    Abstract:
    A case of intracranial traumatic aneurysms occurring after surgical treatment of a large cerebral aneurysm is reported. A 56-year-old man was admitted to our department with complaints of headache, nuchal pain and nausea. Left carotid angiography (Lt-CAG) revealed a large aneurysm, measuring 20 mm in maximum diameter, of the azygos anterior cerebral artery. Successful clipping operation was performed on day 17 of subarachnoid hemorrhage. Unfortunately, small cortical branches were pulled out during the procedure from the right pericallosal artery. The postoperative Lt-CAG showed formation of two other aneurysms. Second operation was done on day 28 after the first operation. These aneurysms were located at the previously injured sites on the right pericallosal artery. From the history sited above, we diagnosed them as traumatic aneurysms. The second operation resulted in successful obliteration of these two traumatic aneurysms. Literature review yielded 25 similar cases, and the authors discuss the etiologic factors of the traumatic aneurysm due to surgical procedure.
