[Transient ischemic attacks in the carotid system: main angiographic findings].

The clinical material of this report includes 100 cases of TIAs, studied with angiographic investigations in the past four years: lesions in the carotid system were more common (78%) than in the vertebro-basilar system (22%). Ulcerative and stenotic atheromatous plaques of the carotid artery were the more frequent alterations in our cases of TIAs in the carotid system. Thrombosis of the internal carotid artery was fairly frequent. Angiographic investigations used in our patients are presented.
