Thrombectomy with embed aspiration in acute ischaemic stroke.

BACKGROUND:In addition to stent retrievers, direct aspiration has become a reasonable thrombectomy strategy. OBJECTIVES:We carried out the thrombectomy by guiding the aspiration catheter fully over the clot and performing immediate manual aspiration; we call this procedure "embed aspiration". METHODS:In this prospective, non-randomised, single-centre study, we included all patients treated at a high volume-of-care stroke centre between 2017 and 2018 for the TRIANA (Thrombectomy in Andalusia using Aspiration) registry. Thrombectomy was carried out by embed aspiration. Patients were classified according to the success (eTICI 2b67-2c-3) or failure (eTICI 0-1-2a-2b50) of the procedure. Baseline clinical data and outcomes were compared, and multivariate analysis was performed. RESULTS:The embed aspiration technique was used in 370 patients. Treatment was successful in 90.3% of patients. Mean puncture-to-recanalisation time was 25 minutes. The overall rate of good outcomes (mRS 0-2) at 3 months was 64%. CONCLUSIONS:This study supports real-life evidence that standardised embed aspiration may be an alternative to stent retrievers for thrombectomy.
