Civilian Upper Extremity Vascular Injuries: An National Trauma Data Bank Study

Abstract

Conclusions: Using preoperative P2Y12 testing with a threshold of PRU $194 to define CR, we identified a high prevalence of CR in patients undergoing TCAR similar to that in the pre-existing coronary literature. We found no significant differences in postoperative ischemic or hemorrhagic complications by clopidogrel response phenotype, although complication rates in the overall study cohort were low. Further investigation is warranted to determine if a quantitative assessment of CR is sufficient to identify patients at risk of developing secondary cerebrovascular ischemic events in this patient population.
