RESUMO
BACKGROUND: Infectious intracranial aneurysms (IIAs) are a rare sequel of systemic infection and occur most commonly in patients with infective endocarditis (IE). Despite the increasing use of non-invasive screening angiography in patients with IE, the incidence remains low, yielding limited data on the management of IIAs in pediatric populations. We performed a pooled analysis of all published series of pediatric patients with IIAs to study the disease landscape including presentation, management, and outcomes. METHODS: Data included in this study were pooled from published literature on IIAs between 1960 and 2023. Abstracts were selected for full review to include only manuscripts reporting at least one case of pediatric IIA (age 0-18 years). RESULTS: A total of 145 pediatric patients with 178 IIAs were included. Patients presented with rupture in 68% of cases, of which 36% had intraparenchymal hemorrhage and 39% had subarachnoid hemorrhage. Using multivariate logistic regression, independent predictors of rupture were posterior location (aOR 10, P=0.041) and history of IE (aOR 7.2, P=0.001). Primary medical management was successful in 82% of cases with unruptured aneurysms while, in those with ruptured IIAs, medical management was successful in 26% of cases. The 90-day mortality rate was 28%. Using multivariate logistic regression, ruptured IIAs (aOR 5.4, P<0.01) and failure of medical management (aOR 11.1, P<0.05) were independent predictors of 90-day mortality. CONCLUSION: Pediatric IIAs remain a rare complication of systemic or localized CNS infection in the pediatric population. Medical management of unruptured aneurysms is highly successful, while ruptured aneurysms have a remarkably high rate of failure of medical management and should be treated by early surgical or endovascular intervention when feasible.
RESUMO
Multiple alternative sites for distal ventriculoperitoneal shunts have been described including pleural, atrial, ureteral, fallopian, and gallbladder placement. In medically complex patients the sites for cerebrospinal fluid (CSF) diversion can be exhausted. We present a case where open retroperitoneal inferior vena cava cannulation was used for successful atrial catheter placement in a 17-month-old female. The patient had a complex abdominal, pulmonary, and vascular history precluding placement of the distal catheter in other sites or atrial placement through more peripheral venous cannulation. The patient underwent uncomplicated open retroperitoneal exposure of her inferior vena cava (IVC) with cannulation and placement of atrial catheter under fluoroscopic guidance. At the follow-up one year after surgery, the patient did not require revision with appropriate placement of the distal atrial catheter.
RESUMO
OBJECTIVE: The management of hydrocephalus resulting from intraventricular hemorrhage related to extreme prematurity remains demanding. Given the complexities of controlling hydrocephalus in this population, less commonly used procedures may be required. The authors examined the utility of ventriculogallbladder (VGB) shunts in a series of such children. METHODS: The authors retrospectively reviewed the medical records of all children who underwent surgery for hydrocephalus in the period from 2011 through 2019 at Children's Healthcare of Atlanta. Six patients who underwent VGB shunt placement were identified among a larger cohort of 609 patients who had either a new shunt or a newly changed distal terminus site. The authors present an analysis of this series, including a case of laparoscopy-assisted distal VGB shunt revision. RESULTS: The mean age at initial shunt placement was 5.1 months (range 3.0-9.4 months), with patients undergoing a mean of 11.8 shunt procedures (range 5-17) prior to the initial VGB shunt placement at a mean age of 5.3 years (range 7.9 months-12.8 years). All 6 patients with VGB shunt placement had hydrocephalus related to extreme prematurity (gestational age < 28 weeks). At the time of VGB shunt placement, all had complex medical and surgical histories, including poor venous access due to congenital or iatrogenic thrombosis or thrombophlebitis and a peritoneum hostile to distal shunt placement related to severe necrotizing enterocolitis. VGB complications included 1 case of shunt infection, identified at postoperative day 6, and 2 cases of distal shunt failure due to retraction of the distal end of the VGB shunt. In all, there were 3 conversions back to ventriculoperitoneal or ventriculoatrial shunts due to the 2 previously mentioned complications, plus 1 patient who outgrew their initial VGB shunt. Three of 6 patients remain with a VGB shunt, including 1 who underwent laparoscopy-assisted distal shunt revision 110.5 months after initial VGB shunt insertion. CONCLUSIONS: Placement of VGB shunts should be considered in the armamentarium of procedures that may be used in the particularly difficult cohort of children with hydrocephalus related to extreme prematurity. VGB shunts show utility as both a definitive treatment and as a "bridge" procedure until the patient is larger and comorbid abdominal and/or vascular issues have resolved sufficiently to allow conversion back to ventriculoperitoneal or ventriculoatrial shunts, if needed.

