非缺损型房间隔潜在通道的观测及其意义

THE MEASUREMENT AND SIGNIFICANCE OF THE POTENTIAL PASSAGEWAY ON NON-DEFECTIVE INTERATRIAL SEPTUM

目的 :为非创伤性房间隔穿刺提供解剖学依据。方法 :观察 4 5例成人心脏标本房间隔卵圆窝缘上部下方潜在通道的形态 ,测量潜在通道在左、右心房面开口的宽度、高度和其弧形长度。结果 :非缺损型房间隔在卵圆窝处有 37.78%存在潜在通道 ;潜在通道在左房面开口的宽度、高度和其弧形长度分别平均为 9.83± 4 .2 6mm ,2 .87± 2 .0 2mm ,13.71± 6 .5 3mm ,在右心房面分别平均为 8.75± 4 .4 5mm ,2 .2 6± 1.6 7mm ,11.93± 6 .82mm。结论 :37.78%的国人在房间隔存在潜在性通道 ,为无创伤性房间隔穿刺提供了形态学依据。

Objective:To provide anatomical foundation for non-traumatic interatrial septum puncturing. Methods:The morphology of the potential passageway at foramen ovale on interatrial septum in 45 grown-up heart samples was observed and the width and height and the curve length of the potential passageway of left and right atrial surface were measured. Results: 37.78% of non-defective interatrial septa possess the potential passageway at foramen ovale. The width and height and curve length of orifice of the potential passageway are 9.83±4.26mm,2.87±2.02mm, and 13.71±6.53mm respectively on left atrial surface,and 8.75±4.45mm,2.26±1.67mm, and 11.93±6.82mm respectively on right atrial surface.Conclusion:The rate of potential passageway on interatrial septum in Chinese is 37.78%, which provides morphological foundation for non-traumatic interatrial septum puncturing.
