Abstract

To determine the causes and site(s) of nerve injury and to identify potential predictors of vocal fold paralysis (VFP) after carotid endarterectomy (CEA) by application of intraoperative neuromonitoring (IONM). A total of 68 CEA patients were enrolled in this study. A 3-step IONM procedure was designed to obtain vocal fold EMG data at V1 (just after identification of the vagus nerve [VN]), V2 (just before arteriotomy), and V3 (just before wound closure). We also performed IONM before/after hemostasis near the VN using bipolar forceps and before/after dissection of the VN. All patients underwent laryngoscopy to assess postoperative VFP. One patient showed loss of EMG signals between V2 and V3 and developed VFP that persisted for 11 months. The other 62 patients had no loss of EMG signals, but 2 patients had confirmed VFP for 1 month after CEA. There were no changes of EMG signal before and after VN dissection or hemostasis with bipolar forceps near the VN.

颈动脉内膜切除术中迷走神经的监测。

目的:探讨颈动脉内膜切除术(CEA)后声带麻痹(VFP)发生的原因和部位，并应用术中神经监测(IONM)技术探讨其潜在的预测因素。本研究共纳入68例CEA患者。设计了一个3步离子离子监测程序，以获得V1(刚刚识别迷走神经[VN])、V2(刚刚切开动脉之前)和V3(刚刚关闭伤口之前)的声带肌电图数据。我们还在VN附近使用双极钳止血前后和剥离VN前后进行了IONM。所有患者均行喉镜检查以评估术后VFP。1例患者在V2和V3之间出现肌电图信号丢失，并发VFP，持续11个月。其余62例未见肌电图信号丧失，2例CEA后1个月出现VFP。解剖和双极钳止血前后肌电图信号无明显变化。
