Summary

Limb reduction defects (LRD) occurred in 1.97% of perinatal autopsies. Low birth weight and threatened abortion were identified as key risk factors for these congenital anomalies.

Area of Science:

  • Medical Science
  • Pathology
  • Genetics

Background:

  • Limb reduction defects (LRD) are congenital anomalies affecting limb development.
  • Understanding the prevalence and associated factors of LRD is crucial for public health initiatives.

Purpose of the Study:

  • To investigate the prevalence and characteristics of limb reduction defects in a perinatal autopsy cohort.
  • To identify potential risk factors associated with LRD.

Main Methods:

  • A case-control study utilizing autopsy data from the University of Athens (1986-1990).
  • Analysis of 1725 perinatal autopsies to identify neonates with LRD.
  • Classification of LRD into five subgroups and assessment of limb involvement (upper, lower, or both).
  • Evaluation of coexisting nonlimb malformations and recognized syndromes.

Main Results:

  • 34 neonates (1.97%) presented with LRD.
  • Upper limb defects were most common (44.17%), followed by lower limb (41.17%) and both (14.70%).
  • 50% of cases had coexisting nonlimb malformations, including 5 with known syndromes.
  • Significant risk factors identified were low birth weight (≤2500 g) and threatened abortion.

Conclusions:

  • LRD represents a significant congenital anomaly with varied presentations.
  • Low birth weight and threatened abortion are critical risk factors requiring further investigation and potential intervention.
  • The findings highlight the importance of comprehensive perinatal autopsy in identifying congenital defects and associated conditions.
