چکیده
PURPOSE Amniocentesis (AC) and chorionic villus sampling (CVS) play an important role in the diagnosis of genetic anomalies. The aim of this study was to evaluate presentable numbers of procedure-related complications of genetic interventions in a tertiary referral hospital. MATERIALS AND METHODS The pregnancy outcome of women who underwent genetic AC or CVS during 2003-2010 at the Department of Obstetrics and Gynecology, Medical University of Graz, Austria, was analyzed retrospectively. The primary outcome was miscarriage or membrane rupture after an invasive procedure. Only singleton gestations were included. RESULTS 1,569 AC procedures and 334 CVS procedures (234 transabdominal, 99 transcervical, 1 with undocumented route) were performed. Of these, 57 cases were excluded from further analysis because of severe anomalies. Complete outcome data were available for 93.17% of cases. In 164 (8.89%) cases the pregnancy was terminated due to genetic anomalies or severe malformations. In the remaining collective 10 of 1,342 (0.75%) AC procedures, 3 of 150 (2.00%) transabdominal CVS procedures and 2 of 64 (3.13%) transcervical CVS procedures lead to complications resulting in miscarriage < 24 weeks (n = 13) or rupture of membranes (n = 2) within 2 weeks after procedure. Complication rates were significantly higher after CVS than after AC (OR 3.19). CONCLUSION Over an observation period of seven years, the complication rates after AC, transabdominal CVS and transcervical CVS were 0.75%, 2.00% and 3.13%, respectively. These results are comparable to recent international investigations.

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 ...

BACKGROUND A significant number of pregnancies are associated with the cytogenetic abnormalities of the fetus. Amniocentesis and chorionic villus sampling (CVS) are procedures used for prenatal genetic diagnosis. In this study, we compare the safety and complications of mid-trimester amniocentesis and transabdominal CVS. MATERIALS AND METHODS This analytic cross-sectional study was performed ...
متن کاملChorionic villus sampling
Chorionic villus sampling has gained importance as a tool for early cytogenetic diagnosis with a shift toward first trimester screening. First trimester screening using nuchal translucency and biomarkers is effective for screening. Chorionic villus sampling generally is performed at 10-12 weeks by either the transcervical or transabdominal approach. There are two methods of analysis; the direct...
متن کاملChorionic 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...
