Cerebral Perfusion Long Term after Therapeutic Occlusion of the Internal Carotid Artery in Patients Who Tolerated Angiographic Balloon Test Occlusion

“…Also, only female patients were included in this study, attributable to the fact that there is a female predominance in the occurrence of intracranial aneurysms. 31 Although the current study population is homogeneous and the number of patients is too small to draw definitive conclusions, the results of this study do strengthen the hypothesis that in patients tolerating BTO, cerebral perfusion endures long term after therapeutic occlusion of the ICA.…”

“…First, we estimated CBF on the basis of an ASL sequence with a single TI because this sequence allows a larger imaging volume, identical to the imaging volume of selective ASL. Although the latter could introduce the risk of underestimation of CBF in the ipsilateral hemisphere due to delayed arrival of collateral flow, this was probably not the case in this study because data were acquired at a relatively long delay time of 2100 ms. Second, due to the low incidence of giant aneurysms (representing only 3%-5% of all intracranial aneurysms 9,31 ), the population included in this study was limited. Also, only female patients were included in this study, attributable to the fact that there is a female predominance in the occurrence of intracranial aneurysms.…”

Thrombosed Giant Aneurysm of the Pericallosal Artery With Inconclusive Findings of Multiple Neuroimaging Studies -Case Report-

“…1,4,5,[8][9][10]18,19) Giant pericallosal artery aneurysms are rarer, with only 15 cases reported. 1,2,[5][6][7][8][9][10][12][13][14][15]17,18,20) Giant aneurysms show a high incidence of thrombus formation, which causes difficulties in the differential diagnosis between giant aneurysms and other mass lesions including hematomas associated with vascular malformation and tumors based on cerebral angiography, computed tomography (CT), and magnetic resonance (MR) imaging. 2,10,12,14) We report a case of almost totally thrombosed giant pericallosal artery aneurysm that appeared to be recurring hematoma originating in a cavernous malformation or an avascular tumor with obliteration of the pericallosal artery on cerebral digital subtraction angiography (DSA), CT angiography, and MR imaging.…”

Use of Flow-Diverting Devices in Fusiform Vertebrobasilar Giant Aneurysms: A Report on Periprocedural Course and Long-Term Follow-Up

“…The incidence of FVBGAs is estimated to be only Ͻ1% of all intracranial aneurysms. [1][2][3][4][5][6][7][8][9][10][11][12] Little is known about the natural history of FVBGAs, but the data available indicate poor outcome and continuous progression of aneurysm size and related symptoms (brain stem compression, brain stem ischemia, subarachnoid hemorrhage in particular). 13,14 The treatment of FVBGAs presents enormous challenges.…”
