Huge hydrocephalus: a rare case series with insights into management and outcomes of this neglected cohort.

PURPOSE: This study aims to discuss the management challenges of huge hydrocephalus (HH), a severe subset of hydrocephalus, presenting predominantly in underprivileged backgrounds. Insights into the condition's characteristics, factors affecting outcomes, and associated morbidity are discussed. METHODS: A retrospective review of all operated cases of hydrocephalus with head circumference greater than body length (HC>L) was conducted (January 2019-January 2023). Data on epidemiological parameters, associated cranial abnormalities, cortical mantle thickness, peri-conceptional folic acid intake, surgical interventions, age-appropriate milestones, and complications were collected. Follow-up was conducted for at least 12 months or until expiration. RESULTS: The cohort consisted of 7 males and 5 females with age ranging from 3 to 48 months. 33% of them had associated neurological abnormalities, and 18 surgical interventions were needed for these 12 cases, including ventriculoperitoneal shunt or endoscopic diversion. A 17% wound breakdown rate requiring re-suturing was present, and 33% of cases had postoperative CSF infection, with 33% mortality, with only one case having age-appropriate development seen. The average hospital stay was 11.9 days, six times our center's average. All cases with an Evans index with an average of 0.7 expired within 12 months. None of the 12 mothers took peri-conceptional folic acid, and no case agreed to reduction cranioplasty. CONCLUSION: Huge hydrocephalus is a rare cohort with significant management challenges and poor prognosis even after treatment. Factors such as delayed intervention and low socioeconomic status contribute to adverse outcomes. Prevention through peri-conceptual folic acid intake and addressing socioeconomic disparities is crucial in reducing disease burden and improving prognosis.

Decompressive craniectomy in children: indications and outcome from a tertiary centre.

INTRODUCTION: The role of decompressive craniectomy (DC) is as a rescue therapy for the treatment of intracranial hypertension. The indications for the DC are variable. METHODS: The clinical details, imaging, operative findings and follow-up data of children less than or equal to 18 years of age were reviewed for more information on the children who underwent DC in the last 5 years. RESULTS: During the study period, a total of 128 children underwent DC. The trauma cases were 66, and the non-trauma cases were 62. The common indication for DC was pure acute subdural hematoma 33 (50%), followed by contusion 10 (15%) in the trauma group, and in non-trauma, arterial infarction in 20 (32%) and cerebral venous thrombosis in 17 (27%). Hemicraniectomy was done in 114 (89%), and bifrontal craniectomy was done in 7 (5.4%) cases. The median duration follow-up was 7 months in non-trauma and 6 months in trauma. GCS was less than 8, the motor score was less than 3, and pupillary asymmetry, hypotension and basal cistern effacement were factors related to an unfavourable outcome in the non-trauma group. In regression analysis, only a motor score of less than three was associated with the non-trauma group. Age less than 10 years, GCS less than 8, motor score less than three and preoperative infarction were the predictive factors in univariate analysis, and only GCS less than 8 was the predictive factor for unfavourable factors in regression analysis in the trauma group. CONCLUSION: The DC is performed as a lifesaving procedure. The unfavourable outcome is slightly higher in non-trauma cases compared to trauma cases. However, the mortality rate is high in trauma cases.

An Illustrative Review of the Pathomechanisms of Symptomatic Developmental Venous Anomalies.

OBJECTIVE: Symptomatic developmental venous anomalies (DVAs) are rare. Here, we illustrate the varied clinicoradiologic profiles of symptomatic DVAs and contemplate the mechanisms that render these (allegedly) benign entities symptomatic supported by a review of literature. METHODS: Institutional databases were searched to identify cases of symptomatic DVAs. Clinical and imaging (angiographic and cross-sectional) data of 9 cases with 11 neurovascular symptoms consequent to inflow/outflow perturbations and mechanical obstruction that manifested because of the strategic topography of underlying DVAs were analyzed. A review of the existing literature on DVAs in agreement with our case series was performed on publications retrieved from the PubMed database. RESULTS: Symptoms secondary to venous hypertension arising from flow-related perturbations were broadly divided into those arising from restricted outflow and increased inflow. Restricted outflow occurred because of collector vein stenosis (n = 2) and collector vein/DVA thrombosis (n = 3), whereas the latter pathomechanism was initiated by arterialized/transitional DVAs (n = 2). A mechanical/obstructive pathomechanism culminating in moderate supratentorial ventriculomegaly was noted in 1 case. One patient was given a diagnosis of hemorrhage associated with a cavernoma. CONCLUSIONS: Awareness and contextualization of potential flow-related perturbations and mechanical insults that render DVAs symptomatic aid in accurate diagnosis, management, and prognostication.

