Origin of spinal arteriovenous malformation and normal cord vasculature from a common segmental artery: angiographic and therapeutic considerations.
The dural type of spinal arteriovenous malformation (AVM) can be cured by excision or by embolization of the nidus. The common origin of the blood supply to the malformation and to the cord from the same segmental artery would profoundly affect therapeutic choices. This anatomic situation was encountered in two of nine such lesions. The angiographic appearance and the importance of recognizing this common origin is discussed.
