Brain arteriovenous malformations (AVMs) are abnormal vascular connections within the brain that are presumably congenital in nature. There are several subgroups, the most common being glomerular type brain AVMs, with fistulous type AVMs being less common. A brain AVM may also be a part of more extensive disease (eg, cerebrofacial arteriovenous metameric(More)
OBJECTIVE To determine the course of vascular changes in childhood post-varicella arteriopathy (PVA) and its relationship to recurrent arterial ischemic stroke or TIA (AIS/TIA). METHODS Subjects were children with AIS/TIA occurring <1 year after varicella, ischemic localization consistent with unilateral disease affecting the supraclinoid internal carotid(More)
Current diagnosis and surgical correction of craniofacial anomalies would benefit from accurate quantitative and standardized points of reference. A retrospective study was undertaken to define normal values for a series of craniofacial measurements and to evaluate the growth patterns of the craniofacial complex through axial computed tomography (CT).(More)
Seventy-two children with posterior fossa medulloblastoma were diagnosed at the Hospital for Sick Children, Toronto, from 1977 to 1987 and treated by standard methods. The 5- and 10-year survival and disease-free survival rates were 71% and 63%, and 64% and 63%, respectively. Total tumor resection, as determined by the surgeon was the most significant(More)
BACKGROUND There is no treatment protocol or standardised documentation of neurological outcome for patients with small vessel childhood primary angiitis of the CNS, a rare inflammatory brain disease. We aimed to assess a treatment regimen and describe long-term neurological outcomes in a cohort of children with this disorder. METHODS We did a(More)
PURPOSE To compare the clinical results of percutaneous sclerotherapy of venous vascular malformations (VVMs) with the authors' proposed magnetic resonance (MR) imaging classification. MATERIALS AND METHODS MR findings and clinical results of percutaneous alcohol sclerotherapy in 59 pediatric patients with VVMs were retrospectively reviewed. Before(More)
We reviewed our experience with nine consecutive patients with untreated isolated nonsyndromic sagittal synostosis. Using a method of 14 clinically relevant measurements taken from preoperative and postoperative CT scan images of these patients, we documented their presenting skeletal dysmorphology and the results of surgical correction at least 1 year(More)
OBJECT Approximately 30% of children with posterior fossa tumors exhibit hydrocephalus after tumor resection. Recent literature has suggested that prophylactic endoscopic third ventriculostomy diminishes the risk of this event. Because the majority of patients will not have postoperative hydrocephalus, a preoperative clinical prediction rule that identifies(More)
OBJECTIVES To review all cases of pediatric aneurysms, we treated and evaluated their characteristics. The objective of the study is to compare between surgical and endovascular approaches regarding treatment and outcome. METHODS All cases of pediatric intracranial aneurysms diagnosed and managed by our team in the last 12 years were prospectively(More)
