【摘要】：目的评价婴幼儿在经胸超声心动图(TTE)引导下仅经静脉途径行动脉导管未闭(PDA)介入封堵术的效果,探讨TTE在婴幼儿PDA介入封堵术中的应用价值。方法回顾性研究6岁以下行PDA介入封堵术的患儿110例,根据不同的介入封堵方法分为常规组(按传统方法建立股动静脉双通道)和实验组(仅建立静脉通道)。两组相比较,评价实验组手术效果。结果两组技术成功率100%,常规组和实验组即刻、术后10min残余分流率分别为4%vs 8.3%、2%vs 3.3%,术后1d、1个月、3个月未见残余分流发生;TTE测量的PDA直径分别为(10.3±2.7)mm(4~16mm)vs(9.8±2.4)mm(4~16mm),封堵器大小为(12.0±3.0)mm(8~18mm)vs(12.3±3.0)mm(8~18mm);两组相比无统计学差异(P0.05)。常规组PDA造影测值为4~16mm,平均(11.1±2.9)mm,与该组TTE测值相比,无统计学差异(P0.05)。实验组手术时间、X线曝光时间明显小于常规组,有显著统计学差异(P0.001)。结论 TTE引导下仅经静脉途径行PDA介入封堵术可行安全简便,在婴幼儿经皮行PDA介入封堵术中具有重要价值。
[Abstract]:Objective to evaluate the effect of transcatheter closure of patent ductus arteriosus (PDA) under the guidance of transthoracic echocardiography (TTE) in infants, and to explore the value of TTE in the transcatheter closure of PDA. Methods 110 cases of children under 6 years old who underwent PDA interventional closure were retrospectively studied. According to different interventional occlusion methods, 110 children were divided into two groups: routine group (establishing dual femoral arteriovenous channels according to traditional method) and experimental group (establishing venous channels only). Compared with the two groups, the effect of operation in the experimental group was evaluated. Results the technical success rate of the two groups was 100%. The residual shunt rate of 10min was 10.3 卤2.7)mm(4~16mm)vs(9.8 卤2.4 卤4.16 mm and the size of occluder was 12.0 卤3.0)mm(8~18mm)vs(12.3 卤3.0 卤3.18 mm, respectively. There was no significant difference between the two groups in the diameter of 10min at 1 day, 1 month, and 3 months after operation (P < 0.05), and there was no significant difference between the two groups (P > 0.05), and the diameter of residual shunt was 10.3 卤2.4 卤2.4 卤4.16 mm and the size of occluder was 12.0 卤3.0mm 卤3.0mm respectively, and there was no significant difference between the two groups (P < 0.05). The average value of PDA in the routine group was 4.16 mm (11.1 卤2.9 mm). There was no significant difference between the conventional group and the TTE group (P 0.05). The time of X ray exposure in the experimental group was significantly lower than that in the routine group (P 0.001). Conclusion the transcatheter closure of PDA under TTE guidance is safe and convenient, and it is of great value in the percutaneous transcatheter closure of PDA in infants.
