Rebleeding of Cerebral Aneurysm during Three-Dimensional Computerized Tomographic Angiography

The authors report a 59-year-old woman who presented with diffuse subarachnoid hemorrhage and focal intracerebral hemorrhage in the right frontotemporal region with intraventricular hemorrhage after the right middle cerebral artery bifurcation aneurysmal rupture. The aneurysm was rebled during the 3-dimensional computerized tomographic angiography, which was performed 3 hours after initial attack. Although the aneurysm was successfully clipped, the patient died on the second hospital day. We discuss the risk factor of rebleeding of ruptured cerebral aneurysm and whether 3-dimensional computerized tomography angiography is a really safe method of detection of cerebral aneurysm in terms of rebleeding.
