目的:探讨产妇下肢静脉的超声声像图特点。方法:回顾性分析2010年1月~2014年6月在吉林省妇幼保健院行下肢静脉超声检查的产妇112例,对血管管径、管腔内情况、血栓位置、累及范围及二维、彩色多普勒、频谱多普勒超声表现进行观察,并与临床表现相互对照。结果:112例受检者中下肢静脉血栓54例共73条肢体,下肢静脉扩张伴血流缓慢者58例,其中肌间静脉39例、浅静脉19例。54例血栓均为急性期,累及部位以孤立性小腿深静脉血栓最多为27例,累及髂-股静脉及浅静脉者分别为3例、4例。超声表现为血栓段下肢静脉管腔内可见低回声充填,无血流信号或血流信号充盈缺损;其中症状明显者39例,无症状或症状轻微者15例。结论:彩色多普勒超声检查对产妇下肢静脉血栓的诊断及早期预防具有重要价值。
Objective: To investigate the characteristics of the sonography of lower extremity veins. Methods: A retrospective analysis was performed on 112 cases of lower extremity venous ultrasonography in Jilin Provincial Maternal and Child Health Hospital from January 2010 to June 2014. The data of blood vessel diameter, intraluminal conditions, thrombus position, involved area and two-dimensional, color Doppler, spectral Doppler ultrasound findings were observed and compared with the clinical manifestations. Results: Of the 112 subjects, 54 were involved in venous thrombosis of the lower extremities, with a total of 73 limbs, 58 cases of slow venous dilatation and slow blood flow, of which 39 were intramuscular and 19 were superficial veins. 54 cases of thrombosis were acute stage, involving parts of solitary leg deep vein thrombosis up to 27 cases involving the iliac - femoral vein and superficial vein were 3 cases, 4 cases. Ultrasound showed thrombosis of lower extremity venous lumen visible hypoechoic filling, no blood flow signal or filling of blood flow defect; of which 39 were obvious symptoms, asymptomatic or mild symptoms in 15 cases. Conclusion: Color Doppler ultrasound examination of lower extremity venous thrombosis in the diagnosis and early prevention of great value.
