Abstract

OBJECTIVE: Perfusion studies are increasingly used to triage acute stroke patients for endovascular recanalization therapies. We compare the safety and efficacy of CT perfusion (CTP)-guided to time-guided mechanical recanalization in acute ischemic stroke (AIS) patients.

METHODS: A review was conducted on 132 patients, 94 undergoing CTP-guided and 38 undergoing time-guided (maximum 8h from symptom onset) mechanical recanalization at our institution.

RESULTS: The rate of partial-to-complete recanalization did not differ between the CTP and the non-CTP group (78.7% vs. 81.6%, respectively, p=0.71). ICH occurred respectively in 18.1% in the CTP group versus 31.6% in the non-CTP group (p=0.06). The overall in-hospital mortality rate was significantly lower in the CTP group (15.9% vs. 36.8%, p=0.04). In multivariable analysis, CTP-guided patient selection was an independent negative predictor of in-hospital mortality (OR=3.2; p=0.01). CTP-guided patient selection, however, was not a predictor of favorable outcome (Modified Rankin Scale 0-2 or 0-3).

CONCLUSIONS: CTP-based patient selection was associated with lower ICH and mortality rates. Favorable outcomes, however, did not differ between the 2 groups. These results may suggest a possible benefit in terms of in-hospital mortality with CTP-guided triage of AIS patients for endovascular treatment.
