Abstract:Background:
Reversible cerebral vasoconstriction syndrome (RCVS) is a self-limited entity with usually benign outcome. Over 30% RCVS patients develop subarachnoid hemorrhage (SAH). We aimed to identify features that differentiate RCVS-SAH from more ominous causes of SAH, i.e. aneurysmal SAH (aSAH) and cryptogenic ‘angio-negative’ SAH (cSAH).
Methods:
We compared the clinical-imaging features of 38 consecutive RCVS-SAH patients, to 515 aSAH and 93 cSAH p… Show more
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.
