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

Abstract

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

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death.
