Application of fluorescein sodium videoangiography in aneurysm surgery.

Background: The use of fluorescent technologies in vascular neurosurgery emerged after indocyanine green video angiography (ICG-VA) was first described in 2003. As data supporting the efficiency of ICG in preventing postoperative complications has grown substantially, it has now established itself as the standard of care. However, the predominant literature centers on ICG techniques, leaving the evaluation of cost-effective fluorescein tools pending.

Infratentorial Cerebral Cavernous Malformation May be a Risk Factor for Symptomatic Bleeding and Precocity of Symptoms: A Multicenter, Propensity Score Matched, Case-Control Study.

Background: Cerebral Cavernous Malformation (CCM) is one of the most common types of vascular malformation of the central nervous system. Intracerebral hemorrhage, seizures, and lesional growth are the main clinical manifestations. Natural history studies have tried to identify many risk factors; however, the clinical course remains highly unpredictable.
