目的 :探讨能量多普勒血流显像对诊断主动脉窦瘤的临床价值。方法 :用二维超声、彩色多普勒血流显像、能量多普勒血流显像对 9例主动脉窦瘤进行检查 ,部分患者用 5 %碳酸氢钠加维生素 B6行右心声学造影。结果 :本组主动脉窦瘤的超声诊断结论与手术或其它医学影像检查的符合率达 10 0 %。能量多普勒血流显像观察主动脉窦瘤的形态、壁的回声完整性及破裂口的大小和部位较为清晰。结论 :能量多普勒血流显像对诊断主动脉瘤有一定的临床价值
Objective : To explore the clinical value of power Doppler flow imaging in the diagnosis of aortic sinus aneurysm. METHODS: Nine cases of aortic sinus aneurysm were examined by two-dimensional ultrasound, color Doppler flow imaging, and power Doppler flow imaging. Some patients underwent right heart sonography with 5% sodium bicarbonate plus vitamin B6. . RESULTS: The coincidence rate of ultrasound diagnosis of aortic sinus aneurysm with surgical or other medical imaging was 100%. The power Doppler flow imaging was used to observe the morphology of the aortic sinus aneurysm, the echogenicity of the wall, and the size and location of the rupture opening. Conclusion: Power Doppler flow imaging has certain clinical value in the diagnosis of aortic aneurysm
