    摘 要:目的 依据经食管超声心动图(TEE)测量值选择Amplatzer封堵器研究房间隔缺损(ASD)介入治疗的可行性. 方法 全组74(男26，女48)例，年龄7～64(31.6±16.4)岁.按照选择封堵器的最终依据不同，分为球囊测量组:41例，术中用球囊充盈测量ASD伸展径，根据ASD伸展径选择封堵器;非球囊测量组:33例，术中TEE测量ASD大小直接选择封堵器. 结果 两组一般情况、超声心动图测量值和封堵器直径等均无显著性差异.球囊测量组手术时间(78.1±16.8)min和透视时间(15.4±6.1)min均明显长于非球囊测量组的(56.6±12.5)min和(10.1±4.3)min(P<0.01).两组技术成功率为100%，完全闭合率无显著性差异(P>0.05).球囊组食道超声所测房缺大小和球囊伸展径均与所用封堵器大小相关良好，其相关系数分别为0.962和0.973(P<0.01). 结论 直接依据TEE测量值选择Amplatzer封堵器对部分ASD介入治疗是安全可行的.对于房缺周缘较长、较硬者;及边缘为硬缘和极软缘组成，而剔除极软缘者，TEE可直接指导Amplatzer封堵器型号的选择.对于房缺缘较软者，应结合球囊测量房缺伸展径选择封堵器.

    Abstract:AIM To probe into the feasibility of transcatheter closure of atrial septal defect(ASD)with Amplazer septal occluder(ASO)device directly guided by transesophageal e-chocardiography(TEE)measured diameter.METHODS There were74patients.The mean age was(31.6±16.4)years(ranged from7to64years).The patients were divided into2groups(balloon group and non-balloon group)accord-ing to the guide used in ASO selection.There were41pa-tients whose ASDs were occluded with ASO selected based on balloon stretched diameter(BSD)in balloon group.There were33patients in non-balloon group.TEE measured diame-ters were used for selection of ASO size.RESULTS There was no significant difference between the two groups in age ......
