经胸彩色多普勒超声心动图在房间隔缺损介入治疗中的临床价值

摘要

目的探讨经胸彩色多普勒超声心动图在房间隔缺损（ASD）介入治疗中的临床价值。方法30例中央型ASD患者，使用TTE进行术前筛选，多个切面测量ASD的大小及周边情况，选择封堵器型号，术中监测介入治疗过程，并对封堵成功患者进行术后随访观察。结果30例患者中，29例封堵成功，成功率为96.67%，其中1例封堵器释放后，可见少许残余分流，术后3 d、1个月仍有少许残余分流，术后3个月分流消失，其余封堵器位置固定，无并发症发生；1例ASD患者因房缺缘较软，支持力度不够，封堵失败，行外科修补术。结论超声心动图作为一种安全、无创、简便的检测手段，在ASD介入治疗中具有重要的临床价值。%Objective To investigate the clinical value of of transthoracic echocardiography (TTE) in interventional therapy of atrial septal defect (ASD). Methods TTE was performed in 30 cases of central type ASD before operation, the size of ASD and the surrounding structures were detected on various planes for occluder type selection. TTE was also applied for intraoperative monitoring and postoperative follow-up. Results In 30 patients, the ASD was successfully occluded in 29 patients with the success rate of 96.67%. Little residual shunt was observed in 1 case after occluder release,the shunt was observed 3 d and 1 month after operation, and it disappeared 3 months later. The position the occluder was fixed in other cases with no complications. In 1 case, the edge of the ASD was too soft to support the occluder, surgical neoplasty was performed after failure of occlusion. Conclusion As a safe, non-invasive, and simple method, TTE has important clinical value in interventional therapy of ASD.
