Pathology of the trophoblast and fetal vessels of the placenta in maternal diabetes mellitus

The morphologic characteristics of the chorial villi from normal full-term placentas and from placentas of different clinical types of diabetic women were studied. The latter showed early maturation of the trophoblast, higher percentage of villi with stromal edema, and higher percentage of vessels of the villous trunks with lesions causing partial or total obstruction of the vascular lumen. The fact that the diabetic patients were treated suggests that the metabolic correction of diabetes mellitus prevents the occurrence or development of the multiple disturbances which the disease produces in the evolution of human pregnancy.
