Abstract
The clinical experience of DSA of the head and neck in more than 1,000 patients is presented. In a comparative study of 100 conventional carotid angiograms, the accuracy rate in evaluating extracranial carotids was 97% in technically satisfactory studies. Intra cranial vessels were examined in 55 patients with both conventional selective catheterization and intravenous DSA. In 65% of the patients, the DSA examination was diagnostic. DSA is a safe, rapid procedure that can be performed on an outpatient basis and provides diagnostic information comparable to conventional angiography.
