| 目的 观察胎儿淋巴管畸形(LM)超声表现与妊娠结局的关联性。方法 回顾性纳入75胎经产前超声初次诊断的胎儿LM,按发生部位将其分为颈部组(n=55)与其他部位组(其他组,n=20);根据超声所见对胎儿LM进行分型,囊肿分隔数＞3个为Ⅰ型(n=34)、≤3个为Ⅱ型(n=31),以单纯性囊肿为Ⅲ型(n=7)、囊实混合性病变(n=3)为Ⅳ型LM。将终止妊娠或胎儿宫内死亡判定为妊娠结局不良,以继续妊娠且胎儿存活至分娩为妊娠结局良好。利用多因素logistic回归分析于胎儿LM产前超声表现中筛选妊娠结局的独立预测因素。结果 75胎中,45胎不良妊娠结局,包括颈部组43胎、其他组2胎。颈部组LM检出孕周早于其他组(P＜0.05)。颈部组40胎、非颈部组4胎合并其他异常,颈部组合并其他异常占比(72.73%,40/55)和不良妊娠结局占比(78.18%,43/55)均高于其他组[分别为20.00%(4/20)及10.00%(2/20),P均＜0.05]。LM检出孕周小、发生于颈部及合并其他异常均可用于独立预测妊娠结局不良(P均＜0.05)。结论 胎儿 LM发生于颈部、检出孕周小及合并其他异常提示妊娠结局不良可能性大。 |

| Objective To observe the correlations of ultrasonic findings of fetal lymphatic malformation (LM) and outcomes of pregnancy. Methods A total of 75 fetuses with LM initially detected by ultrasound were retrospectively collected and divided into cervical group (n=55) and other location group (n=20) based on the site of LM. Then fetal LM were classified into 4 types according to ultrasonic findings. Cysts with more than 3 septa were classified as typeⅠ (n=34), while those with less than or equal to 3 septa were identified as type Ⅱ (n=31), simple cyst lesions were regarded as type Ⅲ (n=7), and mixed cystic-solid lesion were classified as type Ⅳ LM (n=3). Poor pregnancy outcomes were defined as termination of pregnancy or intrauterine fetal death, while favorable pregnancy outcome was defined as continuation of pregnancy with fetal survival to delivery. Multivariable logistic regression analysis was used to screen independent predictors of pregnancy outcomes from prenatal ultrasound findings. Results Among 75 fetuses, poor pregnancy outcomes occurred in 45 ones, including 43 in cervical group and 2 in other location group. The gestational age at diagnosis of LM was earlier in cervical group than in other location group (P＜0.05). In cervical group, 40 fetuses were found with associated anomalies, while in other location group, 4 fetuses had associated anomalies. The proportion of associated anomalies in cervical group (72.73%[40/55]) and of poor pregnancy outcomes (78.18%[43/55]) were both higher than those in other location group (20.00%[4/20] and 10.00%[2/20], respectively, both P＜0.05). Earlier gestational age at diagnosis of LM, location in neck and presence of associated anomalies were all independent predictors of poor pregnancy outcomes of fetal LM (all P＜0.05). Conclusion Fetal LM located in neck, diagnosed at earlier gestational age and with associated anomalies indicated high probability of poor pregnancy outcomes. |
