Abstract The spread of both first trimester screening for chromosomal abnormalities and the possibility to check for single gene disorders at DNA-analysis has increased the request for chorionic villus sampling (CVS) in the first trimester. In order to perform placental biopsy, two routes are possible: the transcervical (TC) and the transabdominal (TA). In early days, the trancervical technique was the most diffused, but since its introduction into clinical practice, the TA technique has become… 

The decline of amniocentesis and the increase of chorionic villus sampling in modern perinatal medicine

An increasing prevalence of TA-CVS vs. amniocentesis for aneuploidy in the current era of prenatal testing is demonstrated and the importance of continuing to train specialists skilled in TA- CVS is underscore.

Efficacy, safety, and success of 18‐ versus 20‐gauge needle for transabdominal chorionic villus sampling in a high‐volume training setting

A retrospective study comparing TA-CVS samples obtained by the two different needle types, using an 18-gauge spinal needle in an attempt to improve the sampling success and to diminish the need for second sampling attempts to as well as to obtain greater quantity of chorionic villi, to facilitate the turnaround time for results.

In the authors' opinion, the recent ISUOG Guidelines on invasive prenatal procedures do not appear sufficiently well-structured to offer practical solutions regarding the best tools to use, the first-choice methods to employ and the indications to follow.

Invasive Diagnostic Testing

Invasive diagnostic testing used for chromosomal, Mendelian, metabolic, and congenital infective diseases is represented nowadays by three main procedures: chorionic villous sampling (CVS),

Invasive Diagnostic Procedures in Embryonic Period

In the era of prenatal ultrasound and biochemical screening, invasive prenatal techniques are the most appropriate procedures for diagnosing chromosomal, metabolic, and genetic fetal anomalies and DNA amplification by PCR and next-generation sequencing have shown high sensitivity and specificity for single-gene diseases.

Effects of Exogenous Progesterone on Fetal Nuchal Translucency Measured By 2d Ultrasonography

The mean nuchal translucency significantly increased in cases taking progesterone therapy in the first trimester, however, this increase was still within the normal range of NT and did not affect the risk of aneuploidy.

The diagnostic value of the early extended fetal heart examination at 13 to 14 weeks gestational age in a high-risk population

EFHE can work as a diagnose examination for most major CHD cases at GA 13 to 14 weeks by an experienced operator and may be applied in the first trimester, according to this diagnostic system for fetal CHD.

Guidelines for Invasive Prenatal Procedures



Nonabortal pregnancy complications of chorionic villous sampling

Currently chorionic villous sampling is the gold standard method of first trimester prenatal diagnosis and knowledge of the associated complications and their frequency is worth noting for both physicians and patients.

Early transabdominal chorionic villus sampling in couples at high genetic risk.

Method of sampling chorionic villi in first trimester of pregnancy under guidance of real time ultrasound.

The technique of chorionic villous sampling using real time ultrasound is simple to learn and yields material for biochemical analysis and chromosomal study without the need for tissue culture.

First 10 000 chorionic villus samplings performed on singleton pregnancies by a single operator

Chorionic villus sampling was performed in 10 000 consecutive singleton pregnancies by a single principal operator, working in two institutions, and Cytogenetic analysis was highly successful and accurate; however, in one case a de novo structural rearrangement of chromosome 1 was not recognized.

Randomized clinical trial of transabdominal versus transcervical chorionic villus sampling methods

The results of the study indicate that, if any, the relative risk of fetal loss following either procedure is less than double that of the alternative technique when performed by a skilled operator.

Chorionic villus sampling and acceptance rate of prenatal diagnosis

Compared the acceptance rate of fetal diagnosis for β‐thalassemia in three group of couples of Sardinian descent, results indicate that in this population, introduction of 1st trimester diagnosis made prenatal testing acceptable to practically all counselled couples at risk.

Learning in medicine: chorionic villus sampling

This study substantiates the presence of a learning curve for CVS and supports the view that centralization and restriction of CVS to a limited number of experienced operators within centres, is likely to have a positive influence on safety and success of the procedure.

Transabdominal chorionic villus sampling: Fetal loss rate in relation to maternal and gestational age

Considering that the total fetal loss rate before 28 weeks' gestation was on average 1.91 percent, it is believed that TA‐CVS is a safe and effective technique for prenatal diagnosis of genetic diseases.

Effective combined test screening for Down syndrome resulted in a significantly higher probability that an invasive test would confirm an abnormal fetal karyotype, provided it is safe, and not all countries were prepared for the effects of first-trimester screening.
