Perangiographic rupture of intracranial aneurysms.

The reports of perangiographic rupture of intracranial aneurysm are very few, but the actual incidence is doubtless higher than reported. We could find only 49 cases in the literature, all of which were recognized by extravasation of contrast media. Three of our own cases are documented; in all of them cerebral angiography was carried out soon after subarachnoid hemorrhages. The danger of cerebral angiography in patients with a recently hemorrhaged intracranial aneurysm is stressed.
