Cerebral aneurysmal rupture during angiography with confirmation by computed tomography: a review of intra-angiographic aneurysmal rupture.

摘要: Rupture of a cerebral aneurysm during angiography, with confirmation by computed tomography (CT), is described. A review 30 additional reported cases demonstrates no unusual profiles, the exception predominance female patients (71%), and presence pre-angiographic arterial hypertension. Experimental clinical evidence increasingly suggests that intravascular pressures are transiently elevated angiography. These changes may be enhanced increased flow rates contrast media, smaller diameters catheters, intracranial spasm, latter presenting as very prominent feature in intra-angiographic rupture. However, direct elevation intra-aneurysmal pressure has not been documented, have occurred only portion cases.
