Reversible Cerebral vasoconstriction syndrome associated with the use of sibutramine

Abstract

The reversible cerebral vasoconstriction syndrome, also known as Call-Fleming syndrome, was initially described in 1988, and is characterized by a clinical syndrome of headaches episodes, generally the “thunderclap” pattern, due to a deregulation of the vascular tonus, leading to segmentary cerebral vasoconstriction and secondary neurological deficits, including those by ischemic or hemorrhagic stroke. In this paper, we present two illustrative cases of this syndrome due to the use of sibutramine. To our knowledge, this situation hasn’t been described as related drug before.
