Abstract
Pediatric cerebral aneurysms are rare, and pediatric anterior choroidal artery aneurysms are very rarely reported. A 14-month-old male with no personal or family history of connective tissue disorders or Moyamoya disease presented with a right temporal intracerebral hemorrhage with intraventricular extension. CTA was negative for vascular pathology, but digital subtraction angiography revealed an anterior choroidal artery aneurysm that was successfully coiled. This case underscores the importance of performing digital subtraction angiography in children presenting with intracerebral hemorrhage concerning for vascular pathology even if non-invasive vascular imaging is negative.

Ruptured Middle Cerebral Artery Aneurysm in an Infant: Case Report and Literature Review. NMC Case Rep J 2023; 10:177-183. [PMID: 37465251 PMCID: PMC10351959 DOI: 10.2176/jns-nmc.2022-0369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 03/27/2023] [Indexed: 07/20/2023] Open
Abstract
Intracranial aneurysms (IA) in infants are reportedly rare at 0.5% to 4.5% of all aneurysms. Furthermore, subarachnoid hemorrhage in infants younger than three months are even rarer as it has been reported in approximately 20 cases only till date. A 3-month-old infant with seizures and impaired consciousness was admitted to our hospital. Three-dimensional computed tomography angiography (3D-CTA) revealed a dissecting aneurysm with a maximum diameter of 13 mm in the right M2. Internal trapping using detachable coil were successfully performed, following which he was discharged without significant neurological deficit after one month of onset. Thus, we have reported a rare case of a large ruptured dissecting IA in a 3-month-old infant, in the right middle cerebral artery (MCA), successfully treated with an endovascular therapy, along with a literature review.

Predictive validity of the prognosis on admission aneurysmal subarachnoid haemorrhage scale for the outcome of patients with aneurysmal subarachnoid haemorrhage. Sci Rep 2023; 13:6721. [PMID: 37185953 PMCID: PMC10130082 DOI: 10.1038/s41598-023-33798-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 04/19/2023] [Indexed: 05/17/2023] Open
Abstract
This multicentre prospective cohort study aimed to compare the accuracy of the PAASH, WFNS, and Hunt and Hess (H&H) scales in predicting the outcomes of adult patients with aneurysmal SAH presented to three central hospitals in Hanoi, Vietnam, from August 2019 to June 2021. Of 415 eligible patients, 32.0% had a 90-day poor outcome, defined as an mRS score of 4 (moderately severe disability) to 6 (death). The PAASH, WFNS and H&H scales all have good discriminatory abilities for predicting the 90-day poor outcome. There were significant differences in the 90-day mean mRS scores between grades I and II (p = 0.001) and grades II and III (p = 0.001) of the PAASH scale, between grades IV and V (p = 0.026) of the WFNS scale, and between grades IV and V (p < 0.001) of the H&H scale. In contrast to a WFNS grade of IV-V and an H&H grade of IV-V, a PAASH grade of III-V was an independent predictor of the 90-day poor outcome. Because of the more clearly significant difference between the outcomes of the adjacent grades and the more strong effect size for predicting poor outcomes, the PAASH scale was preferable to the WFNS and H&H scales.

Risk factors for intracranial aneurysm rupture in pediatric patients. Acta Neurochir (Wien) 2022; 164:1145-1152. [PMID: 34415443 DOI: 10.1007/s00701-021-04957-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Accepted: 07/28/2021] [Indexed: 02/05/2023]
Abstract
BACKGROUND Intracranial aneurysm (IA) rupture in pediatric patients is a rare but fatal condition. Although risk factors for aneurysm rupture in adults have been well documented, they remain unknown in pediatric patients. METHODS Data for 94 pediatric patients with IAs were retrospectively analyzed. The patients were divided into ruptured and unruptured groups. Risk factors for aneurysm rupture were analyzed through univariable and multiple logistic regression analyses. Typical patients with risk factors were described. RESULTS Univariable analyses showed that the unruptured group had significantly higher percentages of giant aneurysms (43.2% vs 12.3%, P = 0.002), wide-neck aneurysms (67.6% vs 29.8%, P = 0.001), and aneurysms located in the internal carotid artery (40.5% vs 3.5%, P < 0.001), while the ruptured group had significantly higher percentages of patients younger than 5 years old (28.1% vs 5.4%, P = 0.013) and aneurysms located in the anterior cerebral artery (24.6% vs 5.4%, P = 0.032), posterior cerebral artery (14.0% vs 0%, P = 0.045), and distal arterial region (DAR) (46.8% vs 27.0%, P < 0.001). Multiple logistic regression analysis confirmed that age 0-5 years (OR = 6.844, P = 0.042) and IAs located in the DAR (OR = 4.162, P = 0.029) were independently related to an increased risk of rupture. Wide-necked aneurysms (OR = 0.235, P = 0.047) were independently associated with a lower risk of rupture. CONCLUSIONS Among pediatric patients, age younger than 5 years and lesions located in the DAR are independent risk factors for IA rupture, while an IA with a wide neck acts as a protective factor.

