  • Look Inside

The purpose of this investigation was to study the indication of cerebral angiography in recent opera-tions for cerebral aneurysms. Cerebral angiography has been used for diagnoses and operations for cere-bral aneurysms, but, as the diagnostic procedures such as magnetic resonance angiography (MRA) andthree dimensional computed tomographic angiography (3D-CTA) have made remarkable progress, cerebralangiography is not always an indispensable diagnostic tool for cerebral aneurysm operations.

One hundred nineteen patients (including 40 patients with ruptured aneurysms) Out of 163 patients(including 61 patients with ruptured aneurysms) were diagnosed and operated on following MRA and 3D-CTA. All of these cases of cerebral aneurysms were operated uneventfully without the need for cerebralangiography.

We concluded that cerebral angiography is not needed for diagnoses and operations of small commoncerebral aneurysms such as middle cerebral artery aneurysms, internal carotid artery-posterior communicat-ing artery aneurysms and anterior communicating artery aneurysms. Cerebral angiography is necessaryonly in relatively large aneurysms to confirm the dynamic circulation of the cerebral blood flow beforeoperation.
