Fetal Warfarin Syndrome: Causes, Signs, and Treatment
Fetal warfarin syndrome is a condition that occurs in babies exposed to the medication warfarin while in the womb. It can have a significant impact on the health and development of the baby, affecting various aspects of their well-being. The primary concern with fetal warfarin syndrome is the potential for certain abnormalities or impairments that can arise as a result of exposure to the medication during pregnancy.
What are the Symptoms of Fetal Warfarin Syndrome
Fetal warfarin syndrome can lead to a range of developmental issues and physical abnormalities in babies exposed to the medication in utero.
- Growth retardation
- Facial dysmorphism
- Central nervous system abnormalities
- Eye abnormalities
- Limb defects

Get Second OpinionCauses of Fetal Warfarin Syndrome
Fetal warfarin syndrome primarily occurs when pregnant women use the anticoagulant medication warfarin, leading to a range of developmental abnormalities in the fetus.
- Exposure to warfarin during pregnancy
- Interruption of blood flow to the developing fetus
- Impaired bone and cartilage development in the fetus
Types of Fetal Warfarin Syndrome
Fetal warfarin syndrome can manifest in various ways, affecting different parts of the baby's body as it develops during pregnancy.
- Central Nervous System Abnormalities: Characterized by brain malformations leading to neurological deficits in babies exposed to warfarin in utero.
- Limb Deformities: Involves malformations of the limbs, such as shortened or missing bones, joint contractures, and other musculoskeletal abnormalities.
- Cardiac Anomalies: Refers to structural defects in the heart, including septal defects, valve abnormalities, and other congenital heart malformations.
- Ocular Abnormalities: Manifests as eye defects like microphthalmia, cataracts, or other vision impairments in infants affected by fetal warfarin exposure.
- Growth Retardation: Involves intrauterine growth restriction leading to low birth weight and overall smaller size at birth due to warfarin exposure during pregnancy.
Risk Factors
Fetal warfarin syndrome is caused by exposure to the anticoagulant medication warfarin during pregnancy, with risk factors including the timing and duration of exposure, dosage, and individual susceptibility.
- Maternal use of warfarin during pregnancy
- High doses of warfarin exposure
- Prolonged warfarin exposure during pregnancy
- Use of warfarin in the first trimester
- Genetic factors that affect warfarin metabolism

Diagnosis of Fetal Warfarin Syndrome
Fetal warfarin syndrome is typically diagnosed through a combination of medical history, physical examination, and specific signs observed in the newborn.
- Ultrasound
- Fetal echocardiography
- Amniocentesis
- Maternal blood tests
- Genetic testing
Treatment for Fetal Warfarin Syndrome
Fetal warfarin syndrome is generally managed through careful monitoring and support to minimize potential complications.
- Multidisciplinary Care: Involves a team of healthcare providers including specialists in cardiology, neurology, and genetics to manage the diverse symptoms of fetal warfarin syndrome.
- Symptomatic Treatment: Addressing individual symptoms such as heart defects, developmental delays, or facial abnormalities to improve the quality of life for affected individuals.
- Early Intervention Services: Providing support and therapies to address developmental delays and disabilities in infants with fetal warfarin syndrome.
- Surgical Interventions: May be necessary for correcting physical abnormalities like heart defects or limb malformations associated with fetal warfarin syndrome.
- Genetic Counseling: Helps individuals and families understand the genetic implications of fetal warfarin syndrome, make informed decisions, and access appropriate support services.

What is fetal warfarin syndrome?
Fetal warfarin syndrome is a condition that occurs when a pregnant woman takes the medication warfarin, leading to birth defects in the developing fetus.
What are the common features of fetal warfarin syndrome?
Common features include nasal hypoplasia (underdeveloped nose), stippled epiphyses (abnormal bone development), and growth restriction in the fetus.
How is fetal warfarin syndrome diagnosed?
Diagnosis is typically based on the mother's history of warfarin use during pregnancy, along with physical examinations and imaging studies of the fetus.
Can fetal warfarin syndrome be prevented?
Fetal warfarin syndrome can be prevented by avoiding the use of warfarin during pregnancy and using alternative anticoagulant medications that are safer for the developing fetus.
What are the potential long-term effects of fetal warfarin syndrome?
Long-term effects may include developmental delays, cognitive impairments, and other complications that require ongoing medical monitoring and support.
