BACKGROUND AND PURPOSE Stent-assisted coiling has expanded the treatment of intracranial aneurysms, but the rates of procedure-related neurological complications and the incidence of angiographic aneurysm recurrence of this novel treatment are not yet well known. We present our experience with stent-assisted coiling with special emphasis on(More)
PURPOSE To evaluate the stability of aneurysm occlusion at follow-up angiography after endovascular treatment (EVT) with detachable coils in intracranial berry aneurysms. MATERIALS AND METHODS A total of 203 berry aneurysms (< 1.5 cm) were treated with EVT. Follow-up angiography at least 3 months later was performed in 169 cases. RESULTS Complete(More)
BACKGROUND AND PURPOSE Percutaneous transluminal angioplasty (PTA) for significant stenosis involving the origin of the vertebral artery is now a well established treatment for selected patients when posterior cerebral arterial circulation is compromised. Arterial spasm, dissection, and restenosis may occur in some instances, with subsequent hemodynamic(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)
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. Two sets of different-sized and curved polytetrafluoroethylene tubes were studied. To simulate the aneurysm neck, a small hole was(More)
BACKGROUND AND PURPOSE The management of unruptured intracranial aneurysms remains controversial and the results of endovascular treatment are not precisely known because no prospective data exist. The first prospective multicenter study (ATENA) was conducted in Canada and France to determine clinical outcome and risks of this treatment. METHODS Six(More)
We report the endovascular treatment of a dural carotid cavernous fistula in a 67-year-old woman in whom superior petrosal sinus catheterization was performed to access the venous site of the fistula. To our knowledge, this retrograde venous route via the superior petrosal sinus has not been previously described.
PURPOSE To retrospectively evaluate the immediate and long-term clinical results, as well as the angiographic results, of occlusion of middle cerebral artery (MCA) berry aneurysms with coils. MATERIALS AND METHODS This retrospective study had institutional review board approval, and informed consent was obtained. One hundred fifty-four MCA aneurysms in(More)
Endovascular treatment of ruptured wide-neck bifurcation aneurysms presents a challenge. While still under evaluation, the Woven Endobridge (WEB) aneurysm embolization system has so far shown promising results in the treatment of complex bifurcation aneurysms. We aimed to evaluate the feasibility and short-term follow-up of endovascular treatment of(More)
BACKGROUND AND PURPOSE Substantial intraoperative bleeding during surgical removal of head and neck paragangliomas may be a major problem in the management of these highly vascularized tumors. Traditional preoperative embolization via a transarterial approach has proved beneficial but is often limited by complex vascular anatomy and unfavorable locations.(More)
