NEW ORLEANS—Patients who were selected for endovascular stroke interventions on the basis of CT perfusion (CTP) imaging experienced significantly longer times between CT acquisition and groin puncture and reperfusion than patients selected on the basis of noncontrast CT imaging did, according to research presented at the 2012 International Stroke Conference. The mean time between CTP and reperfusion was 223 minutes, and the mean time between noncontrast CT and reperfusion was 175 minutes.
Patients selected for endovascular intervention on the basis of CTP experienced symptomatic hemorrhage at a rate of 6.8%, compared with a rate of 6.6% for patients selected on the basis of CT. Approximately 37% of patients who received intervention on the basis of CTP had good outcomes, compared with nearly 39% of patients imaged with noncontrast CT. Final infarct volume for patients selected through CTP was 80 cm3, compared with 88 cm3 for patients selected through noncontrast CT.
