摘要
目的探讨多层螺旋CT(MSCT)在诊断房间隔瘤(ASA)中的应用价值。资料与方法根据瘤体膨出超过房间隔平面≥15mm或瘤基底部宽度≥15mm诊断ASA,回顾性分析9例ASA患者的CT表现。结果 8例瘤体突向右心房;6例位于卵圆窝水平。9例患者瘤体平均膨出15mm、瘤基底部平均宽度21mm。3例并发卵圆孔未闭及左向右分流。9例患者瘤体凹面及左心房内均未见血栓形成。结论 MSCT能直观显示房间隔膨出的形态、部位、大小及运动方式,可作为诊断ASA的一种简便、可靠的方法。
Objective To evalute the diagnostic value of multi slice CT in atrial septum aneurysm（ASA）. Materials and Methods ASA was defined according to criteria：（1） The width of aneurysm in the interatrial septum≥ 15 mm or（2）protrusion beyond the plane of the IAS ≥15 mm. CT findings of 9 cases with ASA were analyzed retrospectively. Resu-lts CT revealed 8 cases ASA protruding into the right atrium and 6 cases located at the fossa ovalis. The average diameter of the base of ASA was 21 mm,protrusion beyond the IAS was 15 mm. Three cases was combined with patent foramen ovale and left-to-right shunting. There were no evidence of thrombus formation on the concave aspect of the aneurysm and left atrium in all 9 cases. Conclusion The configuration,position,size and moving mode of ASA could be showed by MSCT. MSCT was an effective method for diagnosing ASA.
