利用CT胸部扫描对支气管肺癌病人进行纵隔病变的检查,是近来采用的一种有效技术.CT扫描能够对直径小到3～4mm的淋巴进行影象诊断.该文报导了148例病人术前均经CT扫描估价,结果有146例病人病变得到切除.分析时把直径≥1.5cm的淋巴结列为异常.所有经CT检查发现的异常淋巴结均通过纵隔镜检查、前纵隔探查或开胸探视进行验证估价.而CT检查淋巴结阴性病人不经以上检查就可直接进行手术.手术病人分为两组.Ⅰ组(51例),术中没有进行常规纵隔探查,Ⅱ组(后97例),每个病人均常规进行纵隔探查,对淋巴结均有组织学检查资料,把CT扫描的结果和临床资料进行比较,结果CT扫描对检查纵隔病变敏感性、特异性和准确性分别为80%、90%和 The use of CT chest scans to examine mediastinal lesions in patients with bronchial lung cancer is an effective technique that has recently been used. CT scans can be used to diagnose lymph nodes with diameters as small as 3 to 4 mm. This article reports 148 patients who were preoperative Estimated by CT scan, 146 patients were resected. Lymph nodes with a diameter of ≥ 1.5 cm were classified as abnormal during analysis. All abnormal lymph nodes detected by CT were verified by mediastinoscopy, anterior mediastinal probing, or thoracotomy access. Evaluation. CT examination of lymph node negative patients can be performed directly without the above examination. Surgical patients are divided into two groups. Group I (51 cases), no routine mediastinal exploration during the operation, group II (post-97 cases), each All patients underwent routine mediastinal probing and had histological examinations of lymph nodes. The CT scans were compared with clinical data. The results showed that the sensitivity, specificity, and accuracy of CT scans were 80%, 90%, and 90%, respectively.
