Abstract
BACKGROUND Giant aneurysms of the intracranial vertebral artery are very rare cerebrovascular lesions. Due to the rarity of these aneurysms, we know little about them. METHODS We performed a systematic review of the English literature by searching the PubMed database. The inclusion criteria were as follows: (a) the full text was available and (b) complete clinical data were available. RESULTS A total of 45 articles were identified, containing 53 patients (53 aneurysms). The patients were aged from 5 to 77 years (48.8 ± 20.8 years). Four patients receiving conservative treatment died. The remaining 49 patients were divided into the aneurysm removal group (n = 17) and the aneurysm reserve group (n = 32). The outcomes of the 49 treated cases could be obtained in 45 cases, 31 of which (68.9%, 31/45) had a Glasgow outcome scale score of 4-5. CONCLUSIONS It is still difficult to treat intracranial giant vertebral artery aneurysms, regardless of the treatment selected. Because of the malignant natural history, aggressive treatment is still advocated.

Reported incidence and treatment modalities of giant cerebral aneurysms in the pediatric population: A systematic review and illustrative case report. J Clin Neurosci 2021; 90:14-20. [PMID: 34275538 DOI: 10.1016/j.jocn.2021.03.045] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 03/04/2021] [Accepted: 03/30/2021] [Indexed: 02/04/2023]
Abstract
Giant intracranial aneurysms represent a complex pathology that pose challenges for management, especially in the pediatric population. With emerging endovascular techniques, combined endovascular and open surgical approaches may be a favorable alternative for complex cases. In this systematic review, we characterize the treatment modalities of giant aneurysms in the pediatric population and provide an update on the number of giant aneurysms reported in the literature by anatomic location. We conducted a literature search of PubMed, Embase, and Medline databases with the following terms: 'pediatric' AND 'giant' AND 'intracranial aneurysm.' Studies were included if data on treatment modality and aneurysm location were available for pediatric patients with giant intracranial aneurysms. The literature search yielded a total of 188 papers, with 82 pediatric patients from 33 articles ultimately meeting inclusion criteria. There were significantly more male than female patients (p = 0.011), with 52 and 29 respectively. Patients presenting with a ruptured aneurysm were significantly younger than patients presenting without rupture (p = 0.018), with a median age of 8.0 and 12.0 years, respectively. There were 45 giant aneurysms reported in the anterior circulation and 37 in the posterior circulation. Anterior aneurysms were most often treated with surgical approaches, while posterior aneurysms were typically treated with endovascular interventions (p = 0.002). Although combined surgical and endovascular approaches were the least frequently utilized, we suggest a combined approach may be particularly useful for patients with complex cases that require a management plan tailored to their needs.

Abstract
BACKGROUND Large intracranial dissecting aneurysm (IDA) in the anterior cerebral circulation is rare in children. There has been no consensus on the diagnosis and treatment for IDA in children.
CASE SUMMARY We report a 3-year-old boy with a large ruptured IDA in the right middle cerebral artery (16 mm × 14 mm). The IDA was successfully managed with clipping and angioplasty. Next-generation sequencing of the blood sample followed by bioinformatics analysis suggested that the rs78977446 variant of the ADAMTS13 gene is a risk for pediatric IDA. Three years after surgery, the boy was develop-mentally normal.
CONCLUSION Clipping and angioplasty are effective treatments for ruptured IDA in the anterior cerebral circulation. ADAMTS13 rs78977446 is a risk factor for pediatric IDA.