Ruptured AComA aneurysm and asymptomatic bilateral ACA vasospasm in an infant: surgical case report. Childs Nerv Syst 2022; 38:633-641. [PMID: 34021372 DOI: 10.1007/s00381-021-05215-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Accepted: 05/13/2021] [Indexed: 11/27/2022]
Abstract
Intracranial aneurysms (IAs) are localized dilations of the cerebral vasculature, representing the leading cause for non-traumatic subarachnoid hemorrhage and an important source of morbidity and mortality. Despite it being a frequent pathology and most often diagnosed incidentally, IAs in infants are a very rare occurrence, and the ruptured variant is exceptional. A 4-month-old boy with a negative family history was brought to our department because of several episodes of incoercible vomiting and fever. Upon examination, the child was somnolent, without any noticeable deficit. Transfontanellar ultrasonography and CT angiography revealed a ruptured aneurysm of the anterior communicating artery (AComA), whereas the pre-clipping MRI showed thin, almost angiographically invisible anterior cerebral arteries (ACAs) on both sides due to vasospasm. We intervened surgically by placing an external ventricular shunt in an emergency setting, followed by clipping of the IA in a delayed manner. The child was discharged a month after admission with no deficit, despite the paradoxical aspect of the ACA. Ruptured IAs can be safely treated via microsurgery, even in infants. However, this requires a great amount of experience and surgical expertise. Furthermore, the lack of proper management would most likely result in a severe deficit in the long term. Lastly, the lack of visibility of the ACA on angiographic studies may not have neurological consequences if they occur in this age group.

Clinical characteristics and factors relating to poor outcome in patients with aneurysmal subarachnoid hemorrhage in Vietnam: A multicenter prospective cohort study. PLoS One 2021; 16:e0256150. [PMID: 34388213 PMCID: PMC8362943 DOI: 10.1371/journal.pone.0256150] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Accepted: 07/30/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND The prevalence of risk factors for poor outcomes from aneurysmal subarachnoid hemorrhage (SAH) varies widely and has not been fully elucidated to date in Vietnam. Understanding the risk and prognosis of aneurysmal SAH is important to reduce poor outcomes in Vietnam. The aim of this study, therefore, was to investigate the rate of poor outcome at 90 days of ictus and associated factors from aneurysmal SAH in the country. METHODS We performed a multicenter prospective cohort study of patients (≥18 years) presenting with aneurysmal SAH to three central hospitals in Hanoi, Vietnam, from August 2019 to August 2020. We collected data on the characteristics, management, and outcomes of patients with aneurysmal SAH and compared these data between good (defined as modified Rankin Scale (mRS) of 0 to 3) and poor (mRS, 4-6) outcomes at 90 days of ictus. We assessed factors associated with poor outcomes using logistic regression analysis. RESULTS Of 168 patients with aneurysmal SAH, 77/168 (45.8%) were men, and the median age was 57 years (IQR: 48-67). Up to 57/168 (33.9%) of these patients had poor outcomes at 90 days of ictus. Most patients underwent sudden-onset and severe headache (87.5%; 147/168) and were transferred from local to participating central hospitals (80.4%, 135/168), over half (57.1%, 92/161) of whom arrived in central hospitals after 24 hours of ictus, and the initial median World Federation of Neurological Surgeons (WFNS) grading score was 2 (IQR: 1-4). Nearly half of the patients (47.0%; 79/168) were treated with endovascular coiling, 37.5% (63/168) were treated with surgical clipping, the remaining patients (15.5%; 26/168) did not receive aneurysm repair, and late rebleeding and delayed cerebral ischemia (DCI) occurred in 6.1% (10/164) and 10.4% (17/163) of patients, respectively. An initial WFNS grade of IV (odds ratio, OR: 15.285; 95% confidence interval, CI: 3.096-75.466) and a grade of V (OR: 162.965; 95% CI: 9.975-2662.318) were independently associated with poor outcomes. Additionally, both endovascular coiling (OR: 0.033; 95% CI: 0.005-0.235) and surgical clipping (OR: 0.046; 95% CI: 0.006-0.370) were inversely and independently associated with poor outcome. Late rebleeding (OR: 97.624; 95% CI: 5.653-1686.010) and DCI (OR: 15.209; 95% CI: 2.321-99.673) were also independently associated with poor outcome. CONCLUSIONS Improvements are needed in the management of aneurysmal SAH in Vietnam, such as increasing the number of aneurysm repairs, performing earlier aneurysm treatment by surgical clipping or endovascular coiling, and improving both aneurysm repairs and neurocritical care.

