Dear Editor,
We agree with the comments of Dr. Abdin Elshikh on our article titled “Fetal Gestational Age Determination using Ultrasound Placental Thickness” which was published[1] in the January–March 2020 issue of the Journal of Medical Ultrasound.
Besides thalassemia/hemoglobinopathy mentioned by Dr. Elshikh, other causes of small placenta[2] (hypertensive disease of pregnancy, fetal growth restriction, trisomy 18, dygynic triploidy, intrauterine infection, variations in placenta morphology, etc.) or placentomegaly[3] (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.[4] It is noteworthy that thickened placenta is seen in only 0.6%–7.8% of obstetric sonography.[5]
