Radiologic control of operative carotid dilatation. Aneurysm formation following balloon dilatation

Dilatation of the dysplastic internal carotid artery has been controlled by intraoperative radiography including angiography. The method minimizes the risk of damaging the artery at the base of the skull while allowing immediate visualisation of the results. In one case persisting stenosis after passage of a metal dilator was treated by balloon dilatation with the formation of a localised aneurysm.
