摘要
目的探讨彩色多普勒超声在诊断以肢体功能障碍为主要表现的主动脉夹层中的应用价值。方法选择2014年3月~2015年3月于我院经CT血管造影证实的61例主动脉夹层患者（其中11例以肢体功能障碍为主要表现）,均进行彩色多普勒超声检查并分析其影像学特点。结果 61例患者中,彩色多普勒超声检出51例,漏诊10例,检出率为83.6%。11例以肢体功能障碍为主诉的患者均为Debakey I型,其中7例未见明显动脉硬化,4例可见轻度动脉硬化,患者动脉远端均呈现静脉样频谱改变。结论彩色多普勒超声具有操作方便、实时、安全、无创、便于转移等特点,可作为以肢体功能障碍为主要表现的主动脉夹层的初筛手段,同时对治疗方案的选择及疗效评价具有重要意义。
Objective To analyze the application value of color Doppler ultrasound in the diagnosis of aortic dissection with limb dysfunction as the main clinical manifestation. Methods Select 61 cases that were diagnosed with aortic dissection confirmed by CT angiography from March 2014 to March 2015（among which 11 cases showed signs and symptoms of limb dysfunction as the main clinical manifestation and chief complaint）. All the 61 cases underwent color Doppler ultrasonography. The imaging characteristics of each case were retrospectively analyzed. Results Among the 61 patients, aortic dissection was detected in 51 cases by color Doppler ultrasonography. The aortic dissection in the rest 10 cases was not detected. The detection rate is 83.6%. The 11 cases with limb dysfunction as the chief complaint can be classified as De Bakey I, among which 7 cases show no obvious signs of arthrosclerosis, 4 cases show signs of mild arthrosclerosis. All the patients showed changes in venous sample frequency at distal arteries. Conclusion Color Doppler ultrasound is easy to operate and transfer. It can provide real-time imaging in a safe and non-invasive manner. It can be used as the preliminary screening method for aortic dissection with limb dysfunction as the main clinical manifestation. Meanwhile it is of great significance in choosing care plans as well as in evaluating the clinical effects.
