Recently, the utilization of Impella 5.5, especially in the axillary position, has increased exponentially. The device provides excellent hemodynamic support for patients in cardiogenic shock, as a bridge to recover, transplant, or durable left ventricular device. However, small size arteries remain its main limitation. With a maximum diameter of 19 Fr (6.33 mm), the recommended artery size needed for implantation is 7 mm. In this case, we discuss the successful implantation and removal of the Impella 5.5 device into a patient, with a subclavian artery diameter of 4 mm, whose other short- and mid-term options for mechanical circulatory support were limited.
最近，Impella 5.5的应用，尤其是在腋部位置的应用呈指数级增长。该装置为心源性休克患者提供了出色的血流动力学支持，作为恢复、移植或持久左心室装置的桥梁。然而，小尺寸动脉仍然是其主要限制。其最大直径为19 Fr（6.33毫米），植入所需的推荐动脉尺寸为7毫米。在这种情况下，我们讨论了将Impella 5.5装置成功植入并取出一名锁骨下动脉直径为4毫米的患者的过程，该患者机械循环支持的其他短期和中期选择有限。
