Abstract
BACKGROUND AND PURPOSE Cervical artery dissection (CAD) involving the carotid or vertebral arteries is an important cause of stroke in younger patients. The purpose of this systematic review is to assess the risk of recurrent CAD. METHODS A systematic review and meta-analysis was conducted on studies in which patients experienced radiographically confirmed dissections involving an extracranial segment of the carotid or vertebral artery and in whom CAD recurrence rates were reported. RESULTS Data were extracted from 29 eligible studies (n = 5898 patients). Analysis of outcomes was performed by pooling incidence rates with random effects models weighting by inverse of variance. The incidence of recurrent CAD was 4% overall (95% confidence interval (CI) = 3-7%), 2% at 1 month (95% CI = 1-5%), and 7% at 1 year in studies with sufficient follow-up (95% CI = 4-13%). The incidence of recurrence associated with ischemic events was 2% (95% CI = 1-3%). CONCLUSIONS We found low rates of recurrent CAD and even lower rates of recurrence associated with ischemia. Further patient-level data and clinical subgroup analyses would improve the ability to provide patient-level risk stratification.

Abstract
Vertebral artery dissection (VAD) is a common cause of a rare condition, pediatric posterior circulation arterial ischemic stroke (PCAIS). VAD is clinically important due to the risk of multifocal and continuing infarcts from artery-to-artery thromboembolism, with the potential for occlusion of arteries that perfuse the brainstem. Early diagnosis is important, as recurrent stroke is a common effect of VAD in children. Although the relative efficacies of different treatment regimens for VAD in children remain unsettled, early initiation of treatment can mitigate the risk of delayed stroke. Clinical diagnosis of PCAIS may be delayed due to multiple factors, including nonspecific symptoms and the inability of younger patients to express symptoms. In fact, subacute or chronic infarcts are often present at initial imaging. Although the most common cause of isolated PCAIS is VAD, imaging of the cervical arteries has been historically underused in this setting. Cervical vascular imaging (MR angiography, CT angiography, and digital subtraction angiography) for VAD must be optimized to detect the sometimes subtle findings, which may be identified at initial or follow-up imaging. Osseous variants of the craniocervical junction and upper cervical spine and other extrinsic lesions that may directly injure the vertebral arteries or lead to altered biomechanics have been implicated in some cases. The authors review characteristic imaging features and optimized imaging of VAD and associated PCAIS and related clinical considerations. Identification of VAD has important implications for evaluation, treatment, and imaging follow-up, as this condition may result in progressive arteriopathy and recurrent stroke. © RSNA, 2023 Supplemental material is available for this article.

Abstract
The course of the vertebral artery from its subclavian artery origin up to its termination at the vertebrobasilar junction is divided into four segments (V1-V4). This segmentation, based on schemes that have evolved since the late nineteenth century, should be a consistent and reproducible anatomical concept. However, the current literature offers conflicting definitions of that scheme, not infrequently within a single article or monograph. The principal inconsistency found in modern publications concerns the termination of the V2 segment, which is either set at the C2 or C1 transverse foramen depending on the scheme considered. Consequently, the portion of the vertebral artery extending between C2 and C1-a frequent site of pathological involvement-either belongs to the V2 or V3 segment. This discrepancy can affect the validity of studies evaluating the diagnosis and management of vertebral artery disorders. A V3 segment extending from the transverse foramen of C2 to the posterior atlanto-occipital membrane and subdivided into vertical, horizontal, and oblique subsegments-a pattern suggested by Barbieri in 1867 and adopted in some modern publications-would provide a simple, precise, and reliable solution without significantly altering the widely accepted division of the vertebral artery into four segments (V1-V4).

Neurological vertigo in the emergency room in pediatric and adult age: systematic literature review and proposal for a diagnostic algorithm. Ital J Pediatr 2022; 48:125.

Abstract
Neurological vertigo is a common symptom in children and adults presenting to the emergency department (ED) and its evaluation may be challenging, requiring often the intervention of different medical specialties. When vertigo is associated with other specific symptoms or signs, a differential diagnosis may be easier. Conversely, if the patient exhibits isolated vertigo, the diagnostic approach becomes complex and only through a detailed history, a complete physical examination and specific tests the clinician can reach the correct diagnosis. Approach to vertigo in ED is considerably different in children and adults due to the differences in incidence and prevalence of the various causes. The aim of this systematic review is to describe the etiopathologies of neurological vertigo in childhood and adulthood, highlighting the characteristics and the investigations that may lead clinicians to a proper diagnosis. Finally, this review aims to develop an algorithm that could represent a valid diagnostic support for emergency physicians in approaching patients with isolated vertigo, both in pediatric and adult age.