Intracranial aneurysms in pediatric population: a two-center audit. Childs Nerv Syst 2021; 37:2567-2575. [PMID: 33876302 DOI: 10.1007/s00381-021-05151-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Accepted: 03/29/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVE Intracranial aneurysms (IA) in children are rare, accounting for less than 5% of all IA. Due to their scarcity, the epidemiology is poorly understood and differs from adults in term of clinical presentation, size, location, and origin. Consequently, the treatment strategies are specific and cannot be only based on data from adult series. The aim of our study was to report the characteristics, management, and outcomes of children treated for IA in two university hospitals located in Normandy (France) over the last 17 years and to perform a literature review of this rare pathology. METHODS This retrospective study included 18 consecutive children (< 18 years old) admitted with cerebral aneurysm treated in two neurosurgery departments in Normandy, from 2001 to 2018. Computerized tomography and cerebral angiography established the diagnosis. Both endovascular and surgical procedures were discussed in all cases. Data focused on clinical condition at admission, characteristics of the IA, choice of the treatment modalities, and complications. The outcome at follow-up is based on Glasgow outcomes scale (GOS) at 1 year. RESULTS During the study period, 18 children (mean age: 12.6 years; sex ratio male/female: 2.3) were admitted with 21 IA. Aneurysms had a mean size of 13.6 mm with 4 giant aneurysms and were mostly located in the anterior circulation (16/21). Clinical presentations at onset were sudden symptoms related to a subarachnoid hemorrhage in 13 patients, headaches in 4 patients with giant aneurysm, and asymptomatic in one patient. Among the 13 patients with ruptured IA, 6 presented in poor preoperative condition (Hunt and Hess Grade ≥ 4). Treatment modalities consisted in embolization in 9 patients and surgery in 9 patients including 2 by-pass surgeries in fusiform aneurysms. Complications were similar in the two groups, but two cases of recanalization were observed in the endovascular group. At 1 year of follow-up, 14 children were in good condition (GOS Score > 4) and one died. Three children presented associated IA treated by the same technique as initial aneurysm. CONCLUSIONS Pediatric aneurysm is a different pathology compared with adults, occurring more frequently in male population with a higher proportion of giant aneurysms and aneurysms located in the internal carotid bifurcation. The use of endovascular techniques has progressed in the last years, but surgery was proposed for half of our population.

