摘要
目的 探讨创伤性子宫动静脉瘘 (AVM )的灰阶超声、彩色多普勒超声和盆腔血管造影的特征。方法 7例创伤性AVM患者均行超声检查、血管造影。记录各病例的收缩期峰值血流速度 (PSV)和阻力指数 (RI)。结果 子宫动静脉瘘在二维声像图上没有特异性。彩色多普勒血流显像病灶显示特征性的丰富血流。多普勒频谱表现为高速低阻的特点 ,PSV 3 6～ 10 2cm/s ,RI 0 .3 0～ 0 .43。盆腔血管造影可显示动静脉瘘形成处的血管。结论 彩色多普勒超声是无创性诊断创伤性AVM的可靠方法。
Objective To describe the gray scale and color Doppler sonography and angiography features of traumatic uterine arteriovenous malformation (AVM).Methods Seven cases of traumatic AVM underwent gray scale and color Doppler sonography and angiography. The peak systolic velocity (PSV) and resistant index (RI) were recorded. Results At gray scale, traumatic uterine AVMs were nonspecific. On color Doppler flow imaging, intensely colored patterns were depicted. Spectral Doppler revealed low resistance (RI 0.30 ～ 0.43 ) and high flow (PSV 36～102 cm/s). Angiography revealed the vessels of the uterine AVM.Conclusions Color Doppler flow imaging features should allow noninvasive diagnosis of traumatic uterine AVM.
