[...]... diabetes mellitus, obesity, and hypertension may have their origins in abnormal placental development This is the first book devoted exclusively to the anatomy, physiology, immunology, and pathology of the placentalbed Experts in clinical andbasic sciences have made important contributions to bring, in a single volume, a large body of literature on the normal and abnormal placentalbed Thus, readers will... persisted, and in particular the understanding of the anatomical structure of the ‘curling’ arteries remained incomplete and often not based on data Therefore as an introduction to the chapters on placentalbed vascular disorders the early literature on the maternal blood supply to the placenta is briefly reviewed The term placentalbed was introduced 50 years ago by Dixon and Robertson [2] and can be... that the placentalbed is such a battlefield that fetal and maternal tissues are hard to distinguish on biopsy material and maternal vessels are disrupted after placental separation In 1958, independent from the British group in Jamaica, the Department of Obstetricsand Gynaecology of the Catholic University of Leuven had also started to collect placentalbed biopsies, and in 1963 they began to collect... re-examination of the original histological sections of Hertig and Rock [17] cast doubt on the drawings published by these authors in 1941 and the existence of such shunts was later disproved Recently, Schaaps and collaborators [19] used threedimensional sonography and anatomical reconstruction to investigate the placentalbed vasculature and demonstrated an extensive vascular anastomotic network in the myometrium...

In the initial studies of placentalbed uteroplacental arteries in preeclampsia Dixon and Robertson [2] and Brosens [3] assumed that the response of the arteries to placentation was similar to that in normal pregnancy and the investigators were looking for typical hypertensive vascular lesions However, after the identification of the physiological changes in the placentalbed spiral arteries [4] (Fig... arteries in the placentalbed in association with preeclampsia and fetal growth restriction and the methodology of placentalbed vascular studies are reviewed Defective myometrial spiral artery remodeling in preeclampsia Research on the presence and extent of physiological changes in the spiral arteries in the subendometrial myometrium was based on 15 hysterectomy specimens and over 300 placentalbed biopsies .
