BACKGROUND: The development of frameless stereotaxis allows for repetitive intraoperative localization with millimeter accuracy. High-resolution computed tomographic (CT) angiography provides multiplanar, three-dimensional imaging of cerebral vascular lesions. The image data set generated during CT angiography can be used for localization in frameless stereotaxis when performed with appropriate fiducials in place.
METHODS: The feasibility of melding these two technologies was tested on a patient with a small (5 mm), distal ruptured posterior inferior cerebellar artery aneurysm, which was visualized by CT angiography and localized by frameless stereotaxis.
RESULTS: Visualization by CT angiography and intraoperative localization by frameless stereotaxis were successful.
CONCLUSIONS: The practical application of this technology meld is demonstrated in this sample case. Applications to distal anterior cerebral artery aneurysms, abnormal flow-related aneurysms associated with arteriovenous malformations, and mycotic aneurysms are discussed.
