摘要
Abstract
Objective To study the age-specific morphology of fetal umbilical vein and to provide evidence for clinical wide use.
Methods Fresh umbilical veins obtained from 33 cases of 32 - 42 weeks old were sliced with paraffin section methods. The section
preparations stained with HE and special methods was measured using light microscope and image analysis system. Results
Umbilical vein wall, media membrane, and smooth muscle widened with age. The cellular nuclear numerical density(CNND) and
the celldar nuclear area density(CNAD) are the greatest at the age of 37 - 40 weeks. Conclusion The smooth muscle, CNND and
CNAD are increased with fetal age, suggesting that it is advisable for the choice of 37～40-week-old umbilical vein as grafts.关键词
