为确定术前危险因素能否预测颈动脉切除术后卒中的不良预后,该试验将561名病人分为4组,术前无危险因素(组Ⅰ)。造影发现危险因素(组Ⅱ),内科有危险因素而造影无危险因素(组Ⅲ)和有神经外科危险因素(组Ⅳ)。其它伴随卒中的危险因素包括术间危险因素如使用动脉夹,输注葡萄糖液;外科并发症如颈动脉栓塞或结扎;内科并发症如缺氧和心 To determine whether preoperative risk factors predict a poor prognosis of stroke after carotid artery resection, 561 patients were divided into 4 groups, with no risk factors before surgery (Group I). Radiographic findings revealed risk factors (group II), medical risk factors without risk factors (group III) and risk factors for neurosurgery (group IV). Other risk factors associated with stroke include intraoperative risk factors such as the use of arterial clips, infusion of glucose solution, surgical complications such as carotid embolism or ligation, and medical complications such as hypoxia and heart
