Rhombencephalosynapsis is a rare congenital abnormality characterised by dorsal fusion of the cerebellar hemispheres, agenesis or hypogenesis of the vermis, fusion of dentate nuclei and superior cerebellar peduncles. We describe 9 children, aged 1.5 to 6 years, with rhombencephalosynapsis. Isolated rhombencephalosynapsis was found in 2 patients,(More)
INTRODUCTION The purpose of the present study was to determine the role of diffusion-weighted imaging (DWI) and to investigate the use of DWI in the diagnosis of brain death (BD). METHODS We prospectively evaluated 22 patients diagnosed with clinical BD (9 women, 13 men; mean age, 39.63 ± 15.1 years; age range, 9-66 years). All clinical criteria for BD(More)
OBJECTIVE This study was designed to elucidate the requirements for angiographic evaluation in blunt head injuries, the timing of angiography, and the selection of appropriate therapeutic approaches. METHODS Twelve cases of traumatic aneurysms (TAs) in the intracranial carotid tree were analyzed in this study. Neurological examination results, computed(More)
The risk of fatal injury of the internal carotid artery (ICA) and surrounding anatomy during transsphenoidal surgery for pituitary adenoma is the most severe potential complication associated with this particular approach. We present a case in which iatrogenic injury to a patient's ICA and resultant carotid cavernous fistula and massive hemorrhage was(More)
We present our initial experience with a newly developed endovascular stent graft technique in the treatment of two patients with giant aneurysms. In both of these patients, surgery and conventional endovascular techniques were likely to fail. The technique resulted in the successful management of the aneurysms in both cases. Our technique is described, and(More)
BACKGROUND AND PURPOSE Arterial fenestrations are associated with saccular aneurysms that are often difficult to treat with open surgical techniques. We evaluated our experience with endovascular treatment of such aneurysms. METHODS Ten consecutive patients with 11 basilar artery aneurysms associated with fenestrations were treated with coils by means of(More)
Advanced transluminal neurovascular navigation is an indispensable image-guided method that allows for real-time navigation of endovascular material in critical neurovascular settings. Thus far, it has been primarily based on 2D and 3D angiography, burdening the patient with a relatively high level of iodinated contrast. However, in the patients with renal(More)
BACKGROUND AND PURPOSE Thromboembolic events may occur during or after the treatment of intracranial aneurysms with Guglielmi detachable coils (GDCs). The purpose of this study was to determine the frequency of thromboembolic events associated with balloon-assisted coil placement and to investigate possible risk factors for these events during(More)
Behçet's disease (BD) is a well-known multisystem inflammatory disorder of unknown etiology. Aneurysms of the cerebral arteries are not commonly described in patients with BD. There are few cases of intracranial aneurysms with BD reported in the literature. In this study, we report endovascular treatment of BD-related ruptured intracranial aneurysms in two(More)
Vertebrobasilar insufficiency (VBI) due to vertebral artery (VA) compression occurs in a significant number of patients. Rotational compression of the VA usually occurs below C-2, where the artery is pinched during head rotation, leading to thrombus formation and subsequent cerebellar infarction. Although this problem has been reported to occur at the(More)
