B超诊断胎儿颈部囊性淋巴管瘤22例分析

Prenatal Diagnosis of Fetal Nuchal Cystic Hygroma in 22 Cases

目的：探讨胎儿颈部囊性淋巴管瘤的早期诊断，原因分析及预后。方法：对２２例经Ｂ型超声检查发现的胎儿颈部囊性淋巴管瘤进行回顾性分析。结果：本病多在１５～１６周间经Ｂ超检查得到诊断。其中９例经产妇中，５例有不良妊娠史（死产、自然流产和畸形儿分娩史）。１０例胎儿染色体检查中有４例（４０％）出现异常。２２例中只有３例妊娠至足月分娩，其中２例新生儿存活，１例死亡。结论：本病是较常见的胎儿形态异常之一，大多预后不良。Ｂ超及染色体检查是本病的重要诊断方法。

Objective: To investigate the early diagnosis and prognosis of fetal nuchal cystic hygroma. Methods: 22 cases of fetal nuchal cystic hygroma diagnosed in uterus were analyzed retrospectively. Results: Most of the cases were diagnosed by B ultrasound between 15～26 gestational weeks. 55.9% of the multipara had abnormal pregnant history, and 40% (4/10) of fetuses with karyotype performed had chrosome abnormality. Except for fetal deaths and induced abortions, 3 cases had term deliveries: one neonatal death, one was born with hygroma of 5.9 cm×3.7 cm and transferred for surgery, and the other one with hygroma disappeared at the 37th week and baby was born at 40 week with normal appearance.Conclusions: This disease is one of common fetal morphological abnormalities. Few may recover spontaneously but most have poor outcomes.
