A review of a series of 312 giant intracranial aneurysms treated at University Hospital in London, Ontario, showed that 93 of those aneurysms were located between the intracavernous portion and the bifurcation of the internal carotid artery. Sixty-five of those aneurysms were carotid ophthalmic, 12 were located in the internal carotid-posterior communicating-anterior choroidal artery regions and 16 involved the internal carotid artery bifurcation. For the majority, clinical presentation was related to the mass of the aneurysms and compression of surrounding structures such as visual pathways, ocular motor cranial nerves, the fifth nerve, and hypothalamic-pituitary axis. Fourteen patients presented with subarachnoid hemorrhage. Cerebral angiography, computed tomography and xenon inhalation studies of cerebral blood flow were the tools used to study the morphology of the aneurysm and dynamics of the circle of Willis.
对安大略省伦敦市大学医院治疗的312例巨大颅内动脉瘤病例进行回顾发现，其中93例动脉瘤位于海绵窦段与颈内动脉分叉之间。这些动脉瘤中，65例为颈内动脉眼段动脉瘤，12例位于颈内动脉-后交通动脉-脉络膜前动脉区域，16例累及颈内动脉分叉。大多数患者的临床表现与动脉瘤肿块及周围结构受压有关，如视觉通路、动眼神经、三叉神经以及下丘脑-垂体轴。14例患者出现蛛网膜下腔出血。脑血管造影、计算机断层扫描和氙吸入脑血流研究是用于研究动脉瘤形态和 Willis 环血流动力学的工具。
