We excluded patients in stentriever-based randomized trials/registries. The four most commonly utilized aspiration catheters were analyzed, and multivariate logistic regression analyses were performed to determine the effect of primary aspiration catheter choice on first-pass success, final reperfusion, and modified Rankin Scale (mRS) score at 90 days.Results Of 464 large vessel thrombectomies, 180 were performed via MAT on the first pass with one of four catheters. First-pass success was achieved in 42% of cases overall; this rate did not differ significantly between catheters: 50% for Sofia, 45% for CAT6, 40% for 0.072 inch Navien, and 36% for ACE68, p=0.67. Final Thrombolysis in Cerebral Infarction 2b or 3 reperfusion was achieved in 94% of cases overall: 97% of cases with CAT6, 95% with Sofia, 92% with Navien, and 92% with ACE68, p=0.70. Mean number of passes for index thrombus (2.0 overall), median procedure time (32 min overall), 90-day good outcome (mRS 0–2, mean 36%), and 90-day mortality (mean 27%) did not differ significantly between patients treated with different initial catheters.Conclusion Among large-bore aspiration catheters, catheter selection is not an independent predictor of first-pass success, final reperfusion, or clinical outcome.
