摘要
目的探讨房间隔膨胀瘤（ASA）在颈动脉正常脑卒中患者中的临床意义。方法选择有脑中风病史颈动脉正常的ASA病例36例作为A组，性别年龄相匹配的非脑中风病例68例作为B组，应用经胸超声心动图（TTE）获取心尖四腔心和大血管短轴切面，观察ASA最大膨出深度、膨出方向，随正常呼吸，循环周期膨胀瘤的运动，ASA瘤壁厚度，是否存在血栓，以及有无其他心脏异常。结果按ASA的膨出方向和运动情况分型，两组病例均以IB型居多，两组病例的各类型间差异无统计学意义；A组的瘤体深度及瘤壁厚度均较B组明显增加；A组ASA合并PFO的比例（10／36）高于B组（8／68）。结论ASA在颈动脉正常脑卒中患者的发病中扮演着重要的角色，超声心动图可以对ASA的特征作出准确的诊断，为临床提供更为有价值的信息。
Objective To investigate the clinical significance of atrial septal aneurysm （ASA） in patients with stroke and normal carotid arteries. Methods 36 patients with stroke and normal carotid arteries were included in the study （ group A）. These patients were compared with 68 age- and sex-matched patients without cerebral ischemic events who underwent echocardiography examination during the same period of time. The following parameters of the ASA were measured： maximal excursion or protrusion beyond the plane of the atrial septum, direction of protrusion, thickness of the wall, presence of theombi attaching to the wall and other structural abnormalities associated with ASA. Results No difference was found in direction of protrusion and incidence of oscillations between the two groups, the extent of bulging and thickness of wall in group A were greater than those in group B, more PFO were observed in group A. Conclusion Greater maximal excursion and thicker aneurysm wall of ASA is associated with a higher risk of cerebral isehemic event. Eehocardiography is a reliable means to detect ASA and its complications.
