二维超声心动图“骑跨征”图像特征及规律性研究

A study on imaging character and regularity of the “Straddle Sign” of two-dimensional echocardiography

目的:探讨二维超声心动图(2DE)“骑跨征”图像特征及规律性。方法:对2673例2DE“骑跨征”图像特征及规律性进行研究。2159例有心血管造影对照,2569例经手术证实。结果:2DE“骑跨征”与五种先心病共存,病例由多到少依次为法乐四联症、右室双出口、永存动脉干、室间隔缺损合并肺动脉高压和Taussig-Bing综合征。2662例为主动脉“骑跨征”,11例为肺动脉“骑跨征”。结论:①2DE“骑跨征”分为主动脉“骑跨征”和肺动脉“骑跨征”。②2DE“骑跨征”与五种先心病共存,前四种为主动脉“骑跨征”,后一种为肺动脉“骑跨征”。③主动脉“骑跨征”在一定程度上可反映病情轻重,但不是反映病情轻重的唯一指标,肺动脉“骑跨征”与病情轻重无关。④主动脉窦瘤、马凡综合征和主动脉右窦破入右心室三种心脏病还可表现假性主动脉“骑跨征”。

Objective:Probe into the imaging character and regularity of the'Straddle Sign'of two-dimensional echocar-diography(2DE).Methods:2673patients with the'Straddle Sign'of 2DE were studied,among them2159cases were also examined by angiocardiography,and2569cases were proved by operations.Results:It showed that the'Straddle Sign'are seen in5kinds of congenital heart disease,including tetralogy of Fallot,double outlet right ventricle,ventricular septal defect with pulmonary hypertension,persistent truncus arteriosus and Taussig-Bing Syndrome .Among them2662cases were aortic'Straddle Sign'and11cases were pulmonary artery'Straddle Sign'.Conclusion:①'Straddle Sign'of 2DE included aortic'Straddle Sign'and pulmonary artery'Straddle Sign'.②'Straddle Sign'on2DE can be found in5kinds of congenital heart disease,the first4kinds were aortic'Straddle Sign'and last one was pulmonary artery'Straddle Sign'.③Aortic'Straddle Sign'can reflect the severity of the disease,but was not the only index,and pulmonary artery'Straddle Sign'has no relation with the severity of the disease.④In aortic sinus aneurysm,Marfan's Syndrome and rupture of aortic right sinus a-neurysm into the right ventricle show false aortic'Straddle Sign'.
