Su X, Ma Y, Song Z, Ye M, Zhang H, Zhang P. Paediatric intracranial dural arteriovenous fistulas: clinical characteristics, treatment outcomes and prognosis. Stroke Vasc Neurol 2024:svn-2024-003122. [PMID: 38839343 DOI: 10.1136/svn-2024-003122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Accepted: 05/09/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND Compared with dural arteriovenous fistulas (DAVFs) in adult, paediatric DAVFs are notable for distinct clinical manifestations, low cure rate and poor prognosis. However, due to the limitations of small sample sizes, the long-term prognosis and follow-up data have not been described. METHODS Clinical data from 43 consecutive paediatric DAVFs were documented and analysed between 2002 and 2022 at the author's institution. They were divided into infantile (Lasjaunias classification) and non-infantile (adult type and dural sinus malformation (DSM)) type DAVFs based on prognosis differences. RESULTS Their mean age at first symptoms was 8.4±6.0 years. 29 boys and 14 girls presented between at birth and 18 years of age. 5 of 10 patients ≤1 year of age presented with asymptomatic cardiomegaly compared with 5/33 patients >1 year of age (p=0.022). 42 (88.4%) patients received endovascular treatment alone, while 9.3% underwent radiosurgery, burr hole embolisation or surgery. 28 (65.1%) patients experienced DAVF obliteration by the end of treatment. Among them, 26 cases underwent embolisation alone, one case had embolisation in conjunction with surgery, and one case underwent burr hole embolisation. The overall complication rate among patients was 9.3%, all resulting from endovascular treatment. According to the Lasjaunias Classification, there were 18 cases of adult type, 17 cases of infantile type and 8 cases of DSM. Compared with non-infantile-type DAVFs, infantile-type DAVFs showed more times of treatment, lower cure rate and worse prognosis (p<0.001, 0.003 and 0.021, respectively). The average follow-up duration was 41.4±36.2 months (3-228 months). 8 (22.9%) patients died. CONCLUSIONS Most adult-type DAVFs and DSMs can now be effectively treated with embolisation, resulting in good outcomes and prognosis. However, there are still challenges in treating infantile-type DAVFs, and the prognosis is frequently poor.

Abstract
INTRODUCTION Brain arteriovenous malformations (bAVMs) present complex challenges in neurosurgery, requiring precise pre-surgical planning. In this context, 3D printing technology has emerged as a promising tool to aid in understanding bAVM morphology and enhance surgical outcomes, particularly in pediatric patients. This study aims to assess the feasibility and effectiveness of using 3D AVM models in pediatric bAVM surgery. METHODOLOGY The study was conducted at Great Ormond Street Hospital, and cases were selected sequentially between October 2021 and February 2023. Eight pediatric bAVM cases with 3D models were compared to eight cases treated before the introduction of 3D printing models. The 3D modelling fidelity and clinical outcomes were assessed and compared between the two cohorts. RESULTS The study demonstrated excellent fidelity between 3D models and actual operative anatomy, with a median difference of only 0.31 mm. There was no statistically significant difference in angiographic cure rates or complications between the 3D model group and the non-3D model group. Surgical time showed a non-significant increase in cases involving 3D models. Furthermore, the 3D model cohort included higher-grade bAVMs, indicating increased surgical confidence. CONCLUSION This study demonstrates the feasibility and efficacy of utilizing 3D AVM models in pediatric bAVM surgery. The high fidelity between the models and actual operative anatomy suggests that 3D modelling can enhance pre-surgical planning and intraoperative guidance without significantly increasing surgical times or complications. Further research with larger cohorts is warranted to confirm and refine the application of 3D modelling in clinical practice.

Abstract
Pediatric intracranial arteriovenous shunts are rare vascular malformations that can be diagnosed prenatally or postnatally, as an incidental finding or due to complications. We propose a review of cerebral vascular malformations in newborns and infants with special emphasis on neurosonography and Doppler ultrasound as the first diagnostic method. Sonography can thus contribute in the planning of further studies that are always necessary, and in post-therapy follow-up.

