Meningeal Arteriovenous Fistulae
The first group, now clearly understood, is represented by the purely meningeal arteriovenous fistulae. We have seen 14 cases of this type at the Salpetrière Hospital, and 22 at the Lariboisière Hospital. If the traumatic fistulae are excluded, it is clear that hyper-selective artériographie studies and careful exploration of the draining veins will enable us to identify four major categories.
The second group consists of the mixed meningeal arteriovenous fistulae, i.e. meningeal-cutaneous and bony or meningeal-cortical.