Abstract
Giant cerebral aneurysms are diagnosed more often in children than in adults. Treatment of giant aneurysms is carried out both by endovascular and microsurgical methods. Literature information on combination of microsurgical and endovascular operations of cerebral aneurysms at children is little. A clinical case of the combined treatment of a giant bicameral fusiform partially thrombosed aneurysm of the right vertebral artery at a 12-year-old patient and a literature review on this topic are presented. The patient underwent several complex neurosurgical interventions during two operations: 1) microsurgery including revascularization of the right posterior lower cerebellar artery, thrombectomy and trapping of the larger chamber of fusiform aneurysm of the right vertebral artery, and 2) endovascular, which consists in the installation of redirecting stent from the left vertebral artery to main artery. The uniqueness of the case which we presented lies in the fact that the tactics of stage combined treatment for a complex aneurysm at child was originally planned and successfully implemented. The treatment allowed to ensure a complete shutdown of aneurysm and to exclude postoperative cerebral complications.

Abstract
Vertebral artery (VA) aneurysms in the paediatric population are a rare but a serious condition. However, the epidemiology of paediatric VA aneurysms is poorly understood and there is little consensus on what constitutes the appropriate treatment. Although multiple treatment options are available, including surgery, endovascular approaches, coil embolization and parent artery occlusion, there is limited clinical evidence regarding which approach is most optimal. This review outlines the current literature and evidence outlining the epidemiology, presentation, pathogenesis and treatment of paediatric VA aneurysms.

Abstract
Vertebrobasilar (VB) intracranial dissecting aneurysms (IDAs) pose difficult therapeutic issues and are especially among the most difficult to manage surgically. There are, however, some cases where selective aneurysm obliteration by endovascular approach is impossible or is associated with an unacceptable risk of morbidity. This is particularly true when the aneurysm is dissecting, giant, or has a large neck. In such cases, surgical treatment may be the only alternative. Optimal management of these lesions is therefore challenging and treatment decisions have to be made on a case-by-case basis. Ideal treatment should be a complete surgical excision of the lesion; however, this procedure might only be possible after distal and proximal vessel wall occlusion which might not be tolerated by the patient depending on the location of the aneurysm. Therefore, formulation of recommendations concerning the surgical strategy remains still difficult due to inconsistency of surgical outcomes. The literature describing surgical strategy of VB IDAs is varying in quality and content, and many studies deal with only a few patients. In the presented review, the authors summarize the current knowledge on the incidence, pathogenesis, clinical presentation, and diagnostic procedures with special emphasis on surgical treatment of IDAs in posterior circulation.

Abstract
BACKGROUND Management of intracranial basilar dissecting aneurysms has been controversial and challenging, and surgical and conservative treatments usually have a bad prognosis. Our study aimed at evaluating the outcomes of endovascular treatment for these lesions and exploring the predictors of favorable outcome. METHODS We retrospectively reviewed 50 consecutive patients with basilar dissecting aneurysms from January 2006 to January 2013. Twenty-four patients underwent stent-assisted coiling whereas 26 patients underwent conservative treatment. Follow-up outcomes were evaluated using modified Rankin Scale (mRS) score. RESULTS Of the patients treated with stent-assisted coiling, 20 patients had a favorable outcome (mRS score, 0-1), post-treatment recurrence occurred in 3 patients, 1 had rebleeding, and 2 had no rebleeding. Of the patients treated with conservative therapy (observation or anticoagulation), 10 patients had an unfavorable outcome, 2 patients with ruptured aneurysms developed rebleeding, and 8 patients had poor outcome because of infarct progression. Stent-assisted coiling group had a more favorable outcome than the conservatively treated group (83.3% versus 55.2%, P = .019). Initial complete obliteration was related to the favorable outcome in endovascular-treated group (P = .042). Stent placement was the only independent predictor of favorable outcome in the logistic regression analysis (P = .030; odds ratio = 5.828; 95% confidence interval, 1.192-28.503). CONCLUSIONS Patients with basilar artery dissecting aneurysms treated with stent-assisted coiling had a more favorable outcome than the conservatively treated patients. Stent placement and initial complete occlusion were the favorable factors in patients with basilar dissecting aneurysm.