Abstract
OBJECTIVE Pial arteriovenous fistulas (PAVFs) are rare and mostly observed in children. However, the overall angioarchitecture, clinical features, treatments and long-term prognosis for pediatric patients remain unclear. METHODS Clinical data of consecutive 42 pediatric PAVFs were documented and analysed. According to the differences of age distribution and clinical features, they were split into a younger group (≤3 years old; 20 cases) and an older group (3-14 years old; 22 cases). RESULTS Their mean age was 4.9±3.9 years, and the mean preoperative modified Rankin Scale (mRS) score was 1.64±1.57. Fourteen patients (33.3%) were asymptomatic, followed by epilepsy (21.4%), intracranial haemorrhage (16.7%), hydrocephalus (9.5%), developmental delay (7.1%), intermittent headache (7.1%) and congestive heart failure (4.8%). Annual bleeding rate and rebleeding rate before treatment reached 3.86% and 3.17%. Poor venous drainage including sinus dynamic obstruction (21 cases, 50.0%) and sinus occlusion (17 cases, 40.48%) were found with high frequency among these patients. Finally, 33 cases were cured (78.57%), and 4 cases faced surgery-related complications (9.52%). During 24-140 months' follow-up, the mean mRS score reduced to 0.57±0.40. However, only 22 cases (52.38%) recovered to absolutely normal, and poor venous drainage was the risk factor for patients' incomplete recovery (p=0.028, Exp(B)=14.692, 95% CI 1.346 to 160.392). Compared with the older group, younger group showed more chronic symptoms, more secondary pathological changes, more times treatment and worse prognosis (p=0.013, 0.002, 0.000 and 0.032, respectively). CONCLUSIONS Pediatric PAVF has different angioarchitectures, clinical features and prognoses in different age groups. Poor venous drainage is an important factor leading to poor prognosis, and it accounts for incomplete recovery in nearly half of patients.

Abstract
BACKGROUND AND PURPOSE Intracranial arteriovenous shunts (IAVS) are rare vascular diseases in infants. They can be categorized into vein of Galen aneurysmal malformation (VGAM), pial arteriovenous fistula (PAVF), and dural arteriovenous fistula associated with dural sinus malformation (DAVF/DSM). We sought to review the clinical presentation, imaging characteristics, endovascular treatment (EVT), and outcomes of IAVS in infants presenting to a quaternary pediatric referral center over one decade. METHODS A retrospective review of a prospectively maintained database was performed of all infants diagnosed with IAVS between January 2011 and January 2021 in a quaternary pediatric referral center. For each patient, demographic data, clinical presentation, imaging findings, management strategies, and outcomes were reviewed and discussed. RESULTS Over the study period, 38 consecutive infants were diagnosed with IAVS. Patients with VGAM (23/38, 60.5%) presented with congenital heart failure (CHF) (14/23), hydrocephalus (4/23), and seizures (2/23), and three patients were asymptomatic. Eighteen patients with VGAM underwent EVT. Among those, 13 patients (72.2%) were successfully treated with an angiographic cure and three patients (3/18, 17%) died. Patients with PAVF (9/38, 23.7%) presented with CHF (5/9), intracranial hemorrhage (2/9), and seizures (2/9), and all of them were successfully treated endovascularly. Patients with Type I DAVF/DSM (4/6, 66.6%) presented with mass effect (2/4), cerebral venous hypertension (1/4), CHF (1/4), and cerebrofacial venous metameric syndrome (1/4). Patients with type II DAVF/DSM (2/6, 33.3%) presented with a thrill behind the ear. Patients with DAVF/DSM were treated endovascularly, five patients were cured, and one with type I DAVF/DSM died. CONCLUSION Intracranial arteriovenous shunts are rare but potentially life-threatening neurovascular pathologies in infants. Endovascular treatment is challenging but feasible in carefully selected patients.

Abstract
Pediatric neurovascular disorders can lead to substantial mortality and morbidity if not diagnosed early and adequately managed. Children with neurovascular diseases cannot be treated as small adults as the vascular and central nervous system anatomy, physiology, and pathologies in children differ greatly from those of adults. In addition, some neurovascular pathologies are seen exclusively in children such as aneurysmal malformation of the vein of Galen, pial fistulas, and dural fistulas in the context of dural sinus disease. In this review, we aim to present an overview of the common pediatric neurovascular diseases along with their endovascular management.

