متن کاملSaccular aneurysms in basilar artery fenestration.
Of 59 cases of vertebrobasilar junction aneurysms diagnosed and treated from January 1977 to April 1986, 21 (35.5%) saccular aneurysms arose in a fenestration of the proximal basilar artery. Defects of the media at the junctures of the fenestrated segments, as well as the possible presence of turbulent flow at the vertebrobasilar junction, may explain the high incidence of vertebrobasilar aneur...
متن کاملBasilar artery fenestration associated with aneurysms treated by endovascular approach
Introduction: Arterial fenestrations are associated with saccular aneurysms that are often difficult to treat with open surgical techniques. Basilar artery fenestration reported in the literature is highly variable depending on the technique used. Typically fenestration occurs at the lower end of the basilar artery just at the vertebral arteries join. For basilar artery fenestrations associated...
متن کاملBasilar artery fenestration.
The posterior circulation of the brain constitutes the vertebrobasilar system and its branches, which are responsible for about 30% of the brain's blood supply. The aim of this study was to describe the anomalies of the basilar artery, especially fenestrations. For that purpose, we examined 50 patients with computed tomography (CT) angiography during an 8-month period. In the CT reports of 2 (4...
متن کاملNatural history and management of basilar trunk artery aneurysms.
BACKGROUND AND PURPOSE Basilar trunk aneurysms (BTAs), defined as aneurysms distal to the basilar origin and proximal to the origin of the superior cerebellar artery, are rare and challenging to manage. We describe the natural history and management in a consecutive series of BTAs. METHODS Between 2000 and 2013, 2522 patients with 3238 aneurysms were referred to our institution for aneurysm m...
