Prenatal features of aneurysm of the posterior cerebral artery: a case report.

Background: Fetal cerebral aneurysm other than aneurysm of vein of Galen aneurysmal malformation (VGAM) is extremely rare. This report describes prenatal features of aneurysm of the posterior cerebral artery (APCA) with rapid progression and its natural intrauterine course of the disease, which has never been reported.

Case Presentation: This is the first report of prenatal features of APCA, detected at 34-36 weeks of gestation, simulating choroid plexus cyst or arachnoid cyst.

Leg massage during pregnancy with unrecognized deep vein thrombosis could be life threatening: a case report.

Background: Traditional massage seems to be safe but not entirely risk free, though serious adverse events are very rare. This report is aimed at illustrating a rare but fatal presentation of massive pulmonary embolism caused by leg massage and also to encourage both massage providers and pregnant women to be aware of undetected or subtle deep vein thrombosis, which could be a life threatening condition as a consequence of leg massage.

Case Presentation: A 25-year-old primigravid Thai woman underwent massage at a traditional massage shop at 25th week of gestation.

A comparison of pregnancy outcomes after second-trimester amniocentesis between cases with penetration of the placenta and nonpenetration.

Objective: To compare the fetal loss rate associated with second-trimester amniocentesis between the procedures with penetration and nonpenetration of the placenta, as a primary outcome and to compare the rates of adverse pregnancy outcomes including preterm birth, fetal growth restriction and low birth weight, as secondary outcomes.

Method: A retrospective cohort study was conducted on women undergoing second-trimester amniocentesis. Our prospective database of amniocentesis, from January 1989 to December 2018, was accessed to retrieve the records meeting the inclusion criteria consisting of singleton pregnancies, gestational age of 16-22 weeks, and known obstetric outcomes.

Evaluating the Agreement of Risk Categorization for Fetal Down Syndrome Screening between Ultrasound-Based Gestational Age and Menstrual-Based Gestational Age by Maternal Serum Markers.

Objective: To evaluate the agreement of risk categorization for Down syndrome screening between ultrasound scan-based gestational age (GA) and last menstrual period-based gestational age in both first and second trimesters by maternal serum markers.

Methods: Data comprising 4,055 and 4,016 cases of first and second trimester screening were used. The maternal serum markers were analyzed using the ultrasound-based GA and menstrual age.
