Abstract:
The paper analyzes the data available in the literature on the possibilities of determining the time of fetal death during an autopsy study. It presents gross changes in the appearance and internal organs of the fetus, as well as histological changes in the organs and placenta, which develop during maceration. The microscopic characteristics of the development of lung and kidney tissues are given in relation to the gestational age of the fetus. Changes in the mass of internal organs during maceration, as well as their standard values are indicated depending on gestational age and degree of maceration.
