mortality rate. While larger prospective study is needed, frailty, as measured by mFI-11 and -5, should be considered when evaluating ANSAH prognosis.

INTRODUCTION: Flow diversion of the distal anterior circulation cerebral vasculature may be used for management of wide necked aneurysms not amenable to other endovascular approaches. Follow-up angiography sometimes demonstrates neo-intimal hyperplasia within or adjacent to the stent, however there is limited evidence in the literature examining the incidence in MCA and ACA aneurysms. We present our experience with flow diversion of the distal vasculature and evaluate the incidence of neo-intimal hyperplasia. MATERIALS AND METHODS: Retrospective review of patients who underwent Pipeline embolization device (PED) treatment for ruptured and unruptured anterior circulation aneurysms. RESULTS: A total of 251 anterior circulation aneurysms were treated by pipeline flow diversion, of which 175 were ICA aneurysms, 14 were ACA aneurysms and 18 were MCA aneurysms. 6-month follow-up angiography was available in 207 patients. The incidence of neo-intimal hyperplasia was 15.9%, 21.4%, and 61.1% in ICA, ACA, and MCA aneurysms, respectively. MCA-territory aneurysms developed neo-intimal hyperplasia at a significantly higher rate than aneurysms in other vessel territories. Rates of aneurysmal occlusion did not significantly differ from those patients who did not exhibit intimal hyperplasia on follow-up angiography. CONCLUSION: In our experience, flow diversion of distal wide-necked MCA and ACA aneurysms is a safe and effective treatment strategy. The presence of neo-intimal hyperplasia at 6-month angiography is typically clinically asymptomatic. Given the statistically higher rate of neo-intimal hyperplasia in MCA aneurysms at 6-month angiography, we propose delaying initial follow-up angiography to 12-months and maintaining dual antiplatelet therapy during that time.

SARS-CoV-2, the virus responsible for novel Coronavirus (COVID-19) infection, has recently been associated with a myriad of hematologic derangements; in particular, an unusually high incidence of venous thromboembolism has been reported in patients with COVID-19 infection. It is postulated that either the cytokine storm induced by the viral infection or endothelial damage caused by viral binding to the ACE-2 receptor may activate a cascade leading to a hypercoaguable state. Although pulmonary embolism and deep venous thrombosis have been well described in patients with COVID-19 infection, there is a paucity of literature on cerebral venous sinus thrombosis (cVST) associated with COVID-19 infection. cVST is an uncommon etiology of stroke and has a higher occurrence in women and young people. We report a series of three patients at our institution with confirmed COVID-19 infection and venous sinus thrombosis, two of whom were male and one female. These cases fall outside the typical demographic of patients with cVST, potentially attributable to COVID-19 induced hypercoaguability. This illustrates the importance of maintaining a high index of suspicion for cVST in patients with COVID-19 infection, particularly those with unexplained cerebral hemorrhage, or infarcts with an atypical pattern for arterial occlusive disease.

SARS-CoV-2 infection has been associated with ischemic stroke as well as systemic complications such as acute respiratory failure; cytotoxic edema is a well-known sequelae of acute ischemic stroke and can be worsened by the presence of hypercarbia induced by respiratory failure. We present the case of a very rapid neurologic and radiographic decline of a patient with an acute ischemic stroke who developed rapid fulminant cerebral edema leading to herniation in the setting of hypercarbic respiratory failure attributed to SARS-CoV-2 infection. Given the elevated incidence of cerebrovascular complications in patients with COVID-19, it is imperative for clinicians to be aware of the risk of rapidly progressive cerebral edema in patients who develop COVID-19 associated acute respiratory distress syndrome.

The current COVID-19 pandemic has recently brought to attention the myriad of neuro- logic sequelae associated with Coronavirus infection including the predilection for stroke, particularly in young patients. Reversible cerebral vasoconstriction syndrome (RCVS) is a well-described clinical syndrome leading to vasoconstriction in the intracra- nial vessels, and has been associated with convexity subarachnoid hemorrhage and oc- casionally cervical artery dissection. It is usually reported in the context of a trigger such as medications, recreational drugs, or the postpartum state; however, it has not been described in COVID-19 infection. We report a case of both cervical vertebral ar- tery dissection as well as convexity subarachnoid hemorrhage due to RCVS, in a pa- tient with COVID-19 infection and no other triggers.

