摘　　要：目的研究胎儿肢体-体壁综合征(LBWC)的超声图像特征,探讨产前超声在妊娠早期胎儿LBWC诊断中的价值。方法回顾性分析2018年8月—2023年8月我院38例产前早期(11~13^(+6)周)诊断的胎儿LBWC的超声资料及随访结果,分析其超声特征,提出超声对此类疾病的诊断思路。结果38例胎儿LBWC,脊柱发育异常38例(100.00%),不同程度胸腹裂38例(100.00%),肢体发育异常13例(34.21%),颅脑畸形6例(15.79%),颈部透明层增厚12例(31.58%),脐带异常38例(100.00%),单脐动脉3例(7.89%),脐带囊肿1例(2.64%)。结论妊娠早期产前超声能尽早发现LBWC,早期诊断对临床干预和妊娠决策具有重要的临床意义。Objective To investigate the ultrasonographic features of fetal limb-body wall syndrome(LBWC)and explore the value of prenatal ultrasound in the diagnosis of fetal LBWC syndrome during early pregnancy.Methods The ultrasonographic data and follow-up results of 38 cases of fetal LBWC diagnosed by prenatal ultrasound during early pregnancy(11-13^(+6)wk)were retrospectively analyzed,and their ultrasonographic characteristics were analyzed.Results Among the 38 fetuses with limb wall abnormalities,there were spinal dysplasia(38/38,100.00%),varying degrees of thoracoschisis and gastroschisis(38/38,100.00%),limb dysplasia in 13 cases(13/38,34.21%),craniocerebral malformations in 5 cases Ultrasound diagnosis of fetal LBWC(6/38,15.79%),thickening of the transparent layer of the neck in 12 cases(12/38,31.58%),and umbilical cord abnormalities in 38 cases(38/38,100.00%),single umbilical artery in 3 cases(3/38,7.89%),cyst of umbilical cord in 1case(1/38,2.64%).Conclusion Prenatal ultrasound in early pregnancy can detect LBWC as early as possible,and correct prenatal evaluation provides important guidance value for pregnancy decision-making and early intervention.
