With technical advancements, three-dimensional computed tomography (3D-CT) has been utilized frequently for cerebral aneurysms. Some investigators maintain that only 3D-CT is sufficient for preoperative examination in aneurysms, including ruptured aneurysms. We clarify the usefulness and limitations of three-dimensional digital angiography (3D-DA) for aneurysm surgery. Forty-three saccular aneurysms were included. Forty cases were ruptured, and only 3 cases were unruptured. Three-dimensional reconstructed images were obtained in these cases. 3D-DA was very useful for precise detection of the aneurysm neck and determining the relationship between the aneurysm neck and branches. But the size of the aneurysm could not be shown exactly. 3D-DA is valuable for planning the surgical treatment for cerebral aneurysms.
