摘　　要：目的分析胎儿先天性肺囊性腺瘤样畸形(CCAM)的产前超声特征。方法选择2014年1月至2019年8月本院收治的疑似存在胎儿CCAM的100例孕妇作为研究对象,均接受产前超声检查。以随访结果为金标准,对产前超声检查结果、超声特征进行分析,观察并发症发生情况和妊娠结局,比较胎儿患侧和健侧的超声肺脏回声强度值。结果CCAM的产前超声检出率为80.00%。80例CCAM中,Ⅰ型、Ⅱ型、Ⅲ型的检出率分别为60.00%、12.50%、27.50%;左侧、右侧、双侧病变分布比例分别为51.25%、37.50%、11.25%;肺动脉分支来源血供未探及比例更高,为67.50%;并发症以纵膈移位(77.50%)发生率最高,其次为羊水偏多(31.25%)、腹水(18.75%);活产率、引产率分别为56.25%、43.75%。产前超声检查的检出率与引产后或分娩后结果比较,差异无统计学意义(P>0.05)。CCAMⅠ型、Ⅱ型、Ⅲ型胎儿患侧肺脏回声强度值均高于健侧,差异具有统计学意义(P<0.05)。结论产前超声检查在胎儿CCAM中具有较高的诊断准确率,且肺脏回声强度值可为临床鉴别诊断病变类型提供参考,能明确病变范围和并发症发生情况,并对妊娠结局进行预测。Objective To analyze the prenatal ultrasonographic characteristics of congenital cystic adenomatoid malformation(CCAM)in fetuses.Methods A total of 100 pregnant women with suspected fetal CCAM admitted in our hospital from January 2014 to August 2019 were selected as the research objects,and all of them received prenatal ultrasound examination.Based on the follow-up results as the gold standard,the prenatal ultrasound examination results and ultrasonographic characteristics were analyzed,the incidence of complications and pregnancy outcome were observed,and the values of ultrasonic pulmonary echo intensity in the affected side and healthy side of fetuses were compared.Results The detection rate of CCAM was 80.00%by prenatal ultrosound.In 80 cases of CCAM,the detection rates of type Ⅰ,type Ⅱ and type Ⅲ were 60.00%,12.50% and 27.50% respectively;the distribution proportions of lesions on the left,right and bilateral sides were 51.25%,37.50% and 11.25% respectively;the proportion of undetected blood supply of pulmonary artery branches was higher,accounting for 67.50%;the highest incidence of complications was mediastinal displacement(77.50%),followed by excessive amniotic fluid(31.25%)and ascites(18.75%);the live birth rate and induced labor rate were 56.25% and 43.75%respectively.There was no significant difference between the detection rate of prenatal ultrasound and the results after induced labor or delivery(P>0.05).The value of pulmonary echo intensity of the affected side of CCAM type Ⅰ,Ⅱ and Ⅲ fetuses were higher than those of the healthy side,and the differences were statistically significant(P<0.05).Conclusion Prenatal ultrasound examination has a high diagnostic accuracy rate in CCAM of fetuses.The value of pulmonary echo intensity can provide reference for clinical differential diagnosis of lesion types,clarify the lesion range and complications,and predict the pregnancy outcome.
