Stentrievers potentially restore flow before clot retrieval and reduce procedural time. We aimed to study the impact of these potential benefits. Methods Acute stroke patients treated with endovascular procedures in 2 stroke centers were studied. According to device availability patients were respectively treated either with IA-tPA(IAT), Merci or Stentrievers(ST). We defined time to initial flow restoration as time from symptom onset to first pass of contrast to previously occluded arteries either through the deployed device or after recanalization. Complete recanalization(TICI>2b), day 5 NIHSS and favorable outcome at three months(mRS≤2) were re-corded. Results A total of 313 patients were studied: 127 IAT, 119 Merci, 69 Stentriever(26 Trevo, 43 Solitaire). No major differences were observed in baseline characteristics according to treat-ment groups. Rate of complete recanalization was higher with ST(67.2%) than with IAT(50.8%) or Merci(57.3%)(p=0.05). Time from groin puncture to final recanalization was lower with ST(88±46 min) than with IAT(103±70min) or Merci(128±62min)(p<0.01). Time from groin puncture to initial flow restoration was shorter with ST(36±18min) than with IAT(92±67min) or Merci(114±57min) (p<0.01). Discharge NIHSS was lower in the ST group(7, IQR:1-26) as compared to IAT(14, 2-30) or Merci(12, 5-30)(p=0.05) and rate of favorable outcome was higher: ST(52.9%) Vs IAT(33.9%) and Merci(40%)(p=0.03). The use of a stentriever increased the odds of favorable outcome(OR:1.9 95%CI: 1.04-3.39; p=0.037). Conclusion In acute endovascular treatment of stroke the use of sten-trievers may increase recanalization and reduce time to flow restoration leading to improved out-comes.
