The application of prenatal ultrasound in pregnancy with several kinds of pathogen infection / 中华医学超声杂志（电子版）

ABSTRACT

Objective To investigate the fetal ultrasonographic features in pregnancies with Toxoplasma (TOX), rubella virus (RV), cytomegalovirus (CMV) and herpes simplex virus (HSV) infection. Methods From January 2011 to March 2013, prenatal ultrasound examination was performed in 545 fetuses with mothers of speciifc positive IgM of TOX, RV, CMV and HSV, detected by enzyme-linked immune sorbent assay (ELISA) in Nanjing Medical University Affiliated Suzhou Hospital. Ultrasonographic features were summarized and pregnancy outcome was followed up in fetuses with abnormal ifndings. Results Among the 545 fetuses, 56 cases with abnormal sonographic ifndings:6 cases with central nervous systerm abnormalities (2 intracranial calcifications, 4 hydrocephaly);9 cases with digestive system abnormalities (1 intrahepatic calcifications, 8 echogenic bowel);2 cases with heart abnormalities (1 interventricular septal defect, 1 right heart enlargement);17 cases with abnormal amniotic fluid volume (16 polyhydramnios, 1 oligohydramnios);3 cases with placental abnormality (1 thick placenta, 2 placenta abnormal calciifcation);13 cases with urinary systerm abmormality appearing as renal sinus separation;and 6 cases with other systerm abnormalities (1 neck lymphatic hygroma, 1 single umbilical artery, 1 sacrococygeal teratoma and 3 intrauterine growth restriction);2 cases of complicated abnormalities. Conclusions Prenatal ultrasonography is signiifcant in detecting serious fetal malformations, such as hydrocephaly, heart abnormalities and characteristic ultrasound features such as intracranial calciifcations, echogenic bowel, placenta abnormal calciifcation complicated with TOX, RV, CMV and HSV infection, providing valuable information for further clinical treatment, such as induced labour.
