Hongzhi Xu, Zhiyong Qin, Ming Xu, Chunjui Chen, Junjie Zhang, Xiancheng Chen
BACKGROUND: Intraoperative ultrasound is widely used in neurosurgery for the management of intracerebral hematoma and brain tumor. However, the clinical value of this method in the surgery of cerebral arteriovenous malformations (AVMs) has not been reported. In this study, the application of intraoperative ultrasound for AVMs surgery was evaluated prospectively. METHODS: This prospective clinical study comprised of 41 patients who underwent microsurgical resection of cerebral AVMs at our institute...

INTRODUCTION: Embolisation has long been used as an adjunct to surgical resection in the treatment of brain arteriovenous malformation (bAVM). The most commonly used embolic material, n-butylcyanoacrylate glue, requires experience and skill to handle its quick and unpredictable flow and polymerisation. A new liquid embolic agent, ethylene vinyl alcohol copolymer (Onyx), is less adhesive and polymerises slowly, which provides better control for radiologists performing embolisation. OBJECTIVE: To report our experience in embolisation using Onyx alone or in combination with histoacryl for bAVM embolisation in our tertiary referral centre...

BACKGROUND: Aneurysms associated with brain arteriovenous malformations (bAVMs) influence the natural history of these lesions and pose important therapeutic challenges. However, the epidemiology, natural history, and appropriate management of the aneurysms associated with bAVMs are not completely understood due to the paucity of large and uniform studies. We performed a systematic review of published series examining the association between aneurysms and bAVMs with the purpose of clarifying the prevalence, risk of hemorrhage, and appropriate management of these lesions...

Seizures are common symptoms of supratentorial arteriovenous malformations (AVMs). The potential risk factors for epilepsy in patients with AVMs are still controversial. The reported long-term outcome of seizures after surgical treatment of AVMs is variable and the data available are mainly from small retrospective case series.We identified all consecutive patients between 1990 and 2006 who underwent microsurgical resection of supratentorial AVMs at our institute. Pre-operative risk factors for seizures, intra-operative characteristics, long-term neurological disability, and seizure outcome (Engel's classification) were recorded and analyzed...

OBJECTIVE Brain arteriovenous malformations (AVMs) can occur in patients with hereditary hemorrhagic telangiectasia (HHT). However, brain AVM without HHT has also been reported. Using whole exome sequencing, the authors performed comprehensive genomic characterization of a 6-person Turkish family with 3 cases of brain AVM without HHT. METHODS Three siblings with brain AVM, one of whom also had spinal AVM, were evaluated. The parents and the fourth sibling had no AVM on cranial MRI. The authors performed a whole exome capture and Illumina sequencing on blood samples from 2 siblings with AVM...

Intracranial arteriovenous shunts (ICAVSs) in young children are characterized with frequent high flow fistulas. In association of high flow fistulas and physiological condition of the developing brain and heart, each disease tends to present at a certain age with unique symptoms. Vein of Galen aneurysmal malformation (VGAM) and dural sinus malformation (DSM) with arteriovenous (AV) shunts tend to present in neonate with high output cardiac failure. In infancy, VGAM, pial AVF and infantile dural AVF tend to present with hydrodynamic disorder such as macrocephaly, ventriculomegaly, prominent facial veins, and developmental delay...

BACKGROUND: Intracranial vascular malformations in children are being addressed through a variety of treatment modalities including open surgery, external beam radiation, and image-guided neuroendovascular procedures. These patients often receive multiple treatments and incur serial exposures to ionizing radiation which has been linked to tumor development in population-based data. OBJECTIVE: This study quantifies the effect of collimation on exposures from single procedures and over patient lifetimes to estimate excess risk of lifetime tumor development...

OBJECTIVE The occurrence of transdural arterial recruitment (TDAR) in association with brain arteriovenous malformation (bAVM) is uncommon, and the reason for TDAR is not understood. The aim of this cohort study was to examine patient and bAVM characteristics associated with TDAR and the implications of TDAR on management. METHODS A prospective surgical database of bAVMs was examined. Cases previously treated elsewhere or incompletely examined by digital subtraction angiography (DSA) assessment were excluded...

Brain edema due to venous thrombosis following stereotactic radiosurgery for a cerebral arteriovenous malformation (AVM) has rarely been reported. We report a patient with a large AVM in the eloquent area, and brain edema developed in this area after repeat Gamma knife stereotactic radiosurgery (GKRS). An 18-year-old female presented with a 4-year-history of persistent headache. Magnetic resonance imaging and transfemoral carotid angiogram revealed a high-flow large AVM in the left parieto-occipital area. Brain edema developed and aggravated patient's symptoms after time-staged GKRS...

INTRODUCTION: Glioblastoma can mimic various pathologies, including arteriovenous malformation, hemorrhage from ischemic stroke, cerebral contusion, metastatic disease, lymphoma, and infection. The literature is limited regarding diagnostic confusion with meningioma. Herein, we present two patients that exhibited imaging, including cerebral angiography during preoperative embolization, which was consistent with meningioma, but where final surgical diagnosis revealed glioblastoma. CASE 1: A 57-year-old female presented with headaches, ataxia, and memory lapses for the past month...

Cerebral proliferative angiopathy (CPA), which is characterized by diffuse vascular abnormalities with intermingled normal brain parenchyma, is a rare clinical entity distinct from classical cerebral arteriovenous malformations. Its pathology at initial state and subsequent course of progression has totally been undetermined. We herein presented a case of a child who was initially diagnosed with deep-seated arteriovenous fistula (AVF), and ultimately developed symptomatic CPA-like vascular lesion over a long period of clinical follow-up...

OBJECTIVE Brain arteriovenous malformations (bAVMs) are rare in pediatric patients but represent the most common cause of hemorrhagic stroke in this population. Pediatric patients demonstrate superior outcomes in comparison with adult patients with similar lesions and presentations. Most studies of clinical outcomes of pediatric bAVMs use the modified Rankin Scale (mRS), despite a lack of validation in pediatric patients. METHODS The authors interviewed the parents of 26 pediatric patients who underwent multimodality bAVM treatment and administered the Pediatric Quality of Life Inventory (PedsQL)-a well-validated tool for pediatric outcomes that quantifies performance in a physical, emotional, social, and school domains...
