Recently digital subtraction angiography (DSA) has been widely used for diagnosis of neurosurgical and circulatory diseases, however, reports of application in the oro-maxillo-facial area are rare. The authors applied DSA to several patients with diseases of the oro-maxillofacial area and obtained clear images in the cases of a hemangioma of the palatal region and occlusion of the caroted artery. The cases with intraarterial catheterization for cancer chemotherapy were examined using intraarterial digital subtraction angiography (IADSA). The tip of infusion tube and distribution of the drug were shown clearly by the IADSA.
DSA can be performed easily and safely even on outpatients. For this reason DSA seems to be useful in oro-maxillo-facial arca.
