Fetal Circulation

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Area of Science:

Obstetrics and Gynecology
Maternal-Fetal Medicine
Reproductive Health

Background:

Placenta accreta spectrum (PAS) encompasses conditions of abnormal placental implantation.
The incidence of PAS has risen significantly in recent decades.
PAS poses severe clinical complications, necessitating comprehensive understanding and management.

Purpose of the Study:

To review and synthesize current evidence-based data on Placenta Accreta Spectrum.
To explore prevalence, risk factors, pathogenesis, and clinical aspects of PAS.
To propose future research directions and a management workflow for PAS.

Main Methods:

Comprehensive literature review of evidence-based data on PAS.
Synthesis of information regarding prevalence, risk factors, pathogenesis, and clinical presentation.
Development of a visualized management workflow for PAS.

Main Results:

The review summarizes key findings on PAS prevalence, risk factors, and pathogenesis.
Clinical presentation, prenatal screening, and management strategies are detailed.
A novel three-step visualized workflow (predelivery, during delivery, postdelivery) for PAS management is presented.

Conclusions:

PAS is an increasingly prevalent and serious obstetric complication.
Effective management requires a thorough understanding of its multifaceted aspects.
The proposed visualized workflow offers a structured approach to PAS patient care.