Abstract
UNLABELLED OBJECT.: Endovascular coiling and surgical clipping are viable treatment options of cerebral aneurysms. Outcome data of these treatments in children are limited. The objective of this study was to determine hospital mortality and complication rates associated with surgical clipping and coil embolization of cerebral aneurysms in children, and to evaluate the trend of hospitals' use of these treatments. METHODS The authors identified a cohort of children admitted with the diagnoses of cerebral aneurysms and aneurysmal subarachnoid hemorrhage from the Kids' Inpatient Database for the years 1998 through 2009. Hospital-associated complications and in-hospital mortality were compared between the treatment groups and stratified by aneurysmal rupture status. A multivariate regression analysis was used to identify independent variables associated with in-hospital mortality. The Cochrane-Armitage test was used to assess the trend of hospital use of these operations. RESULTS A total of 1120 children were included in this analysis; 200 (18%) underwent aneurysmal clipping and 920 (82%) underwent endovascular coiling. Overall in-hospital mortality was higher in the surgical clipping group compared with the coil embolization group (6.09% vs 1.65%, respectively; adjusted odds ratio [OR] 2.52, 95% CI 0.97-6.53, p = 0.05). The risk of postoperative stroke or hemorrhage was similar between the two treatment groups (p = 0.86). Pulmonary complications and systemic infection were higher in the surgical clipping population (p < 0.05). The rate of US hospitals' use of endovascular coiling has significantly increased over the years included in this study (p < 0.0001). Teaching hospitals were associated with a lower risk of death (OR 0.13, 95% CI 0.03-0.46; p = 0.001). CONCLUSIONS Although both treatments are valid, endovascular coiling was associated with fewer deaths and shorter hospital stays than clip placement. The trend of hospitals' use of coiling operations has increased in recent years.

Abstract
Background: Intracranial giant vertebral artery aneurysms are extremely rare in the pediatric population and are associated with significant morbidity and mortality. The present report describes a case of a pediatric patient with giant vertebral artery aneurysm who presented with intracranial mass effect. This patient was successfully treated with endovascular parent artery occlusion and coil embolization. Case Description: A 7-year-old girl presented with tetraparesis, ataxia, dysphagia, and dysphonia. Cerebral angiography revealed intracranial giant aneurysm arising from the right vertebral artery. The patient underwent endovascular parent artery occlusion alone to facilitate aneurysmal thrombosis as an initial treatment. This was done to avoid a coil mass effect to the brainstem. However, incomplete thrombosis occurred in the vicinity of the vertebral artery union. Therefore, additional coil embolization for residual aneurysm was performed. Two additional coil embolization procedures were performed in response to recurrence. Mass effect and clinical symptoms gradually improved, and the patient had no associated morbidity or recurrence at 2 years after the last fourth coil embolization. Conclusion: Intracranial giant vertebral artery aneurysms are rare and challenging in pediatric patients. Staged endovascular strategy can be a safe and effective treatment option.

Abstract
OBJECTIVES Intracranial aneurysms are rare in children although giant aneurysms more commonly occur in adolescence. The aims of our study were to perform an extensive review of the literature over the past two decades and assess intracranial aneurysm management. METHODS Based on a Pubmed search, we carried out a review of the literature from 1990 to 2012 regarding giant intracranial aneurysms diagnosed in the paediatric population. This descriptive study concerned clinical presentation, cerebral aneurysm characteristics, therapeutic management procedures and outcome. RESULTS Forty-six cases were reported in 31 papers. The male/female sex ratio was 1.15, the clinical presentation was a tumour mass syndrome in 56.6%, followed by rupture in 30.4%. The aneurysm location was the posterior circulation in 41.3%, and microsurgical treatment (52.2%) predominated over endovascular coiling (28.3%). CONCLUSION To date, no evidence-based medicine recommendation has been accepted for the management of rare intracranial aneurysms. Each reported patient was the object of a multidisciplinary clinical decision. Management of this challenging pathology should be performed on a case-to-case basis.