Abstract
Pediatric interventional neuroradiology (PINR) is a relatively new field of diagnostic and therapeutic care in the pediatric population that has seen considerable advances in recent decades. However, it is still lagging behind adult interventional neuroradiology due to a variety of reasons, including the lack of evidence validating pediatric-specific procedures, the relative absence of pediatric-specific equipment, and the challenges in establishing and maintaining PINR competencies in a relatively small number of cases. Despite these challenges, the number and variety of PINR procedures are expanding for a variety of indications, including unique pediatric conditions, and are associated with reduced morbidity and psychological stigma. Continued technological advances, such as improved catheter and microwire designs and novel embolic agents, are also contributing to the growth of the field. This review aims to increase awareness of PINR and provide an overview of the current evidence base for minimally invasive neurological interventions in children. Important considerations, such as sedation, contrast agent use, and radiation protection, will also be discussed, taking into account the distinct characteristics of the pediatric population. The review highlights the usefulness and benefits of PINR and emphasizes the need for ongoing research and development to further advance this field.

Abstract
INTRODUCTION Dural sinus malformation is a rare congenital malformation characterized by a remarkable dilated dural sinus pouch. We described the development of bilateral subdural hematoma after endovascular embolization of a dural sinus malformation in an infant. CASE DESCRIPTION A 32-day male infant was observed to have a fever and enlarged head circumference. A dural sinus malformation with giant dural sinus pouch thrombosis was established by magnetic resonance imaging and digital subtraction angiography. The patient developed bilateral subdural hematoma after endovascular embolization of the dural fistula. His neurological outcome was normal at 3-year follow-up. CONCLUSION We report a case of development of bilateral subdural hematoma after endovascular embolization of a dural sinus malformation and had a normal neurological outcome.

Abstract
The management of newborns with vein of Galen aneurysmal malformation (VGAM) is clinically challenging for neonatologists and cardiologists. Hemodynamic profiles in four fetuses diagnosed with VGAM who subsequently developed neonatal cardiac failure and pulmonary hypertension were studied using two-dimensional and Doppler echocardiography. All four had an increased cardiothoracic ratio due to right ventricular dilatation on antenatal ultrasound. Doppler studies of the aortic isthmus were abnormal with retrograde flow starting in mid systole and throughout diastole. Left and right ventricular outputs were significantly increased. Net pulmonary flow was highly abnormal with a flow rate almost four times higher than normal. After a short period of clinical stability, all neonates developed cardiac failure and pulmonary hypertension. This article reviews VGAM pathophysiology and the potential relationship between pulmonary hypertension and VGAM, supporting early post-natal treatment of pulmonary hypertension and right ventricular failure.

Abstract
The vein of Galen aneurysmal malformation (VGAM) is a rare cerebral arteriovenous malformation that can be life-threatening if not diagnosed and treated early. VGAM usually presents in the neonatal period with high-output cardiac failure. We report the case of a full-term male neonate who presented with respiratory distress, and a fontanel bruit soon after birth. A chest radiograph revealed marked cardiomegaly. Transthoracic echocardiography showed dilatation of all four cardiac chambers and a patent ductus arteriosus. Transfontanellar doppler ultrasound and brain computed tomography confirmed the diagnosis of a VGAM. Clinical worsening took place despite aggressive hemodynamic and ventilatory support. The patient's Bicêtre Neonatal Evaluation Score for embolization was 2. Endovascular treatment could not be performed. The patient regretfully passed away. VGAM should be considered in the differential diagnosis of neonatal congestive heart failure with a structurally normal heart. Early diagnosis and treatment improve prognosis considerably.

Abstract
BACKGROUND Vein of Galen malformation (VGM) is a rare congenital intracerebral vascular malformation. The aim of this study was to gain reliable data about epidemiology; clinical manifestations; and pre-, peri- and postinterventional treatment strategies in Germany. METHODS This prospective epidemiologic study was conducted by Erhebungseinheit für Seltene Pädiatrische Erkrankungen in Deutschland, a hospital-based German nationwide surveillance unit for rare pediatric diseases. Patients aged upto 18 years with a new diagnosis of VGM were prospectively included between January 1, 2014 and December 31, 2015. RESULTS In the two-year study period, 30 individuals with newly diagnosed VGM were identified, resulting in an estimated annual incidence rate of VGM in Germany of at least 1: 58,100 live births. The main symptoms were age dependent. Neonates presented with mainly cardiac manifestations of high output failure; infants and older children mainly suffered from neurological complications. Of the patients with endovascular treatment 95% survived, but only 41% of these patients were discharged home without any complications. The Bicêtre Neonatal Evaluation Score was a good predictor for poor outcome but could have led to palliative care in some patients with good outcome. CONCLUSIONS The incidence of VGM in Germany is estimated to be 1:58,100 live births. The majority of patients were eligible for endovascular treatment. Nevertheless, due to side effects and long-term sequelae in the majority of patients, further improvement in care of children with VGM is needed.

