Case ReportsPrenatal diagnosis of a bronchogenic cyst in an unusual site.
We report a rare case of a subdiaphragmatic cyst, diagnosed prenatally during routine ultrasound screening at 25 weeks' gestation. Serial ultrasonographic evaluation demonstrated a slight increase in the size of the cyst during pregnancy. On the basis of the anatomic site and the sonographic features of the lesion, four diagnostic hypotheses were postulated: cystic neuroblastoma, adrenal hemorrhage, duplication of the inferior third of the esophagus and retroperitoneal cystic lymphangioma. ⋯ He underwent successful surgery at the age of 3 months. The post-operative course was uneventful and the baby is currently doing well. Histology revealed a bronchogenic cyst.

Randomized Controlled Trial Clinical TrialEffects of low-dose aspirin on uterine and fetal blood flow during pregnancy: results of a randomized, placebo-controlled, double-blind trial.
This study was conducted to evaluate uteroplacental and fetal hemodynamics in fetuses exposed to low-dose aspirin (100 mg/d). ⋯ Daily administration of low-dose aspirin during the second and third trimesters of pregnancy does not alter uteroplacental or fetoplacental hemodynamics and does not cause moderate or severe constriction of the ductus arteriosus.

Prenatal diagnosis of placenta previa accreta by transabdominal color Doppler ultrasound.
The aim of this study was to evaluate the efficacy of transabdominal color Doppler ultrasound in diagnosing placenta previa accreta. ⋯ Variable vascular morphological patterns of placenta previa accreta were exhibited and categorized by transabdominal color Doppler sonography in the antenatal period. The identification of these specific vascular patterns had a positive impact on the peripartum clinical management of the affected patients.
