摘要
胸主动脉是动脉粥样硬化病变最常见的部位之一。我们使用经食管超声心动图对连续137例患者(59 +/- 10岁)的胸主动脉动脉粥样硬化病变进行了评估。研究人群包括60名冠状动脉疾病患者(CAD), 36名高血压患者(HT), 28名高胆固醇血症患者(HC,总胆固醇大于或等于230 mg/dl), 8名夹层动脉瘤患者,9名真动脉瘤患者和2名主动脉炎综合征患者。我们使用单个横向扫描平面探头,超声频率为5 MHz。除升主动脉上段外,全胸主动脉均可获得满意的超声图像。我们将动脉粥样硬化病变定义为内膜回声密度增高、斑块突出、溃疡或动脉瘤。137例患者中有71例(52%)出现动脉粥样硬化病变。动脉粥样硬化病变在HT(72%)、HC(57%)和CAD(57%)患者中发生率高,而在没有HT、HC、CAD或主动脉瘤的患者中,动脉粥样硬化病变发生率低(15%)。年龄大于或等于60岁的患者更常观察到动脉粥样硬化病变(69% vs 34%, p < 0.001)。在HT或HC患者中,甚至在60岁以下的患者中也经常观察到动脉粥样硬化病变(HT: 58%, HC: 53%)。我们认为HT、HC和年龄是胸主动脉动脉粥样硬化过程的重要危险因素,经食管超声心动图是详细评估胸主动脉动脉粥样硬化病变的有效方法。
[Estimation of atherosclerotic lesions in the thoracic aorta by transesophageal echocardiography].
The thoracic aorta is one of the portions frequently involved with atherosclerotic lesions. We estimated atherosclerotic lesions in the thoracic aorta in consecutive 137 patients (59 +/- 10 years old) using transesophageal echocardiography. The study population consisted of 60 with coronary artery disease (CAD), 36 with hypertension (HT), 28 with hypercholesterolemia (HC, total cholesterol greater than or equal to 230 mg/dl), eight with dissecting aneurysm, nine with true aneurysm and two with aortitis syndrome. We used a single transverse scan-plane probe with ultrasound frequency of 5 MHz. We could obtain satisfactory echograms of whole thoracic aorta except upper portion of the ascending aorta. We defined atherosclerotic lesions as an increased echo-density of the intima, protruded plaque, ulceration or aneurysm. Atherosclerotic lesions were observed in 71 of 137 patients (52%). High incidence of the atherosclerotic lesions was seen in patients with HT (72%), HC (57%) and CAD (57%), whereas incidence of atherosclerotic lesions was low (15%) in patients without HT, HC, CAD or aortic aneurysm. Atherosclerotic lesions were observed more frequently in patients aged greater than or equal to 60 years (69% vs 34%, p less than 0.001). In patients with HT or HC, atherosclerotic lesions were frequently observed even in patients younger than 60 years old (HT: 58%, HC: 53%). We concluded that HT, HC and aging were important risk factors for the atherosclerotic process in the thoracic aorta, and transesophageal echocardiography was a useful approach for the detailed estimation of atherosclerotic lesions in the thoracic aorta.
