Purpose : The usefulness and radiographic findings of the angiography in cerebral infarction are well known.We attempted to evaluate the angiographic causes, findings, and the usefulness of DSA in cerebral infarction.Matherials and Methods : The authors reviewed retrospectively DSA images of 51 patients who were diagnosed ashaving cerebral infarction by brain CT and/or MRI and clinical settings. DSA was performed in all 51 patients, andin 3 patients, conventional angiogram was also done. Both carotid DSA images were obtained in AP, lateral, obliqueprojections, and one or both verebral DSA images in AP and lateral,. The authors rviewed the patient's charts forsymptoms, operative findings and final diagnosis, and analysed DSA findings of cerebral atherosclerosis with focuson 6 major cerebral arteries. Results : Among the 51 patients of cerebral infarction 43 patients (84.3%) hadcerebral atherosclerosis, 1 dissecting aneurysm, 1 moyamoya disease and 6 negative in angiogram. DSA findings ofcerebral atherosclerosis were multiple narrowings in 42 patients (97.7%), tortuosity in 22 (51.2%), dilatation in14, occlusion in 12, avascular region in 8, collaterals in 7, ulcer in 6, and delayed washout of contrast media in3. In cerebral atherosclerosis, internal carotid artery was involved in 37 patients (86.0%), middle cerebralartery in 29 (67.4%), posterior cerebral artery in 28, anterior cerebral artery in 26, vertebral artery in 22, andbasilar artery in 15. Intracranial involvement of cerebral atherosclerosis (64.9%) was more common thanextracranial involvement (16.2%). Conclusion : In cerebral infarction MRA may be the screening test, but for moreprecise evalation of vascular abnormality and its extent, DSA should be considered.
