摘　　要：目的：探讨经胸和多平面经食管超声心动图检测成人动脉导管未闭的价值。材料和方法：动脉导管未闭31例,于封堵术前行常规经胸和多平面经食管超声心动图检查,观察降主动脉和肺动脉之间的异常通道和彩色多普勒分流血流束,测量动脉导管内径。在封堵术中用球囊导管探测动脉导管内径。将经胸和多平面经食管超声心动图与球囊导管的测值进行对照。结果：经胸和多平面经食管超声心动图的测值与球囊导管测值均呈高度正相关,分别为r=0．84 (P＜0．01)和r=0．93(P＜0．01)。多平面经食管超声心动图的测值更接近于球囊导管的测值,二维图像和彩色多普勒血流显像更为清晰。结论：对于经胸超声心动图显示受限的成人动脉导管未闭,多平面经食管超声心动图是较好的补充诊断方法,并可为封堵治疗提供更多的定量诊断信息。Purpose： The value of transthoracic echocardiography （TIE） and muhiplanar transesophageal echocardiography （MTEE） in aduh patent ductus arteriosus （PDA） was assessed in light of angiographic evidence. Materials and Methods： Thirty-one patients with PDA, aging 26.48 ± 10.87yr（ 16 - 62）, underwent TIE followed by MTEE before interventional closure therapy using balloon-catheter. The abnormal passage between descending aorta and pulmonary artery was showed as a color Doppler flow shunt. The PDA diameter measured by TIE and MTEE was compared respectively with that by angiography during closure therapy. Results： PDA diameter measured by balloon- catheter correlated well with that by TIE（ r = 0. 84, P 〈 0.01 ） and MTEE（ r = 0. 93, P 〈 0.01 ）. With two-dimensional mapping and color Doppler flow imaging, MTEE showed a clearer visualization of PDA than TIE. Conclusion： MTEE is a better complementary diagnosis for aduh PDA, providing more quantitative information for therapeutic purpose.