PURPOSE: Optimal management of extracranial carotid artery dissections (eCAD) in pediatric patients is not well documented, and endovascular interventions are rarely reported. METHODS: A 10-year-old girl sustained multiple systemic injuries in a motor vehicle accident, including an eCAD with pseudoaneurysm. She initially failed both aspirin and endovascular stenting with progressive enlargement of a traumatic cervical carotid pseudoaneurysm and stenosis. RESULTS: Second-stage endovascular stent placement with coiling resulted in successful occlusion of the pseudoaneurysm. At 30-month imaging follow-up, the parent vessel remained patent with no evidence of the pseudoaneurysm. CONCLUSION: In the setting of poly-trauma, management of eCAD can be complex especially in the pediatric population. There is little data on the endovascular treatment of eCAD in children. Failed endovascular therapies are extremely rare. Our report supports surveillance imaging as repeat endovascular treatment may be necessary.

Sinus pericranii (SP) are abnormal vascular connections between extracranial scalp venous channels and intracranial dural sinuses. This vascular abnormality rarely results in significant sequelae, but in select cases, it can be symptomatic. We describe the case of a 7-year-old girl with an SP who experienced intermittent visual, motor, and sensory symptoms not previously described in the literature. Her symptoms resolved after surgical treatment of the SP. We propose a mechanism for her symptoms and the rationale for the role of neurosurgical intervention along with a review of the literature.

INTRODUCTION: Acute kidney injury (AKI) is associated with poor outcome in aneurysmal subarachnoid hemorrhage patients (aSAH). Frailty has recently been demonstrated to correlate with elevated mortality and morbidity; its impact on predicting AKI and mortality in aSAH patients has not been investigated. OBJECTIVE: Evaluating risk factors and predictors for AKI in aSAH patients. METHODS: aSAH patients from a single-center's prospectively maintained database were retrospectively evaluated for development of AKI within 14 days of admission. Baseline demographic and clinical characteristics were collected. The effect of frailty and other risk factors were evaluated. RESULTS: Of 213 aSAH patients, 53 (33.1%) were frail and 12 (5.6%) developed AKI. Admission serum creatinine (sCr) and peak sCr within 48â h were higher in frail patients. AKI patients showed a trend towards higher frailty. Mortality was significantly higher in AKI than non-AKI aSAH patients. Frailty was a poor predictor of AKI when controlling for Hunt and Hess (HH) grade or age. HH grade ≥ 4 strongly predicted AKI when controlling for frailty. CONCLUSION: AKI in aSAH patients carries a poor prognosis. The HH grade appears to have superior utility as a predictor of AKI in aSAH patients than mFI.

Congenital variants of the aortic arch are important to recognize not only for their association with congenital heart disease, vascular rings, and chromosomal abnormalities but also for the purposes of neurointerventional angiography. While many different variants have been reported in the literature, we present two rare cases of an aortic arch variant that, to the best of our knowledge, has not yet been described in the literature- an anteriorly-directed, independent common origin of both carotid arteries from the ascending aorta, with separate subclavian artery trunks originating from the arch.

Delayed cerebral ischemia (DCI) secondary to vasospasm is a determinate of outcomes following non-traumatic subarachnoid hemorrhage (SAH). SAH patients are monitored using transcranial doppler (TCD) to measure cerebral blood flow velocities (CBFv). However, the accuracy and precision of manually acquired TCD can be operator dependent. The NovaGuide robotic TCD system attempts to standardize acquisition. This investigation evaluated the safety and efficacy of the NovaGuide system in SAH patients in a Neuro ICU. We retrospectively identified 48 NovaGuide scans conducted on SAH patients. Mean and maximum middle cerebral artery (MCA) CBFv were obtained from the NovaGuide and the level of agreement between CBFv and computed tomography angiography (CTA) for vasospasm was determined. Safety of NovaGuide acquisition of CBFv was evaluated based on number of complications with central venous lines (CVL) and external ventricular drains (EVD). There was significant agreement between the NovaGuide and CTA (Cohen's Kappa = 0.74) when maximum MCA CBFv ≥ 120 cm/s was the threshold for vasospasm. 27/48 scans were carried out with CVLs and EVDs present without negative outcomes. The lack of adverse events associated with EVDs/CVLs and the strong congruence between maximal MCA CBFv and CTA illustrates the diagnostic utility of the NovaGuide.

