A Comparison of Cyclic Manual Direct Aspiration Thrombectomy (Plunger Technique) vs. Static Manual Direct Aspiration Thrombectomy for Treatment of Acute Large Vessel Occlusion Stroke (NCT07231380)
Plunger Stroke Trial: A Comparison of Cyclic Manual Direct Aspiration Thrombectomy (Plunger Technique) vs. Static Manual Direct Aspiration Thrombectomy for Treatment of Acute Large Vessel Occlusion Stroke With the Raptor Aspiration Catheter
🩺 Plain-English Summary (8th-Grade Level)
This prospective, randomized controlled trial will compare two manual aspiration techniques for treating acute ischemic stroke due to large vessel occlusion: cyclic aspiration (Plunger technique) and static aspiration. Both techniques use FDA-approved devices (Raptor Aspiration Catheters and VacLok syringes) and are standard of care. Approximately 500 participants across 20 sites will be randomized to one of the two techniques. The primary endpoint is First Pass Effect (TICI 2c/3 after first attempt), with secondary endpoints including overall recanalization and 90-day functional outcomes. Results will address a critical gap in optimizing aspiration thrombectomy techniques.
