超声诊断子宫动静脉瘘

目的探讨子宫动静脉瘘的超声表现及鉴别诊断。方法回顾性分析12例子宫动静脉瘘的超声表现,并与子宫动脉造影相对照。结果子宫动静脉瘘超声表现为近内膜处子宫肌壁或剖宫产切口处肌壁回声不均匀,可见不规则无回声区,典型者呈＂蜂窝样＂改变,CDFI显示局部区域血流异常丰富,呈＂湖泊样＂或＂五彩镶嵌样＂改变,频谱多普勒表现为高速低阻的血流频谱。子宫动脉造影结果与超声检查结果一致。结论超声结合子宫动脉造影有助于确诊子宫动静脉瘘。

Ultrasonic diagnosis of uterine arteriovenous fistula

Objective To investigate the value of ultrasound in diagnosis and differential diagnosis of uterine arteriovenous fistula (UAF). Methods Ultrasound results of 12 patients with UAF were analyzed retrospectively, and were compared with uterine artery angiography. Results UAF showed uneven echo signals of uterine muscle wall near endometrium or cesarean section incision and irregular echo-free zone on ultrasonographies, the typical case of which displayed "honeycomb-like" change. Color Doppler ultrasound showed rich blood flow in local area and lake-like or multicolored mosaic change. Spectral Doppler waveform shape was characterized as high-speed low resistance. The ultrasonographic results of UAF were consistent with those of uterine artery angiography. Conclusion Ultrasonography combined with uterine artery angiography contributes to the diagnosis of UAF.
