Early Miscarriage: Morphological Data Useful to Clinical and Nosographic Classificati

The most frequent complication of the pregnancy is miscarriage. One in five pregnancies ends in miscarriage and the risk of recurrence increases with the increase of previous spontaneous abortions. In the present article an original checklist is shown to classify the causes of abortion based on morphological criteria that can be highlighted on abortive tissue. These histopathological elements are useful in distinguishing fetal from maternal causes of spontaneous abor- tions and those are used for a nosographic classification.
