High Risk Pregnancy Care:

High risk pregnancies are referred to our Perinatology centers. The physicians at Garden OB/GYN Perinatology have been providing care to pregnant women in New York since 2007. Our physicians are Obstetricians that have received additional training in the subspecialty of Maternal-Fetal Medicine.

What is a high risk pregnancy?

If a pregnancy is thought to have potential complications that could impact the health of the mother and/or her baby, the pregnancy may be considered a high-risk pregnancy. When a pregnancy is identified as high-risk, it is important that the mother visit a high-risk specialist, in addition to her regular obstetrician, to ensure the highest quality care, treatment and health outcome for her and her developing baby.

Risk Factors & Potential Complications For High-Risk Pregnancies Include:

  • Maternal Age: Mothers under the age of 17 or over the age of 35 may be at a higher risk of having pregnancy complications
  • Existing Health Conditions: If you have high blood pressure, diabetes, an autoimmune disease, STDs or HIV, a history of miscarriages, a family history of genetic disorders, or problems with your heart, kidney or lung, you may be at a higher risk of having a high-risk pregnancy
  • Medical Conditions During Pregnancy:
    • If you develop a condition called preeclampsia during your pregnancy, which is characterized by high-blood pressure, hand and feet swelling, and protein in your urine, your pregnancy may be considered high-risk. This is because, if left untreated, preeclampsia can lead to serious, and even fatal, pregnancy complications for the mother and/or baby.
    • If you also develop gestational diabetes during your pregnancy, you will likely be considered high-risk. However, proper treatment can help ensure a healthy pregnancy.
  • Complications During Pregnancy: If you experience premature labor, are carrying more than one baby during your pregnancy (such as twins or triplets, etc.), or if your pregnancy doctor discovers your placenta is covering your cervix, which is known as a condition called placenta previa, or if your doctor identifies fetal problems during your ultrasound, your pregnancy may be considered high-risk

Why Our Patients Choose Us For Their High Risk Pregnancy

Our Services

  • We provide co-managed (with obstetricians) prenatal care for patients with both low and high-risk pregnancies;
  • We provide consultation and recommendations for pregnant patients under the care of another health care provider;
  • We carry out detailed ultrasounds for pregnant women with or without a referral (please see the ultrasound section);
  • We provide genetic screening and prenatal diagnostic services;
  • We provide preconception counseling to women to assess overall health, pregnancy related risks and recommendations to optimize future pregnancy outcomes
Special Services:
  • Nuchal Translucency - We offer A nuchal scan is a sonographic prenatal screening scan (ultrasound) to help identify higher risks of Down syndrome in a fetus, particularly for older women who have higher risks of such pregnancies. High thickness measurements are also associated with congenital heart defect.[1] The scan is carried out at 11–13.6 weeks pregnancy and assesses the amount of fluid behind the neck of the fetus - also known as the nuchal fold or 'the nuchal translucency'. Fetuses at risk of Down tend to have a higher amount of fluid around the neck. The scan may also help confirm both the accuracy of the pregnancy dates and the fetal viability. Its high definition imaging may also detect other less common chromosomal abnormalities.
    All women, whatever their age, have a small risk of delivering a baby with a physical or Intellectual disability. The nuchal scan helps doctors and midwives to estimate the risk of the fetus having Down syndrome or other defects more accurately than by maternal age alone.
  • The Genetic Sonogram - We offer genetic sonograms for our high-risk patients, which has been shown in clinical studies to increase Down syndrome detection rates.
    The addition of genetic sonography can increase detection rates and maximize the accuracy of noninvasive testing for Down syndrome during the second trimester of pregnancy.
  • 3D / 4D Ultrasound - We offer ultrasounds, sometimes referred to as sonograms, which are medical tests that use high frequency sound waves to produce a picture of the organs in the body. In the case of pregnancy, ultrasounds are routinely prescribed to produce an image of the fetus. A 4D ultrasound uses a special sonogram machine and takes images from a few different angles, which reveal more detailed images of the fetus, such as facial features. It can also capture movements made by the baby during the procedure.

    3D Sonogram is a standard ultrasound, which only provides a two-dimensional image of the fetus. They are usually ordered in pregnancy for a variety of reasons, such as evaluating development of the baby, determining gestational age and identifying any abnormalities. Although the standard ultrasound produces a picture of the fetus, it may take a trained sonographer or a doctor to identify features and body parts. Keepsake photos are given to the patient, however they are often grainy.

    Occasionally, a two-dimensional ultrasound may indicate a problem and a more sophisticated 4D ultrasound is needed to confirm an abnormality. For many pregnant women, there is no medical need for a 4D ultrasound, however the mom-to-be wants to get a better look at her baby. Most centers that perform a 4D ultrasound, recommend the test is performed after twenty-five weeks gestation. The baby is usually big enough to see features clearly.
  • Fetal Heart Evaluation - We offer Fetal Heart Evaluations to help detect fetal heart abnormalities. Such abnormalities are rare and are only found in 0.4% to 1.1% of all live births. Early detection of heart issues, including detecting heart defects during pregnancy, before birth can help reduce infant mortality and other birth defects.

Our dedicated team of specialists work together closely with each other, our patients and other health care providers to ensure the highest level of care for pregnant women or women contemplating pregnancy.
