We agree with the comments of Dr. Abdin Elshikh on our article titled “Fetal Gestational Age Determination using Ultrasound Placental Thickness” which was published in the January–March 2020 issue of the Journal of Medical Ultrasound.
Besides thalassemia/hemoglobinopathy mentioned by Dr. Elshikh, other causes of small placenta (hypertensive disease of pregnancy, fetal growth restriction, trisomy 18, dygynic triploidy, intrauterine infection, variations in placenta morphology, etc.) or placentomegaly (maternal anemia, maternal diabetes mellitus, hydrops fetalis, umbilical vein obstruction, placental chorioangioma, placental mesenchymal dysplasia, etc.) could also affect placenta thickness measurements – constituting the limitations of the method. Some of these abnormalities were the part of our exclusion criteria. Unsurprisingly, even the well-established biometric parameters (biparietal diameter, head circumference, abdominal circumference, and femur length) have their limitations. It is noteworthy that thickened placenta is seen in only 0.6%–7.8% of obstetric sonography.