Abstract
PURPOSE Iatrogenic aneurysms are very rare in children. Characteristic clinical manifestations are variable and asymptomatic course is possible especially for fusiform dilatation of internal carotid artery. Even though radiological diagnosis is easy, the management of iatrogenic intracranial aneurysm is still a subject for discussion. METHODS Fusiform dilatations of internal carotid artery were diagnosed on three pediatric patients during follow-up imaging after primary surgery for suprasellar-parasellar tumor. All patients were asymptomatic. Conservative treatment was proposed because the lesion did not show any progression in subsequent examinations. Patients are stable under conservative treatment. CONCLUSIONS Iatrogenic aneurysm may have an unusual presentation and their therapy still remains unclear. Fusiform dilatation of internal carotid artery rarely causes symptoms and there is no published paper of subarachnoid bleeding. Treatment would be difficult, since the main arterial branches arise from the dilated carotid segment. Conservative treatment is a choice only if aneurysm has no progression or in case of spontaneous healing. Intervention should be performed only in case of progression or if the aneurysm becomes symptomatic.

Abstract
BACKGROUND AND PURPOSE Children with brain aneurysms may be at higher risk than adults to develop new or enlarging aneurysms in a relatively short time. We sought to identify comorbidities and angiographic features in children that predict new aneurysm formation or enlargement of untreated aneurysms. MATERIALS AND METHODS Retrospective analysis of the University of California-San Francisco Pediatric Aneurysm Cohort data base including medical records and imaging studies was performed. RESULTS Of 83 patients harboring 114 intracranial aneurysms not associated with brain arteriovenous malformations or intracranial arteriovenous fistulas, 9 (8.4%) developed new or enlarging brain aneurysms an average of 4.2 years after initial presentation. Comorbidities that may be related to aneurysm formation were significantly higher in patients who developed new aneurysms (89%) as opposed to patients who did not develop new or enlarging aneurysms (41%; RR, 9.5; 95% CI, 1.9%-48%; P = .0099). Patients with multiple aneurysms at initial presentation were more likely than patients with a single aneurysm at presentation to develop a new or enlarging aneurysm (RR, 6.2; 95% CI, 2.1%-185; P = .0058). Patients who initially presented with at least 1 fusiform aneurysm were more likely to develop a new or enlarging aneurysm than patients who did not present with a fusiform aneurysm (RR, 22; 95% CI, 3.6%-68%; P = .00050). Index aneurysm treatment with parent artery occlusion also was associated with higher risk of new aneurysm formation (RR, 4.2; 95% CI, 1.3%-13%; P = .024). New aneurysms did not necessarily arise near index aneurysms. The only fatality in the series was due to subarachnoid hemorrhage from a new posterior circulation aneurysm arising 20 months after index anterior circulation aneurysm treatment in an immunosuppressed patient. CONCLUSIONS Patients who presented with a fusiform aneurysm had a significantly greater incidence of developing a new aneurysm or enlargement of an index aneurysm than did those who presented with a saccular aneurysm. In our patient cohort, 8 of the 9 children who eventually developed new or enlarging brain aneurysms initially presented with fusiform aneurysm morphology. Other comorbidities or multiple aneurysms were also common in these patients at initial presentation.

