【摘要】 目的 应用Amplatzer封堵器治疗继发孔型房间隔缺损（ASD）并评价其疗效。方法 9例患者,男3例,女6例,年龄8～52（33.0±5.2）岁,体重22 kg以上。经临床、心电图、x线胸片和经超声心动图（TEE）检查诊断继发孔型ASD,导管法测定肺动脉收缩压24～46（24.4±5.5）mmHg（1mmHg=0.133 kPa）,经心内球囊测定法测定ASD直径11～30（23.3±6.2）mm。手术在X线透视和TEE监视下进行。用10F、11F或12F导管装载Amplatzer封堵器经皮穿刺插入封堵治疗ASD。术后24h、1、3、6个月行胸壁超声心动图和X线胸片评价效果。结果 手术全部获得成功,8例术后即时做TEE检查示ASD立即关闭,次日病人即能下床活动。1例有残余微量分流,1个月后仍然存在,6个月时分流消失。1例在术中发生脑栓塞,经及时用尿激酶溶栓治疗痊愈。结论 Amplatzer封堵器治疗继发孔型ASD是一种有效的非手术治疗方法,具有安全、操作简便、成功率高的特点。更多还原

【Abstract】 Objective Our purpose was to report Initial clinical application experience and assess the immediate and short-term effect of transcatheter closure secundum atrial septal defects (ASD) using Amplatzer atrial septal ocluder.Methods Procedures were perfomed under fluoroscopy and transesophageal echocardiography monitoring. Nine patients (3 male, 6 female) underwent attempted transcatheter closure of a ASD using the Amplatzer atrial septal ocluder device with 10F, 11F or 12F long sheath at a mediant age of 33.0±5.2 years (range 8 to 52 years) and weighed 22 kg or more. Other congenital cardiac anomanies which require surgery were excluded. The mediant diameter of ASD at its narrowest segement were mensureted with the balloon catheters was 23.3±6.2 mm (ranger 11 to 30 mm). Systolic pressures of pulmonary arteries were 24.4±5.5 mm Hg (24-46 mm Hg) with catheterization mensuration. After the procedure, TEE were perfomed immediately to find whether there any residual shunt retained. Follow-up evaluation was color flow mapping at 24 h, 1, 3 and 6-months after closure. Results Nine patients had successful device placement. Transesophageal echocardiography showed that 8 patients had complete immediate closure and one had a small residual shunt after the operation, and could get up in the next day. The complication of cerebral throumbus embolism occurred in one woman patient during the procedure. She accepted immediately thrombolysis therapy with urokinase and recovered after several days. Conclusion Transcatheter closure of secondum ASD using Amplatzer atrial septal occluder device is an effctive nonsurgical therapy method. The operation has specialities of simple, safe with a high succes rate of placement and a fine occlusion effect. Further clinical trias are underway.更多还原
