彩色多普勒超声诊断主动脉瘤的观察与分析

Diagonosis of aortic aneurysm by color Doppler ultrasound

目的 探讨超声诊断主动脉瘤的可靠性和准确性,评价其临床价值。方法 应用HP2500及TOSHIBA SSA-380A超声诊断仪,检查36例主动脉瘤患者,并将其部分超声检查结果与CT、核磁(MRI)、数字减影血管造影(DSA)及手术结果进行比较。结果 夹层动脉瘤与CT、MRI、DSA检查结果的符合率分别为86%、80%、89%;腹主动脉瘤与MRI、DSA及手术结果的符合率为100%。结论 彩色多普勒超声检查可发现有无主动脉瘤、动脉瘤的大小、范围、搏动和血流状态,对于夹层动脉瘤破裂口的观察、指导临床手术方案的选择有重要意义。

Objective To evaluate the value of ultrasound in diagnosis of aortic aneurysm . Methods Thirty six cases with aortic aneurysm were investigated by color Doppler ultrasound. The results were compared with computed tomography (CT), magnetic resonance imaging (MRI), digital subtraction angiography (DSA) and intraoperative findings. Results The coincidence of color Dopplor ultrasound with CT,MRI and DSA in diagnosis of aortic dissecting aneurysm were 86% .80% and 89%,respectively ;The coincidence of color Doppler ultrasound with MRI, DSA and intraoperative findings in diagnosis of abdominal aortic aneurysm were 100% ,100% . 100% .respectively. Conclusion The aortic aneurysm and its size, scope, throb and blood flow can be determined by color Doppler ultrasound. It has important significance for observating ruptured opening of aortic dissecting aneurysm and choosing operative plan.
