Relation between serum PAPP-A level and umbilical cord thickness during first trimester of pregnancy

Abstract

Purpose: To evaluate the relation between umbilical cord diameter versus pregnancy associated plasma protein-A (PAPP-A) level in first trimester women. Method: Cord diameter were measured and patients were divided into two groups according to frequency distribution analysis as below or above 3.7 mm for free loop diameter (FCD) and below or above 3.4 mm for cord measurement at umbilicus (ACD). Groups were compared with each other. Results: Strong correlations were found between ACD versus PAPP-A. Conclusion: By using strong correlation between ACD versus PAPP-A, it may be possible to reduce unnecessary amniocentesis due to false positive screening results.
