A comparison of pregnancy outcome between high-order multiple and twin pregnancies: matched-pair retrospective study.

Comparing Perinatal Outcome in Twin and Singleton Pregnancies Regarding Doppler Evaluation of Uterine Artery Indices in the Second Trimester

Background: Prediction of adverse perinatal and postnatal outcomes could be possible by using ultrasound Doppler evaluation, however there are some controversies regarding this issue in the literature. The goal of present study was to evaluate predictive value of Doppler indices in single and twin pregnancies during second trimester. Materials and Methods: This prospective study was conducted i...

Pregnancy Complications and Neonatal Outcomes in Multiple Pregnancies: A Comparison between Assisted Reproductive Techniques and Spontaneous Conception

Pnm-23: Ultrasound Evaluation of Multiple Pregnancies

Over the past 25 years the rate of twin and higher - order multifetal birth have increased between 1980 and 2005. The twining rate rose from 18.9 to 32.1 per 1000 live birth. Multifetal gestations are at high risk of fetaland complication such as; growth restricted fetal death, LBW and cerebral palasy. Maternal complication are that also increased such as: preeclampsia, diabetes, maternal death...

ارتباط حاملگی با تعداد جنین‌های منتقله در سیکل‌های ART

Background: The transfer of multiple embryos during ART procedures (IVF/ICSI) in order to maximize the chance of pregnancy, has resulted in increasing rates of multiple pregnancies with a 20- fold increased risk of twins and 400- fold increased risk of higher order pregnancies with significantly high maternal and perinatal morbidity and mortality in comparison with singleton. Since at pres...

Perinatal outcome of 12,021 singleton and 3108 twin births after non-IVF-assisted reproduction: a cohort study.

Perinatal outcome of pregnancies caused by assisted reproduction technique (ART) is substantially worse when compared with pregnancies following natural conception. We investigated the possible risks of non-IVF ART on perinatal health. We conducted a retrospective cohort study with two exposure groups: a study group of pregnancies after controlled ovarian stimulation (COS), with or without arti...
