Postnatal Intracranial Findings Following Fetal Repair of Spinal Dysraphisms.

Objective: Our objective is to document the imaging appearance in the intracranial compartment at the time of the infants' first postnatal brain MR imaging after fetal repair for spinal dysraphisms.

Methods: Twenty-nine patients were evaluated on fetal and postnatal magnetic resonance imaging for a series of features of Chiari II malformation.

Results: Of the 29 infants, 55% had resolution of tonsillar ectopia, and 62% showed a dorsal outpouching of the near the foramen magnum on postnatal magnetic resonance imaging.

Sonography-based Automated Volume Count to estimate fetal urine production in twin-to-twin transfusion syndrome: comparison with Virtual Organ Computer-aided AnaLysis.

Objective: Sonography-based Automated Volume Count (SonoAVC) is an automated, operator-independent, 3-dimensional ultrasound technique. The study goal was to assess agreement between SonoAVC and Virtual Organ Computer-aided AnaLysis (VOCAL) for bladder volume measurements and fetal urine production (FUP).

Study Design: This was a prospective study of recipient bladder volumes in twin-to-twin transfusion syndrome acquired with SonoAVC and VOCAL every 2 minutes during 30 minutes before and 24 hours after laser coagulation.

Treatment of twin-twin transfusion syndrome with proximate umbilical cord insertions.

Laser ablation of anastomosis is one method for treatment of twin-twin transfusion syndrome in monochorionic pregnancies. Sonographic mapping of the umbilical cord insertions is an important aspect of the preoperative workup before laser ablation. Proximate umbilical cord insertions can be potential contraindications to laser ablation.
