Abstract

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 approach. Amniocentesis and chorionic villus sampling are invasive prenatal procedure. Their complications are fetal loss vaginal bleeding, rupture of membrane chorioamnionitis and limb reduction. There are some probable predictors of fetal loss after chorionic villus sampling and amniocentesis including maternal age, gestational age, number of needle insertion, previous miscarriage, and placental location. The aim of this study was to compare procedure related complications of amniocentesis and chorionic villus sampling in a tertiary referral hospital in Iran.

Methods: This retrospective cohort study was done in pregnant women who were high risk in genetic screening tests. The pregnancy outcome of women who underwent amniocenthesis and chorionic villus sampling was assessed in Yas Women General Hospital (Mirza Kuchak Khan), Tehran, Iran, from 2001 to 2011. Group one, pregnant women who underwent amniocentesis, was compared with group two, pregnant women that underwent chorionic villus sampling. The statistical analyses were performed with SPSSv.20 using a significant level of α<0.05.

Results: There were no significant differences between the two groups in procedure related fetal loss before 24th weeks of pregnancy (1.1% in chorionic villus sampling group versus 0.6% in amniocentesis group, P=0.318). A significant relationship between the number of needle insertion in the chorionic villus sampling group and fetal loss before 24th weeks of pregnancy was seen P<0.028. There were no significant differences between the two groups in the occurrence of vaginal bleeding, rupture of membrane, pre-term birth, placenta location, low birth weight and very low birth weight. The risk of chorioamnionitis was higher in chorionic villus sampling group (P=0.019). No significant difference was observed between the liquid and bloody amniotic fluid and pregnancy complications.

Conclusion: There was no significant difference between the procedure related complications of amniocentesis and chorionic villus sampling.

Abstract
Background: Complete molar twin pregnancy with coexisting fetus is a rare and important diagnosis in obstetrics. Preeclampsia, preterm labor and life-threatening vaginal bleeding are the serious complications of this type of pregnancy. Gestational trophoblastic neoplasia should be ruled out after termination of pregnancy. In this study we reviewed a molar twin pregnancy with a live coexisting triple x fetus which has not been reported till now.
Case Presentation: Our case was a 22-year-old primigravida woman and 17-18th week of pregnancy, who referred to an University Hospital in Mashhad, Iran with complaint of vaginal bleeding On October 2016. Her first trimester ultrasonography in 13th week of gestational age, reported a live single fetus with an anterior great placenta and cystic formation regarding molar pregnancy. According to above-report, Amniocentesis was done in 15th weeks of pregnancy and its result was triple X. After severe and life-threatening vaginal bleeding, she underwent an emergent hysterotomy. A fetus with no obvious anomaly and a great hydropic and vesicular placenta delivered. Episodic crisis of her blood pressure was best controlled with anti-hypertensive drugs. In our case, chemotherapy with methotrexate was started after poor decline of βHCG titration and definite diagnosis of gestational trophoblastic neoplasia. Remission was completely achieved after four courses of chemotherapy.
Conclusion: Differentiation between complete molar pregnancy with live fetus and partial mole is always challenging in obstetrics. Serious complications as preeclampsia and severe vaginal bleeding may become life-threatening. Coexisting molar pregnancy should be ruled out in a pregnancy associated with frequent and unexpectant vaginal bleeding. Amniocentesis and an expert radiologist can help to differentiate them. Following these patients is very important to reveal any trophoblastic neoplasia.
