实时三维超声在诊断胎儿体表结构畸形中作用的初步研究

目的：探讨实时三维超声在诊断胎儿体表结构畸形中的临床应用价值.方法：对37例可疑有体表结构畸形的胎儿行二维和实时三维超声检查,并随访妊娠结局证实.结果：37例畸形中,21例孕14～24周有体表结构畸形的胎儿,产前二维、实时三维超声诊断符合率分别为85.7%、100%;16例孕25～42周有体表畸形的胎儿,产前二维、实时三维超声诊断符合率无明显差别,均为100%.结论：实时三维超声可直观显示胎儿的结构情况,可以较早诊断胎儿的体表结构畸形,准确性优于二维超声.

Preliminery evaluation of four-dimensional ultrasound in the diagnosis of surface deformity in fetus

Objective: To assess the value of four-dimensional ultrasound in the diagnosis of surface deformity in fetus.Methods: Thirty-seven fetus of surface deformity were examined with two-dimensional ultrasound and four-dimensional ultrasound,and were followed up till delivery.Results: The accuracy of four-dimensional ultrasound was 100%,while that of two-dimensional ultrasound was 85.7% between 14 to 24 weeks of gestation.Conclusion: Four-dimensional ultrasound can offer more plentiful diagnostic infor-mation than two-dimensional ultrasound,and can diagnose fetal malformation early.
