Abstract

Introduction

While revascularization rates have improved for mechanical thrombectomy (MT) in acute ischemic stroke, advancements in aspiration pumps have been limited. The ALGO Smart Pump (Von Vascular, Sunrise, FL) is a small on-field, operator-driven pump offering two aspiration modes: Adaptive Pulsatile Aspiration (APA™) Mode and a continuous 'Static' mode. This study evaluates the performance of the ALGO Smart Pump's Static Mode compared to a commercially available aspiration pump.

Methods

Operators performed aspiration thrombectomy in a flow model with ALGO and the Penumbra ENGINE (Penumbra, Alameda, CA) using medium (ID.036–.057”) to large (ID.068–.071) bore aspiration catheters. Primary endpoint was complete clot ingestion (CCI), defined as the full ingestion of the clot within the catheter or pump's canister, without any clot at the catheter tip or evidence of embolization to new territories (ENT). Secondary endpoints included first pass recanalization, ENT and total aspiration time.

Results

When comparing all catheters, ALGO Smart Pump achieved CCI in 154 of 180 thrombectomies (85.6 %) compared to Penumbra ENGINE achieving CCI in 136 of 180 thrombectomies (75.6 %). The CCI rate between pump types across all catheters was statistically significant (p = 0.008), favoring ALGO pump. There was no difference between pump type on aspiration time.

Conclusion

The ALGO Smart Pump may represent an alternative in MT, with potential higher effectiveness compared to existing available aspiration pumps with additional user-friendly benefits including a sterile, smaller, on-field apparatus.

创新中风护理：ALGO智能泵在智能静态模式下的性能研究

虽然急性缺血性卒中机械取栓术（MT）的血运重建率有所提高，但吸入泵的进展有限。ALGO智能泵（Von Vascular, Sunrise， FL）是一种小型现场操作驱动泵，提供两种抽吸模式：自适应脉动抽吸（APA™）模式和连续“静态”模式。本研究评估了ALGO智能泵静态模式的性能，并将其与市售抽吸泵进行了比较。方法：操作者使用中径（ID.036 - 0.057”）到大径（ID.068 - 0.071）的抽吸导管，在血流模型中使用ALGO和半影引擎（Penumbra, Alameda， CA）进行抽吸取栓。主要终点是完全血块摄入（CCI），定义为完全摄入导管或泵筒内的血块，导管尖端没有任何血块或栓塞到新区域（ENT）的证据。次要终点包括第一次再通，耳鼻喉科和总吸入时间。结果在比较所有导管时，ALGO Smart Pump在180例血栓切除术中有154例达到CCI(85.6% %)，而Penumbra ENGINE在180例血栓切除术中有136例达到CCI（75.6% %）。各导管泵型间CCI率差异有统计学意义（p = 0.008），有利于ALGO泵。不同泵型吸痰时间无差异。结论ALGO智能泵可能是MT的一种替代方案，与现有的吸进泵相比，它具有更高的有效性，并且具有额外的用户友好性，包括无菌、更小的现场设备。
