Surgical Treatment of Multiple Intracranial Aneurysms

AIm: To discuss the surgical methods for multiple intracranial aneurysms. mATeRIAL and meTHods: 23 patients were divided into three groups according to the location of the aneurysms: aneurysms located in one side or in the midline of the Willis ring; aneurysms located on both sides of the Willis ring with unruptured aneurysms located ahead of the middle cerebral artery bifurcation; and MIAs located on both sides with unruptured aneurysms located in the middle cerebral artery bifurcation or distal bifurcation. The preoperative operation strategy was made according to different groups. ResuLTs: All patients in the first group underwent a one-stage operation for occlusion of all aneurysms. In the second group, eight patients underwent a one-stage operation for occlusion of all arterial aneurysms while the other three patients underwent a one-stage operation for occlusion of the ipsilateral aneurysms, followed by a two-stage operation for occlusion of the contralateral arterial aneurysms. In the third group, all patients underwent a two-stage operation for occlusion of all aneurysms. Good recovery, moderate disability, and severe disability were observed in 19, 2, and 2 cases, respectively. CoNCLusIoN: One-stage or two-stage surgery was determined based on the distribution of multiple aneurysms and the intraoperative situation to achieve ideal treatment effects.
