Management of DCI is presented here as a three-stage algorithm. Tier One therapy should be initiated for new DCI which can manifest as neurological deterioration, characteristic imaging findings or MMM abnormalities indicating ischemia. Tier Two therapy hsould be started in cases of refractory DCI(inadequate reversal of ischemia after first-line therapy.)
