Axillary Impella devices are increasingly employed for long-term support of patients with systolic heart failure and shock. Axillary access allows for awake support and ambulation, which carries an inherent risk of disconnection or malposition. We report a series of two cases where device replacement due to dysfunction and malposition can be completed safely through the original axillary graft using axillary graft thrombectomy, given that the clot burden could be a major source of morbidity to the patient.
腋动脉置入式Impella装置越来越多地用于对收缩性心力衰竭和休克患者的长期支持。经腋动脉置入可实现清醒状态下的支持和下床活动，但存在装置断开连接或位置不当的固有风险。我们报告了两例病例，鉴于血栓负荷可能是患者发病的主要原因，通过腋动脉移植物血栓切除术，可经原腋动脉移植物安全完成因功能障碍和位置不当而进行的装置更换。
