彩色多普勒超声在下肢深静脉血栓和动脉血栓栓塞中的应用

Application of Color Doppler Flow Imaging in Lower Extremities Deep Vein Thrombosis and Artery Embolism Patients

目的:探讨彩色多普勒超声在下肢深静脉血栓、下肢动脉栓塞性疾病中的应用。方法:入选本院2004-2006年5月36例患者的40条下肢动、静脉血管病变的二维图像及彩色多普勒血流特点进行观察和分析。结果:36例患者累及40条血管,深静脉血栓36条血管(36/40),占总血管条数90%(髂腘段7条、股段16条、股腘段3条、腘段10条);动脉栓塞4条血管(髂腘段2条、腘段2条),占总血管条数10%(4/40)。21条血管行血管造影证实,9条血管手术证实,10条血管与临床追踪的结果相符。结论:彩色多普勒超声诊断下肢深静脉血栓、下肢动脉栓塞具有简便、无创、可重复、准确而快速等特点,可作为临床上首选的检查方法。

Objective：To explore the application of color Doppler flow imaging（CDFI） in lower extremities deep vein thrombosis and artery embolism. Methods： Both two-dimensional and color Doppler ultrasound characteristics were observed and analyzed of 40 affected lower extremities arteries and deep veins in 36 patients treated between May 2004 and May 2005. Results： All these vessels comprised 36 with DVT（ 36/40 ,90% ;7 at the iliaco-popliteal part, 16 at the femoral part,3 at the femoral-popliteal part） and 4 with artery embolism（4/40,10% ;2 at the iliaco-popliteal part,2 at the popliteal part）. Findings in the affected vessels were confirmed by angiography （ n = 21 ）, surgery （ n = 9 ） and clinical follow-ups （n = 10）. Conclusion： CDFI provides an easy, reproducible, accurate and faster approach for diagnosis of lower extremities DVT and artery embolism, and therefore may be the first-choice diagnostic modality in these patients.
