To describe a new device meant for rapid endovascular thrombectomy of intracranial arteries of various sizes and its first clinical use.
A device with oriented microfilaments was constructed that consists of a core wires compound surrounded by a dense palisade of perpendicular-oriented stiff polyamid microfilaments (phenox clot retriever). The device is introduced into the target vessel through a 0.021- or 0.027-inch microcatheter, deployed distally to the thrombus, and slowly pulled back under continuous aspiration via the guiding catheter.
The clinical use of the phenox clot retriever in two successive patients is described. Case 1: In a 78-year-old patient with acute posterior circulation ischemia not eligible for intravenous or intraarterial thrombolysis, endovascular recanalization of the occluded left V4 segment was possible using the phenox clot retriever within a few minutes. Case 2: A 70-year-old patient presented after the sudden onset of a left upper extremity paresis 1 day after abdominal surgery. Angiography revealed a thromboembolic occlusion of two cortical branches of the right middle cerebral artery. The rolandic artery was recanalized by a single passage of the phenox clot retriever, with complete neurological recovery.
The phenox clot retriever, a flexible microfilament pattern, might be a useful supplement to the repertoire of currently available devices for endovascular intracranial thrombectomy.
描述一种用于各种大小颅内动脉快速血管内血栓切除术的新装置及其首次临床应用。
构建一种带有定向微丝的装置，该装置由一根芯线复合物组成，周围环绕着一层密集的垂直定向硬聚酰胺微丝栅栏（菲诺克斯血栓取出器）。该装置通过0.021英寸或0.027英寸的微导管引入目标血管，在血栓远端展开，并通过引导导管在持续抽吸的情况下缓慢回撤。
描述了菲诺克斯血栓取出器在连续两名患者中的临床应用。病例1：一名78岁急性后循环缺血患者，不符合静脉或动脉内溶栓条件，使用菲诺克斯血栓取出器在几分钟内实现了闭塞的左V4段血管内再通。病例2：一名70岁患者在腹部手术后1天突然出现左上肢无力。血管造影显示右大脑中动脉两个皮质分支血栓栓塞性闭塞。通过单次使用菲诺克斯血栓取出器使罗兰多动脉再通，患者神经功能完全恢复。
菲诺克斯血栓取出器这种灵活的微丝模式，可能是目前可用的血管内颅内血栓切除术器械库的有益补充。