Torsion of giant occipital encephalocoele in a 2-day-old infant: emergent surgery and outcome.

INTRODUCTION: Torsion of a giant occipital encephalocele leading to necrosis is an extremely rare complication found in neonates with only two such cases reported in literature previously. Infection and ulceration of the necrosed skin may lead to meningitis or sepsis. We present here a neonate with giant occipital encephalocele showing progressive necrosis during the first day of his life. CASE REPORT: A new-born baby, delivered vaginally, with no antenatal imaging was found to have a huge mass in the occipital region, which was covered by normal pink-purplish skin. During the first day of his life, the sac started becoming ulcerated accompanied with a rapid colour change in the skin, gradually turning darker and then black. The pedicle of the encephalocele was twisted with progressive necrosis of the encephalocele. MRI showed a giant encephalocele with single vein draining into the torcula and dysplastic occipital lobe herniating into the defect. The neonate was taken up for urgent excision and repair of the encephalocele. The encephalocele was excised 'in-total' with 'figure-of-8' repair of the meninges. One year after the operation, she appears to be well-developed without any neurological problems. CONCLUSION: Necrosis may have resulted from arterial or venous compromise caused by torsion of the pedicle during delivery or after birth. The high pressure inside the sac associated with the thin skin of the encephalocele may be another predisposing factor. In view of the risk of meningitis and rupture, immediate surgery with repair with minimal blood loss is indicated.

Paediatric chronic subdural haematoma: what are the predisposing factors and outcomes in management of these cases?

INTRODUCTION: Chronic subdural hematoma (cSDH) is a disease of the elderly population. Incidence in paediatric population is relatively uncommon. Child abuse, birth trauma, coagulopathy and shunt surgeries represent major causes. Major impact of the disease on life of patient due to recurrence and repeat surgical procedure is significant, not to mention the burden on health care system. MATERIAL AND METHODS: We retrospectively reviewed our institute data for chronic sub-dural cases for the past 10 years (2008-2018) and collected data on the demography, clinical features, metabolic workup, mode of treatment, recurrence rates, predisposing factors, laterality, hematoma characteristics and factors associated with recurrence in all cases with less than or equal to 18 years of age. RESULTS: A total of 30 such cases were found in a period of 10 years (2008-2018). The mean patient age was 7.3 years (range 2 months-17 years), with 20 males (66.67%) and 10 females (33.33%). Raised intracranial pressure (n = 9) was the commonest presenting symptom in 30% of cases followed by seizures in 26.67% (n = 8). The previous shunt was the commonest predisposing factor seen in 43.33% (n = 13). cSDHs were unilateral in 56.67% cases (n = 17) and bilateral in 43.33% (n = 13). Burr hole craniostomy was done in 27 cases (90%), and conservative management was done in three cases (10%). Follow up was available for 27 cases (90%) with a mean follow up duration of 24 months. Recurrence rate was 30% (n = 9). Shunt surgery contributed to 77% of bilateral disease (p = 0.009). Child abuse was not reported in our series. CONCLUSION: Presence of paediatric cSDH is alarming, and the physician should be alerted to look for underlying cause and rule out child abuse. Detailed metabolic, skeletal workup is required. Treatment of primary pathology should be the goal as CSF diversion is not the solution to all problems, but can definitely be the cause of all the problems.

The role of radiation therapy in the treatment of spine metastases from hepatocellular carcinoma: a systematic review and meta-analysis.