Ruptured Intracranial Aneurysm in a Neonate: Case Report and Review of the Literature. World Neurosurg 2020; 140:219-223. [PMID: 32407915 DOI: 10.1016/j.wneu.2020.05.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 05/01/2020] [Accepted: 05/02/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Intracranial aneurysms (IAs) are exceptional in neonates accounting for less than 2% of all IAs occurring during the first decade of life. Little is known about this pathology in this specific population. Because of its scarcity and this specific age at onset, the treatment of IA in neonates is challenging. We describe a rare case of aneurysmal subarachnoid hemorrhage in a neonate and review the current literature. CASE DESCRIPTION A 21-day-old boy was admitted for hypotonia, vomiting, and seizures. Computed tomography scan revealed a subarachnoid hemorrhage in the sylvian fissure, a frontoparietal subdural hematoma, a left middle cerebral artery (MCA) aneurysm with a diameter of 11 mm, and an infarct of the MCA frontal region. He was successfully treated with endovascular coiling, neuroprotection, and antiepileptic drugs. Immediate postoperative magnetic resonance imaging showed a good aneurysm occlusion without any further ischemia. The outcome was favorable with extubation at day 10. At follow-up, the child experienced normal psychomotor development with no motor deficit. CONCLUSIONS Ruptured IAs in neonates are rare. Subarachnoid hemorrhage is the most common presentation. Intracranial aneurysms are frequently larger than 10 mm and located on the MCA. The treatment could be surgical or endovascular depending on the characteristics of the aneurysm. There is no recommendation concerning the prevention or treatment of vasospasm in neonates.

Abstract
Objective: There is a relative lack of literature on long-term aneurysm recurrence and de novo aneurysm formation following surgical treatment of unruptured intracranial aneurysms. This retrospective single-center cohort study, therefore, analyzes the incidence of aneurysm recurrence, and the incidence of de novo aneurysms formation in patients with at least 10yrs of radiological follow-up. The data are put into the context of a systematic review of the literature.Methods: Patients that underwent surgical treatment of an unruptured intracranial aneurysm at the Basel University Hospital were retrospectively identified. The rate of recurrent or de novo aneurysm formation was assessed for all patients with imaging follow-up ≥10yrs. A systematic review including studies with a mean follow-up period of ≥10yrs was then performed.Results: A total of 95 patients had undergone surgical treatment of an unruptured intracranial aneurysm between 1994 and 2008. Twenty-one patients (22.1%) had available imaging follow-up ≥10yrs (mean: 13.1yrs). In these patients, aneurysm recurrence and de novo aneurysm formation were equally found in 23.8% (n = 5; 1.8%/yr). There was no case of aneurysm rupture from a recurrent or a de novo aneurysm. The systematic literature review covered a combined cohort of 1778 patients over a mean follow-up period of 14.0yrs. In this cohort, the aneurysm recurrence rate was 16.4% (0.7%/yr), and the rate of de novo aneurysm formation was 6.2% (0.4%/yr).Discussion: Despite some discrepancy regarding the incidence, both cohorts show a non-negligible long-term risk of aneurysm recurrence and de novo aneurysm formation, which warrants life-long imaging follow-up.Abbreviations: SD: standard deviation; DSA: digital subtraction angiography; CTA: computed tomography angiography; MRA: magnetic resonance angiography; MCA: middle cerebral artery; ACA: anterior cerebral artery; ACommA: anterior communicating artery; ICA: internal carotid artery; ADPKD: autosomal dominant polycystic kidney disease; MeSH: Medical Subject Headings.

Abstract
BACKGROUND The National Institute of Neurological Disorders and Stroke (NINDS) Common Data Elements (CDEs) have been generated to standardize and define terms used by the scientific community. The widespread use of these CDEs promotes harmonized data collection in clinical research. The aim of the NINDS Unruptured Intracranial Aneurysms (UIA) and Subarachnoid Hemorrhage (SAH), and Subject Characteristics working group (WG) was to identify, define, and classify CDEs describing the characteristics of patients diagnosed with an UIA and SAH. Thus, "Participant/Subject characteristics" is a set of factors defining a population of selected individuals and allowing comparisons with a reference population and overtime. METHODS Based on standard terms defined by the United States' Census Bureau, CDEs previously defined by several (Stroke, Epilepsy and Traumatic Brain Injury) NINDS CDE working groups literature and expert opinion of the WG, the "Participant/Subject characteristics" domain has been defined. RESULTS A set of 192 CDEs divided in 7 subsections: demographics (8 CDEs), social status (8 CDEs), behavioral status (22 CDEs), family and medical history (144 CDEs), pregnancy and perinatal history (8 CDEs), history data source reliability (3 CDEs), and prior functional status (3 CDEs) was defined. SAH is characterized by 6 core elements, all classified in the "Participant/Subject characteristics" domain. Four exploratory elements out of the 39 for SAH overall are in the "Participant/Subject characteristics" domain, and all remaining 182 CDEs in the "Participant/Subject characteristics" domain are classified as Supplemental-Highly Recommended elements. CONCLUSIONS These CDEs would allow the development of best practice guidelines to standardize the assessment and reporting of observations concerning UIA and SAH.

