彩色多普勒超声在主动脉夹层动脉瘤诊断中的价值

Value of Color Doppler Ultrasound in Diagnosis of Dissecting Aortic Aneurysm

【目的】探讨彩色多普勒超声诊断主动脉夹层动脉瘤的临床价值。【方法】对采用彩色多普勒超声检查诊断的49例主动脉夹层动脉瘤患者进行回顾性总结分析。【结果】DebakeyⅠ型21例、DebakeyⅡ型11例、DebakeyⅢ型17例;术前正确诊断46例(93.88%),漏诊3例;经彩色多普勒超声诊断的主动脉夹层动脉瘤与CT、MRI、DSA检查诊断的符合率高。【结论】彩色多普勒超声检查对诊断主动脉夹层动脉瘤具有重要的临床价值。

[Objective] To estimate the value of color doppler ultrasound in the diagnosis of dissecting aor- tic aneurysm. [Methods] All 49 cases of dissecting aortic aneurysm were analyzed by color doppler ultrasonog- raphy. [Results] Forty six （93. 88%） cases with aortic dissecting aneurysm were accurately diagnosed on sonography, and 3 cases were misdiagnosed. Among 49 cases, type I was in 21 cases, type [I in 11 cases and type ]]] in 17 cases. The results of color doppler ultrasound were highly coincided with that of CT, MRI and DSA in diagnosis of dissecting aortic aneurysm. [Conclusion] Color doppler ultrasound is useful in diagnosis of dissecting aortic aneurysm.
