评价小儿继发孔型房间隔缺损 (ASD)应用国产的房间隔缺损封堵器介入关闭小儿继发性中央型ASD的临床疗效。应用深圳市先健科技生产的房间隔缺损封堵器关闭继发孔中央型ASD 12例 ,经胸心脏彩超及导管球囊测量均适合封堵闭。患者经临床、X线平片及经胸超声检查诊断为ASD。术前所有患儿胸骨左缘第 2～ 3肋间均可闻及II～III级收缩期喷射性杂音 ,经胸心脏超声显示房间隔缺损直径 7～ 3 2 (平均 15 2 )mm ,根据球囊最大伸展直径选择≥ 1～ 2mm型号的ASD封堵器 ,在X线透视及床边超声心动图监视下关闭ASD ,记录术中、术后各相关检查指标 ,术后 1d、1个月、3个月随访。结果表明国产房间隔缺损封堵器封堵小儿继发孔ASD是安全、有效的。
To evaluate the clinical efficacy of atrial septal defect occluder (ASD) in children with secondary secundum atrial septal defect (ASD) after interventional closure of pediatric secondary central ASD. Application Shenzhen first Jian technology production of atrial septal defect occluder closed secondary central venous ASD 12 cases, via the thoracic echocardiography and catheter balloon measurement are suitable for closure closure. Patients by clinical, X-ray and transthoracic ultrasound diagnosis of ASD. All the patients had stenosis Ⅱ ~ Ⅲ intercostal space at the left margin of the sternum before they were diagnosed. The transseptal echocardiography showed atrial septal defect diameter of 7 ~ 32 (average 15 2) mm, ASD occluder ≥ 1 ~ 2mm was selected as the maximal extension diameter of the balloon, and the ASD was closed under fluoroscopy and bedside echocardiography. The intraoperative and postoperative related indexes were recorded. The postoperative 1d, 1 month, 3 months follow-up. The results show that domestic atrial septal defect occluder blocking secondary ASD in children is safe and effective.