Abstract
Objective Intracranial aneurysms are not common in young age patients. We sought to find the characteristics of the intracranial aneurysms in patients under 20 years of age.
Methods We reviewed 23 consecutive patients ≤20 years of age treated for their intracranial aneurysms during the period from 1995 to 2017. From medical records and imaging studies, we gathered data on age, sex, presentation, associated medical condition, location and characteristics of aneurysms, treatment and clinical outcomes.
Results The patients’ ages ranged from 13 months to 20 years (median, 14 years). There were 16 males and seven females (male to female ratio, 2.3 : 1) with 31 aneurysms. Clinical presentations included sudden severe headache in 61%, followed by altered mentality in 17% and seizure in 17%. More than one-fourth patients had specific medical conditions related to the development of the cerebral aneurysms. The majority of aneurysms occurred in the anterior circulation (71%), and were saccular (71%). There were each three patients with false aneurysms (13%) and giant aneurysms (13%), and only one patient with multiple aneurysms (4%). We treated 22 patients : 21 aneurysms with the endovascular methods, three with open surgery, and one with combined treatment. Good functional outcome could be achieved in 86% during the follow-up period.
Conclusion In this series, the young-age patients with intracranial aneurysms were characterized by male predominance, related specific medical conditions, low incidence of multiple aneurysms, high incidence of giant aneurysms and good functional outcome after treatment.

Abstract
Objective: Studies on pediatric severe acquired brain injury (sABI) outcomes focused mostly on single etiologies, not clarifying the independent role of clinical factors, and scantly explored inter-dependence between variables. We assessed associations of clinical factors at admission with essential outcomes, controlling for inter-dependence and sABI etiology. Methods: We reviewed the clinical records of 280 patients with traumatic and 292 with non-traumatic sABI, discharged from intensive care to pediatric neurological rehabilitation. We analyzed the distribution of clinical factors based on sABI etiology; conducted a factor analysis of variables; built multivariate models evaluating the associations of variables with death, persistent vegetative states, duration of coma, GOS outcome, length of stay. Results: We described the study sample. Factor analysis of inter-dependence between GCS, time before rehabilitation, dysautonomia, device use, produced the indicators "injury severity" and "neurological dysfunction", independent from sABI etiology, age, sex, and admittance GOS. Multivariate analyzes showed that: coma duration, GOS outcome, and length of stay, which may depend on rehabilitation courses, were directly associated with injury severity, neurological dysfunction, and patients' age; death and persistent vegetative states were also associated with etiology. Conclusion: Future studies should analyze larger cohorts and investigate mechanisms linking specific etiologies and patients' age with outcomes.

Abstract
BACKGROUND Our aim was to report the long-term clinical and imaging outcomes of ≤15-year-old children treated for ruptured or symptomatic cerebral aneurysms and to identify prognostic factors for clinical outcome, recurrence, and rebleeding. METHODS We retrospectively identified all pediatric cases of cerebral aneurysm from 2000 to 2015 and then prospectively evaluated long-term occlusion using brain MRI and clinical outcome measures: outcome was considered favorable if King's Outcome Scale for Childhood Head Injury score was ≥5. We performed univariate analysis and logistic binary regression to identify variables associated with clinical and imaging outcomes. RESULTS Fifty-one children (aged 8.5 ± 1.1 years [mean ± SD], with 37 ruptured and 14 symptomatic aneurysms) were included, and endovascular treatments (84%) or microsurgical procedures (16%) were performed. Despite a 19.6% death rate, at a mean follow-up of 8.3 years, 35 children (68.6%) had a favorable outcome. Annual bleeding and aneurysm recurrence rates were 1.4% ± 1.1% and 2.6% ± 1.8%, respectively. Cerebral ischemia, whether initial or delayed within the first month, was predictive of poor clinical outcome in multivariate analysis (odds ratio: 25; 95% confidence interval: 0.43-143; P < .0001), whereas aneurysm size >5 mm was the only factor associated with recurrence (odds ratio: 14.6; 95% confidence interval: 2.4-86.1; P = .003). CONCLUSIONS Two-thirds of studied ≤15-year-old children suffering from ruptured or symptomatic cerebral aneurysms had long-term favorable outcome. Annual bleeding and aneurysm recurrence rates have shown to be low after endovascular or surgical treatment. Long-term imaging follow-up helps to depict aneurysm recurrence or de novo aneurysm formation and to prevent rebleeding.

