Chorionic Villi Sampling

Research and Markets: Clinical Maternal-Fetal Medicine Online, Second Edition

DUBLIN--( BUSINESS WIRE )-- Research and Markets ( http://www.researchandmarkets.com/research/ac1fbd/clinical_maternal ) has announced the addition of the " Clinical Maternal-Fetal Medicine Online, Second Edition " book to their offering.

The new edition of this successful textbook is the comprehensive one-stop site to consult for any query relating to pregnancy and birth - a thorough and modern review of maternal-fetal medicine practice. The content includes diagnostic and therapeutic procedures used during pregnancy, such as ultrasound, chorionic villus sampling, amniocentesis, and fetal surgery. There is a major section on women with medical and surgical disorders, such as heart disease, high blood pressure, pre-eclampsia, diabetes, kidney or gastrointestinal disease, and infectious diseases. In addition, the book also covers the care of healthy women whose pregnancy is at markedly increased risk for adverse outcome from conditions such as multiple birth, recurrent pre-term labor and delivery, premature rupture of membranes, recurrent pregnancy loss, or fetal growth restriction. The basic sciences section have been enlarged to reflect how current understanding of maternal physiology and pathophysiology has resulted in more accurate diagnosis and more effective treatments of medical, surgical and obstetric maternal complications. More importantly, scientific advances have made the developing fetus in utero more accessible to evaluation, diagnosis and treatment. The book will be essential reading for trainees in maternal-fetal medicine and for a wide range of other clinicians and allied health workers in obstetrics, gynecology and women's health - all who have the privilege of caring for the unique symbiotic relationship between a mother and her fetus.

Key Topics Covered:

MODULE I Obstetric Disorders.

MODULE II Maternal Medical Disorders.

MODULE III Maternal Surgical, Malignancy, and Other Issues.

MODULE IV Genetics and Fetal Disorders.

MODULE V Fetal Assessment.

MODULE VI Perinatal Infection and Neonatal Disease.

Chorionic Villus Sampling (CVS)

Chorionic Villus Sampling (CVS) involves the retrieval of early placental cells which are cultured and examined to evaluate the baby’s chromosomes. It is done between 10 to 12 weeks and enables parents to get a result by the end of the first trimester, 7 to 10 days after the procedure is performed. Unlike the screening tests done via the mother’s blood and NT ultrasound which will only show

Diagnostic testing (amniocentesis and CVS) is considered medically indicated if a woman is greater than 35 years old in the United States, or greater than 37 years old in the U.K.  It is also offered to any woman who has a strong family history of certain abnormalities, or if the screening test comes back as ‘high risk’, which means the odds of the baby having a chromosomal abnormality are estimated to be greater than 1 in approximately 250. It is also likely to be offered if any anatomical abnormalities are found on the 11 to 12 week NT ultrasound .

CVS is considered slightly higher risk than amniocentesis and is usually only performed by perinatologists or high-risk practitioners. So, depending on your location and your health care provider’s preferences, it may only be an option for pregnancies that are at especially high risk, such as the mother being greater than 38 or 40 years old, or found to have very high risk results (greater than 1 in 100) on screening.

Keep in mind that most of the time, even when the screening test is positive, the baby is perfectly normal!!! Only 0.5% of fetuses are actually affected with Down’s Syndrome, yet approximately 5% of everyone who is screened will be found to be at high risk. Remember that CVS is an , available to you if you are deemed to be at higher risk of having a chromosomally abnormal baby. Since it carries a small but genuine risk of miscarriage, it is not a choice to be entered into lightly and is not something that your doctor or midwife wants you to do unless you are willing to take that risk.

CVS is always done under ultrasound guidance and can be done in two ways; vaginally or abdominally.  You will be instructed to arrive for your appointment with a full bladder which important to help position the uterus and optimize visualization of the structures inside. After taking a look with the ultrasound, the doctor will decide to pursue an abdominal or vaginal approach based on the position of the developing placenta. While you may prefer the idea of one over the other, you need to trust your doctor’s experience and confidence that he/she is picking the smoothest route to get a successful sampling of tissue. Like you, your doctor wants this procedure to be as easy as possible!
