Current Perspectives of Prenatal Sonographic Diagnosis and Clinical Management Challenges of True Knot of the Umbilical Cord.

摘要: Umbilical cord accidents preceding labor are rare. Single and multiple nuchal cords, true knot(s) of the umbilical cord, often incidental findings noted at delivery non-hypoxic non-acidotic newborns without any evidence subsequent adverse neonatal outcome. In contrast to single knots which occur in between 0.04% 3% all deliveries, have been associated with a reported 4 to 10 fold increased risk stillbirth. First real-time ultrasound, current widespread application color Doppler, power Doppler three-dimension sonography, has enabled increasingly more accurate prenatal sonographic diagnoses cord. Reflecting inability visualize entire ultrasound assessment, despite detailed second third-trimester scanning, many occurrences knot remain undetected only delivery. Although diagnostic accuracy is increasing, false positive diagnosis cannot be ruled out certainty, must continue considered clinically. Notwithstanding diagnose knots, currently there clear absence clinical management guidelines by governing bodies regarding patients whom / suspected. As result, units, suspected suggestive or consistent disregarded, not documented, uniformly informed this potentially life-threatening condition, carries an considerable This commentary will address perspectives challenges singleton pregnancies.
