Abstract Number: Esoc2026a593 the Trade-Off Between Triage Precision and Reperfusion Speed: Pre-Transfer Cta Reduces Futile Transfers but Delays Transfer Efficiency in Acute Ischemic Stroke
Randomized trial analyzes the impact of pre-transfer CTA on EVT yield and transfer efficiency in stroke patients, suggesting workflow optimization is necessary.
Key Points
To evaluate the effects of pre-transfer CTA on EVT eligibility and the impact of workflow delays at PSCs in acute ischemic stroke.
Analyzed 316 acute ischemic stroke patients transferred via the Tainan-Chiayi Stroke Network (2021–2025).
Stratified patients by CTA timing: pre-transfer (PSC-CTA) versus post-transfer (CSC-CTA).
Defined futile transfer and analyzed reasons for transfer failures.
The PSC-CTA group had a significantly higher EVT yield (73.1%) compared to the CSC-CTA group (34.1%; P<0.001).
PSC-CTA increased door-in–door-out time (139 minutes) but decreased door-to-EVT time (87 minutes) compared to CSC-CTA.
Functional outcomes at 3 months were numerically higher in the CSC-CTA group (32.5% vs. 28.3%), though not statistically significant.