Abstract
BACKGROUND Pediatric intracranial aneurysms (IAs) are rare. Compared with adult IAs, they are more commonly giant, fusiform, or dissecting. Treatment often proves more complex, and recurrence rate and de novo aneurysmogenesis incidence are higher. A consensus regarding the most appropriate algorithm for following pediatric IAs is lacking. METHODS We sought to generate recommendations based on the reported experience in the literature with pediatric IAs through a thorough review of the PubMed database, discussion with experienced neurointerventionalists, and our own experience. RESULTS Digital subtraction angiography (DSA) was utilized immediately post-operatively for microsurgically-clipped and endovascularly-treated IAs, at 6-12 months postoperatively for endovascularly-treated IAs, and in cases of aneurysmal recurrence or de novo aneurysmogenesis discovered by non-invasive imaging modalities. Computed tomographic angiography was the preferred imaging modality for long-term follow-up of microsurgically clipped IAs. Magnetic resonance angiography (MRA) was the preferred modality for following IAs that were untreated, endovascularly-treated, or microsurgically-treated in a manner other than clipping. CONCLUSIONS We propose incidental untreated IAs to be followed by magnetic resonance angiography without contrast enhancement. Follow-up modality and interval for treated pediatric IAs is determined by initial aneurysmal complexity, treatment modality, and degree of posttreatment obliteration. Recurrence or de novo aneurysmogenesis requiring treatment should be followed by digital subtraction angiography and appropriate retreatment. Computed tomography angiography is preferred for clipped IAs, whereas contrast-enhanced magnetic resonance angiography is preferred for lesions treated endovascularly with coil embolization and lesions treated microsurgically in a manner other than clipping.

Internal Maxillary Bypass for Complex Pediatric Aneurysms. World Neurosurg 2017; 103:395-403. [PMID: 28433837 DOI: 10.1016/j.wneu.2017.04.055] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2017] [Revised: 04/06/2017] [Accepted: 04/07/2017] [Indexed: 11/20/2022]
Abstract
BACKGROUND Complex pediatric aneurysms (PAs) are an unusual clinicopathologic entity. Data regarding the use of a bypass procedure to treat complex PAs are limited. METHODS Internal maxillary artery-to-middle cerebral artery bypass with radial artery graft was used to isolate PAs. Bypass patency and aneurysm stability were evaluated using intraoperative Doppler ultrasound, indocyanine green videoangiography, and postoperative angiography. Modified Rankin Scale was used to assess neurologic function. RESULTS Over a 5-year period, 7 pediatric patients (≤18 years old) were included in our analysis. Mean age of patients was 14.4 years (range, 12-18 years), and mean size of PAs was 23.6 mm (range, 9-37 mm). All cases manifested with complex characteristics. Proximal artery occlusion was performed in 3 cases, complete excision following aneurysmal distal internal maxillary artery bypass was performed in 2 cases, and combined proximal artery occlusion and aneurysm excision was performed in the 2 remaining cases. Mean intraoperative blood flow was 61.6 mL/minute (range, 40.0-90.8 mL/minute). Graft patency rate was 100% during postoperative recovery and at the last follow-up examination (mean, 20 months; range, 7-45 months). All patients had excellent outcomes except for 1 patient who died of multiple-organ failure. CONCLUSIONS Internal maxillary artery bypass is an essential technique for treatment of selected cases of complex PAs.

