Definition of Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage as an Outcome Event in Clinical Trials and Observational Studies: Proposal of a Multidisciplinary Research Group
Background and Purpose— In clinical trials and observational studies there is considerable inconsistency in the use of definitions to describe delayed cerebral ischemia (DCI) after aneurysmal… Expand
Idiopathic intracranial hypertension
Objective: To determine the prevalence and nature of sinovenous obstruction in idiopathic intracranial hypertension (IIH) using auto-triggered elliptic-centric-ordered three-dimensional… Expand

PURPOSE To prospectively identify risk factors for neurologic complications related to cerebral angiography. MATERIALS AND METHODS A total of 2,899 consecutive cerebral digital subtraction… Expand
Arterial aneurysms associated with cerebral arteriovenous malformations: classification, incidence, and risk of hemorrhage.
OBJECT The goal of this study was to develop a classification system for aneurysms associated with arteriovenous malformations (AVMs) based on their anatomical and pathophysiological relationships… Expand
Clinical Course of Cranial Dural Arteriovenous Fistulas With Long-Term Persistent Cortical Venous Reflux
Background and Purpose— The natural history of aggressive (Borden 2 and 3) cranial dural arteriovenous fistulas (DAVFs) is not well described. Reported annual mortality and hemorrhage rates vary… Expand
Negative CT Angiography Findings in Patients with Spontaneous Subarachnoid Hemorrhage: When Is Digital Subtraction Angiography Still Needed?
BACKGROUND AND PURPOSE: CTA is becoming the frontline modality to reveal aneurysms in patients with SAH. However, in about 20% of SAH patients no aneurysm is found. In these cases, intra-arterial DSA… Expand
Intracranial arterial wall imaging using high-resolution 3-tesla contrast-enhanced MRI
Background: Conventional arterial imaging focuses on the vessel lumen but lacks specificity because different pathologies produce similar luminal defects. Wall imaging can characterize extracranial… Expand
Demographic, morphological, and clinical characteristics of 1289 patients with brain arteriovenous malformation.
BACKGROUND AND PURPOSE The purpose of this study was to assess demographic, clinical, and morphological characteristics of patients with brain arteriovenous malformations (AVMs). METHODS… Expand
The validity of classification for the clinical presentation of intracranial dural arteriovenous fistulas.

- Journal of neurosurgery
- 1 November 1996
A number of classification schemes for intracranial dural arteriovenous fistulas (AVFs) have been published that claim to predict which lesions will present in a benign or aggressive fashion based on… Expand
Multidisciplinary Management of Spinal Dural Arteriovenous Fistulas: Clinical Presentation and Long-Term Follow-Up in 49 Patients
Background and Purpose— In the early 1980s, it was demonstrated that surgical intradural division of the shunting vein to the medullary venous plexus cures a spinal dural arteriovenous fistula (DAVF)… Expand
