下肢静脉曲张症的彩色多普勒血流显像特征及检测分析

目的:探讨和评价超声在下肢静脉曲张疾病中的显像特征、诊断价值及临床意义。方法:对36条经临床及X线造影确诊的患肢静脉血管进行探测,对引起下肢静脉曲张的不同病因、病损程度的超声特征进行分析,并与X线造影对照。结果:静脉瓣功能不全组、深静脉血栓形成组和单纯下肢静脉曲张组各自具备不同的超声特征,不同程度的下肢静脉曲张其2DE、CDFI显像及PW波形与测值亦不同。结论:与临床物理诊断及X线造影相比较,CDFI无创、简便、安全、可靠。对较大静脉的病变、机能状态的实时、动态观察更具优势。

Features detection and analysis of color Doppler flow imaging in lower extremity venous engorgement

Objective:To observe and evaluate the features,diagnostic value and clinical significance of ultrasonography in lower extremity with venous engorgement (LEVE).Methods:Thirty-two cases with LEVE diagnosed by angiography were ob-served by ultrasonography.We analyzed the different pathogenesis causing LEVE and ultrasonographic characteristics of LEVE in different degrees,and compared with angiography.Results:Characteristics of different ultrasonographic images were studied in those groups of venous valve in sufficiency,deep venous emboli and simple LEVE.Two-dimensional ultrasonography,CDFI and PW Doppler of LEVE in different degrees were different.Conclusions:Compared with physical diagnosis and angiography,CDFI as a non-invasive,simple and safe method,has more advantages in detection of the pathology and function of large ve-nous diseases.
