目的利用X线与超声心动图相结合评价经导管置入国产封堵器治疗房间隔缺损(ASD)的疗效。方法38例ASD患者均在透视及经胸超声心动图(TTE)引导下置入封堵器。术前的X线、彩超资料作为术前组,术后6个月的X线、彩超资料作为术后组,术前组和术后组从心脏大血管各径线、血液分流、各房室内径、压力及肺血等方面进行对照分析,全面评价治疗效果。结果所有病例手术均获成功,技术成功率100%封堵。封堵术后X线检查示心脏表面积、肺动脉段基线(P1)、肺动脉主干横径(P2)、肺动脉段突出度(P3)、右下肺动脉宽径方面与术前比较差异有显著性意义(P<0.05),而心胸比率、右心房宽径(RAI)、右心房心高比率(Rah/Hh)、主动脉结宽径(A2)方面差异无显著性意义(P>0.05)。肺血均减少,透视下“肺门舞蹈”征消失。TTE检查无残余分流及再通,各房室内径缩小,压力降至正常。结论ASD介入封堵术是一种安全、有效的治疗方法。
Objective To evaluate the efficacy of transcatheter catheterization of atrial septal defect (ASD) combined with echocardiography. Methods Thirty-eight patients with ASD underwent transcranial echocardiography (TTE) guided by occluder. Preoperative X-ray, ultrasonography as a preoperative group, postoperative 6 months of X-ray, color Doppler ultrasound data as the postoperative group, preoperative group and postoperative group from the large blood vessels of the heart line, shunt, the atrioventricular Diameter, pressure and pulmonary blood and other aspects of control analysis, a comprehensive evaluation of the treatment effect. Results All cases were successful in operation, the technical success rate of 100% blocked. X-ray examination showed that the surface area of the heart, the baseline of the pulmonary artery (P1), the diameter of the main pulmonary artery (P2), the prominent pulmonary artery (P3) and the right lower pulmonary artery (P <0.05). There was no significant difference in cardiothoracic ratio, right atrium width (RAI), right atrium heart rate (Rah / Hh) and aortic node width (A2) Pulmonary blood are reduced, under fluoroscopy “Hindu dance ” sign disappeared. TTE no residual shunt and recanalization, the atrioventricular diameter narrowed, the pressure dropped to normal. Conclusion ASD interventional closure is a safe and effective treatment.
