Congenital Cystic Adenomatoid Malformation Volume Ratio in Prenatal Assessment of Prognosis of Fetal Pulmonary Sequestrations

摘要

cqvip:This study aimed to evaluate the prognosis of pulmonary sequestration (PS) by measuring congenital cystic adenomatoid malformation volume ratio (CVR) value in fetal congenital PS.The fetal CVR in 49 cases of fetal PS diagnosed by prenatal ultrasound in Xiangyang No.1 People's Hospital from March 2010 to June 2017 were measured,and the clinical outcomes were observed.According to the prenatal ultrasound CVR value,49 fetuses diagnosed with PS were divided into 2 groups:group 1 with CVR>1.26,and group 2 with CVR1.26)(2.04%,1/4刃 of induced abortion,and 2 cases (CVR >1.26)(4.08%,2/49) of stillbirths.In group 1 (w=24),21 cases were bom alive,and the incidence rate of newborn respiratory distress and fetal edema was 100%(21/21) and 79.17%(19/24) respectively.In group 2 (n=25),there were 3 cases (12%,3/25) of newborn respiratory distress,3 cases (12%,3/25) of fetal edema,and the rate of live birth was 100%.There were statistically significant differences between the two groups in the incidence of fetal edema,postpartum respiratory symptoms and survival rate.CVR was a risk factor for PS and was associated with fetal prognosis.CVR in the midtrimester of pregnancy is an effective index to evaluate the prognosis of fetal PS.CVR≥1.26 is associated with an increased risk of fetal edema,infant respiratory distress and intrauterine or postnatal death.
