Introduction Despite the growing use of aspiration through large bore catheters when performing a mechanical thrombectomy (MT), stents remain an important tool to achieve successful recanalization. Whether used as a primary technique or as a bail out method, stent retrievers have been shown to improve outcomes and reperfusion rates for acute ischemic stroke (AIS) patients undergoing MT. The goal of the study was to assess the feasibility of deploying TREVO NXT through the FastPass delivery assist catheter, part of the super-bore Broadway System.Methods A silicon vessel ‘frisbee’ model was placed under a monoplane in the operating room. Under fluoroscopic guidance, ten 3 mm x 32 mm Trevo devices were deployed in the M1 segment of the middle cerebral artery through the FastPass. Prospectively collected data including three variables were obtained including operator’s control of deployment, resistance when advancing stent through FastPass, and resistance when retracting stent with FastPass out of Broadway 8. Scores ranged from 1-5, with 3 representing comparable feel to the standard microcatheter which would have been used otherwise.Results Ten 3 mm x 32 mm Trevo devices were successfully deployed in the M1 segment of the middle cerebral artery under fluoroscopic guidance. No device related issues were recorded. When comparing delivery of TREVO devices through the FastPass compared to standard microcatheters the performance was similar ( table 1).Discussion This study shows the feasibility of deploying TREVO NXT through the FastPass insert catheter, part of the super-bore Broadway System. The ability to use the packaged delivery catheter, FastPass, as a deployment catheter for stent retrievers allows for operator flexibility during a thrombectomy. An operator can use a stent retriever as a primary method with the superbore system or as a bail out method if primary aspiration has not achieved successful reperfusion without the need to open another microcatheter reducing total procedural expenses and time.Disclosures T.
