彩色多普勒超声对动脉瘤的诊断价值

The value of color Doppler ultrasonography in diagnosing aneurysm

采用多普勒超声检查动脉瘤５９例，５４例获血管造影和／或手术证实。其中真性动脉瘤３４例（６３％），假性动脉瘤１８例（３３％），浅表先天性动静脉瘤２例（４％）；合并夹层剥离８例；超声误诊１例，诊断符合率９８％。

Using Doppler ultrasound, We detected 59 patients with aneurysm, 54 cases were confirmed by angiography or operation or both. Among them, 33 cases(63%) showed true aneurysm, 18 cases (33%) pseudoaneurysm, and 2 cases (4%) superficial congenital arteriovenous aneurysm. Eight cases were associated with dissected stripping. One case was falsely diagnosed by ultrasonography. The diagnostic accuracy was 98%. The results suggest that color Doppler ultrasonography is useful in detecting aneurysm.
