Therapeutic options for acute ischemic stroke patients presenting on effective anticoagulation are limited. Idarucizumab, a humanized, monoclonal antibody fragment for immediate reversal of dabigatran, may allow this subgroup of orally anticoagulated patients to regain eligibility for thrombolysis. ⋯ This case represents a new therapeutic paradigm. It is further supported by in vitro data showing no nonspecific interactions of idarucizumab with recombinant tissue-type plasminogen activator-induced thrombolysis. Thus, patients effectively anticoagulated with dabigatran who were previously contraindicated for thrombolytic therapy in this situation may now receive treatment because of the ability to rapidly reverse the anticoagulant activity of dabigatran with idarucizumab.

To compare hemorrhagic and nonhemorrhagic reversible cerebral vasoconstriction syndromes (RCVS) with a view to understand mechanisms. ⋯ ICH and cSAH are common complications of RCVS. Triggers and risk factors do not predict lesion subtype but may alter central vasomotor control mechanisms resulting in centripetal angiographic evolution. Early distal vasoconstriction is associated with lobar ICH and cSAH, and delayed proximal vasoconstriction with infarction.
