Objective:To evaluate the application of tr ansvaginal color Doppler flow imaging(TVCDFI)to the diagnosis of ilio-femoral v enous thrombosis.Methods:Forty normal adult subjects and twenty-one patie nts with deep venous thrombossis were studied by the 7.5MHz TVCDFI.The diamete r of the iliac vein,location of thrombosis,blood stream display and causes of th e disease were analysed comprehensively.Results:Compared to the conventional US,the iliac vein was cle arly displayed by TVCDFI with the rate of 100%.Thrombi were found at different l ocations of the ilio-femoral vein in all twenty-one patients.The blood stream signals became thinner or disappeared while the venous diameters were broadened or strictured.Conclusions:Combination of transvaginal and conventional ultr asonographies would be the first choice for the diagnosis of deep venous thromb osis in lower extremities in married females.%目的:探讨经阴道超声检测髂股静脉血栓形 成的应用价值。方法:应用7.5MHz经阴道彩色多普勒技术,检查了40例正常成人和21例深静 脉血栓患者的髂股静脉,对髂静脉内径、血栓部位、血流显示状况以及病因进行了综合分析 。结果:与常规超声比较,明显改善了髂静脉的显示条件,血管显示率达100% 。21例患者均在不同部位的髂股静脉内发现血栓斑块,静脉内径增宽或受压变窄,血流信号 变细或消失。结论:对已婚妇女下肢深静脉血栓的检查,常规超声加经阴道扫查应是临床 诊断的首选方法。
