Summary
Pregnancy-induced hypertension (PIH) affects 3.2-4% of pregnancies globally. Placental examination reveals non-specific findings, but vascular changes correlate with Doppler sonography results.
Area of Science:
- Obstetrics and Gynecology
- Pathology
- Perinatology
Context:
- Pregnancy-induced hypertension (PIH) is a common complication, affecting 3.2-4% of pregnancies worldwide.
- PIH poses risks to both mother and child, necessitating thorough placental examination.
- Pathological-anatomical examination of the placenta is crucial in all PIH cases.
Purpose:
- To review pathomorphological findings in the placenta associated with pregnancy-induced hypertension.
- To assess the diagnostic value and correlation of placental findings with disease severity.
- To highlight specific placental pathologies and their relationship with Doppler sonography.
Summary:
- Pathomorphological findings in the feto-maternal border zone include defective extravillous cytotrophoblast invasion, arterio-/arteriolopathy, and fibrinoid necrosis.
- Disorders in the fetal placenta involve infarctions, obliterative angiopathy, fibrosis, and syncytial knots.
- While many placental findings lack specificity, vascular changes in the placental bed and villi correlate strongly with Doppler sonography.
- There is a general lack of correlation between the severity of PIH and overall placental morphology.
Impact:
- Understanding placental pathology in PIH can aid in risk assessment and patient management.
- Correlation of placental vascular findings with Doppler sonography may improve diagnostic accuracy.
- This review emphasizes the importance of placental examination in understanding PIH pathophysiology.
