High Risk Clinic

Overview

Expecting twins, triplets or more is rare—only about three percent of pregnancies involve multiples. The High-Risk Multiples Clinic at The Ottawa Hospital’s General Campus is here to support you through this unique experience. Our goal is to provide clear, up-to-date information about your health and your babies’ health throughout your pregnancy and after delivery. 

The General Campus is the referral centre for tertiary-level perinatal care in Eastern Ontario and Western Quebec. This means we care for people with the most complex pregnancies and the smallest, most vulnerable newborns.  

We work closely with other hospitals in the Champlain region to ensure that patients receive the right level of care at the right location.  

For example, someone expecting twins who goes into labour before 32 weeks would be transferred to the General Campus, where our Level III Neonatal Intensive Care Unit (NICU) is located. 


Services

For multiple pregnancies, the team offers a full range of services. These include diagnosis and aneuploidy screening in the first trimester, genetic screening and diagnosis, detailed anatomy review, diagnosis and management of complex and specialized twin conditions and therapeutic twin procedures.

Other maternal fetal medicine services provided to our patients include:

  • Obstetrical Ultrasound.
  • 2D and 3D imaging services from first trimester to delivery.
  • Nuchal translucency screening (11 to 14 weeks).
  • Ultrasound guided amniocentesis (starting at 15 weeks).
  • Comprehensive fetal anatomic survey (at 18 to 22 weeks).
  • Fetal Neurosonography.
  • Diagnosis and surveillance of fetal anomalies and placental disorders.
  • Diagnosis of special twin conditions.
  • Assessment of fetal wellbeing from viability to term.
  • Genetic counseling (in conjunction with the Medical Genetics team at CHEO).
    • First and second trimester genetics screening.
    • Non-invasive prenatal testing and invasive fetal diagnosis (amniocentesis and CVS).
  • Antenatal consultation with the neonatology service.
  • Management of fetal Rh blood incompatibility.
  • Diagnosis of fetal anemia or thrombocytopenia (low platelets).
  • Invasive fetal diagnostic procedures.
  • Therapeutic procedures such as intrauterine blood sampling and fetal transfusions.
  • Prevention of preterm birth with risk assessment and cervical assessment by ultrasound.
  • Medical and surgical interventions (cervical cerclage) to reduce incidence of preterm birth.
  • Management of placental-mediated disorders (such as intrauterine growth restriction, hypertensive disorders of pregnancy and abnormal placentation such as placenta previa, and morbidly adherent placenta Accreta).
  • Management of complex maternal medical and surgical conditions in pregnancy and collaboration with other specialties to optimize outcomes for both mother and baby. 

Team

The Maternal Fetal Medicine team at the General Campus provides care through a multidisciplinary approach. This includes physicians, nurses and highly trained allied health professionals such as ultrasound sonographers, social workers, dietitians and perinatal mental health specialists.

Our partners

Care of a pregnant woman and her fetus involves specialists from a variety of allied health fields. Multidisciplinary rounds involving the Maternal Fetal Medicine team and allied specialties take place on a weekly basis to provide comprehensive and up-to-date care of our high-risk pregnancy patients. Here are some of these services: 

The Level III Neonatal Intensive Care Unit (NICU) is housed at the General Campus. Within the region of Eastern Ontario and Western Quebec, women at risk of preterm birth (twins and higher order multiples less than 32 weeks and singletons less than 30 weeks) are transferred to the General Campus for care. Premature twins born under 32 weeks gestation are admitted to the Level III NICU at the General Campus. Other premature newborns between 30 and 36 weeks may also be cared for in this unit or at the Level II NICU at the Civic Campus site.  

Babies with anatomic structural problems such as heart defects or other anomalies are born at the General Campus but will be transferred to the Children’s Hospital of Eastern Ontario (CHEO) for pediatric surgery. The Neonatology service provides antenatal counselling for mothers at risk of preterm delivery (such as twins or triplets) or other fetal problems that may require admission to the NICU.

Geneticists and genetic counsellors at CHEO play an important role in daily care of patients with high-risk pregnancies. They provided in depth counselling regarding risks of genetic diseases, the risks and benefits of non-invasive and invasive genetic screening and diagnosis, and up-to-date information on the availability of highly specialized prenatal testing for rare genetic disorders. 

Specialists in fetal diagnosis of congenital heart diseases work closely with us to provide prenatal diagnosis of fetal cardiac defects. Initial screening by fetal ultrasound takes place at both campuses of The Ottawa Hospital and detailed fetal heart examination with formal fetal echocardiography is done at both the General Campus and CHEO with the pediatric cardiologist in attendance. 

Pediatric radiologists at CHEO provide fetal MRI services for our patients for enhanced imaging of certain fetal anomalies, in particular, structural differences involving the fetal central nervous system. 

In conjunction with medical internists, the unit provides concurrent care of patients with medical problems of pregnancy such as hypertension, diabetes, thyroid disease and clotting disorders. 

Obstetrical Anesthesia at The Ottawa Hospital includes a group of physicians who provide a wide range of anesthetic and analgesic options for care during delivery. These include pre-operative consultation, complicated IV access, invasive blood pressure monitoring, patient-controlled analgesia, regional anesthesia (epidural and spinal) as well as general anesthesia. An anesthetist is present in the delivery room for all twin and multiples deliveries. 

A team of perinatal pathologists at CHEO provides diagnostic pathology services to obstetric patients for the Eastern Ontario region. Microscopic examination of unusual or abnormal placenta is provided for patients experiencing perinatal complications and detailed examination of the fetus is performed at the parent’s request in cases of fetal loss. Results of these examinations help the Maternal Fetal Medicine team gauge the risk to future pregnancy and plan therapeutic interventions to reduce future risk. 

A team of psychiatrists and psychologists provide consultation services for Maternal Fetal Medicine patients experiencing mental health difficulties throughout pregnancy and in the immediate post-partum period. These professionals are highly experienced in the management of psychiatric medications during pregnancy to minimize fetal risk. They work with community-based mental-health care providers to optimize the care of MFM patients following delivery. 

The Maternal Fetal Medicine team includes two nursing professionals who coordinate the care of our high-risk patients. They receive all patient referrals by fax and prepare all supporting documents for review and triage. Coordination of care includes patient advocacy, booking consultation visits, multidisciplinary referrals and appointments, arranging fetal therapeutic procedures and daily communication with physicians about ongoing patient issues during pregnancy. The nursing team provides supportive counselling to patients with special needs, such as those with structural differences or requiring fetal interventions like intrauterine transfusion.