OBJECTIVE: Spine hepatocellular carcinoma (HCC) metastases severely worsen quality of life and prognosis, with the role of radiotherapy being controversial. The authors systematically reviewed the literature on radiotherapy for spine metastatic HCCs. METHODS: The PubMed, Scopus, Web of Science, and Cochrane databases were searched according to the PRISMA guidelines to include studies of radiotherapy for spine metastatic HCCs. Outcomes, complications, and local control were analyzed with indirect random-effect meta-analyses. RESULTS: The authors included 12 studies comprising 713 patients. The median time interval from diagnosis of HCC to spine metastases was 12 months (range 0-105 months). Most lesions were thoracic (35.9%) or lumbar (24.7%). Radiotherapy was delivered with conventional external-beam (67.3%) or stereotactic (31.7%) techniques. The median dose was 30.3 Gy (range 12.5-52 Gy) in a median of 5 fractions (range 1-20 fractions). The median biologically effective dose was 44.8 Gy10 (range 14.4-112.5 Gy10). Actuarial rates of postradiotherapy pain relief and radiological response were 87% (95% CI 84%-90%) and 70% (95% CI 65%-75%), respectively. Radiation-related adverse events and vertebral fractures had actuarial rates of 8% (95% CI 5%-11%) and 16% (95% CI 10%-23%), respectively, with fracture rates significantly higher after stereotactic radiotherapy (p = 0.033). Fifty-eight patients (27.6%) had local recurrences after a median of 6.8 months (range 0.1-59 months), with pooled local control rates of 61.6% at 6 months and 40.8% at 12 months, and there were no significant differences based on radiotherapy type (p = 0.068). The median survival was 6 months (range 0.1-62 months), with pooled rates of 52.5% at 6 months and 23.4% at 12 months. CONCLUSIONS: Radiotherapy in spine metastatic HCCs shows favorable rates of pain relief, radiological responses, and local control. Rates of postradiotherapy vertebral fractures are higher after high-dose stereotactic radiotherapy.

Largest neurosurgical social media group and its impact on communication and research.

BACKGROUND: The use of social media to communicate and disseminate knowledge has increased exponentially, especially in the field of neurosurgery. 'Neurosurgery cocktail' (NC) was developed by a group of young neurosurgeons as a means of sharing didactic materials and clinical experiences via social media. It connects 35.000 neurosurgeons worldwide on multiple platforms, primarily Facebook and Twitter. Given the rising utilization of social media in neurosurgery, the popularity of NC has also increased since its inception. In this study, the authors surveyed the social media analytics of NC for both Facebook and Twitter. Besides, we reviewed the literature on the use of social media in neurosurgery. METHODS: Facebook and Twitter metrics were extracted through each respective platform's analytics tools from December 2020 (earliest available date for data analysis) through January 2021. A literature search was conducted using PubMed (MEDLINE) and Scopus databases. RESULTS: On Facebook, as of January 2021, the group had a total of 25.590 members (87.6% male), most commonly (29%) between 35 and 44 years of age with over 100 countries were represented. As of January 2021, they had amassed 6457 followers on Twitter. During the last 28 d between December 2020 and January 2021, the account published 65 tweets that garnered a total of 196,900 impressions. Twelve articles were identified in our literature review on the use of social media within the neurosurgical community. CONCLUSIONS: NC is one of the most widely utilized neurosurgical social media resources available. Sharing knowledge has been broadened thanks to the recent social media evolution, and NC has become a leading player in disseminating neurosurgical knowledge.

Varied imaging and clinical presentations of acute bacterial cerebritis.

Infectious diseases affecting the central nervous system remain an important cause of morbidity and mortality in developing countries and in immunocompromised patients. Cerebritis refers to pyogenic inflammation of the brain parenchyma that may lead to abscess formation if left untreated. Cerebritis is an uncommon diagnosis as patients are usually diagnosed at the stage of abscess formation. We present three cases of bacterial cerebritis with different clinical manifestations and varied appearances on MRI. To our knowledge, only few case reports of bacterial cerebritis have been published in the literature, and imaging findings are not fully elucidated. These cases of bacterial cerebritis add valuable information to the existing literature and would be helpful in making the appropriate diagnosis of this uncommon condition that can be medically managed if diagnosed appropriately. We recommend that cerebritis should be considered in the differential diagnosis of such lesions.

Intracranial kaposiform hemangioendothelioma presenting as epistaxis: a rare case report with review of literature.

INTRODUCTION: Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor of intermediate malignancy with tendency for local invasion and recurrence. The tumor almost exclusively occurs in children, especially in infants. Intracranial KHE are extremely rare with only two cases reported in the literature. REPORT: We report the clinical and pathological features of this rare tumor arising from basitemporal region in a 21-month child. Our case did not present with Kasabach-Merritt phenomenon. Histopathological examination confirmed the diagnosis of KHE. CONCLUSION: KHE should be considered in the differential diagnosis of intracranial extra-axial neoplasm in children, and histopathological examination plays an important role in distinguishing KHE from its morphologic mimics. It is essential to diagnose KHE due to its locally aggressive nature.

