Abstract

To examine placental vascularization using three-dimensional power Doppler (3DPD) ultrasonography in pregnancies complicated by intrauterine growth restriction (IUGR). The present prospective study was conducted at the University of Szeged (Szeged, Hungary) from February 2012 to March 2013. Women with a singleton pregnancy who attended the maternity outpatient ward in the second or third trimester were enrolled consecutively. Women were divided into two groups: those with a normal pregnancy and those with a pregnancy complicated by IUGR. Three 3DPD indices-vascularization index (VI), flow index (FI), and vascularization flow index (VFI)-were assessed. A total of 223 women were enrolled: 171 were in the control group and 52 in the IUGR group. Median VI was 3.7% (interquartile range [IQR] 3.2%-4.2%) in the IUGR group and 10.1% (IQR 8.6%-10.9%) in the control group (P=0.001). Median FI was 40.0 (IQR 39.7-42.5) in the IUGR group and 45.1 (IQR 44.1-53.1) in the control group (P=0.012). Median VFI was 2.2 (IQR 2.1-2.4) in the IUGR group and 4.8 (IQR 4.4-5.3) in the control group (P<0.001). Placental vascularization was reduced in pregnancies complicated by IUGR.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
