摘要
目的 :分析永存动脉干 ( PTA)结构、血流动力学特征 ,并探讨切面的选择。方法 :应用彩色多普勒超声仪检测11例疑诊为 PTA患者的二维超声心动图 ( 2 DE)和彩色多普勒血流图 ( CDFI)。所有患者均使用剑突下、胸骨旁和胸骨上窝多部位和多切面检查心内结构。结果 :10例确诊为 PTA,1例诊断为肺动脉闭锁 ,心血管造影证实 11例均为 PTA。PTA 型 2例 , 型 1例 , 型 4例 , 型 4例。PTA起源左右心室之间 5例 ;主要起源于右心室 6例 ,骑跨率≥ 60 %。PTA双叶和四叶各 1例 ,三叶 9例。结论 :2 DE和 CDFI可用于识别 PTA病理解剖结构 ,血流动力学特征 ,且诊断符合率高 ( 91% )
AIM: To analyze structure of persistent truncus arteriosus(PTA), hemodynamics, and explore selection of view. MOTHODS: Color Doppler ultrasound system were used to detect two dimensional echocardiography (2DE) and color Doppler flow imaging (CDFI) of 11 patients suspected with PTA. All cases underwent assessment of the intracardic structures by subcastal, parasternal and suprasternal views. RESULTS: Among the 11 cases of PTA, 1 case of pulmonary artersia was diagnosed by 2DE and CDFI. 11 case of PTA was performed with angiocardiography. 10 cases were classified by 2DE and CDFI, which were 2 cases of type 1, 1 type II, 4 type III, and 3 type Ⅳ. 2DE and CDFI showed the truncus arteriosus originated from both ventricles equally in 5 cases and predominanly from the right ventricle in 6 cases with overriding rate ≥60%.The number of the truncal cusps included 1 case of bicuspid, 1 case of quadricuspid and 9 cases of tricuspid. CONCLUSION: 2DE and CDFI should be used to identify pathologic anatomy of abnormal structure of PTA and hemodynamics features. The diagnosis rate is high (91%).
