目的探讨急诊经胸超声心动图诊断主动脉夹层动脉瘤的临床应用价值。方法应用HP5500及Vivid7彩色超声诊断仪,诊断主动脉夹层动脉瘤患者28例,并将其超声检查结果与CT、MRI、DSA、介入及外科手术结果进行比较。结果主动脉夹层动脉瘤经胸超声心动图与CI、MRI、DSA及手术结果的符合率在98%以上(P>0.05)。结论急诊经胸超声心动图诊断主动脉夹层动脉瘤可靠、准确,能清楚鉴别真腔与假腔,显示内膜破口并分型,对指导临床选择最佳治疗方案起着重要意义。
Objective To investigate the clinical value of emergency transthoracic echocardiography in the diagnosis of aortic dissection aneurysm. Methods 28 cases of aortic dissecting aneurysm were diagnosed by HP5500 and Vivid7 color ultrasonic diagnostic apparatus. The results of ultrasonic examination were compared with CT, MRI, DSA, interventional and surgical results. Results The coincidence rate of transthoracic echocardiography and CI, MRI, DSA and surgical findings of aortic dissecting aneurysms was over 98% (P> 0.05). Conclusions Emergency transthoracic echocardiography is a reliable and accurate method for the diagnosis of aortic dissection aneurysms. It can distinguish true and false cavities clearly, and it can display endometrial rupture and classification. It plays an important role in guiding clinical choice of optimal treatment.
