A contribution to the controversy over dimethyl sulfoxide toxicity: anesthesia monitoring results in patients treated with Onyx embolization for intracranial aneurysms

Abstract  Onyx injection is a new technique for embolization of cerebral aneurysms that is involved in a controversy about the toxicity of its solvent, dimethyl sulfoxide (DMSO). We retrospectively studied 38 patients treated for aneurysms with