Abstract
Although the general principles of endovascular aneurysm treatment in adults hold true in children, these young patients pose unique challenges: small anatomy, longer life expectancy, associated conditions and morphological characteristics of the aneurysms. Few publications in the literature address the role of endovascular treatment for pediatric aneurysms; including series by Agid et al. (2005) (1) revisiting the Toronto series, Lasjaunias et al. (2005) (2) updating the Bicêtre series and Sanai et al (2006) (8) presenting the San Francisco series. In their conclusions, the authors of the former two publications favored endovascular treatment over microsurgery. On the other hand, the authors of the latter publication favored microsurgery over endovascular treatment. The authors reviewed Louisiana State University experience regarding endovascular treatment of pediatric aneurysms focusing on outcomes. A retrospective chart review was performed of children under 18, who underwent endovascular treatment for intracranial aneurysms between 2000 and 2009 in our institution. Twelve patients harboring seventeen aneurysms were identified. The patients ranged in age from seventeen months to seventeen years. Complete aneurysm obliteration following endovascular treatment was around 95%. Our results showed unique features for pediatric aneurysms when compared to adult aneurysms. No intra operative mortality was recorded. One aneurysm recurred (5% recurrence rate among total number of aneurysms). In this case, six months after treatment, a control angiogram showed that the coils were displaced toward the dome of the aneurysm. This recurrence occurred before the introduction of the hydro coils. One patient died during the post intervention period (8% occurrence rate among total number of patients). Outcomes were better in anterior circulation aneurysms than in posterior circulation lesions. We had no mortality, morbidity or disability in the anterior circulation aneurysm group. In the posterior circulation group, there was one death representing 14% of the nine patients with aneurysms in this group. One recurrence occurred in the posterior circulation group representing 11% of the nine aneurysms in this group. Follow-up of all patients ranged from two to eight years. Endovascular treatment of pediatric intracranial aneurysm is safe and efficacious. Endovascular treatment in many instances provides less morbidity and mortality for treatment of pediatric aneurysms in inaccessible or eloquent locations than microsurgical clipping. The result of endovascular treatment depends on the location of the aneurysms and the underlying pathology. We advocate a multidisciplinary approach when choosing the therapeutic modality for treatment of pediatric aneurysms.

Abstract
OBJECT The purpose of this study is to analyze the clinical presentation, morphological characteristics, angio-architecture, and outcome of vertebrobasilar dissection (VBD) in the pediatric population. METHODS The authors retrospectively reviewed 29 consecutive cases involving children younger than 16 years of age who were diagnosed with symptomatic VBDs. Data were gathered with respect to the patient's age, sex, clinical history, associated underlying disease, and symptoms (headache, vertigo) as well as the location of the dissection and the imaging appearance. RESULTS The patients' mean age was 8.24 years (range 2 months-15 years). There was an overall 3:1 male predominance, although among children older than 8 years, girls and boys were similarly affected. Hemorrhagic dissections occurred in 10 of 29 cases. In nonhemorrhagic dissections, stroke occurred in 16 cases, with the most common presenting symptoms being headaches and vertigo; in the other 3 cases, mass effect due to a chronic dissecting aneurysm was present. In 7 children an underlying vessel wall disease was found. The location of the dissection was extradural in 11 cases and intradural in the remainder. There was no preference with respect to side. The basilar artery was affected in 9 patients. CONCLUSIONS The imaging appearance and clinical presentation of symptomatic VBDs in the pediatric population differs from that in adults. Boys are more often affected, especially at younger ages, and hemorrhagic presentation is more common, presumably owing to the fact that the basilar artery is more commonly involved. Depending on the pathogenetic mechanism underlying the dissection, different clinical symptoms will evolve, necessitating individually tailored treatment.

Abstract
PURPOSE Intracranial aneurysms are relatively rare in the pediatric population. The objective of this study was to highlight the clinical and radiological features and the therapeutic outcome and clarify the choice of therapeutic strategies for pediatric intracranial aneurysms. MATERIALS AND METHODS Twenty-four consecutive children (age <or=14 years) who were diagnosed and treated for intracranial aneurysms in our institute in the last 23 years were included in this study. RESULTS There were nine (36%) patients with posterior circulation aneurysms and eight (32%) with giant aneurysms. Eleven (46%) patients presented with subarachnoid hemorrhage. Fifteen patients underwent endovascular treatment, and four received microsurgical therapy. Five patients were treated conservatively. Ninety-two percent (n=22) of the patients showed favorable outcomes. CONCLUSIONS Pediatric intracranial aneurysms differ in many ways from those in adults: male predominance; high incidence of giant, dissecting, and fusiform aneurysms; high incidence of aneurysms in the posterior circulation; high incidence of spontaneous thrombosis; better Hunt-Hess grades at presentation; and better therapeutic outcome. For children with intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. For many complex aneurysms, endovascular therapy was the best choice.

