摘要目的 总结早期治疗婴幼儿完全性房室间隔缺损的临床经验.方法 2007年1月至2012年4月收治完全性房室间隔缺损患儿61例,男32例,女29例,年龄2～36个月,中位数9.5个月,体重4.5～15 kg,平均(8.7±2.8)kg.60例接受了修补手术,改良单片法37例,双片法23例.另有1例患儿为双心室不对称型,行肺动脉环缩术.结果 改良单片法和双片法体外循环时间分别为(105±35)min和(135±41 )min,主动脉阻断时间分别为(82±23) min和(94±31) min.围手术期死亡5例,室间隔残余分流6例,Ⅲ度房室传导阻滞4例.随访43例,无远期死亡,房室瓣反流中度以下.结论 婴幼儿完全性房室间隔缺损患儿应尽早手术干预,改良单片法和双片法均可取得满意术后效果,前者可明显缩短手术时间.

abstractsObjective To summarize our experience on surgical correction of complete atrioventricular septal defect (AVSD) in infants.Methods From January 2007 to April 2012,61 infants who underwent surgical correction for AVSD were enrolled in this study.Their age ranged from 3 to 36 months old (median age,9.2 months old).Their body weight ranged from 4.5 to 15 kg (mean weight,8.7±2.8 kg).Among these 61 patients,37 underwent a modified single-patch technique for closure of the AVSD,23 underwent double patch repair,and the other one patient underwent pulmonary artery banding surgery for the unbalanced AVSD.Results Cardiopulmonary bypass duration in modified single-patch operation and double patch operation was 105±35 min and 135±41 min,respectively.The time of aorta blocking in modified single-patch operation and double patch operation was 82 ±23 min and 94±31 min,respectively.Five patients were dead in the perioperative period.Six patients had residual AVSD,and 4 patients had complete atrioventricular block.Forty three patients were followed up.Mild to moderate mitral valve regurgitation was observed in these patients.Conclusions Early corrective surgery for the infants with AVSD can get satisfactory results.The modified single-patch technique shortens operating time compared with double patch repair.
