Alterations of the Fetal Capillary Bed in the Guinea Pig Placenta Following Long-Term Hypoxia
Several pathohistological studies (Chabes et al., 1967; Salvatore, 1968; Hölzl et al., 1974; Kaufmann, 1982; Jackson et al., 1988; Kaufmann et al., 1988) concerning the maturation of the human placental villi provide evidence that there is a mutual relation between terminal villus development and capillary growth. Two types of fetal villous hyper-capillarisation have been described (Kaufmann et al., 1988) which are combined with typical patterns of terminal villus malformations:
Type a: abnormally long, largely unbranched, highly dilated capillary loops, and
Type b: dense, highly branched capillary networks, composed of short, narrow capillaries.