Abstract
Posterior circulation acute ischaemic stroke in childhood is a rare but life-threatening disease. We describe a paediatric case of a 17-year-old Indian boy who was admitted to our centre for headache, nausea, vomiting, asthenia, and fever for two days. Computed tomography angiography (CTA), magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) were performed, showing a thrombotic occlusion of the basilar artery due to focal dissection into the proximal third of the left vertebral artery. In a multidisciplinary fashion, we decided to perform a direct aspiration first pass technique (ADAPT), which led to the complete recanalization of either the left vertebral artery or the basilar artery. Twenty-four hours later, despite the anti-edemigenic medical therapy, a preventive occipital craniectomy was performed because of the presence of cerebral oedema to avoid the possible worsening of the patient and compression on the brainstem. Our experience emphasizes the importance of a multidisciplinary and preventive approach in the management of a paediatric posterior fossa ischaemic stroke.

Abstract
Background and Purpose: Neurofibromatosis Type 2 (NF2) is an autosomal-dominant tumor-prone disorder characterized by the manifestations of central nervous system lesions. However, the first clinical signs of disease are often non-tumorous. Cerebrovascular insults are known in NF2, however, not yet described as first symptom in young NF2 patients. Methods: Magnetic resonance image scans of 298 NF2 patients treated in our neurofibromatosis center in Tübingen from 2003 to 2017 were retrospectively evaluated focusing on presence of aneurysms and ischemic stroke. Clinical data were used to clarify whether or not ischemic stroke or aneurysm rupture were the first presentation of disease. Blood of the patients were subjected to genetic screening for constitutional NF2 mutations. Results: We identified 5 cases under age of 25 years with aneurysms or ischemic stroke. Among them three had ischemic strokes of the brain stem and one aneurysmal subarachnoid hemorrhage as the first symptom of the disease. Incidental finding of 2 intracranial aneurysm occurred in one patient. All aneurysms were clipped. Patients with ischemia suffered from dysarthria, gait disturbances, dizziness, and hemiparesis. Residual signs of hemiparesis and dysarthria persisted in one patient. All others fully recovered from the cerebrovascular insult. Bilateral vestibular schwannomas and intracranial meningiomas were found in all five patients. Conclusions: A cerebrovascular insult in the vertebrobasilar territory may occur as first symptom of disease in young NF2 patients. The brain stem seems to be especially prone to ischemic stroke. Multicenter studies on large NF2 cohorts are needed to determine the prevalence and pattern of cerebrovascular insults and disease in NF2 patients.

Abstract
OBJECTIVE Educate providers about the clinical presentation and consequences of delaying diagnosis of traumatic vertebral artery dissection with thromboembolic ischemic strokes in the pediatric population. Vertebral artery dissection is often difficult to diagnose and can be a potentially devastating cause of ischemic stroke. METHODS Review of the chart, peer review/discussion, and imaging interpretation. RESULTS A 16-year-old boy was admitted with confusion after a head and neck trauma was sustained while wrestling. (Glasgow Coma Scale=15, NIHSS = 0). Investigations including computed tomography (CT) head and cervical spine were normal. He then developed severe nausea, vomiting, dizziness, and headaches and was admitted for symptoms of concussion. Ten hours later, patient declined (hypertensive and unresponsive) and was noted to have decerebrate posturing. After emergent intubation, he was transferred to the pediatric intensive care unit. Repeat CT head showed an acute left cerebellar infarct with associated cerebellar edema resulting in effacement of the fourth ventricle/basilar cisterns and acute hydrocephalus. The CT angiography and magnetic resonance imaging of brain confirmed arterial dissection and near occlusion of the left vertebral artery at the C2 level. Extensive infarct was seen in the left cerebellum, brainstem, and right cerebellum. During a prolonged hospital stay, the family opted to continue care, and he was transferred to an inpatient rehabilitation facility because of limited brainstem activity, being nonverbal, and not demonstrating purposeful spontaneous movements. CONCLUSIONS Detailed history and thorough neurological examination in conjunction with appropriate imaging are necessary to distinguish between brainstem/cerebellar ischemia from vertebral artery dissection and concussion.
