| 中文摘要: |
| 本组主动脉病变60例(男40例, 女20例), 年龄19～65岁, 平均年龄41岁。其中单纯主动脉瘤17例, 病变局限于升主动脉, 其内未见撕裂的内膜光带反射。主动脉夹层动脉瘤37例(经手术证实5例, 血管造影证实3例, 磁共振证实2例), DeBakeyⅠ型6例, DeBakeyⅡ型21例, DeBakeyⅢ型10例, 均可见撕裂的主动脉壁内膜反射, 5例患者假腔内有血栓形成。彩色多普勒显示真腔内血流速度较快, 假腔内血流速度较慢。主动脉假性动脉瘤1例(手术证实), 可显示主动脉壁的破裂口及破裂口外围的附属腔及破裂口处的血流情况。降主动脉缩窄5例。4例为降主动脉起始部缩窄。经食道超声心动图能清楚地显示主动脉病变的性质、血流情况和累及的范围, 在观察主动脉病变方面具有重要的价值。 |
| 英文摘要: |
| The diagnostic value of transesophageal echocardiography(TEE) in assessment of patients with aortic disease was studied. TEE was performed in 60 patients with aortic disease. In 17patiests with true aortic aneurysm, ascending aorta was dilated and there was no intimal flap in it. In 37 cases with aortic dessection (5cases were confirmed by surgery, 3 by angiography, 2 by magnetic resonance imaging), DeBakey type classification could be identified in all patients (DeBakey type Ⅰ: 6 ; type Ⅱ: 21 ; type Ⅲ : 10). TEE demonstrated intimal flap in all patients. The entry of aortic dissection could be identified in 31 patients. Thrombus were detected in false lumen in 5 cases. Color Doppler could detect the flow in the true and false lumen and the communications between the true and false lumen. In 5 patients with aortic coractation, the narrowing arear were occurred at the junction of the aortic arch and the descending aorta in 4 patients. TEE provides ultrasonic access to the heart and aorta from esophagus without restriction by lung tissue or chest wall.TEE is very important in detecting the aortic diseases. |
