Abstract

Before treating an arteriovenous fistula, it is important to understand its features, particularly the shunting point, sinus form, and drainage route. However, this can often be difficult owing to the large number of vessels that accumulate in the fistula region. In this study, we employed image fusion technology to understand the pathology of cavernous sinus dural arteriovenous fistulas (CSdAVFs) prior to treatment.

We performed the following three types of fusions on the workstation : three-dimensional rotation angiography (3DRA) images from different feeding arteries to gain a detailed understanding of fistula architecture and shunting points; three-dimensional computed tomography (3DCT) and 3DRA images for determining the correlation between the skull base bone and the sinus shunt to predict the point of shunt access ; and time-of-flight magnetic resonance imaging (TOF MRI) scans and 3DRA source images for investigating retrograde leptomeningeal venous drainage. Compared to individual images, the fused images more effectively provided a detailed understanding of CSdAVFs. Herein, we report our experience with image fusion for CSdAVF and review the relevant literature.
