Abstract W P15: ADAPT Technique: A Direct Aspiration First Pass Technique for Stroke Thrombectomy
Background: The development of new revascularization devices has improved recanalization rates and time. We report our initial results with a new technique utilizing a direct aspiration first pass technique with large bore aspiration catheter as the primary method for vessel recanalization.
Methods: A retrospective evaluation of a prospectively captured database of 81 patients at 6 institutions was performed on patients where the ADAPT technique was utilized. The device manufacturer suggested retail prices was tracked for all devices used during the procedure. The data represents the initial experience with this technique.
Results: The ADAPT technique alone was successful in 63 of 81 (78%) cases. Eighteen cases required the additional use of a stent retriever or a Penumbra aspiration separator to achieve recanalization. The average time from groin puncture to at least TICI 2b recanalization was 34 minutes and 93% of cases were successfully revascularized. TICI 3 recanalization was achieved 53% of the time. On average, patients presented with an admitting NIHSS of 16 and improved to NIHSS of 6 by the time of hospital discharge. There were three procedural complications, none resulting in clinical sequelae.
Discussion: This initial experience highlights the importance of the technique with which new stroke thrombectomy devices are used may be as crucial as the device itself. The ADAPT technique is a fast, simple and effective first approach to acute ischemic stroke thrombectomy. Utilizing the latest generation of large bore aspiration catheters in this fashion has allowed us to achieve excellent clinical and angiographic outcomes.