Intracranial hypertension in patients with aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis.

Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating and life-threatening condition with high mortality and morbidity. Even though there is an association with intracranial pressure (ICP) raise and aSAH, there is a lack of recommendations regarding the indications for ICP monitoring in patients with aSAH. Defining what patients are at a higher risk to develop intracranial hypertension and its role in the functional outcome and mortality in patients with aSAH will be the purpose of the following systematic review and meta-analysis. The primary endpoint is to determine the prevalence and impact on mortality of ICP in patients with aSAH. Secondary endpoints aim to describe the variables related to the development of ICP and the relationship between traumatic and aneurysmal etiology of intracranial hypertension. PubMed, Embase, Central Cochrane Registry of Controlled Trials, and research meeting abstracts were searched up to August 2019 for studies that performed ICP monitoring, assessed the prevalence of intracranial hypertension and the mortality, in adults. Newcastle Ottawa scale (NOS) was used to assess study quality. The statistical analysis was performed using the Mantel-Haenszel methodology for the prevalence and mortality of intracranial hypertension for reasons with a randomized effect analysis model. Heterogeneity was assessed by I2. A total of 110 bibliographic citations were identified, 20 were considered potentially eligible, and after a review of the full text, 12 studies were considered eligible and 5 met the inclusion criteria for this review. One study obtained 7 points in the NOS, another obtained 6 points, and the rest obtained 5 points. Five studies were chosen for the final analysis, involving 793 patients. The rate of intracranial hypertension secondary to aSAH was 70.69% (95% CI 56.79-82.84%) showing high heterogeneity (I2 = 92.48%, p = < 0.0001). The results of the meta-analysis of mortality rate associated with intracranial hypertension after aSAH found a total of four studies, which involved 385 patients. The mortality rate was 30.3% (95% CI: 14.79-48.57%). Heterogeneity was statistically significant (I2 = 90.36%; p value for heterogeneity < 0.001). We found that in several studies, they reported that a high degree of clinical severity scale (Hunt and Hess or WNFS) and tomographic (Fisher) were significantly correlated with the increase in ICP above 20 mmHg (P < 0.05). The interpretation of the results could be underestimated for the design heterogeneity of the included studies. New protocols establishing the indications for ICP monitoring in aSAH are needed. Given the high heterogeneity of the studies included, we cannot provide clinical recommendations regarding this issue.

Avoiding predatory publishing for early career neurosurgeons: what should you know before you submit?

BACKGROUND: Scientific research can offer the joy of discovery. For many graduating neurosurgeons, often, a seminar, class, or instructional module is their first and only formal exposure to the world of conducting research responsibly, to write down and report the results of such research. The pressure to publish scientific research is high, but any young neurosurgeon who is unaware of how predatory publishers operate can get duped by it and can lose their valuable and hard-fought research. Hence, we have attempted to provide an overview of all potentially predatory neurosurgery publications and provide some "red flags" to recognize them. METHODS: A suspected list of predatory publications was collected via a thorough review of the Neurosurgery journals listed in 4 major so-called blacklists, i.e., Beall's list, Manca's list, Cabell's blacklist, and Strinzel blacklist and then cross-referenced with UGC CARE whitelist to remove any potential legitimate journals. All journals with a scope of the Neurosurgery publication were searched using terms in the search bar: "Neurosurgery", "Neuroanatomy", "Neuropathology", and "Neurological disorder/disease". Since all predatory journals claim to be open access, all possible types of open access journals on Scimago were also searched, and thus a comparison was possible in terms of publication cost and number of legitimate open access journals when compared with predatory ones. In addition, methodologies by which these journals penetrate legitimate indexes like PubMed was investigated. RESULTS: A total of 46 predatory journals were found and were enlisted along with their publishers and web addresses. Sixty of the 360 Neurosurgery journals listed on Scimago were open access and the fee for the predatory journals was substantially lower (< $150) when compared with legitimate journals ($900-$3000). Six types of open access types exist while a total of 26 red flags in 7 stages of publication can be found in predatory journals. These journals have penetrated indexes by having similar names to legitimate journals and by publishing articles with external funding which mandate their indexing. CONCLUSION: These 46 journals were defined as predatory by 4 major blacklists, and none of them was found in the UGC Care white list. They also fulfill the 26 red-flags that define a predatory journal. The blacklist detailed here may become redundant; hence "whenever in doubt" regarding a journal with "red-flags", the authors are advised to refer to whitelists to be on the safer side. Publishing in predatory journals leads to not only loss of valuable research but also discredits a researcher among his peers and can be hindrance in career progression. Some journals are even indexed on PubMed, and they have sophisticated webpages and high-quality online presentations.