PURPOSE: Aneurysmal recurrence represents a significant drawback of endovascular coiling, particularly in aneurysms that have previously ruptured. Given the high recurrence rate of coiled aneurysms and particularly the risk of posttreatment rupture in previously ruptured aneurysms that have been treated by coiling, the question of how best to treat ruptured aneurysms that recur postcoiling remains. MATERIALS AND METHODS: We conducted a retrospective analysis of twenty patients who underwent pipeline embolization of previously ruptured, coiled cerebral aneurysms. RESULTS: Pipeline embolization device (PED) treatment resulted in complete aneurysmal occlusion in 10 patients (62.5%) at first angiographic follow-up, and 11 patients (68.75%) at last follow-up. No PED-related complications were encountered and there were no peri-procedural or postprocedural hemorrhages, or symptomatic ischemic events following flow diversion. CONCLUSIONS: PED as a second-line treatment is a safe and effective modality for achieving aneurysmal occlusion in recurrent, previously ruptured, primarily coiled aneurysms. Additionally, a staged coil-to-PED approach may be considered for the management of acutely ruptured aneurysms to achieve aneurysmal obliteration in an effort to mitigate recurrence, and reduce the amount of postprocedural studies.
RESUMO
INTRODUCTION: Anterior cerebral artery (ACA) aneurysms are commonly encountered in clinical practice but can be challenging to treat. Flow diversion is a viable treatment in this population. METHODS: We retrospectively evaluated patients treated at our center from May 2017 to December 2020 who underwent flow diversion for an ACA aneurysm at or distal to the anterior communicating artery (ACOM). We defined ACA aneurysms as any aneurysm involving the ACOM itself, at the junction of the ACA with the ACOM (A1/A2), or in distal A2/A3 branches; both ruptured and unruptured aneurysms were included. Baseline and follow-up clinical and angiographic data were collected; the primary measure was elimination of the aneurysm on follow-up angiogram. Patients underwent flow diversion with a Pipeline stent. A single flow diverting stent was placed in the dominant ACA spanning from the A2 segment extending into the A1 segment; two patients required H-pipe technique. Distal aneurysms were treated with a single Pipeline device deployed across the parent vessel, covering the aneurysm. RESULTS: Two-seven patients underwent a total of 28 flow diversion procedures; median age was 57 and 16 (59.3%) were male. Thirteen (48.2%) patients presented with subarachnoid hemorrhage; of these, four were treated within 6 weeks of the index hemorrhage. Most patients (22; 81.5%) had significant ACA asymmetry. There was one postoperative intracerebral hemorrhage and one groin complication. Follow-up data were available for 19 patients, 15 (78.9%) of which showed no residual aneurysm and 17 (89.5%) had protection of the dome. CONCLUSION: Flow diversion of ACA aneurysms can be a primary treatment modality in an unruptured aneurysm or a complement to initial coil protection of a ruptured aneurysm. Further studies are needed to confirm these results.
RESUMO
BACKGROUND: Arachnoid cysts (AC) may cause hydrocephalus and neurological symptoms, necessitating surgical intervention. Cyst drainage may result in postoperative complications, however, these interventions are not normally associated with the subsequent development of acute hydrocephalus. Herein, we present two unique cases of AC drainage with postoperative development of acute communicating hydrocephalus. CASE DESCRIPTION: Case 1. A 75-year-old female presented with progressive headaches, cognitive decline, and questionable seizures. Her neurological examination was non-focal, but a head computed tomography scan (CT) identified a large right frontal AC with mass effect. She subsequently underwent craniotomy and decompression of the cyst. Postoperatively, her neurological examination deteriorated, and a head CT demonstrated new communicating hydrocephalus. The opening pressure was elevated upon placement of an external ventricular drain. Her hydrocephalus improved on follow-up imaging, but her neurological examination failed to improve, and she ultimately expired. Case 2. A 61-year-old female presented with headache and seizures attributed to a left parietal AC. She underwent open craniotomy for fenestration of the cyst into the Sylvian fissure. Postoperatively, her neurologic examination deteriorated, and she developed acute communicating hydrocephalus. She was initially managed with external ventricular drainage (EVD). The hydrocephalus resolved after several days, and the EVD was subsequently removed. Late follow-up imaging at 2 years showed that the regression of the AC was maintained. CONCLUSION: Acute development of hydrocephalus is a potential complication of intracranial AC fenestration. A better understanding of intracranial cerebrospinal fluid flow dynamics may better inform as to the underlying cause of this complication.
RESUMO
BACKGROUND: Aneurysmal ruptures typically cause subarachnoid bleeding with intraparenchymal and intraventricular extension. However, rare instances of acute aneurysmal ruptures present with concomitant, non-traumatic subdural hemorrhage (SDH). We explored the incidence and difference in outcomes of SDH with aneurysmal subarachnoid hemorrhage (aSAH) as compared with aSAH alone. METHODS: Retrospective cohort study from 2012 to 2015 from the National (Nationwide) Inpatient Sample (NIS) (20% stratified sample of all hospitals in the United States). NIS database (2012 to September 2015) queried to identify all patients presenting with aSAH. From this population, the patients with concomitant SDH were identified. RESULTS: A total of 10 075 patients with both cerebral aneurysms and aSAH were included. Of these, 335 cases of concomitant SDH and aSAH were identified. There was no significant change in the rate of SDH in aSAH over time. SDH with aSAH patients had a mortality of 24% compared with 12% (p=0.003) in the SAH only group, and only 16% were discharged home vs 37% (p=0.003) in the SAH group. CONCLUSIONS: There is a 3.5% incidence of acute SDH in patients presenting with non-traumatic aSAH. Patients with SDH and aSAH have nearly double the mortality, higher rate of discharge to nursing home and rehabilitation, and a significantly lower rate of discharge to home and return to routine functioning. This information is useful in counseling and prognostication of patients with concomitant SDH and aSAH.

