摘　　要：目的:探讨常规超声、彩色多普勒超声、超声造影及术中超声在肾癌合并下腔静脉癌栓的诊断及临床分型中的应用价值。方法:对7例肾癌合并下腔静脉癌栓的患者进行常规超声、彩色多普勒超声检查,其中3例行超声造影检查,3例行术中超声检查。所有病例均经手术及病理证实。结果:所有下腔静脉栓子均为癌栓,癌栓分型为Ⅱ型4例,Ⅲ型2例,Ⅳ型1例。结论:超声技术对肾癌合并下腔静脉癌栓的诊断与鉴别诊断具有重要价值,并且能够脉对癌栓进行准确分型,对临床手术治疗及预后判断具有指导性意义。Objective：To discuss the value of conventional ultrasonography,color Doppler ultrasonography,contrast-enhanced ultrasonography（CEUS） and intraoperative ultrasonography in the differential diagnosis and clinical typing of renal cell carcinoma complicated with inferior vena cava（IVC） tumor thrombus.Methods：7 cases having renal cell carcinoma complicated with inferior vena cava（IVC） tumor thrombus underwent conventional and color Doppler ultrasonography,of which,3 cases underwent CEUS and 3 cases underwent intraoperative ultrasonography.All of the cases were confirmed by surgery and pathology.Results：All of the IVC thrombi were tumor thrombi including type Ⅱ（4 cases）,type Ⅲ（2 cases）,type Ⅳ（1 case）.Conclusion：Ultrasonography is helpful in the diagnosis and differential diagnosis of renal cell carcinoma complicated with inferior vena cava tumor thrombus as well as their accurate classification,which is significant in the guidance of surgery and prediction of prognosis.
