RESUMO
BACKGROUND: A fetus is defined from 8 weeks after conception until term while in the uterus. Fetal death is defined as death of the fetus before the complete expulsion or extraction from the mother, irrespective of the duration of pregnancy that is not an induced termination of pregnancy. The causes of fetal death determined after fetal autopsy can be categorized according to the classification proposed by Cunningham and Hollier as fetal, placental, and maternal. METHODS: All fetuses dying in utero, that is, prior to birth, regardless of the gestational age, to the mothers admitted in the Department of Obstetrics and Gynecology along with the respective placentas were received in the Department of Pathology, MGM Medical College, Aurangabad, after an informed and written consent from October 26, 2017, to October 30, 2019, and were included in this study. Clinical details along with obstetric history and antenatal ultrasonographic findings were also recorded. Anthropometric examination of the fetus was performed and evisceration was then done using the Rokitansky technique. Representative sections from each of the organs were taken and kept in tissue cassettes and processed for routine hematoxylin and eosin staining. RESULTS: This study was done on 33 cases of fetal death. Most fetal deaths occurred in the gestational age between 15 and 19 weeks (14 cases [42.42%]) and the least amount during 35 to 39 weeks (2 cases [6.06%]). The cause of death could not be ascertained in 6 cases (18.18%), whereas the maximum cases had fetal factor as the cause of death (15 cases [45.45%]). Maternal causes were seen in only 4 cases (12.12%). Gestational hypertension was seen to be the most common maternal factor associated with fetal death, which comprised 24.24% of cases (8 of 33). Thirteen of the total 33 cases did not have any associated obstetric complication. Of the total 33 fetal deaths, only 7 had associated placental defects on gross examination. Twenty-six placentas did not show any gross abnormality. Of these 7 cases, 5 were seen to have placental infarction. CONCLUSIONS: Fetal autopsy is a valuable and cost-effective modality for the confirmation of cause of fetal death. Fetal autopsy can also prove beneficial to the parents in planning for future pregnancies. Fetal autopsy can serve as the ultimate tool in diagnosing cause of fetal death in cases where no other diagnostic clue is available. Therefore, it should be encouraged and couples to be counseled regarding its importance and clinical utility.
