经食管二维彩色Doppler超声心动图评价法乐氏四联症

Transesophageal Two-dimensional Echocardiography with Doppler Colour Flow Imaging for Evaluating Tetralogy of Fallot

用单平面经食管二维彩色Doppler超声心动图诊断评价28例法乐氏四联症的临床价值。其中清醒病人19例,手术病人9例。男18例,女10例,最小年龄12岁,最小体重36kg。结果显示:与胸前超声心动图相比,经食管超声心动图能更清楚显示法乐氏四联症肺动脉主干、分叉部、几乎整个右肺动脉、左肺动脉近端及房间隔病变,而显示右室流出道漏斗部病变不如胸前超声心动图。术中应用经食管超声心动图评价法乐氏四联症心内修复效果作了初步观察,提示法乐氏四联症心内修复术中应用经食管超声心动图有重要临床意义,重症法乐氏四联症心内修复术尤其需要,应用TEE评价清醒法乐氏四联症病人也是相当安全可行的。

This study was undertaken to assesss the abilities to evaluate Tetralogy of Fallot (TOF) by single planar transesophageal two—dimensinal echocardiography with Doppler color flow imaging (TEE) in the 28 patients (19 awake, 9 operating) with the range of age 12 to 40 years, lower—most weighing 36 kg. The results showed that the main pulmonary artery, bifurcation, distal right pulmonary artery, proximal left pulmonary arrery and atrial septal structure were optimally visualized by TEE, comparable to transthoracic echocardiography(TTE), but right ventricular outflow tract was not delineated in detail by TEE. The initial use of intraoperative TEE demonstrated that TEE can provide useful information to surgeons at the time of the completely repair for TOF, especially for severe TOF.
