目的探讨术前CT检查“夹角法”+“厚度法”判断食管癌外侵主动脉的价值。方法65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”+“厚度法”相结合的方法进行判断,所有患者均有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”与“厚度法”相结合的判别方法,本组65例病人主动脉受侵的敏感性、特异性及准确性分别为87.50%、87.76%及87.69%。结论“夹角法”+“厚度法”判断食管癌外侵主动脉价值较大。
Objective To evaluate the value of “angle method” + “thickness method” in preoperative CT examination to detect the invasion of esophageal carcinoma to the aorta. Methods Sixty-five patients with pathologically confirmed esophageal cancer underwent preoperative CT examination and analysis with “angle method” + “thickness method”. All patients had CT examination and analysis and were compared with surgery And postoperative pathological results relative ratio. Results According to the method of “angle method” and “thickness method”, the sensitivity, specificity and accuracy of aortic invasion in 65 patients were 87.50%, 87.76% and 87.69% respectively. Conclusion “Angle method” + “thickness method” to determine the value of esophageal cancer invasion of aorta larger.
