[Orbital arteriovenous anastomoses].

Separate angiography of the channels of a. carotis externa and a. carotis interna revealed two cases with orbital arteriovenous anastomoses between the branches of a. maxillaris interna and v. ophthalmica inferior. In one of these cases the fistule was additionally supplied with blood by branches of a. ophthalmica. The clinical picture of arteriovenous anastomoses of the orbit resembles that of carotid-cavernous fistules. Surgical management consisted in embolization of the channel of a. maxillaris interna on the side of the anastomosis with muscular emboli. The vascular murmur and exophthalmos disappeared after the operation.
