| 目的 探讨胎儿心脏内强回声灶(EIF)的临床意义。方法 用胎儿超声心动图检测正常孕妇的胎儿6694例,并与畸形胎儿或染色体异常胎儿EIF发生率进行比较,对胎儿EIF进行随访。结果 ①正常孕妇人群中胎儿EIF发生率为0.73%,与畸形胎儿或染色体异常胎儿EIF发生率1.61%,比较没有明显统计学意义(P＞0.05);②<35岁孕妇与≥35岁孕妇,其胎儿EIF发生率没有明显统计学差异(P＞0.05)。结论 对于发现单纯胎儿EIF而没有合并心内或其他畸形,EIF并没有太多的临床意义,仅能作为提示胎儿畸形或染色体异常的筛选线索。 |

| Objective To assess the clinical significance of small intracardiac echogenic foci in the fetuses. Methods Fetal echocardiographic examination was performed for echogenic intracardiac foci (EIF) in 6694 normal fetuses, whose incidence rate of EIF was compared with that of fetuses with malformation or chromosomal abnormality. All the fetuses were followed up. Results The incidence of EIF was 0.73% in the normal group, and 1.61% in the fetuses with malformation or chromosomal abnormality. But there was no significant difference between the two groups (P＞0.05). Similarly, the incidence of EIF in fetuses whose mothers were less than 35 years old was not significant different from that of fetuses whose mothers were more than or equal to 35 years old (P＞0.05). Conclusion It was not valuable that the EIF was emergedin the fetal heart without complicating any malformation. It only could be used as a screening clue for indicating fetal malformation or chromosomal abnormality. |