Abstract
SUMMARY Aneurysms in children are rare.We describe a large spontaneous dissecting aneurysm of the posterior cerebral artery. The clinical presentation was characterized by headache as the sole symptom due to a mass effect leading to hydrocephalus. Acute treatment with a temporary ventricular shunt was followed by occlusion of the aneurysm via an endovascular approach leading to a complete recovery of the patient.

Abstract
Intracranial aneurysms in young infants are extremely rare, with few published reports on the etiology, evaluation, treatment strategies, and follow-up of this condition in this population. The authors report the case of a traumatic dissecting aneurysm at the vertebrobasilar junction (VBJ) in a 3-month-old infant caused by nonaccidental trauma. Therapeutic occlusion of the VBJ was contemplated, but coil embolization of the main aneurysm sac proved feasible, and anticoagulation and antiplatelet agents were initiated. The patient made a full neurological recovery, and follow-up studies demonstrated stable aneurysm occlusion. Management and follow-up strategies for this challenging condition are discussed.

Abstract
SUMMARY Dissecting aneurysms involving the basilar artery (BA) are lesions with significant morbidity and mortality. Their management is controversial and often difficult. There is no generally approved strategy. Two cases of huge dissections involving the BA presented with subarachnoid hemorrhage in one case and mass effect in both cases. The dissection of case 1 involved the upper two thirds of the BA distal to the anterior inferior cerebellar arteries (AICA). Another dissection of case 2 involved the bilateral vertebral arteries (VA) distal to bilateral PICA and extended to upper third of the BA. After making a basket with coils inside the pseudoaneursym, proximal dissection was totally occluded in case 1. Dissection on the bilateral VA distal to the bilateral PICA and proximal BA was occluded in case 2 with a small residual dissection on the left VA. Case 1 had an excellent recovery with a durable image and clinical result. But recanalization and regrowth occurred in case 2, which might have originated from the residual dissection on the left VA, induced acute mass effect and sudden coma six weeks after the initial treatment. The residual and regrown dissection had to be occluded in a second intervention. The patient died two days later. BA occlusion is safe and efficient for dissections involving the BA as in our case and the literature. Proximal occlusion might be enough for huge and long lesions like ours. It seems that completely dense packing of proximal dissection is the key point to prevent recanalization.

Abstract
Childhood aneurysms have special characteristics different from adults' aneurysms. Their features were found to significantly differ from aneurysms in adults especially in their gender prevalence, location, morphology and underlying etiology. Treatment options include both surgical and endovascular methods. Whenever possible, endovascular treatment for pediatric aneurysms is the recommended approach, since it offers both reconstructive and deconstructive techniques, durable results and better clinical outcome.

Abstract
INTRODUCTION Intracranial aneurysms in the paediatric population are uncommon, accounting for 2% to 6% of all aneurysms, and spontaneous arterial dissection is rarely reported as the cause of aneurysms in children, especially in the posterior cerebral artery. METHODS Two cases of paediatric spontaneous posterior cerebral artery dissecting aneurysms are reported, one in a 33-month-old male child presenting with aneurysmal rupture and subarachnoid haemorrhage and the other in a 9-year-old boy with an unruptured aneurysm. RESULTS The first child was successfully treated by endovascular parent vessel occlusion without neurological deficit and in the second a spontaneous thrombosis of the aneurysm and its parent artery occurred associated with hydrocephalus and a favourable outcome. CONCLUSION Dissecting aneurysms are dynamic lesions with variable and unpredictable evolution and close follow-up and/or early treatment is warranted. Spontaneous arterial dissection is a rare, probably still under-recognized, cause of intracranial aneurysms that may be responsible for a significant number of aneurysms and spontaneous aneurysmal thromboses in children.
