摘要
目的评价影像学检查在肾细胞癌合并下腔静脉癌栓诊断中的价值。方法对１８例术前诊断肾细胞癌下腔静脉癌栓病人的影像学检查结果与手术病理结果进行对照分析。结果Ｂ超诊断肾细胞癌下腔静脉癌栓的准确度为４６２％、敏感度４４４％、特异度５０．０％；ＣＴ分别为７２２％、７１４％、７５．０％；彩超为７２７％、７５．０％、６６６％；联合两项以上影像检查则为８３３％、８５７％、７５．０％。结论ＣＴ与彩超对肾细胞癌下腔静脉癌栓的诊断准确度、敏感度、特异度相近，明显优于Ｂ超，两项或三项联合检查可明显提高本病诊断准确度、敏感度和特异度，并可替代创伤性大、不良反应多的下腔静脉造影。
bjective To evaluate the value of Bmode ultrasound (BUS),CT and color ultrasound in the diagnosis of renal cell carcinoma with cancer embolus in the inferior vena cava (IVC). MethodsBZEighteen cases,diagnosed as renal cell carcinoma with cancer embolus in the IVC by BUS,CT and color ultrasound preoperatively,were reviewed.Imaging findings and postoperative pathological reports were compared and analyzed.Results The accuracy,sensitivity and specificity of BUS are 46.2% ,44.4% and 50.0% respectively and those of CT 72.2%,71.4% and 75.0%.For color ultrasound these are 72.7%,75.0% and 66.6%.When the imaging procedures were used combinedly these are 83.3%,85.7% and 75.0%. ConclusionsBZThere is little difference between CT and color ultrasound in the diagnostic accuracy,sensitivity and specificity,and both have a great advantage over BUS.The combination of two or three of the imaging procedures will greatly enhance the accuracy,sensitivity and specificity,and can be used instead of venacavography which is invasive and has some adverse reactions.
