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。
【摘要】 目的 探讨超声在诊断颈部转移性与淋巴瘤性淋巴结中的应用价值。 方法 2007年1月-2008年12月对经病理证实的102例患者120个颈部淋巴结，应用二维超声、能量多普勒显像（PDI）分为两组:转移性淋巴结68个，淋巴瘤性淋巴结52个。对淋巴结长短比（L/S）、结构及血流分布状态进行分析。 结果 两组淋巴结门消失、局部液化灶、中央血流率比较差异有统计学意义（Plt;0.05），两组出现淋巴结形态不规则、皮质回声减低、淋巴门型血流、周围型血流率比较差异有统计学意义（Plt;0.05）。两组的L/S≤2淋巴结无统计学差异（Pgt;0.05）。 结论 超声检查对颈部转移性淋巴结与淋巴瘤性淋巴结的鉴别诊断有较高价值。【Abstract】 Objective To explore the application value of the ultrasound in diagnosis of metastatic and lymphoma lymph nodes of the neck. Methods From January 2007 to December 2008, 120 neck lymph nodes of 102 patients confirmed by pathology were divided into two groups, including 68 metastatic lymph nodes and 52 lymphoma lymph nodes. The reports of two groups were performed using two-dimensional ultrasonography and power Doppler imaging (PDI). The long-short axis ratio (L/S), structure, blood flow pattern of lymph nodes were studied. Results The rate of the lymph door disappearance, inner liquefacient position and central blood stream in two groups had statistical difference (Plt;0.05). The rate of irregular form, diminution of cortical resonance, blood stream of lymph door and peripheral flow in two groups had statistical difference (Plt;0.05), but the difference of their L/S≤2 had no statistical significance (Pgt;0.05). Conclusion The ultrasonography is a valuable method for diagnosing between neck metastatic nodes and lymphoma lymph nodes.
