Amniocentesis and Chorionic Villus Sampling

Comparison of Complications of Chorionic Villus Sampling and Amniocentesis

A cost-effectiveness analysis of amniocentesis and chorionic villus sampling for prenatal genetic testing.

Amniocentesis and chorionic villus sampling are tests for the prenatal diagnosis of cytogenetic abnormalities. We calculated the incremental costs per abnormal birth averted, and the incremental costs per quality-adjusted outcome, of amniocentesis and chorionic villus sampling performed for the indication of maternal age. Probabilities were obtained from the literature, and direct medical costs...

مقایسه پیامدهای بارداری در دو روش تهاجمی آمنیوسنتز و نمونه‌برداری از پرزهای جفتی در فاصله سال‌های 1390-1380

Background: Chorionic villus sampling refers to a procedure in which small samples of placenta are obtained for prenatal genetic diagnosis, generally in the first trimester of pregnancy in 11 weeks till 13 weeks+6 days. This procedure provides prenatal diagnosis in pregnancy. Amniocentesis is a technique for windrowing amniotic fluid from the uterine cavity using a needle via a trans abdominal ...

Infant morbidity following amniocentesis and chorionic villus sampling for prenatal karyotyping.

OBJECTIVE To investigate whether amniocentesis and chorionic villus sampling increase the risk of postural deformities, limb reduction defects, respiratory problems in the newborn, fetal and infant mortality, prematurity, low birthweight and fetal distress, and to investigate the impact of gestational length at the time of the procedure. DESIGN A population-based cohort study. SETTING Swede...

SOGC CLINICAL PRACTICE GUIDELINES Amended Canadian Guideline for Prenatal Diagnosis (2005) Change to 2005-Techniques for Prenatal Diagnosis

Invasive prenatal diagnosis techniques include chorionic villus sampling (CVS), amniocentesis, cordocentesis or percutaneous umbilical blood sampling (PUBS), fetal tissue sampling, as well as embryoscopy and fetoscopy (Table 2). Some diagnostic results may be obtained by more than one technique: for example, fetal karyotype can be obtained from cells from amniocentesis, chorionic villus samplin...

Chorionic Villus Sampling

Chorionic villus sampling (CVS) is a test used for prenatal diagnosis [5]. Safe to perform at an earlier stage in pregnancy [6] than amniocentesis, CVS is another invasive prenatal diagnostic test that can be performed as early as ten weeks after the woman?s last menstrual cycle. While this test does carry some risks, it is generally very effective at predicting heritable diseases during or soo...
