RESUMO
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. The diagnosis was based on color flow ultrasound with tracing along the course of cerebral arteries. Also, rendered 3D color flow ultrasound was helpful in demonstrating course of the vessels feeding the aneurysm and supporting the diagnosis. The aneurysm showed nature of rapidly progressive changes, leading to leakage resulting in intracerebral and intraventricular hemorrhage as well as high output state associated with anemia. Prenatal diagnosis and management are very challenging. This case ended up with planned delivery at 37 weeks, giving birth to a surviving male newborn, weighing 2600 g. The neonatal CT brain scans and CTA confirmed the prenatal findings. The prognosis was relatively poor because of extensive intracerebral hemorrhage with severe hydrocephalus and brain midline shift. The couple opted for neonatal palliative care without neurosurgical correction. CONCLUSION: This study demonstrate that the most important tool for prenatal diagnosis is color Doppler ultrasound, which will demonstrate turbulent blood flow. Three-dimension color Doppler ultrasound is helpful in supporting the diagnosis. The case presented here suggests that the disease has a natural course of rapid progression and massive brain destruction or high output congestive heart failure can be expected.

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. Shortly after leg and foot massage, she had a sudden onset of dyspnea, followed by consciousness alteration, brief spastic-like convulsion, became unconscious and suffered a cardiac arrest. Basic life support (BLS) at the event scene as well as during transfer and advanced cardiovascular life support (ACLS) at the hospital were provided, resulting in successful resuscitation but persistent coma. Bedside echocardiography showed poor contractility of the dilated right ventricle, and pulmonary embolism was suspected. CT angiography (CTA) revealed multiple concentric intraluminal filling defects within the right and left pulmonary arteries, indicating massive pulmonary embolism. The fetus died in utero and spontaneous labor and vaginal delivery occurred. CONCLUSION: Leg massage in patients with deep vein thrombosis can dislodge thrombi, leading to life threatening pulmonary embolism, and should be contraindicated. Since pregnant women are at a higher risk of undetected or subtle thromboembolism, traditional massage in pregnant women should be contraindicated unless they are proven to have no such risk.

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. The patients were categorized into two groups: placental penetration and nonpenetration. The rates of fetal loss, including abortion (<24 weeks of gestation) and fetal death in utero (>24 weeks of gestation), and other adverse pregnancy outcomes were compared between the two groups. RESULTS: A total of 21,566 procedures were performed during the study period. Of them, 8601 were excluded due to chromosomal/structural abnormalities, various underlying medical diseases and incomplete data or unavailability of final outcomes. Finally, 12,965 cases were available for analysis including 4692 (36.2%) in the group of placental penetration and 8273 (63.8%) in the group of nonpenetration. The abortion rate after amniocentesis trended to be increased in the placental penetration group (0.6 versus 0.4%, p = .064; RR: 1.60, 95%CI 0.97-2.64). Likewise, the fetal loss rate trended to be increased in the placental penetration group (1.0 versus 0.7%, p = .121; RR: 1.35 95%CI 0.92-1.98). Interestingly, preterm birth rate was significantly increased in the placental penetration group (13.8 versus 12.6%, p = .043; RR: 1.10 95%CI 1.00-1.20). CONCLUSION: Fetal loss rate was slightly increased, but not statistically significant, among the procedures with placental penetration. However, penetration of the placenta was slightly but significantly associated with an increase in rates of preterm birth.

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. The subjects whose menstrual age and ultrasound-based GA fell in different trimesters were excluded because the risk could not be calculated due to the different serum markers used in each trimester. The agreement of risk categorization for fetal Down syndrome was evaluated. RESULTS: The agreement of Down syndrome screening in the first and the second trimesters were 92.7% and 89%, respectively. The study found a good agreement of risk categorization by Kappa index, which was 0.615 for the overall screening. The menstrual age had a slight decrease in the detection rate and a lower false-positive rate. CONCLUSION: Menstrual age is acceptable in cases of accurate last menstrual period. However, in places where ultrasonography is not readily available, gestational age estimation by menstrual age along with clinical examination that corresponds to the gestational age can be reliable.