Rapid de novo aneurysm formation after clipping of a ruptured middle cerebral artery aneurysm in an infant with an MYH11 mutation. J Neurosurg Pediatr 2016; 18:463-470.

Abstract
The authors report the case of a previously healthy 6-month-old girl who presented with right arm and leg stiffening consistent with seizure activity. An initial CT scan of the head demonstrated acute subarachnoid hemorrhage in the basal cisterns extending into the left sylvian fissure. Computed tomography angiography demonstrated a 7 × 6 × 5-mm saccular aneurysm of the inferior M2 division of the left middle cerebral artery. The patient underwent left craniotomy and microsurgical clip ligation with wrapping of the aneurysm neck because the vessel appeared circumferentially dysplastic in the region of the aneurysm. Postoperative angiography demonstrated a small remnant, sluggish distal flow, but no significant cerebral vasospasm. Fifty-five days after the initial aneurysm rupture, the patient presented again with an acute intraparenchymal hemorrhage of the left anterior temporal lobe. Angiogram revealed a circumferentially dysplastic superior division of the M2 branch, with a new 5 × 4-mm saccular aneurysm distinct from the first, with 2 smaller aneurysms distal to the new ruptured aneurysm. Endovascular parent vessel occlusion with Onyx was performed. Genetic testing revealed a mutation of the MYH11. To the authors' knowledge, this is the first report of rapid de novo aneurysm formation in an infant with an MYH11 mutation. The authors review the patient's clinical presentation and management and comprehensively review the literature on this topic.

Endovascular treatment of an adolescent patient with a ruptured intracranial aneurysm - case report and review of literature. Pol J Radiol 2015; 80:10-2. [PMID: 25574249 PMCID: PMC4284941 DOI: 10.12659/pjr.891344] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2014] [Accepted: 08/14/2014] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND The occurence of aneurysms in young patients, under 18 years of age, is estimated at 0.5-2% of all diagnosed aneurysms. CASE REPORT We reported on a case of a 16-year-old patient with subarachnoid hemorrhage diagnosed due to a ruptured cerebral vessel aneurysm. The angio-CT revealed an aneurysm of the middle cerebral artery, in its distal branch. An ad hoc coil embolization was performed with angiographic success. After 6 months following the ictus, the patient underwent a control angiography which confirmed total occlusion of the aneurysm with no residual inflow. Clinical examination revealed no neurological deficits and the patient was rated 0 in mRS (modified Rankin Scale). CONCLUSIONS In experienced departments of interventional neuroradiology the endovascular treatment should be the treatment of choice.

Abstract
Background and Purpose—
Long-term angiographic follow-up studies on pediatric aneurysm patients are scarce.
Methods—
We gathered long-term clinical and angiographic follow-up data on all pediatric aneurysm patients (≤18 years at diagnosis) treated at the Department of Neurosurgery, Helsinki University Central Hospital, between 1937 and 2009.
Results—
Fifty-nine patients with cerebral aneurysms in childhood had long-term clinical and radiological follow-up (median, 34 years; range, 4–56 years). Twenty-four patients (41%) were diagnosed with altogether 25 de novo and 11 recurrent aneurysms, with 9 (25%) of the aneurysms being symptomatic. New subarachnoid hemorrhage occurred in 7 patients; 4 of these patients died. Eight patients (33%) had multiple new aneurysms. The annual rate of hemorrhage was 0.4%, and the annual rate for the development of de novo or recurrent aneurysm was 1.9%. There were no de novo aneurysms in 7 patients with previously unruptured aneurysms. However, 1 recurrent aneurysm was diagnosed. Current and previous smoking (risk ratio, 2.44; 95% confidence interval, 1.07–5.55) was the only statistically significant risk factor for de novo and recurrent aneurysm formation in patients with previous subarachnoid hemorrhage, whereas hypertension, sex, or age at onset had no statistically significant effect. Smoking was also a statistically significant risk factor for new subarachnoid hemorrhage.
Conclusions—
Patients with ruptured intracranial aneurysms in childhood have a high risk for new aneurysms and new subarachnoid hemorrhage, especially if they start to smoke as adults. Life-long angiographic follow-up is mandatory.
