Background: Chorionic villus sampling (CVS) and amniocentesis are two methods for prenatal diagnosis. The goal of this study was to compare amniocentesis and CVS-related complications in a large sample of Iranian women. Methods: Medical records of 1624 women who underwent amniocentesis or CVS due to medical indications between 2008 and 2016 were reviewed. Data regarding age, gravidity, parity, gestational age, type of procedure, neonatal weight (and percentile), trisomia, abortion, intrauterine growth restriction (IUGR), severe IUGR, preeclampsia, and gestational hypertension were recorded. Results: Finally, 1215 cases were evaluated. Mean maternal age, gravidity, and gestational age were significantly different between two groups. Preeclampsia, gestational hypertension, IUGR, severe IUGR, and intrauterine fetal death were not significantly different between two groups. Trisomy 18 and 21 were common in cases underwent amniocentesis. Conclusions: Women who underwent CVS are not at higher risk for developing hypertensive disorders than women underwent amniocentesis.

“…Small-sized needles have been associated with certain difficulties during the procedure. These include longer amniotic fluid aspiration times, primarily due to clogging and requirement for a second administration ( 8 ) . Our clinical experience with the 22 G spinal needle was somewhat similar, indicating longer aspiration time, clogging due to particulation, and requirement for further punctures; however, the retrospective design of our study did not allow for measurements of the exact aspiration time.…”

“…However, this is not supported by at least one study that reported more intrauterine (intra-amniotic) bleeding with needles of smaller size ( 2 ) . Moreover, investigations that included very small-gauged needles such as 29 G reported difficulties during myometrial passage and membrane puncture as the primary drawback ( 8 , 14 ) . Although there are some data on the cost effectiveness of karyotype analysis, needle costs have not been included in previous studies ( 12 ) .…”

Objective:To compare the short-term outcomes of two different-sized needles for genetic amniocentesis.Materials and Methods:A total of 271 amniocentesis were retrospectively evaluated in 2 groups concerning the size of the needles used during the procedure: Conventional 20-gauge (G) (n=164) and 22G (n=107). Periprocedural complications and cost-effectiveness were compared across the groups.Results:There were no differences between groups concerning complications within 15 days after the procedure (fetal loss, 0.6% versus 0.9%, and amniotic fluid leak 1.2% versus 1.8%, p=0.99 for each). The 22G needle was significantly more cost efficient (p<0.0001).Conclusion:The 22 G spinal needle is convenient for second trimester amniocentesis with similar complication rate and has a favorable cost profile.

“…Although it is done at a great number, there is still limited data today about the duration length of amniocentesis and the factors affecting the duration. [4][5][6][7] Therefore, the aim of this study is to reveal the factors affecting the duration length of amniocentesis performed for genetic purposes at second trimester.…”

Objective: Genetic amniocentesis is a method of prenatal diagnosis which is still the most commonly performed procedure today. The aim of this retrospective observational study was to analyze the factors affecting the duration of second trimester genetic amniocentesis. Methods:We evaluated the files of 117 patients in the study who undergone second trimester amniocentesis for genetic diagnosis. The duration that the amniocentesis needle was inside the uterine cavity and the duration of total procedure were both recorded and the correlation of these parameters with clinical and demographic characteristics was evaluated. For each patient, the indications for the procedure and clinical information were also registered. Results:The mean±SD values of 117 patients for age and the weeks of gestation were 31.7±5.4 years and 18.4±1.7 weeks, respectively. The mean±SD values of the time the amniocentesis needle was inside the uterine cavity and the total procedure time were 85.3±59.3 and 118.7±79.5 seconds, respectively. While there was no difference among the operators in terms of the duration that the amniocentesis needle was inside the uterine cavity (p=0.079), the total procedure durations were statistically different (p=0.004). The procedure was significantly longer in patients with vaginal bleeding prior to amniocentesis than in patients without vaginal bleeding before the procedure (115.0 vs 74.8 s; p=0.030). Both the appearance of the needle tip on ultrasound and the difficulty degree of procedure felt by the operators were found to have a significant impact on the duration of the procedure (p values were 0.024 and 0.030, respectively). Conclusion:The results of this study objectively show that second trimester genetic amniocentesis is a relatively short procedure. The difficulty degree of the procedure, the appearance degree of the needle tip on ultrasound and the presence of vaginal bleeding prior to the procedure affect the duration of the procedure. A larger scale prospective study is needed on the subject.