Abstract
OBJECTIVE Cerebral pial arteriovenous fistula (AVF) is a rare vascular malformation and may cause hemorrhage and neurological deficit. The presence of high-flow shunts constitutes a challenge when performing the endovascular technique, due to risk of distal embolization. The authors report a simple maneuver, adapted from the Matas test, that was successfully applied to treat a child with two pial AVFs. METHODS An 8-year-old boy presented with headache and vomiting due to two single-channel high-flow intracerebral pial AVFs. He was treated with an endovascular approach using brief, gentle compression of the ipsilateral cervical carotid artery. The temporary flow arrest ensured proper placement of the first coil, allowing definitive obliteration of the shunt. RESULTS There were no complications with the procedure, and the patient recovered uneventfully. Throughout the 9-month follow-up, the patient experienced a stable neurological condition, with both fistulas occluded and improvement of local circulation. CONCLUSIONS This easy-to-perform maneuver allows precise positioning of embolic material into high-flow shunts to facilitate treatment of pial AVF.

Abstract
Paediatric intracranial vascular malformations are rare and different from adult ones in vascular anatomy, pathophysiology, and symptoms. Their impact on the brain and their symptoms will differ in the antenatal period, in neonates, infants, and children. Clinical presentation includes seizures, focal neurological deficit, haemorrhage, congestive heart failure, hydrovenous disorder, and developmental delays. These malformations are thus associated with a poor prognosis if left untreated. Therefore, aggressive management is generally recommended and must be performed by a multidisciplinary team with extensive experience. Endovascular treatment is the first-choice treatment for most paediatric intracranial vascular malformations. Indication and timing for treatment should be decided on the basis of a careful assessment of neurological symptoms, growth and development, cardiac and other systemic manifestations, and imaging of the malformation and the brain tissue. WHAT THIS PAPER ADDS: Paediatric intracranial vascular malformations are rare, but their prognosis is poor if left untreated. Improved clinical, anatomical, and pathophysiological understanding of these complex lesions has improved prognosis.

Abstract
BACKGROUND Vein of Galen aneurysmal malformations (VOGMs) are pial arteriovenous fistulas possessing Galenic venous drainage most commonly presenting during the neonatal period and infancy, with initial discovery during adulthood quite rare. OBJECTIVES AND METHODS We conducted a literature survey of the PubMed database in order to identify Galenic pial arteriovenous fistulas (GPAVFs) with major manifestation or initial presentation during adulthood. Inclusionary criteria included pial AVFs with Galenic drainage with major manifestation or initial presentation at, or older than, 18 years. Exclusionary criteria included exclusive pediatric onset of symptomatology attributable to GPAVFs without a new onset major presentation during adulthood, exclusive or major dural arterial supply, arteriovenous malformations with Galenic drainage, developmental venous anomalies with Galenic drainage, isolated varices or anomalies of the vein of Galen, and any lesions with uncertainty regarding true GPAVF nature. RESULTS Our search generated 1589 articles. Excluding duplicates, 26 cases met criteria for evaluation. Mean age was 34.1 +/- 2.53 years. Clinical presentations of GPAVFs among adults included headache, intracranial hemorrhage, seizures, and focal neurologic deficits. Management strategies included observation (n = 5), emergent ventriculostomy or Torkildsen shunt (n = 3), cerebrospinal fluid diversion via ventriculoperitoneal shunting (n = 4), microsurgical obliteration or thrombectomy (n = 4), transarterial and/or transvenous embolotherapeutic obliteration (n = 7), and concurrent embolotherapy and radiosurgical irradiation (n = 1). CONCLUSIONS GPAVFs in adults often present with symptomatology of mild severity and may be effectively managed conservatively, though occasionally present catastrophically or may be treated via cerebrospinal fluid diversion, microsurgical obliteration, or endovascular embolization. Severity sufficient to require emergent intervention portended a poor outcome.
