摘　　要：目的:探讨西藏高原地区藏族老年性房间隔瘤(ASA)的超声表现。方法:回顾性分析西藏高原地区超声诊断ASA 20例,总结其超声声像图特点。结果:ASA全部发生在卵圆窝处,瘤样回声膨向右心房侧9例,占45%;膨向左心房侧10例,占50%,1例随心动周期左右摆动,占5%,分属Olivares-Reyes A分型标准的Ⅰ型、Ⅱ型和Ⅴ型。Ⅰ型瘤体突出平均高度为(1.33±0.40)cm,基底直径(2.1±0.4)cm;Ⅱ型瘤体突出平均高度为(0.85±0.22)cm,基底直径(1.5±0.3)cm。结论:西藏高原地区老年性ASA多发生在卵圆窝处,超声检查可作为ASA首选检查方法。AIM： To investigate the value of echocardiography in the diagnosis of senile atrial septal aneurysm （ASA） in Tibetan patients on the Tibet Plateau. METHODS： Ultrasonographic results of senile ASA in Tibetan patients were retrospectively studied and ultrasonographic characteristics were summarized. RESULTS： ASA were found to be located at fossa ovalis in all 20 cases. By Olivares- Reyes A standard （Type I with aneurysm projecting into the right atrium, type II aneurysm projecting into the left atrium and type V aneurysm swinging with the cardiac cycle）, nine cases （45%） were type I, 10 cases （50%） were type II and one case （5%） was type V. The average height and base diameter of type l and type II ASA were, respectively, （1.33±0.40） cm and （2.1±0.4） cm, and （0.85±0. 22） cm and （ 1.5±0. 3 ） cm. CONCLUSION ： Senile ASA in Tibetan patients on the Tibet Plateau is most often located at the position of the fossa ovalis. Ultrasonography is the first-choice examination for diagnosis of senile ASA.
