The book guides clinicians through the diagnosis and management of fetal growth restriction (FGR) by detailing diagnostic criteria, including ultrasound biometry and Doppler studies. It differentiates between early and late-onset FGR and discusses various etiologies. Management strategies focus on surveillance, timing of delivery, and optimizing fetal well-being through careful monitoring of growth, amniotic fluid volume, and umbilical artery Doppler. The text emphasizes individualized care plans to balance the risks of prematurity against the risks of continued intrauterine compromise.

The 9th edition presents key advancements in fetal therapy and surgery, reflecting the rapid progress in this specialized field. It covers indications, techniques, and outcomes for various interventions, including fetoscopic laser photocoagulation for twin-twin transfusion syndrome, open fetal surgery for myelomeningocele, and intrauterine transfusions for fetal anemia. The book discusses the evolving role of minimally invasive procedures and the importance of specialized centers for performing these complex interventions, aiming to improve perinatal morbidity and mortality.

The book addresses the challenges of managing multiple gestations by detailing the increased risks associated with these pregnancies, such as preterm birth, preeclampsia, and fetal growth restriction. It covers specialized prenatal care, including frequent monitoring, screening for complications like twin-twin transfusion syndrome, and appropriate timing of delivery. The text emphasizes the importance of early determination of chorionicity and amnionicity to guide management and highlights strategies to optimize outcomes for both mothers and fetuses in multifetal pregnancies.

The book's approach to maternal cardiac disease in pregnancy involves a comprehensive assessment of various cardiac conditions, their physiological impact during pregnancy, and risk stratification. It details management strategies, including medical therapy adjustments, close hemodynamic monitoring, and planning for labor and delivery. The text emphasizes a collaborative approach with cardiologists to optimize maternal and fetal outcomes, providing guidance on counseling patients about potential risks and ensuring appropriate care throughout gestation and the postpartum period.

The 9th edition discusses the significant impact of maternal obesity on pregnancy outcomes, detailing increased risks for both mother and fetus. For the mother, these include higher rates of gestational diabetes, preeclampsia, thromboembolism, and complications during labor and delivery. For the fetus, risks include macrosomia, congenital anomalies, and stillbirth. The book outlines strategies for preconception counseling, weight management, and specialized prenatal care to mitigate these risks and improve overall maternal and fetal health.

The book provides comprehensive information regarding postpartum hemorrhage (PPH) management, covering its definition, risk factors, and various etiologies (e.g., uterine atony, trauma, retained placental tissue, coagulopathy). It details a systematic approach to diagnosis and treatment, including uterotonic agents, uterine massage, surgical interventions, and massive transfusion protocols. Emphasis is placed on preparedness, rapid response, and multidisciplinary team involvement to effectively manage this leading cause of maternal morbidity and mortality.
