We hypothesized that the presence of a proximal cerebral artery occlusion on CT angiography CTA is an independent predictor of the use of these services. Methods We performed a historical cohort study of consecutive ischemic stroke patients presenting within 24 h of symptom onset to an academic emergency department who underwent emergent CTA. Use of tertiary care interventions including intra-arterial IA thrombolysis mechanical clot retrieval and neurosurgery were captured. Results During the study period 207 290 71 of patients with acute ischemic stroke underwent emergent CTA. Of the patients 74 207 36 showed evidence of a proximal cerebral artery occlusion and 22 207 11 underwent an interventional procedure. Those with proximal occlusions were more likely to receive a neurointervention 26 vs. 2 p . They were more likely to undergo IA thrombolysis 9 vs. 0 p or a mechanical intervention 19 vs. 0 p but not more likely to undergo neurosurgery 5 vs. 2 p . After controlling for the initial NIH stroke scale NIHSS score proximal occlusion remained an independent predictor of the use of neurointerventional services OR 95 CI . Evidence of proximal occlusion on CTA predicted use of neurointervention with sensitivity of 82 95 CI 59-94 specificity of 71 95 .
