The purpose of this article is to review and update the current status of carotid artery stent placement in the world. Surveys to major interventional centers in Europe, North and South America, and Asia were initially completed in June 1997. Subsequent information from these 24 centers in addition to 12 new centers has been obtained to update the(More)
Seven patients with intracavernous aneurysms were treated by proximal balloon occlusion of the carotid artery, with no attempt to preserve carotid blood flow. After a 15-minute occlusion trial, two balloons were detached proximal to the neck of these aneurysms. Major clinical improvement occurred in six patients and no procedure-related complications were(More)
PURPOSE To assess effectiveness of endovascular treatment of carotid artery stenosis by means of angioplasty with cerebral protection and stent placement. MATERIALS AND METHODS Angioplasty was performed for carotid artery stenosis in 259 patients. Cerebral protection (triple coaxial catheter) was used in 136 cases of atherosclerotic stenosis in the(More)
Our purpose was to review the current status of carotid artery stent placement throughout the world. Surveys were sent to major interventional centers in Europe, North and South America, and Asia. Information from peer-reviewed journals was also included and supplemented the survey. The survey asked various questions regarding the patients enrolled,(More)
Treatment of gliomas remains disappointing in spite of a great number of experimental biological data and of randomized therapeutic studies. This could be partly explained by the inefficiency of our conventional methods to assess the regional metabolism of these tumors. The use of positron emission tomography (PET) brings encouraging possibilities in this(More)
A series comprising 12 patients who had intraarterial local fibrinolysis in the carotid territory is reported. A classification is proposed that divides the different types of occlusions into three groups on the basis of angiographic location. Group 1 (two cases) comprises occlusion of the extra- and/or intracranial carotid artery with patency of the circle(More)
A technique for safe angioplasty of atherosclerotic stenosis of internal and common carotid arteries is described in which temporary balloon occlusion of the internal carotid artery is used to prevent cerebral embolization during manifestation of ulcerated plaques. Its successful use in six atherosclerotic stenosis is described. Five angioplasties of(More)
Many studies of white matter high signal (WMHS) on T2-weighted MRI have disclosed that it is related to cerebral ischaemia and to brain atrophy. Atrophy of the corpus callosum (CC) has also been studied in relation to ischaemia. Our objective was to test the hypothesis that CC atrophy could be due to ischaemia. We therefore assessed CC, WMHS and brain(More)