Cerebral arteriovenous malformations (AVMs) are a complex and heterogeneous pathology which require an understanding of the natural history of these lesions, as well as the potential treatment options in order to manage them safely. While treatment is the agreed upon strategy for most ruptured AVMs, the management of unruptured AVMs continues to be debated. More recently, this debate has been fueled by the A Randomized Trial of Unruptured Arteriovenous Malformations (ARUBA) trial which attempts to define the natural history and treatment risk of AVMs. However, the trial has significant shortcomings which limit its broad applicability. In addition, the breadth, efficacy, and safety of potential treatment options continue to improve. This review focuses on defining the natural history of cerebral AVMs, an overview of the ARUBA trial, and the most current treatment paradigm for cerebral AVMs.

Although hyperglycemia is associated with worse outcomes after aneurysmal subarachnoid hemorrhage (aSAH), there is no consensus on the optimal glucose control metric, acceptable in-hospital glucose ranges, or suitable insulin regimens in this population. In this single-center retrospective cohort study of aSAH patients, admission glucose, and hospital glucose mean (MHG), minimum (MinG), maximum (MaxG), and variability were compared. Primary endpoints (mortality, complications, and vasospasm) were assessed using multivariate logistic regressions. Of the 217 patients included, complications occurred in 83 (38.2%), 124 (57.1%) had vasospasm, and 41 (18.9%) died. MHG was independently associated with (p < 0.001) mortality, MaxG (p = 0.017) with complications, and lower MinG (p = 0.015) with vasospasm. Patients with MHG ≥ 140 mg/dL had 10 × increased odds of death [odds ratio (OR) = 10.3; 95% CI 4.6-21.5; p < 0.0001] while those with MinG ≤ 90 mg/dL had nearly 2× increased odds of vasospasm (OR = 1.8; 95% CI 1.01-3.21; p = 0.0422). While inpatient insulin was associated with increased complications and provided no mortality benefit, among those with MHG ≥ 140 mg/dL insulin therapy resulted in lower mortality (OR = 0.3; 95% CI 0.1-0.9; p = 0.0358), but no increased complication risk. While elevated MHG and MaxG are highly associated with poorer outcomes after aSAH, lower MinG is associated with increased vasospasm risk. Future trials should consider initiating insulin therapy based on MHG rather than other hyperglycemia measures.

OBJECTIVE: Spinal epidural abscess (SEA) patients have increased medical comorbidities and risk factors for infection compared with those without SEA. However, the association between frailty and SEA patients has not been documented. METHODS: A total of 46 SEA patients were randomly paired and matched by age and sex with a control group of patients with back pain who had presented to our emergency department from 2012 to 2017. Statistical analysis identified the risk factors associated with SEA and frailty using the modified frailty index (mFI), and the patients were stratified into robust, prefrail, and frail groups. We examined the value of the mFI as a prognostic predictor and evaluated the classic risk factors (CRFs). RESULTS: The SEA patients had higher mFIs and CRFs (P = 0.023 and P < 0.001, respectively) and a longer length of stay (22.89 days vs. 1.72 days; P < 0.001). Of the mFI variables, only diabetes had a significant association with SEA (odds ratio [OR], 3.60; P = 0.012). Among the stratified mFI subgroups, a frail ranking (mFI >2) was the strongest risk factor for SEA (OR, 5.18; P = 0.003). A robust ranking (mFI, 0-1) was a weak negative predictor for SEA (OR, 0.41; P = 0.058). The robust patients were also more likely to be discharged to home (OR, 7.58; P = 0.002). Of the CRF variables, only intravenous drug use had a statistically significant association with SEA (OR, 10.72; P = 0.015). CONCLUSIONS: Patients with SEA were more frail compared with the control back pain patients. Frailty was determined to be an independent risk factor for SEA, outside of the CRFs. The use of the mFI could be potentially useful in predicting the diagnosis, prognosticating, and guiding SEA treatment.
