Abstract

HISTOLOGICAL, changes have been investigated in the postmature human placenta. This is an obstetric abnormality known to be associated frequently with antenatal asphyxia and stillbirth. Fœtal loss occurs as a result of hypoxia, attributed to functional placental insufficiency1–4. It is generally stated that in postmaturity the placenta displays signs of ageing and degeneration: widespread vascular obliteration, thrombosis and infarction with excessive fibrinoid and calcined deposits. The appearance of ‘young’ placental villi in postmaturity, reported by certain investigators5–7, does not seem to have received adequate attention.