Hemoglobin levels as a transfusion criterion in moderate to severe traumatic brain injury: a systematic review and meta-analysis.

BACKGROUND: Several factors can influence the outcome of severe head injuries including the patient's hemoglobin levels. There has often been a dilemma regarding levels of hemoglobin at which red cell blood transfusion (RCBT) should be performed. OBJECTIVE: To systematically review the literature to determine the usefulness of management protocols that have hemoglobin levels <10 g/dL vs <7 g/dL as an RCBT criterion. METHODS: Following the PRISMA statement, the search was constructed using terms and descriptors of the Medical Subject Heading (MeSH), combined with Boolean operators. Full text of these articles was studied, and outcome measures at 3-6 months were considered for patients who were given a RCBT at <10 g/dL or at 7 g/dL hemoglobin levels. RESULTS: A total of 4 articles were found suitable for inclusion in the meta-analysis. RCBT below 7 g/dL was not associated with an increased risk of mortality as compared to RCBT using the value of less than 10 g/dL. RCBT at lower levels of hemoglobin was also not associated with a poor neurological outcome (GOS 4-5) but rather RCBT at lower levels lead to better outcomes (GOS 1-3) and the association was significant. CONCLUSION: Allogenic RCBT was associated with poorer neurological outcomes, within a wide range of reported differences in the hemoglobin threshold to decide for RCBT in TBI patients. Restrictive RCBT strategy may be useful in moderate to severe TBI cases although the risk of anemia-induced cerebral injury needs further investigation regarding the risks and complications inherent to RCBT.

Residency perception survey among neurosurgery residents in lower-middle-income countries: grassroots evaluation of neurosurgery education.

OBJECTIVE: The evolution of the neurosurgical specialty in lower-middle-income countries is uniformly a narrative of continuous struggle for recognition and resource allocation. Therefore, it is not surprising that neurosurgical education and residency training in these countries is relatively nascent. Dr. Harvey Cushing in 1901 declared that he would specialize in neurosurgery and gave his greatest contribution to the advancement of neurosurgical education by laying the foundations of a structured residency training program. Similar efforts in lower-middle-income countries have been impeded by economic instability and the lack of well-established medical education paradigms. The authors sought to evaluate the residency programs in these nations by conducting a survey among the biggest stakeholders in these educational programs: the neurosurgical residents. METHODS: A questionnaire addressing various aspects of the residency program from a resident's perspective was prepared with Google Forms and circulated among neurosurgery residents through social media and email groups. Where applicable, a 5-point Likert scale was used to grade the responses to the questions. Responses were collected from May to October 2019 and analyzed using descriptive statistics. Complete anonymity of the respondents was ensured to keep the responses unbiased. RESULTS: A total of 195 responses were received, with 189 of them from lower-middle-income countries (LMICs). The majority of these were from India (75%), followed by Brazil and Pakistan. An abiding concern among residents was lack of work hour regulations, inadequate exposure to emerging subspecialties, and the need for better hands-on training (> 60% each). Of the training institutions represented, 89% were offering more than 500 major neurosurgical surgeries per year, and 40% of the respondents never got exposure to any subspecialty. The popularity of electronic learning resources was discernible and most residents seemed to be satisfied with the existent system of evaluation. Significant differences (p < 0.05) among responses from India compared with those from other countries were found in terms of work hour regulations and subspecialty exposure. CONCLUSIONS: It is prudent that concerned authorities in LMICs recognize and address the deficiencies perceived by neurosurgery residents in their training programs. A determined effort in this direction would be endorsed and assisted by a host of international neurosurgical societies when it is felt that domestic resources may not be adequate. Quality control and close scrutiny of training programs should ensure that the interests of neurosurgical trainees are best served.

Multiple-site neural tube defects: embryogenesis with complete review of existing literature.

