Symptomatic edema around a deep-brain stimulation (DBS) lead is a rare complication of DBS surgery. Although this phenomenon is not fully understood, clinical presentation of DBS lead edema can be severe enough to prompt treatment. There is a paucity of literature on the clinical course and treatment of DBS lead edema.
We present a 65-year-old man with Parkinson disease who developed unilateral DBS lead edema after bilateral subthalamic nucleus lead placement. Infectious, inflammatory, and ischemic causes were thoroughly investigated and ruled out. Clinical symptoms and radiographic changes all returned to normal with supportive care alone.
Lead edema is a rare complication after DBS surgery. It is important to recognize the benign clinical course of DBS lead edema to counsel patients and avoid unnecessary treatment such as hardware removal.
脑深部刺激（DBS）电极周围出现症状性水肿是DBS手术的一种罕见并发症。尽管这种现象尚未完全了解，但DBS电极水肿的临床表现可能严重到需要进行治疗。关于DBS电极水肿的临床病程和治疗的文献很少。
我们报告一名65岁的帕金森病男性，在双侧丘脑底核植入电极后出现单侧DBS电极水肿。对感染、炎症和缺血性病因进行了全面调查并排除。仅通过支持治疗，临床症状和影像学改变均恢复正常。
电极水肿是DBS手术后的罕见并发症。认识到DBS电极水肿的良性临床病程对于向患者提供咨询并避免不必要的治疗（如取出硬件）很重要。
