Endovascular embolisation is a safe and successful minimally-invasive method to treat arterial injuries occurring through THA. Therefore, it should be considered as a first-line option of treatment for those injuries.
Transient cortical blindness (TCB) is a rare complication after cerebral or coronary angiography. In this article, we elaborate the condition and present a case which occurred in our hospital. With increasing numbers of diagnostic angiographies and endovascular interventions, we want to raise awareness of TCB and its clinical course. We report about a 57-year-old woman with TCB after a diagnostic digital subtraction angiography (DSA) and endovascular treatment of a ruptured aneurysm of the basilar tip. Symptoms disappeared spontaneously after 36 h with no residual deficits. Multimodal imaging including non-contrast enhanced cerebral CT-scan (NECT), cerebral magnetic resonance imaging (cMRI), and cerebral DSA are presented. Despite the seemingly grave event, the prognosis of this condition can be considered as excellent. The exact pathophysiology remains speculative, but might be related to contrast agent neurotoxicity with transient disruption of blood brain barrier integrity. Immediate computed tomographic angiogram (CTA) and CT-scan or magnetic resonance angiography (MRA) and cMRI should be performed after an occurrence of a suspected TCB to rule out embolic occlusions or hemorrhage. The administration of steroids can be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
