We report a case of femoral neuropathy caused by retractors used during operation. The patient (a 74-year-old woman) was scheduled for right hemicolectomy for cecum cancer, and anesthesia was maintained with nitrous oxide and sevoflurane in oxygen plus extradural anesthesia. After operation, the patient complained of hypesthesia in the anterolateral and medial area governed by the femoral nerve. Magnetic resonance imaging findings, were normal and the straight leg raising test was negative. After 2 months, the patient had completely recovered from the neurological symptoms. These manifestations were indicative of femoral neuropathy resulting from the pressure of large-bladed self-retraining retractors. It is important to include femoral neuropathy in the differential diagnosis of postoperative paralysis of the lower limb.
我们报告一例由手术中使用的牵开器引起的股神经病变。患者（74 岁女性）拟行右半结肠切除术治疗盲肠癌，麻醉维持采用氧化亚氮和七氟醚复合硬膜外麻醉。术后，患者诉股神经支配的前外侧和内侧区域感觉减退。磁共振成像结果正常，直腿抬高试验阴性。2 个月后，患者的神经症状完全恢复。这些表现提示股神经病变是由大叶片自约束牵开器的压力引起的。在术后下肢瘫痪的鉴别诊断中，股神经病应包括在内。
