产前超声诊断胎儿肢体-体壁综合征的价值

摘要

Objective To explore the value of prenatal ultrasound in early diagnosis of fetuses with limb body wall complex (LBWC).Methods A retrospective study was performed in 6 cases with LBWC, including ultrasound images and follow-up results.The ultrasonic features of LBWC were analyzed.Results 4 of these (4/6,66.7%) fetuses were diagnosed at 11~14 weeks of gestation.2 fetuses were diagnosed at 20 and 24 weeks.All the cases showed abdominal wall defect, spinal abnormality and umbilical cord abnormality.There were 5 cases of idiopathic scoliosis, and 1 case of twist into a corner.4 cases had too short umbilical cord, 1 had no umbilical cord, 1 displayed unsatisfactory.3 cases were shown limb abnormalities.3 cases associated with a single umbilical artery.2 cases presented with NT thickening.Conclusion Prenatal ultrasonography, especially 11~14 week ultrasonography can diagnose LBWC, so as to provide evidence for early clinical intervention.%目的 探讨产前超声特别是中孕早期超声诊断胎儿肢体-体壁综合征的价值.方法 回顾性分析产前超声诊断的6例胎儿肢体-体壁综合征的超声表现及随访结果,分析其声像图特点.结果 6例诊断的肢体-体壁综合征的胎儿4例于11~14周诊断,占66.7%,2例分别于20周及24周系统超声检查时发现.均有较大的腹壁缺损、脊柱及脐带异常.其中5例脊柱侧凸畸形,1例脊柱呈扭曲状, 1例脐带显示不满意,1例无脐带,4例脐带较短而细,3例合并肢体异常,3例伴有单脐动脉,2例NT增厚(分别为0.4cm;0.6cm).结论 产前超声特别是中孕早期超声是诊断胎儿肢体-体壁综合征最有价值的检查方法,对早期临床处理有重要意义.
