Abstract
BACKGROUND: Successful resection of arteriovenous malformation (AVM) depends on preoperative assessment of the detailed morphology of the AVM. Simultaneous detailed three-dimensional (3D) visualization of the feeding arteries, draining veins, and surrounding structures is needed. In OBJECTIVE: Tthe present study, we aimed to evaluated the usefulness of high-resolution 3D multi-fusion medical imaging (hr-3DMMI) for preoperative planning of AVM.
METHODS: Hr-3DMMI combined magnetic resonance imaging (MRI), MR angiography, thin-slice computed tomography, and 3D rotated angiography. Surface rendering was mainly used for the creation of hr-3DMMI using multiple thresholds to create 3D models. Our hr-3DMMI technique was used in 8 patients for preoperative planning and the imaging findings were compared with the operative findings.
RESULTS: All feeding arteries and draining veins were found intraoperatively at the same position as estimated preoperatively and were occluded as planned preoperatively.
CONCLUSIONS: Our hr-3DMMI technique could demonstrate the precise locations of feeding arteries, draining veins, and surrounding important tissue, such as corticospinal tract and arcuate fiber, preoperatively, and estimate the appropriate route for resection of the AVM. hr-3DMMI is expected to be a very useful support tool for surgery of AVM.
