title: [Spontaneous closure of traumatic carotid-cavernous sinus fistulae--an effect of angiography?].
abstract: In two patients with a traumatic carotid-cavernous fistula, permanent occlusion of the lesion was observed following cerebral angiography and confirmed by further angiography. A delay is therefore recommended between performing angiography and carrying out further treatment, which may carry some risk. Possibly the use of ionic contrast media, which irritate the vessels, compression of the carotid artery, which reduces flow through the fistula, and general anaesthesia, which may drop the blood pressure, initiate thrombosis in the cavernous sinus.