OBJECTIVE: Multiple-site neural tube defects (MNTDs) are very uncommon, with the predominant number of cases being reported in developing countries. The classic theory of neural tube closure fails to explain the occurrence of these defects. Multisite closure theory, first proposed in 1995, explains most of the occurrences with a few modifications specific to a few defects. In this paper, the authors endeavor to explain all the defects, along with their genetic and embryological bases, and to review the available literature and discuss their own experience in the management of these complex cases. METHODS: The authors retrospectively reviewed the data of all the patients treated surgically for MNTDs over that past 14 years. All possible demographic data, clinical details, and radiological imaging data were reviewed. In addition, surgical parameters, complications, and status at follow-up of more than 12 months were evaluated. All previously reported cases of MNTD were analyzed, and comparisons with the present series were made. RESULTS: A total of 3 major series (including the present one) on MNTDs have been from India. A total of 57 such cases (including those of the present series) have been reported in the available literature. While previous series reported a higher incidence of spinal defects, the present series had a higher rate of cephalic defects (55%). Among the reported cases, insertion of a ventriculoperitoneal shunt was necessary in 12 (26%), and only 4 patients were operated on in 2 stages. Neurological status at presentation dictated outcome. CONCLUSIONS: MNTDs are extremely rare, and their embryogenesis is different from that of single neural tube defects. Simultaneous repair of 2 or even 3 defects is possible in a single-stage surgery. The requirement of a shunt is uncommon, and complications following surgery are rare. Folic acid supplementation may reduce the incidence of defects.

Spinal Intramedullary Ganglioglioma in Children: An Unusual Location of a Common Pediatric Tumor.

Ganglioglioma is a common CNS tumor in children, mostly found in the temporal lobe, causing epilepsy. Spinal gangliogliomas are very rare, accounting for 1.1% of all intramedullary spinal tumors. The management principles and the need for adjuvant therapy are not yet well defined in this cohort. BRAF V600E mutation in spinal ganglioglioma has been described in a few series recently. In this report, we describe 3 children with spinal ganglioglioma at different locations, and their expression of BRAF V600E mutation and follow-up. In addition, we review the recent literature on pediatric spinal ganglioglioma management.

"Tailored" far lateral approach to anterior foramen magnum meningiomas - The importance of condylar preservation.

INTRODUCTION: Anterior and anterolaterally situated foramen magnum meningiomas are a technically complex subgroup of meningiomas. The need for an extensive exposure and bone work and their complex anatomy make them a difficult and challenging group of tumors to resect. The bone work has ranged from an extensive condylar resection to condylar preserving exposures. In this paper, we present our experience with condylar preserving or minimal condylar resection based approaches to these tumors. MATERIALS AND METHODS: All patients who underwent surgical resection of anterior and anterolaterally situated foramen magnum meningiomas were included in the analysis. The study period was more than 10 years from 2005 to 2015 at our institute; a tertiary referral centre in India. The records along with demographic profile, clinico-radiological features, surgical strategies, outcomes as well as mortality and morbidity were analysed. RESULTS: There were a total of 20 patients (9 males and 11 females) who were operated during the study period. The average age was 36.7 years. In 16 patients, gross-total or near-total resection could be achieved, four patients underwent subtotal resection. Eight patients had fresh morbidity in the form of new motor deficits, pseudomeningocele formation, worsening of the lower cranial nerve functions or post-operative adhesions leading to syrinx formation. The follow-up ranged from 6 months to 140 months. CONCLUSION: Foramen magnum meningiomas are an eminently treatable group of tumors. Condylar preservation provides a good visualization, while helping to preserve joint stability and in avoiding instrumental stabilization.

Surgically Managed Pediatric Intracranial Aneurysms: How Different Are They from Adult Intracranial Aneurysms?

PURPOSE: Intracranial aneurysms in children are rare compared to those in adults, and their causes, presentations, and outcomes also vary. Thus, they need to be studied intricately and as an independent entity. METHODS: We retrospectively reviewed intracranial saccular aneurysms in 44 children of <19 years of age who had been surgically treated during the last 30 years at our institute. We analyzed presentation, characteristics, size, multiplicity, cause, and eventual outcome, and compared these to the adult cases of aneurysms operated on during the same period. RESULTS: The commonest site of aneurysm was the internal carotid artery (ICA), in 47.7%. Follow-up was available for 38 (86.4%) children. The median duration of follow-up was 14 months (range 1-89 months). A favorable outcome was seen in 31 cases (81.6%) and an unfavorable outcome (including 1 death) in 7 (18.4%). CONCLUSION: Intracranial aneurysms in children present with subarachnoid hemorrhage in a good grade. ICA bifurcation aneurysms are the commonest sites of occurrence. Surgery is safe and effective, and children seem to have a better outcome.
