The recurrence or exacerbation of phantom limb pain (PLP) induced by spinal anesthesia in patients with amputated limbs is rare, but it can occur in any amputee. A 76-year-old woman with an amputated right knee underwent three left knee surgeries with spinal anesthesia over a period of 6 months. She did not experience PLP in the previous two surgeries but experienced the recurrence of severe PLP after the third surgery for the left knee amputation. It is believed that this third operation caused the patient to experience even more severe psychological stress than the previous two operations. Regional blocks can induce PLP in amputees. In addition, PLP can be triggered and exacerbated by psychological factors. Therefore, we suggest that physicians check the patient's psychological state and provide adequate mental stability when performing surgeries with spinal anesthesia in amputated patients.
残肢断肢后脊髓麻醉引起的幻肢痛（PLP）复发或加重较为罕见，但可发生于任何截肢患者。一名 76 岁女性因右膝截肢，在 6 个月期间接受了 3 次左膝手术的脊髓麻醉。前两次手术中她并未经历幻肢痛，但在第三次左膝截肢手术后出现了严重的幻肢痛复发。据信，第三次手术使患者经历了比前两次手术更严重的心理压力。区域阻滞可在截肢患者中引起幻肢痛。此外，PLP 可由心理因素引发和加重。因此，我们建议医生在为截肢患者行脊髓麻醉手术时检查患者的心理状态并提供充分的精神稳定。
