P-034 First pass recanalization: incidence, predictors, and outcome

Abstract

Introduction Recanalization with the first pass is known to improve mechanical thrombectomy outcome and lower complications rate. We report the outcome and predictors of first pass recanalization using ADAPT technique. First pass recanalization (FP) is defined as achieving successful recanalization (mTICI ≥2b) with first aspiration attempt. Methods The A Direct Aspiration First Pass Technique (ADAPT) database was used to identify a subgroup of patients who achieved FP. Baseline characteristics, procedural, and postprocedural variables were collected. Outcome measures included 90 days modified Rankin scale (mRS), mortality and any hemorrhagic complications. Multivariate logistic regression was used to identify FP predictors. Results A total of 524 patients were included of whom 178 achieved FP. More patients in the FP group received IV tPA (46.6% vs 37.6%; p Conclusion Recanalization with first aspiration pass associated with better functional outcome and lower mortality rate. IV tPA and use of larger aspiration catheters associated with FP. Disclosures M. Anadani: None. A. Alaweih: None. R.
