The crux of platelet function testing for neuroin-terventional (NI) procedures is to reduce the thromboembolic complication rate by individualizing platelet inhibition. There are few data to support this practice in routine NI care. Results of large (>2000 patients) randomized controlled mul-ticenter trials in the cardiology literature do not show overall clinical outcome benefit to modification of antiplatelet therapy in patients who have a poor response to antiplatelet therapy compared with standard antiplatelet therapy without monitoring. Overall, the use of point of care platelet function testing in routine NI care seems unjustified.
