title: Sonographic indications for karyotyping procedures. An international questionnaire.
abstract: An international survey was conducted to investigate attitudes to karyotyping procedures in cases of fetal anomalies detected by ultrasound. A questionnaire was sent to 111 current members of the International Society of Ultrasound in Obstetrics and Gynecology. The overall response rate was 48%. Analysis of the replies reflects a wide variation in the criteria for the definition of a sonographic abnormality, the indication for a diagnostic procedure, and the timing for intervention. The results emphasize the need for additional data on several sonographic findings (e.g. choroid plexus cysts, renal pyelectasis, short limbs) and for improved selection of patients for chromosomal investigation.
