BACKGROUND Intracranial hemorrhage is the most dreaded risk of thrombolytic therapy for acute myocardial infarction because of the high mortality and disability rates associated with this complication. Brain structural lesions may predispose a patient to bleeding. To date, aneurysm rupture has not been described as a complication of such therapy. CASE(More)
BACKGROUND AND OBJECTIVE Factors related to prognosis after subarachnoid haemorrhage (SAH) have been mainly extracted from surgical series, and only few authors have considered these factors in total management or population series. Though the level of consciousness is a major determinant of outcome after subarachnoid haemorrhage, there is not a consensus(More)
OBJECTIVE In the past, several possible explanations for idiopathic subarachnoid hemorrhage (ISAH) have been proposed; however, neuroimaging studies have never provided conclusive data about the structural cause of the bleeding. The aim of this study is to determine whether there are anatomic differences in the deep cerebral venous drainage in patients with(More)
BACKGROUND AND PURPOSE Although digital subtraction angiography (DSA) is the reference standard for assessing carotid arteries, it is uncomfortable for patients and has a small risk of disabling stroke and death. These problems have fueled the use of spiral CT angiography and MR angiography. We prospectively compared elliptic centric contrast-enhanced MR(More)
OBJECT Microarteriovenous malformations (micro-AVMs) are a rare subgroup of brain AVMs characterized by a nidus smaller than 1 cm. The authors' purpose in this study was to assess the clinical presentation, radiological features, therapeutic management, and outcome of these lesions. METHODS All angiography studies performed at the authors' institution(More)
BACKGROUND Most scales used to assess prognosis after subarachnoid haemorrhage (SAH) are based on the level of consciousness of the patient. Based on information from a logistic regression model, Ogilvy et al. developed a new grading scheme (Massachussetts General Hospital (MGH) Scale) which applied a simple scoring method to each prognostic factor(More)
SUMMARY We report fusiform aneurysms in both internal carotid arteries in a 74-year-old man who presented with a nonpulsatile retropharyngeal mass. Both helical CT and MR imaging disclosed the nature of the lesions. Arteriography, required for therapeutic decisions, confirmed the diagnosis. Because of the rarity of this condition and the potential for(More)
OBJECTIVES To analyse the clinical, radiological and therapeutic variables of intracranial dural arteriovenous fistulae (DAVF) treated at our institution, and to assess the validity of the Borden and Cognard classifications and their correlation with the presenting symptoms. MATERIAL AND METHODS The DAVF identified were retrospectively analysed. They were(More)
UNLABELLED OBJECTIVES AND INTRODUCTION: The pathogenesis and natural history of intracranial vertebral artery dissection remain uncertain up to now due in part to its relative rarity. In this article we review the state of the art of this process and remark the good outcome obtained with embolization using Guglielmi detachable coiling (GDC). METHODS Two(More)
