    Introduction: Manual aspiration thrombectomy is a well-established technique for coronary disease and has recently been published as a technique for endovascular stroke therapy. Modern endovascular stroke techniques such as aspiration stroke therapy or stent-triever technology allow for either manual aspiration or pump aspiration. We sought to compare both techniques to determine which allows for the greatest force generated.

    Methods: Force of aspiration at the tip of each catheter was measured and compared. Pressure at the tip of each catheter was measured utilizing a vacuum pressure gauge while the catheter was attached to either a 60 cc syringe or a standard aspiration pump set to -29 inHg. Force was then calculated utilizing the formula P = F/A (P = pressure, F = Force, A = Area; catheter tip inner diameter).

    Results: Force of aspiration at the tip of each catheter was measured and compared. Pressure at the tip of each catheter was measured utilizing a vacuum pressure gauge while the catheter was attached to either a 60 cc syringe or a standard aspiration pump set to -29 inHg. Force was then calculated utilizing the formula P = F/A (P = pressure, F = Force, A = Area; catheter tip inner diameter).

    Conclusions: Pump aspiration generates the greatest amount of force when compared to syringe aspiration techniques. As such, pump aspiration techniques may be a more effective approach to endovascular stroke therapy than syringe aspiration.

    Patient Care: Identify the optimal technique for aspiration stroke therapy and improve efficacy of treatment and patient outcome

    Learning Objectives: Understand the optimal technique for aspiration stroke therapy
