Saccular aneurysms in basilar artery fenestration.
نویسندگان
چکیده
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 aneurysms associated with proximal basilar artery fenestration.

The fenestration of the basilar artery is an uncommon anatomical variant that may be associated with saccular aneurysms; however this association is rare. We report the case of a patient who presented with subarachnoid hemorrhage that was successfully treated by coil embolization and review the literature.
متن کاملEndovascular management of basilar artery aneurysms associated with fenestrations.
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 the endovascular route between Novembe...
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...

PURPOSE To determine the association of intracranial arterial fenestration and aneurysms. METHODS We retrospectively reviewed 5,190 cerebral angiogram reports and identified 37 patients with arterial fenestrations. RESULTS These 37 patients had 38 fenestrated arteries: 16 basilar, 10 vertebral, nine middle cerebral, and three anterior cerebral arteries. Seven of these patients had a total o...

Basilar artery fenestration is infrequent and even rarer in association with a large aneurysm. With proximity to brain stem and vital perforators, endovascular coiling can be considered first. If the large ruptured aneurysm with a wide neck originated from fenestra of the proximal basilar artery and the fenestration loop has branches of posterior circulation, therapeutic consideration should be...
