摘　　要：目的　探讨超声心动图在 Amplatzer封堵器治疗动脉导管未闭中的应用价值。方法　封堵术前超声心动图测量 PDA直径、内径、肺动脉内径、左房、左室大小及收缩功能等指标。术中全程指导监测封堵器位置是否正常 ,有无残余分流。术后 3个月复查封堵器有无移位或脱落。结果　超声监测 PDA共 15例 ,均为管型 ,PDA直径 5～ 12 mm,平均 7.0 mm,Vmax=4 .5 m / s,近主动脉弓降部造影 PDA最窄处直径 6～ 13mm,平均 6 .8mm ,二者无显著差异 (P>0 .0 5 ) ,术后 3个月 CDFI示 :大血管水平无残余分流 ,左室腔及左房、肺动脉平均内径均明显减小。结论　超声心动图检查对 PDA的大小判断 ,对封堵适应征及术中指导监测术后复检封堵器位置 ,血流动力学评价有非常重要的价值。Objective To probe the echocardiographic value in transcatheter closure of patent ductus arteriosus using Amplatzer occlusion device.Methods The size of PDA ,the diameters of pulmonary artery,left atrium and ventricle were measured and the cardiac functions were calculated before operation.The position of the occlusion device were observed and the residual shunts were monitored in operation.Whether the occlusion device moved or shed off after 3 month was examined.Results In 15 cases with ductal type,the mean diameter of PDA was 7.0 mm on ultrasound,descending aortographies showed the mean diameter of the narrowest was 6.8 mm,and compared with the two methods,there was no significant difference (P>0.05).Three months later,echocardiography showed that residual shunt has disappeared.and the diameters of left atrium,left ventricle and pulmonary artery were decreased.Conclusions Echocardiography plays an important role for selecting suitable patients before operation,judging the diameter of PDA,deciding device selection and evaluating the homodynamic changes.
