Prenatal Diagnosis of an Intracranial Arteriovenous Fistula in the Posterior Fossa on the Basis of Color and Three-dimensional Power Doppler Ultrasonography

Prenatal ultrasound diagnosis of Down syndrome. After major malformations, soft markers, nuchal translucency and skeletal signs, a new vascular sign?

“…Since the beginning of the 1990s we have used routinely and encouraged others to use color Doppler ultrasound scanning as a part of the fetal examination18. This approach has allowed us to detect a number of anomalies on routine ultrasonography that are not always suspected on gray‐scale imaging, such as ventriculocoronary fistulae in second‐ and first‐trimester fetuses19–22, intracerebral23–25, intrathoracic26, or intrahepatic vascular lesions27, and aberrant left subclavian and right subclavian arteries28, 29.…”
