The technical feasibility of the rocket technique was evaluated for patients treated for stroke where the direct aspiration first-pass technique (ADAPT) failed to reach the occlusion site. This single-center retrospective study included data on consecutive patients with a large vessel occlusion of the anterior circulation who underwent mechanical thrombectomy. Of 138 patients, 100 met the inclusion criteria. In 84 patients, a large 0.072-inch inner lumen aspiration catheter was able to reach the occlusion site when deployed with a coaxial microcatheter. In 16 patients, this technique failed, and the microcatheter was replaced with a compliant balloon inflated at the extremity of the aspiration catheter (rocket technique). In 15 of these 16 patients, the rocket technique brought the catheter into contact with the thrombus. In conclusion, when deployment of the ADAPT with a coaxial microcatheter fails to reach the clot site, the rocket technique can safely advance the aspiration catheter to the clot.
该火箭技术的技术可行性在接受直接抽吸首过技术（ADAPT）治疗但未能到达闭塞部位的卒中患者中进行了评估。这项单中心回顾性研究纳入了接受机械血栓切除术的前循环大血管闭塞的连续患者的数据。在 138 名患者中，有 100 名符合纳入标准。在 84 名患者中，当使用同轴微导管部署时，能够到达闭塞部位的是大 0.072 英寸内管腔抽吸导管。在 16 名患者中，该技术失败，微导管被可膨胀至抽吸导管末端的顺应性球囊取代（火箭技术）。在这 16 名患者中的 15 名中，火箭技术使导管与血栓接触。总之，当同轴微导管的 ADAPT 部署无法到达血栓部位时，火箭技术可以安全地将抽吸导管推进血栓。
