The authors present the case of a 78-year-old right-handed female with a past medical history of Parkinson's disease, treated with implantation of a left-sided subthalamic nucleus St. Jude Medical Infinity® (Abbott Medical, Austin, TX) deep brain stimulator, who presented with lead-associated discomfort, or "bowstringing". Further investigation by chest X-ray revealed an extensive case of distal lead coiling. However, it was surprising that, despite the extensive coiling, the lead stayed intact without hardware failure as proven by patient remaining asymptomatic from her Parkinson's disease and intraoperative impedance testing demonstrating normal results. After revision surgery, the patient remained asymptomatic. Due to paucity of cases of this disease in the literature, specific predictive risk factors are not known, but certain patient characteristics may help take precautions.
作者介绍了一名78岁右利手女性的病例，该患者有帕金森病病史，接受了左侧丘脑底核圣犹达医疗Infinity®（雅培医疗，德克萨斯州奥斯汀）深部脑刺激器植入治疗，出现了与电极相关的不适，即“弓弦样”现象。胸部X光进一步检查发现电极远端广泛盘绕。然而，令人惊讶的是，尽管盘绕广泛，但电极仍保持完整，未发生硬件故障，这通过患者帕金森病无症状以及术中阻抗测试结果正常得到证实。翻修手术后，患者仍无症状。由于文献中该疾病的病例较少，具体的预测风险因素尚不清楚，但某些患者特征可能有助于采取预防措施。
