[Elements in the objective evaluation of the carotid arteriogram]

The carotid angiography is widely used in our country, and has great importance even in those medical, neurosurgical, and neurotraumatic centers which employ the most advanced methods such as computerized tomography of the brain. To asure correct interpretation of a carotid arteriogram (thus making maximal use of such a tool) the interpreneur must have a more detailed knowledge of cephalic angiography. In the A--P picture the main elements are the infra and supraclinoid parts of the carotid, as well as the anterior and middle cerebral arteries and their branches. The authors describe these arteries and their anatomic peculiarities and changes to be expected in certain pathologic processes as illustrated by a new pictures. Of particular importance is the lateral carotid arteriogram whose changes allow diagnosis of expansive intracranial processes such as tumors and trauma.
