VP40.17: Ultrasound prediction of the large‐for‐gestational‐age fetus

Cardiac ultrasound of the fetus.

Assessing the 'at-risk' fetus: Doppler ultrasound.

PURPOSE OF REVIEW Doppler ultrasound has become an indispensable tool in evaluating pregnancies at risk for conditions such as preeclampsia, intrauterine growth restriction, fetal anemia, and umbilical cord abnormalities. Use of umbilical artery, middle cerebral artery, and uterine artery Doppler has been the mainstay of assessment. RECENT FINDINGS Recent findings promote the use of ductus ve...

Ultrasound contributions to the management of the severely isoimmunized fetus.

Twenty-four out of 81 fetuses affected by anti-D isoimmunization underwent ultrasonic guided intrauterine transfusions (2.8 I. U. T.s per fetus). The absolute value and trend of delta OD 450 micron value was correlated with the severity of fetal condition as evaluated by ultrasonography following simple semiquantitative grading of ascites (mild, moderate, severe) and diagnosis of hydrops. The e...

Ultrasound imaging of the early fetus : is it safe ? REVIEW

Diagnostic ultrasound has an excellent safety record in general and, in particular, in obstetrics. As a form of energy, ultrasound has effects in insonated tissues that are caused by two main mechanisms: thermal and nonthermal (also known as mechanical). Onscreen indicators of these potential bioeffects are the thermal and mechanical indices. Biological effects of ultrasound have been reported ...

Evaluation of ASGE Criteria for Prediction of Choledocholithiasis: Can Early Endoscopic Ultrasound Utilization Make the Prediction More Accurate?

Background: ASGE predictive model for the detection of choledocholithiasis is a reasonable approach for the management of patients with cholelithiasis. Surgeons do not pursue cholecystectomy without evaluation of the biliary system when laboratory tests and diagnostic imaging evidence show biliary duct involvement. Literature revisions reveal that the prediction of choledocholithiasis based on ...
