彩色多普勒超声诊断医源损伤性假性动脉瘤的价值

目的：探讨彩色多普勒超声在诊断冠状动脉造影术后引发的医源损伤性假性动脉瘤的临床价值。方法：经股动脉穿刺,行冠状动脉造影术而发生的股动脉假性动脉瘤共39例,所有患者都采用高频彩色多普勒诊断仪,对动脉瘤的二维超声图像、彩色多普勒图像及脉冲多普勒图像进行分析。结果：39例假性动脉瘤患者在穿刺部位动脉的一侧均显示一搏动性无回声区或混合性低回声区;彩色多普勒显示无回声区内呈涡流或旋转样血流信号,表现为一半红色一半蓝色;脉冲多普勒显示典型的双期双向频谱。39例假性动脉瘤彩色多普勒超声诊断完全明确。其中32例在彩色多普勒超声监控下行人工加压包扎修复。7例经血管外科手术修补治疗。结论：彩色多普勒超声在诊断冠状动脉造影术后造成的医源损伤性假性动脉瘤,在观察动脉瘤的大小、形态、瘤体的结构,判断来源动脉破口定位上准确、简便、无创,且可在超声引导下行安全无创治疗,可作为该病诊断及治疗的首选方法。

The Value of Color Doppler Flow Imaging in the Diagnosis of Iatrogenic Damaging Pseudoaneurysm

Objective：To investigate the clinical value of Color Doppler Flow Imageing（CDFI） in the diagnosis of iatrogenic damaging pseudoaneurysm caused by femoral artery centesis.Methods：Thirty-nine patients with femoral pseudoaneurysm induced by femoral artery centesis were involved in the study.They were examined by high frequency ultrasound to compare and analyze their characteristic of two dimensional ultrasonography,color Doppler image and pulse Doppler spectrum.Results：The pulsant anechoic area or a mixed low level echo area in the site of the centesis artery was typical feature of 39 pseudoaneurysm.Vortexing or rotating blood flow signal in the anechoic area was shown by the CDFI.Pulse Doppler show a typical biperiodic and bidirectional frequency spectrum.Thirty-two of 39 cases were treated by CDFI guided compression and 7 cases treated by vascular surgery.Conclusion：CDFI provides an accurate,simple,convenient and non-invasive method in the diagnosis of pseudoaneurysm.