BACKGROUND: It is expected that the incidence of cerebrospinal fluid (CSF) shunt malfunctions would remain unchanged during the shelter-in-place period related to the COVID-19 pandemic. OBJECTIVE: To examine the number of shunt surgeries performed in a single institution during this time interval in comparison to equivalent periods in past years. METHODS: The numbers of elective and emergent/urgent shunt surgeries performed at a single institution were queried for a 28-d period starting on the third Monday of March, between years 2015 and 2020. These were further stratified by how they presented as well as the type of surgery performed. RESULTS: During the 28-d period of interest, in the years between 2015 and 2020, there was a steady increase in the number of shunt surgeries performed, with a maximum of 64 shunt surgeries performed in 2019. Of these, approximately 50% presented in urgent fashion in any given year. In the 4-wk period starting March 16, 2020, a total of 32 shunt surgeries were performed, with 15 of those cases presenting from the outpatient setting in emergent/urgent fashion. For the surgeries performed, there was a statistically significant decrease in the number of revision shunt surgeries performed. CONCLUSION: During the 2020 COVID-19 pandemic, there was an unexpected decrease in the number of shunt surgeries performed, and particularly in the number of revision surgeries performed. This suggests that an environmental factor related to the pandemic is altering the presentation rate of shunt malfunctions.

OBJECTIVE Past studies have suggested correlations between abusive head trauma and concurrent cervical spine (c-spine) injury. Accordingly, c-spine MRI (cMRI) has been increasingly used in radiographic assessments. This study aimed to determine trends in cMRI use and treatment, and outcomes related to c-spine injury in children with nonaccidental trauma (NAT). METHODS A total of 503 patients with NAT who were treated between 2009 and 2014 at a single pediatric health care system were identified from a prospectively maintained database. Additional data on selected clinical events were retrospectively collected from electronic medical records. In 2012, a clinical pathway on cMRI usage for patients with NAT was implemented. The present study compared cMRI use and clinical outcomes between the prepathway (2009-2011) and postpathway (2012-2014) periods. RESULTS There were 249 patients in the prepathway and 254 in the postpathway groups. Incidences of cranial injury and Injury Severity Scores were not significantly different between the 2 groups. More patients underwent cMRI in the years after clinical pathway implementation than before (2.8% vs 33.1%, p < 0.0001). There was also a significant increase in cervical collar usage from 16.5% to 27.6% (p = 0.004), and more patients were discharged home with cervical collar immobilization. Surgical stabilization occurred in a single case in the postpathway group. CONCLUSIONS Heightened awareness of potential c-spine injury in this population increased the use of cMRI and cervical collar immobilization over a 6-year period. However, severe c-spine injury remains rare, and increased use of cMRI might not affect outcomes markedly.

OBJECTIVE Various indicators are used to evaluate the quality of care delivered by surgical services, one of which is early reoperation rate. The indications and rate of reoperations within a 48-hour time period have not been previously reported for pediatric neurosurgery. METHODS Between May 1, 2009, and December 30, 2014, 7942 surgeries were performed by the pediatric neurosurgery service in the operating rooms at a single institution. Demographic, socioeconomic, and clinical characteristics associated with each of the operations were prospectively collected. The procedures were grouped into 31 categories based on the nature of the procedure and underlying diseases. Reoperations within 48 hours at the conclusion of the index surgery were reviewed to determine whether the reoperation was planned or unplanned. Multivariate logistic regression was employed to analyze risk factors associated with unplanned reoperations. RESULTS Cerebrospinal fluid shunt-and hydrocephalus-related surgeries accounted for 3245 (40.8%) of the 7942 procedures. Spinal procedures, craniotomy for tumor resections, craniotomy for traumatic injury, and craniofacial reconstructions accounted for an additional 8.7%, 6.8%, 4.5%, and 4.5% of surgical volume. There were 221 reoperations within 48 hours of the index surgery, yielding an overall incidence of 2.78%; 159 of the reoperation were unplanned. Of these 159 unplanned reoperations, 121 followed index operations involving shunt manipulations. Using unplanned reoperations as the dependent variable (n = 159), index operations with a starting time after 3 pm and admission through the emergency department (ED) were associated with a two- to threefold increase in the likelihood of reoperations (after-hour surgery, odds ratio [OR] 2.01 [95% CI 1.43-2.83, p < 0.001]; ED admission, OR 1.97 (95% CI 1.32-2.96, p < 0.05]). CONCLUSIONS Approximately 25% of the reoperations within 48 hours of a pediatric neurosurgical procedure were planned. When reoperations were unplanned, contributing factors could be both surgeon related and system related. Further study is required to determine the extent to which these reoperations are preventable. The utility of unplanned reoperation as a quality indicator is dependent on proper definition, analysis, and calculation.
