Specialized Care for Healthier Pregnancies and Births

Maternal Fetal Medicine physicians specialize in the diagnosis and treatment of women with
complications of pregnancy, preexisting medical conditions that may be impacted by pregnancy
and medical conditions that impact the pregnancy itself. Maternal Fetal Medicine specialists
collaborate with obstetricians in providing consultations, co-management or direct care for
patients with complications both before (pre-conceptional counseling) and during pregnancy.

Driscoll Health System Maternal Fetal Medicine was founded in 2008. Since then, we have
grown to include five maternal-fetal medicine specialists, supported by pediatric cardiology,
genetics, perinatal sonographers and nurses, and a clinical care coordinator, now providing care at seven locations. Our mission is to provide state-of-the-art maternal care, fetal diagnosis and treatment for the women of South Texas.

Maternal Fetal Medicine specialists are doctors who are specially trained to care for women with high-risk pregnancies. Mothers with diseases such as hypertension or diabetes, babies with possible genetic conditions or mothers expecting multiple babies can all benefit from the care of a Maternal Fetal Medicine specialist. These doctors receive two to three years of additional training that focuses on high-risk pregnancies, ultrasound techniques and fetal anomalies.  

Most women seek consultation from or care by a Maternal Fetal Medicine specialist because they are "at risk" and considering becoming pregnant or because they are pregnant and "high-risk," "complicated" or otherwise worried about their pregnancy. 

Patients undergoing diagnostic or therapeutic procedures during pregnancy, such as:  

  • Comprehensive ultrasound  
  • Chorionic villus sampling  
  • Genetic amniocentesis, fetal surgery or treatment  


Women with medical or surgical disorders, such as:  

  • Heart disease  
  • High blood pressure  
  • Preeclampsia (toxemia)  
  • Diabetes or other endocrine disorders  
  • Kidney or gastrointestinal disease  
  • Infectious diseases  


Healthy women whose pregnancy is at markedly increased risk for adverse outcome, such as:  

  • Abnormal AFP (alpha fetoprotein) blood test  
  • Twins, triplets or more  
  • Recurrent pre-term labor and delivery
  • Premature rupture of membranes 
  • Recurrent pregnancy loss
  • Suspected fetal growth restriction
