chorionic villus sampling(CVS)

The dilemma of trans abdominal vs trans cervical chorionic villous sampling in posterior placenta cases . In regions such as the Middle East, where consanguineous marriages are common, it is obviously crucial to increase awareness of prenatal diagnostic procedures and their safety. Many patients, particularly in the Middle East, often refuse the CVS procedure unfortunately due to concerns stemming from recommendations by medical professionals who highlight unrealistic complication rates. I strive to inform patients that according to the Royal College of Obstetricians and Gynaecologists (RCOG), both amniocentesis and chorionic villus sampling (CVS) carry a minimal risk of miscarriage, typically below 0.5%. Additionally, teachings from the University of Barcelona suggest a risk of 1 in 1,000, which I believe is more accurate when performed by experienced practitioners. In my practice, I have never required local anesthesia, and patient satisfaction has consistently been high, with many expressing regret over the fears they experienced prior to the procedure. TA-CVS is generally favored over TC-CVS because it tends to be linked with fewer procedure-related fetal losses, a lower risk of bleeding and infection, a reduced need for multiple insertions, a higher success rate on the first attempt, and less maternal cell contamination. TA-CVS is considered as safe as amniocentesis, while TC-CVS appears to have at least a 1 percent greater risk of loss compared to amniocentesis. TC-CVS is technically easier to perform when the uterus is significantly retroflexed or the placenta is located posteriorly. It also results in less maternal discomfort and fetomaternal bleeding, and may be safer than TA-CVS when intestinal loops are observed between the abdominal wall and uterus. However, cervicovaginal issues (such as polyps, myomas, stenosis, or vaginismus) can complicate the TC-CVS procedure.
