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)
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)
PURPOSE To evaluate the endovascular treatment (EVT) of mycotic aneurysms (MAs). MATERIALS AND METHODS Clinical and radiologic data of 18 MAs treated with EVT were retrospectively reviewed. There were 14 patients (11 men, three women), ranging in age from 28 to 64 (mean age, 44 years). All patients had endocarditis and positive blood culture. The(More)
SUMMARY Three cases of spontaneously closing dural arteriovenous fistulas (AVFs) are presented, and 11 previously published cases are reviewed. On the basis of clinical and angiographic data, two types of spontaneously regressing dural AVFs are distinguished: posttraumatic and spontaneous. In all cases, the explanation for spontaneous closure is unknown.(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)
Tortuous vasculature is a cause of failure of endovascular treatment of intracranial vascular lesions. We report our experience of direct cervical accesses in patients in whom the arterial femoral route was not attainable. In this retrospective study, 42 direct punctures of the carotid or the vertebral arteries at the neck were performed in 38 patients. The(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)
PURPOSE The purpose of this study was to evaluate the reliability of angiography-based balloon test occlusion (BTO) criteria to decide whether to perform internal carotid artery (ICA) permanent occlusion. METHODS From March 1999 to August 2004, 60 patients underwent therapeutic ICA occlusion. Angiographic BTO was performed systematically in all patients(More)
BACKGROUND AND PURPOSE Radiation-induced stenoses of the carotid artery are associated with fibrosis of the arterial layers and tissue planes that renders their surgical treatment difficult. We present our clinical experience in carotid angioplasty stenting (CAS) of patients harboring such stenoses. METHODS Seven patients underwent transfemoral CAS of 10(More)
