目的 观察胎儿动脉导管的形态变化及其与孕周增加的关系,探讨其形态变化的临床意义.方法 应用多普勒超声诊断仪157次扫描26～40周妊娠三血管切面动脉导管形态,记录直线型、轻度弯曲(C型弯曲<90°)、明显弯曲(C型弯曲>90°)或S型动脉导管例数及是否合并动脉导管瘤(DAA).结果 随孕周增加,直线型动脉导管逐渐减少,C/S型逐渐增加,轻度弯曲型所占比例最多(42%～55%).2例C/S型动脉导管合并DAA.1例C型动脉导管合并DAA同时合并卵圆孔狭窄并房间隔瘤形成.结论 随孕周增加,动脉导管形态逐渐弯曲或合并DAA,不应把动脉导管的形态变化诊断为异常.发现动脉导管形态变化或合并DAA应仔细观察是否合并心脏其他结构异常.
目的 觀察胎兒動脈導管的形態變化及其與孕週增加的關繫,探討其形態變化的臨床意義.方法 應用多普勒超聲診斷儀157次掃描26～40週妊娠三血管切麵動脈導管形態,記錄直線型、輕度彎麯(C型彎麯<90°)、明顯彎麯(C型彎麯>90°)或S型動脈導管例數及是否閤併動脈導管瘤(DAA).結果 隨孕週增加,直線型動脈導管逐漸減少,C/S型逐漸增加,輕度彎麯型所佔比例最多(42%～55%).2例C/S型動脈導管閤併DAA.1例C型動脈導管閤併DAA同時閤併卵圓孔狹窄併房間隔瘤形成.結論 隨孕週增加,動脈導管形態逐漸彎麯或閤併DAA,不應把動脈導管的形態變化診斷為異常.髮現動脈導管形態變化或閤併DAA應仔細觀察是否閤併心髒其他結構異常.

Objective To assesment the relationship between the curvature variation of ductus arteriosus and pregnancy proceeds through ultrasound examination in the three-vessel view of fetal ductus arteriosus.Methods 157 ultrasound screenings during 26～40 weeks were performed on the ductus arteriousus.The ductus arteriousus was graded as:straight,mildly curved(C-shaped bending <90°from a straight line) and markedly curved(C-shaped bending >90°or S-shaped kinking).Ductus arteriosus aneurysm(DAA) was diagnosed when there was a tortuous ductus arteriosus with a dilation that protruded leftward of the aortic arch.Results The curvature was gradually changed with the increase of gestational age.The straight ductus arteriosus steadily decreased,while the marked curvature increased.The proportion with mild curvature was mainly at all cases.There were 3 cases in which C-shaped or S-shaped ductus arteriosus with ductus arteriosus aneurysm were seen and one of them with foramen ovale closure.Conclusions The configuration of the ductus arteriosus is variable and trends to become more curved as pregnancy proceeds.Marked curvature or tortuosity of the ductus arteriosus should not be misinterpreted as a great vessel anomaly,if ducuts arteriosus is with aneurysm,echocardiography examination should be done in oder to find any abnormal heart structure.
