摘　　要：目的探讨经胸超声心动图胸骨上窝切面在动脉导管未闭（PDA）分型诊断中的价值。方法经胸超声心动图分别采用胸骨旁大动脉短轴观与胸骨上窝主动脉长轴观扫查65例PDA患者，测量未闭导管的主动脉侧与肺动脉侧内径，进行分型诊断并与血管造影结果比较。结果胸骨旁切面、胸骨上窝切面及血管造影显示PDA主动脉侧内径分别为（8．31±2．76）mm、（10．87±3．26）mm及（11．15±3．29）mm，肺动脉侧内径分别为（5．69±2．82）mm、（5．75±2．63）mm及（6．09±2．78）mm。胸骨旁切面、胸骨上窝切面及血管造影检出漏斗型PDA分别为12例、19例和19例，胸骨上窝切面检出率高于胸骨旁切面（x2=5．14，P〈0．025）。结论经胸骨上窝切面探测PDA，对主动脉侧内径测值相对准确，有利于PDA的分型诊断。Objective To explore the value of transthoracic echocardiographic suprasternal view in the diagnosis of the subtype of the patent ductus arteriosus（PDA）. Methods Sixty-five cases with PDA were examined by transthoracic echocardiograpbic suprasternal view and parasternal great artery short axis view respectively before closure therapy. The diameters of both the aotic and pulmonary side were detected, and subtype diagnoses were made. The results were compared with those from digital subtraction angiography （DSA）. Results The demonstrated rates of PDA were 100% on the parasternal great artery short axis and suprasternal views. Of the 65 cases, 12 cases, 19 cases and 19 cases were the funnel type of PDA checked on the parasternal great artery short axis view, suprasternal view and DSA respectively. The demonstrated rate of the parasternal great artery short axis view was lower than that of the suprasternal view （x2 = 5.14, P 〈0. 025）. The diameter of the aotic side of PDA was （8.31 ± 2.76） mm, （10.87 ± 3.26） mm and （11.15 ± 3.29） mm and the diameter of the pulmonary side of PDA was （5.69 ± 2.82） mm, （5.75 ± 2.63）mm and （6.09 ± 2.78）mm respectively on the above two views and DSA. Conclusions The diameter of the aotic side of PDA can be accurately detected by using superasternal view, which would be helpful for the diagnosis of PDA subtype.
