The chief reason for the renewal of interest in this subject is the recent development of cerebral arteriography. This procedure affords an excellent means of visualization of the normal and abnormal intracranial vessels, using as a medium a 35 per cent solution of iodopyracet injection (diodrast®).

The procedure consists of the introduction of iodopyracet injection directly into the carotid artery, either by the percutaneous method or by the open procedure, with introduction of the needle into the carotid artery under direct vision. The choice of method depends on the experience of the operator and the frequency with
