Placental position refers to the location of the placenta within the uterus, which can impact pregnancy outcomes and delivery methods. It is typically assessed through ultrasound and can be classified as anterior, posterior, fundal, lateral, or previa, each carrying different implications for maternal and fetal health.

Delivery methods

Ultrasound assessment is a non-invasive diagnostic tool that uses high-frequency sound waves to produce images of structures within the body, aiding in the evaluation and management of various medical conditions. It is widely used due to its safety, real-time imaging capabilities, and ability to assess soft tissues, organs, and blood flow without the use of ionizing radiation.

Ultrasound Assessment

An anterior placenta is when the placenta attaches to the front wall of the uterus, which can sometimes make it more challenging to feel fetal movements and may slightly alter the approach to certain prenatal procedures. While generally not a cause for concern, it is important for healthcare providers to monitor its position during pregnancy to ensure it does not interfere with delivery.

Anterior Placenta

A posterior placenta is one that attaches to the back wall of the uterus, which is considered a normal and common position during pregnancy. This positioning generally does not affect the course of pregnancy and delivery, but it can influence the perception of fetal movements, often felt later and less prominently than with an anterior placenta.

Posterior Placenta

A fundal placenta is located at the top of the uterus and is generally considered a normal and healthy position for the placenta during pregnancy. This positioning often indicates a lower risk of complications compared to placentas located near the cervix, such as placenta previa.

Fundal Placenta

A lateral placenta refers to the positioning of the placenta on either the left or right side of the uterus, which is generally considered a normal variation in placental placement. Its position is typically monitored through ultrasound to ensure it does not obstruct the cervix, which could complicate delivery if it leads to conditions like placenta previa.
