【摘要】：目的探讨胎儿上纵隔左右锁骨下动脉切面及其应用价值。方法将胎儿脊柱显示至3点钟或9点钟,在胎儿三血管气管切面的基础上,向胎儿头侧稍稍偏转探头,再叠加彩色多普勒血流成像,将彩色标尺调低,并将彩色增益适当调高,即可以显示上纵隔左右锁骨下动脉切面。结果 100例正常胎儿上纵隔左右锁骨下动脉切面的显示率为100%,显示内容包括:(1)左、右锁骨下动脉走行较弯曲,呈"弯弓状"分别走向左、右肩;(2)右锁骨下动脉在气管的前方走向右肩;(3)右锁骨下动脉与右无名静脉之间的间隙较小;(4)左、右无名静脉走行平直,汇入右上腔静脉。2例迷走右锁骨下动脉表现:右锁骨下动脉走行平直,在气管的后方走向右肩;右锁骨下动脉与右无名静脉之间的间隙加大。结论胎儿上纵隔左右锁骨下动脉切面对显示左、右锁骨下动脉及其与气管的位置关系具有重要的作用,在产前常规探查有助于提高迷走右锁骨下动脉的检出率。
[Abstract]:Objective to explore the sectional plane of left and right subclavian artery of upper mediastinum of fetus and its application value. Methods the fetal spine was displayed to 03:00 or 09:00, and on the basis of the tracheostomy of fetal three vessels, the probe was slightly deflected to the head side of the fetus. Then the color Doppler flow imaging is superimposed, the color scale is lowered, and the color gain is adjusted up appropriately. Results in 100 normal fetuses, the display rate of the left and right subclavian arteries of the superior mediastinum was 100, including 1: 1) left. The right subclavian artery was more curved, showing a "curved arch" toward the left and right shoulder, respectively. (2) the right subclavian artery moves to the right shoulder in front of the trachea; 3) the space between the right subclavian artery and the right unnamed vein was smaller. 4) the left and right unnamed veins were straight, and the right subclavian artery was obliterated into the right superior vena cava in .2 cases: the right subclavian artery was straight, and it was moving to the right shoulder at the rear of the trachea; The space between right subclavian artery and right unnamed vein is enlarged. Conclusion the left and right subclavian artery of the left and right subclavian artery and its relationship with the trachea play an important role in the left and right subclavian artery of the fetal superior mediastinum. Routine antenatal exploration is helpful to improve the detection rate of the right subclavian artery (right subclavian artery).

【正文快照】： 迷走右锁骨下动脉是产前超声筛查胎儿21-三体综合征的指标之一,常在三血管气管切面上被显示出来[1-3]。然而,由于迷走右锁骨下动脉内径细小、血流速度慢、位置不定,在三血管气管切面上容易漏诊[4],因此直接显示右锁骨下动脉的意义重大。本文旨在介绍胎儿上纵隔左右锁骨下动
