彩色多普勒超声对腹主动脉瘤诊断与分型价值的探讨

目的：探讨彩色多普勒超声在诊断腹主动脉瘤中的应用价值。方法：回顾性分析近6年来彩色多普勒超声首先检出的腹主动脉瘤21例，并与CT强化扫描检查对照。全部病例均经X线血管造影证实。结果：超声与CT对腹主动脉瘤的敏感性、特异性强，诊断结果可靠，但对夹层动脉瘤破裂口、真假腔问剥脱的内膜及假腔内血栓的显示等方面彩色多普勒超声比CT更为实时、便捷。根据腹主动脉瘤的声像图表现，我们将其分为：无回声型、混合回声型和膜状两腔回声型三类。结论：彩色多普勒超声对腹主动脉瘤的诊断与分型具有重要的临床诊断价值。

Application of colour Doppler flow imaging in diagnosis of abdominal aortic aneurysm

Objective:To evaluate the colour Doppler flow imaging (CDFI) in the diagnosis of abdominal aortic aneurysm.Methods:21 cases of abdominal aneurysms diagnosed firstly by color Doppler ultrasonograhy were analysed retrospectively and compared with contrast CT scanning in the last six years.Results:21 cases of abdominal aneurysm were finally confirmed by X ray angiography,ultrasonography and contrast CT scanning have high sensitivity and specificity.Color Doppler ultrasonoqraphy is simpler and realtime than CT scanning in the diagnosis of rapure orifice,true and false lumen and thrombosis in the false lumen and aneurysm.There are many advantages which is better than X ray angiography.According to the ultrasonic imagings of abdominal aneurysm it is classified as non-echogenic ,mixed-echogenic and double-lumen echogenic type.Conclusion:Color Doppler ultrasonography has significant clinical significane in the diagnosis and classification of abdominal aneurysm.
