Abstract
In the majority of patients suffering spontaneous subarachnoid hemorrhage, cerebral angiography is a safe and essential diagnostic procedure. Rupture of an intracranial aneurysm during angiography is very rare. A case of rupture of intracranial aneurysm during angiography is presented. Carotid angiograms showed extravasation of contrast material in the subarachnoid space of the base of the brain. The literature was reviewed and possible mechanisms were briefly discussed.
