The in vivo quantification of the benzodiazepine receptor concentration in human brain using positron emission tomography (PET) and 11C-flumazenil (11C-FMZ), is usually based on a three-compartment model and on PET curves measured in a small number of large regions of interest; however, it should be interesting to estimate the receptor concentration for(More)
BACKGROUND AND PURPOSE Although stent-assisted intracranial procedures are becoming a routine clinical practice, there have been relatively few large studies published in the literature regarding the application of the balloon-expandable stent technology in the treatment of intracranial arterial diseases. In this report, the authors reviewed their(More)
BACKGROUND AND PURPOSE Ischemic stroke is the most common complication after surgical clipping of anterior choroidal artery (AChA) aneurysms, and the reported morbidity-mortality rates vary from 5% to 50%. We report the findings in a series of 18 consecutive patients who underwent endovascular treatment (EVT) for an AChA berry aneurysm. METHODS In this(More)
Somesthetic and emotional symptoms that are common in patients with mesial temporal lobe epilepsy are usually related to hippocampo-amygdalar complex involvement. Recent stereo-electroencephalographic studies have shown a relationship between such symptoms and epileptic insular discharges. To further investigate this problem, we carried out a positron(More)
BACKGROUND AND PURPOSE To report our experience in the treatment of brain arteriovenous malformations (BAVMs) using Onyx (ev3, Irvine, Calif). PATIENTS AND METHODS From January 1999 to October 2004, 94 patients with BAVMs were treated endovascularly in our department. They were 51 (54%) men and 43 (46%) women with a mean age of 32 years. A total of 210(More)
We reviewed the cranial MRI and radionuclide cisternograms of four adults with postural headache indicating spontaneous intracranial hypotension (SIH). All four underwent clinical and radiological follow-up. MRI showed diffuse, thin meningeal enhancement; bilateral subdural fluid collections; and morphological abnormalities secondary to "sagging" of the(More)
A 71-year-old female patient presented with a wide-necked carotid cavernous aneurysm for which stent and coil placement was planned. Arterial tortuosity required direct puncture of the common carotid artery for access. The procedure was performed while the patient was receiving antiplatelet and anticoagulative therapy. To avoid potentially hazardous and(More)
BACKGROUND AND PURPOSE A precise analysis of the immediate postoperative anatomic results in a large series of unruptured intracranial aneurysms treated by endovascular approach has not previously been presented. This study aimed to assess the efficacy of endovascular treatment of unruptured intracranial aneurysms in light of immediate postoperative(More)
The balloon remodeling technique was initially designed for the endovascular treatment of anatomically complex aneurysms, specifically wide-neck aneurysms. A nondetachable balloon is inflated in front of the aneurysm neck during coil deposition and removed at the end of the procedure. Some controversies regarding the safety of the technique were introduced(More)
INTRODUCTION Morphology of the Silk stent (Balt, Montmorency, France) after deployment is not fully understood, especially in tortuous vessels. An in vitro study was conducted to study morphology and flow-diverting parameters of this stent. METHODS Two sets of different-sized and curved polytetrafluoroethylene tubes were studied. To simulate the aneurysm(More)
