O43.112
Circumvallate placenta, second trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Circumvallate placenta is a condition that affects the placental structure during pregnancy. Specifically, it occurs when the placental membranes fold back on themselves at the edges, creating a raised, rolled border. This condition is most often diagnosed in the second trimester and can be associated with various pregnancy outcomes. Recognizing and understanding this condition can help manage and monitor pregnancy more effectively.
Causes & Symptoms
Clinical Causes: The exact cause of circumvallate placenta remains unknown, but factors such as abnormal placental development and vascular issues may play a role. Previous pregnancy complications or uterine abnormalities might contribute to its development. Nutritional deficiencies or autoimmune conditions have also been suggested as potential contributing factors. Lifestyle factors like smoking or substance use may influence placental development, though evidence is limited.
Key Symptoms: Some women may not experience any symptoms. Vaginal bleeding during pregnancy, which can range from light spotting to heavier bleeding. Abdominal pain or cramping. Unusual uterine tenderness. Decreased fetal movement in some cases. In certain instances, no symptoms are evident, and the condition is only diagnosed through ultrasound.
Diagnostic & Treatment
Diagnosis Path: Circumvallate placenta is primarily diagnosed through prenatal ultrasound examinations. During ultrasound scans, the sonographer may observe a thickened placental edge folding back on itself, creating a distinctive appearance. Additional imaging, such as 3D ultrasound or MRI, might be used in complex cases. Regular monitoring of fetal growth and well-being is vital, especially if the condition is identified early in pregnancy.
Treatment Protocols: Management of circumvallate placenta involves close observation and routine prenatal care to monitor fetal health. Specific treatments may include:
