Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Area of Science:

Obstetrics and Gynecology
Maternal-Fetal Medicine
Radiology

Background:

Placenta accreta spectrum disorder (PASD) is the recommended terminology for abnormally adherent placentas.
PASD involves abnormal placental implantation, with placenta accreta characterized by direct myometrial adherence of chorionic villi.
Accurate antenatal diagnosis is critical for reducing maternal and fetal morbidity and mortality.

Framework:

The International Federation of Obstetrics and Gynecology (FIGO) recommends PASD terminology.
The American College of Radiology Appropriateness Criteria provide evidence-based guidelines for imaging and treatment.
Methodologies like RAND/UCLA and GRADE are used to evaluate procedures.

Implementation:

Suspected PASD necessitates prompt radiologic and clinical data collection.
Transabdominal ultrasound with Doppler and transvaginal ultrasound are key diagnostic imaging procedures.
Expert opinion may supplement evidence when data is limited.

Implications:

Timely and accurate diagnosis facilitates appropriate delivery strategies at specialized centers.
Improved imaging protocols can enhance management of PASD.
Adherence to evidence-based guidelines ensures optimal patient care for PASD.
