| 目的 探讨术前仰卧位与俯卧位CT检查判断食管癌外侵主动脉的价值。方法 44例经病理学检查确诊的食管癌患者进行术前的CT检查及分析,用"夹角法"以及仰卧位与俯卧位相结合的"联合法"进行判断,所有患者均有两种体位的CT检查及分析并与手术及术后病理学结果相对比。结果 按照"夹角法",本组44例病人主动脉受侵的敏感性,特异性及准确性分别为76.92%、70.97%及72.73%;按照"联合法",主动脉受侵的敏感性、特异性及准确性分别为92.31%、90.32%及90.91%;(经χ2检验,两种方法相比,特异性与准确性P均<0.05)。当俯卧位CT扫描时,若主动脉受侵,食管肿物与主动脉间可出现"融合征"。结论 "联合法"判断食管癌外侵主动脉价值大;在俯卧位CT检查时,"融合征"有助于判断主动脉受侵。 |

| Objective To explore the value of preoperative esophageal carcinoma with supine and prone CT scans to detect aortic invasion. Methods 44 cases with histologic diagnosis of esophageal carcinoma underwent preoperative CT scans examination and analyse,with the "angle method " and "combined method", and they were compared preoperative CT scans with operations and postoperative pathohistologic findings. Results According to "the angle method" criterion,sensitivity,specificity and accuracy of the 44 cases were 76.92%,70.97%,72.73%, respectively;according to the criterion of "combined method", sensitivity ,specificity and accuracy were 92.31%,90.32%and 90.91%,respectively.when esophageal carcinoma invasion aorta the "fusing sign" can occur between esophageal and aorta in the prone CT scans. Conclusion The value of "combined method " to detect aortic invasion is high; (specificity and accuracy,P<0.05). "Fusing sign" can help detect esophageal carcinoma invasion aorta in the prone CT scans. |
