摘要
目的 探讨能辅助诊断I型永存左上腔静脉的简易超声指标。方法 对 16例I型永存左上腔静脉患者和 16名正常人及 13名无永存左上腔静脉的先心病患者 ,应用超声在剑下声窗测量右上腔静脉和下腔静脉内径并计算二者的比值。结果 下腔静脉内径在三组患者之间差异无显著性意义 ,而I型永存左上腔静脉患者的右上腔静脉内径和右上腔静脉内径与下腔静脉内径的比值较其他两组患者明显减小 (P <0 .0 0 1)。当这一比值≤ 0 .75时 ,辅助诊断I型永存左上腔静脉的敏感性为 87% ,特异性为 96 %。结论 测量右上腔静脉内径与下腔静脉内径的比值简单易行 ,为I型永存左上腔静脉的诊断提供了一个便捷的新参数。
Objective To find asimple parameter for auxiliary diagnosis of type I persistent left superior vena cava(PLSVC).Methods The diameters of right superior vena cava(RSVC) and inferior vena cava(RIVC) were measured at subcostal window and the ratio of RSVC/RIVC was calculated in the patients of 16 PLSVC, 16 normal and 13 congenital heart disease without PLSVC.Results There were no significant difference between the PLSVC group and other two control groups, but the RSVC and RSVC/RIVC in PLSVC group were significantly lower than those in other two control groups(P< 0.001 ). When the value of RSVC/RIVC was ≤ 0.75 , the sensitivity for auxiliary diagnosis of type I PLSVC was 87% , the specificity was 96% . Conclusion RSVC/RIVC is a simple and valuable parameter for auxiliary diagnosis of type I persistent left superior vena cava.
