摘　　要：分析１２３例继发孔型房间隔缺损（ＡＳＤ）病人的外科修补术资料，以探讨ＡＳＤ的形态学特征与经导管关闭的可行性。结果发现ＡＳＤ的病理解剖变异很大，分为七种类型：中央型６５．０％，下腔型１２．２％，部分筛孔型７．３％，完全筛孔型５．７％，上腔型４．１％，巨大型ＡＳＤ４．１％及后位型１．６％。缺损的平均长径为２６．５±８．７ｍｍ，短径为１５．５±６．１ｍｍ。解剖类型与缺损内径（长径≤２５ｍｍ）均适合经导管关闭者只有６２例（５０．４％），余约半数病例仍需外科治疗。To assess the morphology of ostium secundum atrial septal defect (ASD) and determine in what proportion transcatheter closure of ASD might be feasible,the intraoperative discription of 123 consecutive patients (44 males and 79 females,age median 161,range 3-42 years) operated on for repair of ASD were reviewed.The great variations in the anatomy of ASD in our patients were found:central type ASD accounts for 650%;inferior form 122%;partially fenstrated form 73%;completely fenstrated form 57%;superior form 41%;subtotal absence of atrial septum 41% and posterior form 16%.The mean major diameter of ASD by operative measurement was 265±87 mm,minor diameter 155±61 mm.Based on anatomical forms and dimensions of defect,it was postulated that only 504% of patients with ASD may be suitable for transcatheter closure,about half patients should be treated by surgery.The reason to be unsuitable for transcatheter closure was discussed.
