[Spontaneous healing of a carotid-cavernous fistula]

In a posttraumatic carotid-sinus cavernous fistula, spontaneous healing occurred which was angiographically demonstrated. After this closure had occurred, an aneunysmal enlargement of the internal carotid was proved to exist and confirmed even two weeks later together with a concomitant spasm. The author is of the opinion that the cause of a carotid-sinus cavernous fistula is in most cases a ruptured aneurysms. By partial thrombosing of the aneurysm, a closure of the fistula occasionally takes place and thus the above mentioned spontaneous healing is reached.
