To assess the diagnostic performance of two-dimensional echocardiography in the diagnosis of dissecting aneurysm, 12 patients (7 women and 5 men with a mean age of 51 years) with clinically suspected dissecting aneurysm were investigated. The diagnosis was confirmed by angiography or operation or autopsy in all patients. Eight had a dissecting aneurysm and the remaining 4 had a saccular aneurysm. The intimal flap echo was observed in 7 of the 8 patients with dissecting aneurysm. The intimal flap motion in these patients showed a fluctuating motion. The site or spread of this echo corresponded well with the anatomical lesion. On the other hand, an intra-aortic abnormal linear echo was observed in three of the 4 patients with saccular aneurysm. However, this linear echo showed little motion. The sensitivity, specificity and predictive value of the intimal flap echo in association with its fluctuating motion in the diagnosis of dissecting aneurysm were all 100%, although the efficiency remained at 69%. It was concluded that the real-time two-dimensional echogram is useful in the diagnosis of acute dissecting aneurysm.
为评估二维超声心动图对夹层动脉瘤的诊断效能，对12例临床怀疑为夹层动脉瘤的患者（7例女性，5例男性，平均年龄51岁）进行了研究。所有患者均经血管造影、手术或尸检确诊。8例为夹层动脉瘤，其余4例为囊状动脉瘤。8例夹层动脉瘤患者中有7例观察到内膜瓣回声。这些患者的内膜瓣运动呈波动状。该回声的部位或范围与解剖病变高度相符。另一方面，4例囊状动脉瘤患者中有3例观察到主动脉内异常线性回声。然而，该线性回声几乎无运动。内膜瓣回声及其波动运动对夹层动脉瘤诊断的敏感性、特异性和预测价值均为100%，尽管诊断效率仍为69%。结论是实时二维超声心动图对急性夹层动脉瘤的诊断有帮助。
